Santa Clarita Valley Outdoor Report: Balancing Act

Santa Clarita Valley Outdoor Report: Balancing Act

Dr. Francis Collins, the currect Director of the NIH, is one of my heroes because he is both a top-notch scientist and a Christian.  I like his perspective on dealing with opposing points of view: “One must dig deeply into opposing points of view in order to know whether your own position remains defensible. Iron sharpens iron.”

And when it comes to the issue of reestablishing wolves in California, there are definitely “two opposing points of view”.

One point of view comes from those who make their living working the  land – ranchers and farmers.  My grandparents were dairy farmers and my father was an outdoorsman, so I can readily identify with this perspective.  I see three reasons people are concerned about wolves.

First, wolves can and will kill livestock.  According to this “Wolf Report” from DefendRuralAmerica.com, “Predation on livestock by wildlife is a concern for ranchers and farmers throughout the United States.”  They go on to say, “It is reasonable to expect several outcomes if wolves become established in California.”  And one primary outcome will be that “wolves will kill some livestock.”

Second, wolves can and will kill animals that are also hunted by humans. We know that ungulates such as deer “are favored prey for wolves.”  We also know that, “Prey availability is an important factor affecting wolf distribution and abundance.”  Columbian Black-tailed deer live in Northern California and along the central coast, while here in the south, we see more California Mule deer (including Southern Mule deer).

Third, wolves can and will kill people. There have been two documented cases in North America in the last 100 years, the last one occurring in Alaska in 2010.   If you want to know more about staying safe, here’s a brochure from the Alaska Department of Fish and Game:  “Staying Safe in Wolf Country”.

The second point of view comes from ecologists and environmentalists.  They speak of something known as a “trophic cascade”, which involves the various hierarchical (trophic) levels of a food chain.  “Trophic cascades are powerful indirect interactions that can control entire ecosystems. Trophic cascades occur when predators limit the density and/or behavior of their prey and thereby enhance survival of the next lower trophic level.”

Since wolves have been re-introduced to Yellowstone National Park in 1995, scientists have been studying the ecological effects. According to one website, “We have discovered that an ecological effect called the “trophic cascade” has taken over Yellowstone, with the wolves initiating a more natural ecosystem balance than has been seen in over 65 years.”  This brief video from National Geographic, “How Wolves Change Rivers”, explains it in more detail: “We all know that wolves kill many species of animals…but they give life to many others”.

So what are we to make of all of this?  I have two thoughts to share.  The first is that we have just enough knowledge of the natural world to fool ourselves into thinking we know it all.  The second thought is similar to the first – we have just enough control over the natural world to fool ourselves into thinking we have complete control.  

The choices we make involving the reestablishing of wolves in California will have consequences – some good and some bad, some expected and some unexpected.  My personal choice would be to allow the wolves to reestablish themselves.  But at the same time, I would keep watch for and prepare to deal with the consequences as they arise.
