Dune Restoration

Dune Revegetation

Sand dune vegetation plays an important role in trapping sand to build dunes. In addition, the roots of dune plants assist in anchoring the dune in place. Seeds harvested from native plants within the Newbury dunes were propogated at UNH's Jackson Estuarine Laboratory, and by horticulture students at Dover High School, to provide plants for revegetation efforts. In addition, plants were purchased from a local nursery and donated from a local property owner to provide the volume needed to plant the restoration area. Native species used in the restoration project include American beach grass, seaside goldenrod, sea rocket and beach pea.

The team worked with over 125 volunteers including local citizens, school children, NH Sea Grant/UNH Cooperative Extension's Coastal Research Volunteer program, as well as students from UNH, to revegetate the Newbury dunes. Over 30,000 plugs of beach grass were established, approximately 6,000 goldenrod, and  1000 sea rocket and beach pea were planted between Fall 2014 and Spring 2015.

Sand Fencing

Sand fencing was erected to assist in capturing sand to build up the dunes, as well as to protect newly planted vegetation. Volunteers assisted in installing over 1000 linear feet of sand fencing in Newbury.

Dune profiles

Using laser level survey equipment, the project team with help from volunteers, takes measurements of the profile of the dune (i.e., in a line from the land to the ocean). By collecting this information over time, we can understand the change in shape of the dunes, and gains/losses in sand volume, data collection points were established throughout the dune system.

Get Involved

Volunteer opportunities are available for people of all ages. Calendar coming soon.
