For those of you who are NH Wetlands Mapper users, we are letting you know that the Mapper will be down for 4-6 weeks. Unfortunately the server crashed and it will take a while to rebuild and transfer data layers to an alternative server. In the meantime, you can use GRANITView mapper to view wetlands data layers, although it does not have the functionality of the NH Wetlands Mapper (no drawing tools, buffer width calculations, etc).  We will notify you as soon as the Mapper is functioning again. Our apologies for any inconvenience this causes.

The Method for Inventorying and Evaluating Freshwater Wetlands in New Hampshire (NH Method) provides
communities, conservation groups and professionals a practical method for evaluating wetland functions.
Originally published in 1991, the NH Method was first revised  in 2011 and updated in 2012 and 2013.

The NH Method Manual is only available via this website as downloadable Sections and Appendices.

The NH Wetlands Mapper is an online mapping tool designed as a companion to the NH Method.
