| Popis: | The City of Boulder Mountain Park sits in the eastern foothills of the northern Front Range of Colorado. Approximately 7000 acres (2800 ha) in extent, the study area is characterized by a foothills and montane vegetation and flora, predominantly of western North American distribution. Situated at the interface of the Great Plains and the Rocky Mountains, the flora of the Mountain Park is distinguished by a wealth of species with eastern woodland affinities, as well as a number of southern Rocky Mountain species endemic to the Front Range. Six hundred and ninety-eight (698) species of vascular plants in 426 genera and 100 families are documented in this survey. Twenty (20) of the plants are listed as Species of Special Concern by the Colorado Natural Heritage Program, with an additional 26 listed as sensitive by the City of Boulder Open Space and Mountain Parks Department (OSMP). Introduced non-native species constitute 21% of the flora (147 species), a figure that exaggerates their ecological role in the Park; less than a dozen introduced species are of serious concern in their impact upon native diversity. The Mountain Park is viewed by many as the crown jewel of the City’s OSMP system, and serves as a model for public land management across other open spaces in urban areas nationwide. These forested foothills, with their prominent relief and associated diversity of habitats, serve as one of the last low-elevation nature refuges along the Colorado Front Range. With the increasing urbanization of the region and the loss of biological diversity worldwide, the wisdom of the Boulder community in protecting this landscape is becoming ever more apparent. This report presents a thoroughly revised checklist of the flora of the Boulder Mountain Parks since the area was last inventoried in 1993. |
