While meadows cover less than one percent of the Sierra Nevada, these ecosystems are of high ecological importance given their role in carbon and nitrogen storage, mediation of surface water flows, groundwater recharge, sediment filtration, and as refugia for numerous species. Understanding how – and where – to conserve and restore meadow ecosystems is a critical management question facing US Forest Service (USFS) and other land managers in the Sierra Nevada. The information and tools generated from this project are intended to significantly increase understanding of meadow responses to climate, associated changes in hydrology, and to develop conservation and restoration priorities that are strongly aligned with...

FY2014Avoiding cheatgrass dominance following tree-reduction treatments on woodland-encroached sagebrush communities is a priority for managers in the Great Basin. Perennial herbaceous and weedy annual cover have been related to site resilience after treatment and associated with soil climate regimes and site physical characteristics. Additional investigation of site characteristics associated with vegetation response will allow us to better decide which sites to treat and whether seeding is needed or not in conjunction with tree reduction treatments. Site-level planning also requires an understanding of how climate change may influence vegetation response to treatments. We propose to associate site-measured soil...

Dozens of species of landbirds, such as warblers, hummingbirds, and orioles, migrate through the Northeastern United States from their summer breeding grounds in the U.S. and Canada to their nonbreeding grounds as far south as South America. During the migration period, birds must find habitat where they can stop, rest and replenish their energy reserves. Conservation efforts are increasingly focused on identifying stopover sites that are important for sustaining migratory landbird populations. This project builds upon prior work by the University of Delaware and USGS to use weather surveillance data and field surveys to map and predict important migratory bird stopover sites.This project was co-funded by through...
The Highstead Foundation worked with partners to deliver, disseminate, and communicate North Atlantic LCC science products to help advance the knowledge base, strategic conservation planning, and on-the-ground conservation success of regional conservation partnerships (RCPs). There are 39 RCPs in New England (and eastern New York) covering more than 60 percent of the landscape, working across town and even state boundaries to achieve conservation that is both locally grounded and regionally significant. Each RCP is composed of multiple land trusts, community leaders, agencies, and conservation groups. Highstead, in partnership with the GIS office of Harvard Forest, Harvard University, provided technical assistance...
This project built off a first phase of work funded by Northeast states through the Regional Conservation Needs program by assessing the vulnerability to climate change of 7-10 additional northeastern habitat types, including forests, wetlands, and aquatic systems. Tidally-influenced habitat vulnerability was also assessed and included development of a database of ongoing coastal climate change projects and tools.The project will also build capacity in the Northeastern states for Regional Vulnerability Assessments and will coordinate with NOAA in the development of an on-line catalog of coastal climate change assessments.
This project will use more than 10 years of monitoring data to develop biometric habitat models for 9 of the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative’s species endpoints within the open pine woodland and savanna habitat type. This project will also evaluate desired ecological states as defined in the Integrated Science Agenda for their ability to predict species occurrence and identify habitat attributes that can be manipulated to create suitable habitat conditions for these species.
The Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative Geomatics Working Group developed an on-line platform to serve geospatial data in a consistent manner that also allows end-users to easily discover, access, and integrate existing data and tools without dedicated GIS software or expertise.

Many ecosystem models, particularly those that are “mechanistic” (based on an understanding of processes), are over-parameterized (not identifiable). As a result, model parameters are selected (not estimated using an optimization technique), parametererror/covariance terms become extremely difficult to estimate, and Monte Carlo error propagation does not adequately capture the effect of all uncertain model terms. In those situations, techniques that evolved from Regional (Generalized) Sensitivity Analysis (RSA), such as Generalized Likelihood Uncertainty Estimation (GLUE), Bayes Monte Carlo, and Markov Chain Monte Carlo (MCMC), are preferred techniques for model error propagation. These techniques can be used to...

The Appalachian LCC is currently engaged in an effort to develop a draft regional conservation plan for the Cooperative using an interactive and iterative spatial prioritization framework. Using available data and modeling approaches that are well supported in the literature, researchers from Clemson University are developing conservation planning models that include site selection, ecological threat assessments, and broad ranging habitat and ecological connectivity analyses.The research team is working closely with designated technical teams from each major region in the Appalachian LCC to offer unique insights and input to help guide the interactive conservation planning process. After each round of feedback,...

Provision of shade via riparian restoration is a well-established management adaptation strategy to mitigate against temperature increases in streams. Effective use of this strategy depends upon accurately identifying vulnerable, unforested riparian areas in priority coldwater stream habitats. An innovative riparian planting and restoration decision support tool is now available to the conservation community. This user-friendly tool allows managers and decision-makers to rapidly identify and prioritize areas along the banks of rivers, streams, and lakes for restoration, making these ecosystems more resilient to disturbance and future changes in climate.This research developed and implemented a user-friendly web-based...
