This dataset depicts Lynx (Lynx canadensis) habitat in the Northern Appalachians predicted using the spatially explicit population model PATCH under the population cycling only in Gaspe (core area) scenario (B1; Carroll 2007). This dataset represents one of several scenarios testing the interacting effects of population cycling, trapping, territory size, and climate change on lynx populations. Static habitat suitability models for lynx were fed through PATCH to predict source and sink habitat areas across the landscape. The static models for lynx were created based on a logistic regression model of reported lynx locations against the proportion of the landscape in deciduous forest cover and annual snowfall.

This dataset shows simulated fisher territory occupancy for a study area the southern Sierra Nevada range from the Extreme Fire Regime plus No Treatment scenario (Scheller and others 2008). Simulations were conducted using the spatially dynamic population model PATCH coupled to the forest succession and disturbance model LANDIS-II. Fisher occupancy is represented as the average number of females per 860 hectare hexagon. Habitat quality was derived from LANDIS-II simulated vegetation dynamics and was used to drive spatially-explicit demographic dynamics in PATCH> The baseline fire regime is derived from the previous 20 years of fire data. The extreme fire regime is a purely hypothetical fire regime intended to produce...

This dataset depicts Wolf (Canis lupus) habitat in the Northern Appalachians predicted using the spatially explicit population model PATCH under the current habitat effectiveness plus moderate US mortality plus low Canadian mortality scenario (Carroll 2003). This dataset represents one of several scenarios testing the effects of habitat effectiveness and mortality rates on wolf populations. Static habitat suitability models for wolf were fed through PATCH to predict source and sink habitat areas across the landscape. The static models for wolf were created based on current and projected habitat effectiveness, which were based in part on road density and human population density. Wolf fecundity rates were based on...
Conserving migratory or wide-ranging species presents considerable challenges, as these individuals move across disparate jurisdictions often crossing international borders among crucial stages of their annual cycle. Within North America, Migratory Bird Joint Ventures (JVs) have established successful partnerships to coordinate the planning and delivery of conservation actions within key regions to benefit migratory bird populations. However, the extent to which local conservation actions influence regional demographics and in turn affect continental population dynamics remains poorly understood. Maximizing efficient use of limited resources to conserve habitats for wide-ranging species has motivated a critical...

Executive Summary: Riparian ecosystems are vital components of the semi-arid landscape because woody riparian plants provide resources that are absent in adjacent vegetation types. Historically, flood played a key role in shaping the composition and structure of riparian forests. In recent decades, however, the frequency and magnitude of floods has decreased and the timing of peak discharge has been altered. In addition, wildfire has increased in importance as an agent of disturbance along many streams. We initiated this study to increase our understanding of fire, flood, and drought processes at our Middle Rio Grande study sites and develop tools that managers of other systems can use to project the response of...

This dataset represents one of several scenarios testing the interacting effects of trapping, timber harvest, habitat restoration, and climate change on marten populations. Static habitat suitability models for marten were fed through PATCH to predict source and sink habitat areas across the landscape. The static models for marten were created based on annual snowfall and percentage of older conifer and mixed forest. Demographic parameters were obtained from the literature and from...

Rivers in the SRLCC differ from one another in flow characteristics, levels of regulation, and vulnerability to wildfire; characteristics that will be influenced by climate change (Seager et al. 2007, Mortiz et al. 2012). An understanding of how changes in streamflow and wildfire frequency will affect structure of live and dead woody vegetation is needed to for managers assess the vulnerability of riparian obligate species to climate change. We are developing stochastic transition models for cottonwood trees and snags along the Middle Rio Grande by modifying Lytle and Merritts (2004) stage-structured cottonwood population model. By incorporating influences of flood and wildfire into stage transition rates, we can...

Perennial streams in the Desert LCC support riparian trees such as cottonwood (Populus spp) and box elder (Acer negundo) that are critical components of habitat for riparian obligate birds and other wildlife species (Webb et al. 2007). Trees, snags, and fallen woody debris provide nesting and foraging sites for a variety of riparian animals (Bateman et al. 2008, Smith et al. 2012). Riparian trees require occasional floods to create space suitable for germination and are dependent on accessible groundwater for growth and survival (Lytle and Merritt 2004). Studies along the Middle Rio Grande in New Mexico have shown that rates of woody debris accumulation are also influenced by hydrology because floods physically...
