A quantitative global review of species population monitoring

open access: yesConservation Biology, Volume 36, Issue 1, February 2022., 2022
Abstract Species monitoring, defined here as the repeated, systematic collection of data to detect long‐term changes in the populations of wild species, is a vital component of conservation practice and policy. We created a database of nearly 1200 schemes, ranging in start date from 1800 to 2018, to review spatial, temporal, taxonomic, and ...
