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 South Table Mountain Open Space (City of Golden), Jefferson County, United States.
Area Description: South Table Mountain Open Space is a small triangular area located on the western slope of South Table Mountain, organized mostly around the Lubahn Trail and connections to Jefferson County Parks and Open Space’s Olivine Trail. The open space features volcanic rock formations, scenic overlooks, and educational geological features such as Castle Rock and the K-Pg boundary.
Data Quality: There are actually very few collections in the City of Golden South Table Mountain Open space. Most of the data reported in the list below are my observations. Many of the collections on South Table Mountain did not distinguish between City of Golden lands and Jefferson County Lands, or state lands.
