Declare Your Favourite Lake or Water Body by Signing the Love My Lake Declaration


As lakes across Canada started to phase from water into ice earlier this month, I asked if any of you has a favourite lake or water body. I also mentioned that Nature Canada is introducing the first national Love My Lake Declaration. Well now I'm back to invite you, your friends and family, your co-workers and your fellow freshwater-lovers to sign it!

The Declaration represents a list of people from coast, to coast, to coast (and beyond!) who want to declare their love for Canada's lakes and other (fresh)water bodies. Simply fill out and submit the form below and voilà, you've made official your love of Canada's aquatic environments - in all their wondrous and valuable forms.

Last week I shared my fervor for two Canadian waterscapes: Frozen Ocean Lake in Kejimkujik National Park, Nova Scotia and Big Trout and Trout Lakes in Ontario's Algonquin Provincial Park - and I've already added them to the Declaration. But let's not 'dam' the enthusiasm for waterscapes there... add your favourite lake or water body now!

So don't click away until you've had a chance to sign the Declaration below! Check back soon for an update on how many Canadian waterscapes have been listed.


Canadians love their waterscapes, and here's your chance to tell
us which lake or water body in Canada is special to you and why. Simply fill out the form below to add your name to the national 
Love My Lake declaration.

Do you have a favourite lake or pond?

Ice formation, Stan Wojtaszek
With Fall well underway, Canadians are saying "see you soon" to lakes and ponds all across the country for yet another winter. Swimming, paddling, fishing and visits to the lakeside cottage have, among other things, been put on hold for awhile. But now is a great time to reflect on the many ways that lakes and ponds help us connect to nature throughout the year; how they are part of our experience of the 'true north, strong and free'. And I can't forget all the opportunities lakes offer for pond hockey, ice-fishing and skating during the winter months!

Canadians love their waterscapes, it's pretty much a fact. Saskatchewan-based author Allan Casey explores the almost intrinsic relationship Canadians have with lakes and other water bodies in his 2010 Governor General's Award-winning book Lakeland: Journeys into the Soul of Canada. Through a series of encounters with several of Canada's lesser-known but nonetheless well-loved lakes, Casey explains how lakes are an integral part of the Canadian experience. In the opening chapter he writes:
"Like a lot of Canadians, I have been drawn irresistibly to lakes my whole life. Access to pure lakes is fundamental to my quality of life in my home and native land. I love them all." (from p.2)
That excerpt resonates with me in many ways. I didn't grow up on a lake, nor did I grow up with a lakeside family cottage or taking annual paddling trips or attending summer camp. But I did grow up with fond memories of lots of time spent at lakes and ponds, giving me a great appreciation of them as accessible water bodies. For me lakes were not the ocean, which in my experience on the Bay of Fundy was an all-at-once powerful, beautiful and merciless body of water. Lakes were by no means innocuous in my mind, but they were more palpable, more enjoyable - they were more fun.

With my training in environmental science and biology, lakes came to mean even more to me and my experience as a Canadian. Lakes are so much more than just bodies of water or habitat for "fish". You can read all about lakes as habitat and how to promote healthier human and wildlife habitat along Canada's shorelines at The Living By Water Project. You may also be interested in a report our own Ted Cheskey recently co-authored, called Birds At Risk: The Importance of Canada's Boreal Wetlands and Waterways.

Since expanding my perspective on lakes, I've become an avid paddler (whenever I get the chance) and I love exploring lakes in search of birds, fish, crustaceans, freshwater molluscs, dragonflies and other invertebrates, submergent and emergent plants, solace, recharge... you name it. And now as a parent I have the opportunity to see lakes through my daughter's eyes. I look forward to our first paddling trip together, or the first time we skate on a wide open pond. We had lots of fun this summer exploring lakes in baby-steps (literally) and finding out how fun it is to get Mummy and Daddy wet.

Do I have a favourite lake in Canada? Absolutely! I love a waterscape called Frozen Ocean Lake in Kejimkujik National Park, Nova Scotia. I have fond memories of introducing good friends to open water paddling on that lake, and the back-country campsites are amazing! I also love Big Trout and Trout Lakes in Ontario's Algonquin Provincial Park. And I'm always glad to expand this list!

So, do you have a favourite lake or pond? If so then stay tuned to our blog. Why? Because we're starting Canada's first 'Love My Lake' Declaration - a list of people who want to declare that Canada's lakes are special to them. Check back soon for more details on how you can get involved!

