This disease has caused the death of millions of bats in the East and bat biologists in the West are struggling to understand what this means for western bat populations. To gain a better understanding of population dynamics of little brown bats in Colorado, CNHP and Colorado Parks and Wildlife have partnered to monitor several large maternity colonies in northern Colorado. CNHP has marked female and young bats at two ranches, The Nature Conservancy\u2019s Carpenter Ranch and The Yampa Valley Land Trust\u2019s Rehder Ranch, and are using PIT-tag reading antennas to document when and how many bats return. These data will be used in mark-recapture analyses to assess survival and population persistence.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/sites.warnercnr.colostate.edu\/rschorr\/wp-content\/uploads\/sites\/139\/2020\/01\/gaf_026138-1.jpg\" alt=\"\" class=\"wp-image-135\" srcset=\"https:\/\/sites.warnercnr.colostate.edu\/rschorr\/wp-content\/uploads\/sites\/139\/2020\/01\/gaf_026138-1.jpg 1024w, https:\/\/sites.warnercnr.colostate.edu\/rschorr\/wp-content\/uploads\/sites\/139\/2020\/01\/gaf_026138-1-300x200.jpg 300w, https:\/\/sites.warnercnr.colostate.edu\/rschorr\/wp-content\/uploads\/sites\/139\/2020\/01\/gaf_026138-1-768x512.jpg 768w, https:\/\/sites.warnercnr.colostate.edu\/rschorr\/wp-content\/uploads\/sites\/139\/2020\/01\/gaf_026138-1-624x416.jpg 624w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Since 2014, we have marked ~2,000 little brown bats, with some individuals spending a majority of their time at one roost.
