Feb 2, a noteworthy date, for what reason?

 Feb 2 is well-known for being Groundhog day. But is it really that important of a day to recognize? Will whether the groundhog sees its shadow or not, really be an accurate forecast of what is ahead for the remainder of winter?

I rather doubt it. 

Perhaps the best thing about the attention given to groundhog day is that it provides us something to talk about during this normally long period of winter, when many are patiently waiting for spring!

Perhaps a much more important day on Feb 2 is the recognition of it being World Wetlands Day. Wetlands include coastal marshes, flooded forests, wet prairies, bogs, peatlands, etc. Wetlands are some of the most important elements of nature for so many reasons. For example they are indirectly the source of our drinking water. They harbour thousands of native species, both plant and animal, many of which are declining and at risk. They prevent flooding. They filter out sediment and pollutants from entering the rivers and lakes. They store carbon.

Canada is home to about 70% of the world's freshwater wetlands. We have been blessed far more than we realize, yet wetlands are constantly under threat of increased pollution and loss. They are being invaded by aggressive non-native flora and fauna. They are an easy target for conversion to some other purpose, including agriculture/commercial/industrial/residential development.

This next photo shows the same creek system, from the same spot, during a high water flood event only 5 days earlier, due to the heavily drained/tiled lands upstream.

This next photo show the invasion of non-native Phragmites into a high quality wetland along Lake St. Clair.

Exploring accessible wetland areas are immensely important for a person's mental and physical well being. For example watching a sunrise or sunset is generally a healthy event for a persons mental health, but when viewing it in a wetland setting increases its value.

 The greatest amount of freshwater wetlands in Canada are in the far north. In Ontario this includes the Hudson Bay Lowlands as shown by these next two photos taken while I was on a wildlife survey project at Polar Bear Provincial Park in the early 1990s.


At the opposite end of the province is Fish Point Provincial Nature Reserve at the southern tip of Pelee Island, with a small but quite functional and important wetland.
And in between, are many wetlands that feature that Canadian icon, the Canadian Beaver.

 The central parts of Ontario are well endowed with small lake/wetland complexes.

Other wetlands feature wildlife such as the Common Gallinule, a species easily heard, but not often seen.

Rare species such as orchids occur in quality wetlands. This next photo shows a person (centre right) involved in a survey for the endangered Eastern Prairie White-fringed Orchid at a wetland in Chatham-Kent.....

Ground-hog Day or World Wetlands Day....take your pick

Yesterday, Feb 2, was Ground-hog Day. While I don't want to denigrate the ability of those furry rodent prognosticators across the land in speculating the arrival of spring, perhaps just as importantly, it was another notable day: World Wetlands Day.

There is a worthwhile blog post about wetlands on the Canadian Geographic site, located here.

Wetlands, and of course the lakes, rivers and streams that they are often associated with, are critical to a lot of life, including yours and mine. In fact the survival of most plant and animal life is dependent to varying degrees, on water.

Here in Chatham-Kent, at the time of settlement, according to a 1987 paper, the landscape was made up of 66% wetland, which includes both marsh and swamp. By 1967, only 5% remained and by 1982, that number had dropped further to 3.7%. I don't have figures for the current status, but I expect we have all seen more wetlands disappear than re-appear on the landscape, and there are continuous threats to those few remaining wetlands. For a municipality with less than 5% natural area, not a lot of that is in wetland form, so it is fair to say that wetlands have declined significantly since 1982.
St. Clair area wetlands
In the early 1970s, 21 participating nations met in Iran, and established the Ramsar Convention, which is more formally known as the Convention of Wetlands of International Importance. Its purpose was to be a treaty for the conservation and sustainable utilization of wetlands for their economic, cultural, scientific and recreational values. Wetland sites were nominated across many of the participatory nations, which typically were some of the most nationally and internationally significant sites.

Some of the wetlands in Chatham-Kent and neighbouring counties were nominated, but currently only two have been adopted as a Ramsar Site. They are Point Pelee National Park and St. Clair National Wildlife Area.

The wetlands along the eastern and northern sides of Lake St. Clair are well known for their attraction to migrating and nesting waterfowl. Some of the stats regarding its significance (based on the Ramsar Convention website) are:
  • 25% of the North American population of Tundra Swans pass through the area;

Resting swans and geese

  • over 200,000 Canada Geese pass through the area.

  • up to 360,000 individual waterbirds pass through the area, including Canvasback, Redhead and Mallards. During the most recent Christmas Bird Count for this area, on January 1, 2016,  our one day count of waterfowl totalled over 55,000 birds. In 2007, our one day count totalled over 95,000 birds!

In addition there are numerous species of wildlife besides waterfowl as well as plants that are dependent on these vast wetlands, including many species at risk such as Swamp Rose Mallow, where at times, can be incredibly profuse as this next image shows. The Canadian range of this species is largely limited to the more significant wetlands of extreme southwestern Ontario.

At the opposite extreme of the province is one of the largest wetland complexes in Canada: the Hudson Bay Lowland. Polar Bear Provincial Park is a huge part of the Hudson Bay Lowland with an area of almost two and a half million hectares, and is Canada's second largest Ramsar site. (The largest is the Queen Maud Gulf in the NWT, which encompasses over 6 million hectares). I was privileged to have spent several weeks in Polar Bear PP doing some wildlife surveys in the early 1990s. It is an incredible place.


The numbers of shorebirds and waterfowl are amazing. For example, on migration, more than one million Snow Geese pass through, and some breed here in huge colonies.

During migration, the area supports almost the entire Arctic population of Red Knot.

It also supports the entire Arctic breeding population of Marbled Godwit.

In spite of the recognition of these internationally significant wetlands, so many other significant wetlands of southwestern Ontario have been lost, or are threatened and may be gone tomorrow, or next year. These losses are attributed to our economic development of the area, including agriculture and urbanization. We are all at least partially responsible, and the decline in habitat quality and species diversity continues. Yet I read just today of a prominent spokes person for the industry stating that to demonstrate the environmental responsibility of his industry, the evidence is in the increasing numbers of frogs, birds and other animal populations on the landscape.

Huh???

No examples were provided, because to this person, it was evident by just looking around. I'm not really sure what that person was looking at, however, as the overwhelming evidence is exactly the opposite. Our native populations of flora and fauna have been in decline for decades, and show no signs of letting up. In fact the number of officially, legally Rare, Threatened and Endangered Species has never been higher, and there are dozens and dozens of other species waiting to be evaluated to determine their status. The only thing that is increasing on the landscape is the abundance of non-native invasive species. And that will be discussed in another post.
