How Wolves Change Rivers

[EagleSmack]

Yes. I live in a prime example. The Arrow Lakes are part of the Columbia River. The climate has radically changed since they dammed the river at Castlegar creating a 200 km. long reservoir. .

The "climate" has changed because of a dammed river?


Oh brother


Let's start offing beavers then!

Me I am rather partial to beaver ya know.

How Wolves Change Rivers

Yep, I read a report on that very issue some years back. Cool, huh?

The microclimate in the central Kootenays has, yes. http://people.uleth.ca/~rood/PolzinRivers(Kootenay).pdf

But it has nothing to do with quadrupling the water volume of the Columbia river? The water level was raised by 70 feet. The surface area of the lakes was more than doubled. There is hardly any part of the Columbia that runs as a river any more. Most of it is behind massive dams. One of the world's largest interior salmon fisheries has be eliminated which also altered the flora and fauna of the region.

You should torch it all while you still have the chance.

Yes. I live in a prime example. The Arrow Lakes are part of the Columbia River. The climate has radically changed since they dammed the river at Castlegar creating a 200 km. long reservoir. We used to live in an interior rain forest similar to the BC coast but now we get less than 1/4 the rain and snow we used to, the river no longer freezes and the old species of rain forest trees, like cedar and hemlock, are dying off, ground water levels are dropping.

I lived here in the Caribbo for about 30 years now, Cliffy and I have seen similar changes in the biosphere here too. Die back of the once prevalent Cedar forests was all ready underway when I first arrived here. Now it is rare to find a healthy stand of Cedar in our area. About a decade or so ago something attacked all our Aspens. Shortly after the leaves reach full bloom, we begin to see what look like raised snail tracks covering every single leaf on every single tree. It doesn't kill the Aspens but it ruins their once lovely appearance and in the fall instead of turning the brilliant yellows they once did the leaves are now a dirty burnt orange and the color change begins much earlier than it once did.

The same thing has been happening here but it seems to affect all deciduous trees. The trees all look like they are dying by mid August. Also, I didn't have any mosquitoes last year and the swallows never came back. Vultures started nesting here for the first time about 5 years ago and last summer I saw about a dozen circling over a field. Everything around here is screwy.

Maybe they are just reclaiming their own.

There are a lot of 'birders' around here and in the last couple of years they have mentioned the scarcity of swallows here too. They also seem to be seeing a lot more species who do not normally spend time in our area.

About three years ago I was on my way to town when I happened to be looking out the window and saw what I thought - though couldn't believe - was a vulture circling over a rancher's field. Watched it for as long as I could then continued on my way and thought nothing more of it until the following week when an article in our local paper caught my eye. Apparently a vulture had been seen in several areas around 100 Mile lately - some quick thinking fellow got a pretty good photo of it and sure enough it was a vulture. Since then a few more have been seen especially in calving season.

Turkey vultures.

Damn ugly beasts. They've made their way back to the prairie a few years ago.

Species species-16

The turkey vulture is a large raptor that feeds exclusively on carrion. It searches for carrion by soaring in forested and open habitats, using vision and smell to locate food. Its highly developed sense of smell allows it to find food in dense coastal forest. The turkey vulture nests in caves in cliffs or bluffs, under boulders on rockslides, in large cavities in hollow snags or, occasionally, in dense vegetation on the ground. Its nesting habitat requirements in B.C. are very poorly understood, but in general western populations are thought to use mainly caves for nest sites. In B.C., it nests as isolated pairs. The breeding season extends from early April to late August. The turkey vulture roosts communally at night during migration, and during cold wet weather it may remain in the roost all day.

Actually Eagle the busy little beaver has a lot to do in an ecosystem . Trapping the beaver created desert like conditions in the Caribou region of British Columbia in the 1800's and the reintroduction of the beaver late in the century allows it to thrive as the great cattle and wildlife areas of our province that it is .

You must be trapping those beaver again .

B.S. their were tons of swallow when I went through last summer .

And their population is growing because they are making a living . They have been around B.C. for like ever , but are becoming a more common sight. I think road kill probably plays a roll .
