BLM OR Prescribed Fire Treatments Polygon

Frequently-asked questions:


What does this data set describe?

Title:
BLM OR Prescribed Fire Treatments Polygon

Abstract:
BURN_POLY: This dataset represents completed burn land treatments on BLM managed lands in the states of Oregon and Washington. Burn treatments are prescribed burning of wildland fuels in either their natural or modified state, and under specified environmental conditions.

Supplemental information:
Treatments are human alterations to the landscape for the purpose of natural resource management, including use, enhancement, and protection. A treatment creates something new; it creates a new physical entity on the landscape. This distinguishes treatments from attributes or information about treatments. Treatments are areas (polygons), zones of alteration.

    SHAPE
    Feature geometry. (Source: ESRI)
                      

    Coordinates defining the features.

    TRT_ID
    Unique number identifier for the treatment entity.  Multiple "units" of a treatment are given unique TRT_IDs and TRT_ID is unique across all treatment feature classes.  Multiple units or phases of a treatment project are tied together by TRT_NAME, PLANID, NFPORS_PROJID or CONTRACTID as applicable. (Source: BLM)
                      

    TRT_NAME
    Free text name that identifies the treatment entity, preferably with a place reference and treatment type reference.  The name is one-to-one with TRT_ID and the two together provide more reliable identification as long as neither is changed.  Naming conventions need to be standardized by programs and/or offices and enforced in order to avoid confusion and loss of information. (Source: BLM)
                      

    PROJ_NAME
    District-assigned name for a project that encompasses several treatment types and/or treatment units.  It is not the same as the plan or project authorizing the action (PLANID) and there may be many PROJ_NAME for one PLANID. (Source: BLM)

    BLM_ORG_CD
    Combination of the BLM "State" and Field Office which has administrative responsibility for the treatment.  The OR/WA BLM may have administrative responsibility over some area that is physically located in Nevada, Idaho, and California, and vice versa.  Similarly, the treatment may cross Resource Area or District boundaries and the administrative responsibility is assigned to one or the other.  The unit can be identified only to the district or even state level. (Source: BLM)

    TRT_ACRES
    These are actual acres treated or estimated acres proposed for treatment.  Not derived from GIS but can be set to GIS_ACRES, if the entire polygon is considered treated. The TRT_ACRES may be substantially less than the total polygon acres, particularly for CHEM_POLY where treated acres (TRT_ACRES) is calculated as total gallons applied (GAL_MIX_AP) divided by MIX_RATE.

    TRT_MONI
    Result as determined from post treatment inspection.  Questions asked will be different for different treatment types.  For prescribed burn (BURN), these might include: 1.	Was consumption of the targeted fuels inadequate, adequate, or excessive? 2.	Were targeted mortality levels inadequate, adequate, or excessive? 3.	Was soil heating acceptable or unacceptable? 4.	Did any unacceptable damage to non-targeted resources or  resource values occur?  For chemical treatment of weeds (CHEM) the question might be "Are there any weeds left?"  For exclosures (PROT), the question might be whether the targeted animals were effectively excluded.  For seedings (REVEG), the questions might include: 1.	What was the germination percentage? 2.	What percent survived 1 year? 3.	What was the coverage? (Source: BLM)

    ACCURACY_FT
    How close, in feet, the spatial GIS depiction is to the actual location on the ground.  There are several factors to consider in GIS error: scale and accuracy of map-based sources, accuracy of Global Positioning System (GPS) equipment, and the skill level of the data manipulators.  A value of "0" indicates no entry was made.  This is the correct value when the COORD_SRC is another GIS theme (Digital Line Graphs (DLG), Geographic Coordinate Database (GCD), Digital Elevation Model (DEM)) because the accuracy is determined by that theme.  However, if COORD_SRC is MAP (digitized from a paper map) or GPS, a value of "0" indicates a missing value that should be filled in either with a non-zero number or "-1."  A value of "-1" indicates that the accuracy is unknown and no reliable estimate can be made. (Source: BLM)

How was the data set created?

  1. Where did the data come from?

  2. What changes have been made?

    Date: unknown (change 1 of 1)
    Legacy data may be introduced to the dataset by manuscripting on maps and digitizing, GPS, on-screen digitizing using a DOQ or DRG backdrop, duplicating lines from ownership, roads or stream layers, or a combination of these. Treatment boundaries that are based on identifiable physical features such as roads, ridgelines, streams, or on ownership changes should utilize those source line features to illustrate the cartographic relationship. New treatment polygons and edits of existing polygons will be added and noted by district staff.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Many features were imported from the legacy data and the attributes are very incomplete. However, newer features will have more complete information and over time the dataset will become more accurate.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Treatments are dynamic themes that are subject to frequent edits and changes.

  5. How consistent are the relationships among the observations, including topology?
