The 2013 On-line Update to the Colorado Rare Plant Guide was produced over a two year period though a
cooperative effort involving many individuals and organizations, and is a work in progress.
Critical support to produce species profiles and develop the on-line structure for the 2013
update to the Guide was provided by the Bureau of Land Management and the Colorado Natural Areas
Program. We are especially grateful for the support provided by Carol Dawson (Bureau of Land Management),
and Brian Kurzel (Colorado Natural Areas Program).
Steve Olson, Pike San Isabel Forest Service and Comanche National Grassland contributed his time to
help develop species profiles for species that are known from lands managed by the National Forest Service.
We appreciate the input of our technical reviewers including Brian Kurzel, Carol Dawson, Jenny Neale,
Betsy Neely, Jennifer Ackerfield, Tim Hogan, Steve Popovich, Steve Olson, Gina Glenne, Ellen Mayo,
Al Schneider, Peggy Lyon, Jill Handwerk, Bernadette Kuhn, Pam Smith, and David Anderson.
One of the great strengths of the guide is the depth of information provided through the technical
illustrations and photographs. Individual artists and photographers are recognized throughout the text.
Our partnership with the Rocky Mountain Society of Botanical Artists has been particularly helpful and successful.
