This map was created by taking the following dataset and overlaying them using the same symbolization for each dataset. Asco-occurrences happen, the symbology will show darker and darker

on the map. The darker green values show the places where thehighest amount of co-occurrence. One should be careful not to tryto ascertain the data sauce from this base map, since each layer isweighted, there could be several concurrences that do not equal

a non co-occurrence of a highly weighted dataset. Unfragmented lands used on this map were create at part of theNew Hampshire Wildlife Action Plan. This plan was updated in2010. This data was created by removing fragmenting features

from the landscape.Water Buffer the water features on this maps are the line and

polygon data from the New Hampshire Hydrography Dataset.These features were then buffered by 100'. This data did include

'wetlands' as defined by the parameters of the Hydrographydataset.

Prime wetlands on this map were supplied by the town GIS. Thisdata was supplied as is, and is presented as sent from the town

GIS.Important agricultural features on this map are composed of twodatasets. Prime farmland dataset is supplied by the RockinghamSoil survey plan, this data shows lands that have an adequate and

dependable water supply from precipitation or irrigation, a favorabletemperature and growing season, acceptable acidity or alkalinity,

acceptable salt content, and few or no rocks. Farmland ofstatewide importance is also from the Rockingham County Soil

Survey, this shows prime farmland and that economically producehigh yields of crops when treated and managed according to

acceptable farming methods. Some may produce as high a yield asprime farmlands if conditions are favorable.

Forested landuse is from the 2005 Landuse data as created by theRPC in 2006 as part of the CTAP Landuse process.

Conservation Easements are supplied by the Town of Salem GIS. This is an older set of this data, to be updated. This data was

current to 2007. This is by no mean comprehensive and should berefined throughout this process.

This map shows two different layers that approximate properties thatare protected in some manner. In some cases protection will be noted and in some cases the type of protection is not known from

the datset. The 'Conserved Properties' layer is from the Salem GIS. This seems

to show parcels which have some manner of protection. Where aparcel is shown in this layer it appear that the spatial extent of theprotection is displayed. In other words, parcels that are partially

preserved the full extent of protection and non-protection is shownproperly in this layer. However, this layer is missing several

properties that the Open Space Committee noted had some levelof protection and is also lacking in the communication of the type

of protection of the pacels shown.The 'Protected Properties' layer shown on this map was digitized

from spreadsheet supplied to the RPC from members of the OpenSpace Committee and Conservation Commission. These

spreadsheets called out full parcels that had some measure ofprotection and the type protection implemented on each parcel. This dataset doesn't take into account the amount of each parcel

that is actually protected, in all cases the entire parcel is called outwithin this dataset.

These two datasets together do a good job of representingprotected land within town, however, each has it's own faults. TheRPC would be remiss to show one dataset and not the other. Withthese warnings, these datasets should be used together with thecaveat that neither is 100% accurate and should only be used for

planning purposes.
