NHANRS 2018 Fall Quarterly Meeting–Sept. 20th

NHANRS Fall Quarterly Meeting

Thursday, September 20, 2018

5:30pm to 9:00pm

The Common Man

Concord, NH

Crossing the Blue Line –

Research on NH’s Stream Maps


The National Hydrography Dataset (NHD) is a geographic network containing all water features in the country organized by a hierarchical system of watersheds called the Watershed Boundary Dataset (WBD). Everything in the NHD is connected, enabling users to trace the network to discover information along the streams and waterbodies (dams, stream gages, water quality stations, etc.). The current High Resolution NHD contains all water features on 24,000-scale USGS topographic maps. Although a remarkable achievement, many workers today require a much finer scale. With Lidar elevation data and GIS tools, we are now able to extract a stream network that represents reality to within a few meters. This method indiscriminately generates all streams on the basis of channel morphology, but cannot identify whether any given stream reach is perennial, intermittent, or ephemeral. To better evaluate these classifications, the NHGS has deployed stream permanence sensors that monitor the height of water in the channel. These methods, combined with a new NHD Markup Tool that allows the public to propose edits to the stream network, will allow the NHGS to make the NHD in New Hampshire a better product for all.users.

Presenter Bio

Joshua Keeley is a Hydrogeologist with the NHGS and serves as the New Hampshire Principle Steward of the National Hydrography Dataset (NHD). Josh specializes in glacial geology and is currently involved in surficial geologic mapping, maintaining the NHD, maintaining NHGS’s Groundwater Monitoring Network, and hydrologic modeling of NH rivers. He received his B.A. in Geology and Geological Oceanography from University of Rhode Island in 2008 and his M.S. in Geology from Idaho State University in 2011.

Dirt to Trees to Wildlife Workshop–8/14/18

Dirt to Trees to Wildlife

Tuesday, August 14, 2018
12:30pm – 3:30pm

What you will learn: Identifying opportunities to enhance wildlife habitats requires knowledge, skills and experience related to interactions between soils, vegetation and the wildlife that use each type of vegetation. A new online tool helps professional managers simplify the process of compiling these complex interactions. The tool, called Dirt to Trees to Wildlife (DTW), simply requires a user to identify a piece of land by drawing it on a map. Behind the scenes, DTW identifies the soils on that land, the vegetation naturally supported by that soil, and wildlife breeding habitats supported by each vegetation type. This information is compiled in a handy report to inform management decisions.

DTW is based on decades-long work reflecting collaboration by soil scientists, foresters, researchers and wildlife biologists. It is largely funded by the U.S. Forest Service and the Randolph Community Forest in Randolph, NH.

At this workshop you will be introduced to the DTW online tool, set up a free ArcGIS online public account, and develop a report for a tract you identify. Bring your laptop with Windows 7 or 10. A limited number of computers will be available. Request one with your registration.

The NH GIS Technical Advisory Committee Task Force is developing a long-term plan for regular acquisition of statewide aerial imagery that will meet the needs of GIS data users throughout New Hampshire. If you make use of GIS data and aerial photography in New Hampshire, you are invited to participate in an important conversation about the future of statewide imagery collection.

Input is being sought from GIS data users concerning their current and expected future use of statewide aerial imagery and desired technical specifications for the applications they support.  You can represent the needs of your organization, town, or agency by completing an online aerial imagery needs assessment survey, and/or attending an input session.

NH Invasives Academy: Now Accepting Applications

UNH Cooperative Extension will host the inaugural NH Invasives Academy, a 2-day workshop focused on invasive plants on September 27-28 at the Seacoast Science Center in Rye.

At this special two-day workshop focused on invasive plants, up to 40 attendees will have the opportunity to attend presentations, participate in hands-on activities, learn from colleagues, experts, and each other, and attend field trips covering ecological considerations and management strategies for invasive plants in New Hampshire. Instruction for the Academy will be provided by a diverse group of agency, academic, non-profit, and private industry partners. Attendees will learn tools and techniques to improve their management plans and activities. The Academy is designed for those with a strong interest and some experience in natural resources stewardship, including foresters, land trust staff, natural resource professionals, private landowners, and active community volunteers. In exchange for the 2-day training, participants agree to return to their New Hampshire communities and contribute 20 hours of time sharing information learned with landowners, colleagues, clients or other members of their community. A $65 registration fee partially covers meals, transportation, and materials. Applications will be accepted on a rolling basis through September 15th, with application review beginning on August 1st.

Wetland Buffers

The NHANRS Legislative Committee and Board of Directors formed the NHANRS Wetland Buffer Scientific Workgroup in 2015.

The NHANRS Scientific Wetland Buffer Report was finalized on June 13, 2017. Read the report, workgroup meetings minutes and agendas, literature and other links on the Wetland Buffer Scientific Workgroup Homepage.
