With a light layer of snow covering the ground a Mule Deer doe gives us the once over before moving back to foraging. Feasting on what were to be the last remain green grasses of Autumn as the snow gently fell. The next day a cold snap set in flipping the switch that turned all things all to brown.

Hope your weekend is a great one.

The importance of wilderness

“Wilderness areas act as a buffer against species loss, as the extinction risk for species within wilderness communities is—on average—less than half that of species in non-wilderness communities.” 1

A recent study published in the Journal Nature titled “Wilderness Areas Half The Extinction Risk of Terrestrial Biodiversity” mapped several locations around the world where maintaining wilderness areas should be a priority. The first statement the authors make in the abstract in this paper really hit the nail on the head for me.

“Reducing the rate of global biodiversity loss is a major challenge facing humanity, as the consequences of biological annihilation would be irreversible for humankind. 1

In this single sentence the authors make clear that the steady march of human activity, as currently, conducted could potential be catastrophic to all life on earth.

“Wilderness areas act as a buffer against species loss, as the extinction risk for species within wilderness communities is—on average—less than half that of species in non-wilderness communities.” 1

The paper points to several locations on the plant especially important to protect yet the authors also state that all wilderness areas have intrinsic conservation value thus we can all play a role by supporting local conservation efforts of wilderness area near to each of us. Below we showcase a few wilderness area we have recently spent time in. They are both beautiful as well as safe havens for biodiversity.

On the talus slope

Pika_201934

I never get disappointed when I hear the little chirp of a Pika moving about on the talus slopes. Always spotting us before we spot them. usually sitting still and looking out into their environment then scurrying off to collect plants for winter larder. The Pika is yet another species threaten by climate change and the focus of this short video in Smithsonian Magazine.

It is encouraging that some Pika may be showing behavior adaptation to a loss of habitat resulting from climate change but as the authors of a recent study concludes “while many species have a clear capacity to modulate behavior in relation to variations in climate parameters,much remains to be learned about the trade-offs, fitness implications, and limitations of behavioral flexibility in the context of novel climate dynamics.”

I sure hope these little guys are able to adapt to the new reality imposed upon them by our species. A walk on the talus slopes without them would be a lonely walk indeed.

Three Billion Birds: follow-up.

Fall_meadowlark_1

We recently linked to a study finding that over 3 billion birds have been lost from the ecosystem in North America as well as a study indicating that perhaps 66% of North American Birds are threatened with extinction resulting form anthropogenic climate change.

For those who are interested we just received an email informing us of an online presentation this Monday evening Nov, 4th at 7pm EST by Dr. Ken Rosenberg of the Cornell Laboratory of Orinthology titled “3 Billion Birds Gone: The Bird Crisis and What We Can Do About It“. Importantly it looks like this presentation will focus on the broader implication of the results of these findings beyond birds.

Looks to be an interesting presentation.
