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.
This project resulted in an extensive mapping of coastal change along the entire coastline of the Western Alaska Landscape Conservation Cooperative (LCC). The work provides important baseline information on the distribution and magnitude of landscape changes over the past 41 years. The extent of change to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons, was known to be substantial in some areas along the coast (e.g., portions of the Yukon–Kuskokwim Delta), although the extent of change along the full Bering Sea coast was not well documented. With this analysis, changes can be summarized for different land ownerships or other units to assess the extent of recent...

The western coastline of Alaska is highly susceptible to coastal storms, which can cause coastal erosion, flooding, and have other pernicious effects to the environment and commercial efforts. The reduction in ice coverage due to climate change could potentially increase the frequency and degree of coastal flooding and erosion. Further, estuaries and delta systems act as conduits for storm surges, so when there is less nearshore ice coverage, these systems could introduce storm surge into terrestrial environments unaccustomed to saline intrusion, flooding, or other alien biogeochemical factors.​This project quantified the effect of reduced nearshore ice coverage on coastal flooding. The project developed a large...
Research on coastal change in Western Alaska has increased rapidly in recent years, making it challenging to track existing projects, understand their cumulative insights, gauge remaining research gaps, and prioritize future research. This project identified existing coastal change projects in Western Alaska that were happening in 2014, scheduled for 2015 or occured in 2012-2014. The report (below) provides a synthesis of information about each project category, and an associated online database (see ACCAP project page link below) describes individual projects and information on how to contact the project leader. These products document the project landscape for communities facing change, decision-makers navigating...

The Integrated Ecosystem Model for Alaska project (IEM) uses down-scaled climate models as the drivers of ecosystem change to produce forecasts of future fire, vegetation, permafrost and hydrology regimes at a resolution of 1km. This effort is the first to model ecosystem change on a statewide scale, using climate change input as a major driving variable. The objectives of the IEM project are as follows; to better understand and predict effects of climate change and other stressors on landscape level physical and ecosystem processes, and to provide support for resource conservation planning.The IEM will provide resource managers with a decision support tool to visualize future landscapes in Alaska. Model outputs...

These rasters represent estimated potential evapotranspiration (mm). Data were generated by using the Hamon equation and historical air temperature projections from the CRU dataset.
Baseline hydrologic and topographic data in relation to waterfowl productivity is very limited on the Y-K Delta. When considering the potential impacts of climate-driven change to nesting and brood-rearing habitats, these baseline data are important for making informed management decisions. This project takes advantage of a long-term field camp on Kigigak Island to expand instrumentation for monitoring pond water levels and salinities, and tidal dynamics. It will also support elevation surveys and the synthesis of environmental and biological datasets for inclusion in climate change models.

The Alaska Ocean Observing System, Western Alaska Landscape Conservation Cooperative (Western AK LCC), and the USGS Alaska Climate Science Center jointly conducted a Coastal Hazards Workshop May 30-31, 2012. Participants included a broad array of subject matter experts and stakeholders involved in coastal issues from a variety of perspectives. Workshop participants reviewed the current state of the coast and the state of understanding of the coast from a systems perspective, discussed stakeholder information needs and developed the framework for a conceptual model focused on natural-human system impacts due to coastal erosion and inundation.
Research and management studies on coastal change in Western Alaska has increased rapidly in recent years, making it challenging to track existing projects, understand their cumulative insights, gauge remaining information gaps, and prioritize future projects. The goal of this effort is to identify current coastal research and management projects that are taking place in Western Alaska and to synthesize information into a report that documents the ‘project landscape’ for communities facing change, decision-makers navigating change, researchers pursuing projects, as well as funding agencies trying to prioritize where to allocate resources. To identify coastal change projects, we first conducted an extensive Internet...
