Description
Abstract

This grid represents Condition Class.
Condition Class is an expression of the degree of departure of
the current vegetation and fuel condition from the historic
(pre-settlement) natural fire regime. This departure results
in changes to vegetation composition and structure, fuel composition,
fire frequency and behavior, disturbance agents, and other ecosystem
processes. Condition Class is based on the relationship of current
expected fires to historic fire regimes and is a measure of the
relative risk of losing key ecosystem elements and processes should a
fire occur. Condition Class 1 indicates fire regimes within or near
historical ranges, with low risk of losing key ecosystem components.
Condition Class 2 indicates a moderate departure from historical fire
regimes (such as where fire frequencies have changed by one or more
return interval), and a moderate risk of loss of key ecosystem
components. Condition Class 3 is characterized by fire regimes
substantially altered from their natural historical range (such
as where fire frequencies have changed from natural frequencies
by multiple return intervals), and the risk of losing key ecosystem
components is high.

Quoted from: http://frap.cdf.ca.gov/data/frapgisdata/output/cafrcc.txt
Wildfire can cause serious and long-lasting damage to ecosystems.
Following National Fire Plan concepts, FRAP has utilized data
specific to California to describe ecosystems and fire-related
metrics used in other analyses to define and describe fire-related
risks to ecosystems. Fundamental to this idea is that current expected
fires are compared to historic fire regimes with respect to fire
frequency, size and patchiness, and effects on key ecosystem elements
and processes. Thus, these classes are then assigned based on current
vegetation type and structure, an understanding of its pre-settlement
fire regime, and current conditions regarding expected fire frequency
and potential fire behavior. As a result of these efforts, ?Condition
Classes? were defined as the ?relative risk of losing key components
that define an ecosystem (Hardy et al., 2001).

Purpose

The California portion of this data was developed by The California
Dept. of Forestry and Fire Protection, Fire and Resource Assessment
Program and the USDA Forest Service to illustrate the degree of
departure of the current vegetation and fuel condition from the
historic (pre-settlement) natural fire regime.

The original grid cafrcc03_2 was created by California Department
of Forestry and Fire Protection (CDF FRAP) for the state of California.
In 2004, additional areas were added by USFS Remote Sensing Lab with
the assistance of CDF FRAP to encompass all of USFS Region 5. These
areas include: the eastern portion of Lake Tahoe Basin, the Region 5
portion of Inyo National Forest, and the Oregon portion of Klamath
National Forest. (see Procedures_Used)

Supplemental_Information
Procedures_Used

Below is an outline of the requirements and the process of
Developing the Condition Class Grid

Required Datasets
Required AMLs
Explanation of Required Lookup Tables / Crosswalks
Part A: Create Fuel Model Grid
Part B: Create the Slope Grid
Part C: Create the Ladder & Crown Grid
Part D: Create Fuels Rank Grid.
Part E: Create Planning Belt Grid
Part F: Create the Fire Rotation Rank Grid
Part G: Create the Vegetation Grid
Part H: Combine Fuels Rank Grid, Fire Rotation Rank Grid, and
Vegetation Grid
Part I: Create the Condition Class Grid

Required Datasets
1. Vegetation - with whrtype, whrsize, & whrdensity
2. DEM or Elevation Grid

Required AMLs
1. fbps_rank.aml - uses the fuel grid, crown grid, ladder grid, slope
grid, and the Surface Rank lookup table (surf_rank.lut), & creates
surf.lut and the fuels rank grid.
2. itemmatch.aml - used by fbps_rank.aml

Required Documents
1. Using Fire Rotation to Characterize Wildfire Risk in California,
March 2, 2002 by James Spero et al. The Strata Information Table
starting on page 6, and the Pooled Strata Table on page 9 are relevant
tables.
2. Crosswalks.txt ? provides Fuel Model values for Sequoia and Inyo
areas.

Explanation of Required Lookup Tables / Crosswalks

1. Fuel Model / FBPS Crosswalk
Incomplete & inconsistent information was available for this crosswalk
at the time of writing.

The Fuel Model Crosswalks are to determine Fuel Model values, which
are also represented in provided information as Fire Behavior
Prediction System (FBPS) values. A 3 page text document
(Crosswalks.txt) was provided from which to determine Fuel Model
values for the Inyo and Sequoia using vegtype.

For determining Fuel Model / FBPS values for Lake Tahoe Basin and
Toiyabe areas, ltbtoixwalk.dbf was provided. This crosswalk uses
vegtype, size, and density. Since there were combinations found that
were not present in ltbtoixwalk.dbf, additional Fuel Model values
were provided by Bernie Bahrow & Klaus Barber and the resulting
Crosswalk saved as LTB_TOIxwalk.dbf.

