Title: Landscape Assessment Methods


1
Landscape Assessment Methods
  • National Interagency Fuels Technology Team

2
Lesson Objectives
  • Integrated assessment process to achieve national
    and local objectives
  • Integration of measures of fuels fire behavior,
    Fire Regime Condition Class (FRCC), other
    values
  • Strategies steps for Strategic Prioritization
    Of Treatments (SPOT)
  • LANDFIRE status applications

3
Common National Objectives
  • reduce large fire threat and cost
  • reduce risk to the wildland urban interface
  • conserve heritage resources
  • improve forest rangeland health
    (sustainability)
  • conserve native species improve habitats
  • reduce risks to air watersheds

4
Socio-ecological Landscapes
Ability to achieve these diverse
objectives is dependent on understanding and
managing multiple interacting regimes
Landscape management is about understanding
relationships between human land use and
environment across various scales of land and
different periods of time.

reduce large fire threat cost
  • Healthy Forest Restoration Act
  • National Fire Plan
  • Cohesive Strategies for USDA Interior
  • GAO Reports
  • ..

Recent Fire Seasons (Entire U.S.)
  • 2000 8.5 million acres 1.3 billion
  • 2001 3.5 million acres 0.9 billion
  • 2002 7.0 million acres 1.6 billion
  • 2003 5.0 million acres 1.3 billion
  • 2004 7.7 million acres 0.9 billion

9
reduce risk to wildland urban interface (WUI)
  • Adjacent wildland fuels
  • Defensible space
  • Prevention of unwanted fires
  • ..

10
Shifting Demographics
11
conserve heritage resources
  • Use of fire in past land use
  • Past uses of native plants
  • Manage fire use to conserve heritage resources
  • Risk to heritage resources from uncharacteristic
    fuels fire
  • Antiquities Act
  • Historic Preservation Act

12
conserve heritage resources
13
Why?
forest rangeland health (sustainability)
  • Healthy Forest Restoration Act
  • Other Land and Resource Management Laws
  • Sustainability sustain the productivity
    diversity of management options values
  • Healthy Forests Rangelands resilient to
    disturbance
  • Characteristic Conditions Disturbances within
    the range of species adaptations
  • Fire Regime Condition Class 1 one relatively
    coarse measure

14
How?
  • Representing natural, native systems by using HRV
  • As a baseline reference, not as
  • a management goal
  • Where possible, manage within HRV
  • composition mimic disturbance effects
  • Provides best fit for sustainability and
  • coarse-filter conservation

15
Representing natural, native habitats
disturbances
  • through use of
  • management
  • tools

16
Healthy Forest Rangelands
fire use
prescribed fire
suppression strategies
other resource activities
17
Measured By
  • Fire Regime Condition Class (FRCC)

18
conserving native species habitats
  • keeping all the pieces
  • Value of fish, wildlife, and plants to people
  • Coarse-filter conservation of characteristic
    kinds, amounts, and patterns of habitats
  • Endangered Species Act
  • ..

21
conserving native species habitats
  • Similar terms and concepts between native species
    conservation and healthy forests rangelands
  • Many times there appears to be conflict
  • Most conflict appears to be perceived
    (philosophical) as opposed to real
  • Most conflicts can be resolved with spatial and
    temporal options

22
reduce risks to air watersheds
  • Smoke is often seen as a limiting issue
  • Most concerns with fire use smoke can be resolved
    with spatial and temporal options
  • Inevitability of wildfire with high volumes of
    smoke at vulnerable times is apparent
  • Coarse-filter for soil conservation
  • Soils developed in sync with characteristic
    conditions disturbance regime
  • Clean Water Act
  • Clean Air Act
  • .

25
Assessment Measures
  • Fire Regime Condition Class (FRCC)
  • Forest Rangeland Health (Sustainability)
  • Coarse-filter measure of native habitats
  • Correlated measure of watershed
  • Fuels Fire Behavior Assessment
  • Currently may or may not be assessed
  • FRCC often used as a proxy
  • Many other measures ..

