Tundra Fire Regimes in the Noatak River Watershed, Alaska
The location, cause, frequency, size, rotation times, and seasonal timing of tundra fires in the Noatak River watershed of northwestern Alaska were determined from Bureau of Land Management fire records for 1956-83 and satellite (LANDSAT) 1:1 000 000 scale, black and white, band 7 imagery for 1972-81. Seventy-nine fires that burned 1018 km2 were detected during the 28-year period from 1956 to 1983. Most of these occurred on the valley floor below…
Tussock Replacement as a Means of Stabilizing Fire Breaks in Tundra Vegetation
Although firebreaks in tundra areas will not always be constructed in areas of tussock and dwarf shrub vegetation, the results of our study suggest that vegetation replacement or mulching should be attempted wherever the nature of the topography suggests that post-fire erosion might occur. Natural revegetation of firebreaks in tundra areas is extremely slow, and artificial stabilization techniques may be the only alternative, despite their high c…
