The PFC concept is: • Based on the fact that systems need to be functional before they can produce aquatic or riparian values – or desired conditions

PFC Desired Future Conditions Current Conditions
Why PFC (Prichard et al. 1998)? • PFC Provides necessary broad scale perspective • Triage: Assign priority order to projects where resources can be best used, are most needed, or are most likely to achieve success • Focus on FAR reaches w/high values (to avoid loss of function & values) • Focus management & monitoring to on “no answers” • Appropriate time for experienced IDT to locate representative DMAs
WHY PFC? • Broad scale assessments provide landscape scale overview of existing conditions… • define the scope of the issues/problem… • develop solutions that become alternatives)… • Focusing on physical functioning helps communicate among stakeholders
Step 1: Assess riparian resource function using PFC Identify assessment area and assemble an ID team Review existing information and delineate and stratify reaches Determine reach potential Complete PFC assessment (validate with monitoring data if necessary) Integrated Riparian Management
Step 1: Assess riparian resource function using PFC Step 2: Identify riparian resource values and complete additional assessments Step 3: Identify issues, goals, actions and priorities and establish objectives Identify issues, goals, actions, and priorities Collect baseline data and establish or modify existing objectives Step 4: Design and implement management and restoration actions Monitor Adaptive Actions Step 5:Monitor and analyze effectiveness of actions and update resource condition ratings (PFC) Modify Objectives if Necessary Step 6: Implement adaptive actions

Management needs change • Continue what works • Focus on risks: • Trampling - season of use • Weak plants - duration of use • Up or Downstream - water, sediment, ___? • Focus on recovery: • Willows - season of use, rest • Sedges - rotation, duration • F. Continue what works
Good Resource Objectives Describe the continuing resource attributes to be achieved by management Achievable, Measurable, Worthy
Objectives should Be: Specific –What will be achieved, where, and when Measurable –With recognized monitoring methods Achievable – With likely management Realistic – Within the timeframe and budget Trackable – Within law, policy, plans, and issues
A Management Chain Reaction • Rotation grazing for three weeks (or other strategy) leads to • A four inch stubble height and 85% growing season recovery leads to • An increase in colonizers leads to • Deposition there of fine sediments leads to • An increase in stabilizers leads to • Narrowing a stream leads to • Increased floodplain access & aquifer recharge leads to • Improved base flow leads to • Improved water and habitat quality leads to • Increased fish populations leads to • Increased recreationist satisfaction • So, which of these provides the best focus for an objective?
A Management Chain ReactionWhere is the objective? Efficiently Monitored Actions or tools • Rotation grazing • A four inch stubble height • and 85% growing season recovery • An increase in colonizers • Deposition there of fine sediments • An increase in stabilizers • Narrowing a stream • Increased floodplain access & aquifer recharge • Improved base flow etc. • Improved habitat quality • Improved water quality • Increased fish populations • Increased recreationist satisfaction Efficiently Monitored (MIM) Objectives PFC Values (difficult to monitor)
Objectives should be quantified for a specific location using baseline data and experienceFor example: • At the Designated Monitoring Area 2 on Bear Camp Creek: • Increase colonizers by X % • Increase stabilizers by Y % • Narrow the greenline to greenline width by Z %

More generally successful than not Generally successful Early use Short duration Cool season Riparian pasture Rotate use areas and timing Light to moderate use Long recovery periods Regrowth before winter Jumpstart or occasional rest Stutter deferred More off-riparian water Well scattered supplements/salt Cleaned pastures and closed gates PFC – Resilience Select for hill climbers Riding for animal placement Yearlings • Generally unsuccessful • Season-long use • Long season of use • Hot or dry growing season use • Giant pastures - upland objectives • Consistent seasonal use • Heavy use too often • Little time for regrowth • Late use • Annual use • Little woody recovery • Only riparian water • Salt on creeks • Stragglers • At risk or nonfunctional • Retain riparian dwellers • Little or no riding • Cow calf pairs
Core Grazing Management Principles • Avoid stress on important forage plants • Moderate or lower utilization OR • Graze for only a short period when plants are growing (shorter when growing faster) • Provide long growing season recovery with no grazing before next use • Graze in a different season at next use
PFC in Documents • Communicating with stakeholders • Purpose and need • Description of the existing environment • Selection of alternatives • Effects of proposed actions • Planning monitoring • Criteria for adapting management
Supports Supports PFCdoes notequal • Desired Future Condition (DFC) PFCdoes notreplace • Legal Requirements, e.g., ESA, CWA
Understand what can be achieved • Provide linkage between reach/watershed • processes and habitat/water quality conditions • Define/prioritize issues to address • Select appropriate management practices PFC Helps • Strategize appropriate monitoring • Communicate among stakeholders
