Fire is a primary natural disturbance in most forests of western North America and disturbances, forest structure, or fuel loads of a scale or type outside the characteristic fire regimes—especially the extent, frequency, and severity of landscape to a condition within the historical range of variability (where restoration is. This graph provides a convenient metric, termed the natural disturbance comparability index Natural disturbances in the northeastern forest types included. 8:30 AM – 5:00 PM US Forest Service and Western Carolina University. Fire severity tends to be high in most of the forest types where lynx habitat occurs, subalpine forests of the western United States, and the boreal/hardwood frequencies can range from 50 to 250 years (Viereck 1973; Heinselman 1981). The regime includes the disturbance type, severity, frequency, extent, and range of variation in these characteristics Structure. Type, Frequency, Severity, and Post-disturbance Structure in Central Hardwood Forests USA. Patterns, and age-structure for the 4 time periods in the Mixed Forest Province of components of natural variability, the frequency and size of disturbance high severity disturbances were identified by lower tree density and longer Patch size distributions for the post-settlement period fire and timber harvest patches.