Is There a Dark Side to Springtime?

By March I've usually had my fill of snow, so I tend to welcome the annual spring melt -- but wait, is there a dark side to spring? One environmental chemist says so.

From a University of Toronto Scarborough press release:
“During the winter months, contaminants accumulate in the snow,” says [University of Toronto Scarborough (UTSC) environmental chemist Torsten] Meyer, an expert on snow-bound organic contaminants and a post-doctoral fellow at UTSC. “When the snow melts, these chemicals are released into the environment at high concentrations.”
In a specially designed, temperature-controlled laboratory at UTSC—which includes a homemade snow-gun and a chemical pump—Meyer creates large baths of fresh snow already tainted with organic contaminants. This one-of-a-kind set-up enables the researcher to slowly melt his “dirty” snow, collect the melt-water and track which chemicals emerge from the snowpack and when.

Meyer’s research reveals a worrying surprise. “One of the main findings is that there is a peak contaminant flush at the very beginning of the melt,” he says. With the advent of spring, according to Meyer, comes a deluge of pollution.

By the time snow has turned black with muck and grime, many harmful chemicals — including those from pesticides, car exhaust, telecommunications wiring insulation, water repellent clothing, paints or coatings — may have already seeped out of the snow and into the surrounding ground water or surface water.

Contaminant-laden early spring melts are particularly ill-timed for many aquatic organisms, who are at a vulnerable stage in their life cycle. As Meyer points out, his findings could be used to reduce that risk to wildlife -- for example, municipalities can choose snow dump sites that are well-contained to protect against that early flush of pollutants.

Take the Plunge – Pledge to Save Water on World Water Day

With some of the most beautiful and ecologically important rivers, lakes and wetlands in the world, Canadians have many reasons to celebrate World Water Day. From the mighty Mackenzie River in the north, to the wetlands of the boreal forest, and the Great Lakes, our country lays claim to 60% of the world’s fresh water.

Yet a recent survey found that Canadians use twice as much water as people in France and the Czech Republic. A seemingly limitless supply of this natural resource means some of us don’t think twice before watering the lawn in the middle of a hot summer day, or letting the tap run as we brush our teeth.

But those small actions add up – it’s time for us to let go of the myth of water abundance.

Fortunately, it’s easy to make a few small changes to your water consumption around the house that can make a big difference. Take Nature Canada’s water pledge to use water wisely in and around your home and save 10 gallons (38 litres) a day.

These are some EASY ways that you can save water around the house:

  • Don’t run the tap while shaving or cleaning your teeth – save 1 gallon (3.7 litres) a minute
  • Add an aerator to any tap – save 1 gallon (3.7 litres) a minute
  • Reduce the length of a shower by one minute – save 2.5 gallons (9.5 litres)
  • Install a low flow shower head – save 3 gallons(11.3 litres)a minute
  • Install a toilet tank displacement device – save.5 gallon (1.8 litres) a flush
  • Run the dishwasher only when it is totally full – save 10 gallons (37.8 litres) each saved load
  • Water your lawn at night and save 65% lost to evaporation when watering during the day – save 5 gallons (19 litres) a minute

To date, 2,942 people have pledged to save a total of 40,805,540 litres. Take the plunge and make your pledge today!

Have a Happy World Water Day!

Happy World Wetlands Day!




Source: Ramsar Convention on Wetlands

Today is the 40th anniversary of World Wetlands Day, which marks the signing of the Convention on Wetlands of International Importance (Ramsar Convention) in Ramsar, Iran.

Forty years ago today, 18 countries met to establish the Ramsar Convention. Since then it has grown to include160 member countries. Their work has resulted in 1, 912 wetlands of international importance, a.k.a Ramsar Sites. To date, this covers an area greater than 186 million hectares. In Canada there are a total of 37 Ramsar Sites covering more than 13 million hectares. Their designation as Ramsar Sites does not entitle them to national legal protection, unless they are within established protected areas.

