Climate Change and Wildlife Habitat

These days we often here talk of climate change and the potential impact that global warming will have on our society. But what about the affect of climate change on wildlife and wildlife habitat.

According to Dr. Paul James, Director of Environmental Monitoring for the Province of Saskatchewan and a research fellow at the University of Regina, many of our wildlife species are completely dependant on a very narrow band of acceptable climactic and environmental conditions in order to survive. Serious study of the effects of climate change on habitat must be undertaken and planning models must be tuned to reflect the new reality.

In short, when an ecosystem undergoes a dramatic change it can no longer sustain resident and migratory wildlife populations. New species of plant and animal life take over and indigenous species disappear.

So why don’t animals and birds simply move as their habitat changes? The fact is that they do, and much can be learned by the studying the slow migration of species into regions where they were previously unknown. But what happens if they can’t move? Take the animals and birds of the northern tundra for example. They rely on food sources that are only produced in regions of permafrost. As the permafrost vanishes due to sustained periods of higher than normal temperatures new types of vegetation will take over. These species simply cannot move further north to find food sources because it will simply cease to exist.

Species like the ptarmigan, arctic fox, and polar bear will simply cease to exist. And guess what? It is very likely to happen in our lifetime. Many scientists firmly believe that this is a “when”, rather than an “if” scenario.

There are other fragile ecosystems like the prairie pothole region that runs from the north central US through Southern Manitoba, Saskatchewan, and into Southern Alberta. This ecosystem provides a stopover for almost every migratory bird along the Mississippi flyway accounting for 80% of the waterfowl in North America. This ecosystem is already at risk due to improper farming and development practices. Over the next 50 years the potholes that provide a safe secure stopover for a wide variety of waterfowl will simply cease to exist.

Don’t take my word for it! Do your own research and form your own opinion, but you will find that in spite of government rhetoric many of these changes are inevitable. Dr. James stated “Wildlife studies must now focus on how to plan for the new reality and forget about sustainable management models of the past.”

While governments dither, wildlife habitat disappears!

Optics for your Outdoor Adventures

Whether you’re hiking the rugged Bruce Trail, paddling the Grand river, or hunting in the farmlands of Southern Ontario a high quality pair of binoculars or spotting scope should be an essential part of your outdoors gear.

There are two schools of thought when it comes to binoculars; compact or full size. If you can manage a full size pair, that definitely is the way to go. Although you can buy some very high quality compact binoculars that will get the job done, the only real advantage they offer is the fact that they are indeed compact.

Full sized glasses allow for a larger objective lens; this is the end closest to your subject, providing the viewer with a crisper clearer image while capturing more light. This is particularly important during those times just before dawn and just after sunset when light begins to diminish.

People often get confused over the meaning of those numbers like 10x32 or 8x40 but I assure you there is no real mystery involved. The first number simply refers to magnification. For example, if the first number is 10 the object will appear to be 10 times larger than if it were viewed with the naked eye. The second number refers to the diameter of the objective lens. Again, this is the end closest to your subject. The larger the number, the greater the size; generally, bigger is better, but remember that overall size and weight will also increase.

Because of their high magnification and large objective lens, spotting scopes change your experience from that of a casual observer to a close-up participant. If you have the means to pack a scope you’ll be able to check out that trophy before you make the long trek up the mountainside, only to find that it wasn’t really a trophy after all. Serious birders will find that they are able to make highly accurate observations from a much longer distance than with a pair of binoculars.

Don’t be fooled by low cost knock-offs. In terms of quality you really do get what you pay for and there is no substitute for high quality glass and superior craftsmanship. Choose wisely and you’ll have a great outdoors accessory that will last a lifetime; and more.
