April 28 marks 40 years since the U.S. Fish and Wildlife Service listed
the Mexican gray wolf as endangered under the Endangered Species Act.
Yet today, lobos still struggle to survive.
But Colorado can help save them if we move beyond the politics that block successful recovery.
Forty
years ago, lobos were likely extinct in the United States and extremely
rare in Mexico. They were saved from extinction by seven survivors,
which were placed in a captive breeding program. Today, the wild
population numbers 97 in the U.S. and fewer than 25 in Mexico, all of
which suffer from a significant lack of genetic diversity. As a result,
the wild lobo is losing ground again, backsliding toward oblivion due to
political pressure.
In order to survive, thrive and ultimately recover, the lobo needs three things.
First, there is an urgent need for more wolf releases from captivity.
Because all of the lobos alive today are descendants of the original
seven captive wolves, preserving this limited genetic heritage requires
careful management. But ever since the lobo reintroduction program began
in the late 1990s, the U.S. Fish and Wildlife Service has never
released enough wolves from captivity. During the entire Obama
administration, only four new wolves have been released. Of these,
three are dead and one has been returned to captivity.
The lack
of wolf releases over the years has impeded a steady increase in the
lobos' numbers and triggered a continual loss of genetic diversity in
the wild lobo population, resulting in smaller litters, lower pup
survival and a population that is less able to adapt over time to
changing conditions — a recipe for extinction.
The best available
science tells us that in order to beat extinction, lobos need at least
two additional core populations within dispersal distance of the current
population in Arizona and New Mexico. Peer-reviewed, published
scientific research indicates that the best remaining habitats for these
new populations are in the Grand Canyon ecoregion, and in the southern
Rocky Mountains of northern New Mexico and southern Colorado.
Our
second point: Lobos need friendlier politicians in Colorado who are
willing to govern by science, not myth. Gov. John Hickenlooper and the
Parks and Wildlife Commission have actively opposed Mexican gray wolf
releases in Colorado, a position that ignores the important role the
wolves would play in maintaining healthy ecosystems. It also ignores the
findings in Arizona that wolves there did not adversely impact elk
populations or ruin the ranching industry.
Finally, Mexican gray
wolves need a science-based recovery plan to get them out of the jam
they are in and headed toward recovery. The U.S. Fish and Wildlife
Service needs to go where the science leads it and stand firm against
the relentless political pressure from state politicians and wildlife
commissioners who would prefer a plan that keeps Mexican gray wolves out
of needed recovery habitats, leaving the species on the brink of
extinction.
Wolves are a critical component of healthy landscapes
and wildlife populations, which is exactly what Coloradans want. What
we don't need is continued catering to outdated anti-predator interests
at the expense of endangered lobos and a healthy environment. Our
politicians should recognize the will of the majority, and their
decisions should be guided on the best available science.
