 Golden, Colorado sits in a valley formed by erosion along the Golden fault, the geotectonic boundary between the North American Cordillera and the Great Plains. Somewhat like Mono Lake, for which I have also prepared a checklist flora, it sits at a boundary, or perhaps ecotone. Things are always more interesting at the boundaries. I started this project when I realized no such list had been prepared for my newly adopted city. I hope you find this checklist flora helpful. Please write to me if you have questions or comments.

Recognized Ecological Systems

 

Ecological Systems Recognized by the Colorado Natural Heritage System

Literature Cited:
- Colorado Natural Heritage Program, 2005.  

Ecological systems are dynamic assemblages or complexes of plant and/or animal communities that 1) occur together on the landscape; 2) are tied together by similar ecological processes, underlying abiotic environmental factors or gradients; and 3) form a readily identifiable unit on the ground. These systems provide a coarser level unit than plant associations and alliances as defined under the International Vegetation Classification standard, and are more easily identified on the ground.

The descriptions and summarized viability guidelines presented here are intended to serve as a tool for conservation and management planning by providing a context for conservation and management (i.e., what systems do we have in Colorado), and by providing easy access to ranking and evaluation criteria for key ecological attributes of each system (i.e., what is the condition of our systems).

System descriptions and viability guidelines are based on materials compiled by NatureServe or developed by the Colorado Natural Heritage Program. Funding for the development of these documents was provided in part by the Bureau of Land Management, The Nature Conservancy, and the USDA Forest Service (CNHP, 2005).

Southwest Regional Gap Analysis Project (SWReGAP)

Literature Cited:
- Rondeau, R., K. Decker, J. Handwerk, J. Siemers, L. Grunau, and C. Pague, 2011.  

The Southwest Regional Gap Analysis Project (SWReGAP) was a mapping and assessment of biodiversity for the five-state region encompassing Arizona, Colorado, Nevada, New Mexico, and Utah. The area comprises approximately 150 million hectares (560,000 square miles) representing 1/5 the coterminous United States. The primary objective of the project was to use a coordinated approach to create detailed, seamless maps of the land cover, habitat for native terrestrial vertebrate species, land stewardship, and management status for the Southwest region. This information was analyzed to identify animal species habitats and natural land cover types that are underrepresented on land managed for their long term conservation. SWReGAP was a multi-institutional effort with scientists based in all five southwest states.

USNVC -- United States National Vegetation Classification

  http://usnvc.org/
  The U.S. National Vegetation Classification is supported by a formal partnership between the federal agencies, the Ecological Society of America (ESA), and NatureServe, working through the Federal Geographic Data Committee (FGDC) Vegetation Subcommittee. Primary signators include the U.S. Forest Service (which chairs the subcommittee), ESA, NatureServe, and the U.S. Geological Survey Core Science Systems (USGS/CSS). Together we are committed to supporting the implementation and maintenance of the National Vegetation Classification (NVC) Standard (FGDC 2008).
  The overall objective of the Vegetation and Information Standards is to support the use of a consistent national vegetation classification system (NVCS) to produce uniform statistics in vegetation resources from vegetation cover data at the national level. It is important that, as agencies map or inventory vegetated Earth cover, they collect enough data accurately and precisely to translate it for national reporting, aggregation, and comparisons. Adoption of the Vegetation Classification and Information Standards in subsequent development and application of vegetation mapping schemes will facilitate the compilation of regional and national summaries. In turn, the consistent collection of such information will eventually support the detailed, quantitative, geo-referenced basis for vegetation cover modeling, mapping, and analysis at the field level.

Populus angustifolia E. James

James provided a validating diagnosis: "The long leaved cotton-wood is found intermixed with the common cotton-wood, resembling in size and general aspect. Its leaves are long and narrow, its trunk smoother, and its branches more slender and flexile than those of Populus anuglata. Some of its fruits was fortunately still remaining "

Lupinus argenteus Pursh

  Harrington (1954) and Ackerfield (2015) neither use keel decoration as a key character nor do they describe the decoration of the keel. California floras, e.g., Munz (1965) and Baldwin (2012), use a ciliate keel, as a key character to identify L. argenteus. Welch, et al. (1993) note that the keel can be glabrous or variously ciliate.
