With 5,500 acres many scientists feel Selah is a functioning ecosystem. Selah contains all the components of an ecosystem from tiny microbes in the water to apex predators like Mountain Lions. The biodiversity at Selah is species rich and diverse in every facet. From 6 identified species of cacti to 213 species of birds.

Our goal is to document every biological organism that occurs on site. We know it’s ambitious and time consuming but using staff, volunteers, universities, and our school visitors we have a good start and make continued progress each day. We will house our own museum collection in our research and education building.
