New sage grouse data 'alarming,' state biologist says
The latest data on greater sage grouse in Wyoming indicate an alarming likelihood of populations regressing to a 1996 nadir, the states top grouse biologist said Thursday.
The preliminary data from hunter submitted sage grouse wings during the 2021 shooting season show a ratio of 0.8 chicks per hen. Thats below whats needed to stabilize the shrinking population, Wyoming Game and Fish sagebrush and sage grouse biologist Leslie Schreiber said Thursday.
Zero point eight chicks per hen is associated with a declining population because 1.5 chicks per hen is needed for population stability, Schreiber said.
The wing data suggests that another key population metric anticipated in 2022 a count of strutting males on breeding-ground leks also will be lower, she said.
