Conservation is critical for the jay, but also for an entire ecosystem, and all the other species that depend upon it. (via undarkmag)
In 2004, the International Union for Conservation of Nature placed the pinyon jay on its Red List as “vulnerable” to extinction. Ita current rate of decline of over 3 percent per year, and a historic loss of “possibly millions” of jays from the 1940s to the 1960s. During roughly the same period, an estimated 3 million acres of piñon-juniper woodland were destroyed to create pasture for livestock.
Johnson said the jays have several adaptations that make them excellent seed dispersers for piñon. Their long bills work like a chisel to crack open the tough piñon shell. Their esophagus expands to store up to 50 nuts, and since they’re highly social, one flock can plant millions of seeds in a fall season, Johnson said. They’re strong fliers with a huge range of several thousand hectares.
For her part, Johnson said some agency management plans “are applied in sort of a generic way,” without taking into account historic wildfire frequency, for example. She noted the scientists’ recommendation for treatments like thinning near human infrastructure, with “less focus on altering the wild areas.”
The petition contains the first estimate of total acreage of piñon-juniper habitat currently treated by the Bureau of Land Management and the U.S. Forest Service in states with pinyon jay populations. The estimate “suggests extensive loss of suitable pinyon jay habitat on federal lands,” with over 440,000 acres impacted, according to the petition.