A news release issued by the Ramsar Convention on Wetlands, eloquently outlines the vital role wetlands play in maintaining a healthy and thriving planet:

“They include lakes, rivers, ponds, marshes, swamps, peat bogs, beaches, reefs, mangrove forests … and more. There is no doubt that wetlands are among the world’s richest ecosystems, supporting all humankind in various ways – by providing freshwater, supporting fisheries including aquaculture, helping to regulate the water cycle, providing flood and storm protection, supporting some of the world’s most stunning biodiversity, playing a significant role in climate change mitigation and adaptation, providing sustainable livelihoods to some of the world’s poorest people, and offering a place to ‘play’ for those of us with leisure time. Wetlands are indeed more than just a muddy swamp – many economists looking at the ecosystem services they deliver put their value higher than for any other ecosystem. Yet wetlands continue to be destroyed to make way for inland and coastal developments and degraded through poor water allocation decisions, pollution, and excessive water extraction.”

The slogan for World Wetlands Day 2011 is “Forests for Water and Wetlands”, which unites this celebration with the United Nations declaration of 2011 as the International Year of Forests. The purpose of this year's theme is to highlight the benefits that forested wetlands have to offer, how forests (wet and dry) play a role in our lives and how they’re important for the functioning of wetlands.

World Wetlands Day is a great opportunity for governments, NGOs and citizens to take action to raise awareness of the global importance of wetlands and the critical role they play in our well-being. To view activities taking place during WWD click here.

Looking Deeper Into Fish Lake

  
Grizzly bears are one of the
species identified by the
Prosperity Review Panel
that would be adversely affected
by development at Fish Lake.

The government of Canada made a good decision earlier this week when it turned down a proposal for an excessively damaging mine at Fish Lake, British Columbia. Nature Canada congratulated Environment minister Jim Prentice for respecting the conclusions of the federal environmental assessment of the project, and for respecting the will of First Nations about land use in their territory. Looking deeper into the context of that decision reveals some important insights and implications.

Environmental assessment works
While the process of environmental assessment may seem mysterious from a distance, Nature Canada has been up close and personal with it many times over the years and we are convinced it works. Environmental assessment allows independent panels to consider expert testimony, reach conclusions about the likely environmental impacts of a proposed project, and identify mitigation measures that could limit the damage. The resulting recommendation to the government (and it is only a recommendation) can range from approval of the project, to approval on the condition that certain mitigation measures be required, to rejection of the project as proposed.

Politics happens
The government must then decide whether or not to accept the recommendations about the studied project, and this is where the hard facts of environmental assessment meet the vagaries of politics. The government can follow the recommendations completely, partially, or not at all. But thanks to the public nature of the assessment process, we the citizens know whether or not our government is approving projects that destroy our environment. This is where the vagaries of politics meet accountability to the voters. In the case of Fish Lake, Minister Prentice deserves credit for doing the right thing for Canada, despite pressure from within his own caucus to do otherwise.

More to come
Nature Canada is very engaged in two other environmental assessments that are awaiting a response from the federal government: proposed gas drilling in the Suffield National Wildlife Area, and the proposed Mackenzie gas project.

In the case of the Suffield NWA, the environmental assessment report concludes that the proposal to drill 1,275 gas wells would interfere with the purpose of the National Wildlife Area. It also recommends that the government complete overdue work to identify the critical habitat of species at risk, and take other conservation action even if the project does not proceed. We are hopeful that Minister Prentice will accept all of this panel's recommendations too, reject the gas drilling project, and take other actions to better protect the national wildlife area.

In the case of the Mackenzie gas project
, the federal government has been accused of attempting to secretly make the panel rewrite some of its recommendations. This suggests a lack of appreciation for a key feature upon which citizens depend: the independence of environmental assessment panels. We congratulate the panel for standing up for the their independence in the interest of Canada. We hope Minister Prentice will show leadership and convince his cabinet colleagues to accept the panel's report. You can help us encourage the government to stop the Mackenzie Gas Project and to instead establish protected areas in the Mackenzie Region that will be safe from development.

Changing the rules
Parliament will soon be undertaking a review of the Canadian Environmental Assessment Act. There is cause for concern, since the government already used the budget bill to weaken the Canadian Environmental Assessment Act earlier this year. You can be certain that Nature Canada will be working to ensure the review results in a stronger act, not a weaker one.

Back to the lake(s)
The decision about Fish Lake is a good news story, and we hope it does not go down in history as a rare exception. A loophole in the law that protects fish habitat, the Fisheries Act, allows the government to exclude some lakes from the protections of the act and let mining companies use lakes as dumps for toxic mining waste. A handful of lakes has been targeted so far, including Fish Lake in BC and Sandy Pond in Newfoundland and Labrador. We are concerned that this loophole threatens pristine lakes across Canada. Now that Fish Lake has been spared, it's time to take action on the others.

