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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

From the text ... 'First, the formation of PyOM [pyrogenic organic matter], regardless of the rate, does not remove CO2 from the atmosphere. When fire generates PyOM, regardless of the persistence of the resulting material, the process represents a transformation of one type of…

In the boreal forest of Alaska, increased fire severity associated with climate change is expanding deciduous forest cover in areas previously dominated by black spruce (Picea mariana). Needle-leaf conifer and broad-leaf deciduous species are commonly associated with differences…

Fire frequency has dramatically increased in the tundra of northern Alaska, USA, which has major implications for the carbon budget of the region and the functioning of these ecosystems, which support important wildlife species. We investigated the postfire succession of plant…

Purpose Rising levels of nitrogen (N) deposition are influencing urban forest carbon (C) and N dynamics due to greater human disturbance compared to those in rural areas. N deposition in combination with increased atmospheric carbon dioxide (CO2) and water limitation may alter C…

This 16-week, ex situ greenhouse misting trial was designed to isolate and compare the patterns of carbon and nutrient release from coarse woody debris (CWD). Comparisons included: hardwood (aspen) versus conifer (spruce); harvest- versus fire-origin; and among decay classes (…

Heavy grazing by extremely high densities of reindeer (Rangifer tarandus) on St. Matthew Island in the Bering Sea resulted in degradation of the lichen stands. Grasses, sedges, and other vascular plants initially increased in response to the removal of lichens under heavy…

Results are reported from observations on the characteristics and population dynamics of the principal climax species, Picea glauca, made in summer 1985 near Chitina. Data are presented on vegetation types (transect profiles), density of woodland (point-centred quarter technique…

Two stands of white spruce (Picea glauca (Moench) Voss), one on a south aspect and one on a north aspect on the Kenai Peninsula of Alaska, were sampled intensively to determine site and host variables associated with high attack densities by spruce beetle, Dendroctonus…

Laboratory experiments were conducted to investigate how both mineral soil and moisture content affect the smoldering combustion in forest duff. Peat was used to represent the fermentation and humus horizons (Oe and Oa soil horizons) of a coniferous forest floor nominally called…

Using age-structure determinations on both living and dead stems in censused plots, coupled with stem analysis techniques, an historical picture of mortality and above-ground tree stem growth was recreated for ten stands dominated by black spruce in northeastern Ontario, Canada…

This field and microscope study explores the micromorphological changes occurring in humus profiles of the Canadian boreal forest which have been variously affected by factors of disturbance: fire, dehydration and overland flow after storms. It compares the materials and…

A study was carried out to investigate the effects of slash-burning on the nutrient status of two Sub-Boreal. Spruce zone ecosystems in the west central interior of British Columbia. The slash, forest floor and mineral soil (0—15 cm depth) in these ecosystems were sampled for…

Identifying indicators of state change and forecasting future vulnerability in Alaskan boreal forest
This research is designed to understand the mechanistic connections among vegetation, the organic soil layer, and permafrost ground stability in Alaskan boreal ecosystems. Understanding these linkages is critical for projecting the impact of climate change on permafrost in…

We expand the concept of “old growth” to encompass the distinct ecologies and conservation values of the world's ancient grass-dominated biomes. Biologically rich grasslands, savannas, and open-canopy woodlands suffer from an image problem among scientists, policy makers, land…

Alaska, the great northern frontier of America, is being reshaped by climate change. While rising temperatures are altering its character and landscape, they are also bringing the ravages of wildfires. In the past 60 years, Alaska has warmed more than twice as fast as the rest…

Alaska and its neighbor to the east, Canada, have kicked off wildfire season in a major way. Blazes have raged across the northern stretches of North America, sending smoke streaming down into the Lower 48 and leaving the landscape charred. The multitudes of fires is a glimpse…

Boreal fires burn into carbon-rich organic soils, thereby releasing large quantities of trace gases and aerosols that influence atmospheric composition and climate. To better understand the factors regulating boreal fire emissions, we developed a statistical model of carbon…
