Detailed Description

This video describes Step 4 and the developing report of the Land Treatment Exploration Tool. In Step 4 the used selects layers to generate spatial overlap statistics with their planned treatment boundary. Summary tables are generated and displayed in the Report tab, where a user can create a PDF Site Characterization Report for their planned treatment boundary. Optionally the user can move to Steps 5 and 6 to include legacy land treatment information in their exported report.

These tutorial videos were created to aid in the use of the Land Treatment Exploration Tool (LTET). These videos guide a user through the main steps of the tool. Each year, public land managers make decisions regarding restoration and rehabilitation actions that influence landscapes and ecosystems. Many of these decisions involve soil and vegetation manipulations, often known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. These treatments were historically planned on a case by case basis with decisions about implementation approaches, methods, and operations derived from personal experience of past successes or failures. Modern adaptive management strategies strive to capture this local knowledge through time, both locally and regionally. In 2017, the U.S. Geological Survey partnered with the Bureau of Land Management to create the Land Treatment Exploration Tool to facilitate adaptive management of land treatments. The Exploration Tool taps into a wealth of information about past treatments in the Land Treatment Digital Library (LTDL), a catalog of information about all known treatments on public lands administered by the BLM in the Western United States.

Welcome to the Land Treatment Exploration Tool tutorial.  Step 4, summarize your proposed treatment area, and the developing report. In step 4 you select layers to summarize within your planned treatment polygon. The list of available layers appears on the left side. By default, climate, soil temperature and moisture regimes, and resistance and resilience are always selected. While ESR Wildfire Project is selected in Step 1, the default selections are also vegetation type, ecological site name, wildfire probability in the sagebrush biome, shrubland fractional components, sage-grouse habitat management areas, ESR Priority Landscapes, and fish and wildlife critical habitat. The layers that are not checked by default can be optionally included by checking the box to the left of each layer name. To include all of them, simply click 'Select all' at the top of this step. For example, I will output all of the available summary tables. If you want to view the layers spatially to determine if you want to include them, you can click 'View layers you can turn on and off' at the bottom. This will direct you to the Planning Map and Layers/Legend tab. Once your selection is made, click Add to Report at the bottom of this step. The Exploration Tool will then toggle to the Report tab. It will first show you an informative message, titled 'Welcome to your developing report.' You can close this message by clicking the 'x' in the upper right hand corner of the pop-up. The report tab starts off the developing report by showing the project name and treatments, and a map at the top.  The map in this section will define the zoom scale of subsequent maps exported in the report. Under the map we have included the acres, square kilometers, and the BLM field and district office of the planned treatment polygon. Below this are the summary tables for the layers that were selected from step 4. Continuous layers, such as elevation, precipitation and temperature, will be summarized across the treatment area with a mean, range, and standard deviation. Categorical layers, such as soil temperature/moisture regimes, conifer invasion risk, and vegetation type, will have the categories intersecting the treatment area along with the percentage and acreage of each intersecting category. Under each summary table is a link to view the map of the data represented in the table. Clicking this opens a pop-up window of a map that only displays the layer. I have clicked the link to open the map for LandFire vegetation cover type. This pop-up map has the legend on the left and the map on the right. To close the popup, click the close button on the bottom right. The last tables on the report are cover estimates of plant functional groups. These take the longest to calculate and a Processing message will appear until the data are returned. The first cover table shows modeled annual herbaceous cover as of July 2019.  The columns are the cover amount bins. For this example, the planned polygon had 0-10% annual herbaceous cover on 23. 6% of the area. While you are waiting for the final tables to fill in with data, it's a good time to make use of the annotation box we include to take notes on the summary tables. This annotation box is located right after the summary tables. The last section of the developing report will list the Land Treatment Digital Library Matches that will be queried for and filtered in steps 5 and 6. Once the cover tables are returned, you can view cover estimates for annual herbaceous, bare ground, big sagebrush, herbaceous, sagebrush, and shrub cover. These data are from the National Land Cover Database, and their estimates are circa 2015 to 2016 conditions. Like the prior cover table, the first table has cover bins for each column. This example had 0-10% sagebrush cover on 98% of the polygon. The next table to the right of this shows the average cover value of each bin. For this example, the average cover of sagebrush in the 0-10% category is 2. 25% sagebrush cover. The last two tables provide height estimates for sagebrush and all shrubs.
