Selected Key Elements of Forest Watershed Management: 1.Riparian Buffer Delineation and Management 2.Cumulative Effects Analysis 3.Watershed Analysis
6
Riparian zone Three-dimensional zones of direct interaction between terrestrial and aquatic ecosystems (Gregory et al. 1991)

An Idealized Riparian Zone Maser and Sedell 1994 6 Nutrient uptake/filtration Sediment retention Bank stabilization Stream discharge Stream temperature Light availability Organic inputs (inverts, leaves & POM, wood) Aquatic communities (periphyton, invert., vert.)

Riparian Buffers Two Key Questions: 1. How wide and where? 2. What management inside the buffers is appropriate?

Watershed Analysis Watershed analysis is a procedure used to characterize the human, aquatic, riparian, and terrestrial features, conditions, processes, and interactions within a watershed. It provides a systematic way to understand and organize ecosystem information. Watershed analysis enhances our ability to estimate direct, indirect, and cumulative effects of management activities and guide the general type, location, and sequence of appropriate management activities within a watershed
34
Federal Watershed Analysis Procedure Step 1.Characterize the watershed Step 2.Identify issues and key questions Step 3.Describe current conditions Step 4. Describe reference conditions Step 5.Synthesize and interpret results Step 6.Develop recommendations
35
Modules Erosion processes Hydrology Vegetation Stream channel Water quality Species and habitats (aquatic and terrestrial) Human uses
36
Watershed Analysis Products 1.A description of the watershed, including its natural and cultural features 2.A description of the beneficial uses and values 3.When supporting data allow, statements about compliance with water quality standards 4.A description of the distribution, type, and relative importance of environmental processes 5.A description of the watershed’s present condition relative to its associated values and uses 6.A map of possible riparian reserves or buffers
