P., author; Fink, J., author; Handwerk, J., author; Doyle, G., author; Panjabi, S. S., author; Colorado Natural Heritage Program, publisherSpecies distribution models for 81 of the 117 plant species listed in the Rare Plant Addendum of the Colorado State Wildlife Action Plan (CPW 2015) were created using information on known locations and species habitat requirements. These distribution models have been included in the conservation data sharing platform, the Colorado Conservation Data Explorer (CODEX), to help conserve and protect these Plants of Greatest Conservation Need (PGCN) through environmental review and conservation planning. Expert review of species distribution models was solicited from regional botanists; Forty-six individual botanists reviewed a total of 75 species distribution models, with a total of 113 reviews. Over 80% of reviews concluded that the model in question was in the "Reasonable" or higher level of overall correctness. Also included in this report are results of a pilot project to predict changes in suitable habitat under two potential future climate scenarios for Astragalus microcymbus, Astragalus osterhoutii, Draba smithii, Eutrema penlandii, Frasera coloradensis and Ipomopsis polyantha. The modeling work of this project amplifies our knowledge, building upon decades of field work preserved in CNHP's database, and advances our understanding of species habitat.

This assessment will be used by Facilities Management to self-report on the Biodiversity component of the Operations category in the STARS (Sustainability, Tracking, Assessment, & Ratings System) report. This report assesses endangered and vulnerable species (including migratory species) on CSU-owned and managed lands and areas of biodiversity importance on CSU-owned and managed lands. An additional aim of this project was to include students in the geospatial analysis, research, and field data collection efforts, thereby lowering project costs and providing mentorship and experience to the students. Biodiversity was assessed through a geospatial environmental review of the properties which includes documented and potential occurrences of regulatory species and other species of concern within the property and a 1-mile buffer, assessment of the conservation areas adjacent to the property and within a buffer, and the diversity and acreage of wetlands and other ecosystem types. The conservation value of each property, based on a Return-on-Investment report, is presented. Geospatial data area used to evaluate climate resiliency and landscape disturbance. Further research into species on the largest and most well-studied properties is presented, along with results of field work. Colorado State University holds 32 individual properties, spanning 14 counties across Colorado, covering a total of 3,943 hectares. Properties held by CSU had 303 documented occurrences of regulatory species and other species of concern within 1 mile returned in the environmental review; additionally, potential habitat was returned for another 2210 regulatory and other species of concern from a combination of range maps, general precision CNHP element occurrence records, and models. Through the many metrics of biodiversity assessed, several properties stood out; these included the Eastern Colorado Research Center, the Mountain Campus, Foothills, Horsetooth, and the Environmental Learning Center. At the Eastern Colorado Research Center, a combination of research field work recorded 187 species as visual observations and/or within a modeled area. At the Mountain Campus, student research and field work recorded a total of 1,044 species as visual observations and/or within a modeled area, with 754 Animalia species, 273 Plantae species and 17 Fungi species. Along with providing information on the biodiversity on the CSU lands, this project provided educational value to CSU students and facilitated the creation of a storymap to showcase the biodiversity of CSU lands to the public and stakeholders. The biodiversity assessment suggests several actions which could be taken to protect, enhance, or restore the biodiversity found on CSU lands and identified properties with possible conservation gains through enhancement and restoration.
