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

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.