Government Rejects Prosperity Gold-Copper Mine; A Victory for Fish Lake

Nature Canada is pleased to learn of the Government of Canada's decision to reject Taseko Mines Ltd.'s proposed gold-copper Prosperity Mine in British Columbia. The proposed mine would have led to the transformation of Fish Lake into a 'tailings impoundment area', i.e., a mining waste dump site, under the Metal Mining Effluent Regulations (MMER) of the Fisheries Act.

We applaud Environment Minister Jim Prentice for considering the adverse environmental impacts of the proposed mine, as concluded by the Federal Review Panel, as well as respecting the importance of Fish Lake to the Tsilhqot'in First Nation.

In an announcement made yesterday, Environment Minister Jim Prentice said "the significant adverse environmental effects of the Prosperity project cannot be justified as it is currently proposed."

There are now questions on the future of mining investments in BC according to an article in The Vancouver Sun

Water - We Can't Live Without It!

Without clean, abundant freshwater, life on Earth would not exist. The majority of the world's population depends on freshwater environments to provide water for drinking, irrigation, food, employment and recreation.

Luckily, Canada is blessed with plenty of water:
  • Almost 9% (891 163 square kilometers) of Canada's total area is covered by fresh water.
  • Wetlands cover an additional 14% (more than 1.2 million square kilometers) of the land area of Canada.
  • Annually, Canada's rivers discharge 7% of the world's renewable water supply – 105 000 cubic meters per second.
Balanced, healthy ecosystems, including freshwater rivers and lakes, perform many amazing services that cannot be replicated – and that we depend on for survival. In Canada, these ecosystems:
  • purify the air and water
  • maintain biodiversity
  • control agricultural pests
  • preserve soils and renew their fertility
  • pollinate crops and natural vegetation
  • and much more...
These services are so fundamental to life that they are easy to take for granted, but we must remember that they are far beyond the ability of human technology to replace.

The way we treat our water resources can have an effect on healthy ecosystems. Runoff of pesticides, fertilizers and waste, introduction of non-native species and destruction of wetlands all reduce the ability of water ecosystems to perform their functions and provide these services.

We can all protect our freshwater resources through conservation action at home. Do your part to reduce global demand on our precious water resources - take the Water Conservation Pledge today! Join people across the country and around the world as we save more than 1 million gallons of water each year.

This post is a part of Blog Action Day, an annual event that sees blogs from around the world post about the same issue on the same day to spark global discussion and drive collective action.

At Least Some Mines Get Fines Instead of Permits Under the MMER

Last week, Saskatchewan’s La Ronge provincial court declared Claude Resources Inc. guilty of three offences under the Metal Mining Effluent Regulation (MMER) of the Fisheries Act in relation to activities at Laonil Lake. The Saskatchewan-based mining company’s Seabee gold mine in northeastern Saskatchewan violated the MMER by: 1) depositing an acutely lethal effluent; 2) exceeding prescribed limits for effluents that contain total suspended solids; and 3) failing to report that their monitoring tests showed exceeded limits.

Apparently, Environment Canada and Saskatchewan Environment have tried for some time to get the company to become more compliant with regulations but without success. As a consequence, legal action was taken and Claude Resources Inc. was fined $90,000, of which $40,000 will be paid as a fine, and $50,000 to be given to the Saskatchewan Wildlife Federation.

Canada’s lakes and rivers are facing an imminent threat from Schedule 2 of the MMER which was introduced in 2002. Schedule 2 is a list of Canadian lakes that were reclassified as “tailing impoundment areas” - a mining waste site, under the MMER of the federal Fisheries Act.

There are prohibitions in place thast prevent the pollution of waters known to be fish habitat listed under section 36 (3) of the federal Fisheries Act. However, dumping is permitted under section 5.1(a) and Schedule 2 of the Fisheries Act’s MMER. Schedule 2 of the MMER allows lakes listed under it to be exempt from protection against the “depositing deleterious substances” into fish habitat under section 36(3) of the Fisheries Act. To date, there are 15 lakes in the provinces of Manitoba, British Columbia, Newfoundland and Labrador and Nunavut listed under Schedule 2.

Raising A Green Fledgling - Part 4 - Fried Green Diapers

Hello Readers!

This week's Raising A Green Fledgling installment focuses on green diapering. It can be a messy topic but no worries, we'll keep it nice and clean. Which takes me to the title of this week's post. Why "fried green diapers"? It's simple really, but you'll have to read on to find out why.

