Attempts to stabilize the shore can greatly influence rates of shoreline change. Beach nourishment in particular will bias rates of observed shoreline change toward accretion or stability, even though the natural beach, in the absence of nourishment, would be eroding. Trembanis and Pilkey (1998) prepared a summary of identifiable beach nourishment projects in the Gulf Coast region that had been conducted before 1996. Those records were used to identify shoreline segments that had been influenced by beach nourishment. Supplemental information regarding beach nourishment was collected from agencies familiar with nourishment projects in the State. All records were compiled to create a GIS layer depicting the spatial...

This data set represents the extent, approximate location and type of wetlands and deepwater habitats in the United States and its Territories. These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their...

The Red River Stakeholder Engagement project’s primary objective was to uncover areas of concern for stakeholders who live, work, and play along the Red River Basin. It examined the complexity of the cultural-geographic landscape across the Red River Basin. By focusing on both the geographic and the cultural, we gain a better understanding of how individuals, communities, and organizations interact with the basin and with one another, how they arecurrently experiencing changes, and what they perceive a changing climate means for them.This cultural-geographic approach recognizes that stakeholders’ concerns, priorities, and actions likely vary across space-and also vary in their cultural significance. For example,...
To enhance the chances of restoring and protecting Puerto Rico’s beaches by synthesizing guidelines and procedures on beach characterization and profiling, planting, fertilization, irrigation, maintenance, monitoring, etc. and working to identify, inventory, and prioritize beaches that need and can accommodate stabilization with vegetation, or can become sources of plants for nursery propagation and planting. Information will include all permit requirements for beach restoration projects, including those associated with beaches used by sea turtles for nesting. Within the selected prioritized beaches the CAT will develop an education & awareness program, to demonstrate benefits, address needs & expectations and promote...
We are analyzing spatial factors of land cover transition in Puerto Rico and conducting state and transition simulation modeling of vegetation dynamics.
This report summarizes the results from a climate change adaptation workshop focused on the Columbia Plateau landscape in eastern Washington and parts of Idaho and Oregon. The objective of the workshop was to collaborate with landscape managers to apply results from the Pacific Northwest climate change vulnerability assessment (PNWCCVA) to on-the-ground ecological management objectives. Specifically, we sought to address the following questions: How can model results and datasets be applied to assist with management decisions? How can model results and datasets be made more useful for informing species and landscape management?To this end, we presented information and data developed as part of the PNWCCVA to workshop...

We will develop an approach to identify fire refugia in Rocky Mountain ecosystems of the U.S. and Canada then test the function of refugia for biodiversity conservation under current and future climate/fire scenarios. Our products will be designed to inform decision-making in land/easement acquisition, identification of critical areas for maintaining landscape and process connectivity/permeability, and extension of the temporal context for spatial conservation decision making. The approach will be testable for transferability to other locations and ecosystems.

The zip file below contains raw input and output files for the 4 final version of the ALI Marxan model. The versions all have the same number of runs (100), number of iterations (35 million), SPF factor for each conservation feature,(100) and BLM (0.35). They vary in overall goal levels and whether or not facets were targeted. The four versions are: (1) high overall goal levels, facets not targeted;(2) medium overall goal levels, facets not targeted; (3) medium overall goal levels, facets not targeted; (4) medium overall goal levels, facets targeted at 15%. Please see the associated report (ALI 2013) for further details, and contact Madeline with any questions.
Abstract Unpaved forest roads remain a pervasive disturbance on public lands and mitigating sediment from road networks remains a priority for management agencies. Restoring roaded landscapes is becoming increasingly important for many native coldwater fishes that disproportionately rely on public lands for persistence. However, effectively targeting restoration opportunities requires a comprehensive understanding of the effects of roads across different ecosystems. Here, we combine a review and a field study to evaluate the status of knowledge supporting the conceptual framework linking unpaved forest roads with streambed sediment. Through our review, we specifically focused on those studies linking measures of...
This document describes the long-term monitoring program of the Southwestern Crown of theContinent Collaborative (SWCC) developed as part of the Collaborative Forest Landscape RestorationProgram (CFLRP). It explains the goals, principles, organizational structure, and monitoring approach ofthe SWCC. It was developed by the members of the SWCC Monitoring Committee during 2011/2012 andwas reviewed by the full SWCC. It represents a common vision for evaluating and improving forestrestoration efforts in western Montana. The document is organized around the objectives of the ForestLandscape Restoration Act (FLRA) and the SWCC’s goals for forest restoration in the region.The SWCC identified a strong monitoring program...
The Washington Connected Landscapes Project: Statewide Analysis presented a vision for a connected network of habitats for wildlife in current condition. This climate-gradient corridor analysis and report adds a climate change lens to that assessment, by identifying corridors intended to improve the ability of wildlife and their habitats to respond to future changes in climate.A key means by which wildlife respond to climate change is to adjust their geographic ranges to track shifting areas of climatic suitability. This ability to move as conditions change will become even more critical over the coming century as climate change becomes more severe. And yet, species will increasingly encounter human-made barriers...

This categorical CWD raster was developed from a project-wide CWD raster. For each of the five fracture zones, the CWD raster was partitioned into zone-specific, 10 equal-area class map, ranging from low CWD to high CWD.
The Western Governors’ Association (WGA) sponsored an assessment of crucial habitats which will be used for the evaluation of landscape-scale energy, land use, and transportation projects throughout the western United States. The main product of the WGA’s assessment is an easily accessible online system of maps displaying crucial habitats and corridors known as the Crucial Habitat Assessment Tool (CHAT; http://www.westgovchat.org/).Crucial habitats were based on factors such as species of concern, species of economic and recreational importance, special ecological systems and habitat types, habitat corridors, native species richness, and ecological integrity (i.e., unfragmented habitats). All of these factors are...

Climate change impacts many species through shifts in habitat. The intensity of this impact will depend on the dispersal rates of the species, the patchiness of the environment, and the velocity of habitat change. Here we examine how dispersal affects projected future habitat availability for a threatened carnivore, the fisher (Pekania [Martes] pennanti). We used non-invasive genetic sampling to detect fisher across their historical distribution in Montana and Idaho. This survey included 4846 non-invasive hair snares, of which 288 identified fishers through mitochondrial DNA analysis. We modeled the distribution of fisher across western Montana and northern Idaho using a suite of vegetative, topographic, and climatic...

The Western Governors’ Association has sponsored an assessment of crucial habitats which will be used for the evaluation of landscape-scale energy, land use, and transportation projects. The main purpose of the work funded through this LCC grant is to develop an index of aquatic ecological integrity and incorporate it into Washington State’s crucial habitats assessment. Ecological integrity has been defined as the ability of an ecological system to support and maintain a community of organisms that has species composition, diversity, and functional organization comparable to those of natural habitats within a region (Parrish et al. 2003). One of our objectives is to develop an index of aquatic ecological integrity...
