Living with wildfire in La Plata County, Colorado: 2015 data report Living with wildfire in La Plata County, Colorado: 2015 data report
Residents in the wildland-urban interface (WUI) can play an important role in reducing wildfire’s negative effects by performing wildfire risk mitigation on their property. This report offers insight into the wildfire risk mitigation activities and related considerations, such as attitudes, experiences, and concern about wildfire, for people with homes in select communities in La Plata...

Subterranean invasion by gapped ringed crayfish: Effectiveness of a removal effort and barrier installation Subterranean invasion by gapped ringed crayfish: Effectiveness of a removal effort and barrier installation
Non-native crayfish invasion is a major threat to many stream fauna; however, invasions in subterranean habitats are rarely documented. Our study objectives were to examine demographics and morphological and life-history traits of a gapped ringed crayfish Faxonius neglectus chaenodactylus population that invaded Tumbling Creek Cave and determine the effects of removal on the population...

Post-release breeding of translocated sharp-tailed grouse and an absence of artificial insemination effects Post-release breeding of translocated sharp-tailed grouse and an absence of artificial insemination effects
Context: Translocation has become a widely used method to restore wildlife populations following extirpation. For some species, such as lekking grouse, which breed at traditional mating grounds, reproduction is linked to culturally established geographic locations. Cultural centres are lost upon extirpation, making restoration into otherwise rehabilitated habitats especially challenging...

How and why Upper Colorado River Basin land, water, and fire managers choose to use drought tools (or not) How and why Upper Colorado River Basin land, water, and fire managers choose to use drought tools (or not)
On the Western Slope of Colorado, variable climate and precipitation conditions are typical. Periods of drought—which may be defined by lack of water, high temperatures, low soil moisture, or other indicators—cause a range of impacts across sectors, including water, land, and fire management. The Western Slope’s Upper Colorado River Basin (UCRB) was one of the first pilot areas in which...

Southern Great Plains Rapid Ecoregional Assessment—Volume II. Species and assemblages Southern Great Plains Rapid Ecoregional Assessment—Volume II. Species and assemblages
The Southern Great Plains Rapid Ecoregional Assessment was conducted in partnership with the Bureau of Land Management (BLM) and the Great Plains Landscape Conservation Cooperative. The overall goal of the Rapid Ecoregional Assessments (REAs) is to compile and synthesize regional datasets to facilitate evaluation of the cumulative effects of change agents on priority ecological...

Vegetative and geomorphic complexity at tributary junctions on the Colorado and Dolores Rivers: a blueprint for riparian restoration Vegetative and geomorphic complexity at tributary junctions on the Colorado and Dolores Rivers: a blueprint for riparian restoration
Context Habitat complexity in rivers is linked to dynamic fluvial conditions acting at various spatial scales. On regulated rivers in the western United States, tributaries are regions of high energy and disturbance, providing important resource inputs for riparian ecosystems. Objectives This study investigated spatial patterns and extents of tributary influence on riparian habitat...

Communicating information on nature-related topics: Preferred information channels and trust in sources Communicating information on nature-related topics: Preferred information channels and trust in sources
How information is communicated influences the public’s environmental perceptions and behaviors. Information channels and sources both play an important role in the dissemination of information. Trust in a source is often used as a proxy for whether a particular piece of information is credible. To determine preferences for information channels and trust in various sources for...

An experimental comparison of composite and grab sampling of stream water for metagenetic analysis of environmental DNA An experimental comparison of composite and grab sampling of stream water for metagenetic analysis of environmental DNA
Use of environmental DNA (eDNA) to assess distributions of aquatic and semi-aquatic macroorganisms is promising, but sampling schemes may need to be tailored to specific objectives. Given the potentially high variance in aquatic eDNA among replicate grab samples, compositing smaller water volumes collected over a period of time may be more effective for some applications. In this study...

Twenty-nine years of population dynamics in a small-bodied montane amphibian Twenty-nine years of population dynamics in a small-bodied montane amphibian
Identifying population declines before they reach crisis proportions is imperative given the current global decline in vertebrate fauna and associated challenges and expense of recovery. Understanding life histories and how the environment influences demography are critical aspects of this challenge, as is determining the biological relevance of covariates that are best supported by the...

Evaluating riparian vegetation change in canyon-bound reaches of the Colorado River using spatially extensive matched photo sets Evaluating riparian vegetation change in canyon-bound reaches of the Colorado River using spatially extensive matched photo sets
Much of what we know about the functional ecology of aquatic and riparian ecosystems comes from work on regulated rivers (Johnson et al. 2012). What little we know about unregulated conditions on many of our larger rivers is often inferred from recollections of individuals, personal diaries, notes, maps, and collections from early scientific surveys (Webb et al. 2007) and from repeat...

Biophysical assessment for indemnity selection of Federal Lands in Colorado Biophysical assessment for indemnity selection of Federal Lands in Colorado
Information on the biophysical features of Federal lands identified as suitable for transfer to the State of Colorado was requested by the Bureau of Land Management (BLM). This information is intended for use in conducting an Environmental Assessment prior to the transfer of ownership (conveyance) to the State. The Colorado State Land Board filed a selective application to obtain public...

Evaluating potential distribution of high-risk aquatic invasive species in the water garden and aquarium trade at a global scale based on current established populations Evaluating potential distribution of high-risk aquatic invasive species in the water garden and aquarium trade at a global scale based on current established populations
Aquatic non‐native invasive species are commonly traded in the worldwide water garden and aquarium markets, and some of these species pose major threats to the economy, the environment, and human health. Understanding the potential suitable habitat for these species at a global scale and at regional scales can inform risk assessments and predict future potential establishment. Typically...