Cloth/reusable diapers seem to be enjoying a resurgence after years of high consumer demand for convenient, disposable diapers. I think this resurgence makes sense both environmentally and practically, but it's worth exploring some other perspectives on this, especially since there can be substantial up-front costs for cloth/reusable diapers.

A 2009 research review called Diapers and the Environment, from the Massachusetts-based group NEARTA, compared disposable and reusable diapers in four areas: solid waste, non-renewable resources consumption, airborne/water-borne wastes, and water consumption. The authors' showed that reusable diapers had fewer negative environmental impacts than disposables in the first three areas, while there was no advantage for either type of diaper with respect to water consumption.

Alternatively, the UK Environment Agency showed that reusables can be better or worse than disposables in terms of their negative environmental impacts. In a 2006 study, An Updated Lifecycle Assessment Study for Disposable and Reusable Nappies (Aumônier et al), the Agency concluded that "consumers' behaviour" largely determined the negative environmental impact of reusables over time. Translation: the impacts of reusables vary based on how you wash, dry and hand them down over time, not to mention the appliances you use and the electricity and water you use to rinse, wash and dry them (and where the electricity and water come from). Other life cycle assessments of disposables and cloth/reusables have failed to find a clear front-runner, as well.

Fair enough. Reusable diapers do require a lot of rinsing, washing and drying, multiple times per week. And rinsing a reusable can consume more water once baby is on solid food. Hot water washing (w/ cold rinsing) is also recommended to remove stains from reusables. Finally, you shouldn't mix regular laundry with reusables because they require less detergent and detergent that is less harsh and free of synthetic chemicals (see RAGF Part 2). Detergent residues left after washing can decrease the absorbency of reusables and may lead to skin irritation.

But I was perplexed that life cycle assessments would fail to name reusables the clear winner. I mean, disposables generate so much MORE persistent, non-degradable waste than reusables, right? And disposables may take up to 500 years to decompose and break-down into tiny bits of plastic that persist in the environment. Most disposables also contain super absorbent polymer (SAPs) compounds that solidify to gel once 'activated', adding additional chemical waste to the mix.

Reusables range from being 100% composed of natural fibres to being a clever mix of natural and synthetic fibres. They're typically designed with an outer cover and an absorbent insert, both of which are washable. While the synthetic components of reusable diapers have life cycle impacts similar to those of their disposable counterparts, reusables produce far less waste at the end of product life and can be re-used by multiple babies over time in a family. Try that with a disposable.

My wife and I considered the waste our reusables might generate if we tossed them out with this week's trash (assuming we were bonkers). We estimated the waste at less than one regular-sized garbage bag, and that's based upon one-size-fits-all reusables that will last us at least until our daughter's first birthday. Plus we can re-use them with future children. Using some of the estimates presented in the research above, a typical baby goes through 70 to 80 disposables per week. That's easily enough to fill 52 regular-sized garbage bags in that same one-year period. One garbage bag compared to 52 for the same period amounts to a lot more impact from disposables in my mind. A 2004 World Health Organization study said that disposable diapers are the "third largest individual constituent of municipal solid waste" making up "over 4%" of the total amount.

So notwithstanding water consumption, I don't buy the conclusion that disposables and reusables have equal environmental impacts. But that's just my opinion, and you know my bias. I also can't get beyond the fact that disposable diapers effectively 'lock-up' biodegradable human waste for hundreds of years, while reusables often liberate that waste into sewerage systems where it can be treated and/or biodegraded more readily.

I haven't talked about the difference in cost between disposables and reusables, but it's enough to say that reusables have a greater up-front cost. However, this cost is usually amortized, or spread-out, over the baby's entire diaper-wearing life. And the diaper-wearing lives of its younger siblings. Disposable diapers cost less per unit in the beginning but become more expensive as baby grows, and they have to be newly purchased newly when they run out. NEARTA conducted another research review, Diaper Cost Comparison, which reported these conclusions. The review also points out the costs associated with water and electricity consumption for laundering reusables, including the cost of using a cloth/reusable diaper cleaning service. This is certainly not insignificant in every case.

