Legislative Updates

Colorado Coalition of Land Trusts - Updates at www.cclt.org on legislation regarding the use of conservation easements in Colorado.

Local Government Best Practices and Certification

The Holding Conservation Easements: A Local Government Best Practices Handbook is complete! The goal of this Handbook is to provide peer-reviewed guidance to local governments on the acceptance and stewardship of conservation easements whether the local government has an established program or is just exploring the idea of holding conservation easements. The working group presented the handbook at the 2009 COSA conference and took final comments and suggestions. Hard copies are available or you can view it online [pdf].

The Colorado Division of Real Estate has released the application for local government Certification. For questions about the certification process contact Jordan Beezley at jordan.beezley@dora.state.co.us. Local governments who want to accept conservation easements that have a tax credit component must become certified by December 31, 2010.


Blue Gramas - The new Blue Grama Awards will recognize outstanding management and programs offered by Colorado open space organizations.
