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...
These raster datasets represent historical stand age. The last four digits of the file name specifies the year represented by the raster. For example a file named Age_years_historical_1990.tif represents the year 1990. Cell values represent the age of vegetation in years since last fire, with zero (0) indicating burned area in that year. Files from years 1860-2006 use a variety of historical datasets for Boreal ALFRESCO model spin up and calibration to most closely match historical wildfire dynamics.

The Integrated Ecosystem Model is designed to help resource managers understand the nature and expected rate of landscape change. Maps and other products generated by the IEM will illustrate how arctic and boreal landscapes are expected to alter due to climate-driven changes to vegetation, disturbance, hydrology, and permafrost. The products will also provide resource managers with an understanding of the uncertainty in the expected outcomes.
Baseline (1961-1990) average winter temperature in and projected change in temperature for for the northern portion of Alaska. For the purposes of these maps, ‘winter’ is defined as December - February. The Alaska portion of the Arctic LCC’s terrestrial boundary is depicted by the black line. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS3.1 data and downscaled to 2km grids; results for the other time periods (2010-2039, 2040-2069, 2070-2099) are based on the SNAP 5-GCM composite using the AR5-RCP 8.5, downscaled to 2km grids.

The Gyrfalcon, the largest falcon, is an iconic bird of the circumpolar arctic and subarctic. Thisspecies nests primarily on precipitous cliff faces and typically utilizes nests built by other species(particularly Common Raven, Golden Eagle, and Rough-legged Hawk) (Booms et al. 2008).Gyrfalcon main prey includes bird species ranging in size from passerines to geese whileptarmigan are the preferred prey. Although not well documented, in winter this species movessouth throughout Canada and sometimes into the northern lower 48. Current population on theNorth Slope (tundrius subspecies) is estimated at 250 breeding pairs (USFWS 2000).
The Red-necked Phalarope commonly breeds in both the Brooks Range foothills and ArcticCoastal Plain of Alaska. In Alaska, this species typically nests in wet tundra near water’s edge.It differs from the Red Phalarope in that it breeds further inland and at higher elevations (Rubegaet al. 2000). Like other phalaropes, this species depends on aquatic food sources for much of itsdiet (Rubega et al. 2000). Red-necked Phalaropes spend winter at sea in tropical waters in largenumbers off the west coast of South America (Rubega et al. 2000). Current North Americanpopulation estimate is 2.5 million with a declining trend (Morrison et al. 2006).
Potential Evapotranspiration (PET): These data represent decadal mean totals of potential evapotranspiration estimates (mm). The file name specifies the decade the raster represents. For example, a file named pet_mean_mm_decadal_MPI_ECHAM5_A1B_annual_2000-2009.tif represents the decade spanning 2000-2009. The data were generated by using the Hamon equation and output from ECHAM5, a fifth generation general circulation model created by the Max Planck Institute for Meteorology in Hamburg Germany. Data are at 2km x 2km resolution, and all data are stored in geotiffs. Calculations were performed using R 2.12.1 and 2.12.2 for Mac OS Leopard, and data were formatted into geotiffs using the raster and rgdal packages. Users...
This raster, created in 2010, is output from the Geophysical Institute Permafrost Lab (GIPL) model and represents simulated active layer thickness (ALT) in meters averaged across a decade. The file name specifies the decade the raster represents. For example, a file named ALT_1980_1989.tif represents the decade spanning 1980-1989. Cell values represent simulated maximum depth (in meters) of thaw penetration (for areas with permafrost) or frost penetration (for areas without permafrost). If the value of the cell is positive, the area is underlain by permafrost and the cell value specifies the depth of the seasonally thawing layer above permafrost. If the value of the cell is negative, the ground is only seasonally...
This pilot project has initiated a long-term integrated modeling project that aims todevelop a dynamically linked model framework focused on climate driven changes tovegetation, disturbance, hydrology, and permafrost, and their interactions and feedbacks.This pilot phase has developed a conceptual framework for linking current state-of-thesciencemodels of ecosystem processes in Alaska – ALFRESCO, TEM, GIPL-1 – and theprimary processes of vegetation, disturbance, hydrology, and permafrost that theysimulate. A framework that dynamically links these models has been defined and primaryinput datasets required by the models have been developed.
Baseline (1961-1990) average winter total precipitation and projected change in precipitation for the northern portion of Alaska. For the purposes of these maps, ‘winter’ is defined as December - February. The Alaska portion of the Arctic LCC’s terrestrial boundary is depicted by the black line. Baseline results for 1961-1990 are derived from Climate Research Unit (CRU) TS 3.1.01 data and downscaled to 2km grids; results for the other time periods (2010-2039, 2040-2069, 2070-2099) are based on the SNAP 5-GCM composite using the AR5-RCP 8.5, downscaled to 2km grids.

The Database was built to enable data integration across sources, as well as to support program planning and observational network design. The Imiq Data Portal provides a snapshot of available hydroclimate data – a map-based view of where , what , and when data have been obtained. Users can submit a custom data query, specifying variable of interest, geographic bounds, and time step. Imiq will aggregate and export data records from multiple sources in a common format, with full metadata records that provide information about the source data.

The Arctic Tern completes annual epic migrations from pole to pole covering at least 40,000 kmon their round-trip journeys. They breed throughout Arctic Alaska from boreal to tundra habitatsand have their highest nesting densities inland (Lensink 1984). Arctic Terns typically choose nestsites on open ground near water and often on small islands in ponds and lakes (Hatch 2002).Arctic terns consume a wide variety of fish and invertebrate prey, fish are particularly importantduring the breeding season for feeding young (Hatch 2002). This species spends their winters(austral summers) in offshore waters near Antarctica (Hatch 2002). Alaskan Arctic Coastal Plainpopulation estimates from 2011 range from 7-12,000 (Larned...
The Pectoral Sandpiper is one of the most abundant breeding birds on the Arctic Coastal Plain ofAlaska. They typically have low nest site fidelity which is likely related to their promiscuousmating strategy, thus nest densities are highly variable from year to year at a given site (Holmesand Pitelka 1998). In Arctic Alaska, primary breeding habitat includes low-lying ponds in a mixof marshy to hummocky tundra and nests are typically placed in slightly raised or better drainedsites (Holmes and Pitelka 1998). Pectoral Sandpipers spend their winters primarily in southernSouth America (Holmes and Pitelka 1998). The current North American population estimate is500,000 and they are believed to be declining (Morrison et...

Systematic conservation planning is well suited to address the many large-scale biodiversity conservation challenges facing the Appalachian region. However, broad, well-connected landscapes will be required to sustain many of the natural resources important to this area into the future. If these landscapes are to be resilient to impending change, it will likely require an orchestrated and collaborative effort reaching across jurisdictional and political boundaries. The first step in realizing this vision is prioritizing discrete places and actions that hold the greatest promise for the protection of biodiversity. Five conservation design elements covering many critical ecological processes and patterns across the...
