<para>This dataset contains two GIS datalayers, one CSV file and an associated R script used to produce figures for the 2017 Wildlands and Woodlands report. The “wedge diagram” data (HF360-01-landcover-data.csv) shows actual percent landcover estimates across New England from 1940 to 2010 and straight-line trends needed between 2010 to 2070 to reach the Wildlands and Woodland vision by 2060. The published diagram can be seen in figure 1 of the 2017 Wildlands and Woodland report.</para> <para>In hf360-03-community-forests.zip, the GIS layer shows towns that contain community forests as determined by the authors of the report.</para> <para>In hf360-04-wildland-woodland-zones.zip, the GIS layer shows Wildland and Woodland Zones as illustrated in the report. It was created by starting with the Wildland and Woodland zones from the 2010 report and adding in areas with high agricultural land use. These types are meant to be conceptual and not prescriptive.</para> </section> <section> <title>Wildlands and Woodlands Report: Foster, D. R., Lambert, K. F., Kittredge, D. B., Donahue, B.

Wedge Diagram Creation Files The files used to make the "wedge diagram" of landcover change over time (Wildland and Woodlands Report, Figure 1) include hf360-01-landcover-data.csv, which contains landcover data and goals, and the associated R script, hf360-02-wedge-diagram-graph.txt. The output file of the R script is a PDF. Users can either use Adobe Illustrator or alter the R script to change the appearance of the labels as desired.

Community Forests Shapefile The zipped file hf360-03-community-forests.zip contains data for New England towns that were determined by Wildland and Woodland researchers to have community forests. Forests highlighted in the Wildland and Woodland report are denoted by a 1 and SiteName is the property name for highlighted town forests.

Wildland and Woodland Zones Shapefile The zipped file hf360-04-wildland-woodland-zones.zip contains data for Wildland and Woodland Zones as shown in the report. This layer was made as a raster format using Model Builder. The process started with the Wildland and Woodland zones from the 2010 report which did not consider agricultural lands. Making this file involved calculating the percent agriculture in the 2011 NLCD landcover for a 6km window across New England with a 500m cell size snapped to the original 2010 Wildland and Woodland Zones (see related dataset, HF359 Natural Land Zones in New England in 2006 from 2010 Wildlands and Woodlands Report). The result was converted to a polygon layer. Polygons with more than 20% agriculture were then ‘burned’ into the original Wildland and Woodland Zones via “Erase” and “Merge”. The zones shown in the “Name” field were subjectively created by Brian Donahue and Brian Hall based on the percent natural land in the original 2010 types and the type of agriculture for the newly added agricultural zones. As with the original 2010 types, this layer should be viewed as conceptual or at best, a very rough estimate of where different landscape types could be located. There were many subjective decisions which had to be made to create this illustrative layer.

GIS Projection All of the GIS layers are in Albers NAD83 projection files.
