Oregon Coastal Range Fire Regime Study

The purpose of this study was to characterize the fire regime of the central
Oregon Coast Range at multiple spatial scales and to compare the fire regime of
the more recent (ca. 500 years) history with longer paleo records such as
charcoal sediment deposits in lakes.

Primary data was collected from ages of trees at cutting in clearcuts (sites).
Fire scars on stumps were dated to determine dates of fires. Tree-ring counts
of stumps were analyzed to determine age class information related to fire
episodes. Sampling was carried out to determine the fire regime at three
spatial scales: climate (zone); aspect and hillslope position. The proportion
of sites for each aspect and within each zone reflected the proportion of the
study area in each aspect and zone, respectively. At each site equal sampling
occurred for each hillslope position (U, M, L). Additional descriptions of the
sampling design can be found in Chapter 2 of the dissertation "Spatial and
Temporal Patterns of Fire in the Central Oregon Coast Range"
