1996 Coastal Habitat Restoration Report

Project Overview
This report and an associated database of restoration projects are
intended to increase the effectiveness of coastal habitat and species
restoration in the Gulf of Maine by expanding coordination and facilitating
information exchange. The project was initiated in October 1996 in accordance
with one of the priority goals of the Gulf of Maine Council on the Marine
Environment (GOMC): to "Identify, protect, and restore the Gulf’s terrestrial,
coastal and marine habitats." GOMC is a collaborative organization formed
by the states and provinces of the Gulf (Massachusetts, New Hampshire,
Maine, New Brunswick, and Nova Scotia) that strives to maintain and
enhance environmental quality in the Gulf of Maine to allow for sustainable
resource use by existing and future generations.
Various types of information have been collected and are included in
this report, including data on contacts (i.e., consultants, researchers,
managers), bibliographic references, information on existing evaluative
methodologies, and information on the restoration of tidal marshes,
freshwater impoundment construction, tidal flats, seagrass, dunes, seabird
populations, and anadromous fish. Information specific to past and current
tidal marsh, freshwater impoundment, tidal flat, and seagrass restoration
projects was entered into a database on coastal wetlands (Table 1).
Although information on dunes and restoration of seabirds and anadromous
fish is presented in this report, it was not included in the database,
due to the types of data collected and because central sources for data
already exist. The database was constructed using Microsoft AccessTM
and currently contains descriptive information such as project location,
site and work descriptions, information on monitoring, and contact information.
During data collection, several sources of information on potential
tidal marsh restoration projects were uncovered. These sources have
identified approximately 350 sites in Massachusetts, New Hampshire,
and Maine that have restoration potential. These sites were combined
and added to the database to assist in future project implementation
and to expose restoration opportunities (Table 2). Similar sources of
information on potential projects were not found for Canada. The database,
as well as this report, will be made available on the Gulf of Maine
Council’s Website at www.gulfofmaine.org.

Number and acreage represent those projects for which information
was collected and entered into the database as of March 1998. Projects
indicated are underway or complete. Acreage does not imply that the number
of acres shown were "successfully" restored.

A total of 355 tidal marsh sites have been identified
in Massachusetts, New Hampshire, and Maine as of April 1998. 3,746 acres
were tallied for 260 of these sites. Since acreage is based on fewer than
the total sites identified, acreage is underestimated. Sources of data
and information are listed in Section 3.
Key Findings
Key findings are provided for each of the major categories for which
information was collected. More detailed information is provided in
the Sections to follow and in the Coastal Wetland Restoration Database.
