Libraries, 2014-12) Fink, Michelle, author; Decker, Karin, author; Colorado Natural Heritage Program, publisherDuring the revision of Colorado's current SWAP, the Colorado Natural Heritage Program (CNHP), Colorado Parks and Wildlife (CPW), North Central Climate Science Center and U.S. Geological Service Fort Collins Research Center collaborated to produce climate change vulnerability assessments for high priority wildlife habitats in the state. Our objectives were to: 1. Evaluate exposure and sensitivity of priority habitats by identifying the degree of climate change expected between current and future conditions for climate factors believed to influence the distribution of the habitat. 2. Evaluate adaptive capacity of each habitat by assessing factors that affect the resilience of the habitat to change in landscape condition, invasive or problematic native species presence, dynamic process alteration between past and current conditions, and the characteristic bioclimatic envelope of the habitat. 3. Produce summary vulnerability ratings for priority habitats.Item Open Access Comprehensive statewide wetlands classification and characterization: wetland plant associations of Colorado: preliminary report 1999-2001(Colorado State University.

Libraries, 2007) Decker, Karin, author; Panjabi, Susan Spackman, author; Colorado Natural Heritage Program, publisherThe purpose of this project is to develop a Strategic Plan for the control of invasive plant species on military installations along the Front Range of the Rocky Mountains in Colorado and Wyoming. The project rolls up goals and objectives from individual installation invasive species control plans and prioritizes control efforts by species and specific infestations in the context of protecting significant natural resources. The primary goal of this strategy is to identify the most critical 10-15 weed infestations in need of control at the Front Range military installations and to facilitate developing a regional strategy to encourage an efficient approach to natural resource and noxious weed management involving sharing knowledge, tools, and expertise across the Front Range region. The strategic plan is coordinated with the counties and states where the installations occur. For the purposes of this report, we focus primarily on invasive plant species that are legally designated "noxious weeds". "Noxious weeds" are non-native plant species which have been designated for mandatory control by local, state, or federal government because of the harm that they are capable of inflicting upon the resources and values of society (Lane 2001). We also provide information about other non-native plants found on the installations as available.Item Open Access Great Sand Dunes National Monument and Preserve 2003 vascular plant inventory(Colorado State University.

Libraries, 2013-04) Smith, Gabrielle, author; Handwerk, Jill, author; Fink, Michelle, author; Decker, Karin, author; Colorado Natural Heritage Program, publisherSpecies distribution modeling is one of many tools available to assist managers in understanding the potential distribution of rare and endemic species when regulating and prioritizing different land-use scenarios. Developing a predictive model of the distribution of a particular species can involve several different techniques, and be reported under a variety of names. All such models, however, are based on the ecological principle that the presence of a species on the landscape is controlled by a variety of biotic and abiotic factors, in the context of biogeographic and evolutionary history. Because we rarely, if ever, have complete and accurate knowledge of these factors and history, we can only seek to predict or discover suitable habitat by using characteristics of known occurrences of the taxon in question. The modeling process is further constrained by our inability to measure habitat characteristics accurately on a continuous spatial scale. As a result, modeling factors are usually an approximation of the environmental factors that control species distribution, using available data that is probably only a surrogate for the actual controlling factors. In the context of our study, species distribution modeling is a process that uses a sample of a real distribution (known locations or element occurrences) to build a model (estimate) of suitable environmental conditions (and, by implication, unsuitable conditions), and map that model across a study area. In this study we used an iterative modeling approach to investigate the potential distribution of two rare species: Physaria (Lesquerella) congesta and Physaria obcordata.Item Open Access Kobresia simpliciuscula (Wahlenberg) Mackenzie (simple bog sedge): a technical conservation assessment(Colorado State University.
