Most information on managing private property as wildlife habitat emphasizes one particular type of wildlife. Many references
describe techniques for creating a butterfly garden, or for providing food, shelter and nest sites for birds or for growing
native wildflowers. This article takes a different approach. It focuses on ways that property owners can manage their land
to promote the over-all ecological integrity of the Vineyard.
The first step is to learn the natural history of your part of the Island. To manage land in an ecologically sound manner, one
needs to understand the geology, soil type, human history and natural disturbances such as fire, wind and salt spray that
influence the natural communities.
In general, State Road serves as a convenient dividing line between the moraine to the north and west and the outwash plain to
the south and east. The morainal land between State Road and Vineyard Sound has steep hills, clay soils and numerous boulders.
Although most of this area was once cleared for sheep grazing, it is now regenerating to a mixed hardwood community, with beech,
hickory and holly trees scattered among the dominant oaks. As they woods mature, they become increasingly diverse. This process
occurs naturally and requires no active management by the landowner.
Many of the birds that nest on the moraine require interior woodlands, away from fields, roads and other openings that provide edge
habitat. Skunks, crows, blue jays and other species that prey on eggs and nestlings penetrate the woodlands from these edges. So
do cowbirds, who lay their eggs in other birds' nests, leaving the unwitting parents to raise cowbirds instead of their own young.
By helping to create large, unbroken woodlands, private landowners can support breeding populations of scarlet tanagers, ovenbirds,
veery and similar species, many of which are declining worldwide.
The land from State Road east to Edgartown was created by the sand and gravel washing down from the moraine by the water pouring off
the melting glacier. This flat expanse is known as the Vineyard's great plain. Frequent fires and salt winds combined to keep much
of this area in grassland, pitch pine barrens or savannah. Landowners can mimic some of the effects of fire by annual mowing of
meadows and open areas. Mowing in November helps to spread the seeds of little bluestem, the dominant native prairie grass. Mowing
in March or April leaves the cover standing through the winter, but clears the area for new spring growth.
Some general guidelines will help landowners anywhere on the Island to promote ecological integrity. One is to use native plants
for landscaping whenever possible, preferably from Island seed or stock.
Minimizing the size of lawns and keeping non-native species close to the house while maintaining native species toward the property
boundaries also helps. Invasive non-native species especially Russian olive, bamboo, bittersweet, Japanese honeysuckle, purple
loostrife, Japanese knotweed, multiflora rose and porcelain or chine berry - should be avoided, because they quickly spread and
take over nearby areas.
Protecting wetlands is of paramount importance. Avoid the temptation to "improve" marshes or boggy areas by digging them out to
make ponds. In most cases they are more valuable to wildlife in their natural state. Don't cut shrubs and other vegetation growing
around wetlands. They prevent excess organic matter and other pollutants from reaching ponds and streams, and they provide cover
and a sense of safety for wildlife using the wetland. Seasonally flooded areas known as vernal pools dry up for part of the year and
therefore have no fish. Fairy shrimp and some salamanders and toads will only breed in such fish-free ponds.
Minimize outdoor lighting and turn off outside lights when they are not needed. Even a porch light will attract swarms of moths and
other nocturnal insects, which become easy pickings for skunks at night and birds at daylight. Finally, avoid that ultimate symbol
of suburbia, bug-zappers. They are not only ineffective but kill many beneficial insects. If mosquitoes are a serious problem,
consider putting up bat houses or tree swallow nesting boxes, since both species eat massive amounts of mosquitoes.
