The Alaska Reference Database originated as the standalone Alaska Fire Effects Reference Database, a ProCite reference database maintained by former BLM-Alaska Fire Service Fire Ecologist Randi Jandt. It was expanded under a Joint Fire Science Program grant for the FIREHouse project (The Northwest and Alaska Fire Research Clearinghouse). It is now maintained by the Alaska Fire Science Consortium and FRAMES, and is hosted through the FRAMES Resource Catalog. The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Fire frequency is the most commonly used measure to characterize fire regimes for comparisons across geographical areas or time periods. Within the boreal forest region of the Boreal Shield ecozone of Ontario, fire frequency changes over time and across longitudinal gradients…

Bark protects both the living phloem and the vascular cambium of trees. For some tree species the bark has been observed to swell in the radial direction when heated by nearby flames, possibly providing additional protection from thermal injury. In this study, detailed…

Many biological, hydrological, and geological processes are interactively linked in ecosystems. These ecological phenomena normally vary within bounded ranges, but rapid, nonlinear changes to markedly different conditions can be triggered by even small differences if threshold…

We hypothesized that differences in microbial and plant N demand in balsam poplar and white spruce stands would control in situ net N transformation and retention following N additions. Throughout the study, N fertilizer (NH4NO3) was added in three increments during the growing…

After 6 years of intensive study, all the research studies designed to answer the information needs identified in appendix B of the Tongass land management plan have ended, with their results published or in press. The knowledge generated from these studies not only informs the…

The logic behind FEPF is straightforward: identify and map where management objectives exist on the landscape (or where their important habitats exist); identify critical fire weather threshold conditions (such as 80th, 90th, 99th percentile Energy Release Component) and map…

This study compared aspatial and spatial methods of using remote sensing and field data to predict maximum growing season leaf area index (LAI) maps in a boreal forest in Manitoba, Canada. The methods tested were orthogonal regression analysis (reduced major axis, RMA) and two…

Surface energy exchanges were measured in a sequence of five sites representing the major vegetation types in the transition from arctic tundra to forest. This is the major transition in vegetation structure in northern high latitudes. We examined the influence of vegetation…

Questions: Does post-fire plant succession in boreal bogs vary microtopographically and are successional patterns reproducible among similar microtopographic features? Does succession preserve microtopography post-fire? Location: Boreal bog peatlands near Sinkhole Lake and…

Peatlands accumulate organic matter as peat because of disproportionate rates of production and decomposition. However, peat accumulation heterogeneity has not been well studied along the microtopographic gradient (hummocks vs. hollows), particularly with respect to fire. Fire…

The dynamic global vegetation model MC1 was used to examine climate, fire, and ecosystems interactions in Alaska under historical (1922-1996) and future (1997-2100) climate conditions. Projections show that by the end of the 21st century, 75%-90% of the area simulated as tundra…

The spruce beetle, Dendroctonus rufipennis (Kirby), causes landscape level mortality to mature spruce (Picea spp.) throughout western and northern North America. As with other bark beetles, this beetle is associated with a variety of fungi, whose ecological functions are largely…

Assessment of the impacts of future climate change on the boreal forest and forest-tundra biomes relies on a clear understanding of their past dynamics. Fire history information recorded in lake and peat sediments can be retrieved by counting charcoal particles on pollen slides…

Boreal ecosystems contain a substantial fraction of the earth's soil carbon stores and are prone to frequent and severe wildfires. In this study, we examine changes in element and organic matter stocks due to a 1999 wildfire in Alaska. One year after the wildfire, burned soils…

The classification of savanna fires into headfire and backfire types can in theory help in assessing pollutant emissions to the atmosphere via relative apportionment of the amounts of smouldering and flaming combustion occurring, and is also important when assessing a fire's…

Climate warming at high latitudes is expected to increase root and microbial respiration and thus cause an increase in soil respiration. We measured the root and microbial components of soil respiration near Fairbanks, Alaska, in 2000 and 2001, in three black spruce (Picea…

There were large interannual variations in burned area in the boreal region (ranging between 3.0 and 23.6x106 ha yr-1) for the period of 1992 and 1995-2003 which resulted in corresponding variations in total carbon and carbon monoxide emissions. We estimated a range of carbon…

Fires in boreal forests frequently convert organic matter in the organic layer to black carbon, but we know little of how changing fire frequency alters the amount, composition and distribution of black carbon and organic matter within soils, or affects podzolization. We…

From introduction: Wildfire is a majoar natural disaster in the United States. In 2002, for example, tens of thousands of wildfires occurred that consumed nearly seven million acres of forest and other land cover (NIFC, 2003). Wildfires contribute to increasing atmospheric CO2…
