1
Watersheds Capture, Store And Safely Release Water
2
RIPARIAN AREAS A form of wetland transition between permanently saturated wetlands and uplands areas Exhibit vegetation or physical characteristics of permanent surface or subsurface water Examples: LAND ADJACENT to PERENNIAL or INTERMITTEN FLOWING STREAMS, LAKESHORES, GLACIAL POTHOLES
3
NATURAL RIPARIAN RESOURCES
4
PROPER FUNCTIONING CONDITION RIPARIAN-WETLAND areas are functioning properly when adequate vegetation, landform, or large woody debris is present to: –Dissipate STREAM ENGERGY associated with high flows –Filter SEDIMENT and CAPTURE BED LOAD –Aid FLOODPLAIN DEVELOPMENT –Improve FLOOD WATER RETENTION and GROUNDWATER RECHARGE –Stabilize STREAMBANKS
5
PROPER FUNCTIONING CONDITION ACHIEVED PROVIDES FOR: FISH Habitat for FISH and WILDLIFE Improved WATER QUALITY Improved FORAGE PRODUCTION SOIL Decreased SOIL EROSION Greater BIODIVERSITY
6
FUNCTIONAL AT RISK RIPARIAN-WETLAND areas that are in Functional Condition, but an existing Soil, Water, or Vegetation attribute makes them SUSCEPTIBLE TO DEGRADATION
7
NONFUNCTIONAL RIPARIAN-WETLAND areas that CLEARLY ARE NOT PROVIDING adequate Vegetation, Landform or Large Woody Debris to: Dissipate Stream Energies associated with higher flows Filter Sediment and Capture Bedload Aid in Floodplain Development Improve Floodwater retention and Groundwater Recharge Stabilize Streambanks
8
NONFUNCTIONAL Areas that are Nonfunctional –DO NOT provide Wildlife Habitat –DO NOT provide improved Water Quality –DO NOT improve Forage Production –EXHIBIT INCREASED Soil Erosion –EXHIBIT DECREASED Biodiversity

STREAM CROSS SECTIONS
26
POTENTIAL The highest ecological status a Riparian-Wetland area can attain given no political, social, or economical constraints
27
MAJOR STREAM TYPES LONGITUDINAL, CROSS-SECTION, AND PLAN PROFILES
28
DETERMINATION OF RIPARIAN-WETLAND SYSTEMS CAPABILITY AND POTENTIAL Relic areas information Historic information Species Lists Habitat Needs Soils Information Hydrology Information Current Vegetation Watershed Condition/Major Landforms Limiting Factors
31
PFC Vulnerable Time Decision Space Fisheries Values Livestock Values Recreation Values Wildlife Values Watershed Values Desired Condition Bare Ground PNC

4.) RIPAIAN ZONE IS WIDENING OR HAS ACHIEVED POTENTIAL EXTENT.
33
VEGETATION

6.) DIVERSE AGE-CLASS DISTRIBUTION (RECRUITMENT FOR MAINTENANCE/RECOVERY

6.) DIVERSE AGE-CLASS DISTRIBUTION (RECRUITMENT FOR MAINTENANCE/RECOVERY
37
7.) DIVERSE COMPOSITION OF VEGETATION (FOR MAINTENANCE/RECOVERY)
38
8.) SPECIES PRESENT INDICATE MAINTENANCE OF RIPARIAN SOIL MOISTURE CHARACTERISTICS
39
9.) STREAMBANK VEGETATION IS COMPRISED OF THOSE PLANTS OR PLANT COMMUNITIES THAT HAVE ROOT MASSESS CAPABLE OF WITHSTANDING HIGH STREAM FLOW EVENTS
40
10.) RIPARIAN PLANTS EXHIBIT HIGH VIGOR
41
11.) ADEQUATE VEGETATIVE COVER PRESENT TO PROTECT BANKS AND DISSIPATE ENERGY DURING HIGH FLOWS
42
12.) PLANT COMMUNITIES IN THE RIPARIAN AREA ARE AN ADEQUATE SOURCE OF COARSE AND/OR LARGE WOODY DEBRIS
45
PLANNING PROCESS STEP 1. EXISTING CONDITION STEP 2. POTENTIAL CONDITION STEP 3. PFC STEP 4. RESOURCE VALUES STEP 5. MANAGEMENT GOALS and OBJECTIVES STEP 6. PLANNED ACTIONS STEP 7. MONITORING STEP 8. FLEXIBILITY
46
SUMMARY MINIMUM ASSESSMENT TOOL PFC USUALLY NOT THE SAME AS DFC POTENTIAL VS. CAPABILITY QUALITATIVE VS. QUANTITATIVE INTERDISCIPLINARY TEAM BE CONSERVATIVE DO THE PREP. WORK NORMAL STREAM PROCESSES (25 YR FLOOD EVENT)
47
WHY MAKE THE INVESTMENT IN PFC?? ENGAGES PUBLIC IN COOPERATIVE RIPARIAN RESTORATION MANY RIPARIAN PROBLEMS ARE CAUSED OR AGGRAVATED BY OFF-SITE MANAGEMENT AN ID TEAM CREATES AN INTERDISCIPLINARY BASIS FOR INTERATED MANAGEMENT QUALITATIVE ASSESSMENT SUPPORTED BY QUANTITATIVE SCIENCE WITH MEASUREMENT TOOLS WHEN NEEDED
48
WHY MAKE THE INVESTMENT IN PFC?? FOCUS FUTURE MONITORING ON KEY DATA NEDED TO CHECK MANAGEMENT PROVIDES A FRAME WORK FOR INTERPRETING ALL OTHER WATERSHED AND STREAM DATA MANDATED BY GOVT. TWO LEVELS –ID TEAM IN FIELD –AIR PHOTOS
