Abstract:
This raster dataset has been created using "Pennsylvania Land Cover dated 1992" developed by the EROS Data Center for EPA Federal Region III (see metadata entitled "Land Cover 1992 EPA Federal Region III.pdf") and Landscape Blocks as originated by The Nature Conservancy. Using an inside buffer of 18 meters on the Landscape Blocks a new shapefile was created in order to create a 30 meter area between the blocks to represent roads and then the road buffered landscape blocks were combined with the Forest cover (Coniferous Forest, Mixed Forest, Deciduous Forest, and Woody Wetland) raster to assign a value of "0" to areas in the natural vegetation land cover that overlap with the road buffers. Using an inside buffer of 30 meters on the Forest cover (Coniferous Forest, Mixed Forest, Deciduous Forest, and Woody Wetland) from the 1992 land Cover, the interior forest raster was created. Acreage of the contiguous interior forest was calculated and the data was reclassified based on conservation value as follows:

Acreage	Conservation Value
0-25 			0
25-50 			1
50 - 100 		2
100 - 150 		3
150 - 225 		4
225 - 300 		5
300 - 400 		6
400 - 500 		7
500 - 750 		8
750 - 1000 		9
>1000			10  
No data		    	0

Conservation values were determined by experts gathered by Natural Lands Trust through SmartConservation®. This data set is one of several that have been combined to create an overall terrestrial resources conservation value raster for the expanded piedmont ecoregion. Therefore the values were determined as a relative rank, comparable in value only to the other input terrestrial resources data. Conservation value ranges from 1 - 10 with 10 being the highest value.
Purpose:
Assign conservation value to Interior Forest Habitat Potential within the Expanded Piedmont Ecoregion of Pennsylvania.

Save as: " 'study area'_Forest_LC"
in \individual_grid\'study area'\Forest_LandCover\

** Use the appropriate gridcode that represents forest land cover, the gridcode will probably be different in updated land cover

Convert to feature
Input: " 'study area'_Forest_LC"
Save as: " 'studyarea'_Forest_Landcover"
In: \'study area'\shapefiles\

Buffer to create exterior forest
Use Buffer wizard tool in ArcMap
Input: " 'studyarea'_Forest_Landcover"
At a distance of 300 feet 
Dissolve barriers - yes
Only inside the polygon
Save as: " 'study area'_Exterior_Forest"
In: \'studyarea'\shapefiles\

Convert exterior forest to raster
Input: " 'study area'_Exterior_Forest"
Save as: " 'study area'_ExtFor"
In: \'study area'\individual_grid\exterior_forest\



Reclassify to set NoData area to "1"
Use mask : 'Study area'
Input: " 'study area'_ExtForest"
Old Value		New Value
0 (Buffer)		0
NoData	 (Other Area)	1
Save as: " 'study area'_ExtForest"
In \'study area'\individual_grid\exterior_forest\reclass\

Multiply Forest Land Cover x Exterior Forest
makes a grid where the no data/buffer of exterior forest is removed from Forest Land Cover
Raster calc: (['study area'_ExtForest] x ['study area'_Forest_LC])
save as: " 'study area'_IntForest"
in \'study area'\individual_grid \Interior Forest\

Perform Region Group 
Region group assigns a unique number to each group of adjacent cells with the same value 
Raster calc: Region Group ({'study area'_IntForest])
save as: " 'study area'_IntFor_RG"
in \'study area'\individual_grid \Interior_Forest_regiongroup\

Perform Zonal Area 
Zonal Area assigns area in square meters (using UTM meters) to unique numbers
Raster calc: Zonal Area (['study area'_IntFor_RG])
save as: " 'study area'_IntFor_ZA"
in \'study area'\individual_grid \Interior_Forest_zonalarea\

Convert area to Acres
Raster calc: (['study area'_IntFor_ZA] / 4050)
Save as: " 'study area'_IntFor_Acr"
in \study area\individual_grid\ Interior_Forest_acreage\

Reclassify to assign conservation value (peer/biological)
Use 'study area' as mask
