Plant Check List for North Hogback Open Space, City of Golden, Jefferson County, Colorado
Edited by Tom Schweich
This list is assembled from personal collections, herbarium vouchers, and published lists, that were available at the time this list was prepared. There may be additional species of plants in this area that were unknown or undocumented at the time this list was prepared. For California, much of the data is provided by the participants of the Consortium of California Herbaria (http://ucjeps.berkeley.edu/consortium/). For Colorado, much of the data is provided by the Southwest Environmental Information Network, which web site is found at (http://swbiodiversity.org). See their respective websites for copyright information and recommended citation formats. For a complete list of Locations included in this Area List, see the Locations Included section, below. This page is highly summarized. For detail about the distribution of plants, please see: Detailed Area List for North Hogback Open Space (City of Golden), Jefferson County, United States.
Area Description: The south end of Dakota Ridge and the adjacent Cressman Gulch is in the very northern part of Golden. Several names have been applied to this open space, including Dakota Ridge. The name was applied by Van Horn (1957) in Bedrock Geology of the Golden Quadrangle. “Dakota Ridge” is also sometimes applied to the corresponding hogback south of Golden. However, through the Open Space Master Planning process, the name North Hogback Open Space is currently proposed for this hogback.
