Conservation & Public Lands GRANIT Data Layer update

2021 Conservation & Public Lands GIS Data Layer update
Submissions Deadline:  June 11, 2021

We invite you to participate in the 2021 update of NH GRANIT’s Conservation and Public Lands GIS data layer. As you know, this data layer is critically important for informing our individual and collective land protection efforts, from local to regional, and statewide to multi-state conservation initiatives. However, NH GRANIT relies on us all to submit new and updated information to keep the data layer current and to maximize its effectiveness.

I fully appreciate the challenge of regularly submitting conservation updates to NH GRANIT, which is why I am writing to offer some help. Similar to update efforts in the past, The Nature Conservancy (TNC) is partnering with NH GRANIT to solicit new and updated conservation land information, process submissions, and submit them to NH GRANIT for incorporation into their database.  We are especially pleased to be working with the UNH Sustainability Institute this year on the project. Madeline Peery will undertake the update effort this summer as the Conservation Lands GIS Fellow through UNH’s Sustainability Fellowship Program.

There are three main ways that we can help support your organization or town through this update effort:

  1. Provide you with the self-service resources to submit your updates

You will find all of the data submission resources at NH GRANIT’s website here, including the following documents (see links at the bottom of the web page):

  1. Conservation and Public Lands Data Standard document (this document explains the fields and codes used when submitting records) 
  2. Tract Data Sheet for submitting conservation land records
  3. Tract Data Sheet Instructions ***I recommend reviewing these instructions first***Also, please submit your updates to me at for this update effort instead of directly to NH GRANIT. 
  4. Digital Submission Instructions for land trusts with GIS capabilities. Again, please submit your updates to me at for this update effort instead of directly to NH GRANIT. You can download and use GIS software to view the most recent Conservation and Public Lands data from the NH GRANIT website (last updated 6/16/2020), which you can also use as a data submission template, or download the submission template shapefiles directly from here.
  1. Answer your questions throughout the process and provide additional information

Having trouble deciphering the instructions or attribute codes from the resources listed above?  Or you just need a little support getting started?  We are here to help!  Please call or email me (my contact information is below).  Madeline will be available to provide technical assistance and support from mid-June to mid-August. 

If you don’t use GIS, we can provide summary tables for the tracts of land that your organization is associated with in NH GRANIT. And you can use the GRANITView web mapping tool to review conserved property boundaries and their attributes—check out the Getting Started with GRANITView document if you are new to this tool. Need help?  Let me know.

  1. Provide web-based support to a limited number of organizations and towns

On a limited basis, TNC will work hand-in-hand with land trusts to help assemble conservation land updates. We can schedule a web meeting and share screens to pull your new and updated conservation land information directly into NH GRANIT’s data format. We like to reserve these opportunities for groups with limited GIS capacity.  If you are interested please email me and we’ll work to schedule a time between mid-June and mid-August; these meetings are available on a first come, first serve basis.   

Please submit your conservation updates to me at your earliest convenience, but no later than June 11 to ensure we have time to process updates and submit them to NH GRANIT by the end of the summer. Please let me know if you intend to submit updates but can’t do so by June 11 so that we can plan accordingly.

Here are two final requests…. First, three really important attributes in the GIS data layer could use your organization’s review to make sure tracts of land are coded properly. These include the Level of Protection (LEVEL_), Management Status (MSTATUS), and GAP Status (GAP_STATUS). This document explains each of these attributes and the codes associated with them on pages 14 and 17. We have a lot of records attributed as code 9 (unknown) and it would be great to update as many of the unknowns as possible. Second, we’d like to explore differentiating legally protected agricultural lands from how they are currently tracked in the database (MSTATUS 4 and therefore GAP_STATUS 4). If your organization can send us an attributed shapefile of legally protected agricultural lands we’d be most appreciative. This will help us develop a better understanding of these lands in our conservation portfolio across the state.

Thank you very much for your assistance with this important project, and please do not hesitate to contact me at if you have any questions.
