Bobolink (Dolichonyx Oryzivorus) & Eastern Meadowlark (Sturnella Magna) in Ontario

Résumé du livre

"The long-term recovery goal is to maintain stable, self-sustaining populations of Bobolinks and Eastern Meadowlarks in Ontario, and in so doing contribute to the conservation of the guild of grassland birds. In the short term (over the 10-year period from 2013-2023), the goal is to slow the annual rate of population decline for both species to an average of no more than 1 percent per year (i.e., no more than 10% over 10 years). Achieving population stability at roughly 90 percent of the present-day population size is the long-term goal thereafter."--Executive summary.