26
Why?
Fuels Fire Behavior Assessment
  • Direct hazard of large fire threat
  • Direct hazard to WUI
  • Hazard or benefit to resource values
  • Measure of fire use opportunity
  • Different measure/scale than FRCC

27
Carl Skinner, PSW
28
  • Key factors in treatment design
  • Fire behavior objectives scaled stick to stick
  • Protection assets (both social resource) that
    are mobile are less constraining than assets that
    are fixed in place
  • FRCC objectives scaled to composition of
    shifting mosaic within the landscape

29
Stylized Landscape Treatment Patterns
  • Very effective at
  • slowing fire from
  • single direction
  • Impractical on
  • real landscapes
  • Insensitive to
  • resources
  • constraints
  • Ineffective at
  • slowing fire from
  • any direction
  • Flexible for variable
  • landscapes and
  • constraints
  • Effective at slowing
  • fire spread from
  • multiple directions
  • Flexible for variable
  • landscapes and
  • constraints

Absolute Fire Behavior Class
31
Why?
  • Integrate
  • Strategize
  • Prioritize

32
Being Strategic
  • Science Art of ..
  • employing the timing and location ..
  • of tactical resources ..
  • based on intelligence data predictions ..
  • to maximize support to ..
  • achieve integrated collaborative objectives ..
  • under advantageous conditions.

Achieving objectives Success
33
Strategic Planning
  • When do you need a strategy?
  • When dealing with more than one factor where want
    to change condition/outcome
  • When dealing with one or more factors that have
    uncontrollable outcomes

34
Strategic Principles
  • Success depends on
  • Accounting for interaction of factors
  • Scale temporal/space tactic effectively
  • Decisiveness in deploying tactics w/in time to
    achieve spatial outcome
  • Availability/effectiveness of tactical resources

35
Evaluating Strategies
36
Evaluating Strategies
37
  • Integrate
  • Strategize
  • Prioritize

What do these mean in an assessment environment?
38
Being Strategic
  • Principle - account for factor interaction
  • Identify integrated/collaborative objectives
  • Integrated
  • to form, coordinate, or blend into a functioning
    or unified whole
  • to end the segregation of and bring into equal
    membership
  • To incorporate into a larger unit (national
    policies, budget, L/R Mgt Plans)

39
Integrate Collaborate
  • to work jointly with others in an endeavor

Why?
  • Increase tactical resources
  • Maximize support
  • Increase advantageous position

40
Integration Scales, Components, Landscape
Strategies
  • Scale of component integration
  • Components
  • Landscape strategies for integration
  • Stepwise process for assessment

41
Scale Differences Flexibility
  • Improving condition (FRCC) gt 5 x large fire
    scale gt 20 x urban interface scale gt 20 x
    resource conflicts scale

---------- FRCC Scale ------------
Resource conflicts lt 1/20th FRCC
Interface scale lt 1/20th FRCC
Large fire scale lt 1/5th FRCC

ISSUES ENCOUNTERED
  • Difference between RA FRCC and Map Tool Results
    because of disected subsections
  • Limit analysis area in Map Tool to complete
    Reporting Units (i.e., subsections/HUCs)
  • Restrict FRCC calculations in Map Tool to minimum
    dynamic area for individual PNVGs. Expert
    feedback LF HRV analysis
  • Develop one-page fact sheet on how scale affects
    FRCC calculations

64
LANDFIRE when to use not use?
  • LANDFIRE National national, region/state,
    subregional
  • Subregional for example prioritize identify
    options for District, Field Office, Park, and
    Monument annual program of work integrated IA
    LMP or FMP roll-up
  • Project for example NEPA, burn plan, etc.
  • If no other data provides starting point for
    project or incident management integrate as much
    local data/knowledge as possible

65
