Important links for Black bear, Rafinesque's big-eared bat, and timber rattlesnake This data set contains links that are important to each species' habitat network. Those important links are scored based on the percent currently under protection status, projected change in climate suitability by the middle of the 21st century, and projected change in percent urbanized by the middle of the 21st century. Important links were identified from all links in the networks of each species based on their Integral Index of Connectivity (dIIC). Any links with dIIC scores > 0.9 or which connected to nodes with dIIC > 0.9 were retained here as "important" links.

LRD represents the degree to which habitat availability limits species movement. LRD decreases as habitat availability increases and increases as habitat availability decreases. This data set includes a range of LRD thresholds to represent species with different dispersal abilities and responses to landscape structure. A threshold indicates the highest LRD that still allows dispersal by a particular group of species. LRD thresholds are included in the data set, with low values representing connectivity...

Scenario A1B emphasizes economic growth with a global orientation and scenario B2 focuses on environmental sustainability with a regional view. Our study area included counties within the southern Great Plains ecoregion in Oklahoma, Texas, and New Mexico. We calculated changes in landscape connectivity (dECA) between 2011 and 2050 for different species groups and landscape scenarios. We also calculated changes in habitat suitability (dA). We assessed the degree to which changes in landscape connectivity were influenced by changes in grassland...

Wildlife and Plants, dispersal (organisms), habitat fragmentation, Fewer tags Unburned areas within fire perimeters across the Inland Northwestern USA from 1984 to 2014 We established a Landsat-derived geospatial database of unburned islands within 2,298 fires across the Inland Northwestern US (including eastern Washington, eastern Oregon, and Idaho) from 1984-2014. The detection of unburned areas within these fires is based upon a classification tree approach that uses two pre- and post-fire Landsat image pairs (see Meddens et al 2016 for details). The data set consist of unburned patches within each fire that are two pixels or larger. This database will be useful for identifying fire refugia, seed sources, and can be used as an overall metric of fire impacts across the northwestern US. (Meddens, A.J., Kolden, C.A., & Lutz, J.A.

Wildlife and Plants, dispersal (organisms), habitat fragmentation, Fewer tags Reducing Wildfire Risk While Maintaining Critical Monarch Habitat Along the California Coast The California Coast has hundreds of tree groves where dual management practices aim to reduce the risk of fire and to conserve habitat for overwintering monarch butterflies. As the climate changes, longer high-intensity droughts can increase mortality and/or limb loss in grove trees which causes an accumulation of fire-prone fuels. Moreover, these trees provide the critical habitat for overwintering monarch butterflies. Every year only certain trees in certain groves accumulate clusters of thousands of monarch butterflies. Should trees die or important roosting branches collapse, monarchs may not return in the future. The overall goal of this project is to understand how the dual management goals of fire management...

For each species, we mapped important habitat connections between core patches of habitat using three different modeling approaches (Connectivity Analysis Toolkit (CAT), Circuitscape, and Linkage Mapper) that incorporated three types of resistance layers (expert opinion, niche modeling, and empirical data for the black bear only). The result was 21 sets of important connections,...

Severe fires combined with persistent drought and invasive species can slow or prevent the recovery of burned forests and shrublands to their pre-fire states, resulting in ecological, economic, and cultural losses. Forests may be converted to shrub fields or grasslands, and shrublands may be replaced by invasive grasses. While shrublands and grasslands can be important components of these ecosystems, there is growing concern about the increased extent of these vegetation types on the landscape. Despite the severe post-fire vegetation transformations, little is known about where, when,...

This analysis involved several steps. First, time-series climate data were compiled and plotted to identify drought periods. Similarly, time-series data representing insect outbreaks were compiled and plotted to identify trends in insect mortality. The study area was classified into forest canopy types using existing...

They are also vulnerable to climate change. In particular, changes in winter climate (warmer temperatures and fewer freeze events) may transform coastal wetlands in the northern Gulf of Mexico, as mangrove forests are expected to expand their range and replace salt marshes. The objective of this research was to evaluate the ecological implications of mangrove forest migration and salt marsh displacement. As part of this project, researchers identified important thresholds for ecosystem changes and highlighted coastal areas in the southeastern U.S. (e.g., Texas, Louisiana,...