For the Klamath, ct4_eveg6.xwalk was provided to assist in determining
FBPS values using a combination of vegtype, size, density, size2,
and density2.

Inconsistencies (?)
Inyo = INF_FBPSxwalk.dbf (considers only vegtype)
Lake Tahoe Basin / Toiyabe = LTB_FBPSxwalk.dbf (considers vegtype,
size, & density)
Klamath = ct4_eveg6.xwalk (considers vegtype, size, density, size2,
& density2)

2. Crown & Ladder Crosswalk
These are lookup tables that determine Crown & Ladder values from
Fuel Model values, which are represented in the lookup tables as
FBPS_BURN.

Inyo - bdulad_crn.lut
Klamath - skulad_crn.lut
Lake Tahoe Basin - neulad_crn.lut

3. Surface Fuels Rank Crosswalk
This lookup table is used in determining Surface Fuels Rank. It's
called surf_rank.lut and is used in fbps_rank.aml in creating the
Fuels Rank Grid.

4. Planning Belt Crosswalks.
These are lookup tables that determine Planning Belt ID (PB_ID) from
Fire Behavior Prediction System (FBPS) values. Each region has unique
values.

Lake Tahoe Basin / Toiyabe = ltb_pbid.lut
Klamath = knf_pbid.lut
Inyo = inf_pbid.lut

5. Fire Rotation Crosswalks
These are lookup tables that determine Fire Rotation values from
PB_ID values. These lookup tables are derived from the Strata
Information Table in ?Using Fire Rotation to Characterize Wildfire
Risk in California?, starting on page 6. To create a Fire Rotation
Crosswalk, locate the correct bioregion and determine ownership, and
create a table of the PB_ID values and their matching FR (Fire
Rotation) values. Fire Rotation Crosswalks have been created for
the following bioregions:

Forest Bioregion Look-up Table
Lake Tahoe Basin Sierra fr_sierra.lut
Toiyabe Mojave fr_mojave.lut
Inyo Mojave fr_mojave.lut
Klamath North Coast / Klamath fr_ncklam.lut

6. Condition Class Crosswalk
This is a lookup table that determines Condition Class from the
combined values of whrtype, whrsize, whrdensity, fuel rank, and
fire rotation rank. All regions use con_class0304.lut

Part A: Create Fuel Model / FBPS Grid

This grid will consider vegtype, size, and density. Since the
vegetation coverage contains separate size and density items for
conifer & hardwood, the relative values should be considered.
Datasets Needed: Vegetation coverage
Lookup Tables Needed: The Fuel Model Crosswalk

Vegetation Coverage Preparation
Currently, relevant items in the vegetation coverage are some
combination of vegtype, size, density, size2, & density2. Leading
spaces and odd characters should be removed. Where there is a space
for density or size, calc that item = ?0?. Concatenate these items
in an order consistent with the order to be concatenated in the Fuel
Model Crosswalk.

Fuel Model Crosswalk Preparation

The existing Fuel Model Crosswalks as described above are to be used
for the areas mentioned, but for other areas there are no known sources
to assist in determining Fuel Model (or FBPS) values from vegtype or
a combination of vegtype and the other items mentioned above.

Ensure that there is a field containing concatenated items that matches
the order of concatenation in the vegetation coverage.

Join the FBPS Crosswalk to the vegetation coverage on the concatenated
item so that each vegetation polygon also has an FBPS value.

Create a new grid using the FBPS item as the value item. This is the
FBPS grid.

Part B: Create the Slope Grid

Datasets Needed: DEM

1. Generate a slope grid in percent.

2. Add an item called ?slope? in the slope grid and reclassify the
values according to:

0 10: 0
10 25: 1
25 40: 2
40 55: 3
55 75: 4
75 999: 5

Part C: Create the Crown & Ladder Datasets

Datasets Needed: FBPS Grid
Lookup Tables Needed: Crown & Ladder Crosswalk

1. Join the Crown & Ladder Crosswalk to the FBPS grid on the FBPS and
FBPS_BURN items.

2. Create two new grids using the crown and ladder items as the value
item. These are the Crown Grid and the Ladder Grid.

Part D: Create Fuels Rank Dataset

Datasets Needed: Crown Grid, Ladder Grid, FBPS Grid, Slope Grid
Lookup Tables Needed: surf_rank.lut
AMLs needed:
1. fbps_rank.aml - uses the fuel grid, crown grid, ladder grid, slope
grid, and the Surface Rank lookup table (surf_rank.lut), & creates
surf.lut and the fuels rank grid.
2. itemmatch.aml - used by fbps_rank.aml

1. Ensure all necessary inputs (grids, amls, & lookup table) are in
the same directory. Run fbps_rank.aml on the 4 input grids & provide
a name for the output grid. The output grid will have an item called
?sumrank?.

