Did you know that freshwater mollusks are becoming one of the most endangered group of animals in North America? Wildlife professionals are collecting information on Colorado’s mollusk population to determine if the species here are endangered. The Colorado Division of Wildlife has released “A Field Guide to the Freshwater Mollusks of Colorado” to aid field biologists and other concerned citizens in the identification and inventory of mollusk populations in the state. The book is available online, and can also be checked out from the State Publications Library, or any of our depository libraries across the state.