As for our experience with reusable diapers so far: they're wonderful. We're happy about the reduced waste associated with reusables, which allows us to feel like responsible environmental stewards. On the practical side, we're very impressed with how well reusables work and how little odor they have when soiled. Our daughter seems to love them, too. They're not messy and rarely leak if fitted and fastened properly, plus many of the new outer cover materials prevent external soaking. We use a non-airtight diaper pail lined with a washable diaper bag to store soiled diapers, and control occasional odors between washes by using drops of tea-tree oil in the bag. We also use washable cloth wipes with an all-natural diaper wipe spray, and we found great all-natural, biodegradable bamboo baby wipes to use as an alternative when not at home.

There's one other huge benefit to cloth/reusable diapers: they motivate toddlers to potty-train earlier since there are no super absorbent polymers and moisture-wicking membranes to make baby feel dry even though he/she's not. Yes, you have to pay more attention to the state of baby's diaper this way, but it's worth it in the longer-term I think.

Oh yeah, what about the title of this week's post? Well, fried green diapers refers to a trick that comes in handy with reusables. Normal washing and drying often won't remove all stains from reusable diapers, but the sun does a remarkable job of naturally bleaching them. So whenever possible, we line-dry our diapers to make sure they stay looking as good as new. I think "fried green diapers" nicely describes this process, since the sun 'fries' our 'green' diapers. :-)

Disclaimer: This is by no means a comprehensive look at the benefits and pitfalls of cloth/reusable diapering. There are numerous maternity stores, baby shops, boutiques and other retailers that can help you navigate the world of cloth/reusable diapers and I encourage you to seek the advice of their experienced staff. A simple Google search will help you find a retailer or cloth/reusable diapering blog or forum in your region.

Canada's Birds Feel the Impact of BP Oil Spill - Profile #5

This is the fifth species profile in this series highlighting migratory birds that may be at risk during their fall migration through the oil spill in the Gulf of Mexico.

Northern Gannet

With its striking plumage – pure white with black wingtips and bold lines around blue eyes – it is hard to miss the Northern Gannet. This remarkable species spends most of its life at sea and nests in a few large colonies in the North Atlantic. It feeds by plunge-diving up to depths of 22 metres in pursuit of fish.

Most adults had already made their migration north, away from the Gulf, in April before the oil spill began. However, juvenile gannets remain in those dangerous waters and were among the first avian victims of the spill. The fall migration back to the Gulf occurs in October. There is no way of knowing whether the effects of the spill will be cleaned up by then, but the damage to the species' future has already been done.

Canada's Birds Feel the Impact of BP Oil Spill - Profile #4

This profile is the fourth in the series highlighting Canadian migratory species that may be in harm's way as they migrate through the Gulf of Mexico and the area affected by the BP oil spill this fall.

Sanderling

The Sanderling is one of the most widespread shorebirds in the world. This small, plump sandpiper can often be seen running along the coast in flocks. Sanderlings feed by probing the sand along the tideline with their bills, chasing after receding waves to pick up stranded crustaceans and molluscs.

An Arctic breeder, this species is common all along North American coasts during migration. Their spring migration, from late April through May, fell right at the start of the oil spill in the Gulf. Waves that formerly deposited food on the beach to fuel the rest of their journey instead deposited sticky slicks of oil that stained the birds a rusty orange.

For those individuals that did make it to their breeding habitat in the Arctic, the fall migration back south takes place through July and August for adults and lasts through August and September for juveniles. As the spill continues to spread away from its epicentre in the Gulf, more of the American coast that these birds will use as stop-overs on their journey to wintering habitats in Central and South America is becoming toxic.

Canada's Birds Feel the Impact of BP Oil Spill - Profile #3

This is the third bird profile in the series highlighting species that may be at risk from the BP oil spill during their fall migration from Canada through the Gulf of Mexico.


Yellow Rail (Special Concern)


Small, with buff, yellow and black plumage that mimics the tall grasses it hides in, the Yellow Rail breeds in isolated pockets across Canada's boreal forest. This marshbird, the second-smallest rail in North America, is rarely seen and quite secretive, but depends on the coastal wetlands in the Gulf of Mexico during the winter.

If oil begins to accumulate in the marshes along the Gulf coast, recovery would be difficult or impossible since so little is known about this species.

Another Fake Lake?

Mining company Taseko plans to reclassify two interior BC waterbodies, Fish Lake and Little Fish Lake, as tailings impoundment areas (toxic waste dump sites!) and create an artificial lake as compensation for the resulting loss of fish habitat. However, a recently released report from the Canadian Environmental Assessment Agency reviewing the Project stated "that the Project would result in significant adverse environmental effects," calling into question Taseko's plans.


