Species
Conservation
Rare species in Massachusetts are threatened
primarily by habitat loss or degradation. Management of rare species
may mean giving special help to species that have been lost from
the state or that are dangerously close to being lost. Special efforts
made for rare species in Massachusetts include the building of nesting
platforms for Osprey and nesting rafts for Common Loons, collecting
Plymouth Redbelly turtle eggs to release "head-started"
hatchlings, and reintroduction programs for 4 species. Bald Eagles
and Peregrine Falcons are nesting in Massachusetts again, due to
ambitious restoration projects sponsored by NHESP. Young eaglets
were raised and released at the Quabbin Reservoir in central Massachusetts.
There are now 12 nesting pairs of Bald Eagles that call Massachusetts
home; nests in Massachusetts have produced 141 Bald Eagles since
this reintroduction project started. Two pairs of Peregrine Falcons
have been nesting in Massachusetts for 15 years. The peregrines'
choice of nesting sites, skyscrapers in downtown Boston and Springfield
and a bridge in Fall River, may seem unusual but these sites offer
some of the same advantages as the cliffs that peregrines had traditionally
used. Additional pairs may colonize other urban buildings and bridges
or natural cliff sites.
Here are a few examples of how Natural Heritage
has used species recovery projects to restore the state's native
biodiversity.

Piping
Plover (Charadrius melodus)
Primary
Cause of Decline:
Off-road vehicles/Recreation, Predation
Restoration
Efforts: Minimize
human-caused disturbance and mortality, Reduce nest predation, Protect
habitat
Pre-Restoration
Status: Approx.
131 pairs, 1985
Current
Status and Trend (1999):
Over 500 breeding pairs, increasing - see
above
Piping Plovers have made a dramatic comeback
in Massachusetts as a result of 14 years of cooperative efforts
by a dedicated and diverse group of conservationists and land managers.
The Piping Plover is a small shorebird that nests along sandy coastal
beaches from North Carolina to Newfoundland. Along the Atlantic
coast, it is listed as "Threatened" by the U.S. Fish &
Wildlife Service and currently numbers less than 1,400 breeding
pairs. The Massachusetts population, listed as "Threatened"
under the Massachusetts Endangered Species Act, has increased from
139 to over 500 breeding pairs between 1986 and 1999-- an increase
of 260%!-- and now represents one-third of the entire Atlantic coast
population.
The
Natural Heritage & Endangered Species Program has coordinated
efforts to protect the Piping Plover population in Massachusetts.
These efforts include protecting birds from human disturbance, reducing
predation of eggs by placing wire fences around nests, restricting
off-road vehicles to protect nests and chicks, and using Massachusetts'
Wetlands Protection Act to protect habitat from degradation caused
by dune building and other detrimental activities. A beneficial
side effect of the piping plover recovery has been the increased
protection for large areas of the coastal beach and dune ecosystem,
along a coastline that's valued for its beauty and recreational
capacity. Cooperation from the public and between private organizations
and state, federal and municipal agencies has made this success
possible.

Scientists
don't fully understand the factors that contribute to the growth
and reproductive success of some rare plants. For example, a plant
may be sensitive to too much shade or dependent on the intense heat
of a fire to activate dormant seeds. NHESP has been participating in
experiments aimed at determining the needs of Sandplain Gerardia,
a federally endangered wildflower. Experimental plots on Cape
Cod and Nantucket were treated with a variety of techniques,
including controlled burning, fertilization, and scarification (raked
with hand tools or turned by tractor disc). The success of seeds
planted in the various plots was measured by the percentage of seeds
that sprouted and by the size of the resulting plants. Surprisingly,
more Sandplain Gerardia were found at the experimental plots
in 1995 than at the parent colony from which the seeds were
taken. We are getting closer to identifying management techniques
that can be used to successfully restore this annual species
to suitable habitat within its historic range.
