20.1 Oklahoma BCR 18

All Other Lands in Oklahoma BCR 18

We obtained results for All Other Lands in Oklahoma BCR 18 by compiling and analyzing data from one stratum.

Field technicians completed all planned surveys (100%) in 2025. Technicians conducted 45 point counts within the 4 surveyed grid cells between May 14 and June 12. They detected 40 bird species, including 10 priority species.

Bird Conservancy estimated densities (birds per square kilometer) for 91 species that were detected in any year during which surveys were conducted, 15 of which are priority species. The data yielded robust density estimates (CV < 50%) for 2 species.

Bird Conservancy estimated the proportion of occupied plots throughout All Other Lands in Oklahoma BCR 18 for 91 species that were detected in any year during which surveys were conducted, 15 of which are priority species. The data yielded robust occupancy estimates (CV < 50%) for 7 species.
