why is monitoring important
Why is monitoring important?
  • Identify existing and desired position on ROS
  • Promote accountability by park and resource managers
  • Foster user support for agencies
  • Identify increased demand
  • Provide feedback for better planning and management
  • Identify all impacts, not just economic
what is carrying capacity
What is carrying capacity?

Definition:

  • The maximum level of use that an area or resource can sustain before deterioration occurs.
types of carrying capacity
Types of Carrying Capacity
  • Ecological or biological
  • Social and psychological
  • Physical (facility)
  • Managerial
what do we measure
What do we measure?
  • Minimum numbers (at which a park is viable)
  • Maximum numbers

problem with cc
Problem with CC...
  • Often the impacts have already occurred by the time the CC is determined
  • No ecosystem is static, but CC is!
  • Difficult to implement in multiple use areas
    • 10 hikers
    • 8 hikers and 2 mountain bikers
    • 5 hikers and 5 mountain bikers
    • 3 hikers and 7 mountain bikers
what is lac
What is LAC?
  • A process which requires managers to:
    • define desired resource conditions and
    • take actions to maintain or achieve those conditions

It does not prevent changes but instead minimizes them!

some details about lac
Some details about LAC...
  • Monitoring-based resource assessment method
  • Considers preservation or conservation versus use
  • Based on ROS classes
  • Sets standards of use and management
  • Public involvement process
lac is not carrying capacity
LAC is NOT Carrying Capacity
  • Issue is not numbers for LAC, but IMPACTS
  • For example:
    • 10 hikers
    • 8 hikers and 2 mountain bikers
    • 5 hikers and 5 mountain bikers
    • 3 hikers and 7 mountain bikers
four major components of lac
Four Major Components of LAC
  • Specify acceptable and achievable resource and social conditions.
  • Analyze the relationship between existing conditions and acceptable conditions.
four major components of lac18
Four Major Components of LAC
  • Identify management actions necessary to achieve the desired conditions.
  • Monitor and evaluate the effectiveness of management actions.
step 1 identify area issues and concerns
Step 1 - Identify area issues and concerns
  • Identify public issues and managerial concerns that relate to:
    • Distinctive features and characteristics of the area.
    • Use of the area by people.
    • The relationship of the area to other similar units and to other local areas
step 2 define describe opportunity classes
Step 2--Define & describe opportunity classes
  • Identify ROS Opportunity Classes that generally describe the area
  • Each park area can have multiple classes

Roaded

Natural

Primitive

Semi-Primitive

Non-motor

Semi-

Primitive

Motorized

Rural

Urban

step 2 define describe opportunity classes21
Step 2--Define & describe opportunity classes
  • Describe the kinds of resource, social, and managementconditions acceptable for the class
  • Example: Primitive ROS class:
    • Resource: Minimal impacts on resource
    • Social: Solitude
    • Management: Minimal facility development
    • Management: No motorized vehicle use
step 3 select indicators of resource social conditions
Step 3—Select indicators of resource & social conditions
  • Indicators: Specific variables that indicate the condition of the opportunity class
  • Example: solitude - number of people encountered
step 3 select indicators of resource social conditions23
Step 3—Select indicators of resource & social conditions
  • Indicators must be:
    • accurate
    • capable of being measured in a cost effective way
    • related to the use occurring
    • responsive to management control.
why are indicators important
Why are indicators important?
  • Allow managers to:
    • Unambiguously define desired conditions
    • Assess the effectiveness of various management practices
indicators for primitive ros class
Indicators for primitive ROS class
  • Minimal impacts on resource:
    • Loss of vegetation along trails
  • Solitude:
    • Few encounters with other people
step 4 inventory existing conditions
Step 4 — Inventory existing conditions
  • Use indicators from Step 3 to inventory existing conditions.
  • This is a critical step in determining what and where management is needed.

step 5 specify standards for indicators
Step 5—Specify standards for indicators
  • Assign standards (i.e., quantitative measures) to indicators (from Step 3)
  • Standards provide a BASELINE against which conditions can be judged
  • Judgmental process, but logical, traceable, and subject to public review
standards for primitive ros class
Standards for primitive ROS class
  • Minimal impacts on resource:
    • Indicator: Loss of vegetation along trails
    • Standard: Trail width no more than 2 feet
  • Solitude:
    • Indicator: Few encounters with others
    • Standard: 0 - 1 encounters/day
step 6 identify alternative opportunity class allocations
Step 6—Identify alternative opportunity class allocations
  • Decide what our ROS alternatives are
    • A diversity of opportunity classes may be represented in one park.
  • Balance desired conditions with reality
    • Need input from both managers & users

step 7 identify management actions for each alternative
Step 7—Identify management actions for each alternative
  • For each alternative, identify differences between current conditions (step 4) and the standards (step 5)
    • When conditions exceed standards, there is no need for management
    • When conditions are close to or worse than standards, management is necessary
  • Design management strategies for each alternative.

  • Minimal impacts on resource:
    • Indicator: Loss of vegetation along trails
    • Standard: Trail width no more than 2 feet
    • What we have: Trail width of 1 foot
    • Management strategy?
  • Solitude:
    • Indicator: Few encounters with others
    • Standard: 0 - 1 encounters/day
    • What we have: 5 encounters/day
    • Management strategy?
step 8 evaluate and select a preferred alternative
Step 8—Evaluate and select a preferred alternative
  • Selections is made by managers and local residents…no formula
  • Considerations:
    • What user groups are affected and how?
    • What values are promoted or diminished?
    • Does the alternative contribute to park/wilderness system diversity?
    • What is feasible (personnel, budget…)?
step 9 implement actions monitor conditions
Step 9—Implement actions & monitor conditions
  • Systematic feedback on how well management actions are working
  • Identify trends in conditions that require new actions
  • Show what type of management actions solve what type of problems
