- Description:
- Abstract:
- This data publication contains approximately 44.3 million polygons derived from multi-scale object-oriented image analysis attributed with climatic, topographic, soil, vegetation, and disturbance variables. The polygons provide continuous coverage for the entire state of Idaho, USA. Additionally, this publication contains the parameters for lasso logistic regression models generated to predict the probability of plant species occurrence using the variables attributed to each polygon.
- Purpose:
- To estimate probability of occurrence for 20 ungulate forage species across Idaho and provide a state-wide unit of analysis for other plant species distribution analyses.

- Data_Quality_Information:
- Logical_Consistency_Report:
- All data were projected into NAD83 Idaho Transverse Mercator. All polygons were checked for and cleared of topology overlap errors.
- Completeness_Report:
- In general, the data provides wall-to-wall coverage of Idaho, USA. However, we have observed that a few polygons are missing from the dataset. Such omissions appear to be correlated with large, homogenous, and non-vegetated surfaces such as roads and lava flows. The exact number of polygon omissions is unknown.
Most polygons are attributed with mean and standard deviation of the four NAIP bands (blue, green, red, and near-infrared). However, some NA's were generated when fixing topology overlap errors. The exact number of polygons affected is unknown.
All polygons touching the Idaho border were included in the data. However, many environmental variables were clipped at the Idaho border, so environmental attributes may be representative only of the portion of the polygon within Idaho.

- NAIP imagery was segmented in eCognition Developer 9.2 using a shape value of 0.1 and a compactness value of 0.3. Processing was across Idaho done by USGS 1:100,000 quadrangles. Edge effects between quadrangles were eliminated by selecting segmented polygons with edge effects and re-segmenting the NAIP imagery for those areas to produce continuous segmented polygons across the state, free from artificial lines caused by the 1:100,000 quadrangles. For the sake of memory constraints and processing efficiency, segmented polygons were grouped by USGS 1:24,000 quadrangles across the state.
The resulting polygons contained attributes for mean and standard deviation of each NAIP band.

- Multiple variables were generated from the USGS elevation data in ArcGIS Desktop 10.4. These included elevation (ele), slope (slp), sine of aspect (sasp), cosine of aspect (casp), landscape curvature index (lcv), topographic position index (tpi), topographic wetness index (twi), and solar radiation index (sri).
Elevation was derived directly from the USGS DEM. Slope was calculated using the ArcGIS slope function.
Sine of aspect was calculated using the aspect function in ArcGIS, reclassifying flat areas to NoData, converting to radians, applying sine, multiplying by 10, and converting to integer.
Cosine of aspect was calculated using the aspect function in ArcGIS, reclassifying flat areas to NoData, converting to radians, applying cosine, multiplying by 10, and converting to integer.
Landscape curvature index was calculated using the curvature function in ArcGIS with the standard curvature type and a Z factor of 1.
Topographic position index was calculated in the Land Facet Corridor Designer ArcGIS tool extension using a 'circle' neighborhood shape, with a 21.5m radius, 'cells' as the neighborhood size unit, and leaving the 'setting no data if any no data cells are in the neighborhood' unchecked.
The topographic position index tool is described in:
Jenness, J., B. Brost, and P. Beier. 2013. Land Facet Corridor Designer. https://corridordesign.org
Topographic wetness index was calculated in ArcGIS using the equation: twi = ln(Sca_scaled/Tan_slp), where Fd = flow direction from the ArcGIS flow direction tool in Spatial Analyst
Sca = flow accumulation from the ArcGIS flow accumulation tool in Spatial Analyst (requires Fd)
Slope = slope from the USGS DEM converter to radians
Sca_scaled = (Sca+1)*10
Tan_slp = Con(Slope>0, tan(Slope), 0.001)
Topographic wetness index is defined in:
Moore, I.D., Gessler, P.E., Nielsen, G.A., Petersen, G.A., 1993. Terrain attributes: Estimation methods and scale effects. In: Jakeman, A.J., Beck, M.B., McAleer, M. (Eds.) Modelling Change in Environmental Systems. Wiley, London, pp. 189-214.
Solar radiation index was calculated using the solar radiation function in ArcGIS. The DEM was first divided into 1 degree latitudes. For each latitudinal strip (i.e, 42, 43, 44, etc.), tool inputs were the latitude being processing, '200' for sky size, 'multiple days in a year' for time configuration, '2015' for year, '15 May 2015' for start date, and '31 August 2015' for end date. Output rasters of each latitude were merged to provide a state-wide solar radiation index raster.

Results were labelled accordingly: maximum temperature = maxtp, minimum temperature = mintp, maximum precipitation = maxpr, minimum precipitation = minpr, annual precipitation = tapr.

- NRCS soil data was compiled from both the Soil Survey Geographic database (SSURGO) and the Digital General Soil map (STATSGO2). SSURGO and STATSGO2 vector data were converted into raster grids and combined using 'Mosaic to new raster" in ArcGIS, with an overlap priority setting for SSURGO data. This process was conducted for cation-exchange capacity (cec), percent clay (clay), percent sand (sand), percent silt (silt), pH (ph), available water supply (aws), depth to any restrictive layer (d2r), percent calcium carbonate (caco3), and percent organic matter (om).

- Each environmental variable was summarized for each polygon using the Zonal statistics as table tool in ArcGIS (ran using the arcpy python module) on each 1:24,000 quadrangle. Continuous variables (ele, sri, maxtp, maxpr, mintp, minpr, tapr, cec, clay, sand, silt, tc, aws, d2r, caco3, and om) were summarized by their mean, while index values (sasp, casp, lcv, tpi, twi, ph, sc, ff, and tsf) were summarized by their mode. The tables were then joined to the segmented polygons.
Additional attributes added to the segmented polygons were 'long', 'lat', 'quad', 'id', and 'shp_area'. Latitude (lat) and longitude (long) were computed in R for each polygon center. Area in square meters of the polygon (shp_area) was calculated in R. Quad indicated which 1:24,000 quadrangle the polygon was mostly contained by. Id is a unique identifier for each polygon in a given quad.
The result was the final set of Idaho habitat patches, indexed by 1:24,000 quadrangle.

- Vegetation survey data were compiled in Microsoft Access to ensure consistency between data sources and naming conventions. If exact coordinates for each line point were not included in the original data, they were calculated in R based on direction, azimuth, and starting coordinates of the transect and added to the Access database.
Once the data was cleaned, .csv tables exported from access were joined with the Idaho habitat patches shapefiles using spatial join in ArcGIS. Using R, the results of the join were summarized to include the number of observations of each target species and the number of total line points for each habitat patch (i.e., polygon), along with the environmental attributes already contained in the Idaho habitat patches shapefiles.
Lasso logistic regression was conducted in R, using the 'glmnet' library. Models were run for 20 forage species using a set of all environmental predictors (distal-proximal) and variables with proximal effects only. Proximal refers to a variable having more direct impact on plant growth and distal, less direct impact. Each model was saved as an .rds file, which can be used to make occurrence predictions for the 20 forage species across any of the Idaho habitat patch shapefiles.
For more details on modelling, see the cross-referenced article, McCarley et al. 2020.
