Fire history in three vegetation types on the eastern side of the Oregon Cascades

Creator:

Bork, Joyce L.

Abstract:

Historic fire return intervals in three different vegetation types dominated by ponderosa pine (Pinus ponderosa Laws.) were determined using fire scarred trees. Dendrochronological techniques were used to achieve accuracy in dating fire scars on samples collected from six 40 acre plots established in each site. Mean fire return intervals (MFRI)...

Four centuries of soil carbon and nitrogen change after severe fire in a Western Cascades forest landscape

Creator:

Giesen, Thomas William

Abstract:

Fire is a major disturbance process in many forests. Long-term studies of the biogeochemical effects of fires, especially on soils, are very rare. Consequently, long-term effects of fire on soils are often hypothesized from short-term effects. In a chronosequence study, I studied 24 western Cascades (Oregon) forest stands thought to...

Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:

Johnston, James D.

Abstract:

The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....