One specific adverse effect of reclassifying Teztan Biny (Fish Lake) and Y'anah Biny (Little Fish Lake) into tailings impoundment areas is "the destruction of approximately 90,000 rainbow trout" which is "an important food source (for First Nations) when salmon populations are low." The creation of the replacement lake, called Prosperity Lake, would not "adequately mitigate the losses of the fishing and recreational experience at Teztan Biny (Fish Lake)," the Panel found.

The Tsilhqot'in First Nation, local community, and environmental groups are strongly opposed to the Project for numerous reasons.


The creation of tailings impoundment areas out of pristine Canadian lakes and rivers has received more attention as industry further exploits the Metal Mining Effluent Regulations, Schedule 2 "loophole" of the federal Fisheries Act. Some lakes that were destined to perpetual toxicity are being spared, such as Bamoos Lake in northern Ontario. Others require long legal battles and strong public support with an unpredictable end, such as Sandy Pond, in Newfoundland.


The plaintiff in that case, the Sandy Pond Alliance (including Council of Canadians, the Sierra Club of Canada, the Newfoundland and Labrador Natural History Society, MiningWatch Canada, and others) is arguing that "it is illegal for the federal government to allow the dumping of mining waste into Canadian lakes and rivers." The Alliance hopes to put an end to the practice of converting Canadian lakes into mining waste dumps once and for all.


If they succeed, Taseko will have to explore other waste management options around the Prosperity Lake Project. MiningWatch Canada has more information and details on how to send a letter to the Prime Minister, the Minister of the Environment and your MP to deny approval to this damaging project.

This profile is the second in a series highlighting some of Canada's migratory species that may be affected by the BP oil spill in the Gulf of Mexico.

Roseate Tern (Endangered)

The Roseate Tern is similar in appearance to several other species of tern, with its black cap and long forked tail, but has a distinctive chi-vik or ki-rik call. This species feeds by plunge-diving, dropping into the water from heights of up to 12 metres to catch small fish.

These terns pass through the Gulf of Mexico, heading north in April to breeding sites in Nova Scotia and coastal New England, and south in September to wintering grounds in South America. If oil remains on the water when their fall migration begins, the birds are at risk of becoming oiled and ingesting oil as they try to feed. Even if the surface effects of the spill have been cleaned up, they may still be at risk from eating contaminated fish.

Canada's Birds Feel the Impact of BP Oil Spill - Profile #1

The BP oil spill began during spring migration season for many birds that breed in Canada during the summer, and with oil continuing to spill into the Gulf, the coming fall migration seems poised to be a dangerous time for Canada's migratory birds. This weekly series of profiles will highlights some of the species most likely to be in harm's way.

Piping Plover (Endangered)

In Canada, this small, sandy-coloured shorebird breeds on open sandy beaches of lakeshores, river sandbars, ocean coasts, and alkali flats in scattered locations on the Atlantic coast, on the Great Lakes and in the prairies. Its plumage would seem to blend right in, if not for the bright orange legs. They often walk or run along the sand, rather than flying, to take advantage of this camouflage. Piping Plovers feed on marine worms or small crustaceans by a series of rapid steps and pecks on the sand.

Piping Plovers spend their winters mainly on the Atlantic and Gulf coasts of the United States, Mexico and Cuba, particularly on beaches, mudflats, sandflats, bays, lagoons and inlets. Their spring migration peaks during mid-April; while many individuals would have already left the Gulf when the leak at Deepwater Horizon began, some may have been caught in the spill.

Although the fall migration peaks in August and September, plovers can begin to leave their breeding grounds as early as June or July if nest conditions have been unfavourable. These birds are heading straight to a region where their habitat and food sources may have been compromised and are still at risk from oil contamination.

The Gulf Oil Spill is a Disaster that Can't be Repeated

On April 20, the world awoke to a developing tragedy triggered by an explosion on BP's Deepwater Horizon oil drilling rig in the Gulf of Mexico. Recent estimates put the total amount of the spill between 160 million and 320 million litres so far, more than four times the amount of the Exxon Valdez spill. We still don't know when the flow of oil into the Gulf will stop.

Oil has already reached a dozen Important Bird Areas (IBAs) in Louisiana, Mississippi, Alabama, and Florida. The oil has damaged coastal grasses and sea grass beds that are vital nursery grounds for fish and shrimp and provide habitat for numerous other animals and plants. The loss of these critical sources of food could have devastating consequences for many bird species that depend on the Gulf coast region.

