A combination of geology, climate, geomorphology, morphometry, and vegetation that reveals similarities on a landscape. Classification and mapping of ecosystems Based on biotic and abiotic factors Similar capabilities and potentials for management Addresses sensitivity and resiliency of a landscape
Organizing and designing LTA map units Provides higher altitude view of Forest Provides means to analyze landscape at Regional and National level Inherent properties of soils and vegetation primary factors organizing management Identifies limitations for management options (geologic hazards) - Put Forest overview map here. -
Land use potential Capabilities, limitations Forest, grazing facilities, roads, transport, recreation, energy Hazards – slope stability, rockfall Fires Spread/Capture Put graphic of landslide terrain here.
Understanding watershed processes storm precipitation response water transport and availability Undestanding groundwater storage and recharge Understanding erosion and sediment Erosion rates and volumes Sediment storage and routing Put graphic here of a highly dissected, erodsing landscape adjacent to a more planear, hillslope in a single or adjacent watersheds to discuss understanding erosion and sediment transport in a watershed.
Wildlife habitat Migration corridors Aquatic habitat Stream dynamics Put graphic of meandering stream corridors here
