Maritime forests are a unique group of forest ecosystems, linking marine and terrestrial environments. The Pacific coastal temperate rainforest (PCTR) is one of the most intact in the world and is currently the site of an increasing amount of ecological and climate effects research.

Our partners at the Pacific Northwest Research Station have been conducting long term projects in PCTR to expand our understanding of temperate rainforest ecosystems and the effects of climate change on those ecosystems. The papers below are a result of some of their crucial work in the PCTR.
Life on the Edge: Carbon Fluxes from Wetland to Ocean Along Alaska's Coastal Temperate Rain Forest
Acre for acre, streams of the coastal temperate rainforest along the Gulf of Alaska export 36 times as much dissolved organic carbon as the world average. Dissolved organic carbon derived from soils has a large biodegradable component, making it an important food source for freshwater and marine food webs. In the Tongass National Forest alone, there are 14,000 streams exporting these high-value nutrients to the estuaries that support Alaska’s $5 billion fishing industry.
Forests in Decline: Yellow-Cedar Research Yields Prototype for Climate Change Adaptation Planning
Yellow-cedar has been dying across 600 miles of North Pacific coastal rain forest—from Alaska to British Columbia—since about 1880. Thirty years ago, a small group of pathologists began investigating possible biotic causes of the decline. When no biotic cause could be found, the scope broadened into a research program that eventually encompassed the fields of ecology, soils, hydrology, ecophysiology, dendrochronology, climatology, and landscape analysis.
Cross Boundary Data Integration Workshop II: February 1-3, 2012
Project Summary: The Alaska Coastal Rainforest Center and Southeast Alaska GIS Library at UAS held a second workshop to develop cross-boundary geospatial and climate data sets in support of regional conservation applications in the coastal temperate rainforest zone of Southeast Alaska and British Columbia. This project facilitated planning sessions and forums on technical development of standardized datasets and helped formalize a platform for coordination of data exchange and dissemination via the Southeast Alaska GIS Library. In addition, this workshop established a plan for future analytical efforts in which cross‐boundary datasets are utilized to address critical and regional conservation applications such as connectivity and dispersal, carbon budget allocation, and climate change vulnerabilities.
1. Provide opportunities for communicating and discussing priorities for the exchange, development and unification of geospatial and climate datasets.
2. Facilitate teams and work sessions to develop and rectify datasets into cross-boundary data end products.
3. Provide a forum to present and discuss ongoing development of relevant datasets.
4. Enhance an existing platform, i.e. Southeast Alaska GIS Library, for data integration and dissemination.
5. Develop a plan for future analytical efforts in which cross‐boundary datasets are utilized to address critical and regional conservation applications.
1. Cross-Boundary Applications Matrix – An organizational framework for defining, planning, prioritizing, and tracking future cross-boundary activities.
2. Data Inventory – An organizational and tracking document that lists the status and characteristics of existing datasets that may serve as the foundation for cross-boundary dataset development.
3. Funding concept – An outline of a specific research-oriented funding proposal to collaborate on in the coming calendar year, such as the NSF Research Coordination Network funding opportunity.
Location: University of Alaska Southeast, Egan Building - Glacier View Room, Juneau, AK

Cross-Boundary Data Integration Workshop I: February 16 & 17, 2011
Project Summary: The ACRC and the Southeast Alaska GIS Library sponsored a Cross-Boundary Data Integration Workshop at the University of Alaska Southeast on February 16 and 17, 2011. The workshop aimed to coordinate data integration tools to address issues of regional importance. It also initiated the implementation of a cross-boundary data management system. More than 40 people attended, some from as far away as Anchorage and Seattle, to understand and prioritize regional data needs in areas such as resource management and program funding.
- Established a forum to discuss priorities for data needs
- Explored data integration platforms (GIS Library, Data Basin, etc.)
- Presented new and ongoing projects and discussed ideas for end-user needs
- Discussed the direction of work developed through grants from the Wilburforce Foundation
- Solicited feedback on the development of online resource modules
- Discussed how the merging of cross-boundary datasets efficiently brings resource managers better products
- Completed the first work session for cross-boundary data models in Alaska and British Columbia
