How Climate and Vegetation Influence the Fire Regime of the Alaskan Boreal Biome: the Holocene Perspective
We synthesize recent results from lake-sediment studies of Holocene fire-climatevegetation interactions in Alaskan boreal ecosystems. At the millennial time scale, the most robust feature of these records is an increase in fire occurrence with the establishment of boreal forests dominated by Picea mariana: estimated mean fire-return intervals decreased from ≥300 yrs to as low as ∼80 yrs. This f...
متن کاملVegetation and wildfire controls on sediment yield in bedrock landscapes
[1] Steep, rocky landscapes commonly exhibit high sediment yields and are especially sensitive to climate, tectonics, and wildfire. Predicting landscape response to these perturbations demands a quantitative understanding of erosion processes. However, existing models for hillslope sediment production and transport do not apply to landscapes with patchy soil and slopes that exceed the angle for...
متن کاملA palynological investigation of Holocene vegetation change in Torres Strait, seasonal tropics of northern Australia
The islands of Torres Strait occupy a shallow area of submerged continental shelf narrowly separating Cape York Peninsula, Australia, from New Guinea. The human history of Torres Strait is unique with respect to mainland northern Australia. Island vegetation, however, exhibits a strong affinity with the environments of the western lowlands regions of Cape York Peninsula and with the vegetation ...
متن کاملVegetation Mortality within Natural Wildfire Events in the Western Canadian Boreal Forest: What Burns and Why?
Wildfires are a common disturbance event in the Canadian boreal forest. Within event boundaries, the level of vegetation mortality varies greatly. Understanding where surviving vegetation occurs within fire events and how this relates to pre-fire vegetation, topography, and fire weather can inform forest management decisions. We used pre-fire forest inventory data, digital elevation maps, and r...
متن کاملWildfire Patterns in Western Boreal Canada
The idea of using natural patterns as guides for policy and practices continues to gain favour in forestland management. Towards this, research activities in the boreal have been focusing on the patterns and processes of wildfires over the last 15-20 years. This project is the fourth phase of a long-term research study looking at natural wildfire patterns across the forested areas of Alberta an...
