In 2005, thanks to the help of two great volunteers, John and Donna Woods, the park has added lichens to the growing set of park species checklists available on our website. This was compiled from several sources- personal communications from University of Colorado- Boulder emeritus professor William Weber, a list of lichens used by air quality researcher James Bennett, and a list of lichens donated to the park's museum collection by Dr. Robert Egan's Rocky Mountain Nature Association Seminar lichen class for 2004. A special thanks also goes to Connie and Stan Heginbotham for providing so many outstanding photos to illustrate this list.
