Forest Measurements : an Applied Approach
Forested ecosystems occupy a rich array of varied landforms. In the
Pacific Northwest, this diversity is readily apparent as one surveys the
landscape– volcanic peaks contrast with wide valleys; steep, forested
hillsides surround gently rolling savannas; and rapidly cascading
mountain streams transition to meandering river floodplains. This
varied topography is an integral part of the forest, influencing
climate, soils, water, vegetation and aquatic life (Figure 1.1). Natural
resource technicians are often called upon to assess the topography,
and one of the common elements measured is the slope of the land.
How steep is a hillside? Does it drain to a stream? Are there cliffs
or bluffs present? Topographical field data collected by technicians
are used to inform decisions about land management activities such as
providing shade for streams, building roads or trails, and prescribing
timber harvesting operations.
