Analysis, GIS

A method of analysis of data that includes the geographic location of that data

Aspect

Cable yarding

A method to move timber logs from the stump to the truck loading site (landing) that utilizes a system of overhead cables to move the partially or fully suspended logs

Canopy, closed

As used in this plan and as in the guidelines for Fire Regime Condition Class determinations, a vegetation-fuel class characteristic based on upper layer vegetation canopy cover with relatively little space between vegetation tops. Generally closed canopies are those with 40% or more closure.

Canopy, open

As used in this plan and as in the guidelines for Fire Regime Condition Class determinations, a vegetation-fuel class characteristic based on upper layer vegetation canopy cover with relatively more space between vegetation tops. Generally open canopies are those with closure of less than 40%.

Catron County Citizen’s Group

A coalition of interested parties which evolved during the 1990's to address mutual concerns regarding the County, especially as relates to use and protection of the natural resources of Catron County.

Cells

GIS analysis and in particular modeling in GIS uses cells as a means to efficiently process large amounts of data. Cells can be different sizes, 30 x 30 meter cells being used in this plan. A cell is assigned appropriate values to represent information about the location or as determined in a analysis model.

Collaborative Forest Restoration Project

(CFRP) A New Mexico program founded on the principle of collaborative management to address forest resource conflicts. The program provides costshare grants for experimental forest restoration projects executed through a collaboration of diverse interests. CFRP is the first legislated program to require collaboration as a way of doing business.

Commercial treatment

Meets prescribed objectives in a monetarily profitable manner through removal of woody material to meet fuels management objectives.

Community Wildfire Protection Plan

A plan developed by a community in an area at-risk from wildland fire; a collaborative product involving interested parties, local government, local fire fighting agencies, the state agency which oversees forest management and federal land management agencies. A valid CWPP has two objectives.

Identify and prioritize the surrounding area, both federal and nonfederal lands, for hazardous fuels reduction treatments, as well as recommending methods for achieving hazardous fuels reductions.

Recommend measures for reducing structural ignitability through out the at-risk community.

Computer model

Fuel Hazard (Fire) Threat

The threat of unacceptable damage by wildfire to community and land resources, uses and values. Four factors were used in determining fire threat: Potential natural vegetative cover type, structural stage, aspect and steepness of slope resulting in a relative index of fire threat. The index is useful only as a comparison between locations and is not meant to be a measure of such commonly used terms as flame length and rate of spread which would require more specific data and modeling such as would be done for project level analysis.

Structural state

Five structural or successional vegetation development stages are used in this analysis: Early, Mid-closed, Mid-open, Late-closed and Late-open. For purposes of determining fire threat in this analysis, the closed stages are combined into one stage and the open stages are combined into one stage.

Structural state, mid development:

The vegetation stage in mid successional or immature condition. In forests of ponderosa pine and similar "sawtimber" species, this is commonly spoken of as poletimber and immature sawtimber.

Structural state, closed/open

A vegetation-fuel class characteristic based on upper layer vegetation canopy cover. Typically closed is canopy closure greater than 40% in forest, woodland and herbaceous vegetation and greater than 15% in shrub vegetation.

Structural state, early

 

Early: areas that are open, very sparsely stocked in trees/shrubs or in young trees (seedlings saplings). This stage is also called post-replacement, meaning the condition existing after an area or "stand" replacement disturbance such as a wildfire. Canopy closure is generally less than 10% for trees and less than 5% for shrubs.

Structural state, late development:

The vegetation stage in late successional or mature condition. In forest of ponderosa pine and similar "sawtimber" species, this is commonly spoken of as mature and overmature sawtimber.

Subdivisions

Threat, fire

See Fuel hazard
