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?
Definition: The maximum level of use that
an area or resource can sustain before deterioration occurs.
![Page 5: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/5.jpg)
Types of Carrying Capacity
1. Ecological or biological
2. Social and psychological
3. Physical (facility)
4. Managerial

What do we measure? Minimum numbers (at which a park
is viable)
Maximum numbers

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

LAC or Limits of Acceptable Change
![Page 14: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/14.jpg)
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!
![Page 15: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/15.jpg)
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
![Page 16: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/16.jpg)
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
![Page 17: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/17.jpg)
Four Major Components of LAC
1. Specify acceptable and achievable resource and social conditions.
2. Analyze the relationship between existing conditions and acceptable conditions.
![Page 18: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/18.jpg)
Four Major Components of LAC
3. Identify management actions necessary to achieve the desired conditions.
4. Monitor and evaluate the effectiveness of management actions.
![Page 19: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/19.jpg)
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
![Page 20: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/20.jpg)
Step 2--Define & describe opportunity classes Identify ROS Opportunity Classes that
generally describe the area
Each park area can have multiple classes
Primitive UrbanSemi-PrimitiveNon-motor
RuralRoadedNatural
Semi-PrimitiveMotorized
![Page 21: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/21.jpg)
Step 2--Define & describe opportunity classes Describe the kinds of resource,
social, and management conditions acceptable for the class
Example: Primitive ROS class: Resource: Minimal impacts on resource Social: Solitude Management: Minimal facility
development Management: No motorized vehicle use
![Page 22: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/22.jpg)
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
![Page 23: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/23.jpg)
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.
![Page 24: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/24.jpg)
Why are indicators important? Allow managers to:
Unambiguously define desired conditions
Assess the effectiveness of various management practices
![Page 25: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/25.jpg)
Indicators for primitive ROS class Minimal impacts on resource:
Loss of vegetation along trails
Solitude: Few encounters with other people
![Page 26: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/26.jpg)
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 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
![Page 29: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/29.jpg)
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
![Page 30: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/30.jpg)
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
![Page 31: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/31.jpg)

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.
![Page 36: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/36.jpg)
Compare standards... 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?
![Page 37: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/37.jpg)
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…)?
![Page 38: Carrying Capacity (CC) and LAC. Recreation Opportunity Spectrum (ROS) Increased use Increased development PrimitiveUrbanSemi- Primitive Non-motor Rural.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649eb25503460f94bb96b7/html5/thumbnails/38.jpg)
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