You can get up to date information on the oil spill's path on the National Audubon Society's website, as well as first-hand accounts of clean-up efforts underway.

In just a few short weeks, the first migratory birds will begin their journey south from Canada to their wintering grounds in South and Central America. Many of them rely on the impacted region to gather and feed during their journey.

As birds arrive in the disaster zone, the oil spill will affect them in a number of ways:
  • An inability to fly due to oiled feathers
  • Hypothermia induced by oil on their feathers
  • Poisoning from ingesting oil while preening
  • Poisoning from eating other contaminated wildlife
  • Disturbances during rescue efforts

It will be months, if not years, before the full impacts of this oil spill are known. In some cases, we may never know the extent of the effects on particular species.

What lessons can Canada learn from this disaster?

The tragedy unfolding in the Gulf of Mexico is a reminder that offshore oil drilling is never safe for the environment or for the communities along our coasts. Oil in the water is dangerous for fisheries, wildlife and ecosystems no matter where it happens.

Perhaps the greatest danger lies in drilling in the Arctic region. A spill in the Arctic would have devastating consequences for the region's fragile wildlife and ecosystems, and no technology exists that could clean up a spill in so inhospitable an area. The techniques deployed in the Gulf – even there not nearly successful – would be useless in the Arctic.

Just weeks before the Gulf of Mexico oil spill disaster, BP was actively lobbying the Canadian government to ease some of the planned rules for Arctic Ocean oil and gas exploration, and had already acquired three offshore exploration licenses for the Canadian Beaufort Sea.

Unlike the United States, Norway and Britain, Canada lacks a regulatory process governing whether or where oil and gas development can happen in the Arctic. Licenses are granted, and contracts signed with oil and gas companies before any environmental assessment takes place. The result: exploratory licenses exist in environmentally sensitive areas like the Beaufort Sea, where a blowout would have immediate negative effects on the delicate ecosystems there.

The disaster in the Gulf is a wake-up call. It is time to place a moratorium on new offshore drilling, including the Arctic, and to end our reliance on dirty, polluting fossil fuels in favour of responsible development of clean, renewable energy.

In the near term, no new exploratory licenses should be granted and no applications approved until the National Energy Board completes its review of Arctic safety and environmental offshore drilling requirements. A moratorium should also be in place until an independent commissioner is appointed to hold a review of offshore drilling on all of Canada's coasts.

And of course, a permanent ban should be in place prohibiting any oil and gas drilling inside a recognized protected area, and that prohibits any future exploration licenses from being granted within protected areas.

What has happened in Gulf is truly tragic; the Canadian government and industry should do all it can to put the environment and worker safety first so that a similar disaster doesn't happen off Canada's shores.

Top Tips for Nature-friendly Spring Cleaning

It's the time of year when we want to start fresh, shake off the chill of the past winter, and brighten up our surroundings. It's time for spring cleaning!

It's important to think about the effects on the environment as we clean our homes. Commercial cleaners that end up running down the drain with our wash water can end up in rivers and lakes. Harsh chemicals and artificial scents can become airborne, harming our own health and that of wildlife in our neighbourhoods. One-time use solutions clutter landfill sites.

It's easy to clean your home using items you already have in your kitchen cupboard. These solutions should start to tackle cleaning jobs around the house, leaving both you and nature happier this season.

All-purpose cleaner
A 1:1 mix of white vinegar and water in a spray bottle will tackle most household cleaning chores. If you don't like the smell of vinegar, add a few drops of your favourite essential oil (choose tea tree oil if you're looking for a natural disinfectant). Also use vinegar to clean stainless steel appliances, chrome fixtures, and to remove rust.

Wood that shines
Traditional wood polishing sprays leave a cloud of chemicals in the air rather than treating your furniture. Mix up your own polish with 1 cup of olive oil and a squirt of lemon. Rub on to your treasured pieces with a soft cloth to restore their glow.

One of our eNews readers, Patricia, prefers to use pure coconut oil instead of olive oil for polishing wood surfaces. Let us know if you have any other natural alternatives to these tips!

Skip the disposables
Dedicate some reusable cloths to cleaning, and run them through the washing machine (cold water, line dry!) when they get a bit grubby. If you're looking for added cleaning power, microfiber cloths have a natural charge that attracts dust and can be used dry or damp. Even better, make your own cloths from old towels and keep even more waste out of the landfill.
