There is no information available about a nonprofit organization named "Community of Condon for the Preservation of Swan Valley" with the EIN 920718257. Therefore, I cannot write a Wikipedia-style article about this organization.

If you are interested in organizations working in the Swan Valley area, you might consider looking into Swan Valley Connections or the Vital Ground Foundation, both of which are involved in conservation efforts in the region[1][2].
