Abstract:
The LANDFIRE fuel data describe the composition and characteristics of both surface fuel and canopy fuel. Specific products include fire behavior fuel models, canopy bulk density (CBD), canopy base height (CBH), canopy cover (CC), canopy height (CH), and fuel loading models (FLMs). These data may be implemented within models to predict the behavior and effects of wildland fire. These data are useful for strategic fuel treatment prioritization and tactical assessment of fire behavior and effects. DATA SUMMARY: Canopy height (CH) describes the average height of the top of the canopy for a stand. A spatially-explicit map of canopy height supplies information for fire behavior models such as FARSITE (Finney 1998) to determine the starting point for embers in the spotting model, calculate wind reductions, and compute the volume of crown fuels. In FARSITE, canopy characteristics are used to compute shading for fuel moisture calculations, wind reduction factors, spotting distances, crown fuel volume, spread characteristics of crown fires and incorporate the effects of ladder fuels for transitions from a surface to crown fire. Canopy characteristics refer to the tree canopy. Where there are tree canopies, i.e. existing vegetation types that are forest and woodland, LANDFIRE has attributed the grid with canopy characteristics with some exceptions. There will be no canopy characteristics in fuel types where the tree canopy is considered a part of the surface fuel and the surface fire behavior fuel model is chosen as such. This is because LANDFIRE assumes the potential burnable biomass in the tree canopy has been accounted for in the surface fuel model parameters. For example, young or short conifer stands where the trees are represented by a shrub type fuel model will not have canopy characteristics. CH is derived from Existing Vegetation Height (EVH) using the Landfire Total Fuel Change (LFTFC) ArcGIS toolbar. Forested EVH values are reclassified from the five Landfire EVH codes to represent the midpoint of the classification. CH values are represented in meters times 10 starting with 25 and ending at 500. Where EVH is not forested or the tree height is considered to be part of the surface fuel CH receives a value of 0. Certain types of agriculture that a deemed burnable get a value added by LFTFC based on region and type of vegetation. Field plot data contributed either directly or indirectly to this LANDFIRE National data product. Go to <http://landfire.gov/participate_refdata_sub.php> for more information regarding contributors of field plot data. LANDFIRE 2014 (lf_1.4.0) and used LANDFIRE 2012 (lf_1.3.0) data as a launching point to incorporate disturbance and its severity, both managed and natural, which occurred on the landscape after 2012. Specific examples of disturbance are: fire, vegetation management, wind, and insect and disease. Disturbance data used in the updating is the result of several efforts that include data derived in part from remotely sensed land change methods, Monitoring Trends in Burn Severity (MTBS), and the LANDFIRE events data call. Vegetation growth was modeled where disturbance occurred.
Purpose:
LANDFIRE data products are designed to facilitate national- and regional-level strategic planning and reporting of management activities. Data products are created at a 30-meter grid spatial resolution raster data set; however, the applicability of data products varies by location and specific use. Principal purposes of the data products include providing, 1) national-level, landscape-scale geospatial products to support fire and fuels management planning, and, 2) consistent fuels data to support fire planning, analysis, and budgeting to evaluate fire management alternatives. Users are advised to evaluate the data carefully for their applications.
Supplemental_Information:
Units are meters * 10. The NoData value in this image is -9999. To retrieve the actual canopy height for a given pixel, simply multiply the value by 0.1 or divide by 10. Classes (midpoints): -9999 = NoData 0 = Non-forested vegetation 25 = 0 < CH < 5 meters 75 = 5 <= CH < 10 meters 175 = 10 <= CH < 25 meters 375 = 25 <= CH < 50 meters 500 = CH >= 50 meters

Use_Constraints:
Although LANDFIRE products are delivered as 30-meter pixels, they should not be used at the individual pixel level or on small groups of pixels. LANDFIRE products were designed to support 1) national (all states) strategic planning, 2) regional (single large states or groups of smaller states), and 3) strategic/tactical planning for large sub-regional landscapes and Fire Management Units (FMUs) (such as significant portions of states or multiple federal administrative entities). The applicability of LANDFIRE products to support fire and land management planning on smaller areas will vary by product, location, and specific use. Further investigation by local and regional experts should be conducted to inform decisions regarding local applicability. However, it is the responsibility of the local user, using LANDFIRE metadata and local knowledge, to determine if and/or how LANDFIRE can be used for particular areas of interest. LANDFIRE products are not intended to replace local products, but rather serve as a back-up by providing wall-to-wall cross-boundary products. It is the responsibility of the user to be familiar with the value, assumptions, and limitations of LANDFIRE products. Managers and planners must evaluate LANDFIRE data according to the scale and requirements specific to their needs.

Process_Description:
LF_1.2.0 and LF_1.1.0 Existing Vegetation Height: The existing vegetation height (EVH) data layer is an important input to LANDFIRE mapping efforts. Canopy height is generated separately for tree, shrub and herbaceous cover life forms using training data and a series of geospatial data layers. Plots from the Forest Inventory and Analysis (FIA) program of USDA Forest Service (<http://fia.fs.fed.us/>) were used as the training data for tree canopy height mapping. EVH is determined by the average height weighted by species cover and based on existing vegetation type (EVT) life-form assignments. Dominant life-form height of each plot is then binned as follows: (A) Tree classes; 0-5 m, 5-10 m, 10-25 m, 25-50 m, and greater than 50 m, (B) Shrub classes; 0-0.5 m, 0.5-1.0 m, 1.0-3.0 m, greater than 3.0 m, (C) Herbaceous vegetation classes; 0-0.5 m; 0.5-1.0 m, greater than 1 m. Go to <https://www.landfire.gov/participate_refdata_sub.php> for more information regarding contributors of field plot data. Decision tree models using field reference data and Landsat imagery, digital elevation model data, and biophysical gradient data, are then developed separately for each of the three life forms using C5 software. Life-form specific cross-validation error matrices are generated during this process to assess levels of accuracy of the models. Decision tree relationships are then used to generate life-form specific height class spatial data layers, which are later merged into a single composite height data layer. The final EVH layer is evaluated and rectified through a series of QA/QC measures to ensure that the life-form of the cover code matched the life-form of the existing vegetation type.
