Comparison of a species distribution model and a process model from a hierarchical perspective to quantify effects of projected climate change on tree species

Abstract (from http://link.springer.com/article/10.1007%2Fs10980-015-0217-1): Context Tree species distribution and abundance are affected by forces operating across a hierarchy of ecological scales. Process and species distribution models have been developed emphasizing forces at different scales. Understanding model agreement across hierarchical scales provides perspective on prediction uncertainty and ultimately enables policy makers and managers to make better decisions. Objective Our objective was to test the hypothesis that agreement between process and species distribution models varies by hierarchical level. Due to the top-down approach of species distribution models and the bottom-up approach of process...

The Vulnerability of Forests to Climate Change and Wildfire in the Southwestern U.S.

Fire in the western U.S. poses one of the greatest threats to human and ecological communities alike. In fact, fire management is the largest single expenditure of land management funds on federal lands. Now, climate change is altering wildfire patterns. Climate change in the West is creating warmer and drier conditions, resulting in an increase in the amount of dead vegetation available to fuel fires. This project sought to assess the vulnerability of forests in the southwestern U.S. to climate change and wildfire, in order to understand how these ecosystems might become altered as a result. Researchers (a) examined how climate change impacts wildfires in the region, to better understand fire risk; (b) identified...

North River Gameland, North Carolina Myotis septentrionalis Day-roosts

These data contain located day-roosts for the northern long-eared bat (Myotis septentrionalis) at the North River Game Land, North Carolina in May and June of 2019. Data contained include individual bat tracked, date day-roost was found, day-roost unique ID, geographic coordinates of day-roost, tree species of day-roost, diameter breast height (cm) of day-roost, day-roost decay-stage, bat roost height, percent of exfoliating bark on day-roost, surrounding canopy closure and day-roost type (live tree or snag).

Assessing Viability of the Haleakalā Silversword to Uncover the Effects of Climate Change on Hawaiˈi’s High-Elevation Ecosystems

Maui’s threatened Haleakalā silversword forms the foundation of a diverse high-elevation community on Haleakalā, and is an ideal species for assessing how this ecosystem is responding to climate change. The silversword’s striking appearance makes it one of Hawaiʻi’s most recognizable species, and it is one of the main attractions drawing 1-2 million tourists to Haleakalā National Park each year. The plant was once considered a conservation success, when active management led to a population recovery in the early 20th century. Unfortunately, silversword populations are now declining, and climate change – namely decreasing precipitation and increasing temperatures – is thought to be responsible. The goal of this...

Vulnerability Assessment and Adaptation Strategies for Focal Resources of the Sierra Nevada

This project supports a collaborative, multi-stakeholder effort led by the U.S. Forest Service (USFS) to develop a largescale vulnerability assessment and associated adaptation strategies for focal resources of the Sierra Nevada. The purpose of this effort is to provide information and tools for Forest Planning and management (e.g., NEPA analyses, Forest Plan revisions, Climate Scorecard) and other natural resource management (e.g., SWAP) and conservation efforts to prepare for climate change impacts in the Sierra Nevada. Specifically, our objectives are to: (1) assess the vulnerability of focal resources to climate change, (2) use spatial analysis and expert input to prioritize conservation areas or actions, and...
