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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.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 1980- 1989, fires burned 32 440 km² of boreal forest, 200 km south of the forest-tundra border in northern Quebec, Canada. An assessment of the impact of fire on tree population densities was carried out by comparing the number of Pinus banksiana and Picea mariana in 83…

We present a simple empirical model that allows an estimation of mortality due to spruce budworm (Choristoneura fumiferana) outbreak in relation to fire frequency and site characteristics. The occurrence of a recent spruce budworm outbreak around Lake Duparquet (48º 30' N, 79º…

In this study, we measured rough harvester ant, Pogonomyrmex rugosus Emery, foraging activity, numbers and types of food items collected by foragers, ant foraging efficiency, and maximum foraging distances in a desert grassland site in central New Mexico before and after an…

We review and compare well-studied examples of five large, infrequent disturbances (LIDs)--fire, hurricanes, tornadoes, volcanic eruptions, and floods--in terms of the physical processes involved, the damage patterns they create in forested landscapes, and the potential impacts…

In this article, we develop a heuristic model of ecosystem-disturbance dynamics that illustrates a range of responses of disturbance impact to gradients of increasing disturbance extent, intensity, or duration. Three general kinds of response are identified and illustrated: (a)…

All species have evolved in the presence of disturbance, and thus are in a sense matched to the recurrence pattern of the perturbations. Consequently, disturbances within the typical range, even at the extreme of that range as defined by large, infrequent disturbances (LIDs),…

Because some consequences of fire resemble the effects of industrial forest harvesting, forest management is often considered as a disturbance having effects similar to those of natural disturbances. Although the analogy between forest management and fire disturbance in boreal…

Mimicking of natural disturbance for ecosystem management requires an understanding of the disturbance processes and the resulting landscape patterns. Since fire is the major disturbance in the boreal forest, three widely held beliefs about fire behavior and resulting landscape…

Regenerating oak stands on productive upland sites is widely recognized by foresters as a major problem in hardwood management. Recent research indicates that oak regeneration is more resistant to surface fires than its primary competitors on these sites if burning occurs 3 to 5…

The National Association of State Foresters fully supports the Federal Wildland Fire Management Policy and stands ready to work with our federal partners to implement the recommendations. It is unfortunate, however, that states couldn't have been directly involved in development…

The strategy of managing for 'natural' patterns towards ecological sustainability of forests is currently limited to simple spatial attributes of landscapes. Yet, there is general agreement that landscapes are highly dynamic entities suggesting that temporal patterns may also be…

A stirred water calorimeter measured the total downward heat load beneath a simulated smoldering organic soil of peat moss. Moisture and inorganic ratios (fraction of water and inorganic contents relative to organic dry mass) of the peat moss ranged from 0 to 0.6 and near 0 to 4…

Public perceptions of risk and acceptability of forest vegetation management alternatives in Ontario
We examined public perceptions of risk and acceptability for 9 alternatives to controlling forest vegetation in Ontario (N = 2.301) in the fall of 1994. The proportion of respondents indicating whether an alternative was 1) difficult to control, 2) potentially catastrophic, 3) a…

A probability-based sampling scheme was used to survey plant species composition in forests of 16 states in seven geopolitical regions of the United States (California. Colorado, Minnesota, and parts of the Pacific Northwest, Southeast, Mid-Atlantic, and Northeast) in 1994. The…

Deciduous forests in much of southern Sweden are often located on former 'in-field' sites close to farms and villages. The more distant 'out-field' sites are almost always dominated by conifers. Using palaeecological methods, we investigate the origin of this forest pattern at a…

The spatial and temporal occurrence of large grassland fires (>2008 ha) in the Intermountain West was examined for the period 1980 through 1995. Results suggest that these fires are largely predictable through space and time. Of the 360 large fires, 339 occurred within eight…

Each day, forest fire managers must deploy airtankers at initial attack bases to minimize initial attack response times. They must decide how many airtankers to deploy at each base and the initial attack range of each airtanker. We develop a daily airtanker simulation model and…
