Why pfc prichard et al 1998
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
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



Recovery rates non functional

  • 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
Good Resource Objectives

Describe the continuing resource attributes

to be achieved by management

Achievable,

Measurable,

Worthy


Objectives should be
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
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?

(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 %

Core grazing management principles
Core Grazing Management Principles using baseline data and experience

  • 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 using baseline data and experience

  • 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 using baseline data and experience

Supports

PFCdoes notequal

  • Desired Future Condition (DFC)

PFCdoes notreplace

  • Legal Requirements, e.g., ESA, CWA


  • 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