2. Create a new grid using the ?sumrank? item as the value item. This
is the Fuels Rank Grid.

Part E: Create Planning Belt Grid

Datasets Needed: Fuels Grid, DEM or Elevation Grid
Lookup Tables Needed: Planning Belt Crosswalk to determine Planning
Belt ID (PB_ID) from Fire Behavior Prediction System (FBPS) values

1. Join the Planning Belt Crosswalk to the Fuels Rank Grid based on
the FBPS item.

2. Create a new grid using the PB_ID integer item as the value item.
This is the interim Planning Belt Grid.

Considering Alpine Areas ? Steps 3 through 7
These step are necessary where there are areas above 6500 feet, and
there exists a PB_ID value of ?A? in the Strata Information Table on
page 6 of Using Fire Rotation to Characterize Wildfire Risk in
California, March 2, 2002 by James Spero et al.
Areas above 6500 ft are considered Alpine and will be reclassified
as Alpine regardless of what the initial PB_ID value is in the interim
Planning Belt Grid. In other words the Alpine areas will be combined
with the interim Planning Belt Grid so that the PB_ID value for Alpine
areas will supercede existing PB_ID values. To convert metres to feet,
multiply metres by 3.2808

3. From the elevation grid, reselect records with elevation values at
6500 ft or more and assign those a single integer value corresponding
to ?A? in the Planning Belt Crosswalk. For example, in the ltb_pbid.lut
, where the pb_id value is ?A?, the pb_int value is 6. Assign 6 to
these Alpine areas.

4. Create a new grid of just those cells with the Alpine designation
and assign a null value to any cells not Alpine. The null value is
important so that the non-alpine areas do not overwrite the interim
Planning Belt Grid. This is the Alpine Grid.

5. Merge the Alpine Grid with the interim Planning Belt Grid so that
the ?A? areas override values in the interim Planning Belt Grid.
The merged output grid is the Planning Belt Grid

6. Assign the PB_ID value of the alpine areas (from the Alpine Grid)
in the Planning Belt Grid an ?A?.

Part F: Create the Fire Rotation Rank Grid

Datasets Needed: Planning Belt Grid
Lookup Tables Needed: Fire Rotation Crosswalk to determine Fire
Rotation from Planning Belt ID values.
Refer to on page 4 of. Using Fire Rotation to Characterize Wildfire
Risk in California, March 2, 2002 by James Spero et al. for a brief
explanation of how Fire Rotation relates to Rank.

1. Join the Fire Rotation Crosswalk to the Planning Belt Grid on the
PB_ID value.

2. Create a new grid using the Fire Rotation (FR) values. This is the
Fire Rotation Grid.

3. Add a new item to the Fire Rotation Grid called rank and populate
is according to the following:

Rank FR Value
1 gt 300
2 gt 100 & lt or eq 300
3 lt or eq 100

4. Create a new grid using the rank value. This is the Fire Rotation
Interval Grid.

Part G: Create the Vegetation Grid

Datasets Needed: vegetation coverage

A grid will be created that will reflect a unique combination of
whrtype, whrsize, and whrdensity.
1. Create a grid using the internal polygon number (coverage#) as
the value item. Save both this Vegetation Grid and the coverage used
to create it.

Part H: Combine Fuels Rank Grid, Fire Rotation Interval Grid, and
Vegetation Grid and Create the Interim Condition Class Grid

Datasets Needed: Fuels Rank Grid, Fire Rotation Interval Grid,
Vegetation Grid, prepared vegetation coverage
Lookup Tables Needed: con_class0304.lut

1. Combine the 3 input grids listed above. This is the interim
Condition Class Grid. The items representing Fuels Rank and Fire
Rotation Interval should have widths of 2 and 1 respectively.

2. Join the items in the dissolved vegetation coverage to the interim
Condition Class Grid using the vegetation item in the grid, and the
coverage# number, as the joinitem.

3. Override the Fuels Rank values where WHRTYPE is non-fuel. For
records where whrtype is any of the following:
WAT
MAR
BAR
LAC
EST
AGR

. . .calculate the Fuel Rank value to ?-1?.

Part I: Create the Condition Class Grid
Datasets Needed: interim Condition Class Grid
Lookup Tables Needed: Condition Class Crosswalk

1. In the interim Condition Class Grid, concatenate the five Relevant
Items. The order and widths of concatenated items must match the order
and widths of the concatenated items in con_class0304.lut

2. Join the Condition Class Crosswalk to the interim Condition Class
Grid based on the concatenated items.

3. Create a new grid using the con_class item in the interim Condition
Class Grid. This is the Condition Class Grid.
