The Colorado Spider Survey is a biotic inventory project assessing the biodiversity of spiders and other arachnids in Colorado and the Rocky Mountain and Great Plains ecoregion. The project has been ongoing since 1999. If you are interested in getting involved in this project, you can take a training workshop or a Spider Biology class. To get notifications about upcoming workshops or classes, please send your e-mail address and other contact information to [email protected]. You will be added to an "arachnophile" distribution list and will get schedules of upcoming training events.

Data from the project is accessible from the CSS webpage and via GBIF.

Data from the project can also be accessed at http://www.scanbugs.org or a direct link to collections data at the SCAN collections search site
