Declining
Forest Stands in the
Inland Bays
Anyone
has been to any of the Inland Bays beaches a few times in
the past few years
knows that the whole area is becoming more intensely developed.
Rob Line, the Natural
Heritage Program Manager for DNREC, is
concerned
about the
cumulative impacts of development and began tracking land use changes
across the state. The Inland Bays watershed is of particular interest
because of its rapid growth and water quality problems.
Even
Geographic Information System (GIS) maps, which show land use
derived from
aerial photographs, can’t keep up with the rate of growth.
Currently, we use 1997 aerial photographs for our baseline, the
last time land use maps were updated. New aerial photography
is in development for the years 1937 and 2002, and will be
available this Summer. With the resulting maps, planners will
be able to estimate the rate of forest decline and though fragmented,
which
areas retain sizeable forest acreage.
Land
use has changed over time. As Rob explains, “Many of
the original farmers of the area who had the poorest land left
the area in the early 1800s because the soils lost there fertility
and became 'played out'. The abandoned farms gave way
to loblolly pine forests that contributed to record timber harvests
around 1900. This coincided with the estimated lowest total acreage
of forests in the area in the 1880s or 1890s.”
Accompanying
this peak was the zenith of the shipbuilding and timber harvesting
age in Delaware. The large stands of loblolly pine eventually
gave
way
to orchards and strawberry fields. After the birth of modern
poultry production, cereal crop production took over after the
Great Depression,
and until recently, was the largest land use in the area. Suburban
development is quickly changing the picture. In fact, Rob identifies
development as the largest threat to the Inland Bays’ environmental
balance; forests, wetlands and tidal reaches.
State
and private conservation efforts have focused around several
protective organizations. Delaware
Wild Lands, Inc. has bought
land around Angola Neck, a narrow strip
of land extending into the Bays, adjacent to the Great
Cypress Swamp State Park. DWL is a private non-profit organization
committed to preserving important natural resource lands throughout
the state.
The Delaware
Nature Society is perhaps one of the state’s
best known environmental education organizations. DNS focuses
much of its resources towards legislative efforts as well as
landowner
education. It sponsors activities such as Backyard
Wildlife Habitat,
a certification program of a yard or garden as suitable habitat,
and Stream
Watch, where volunteers monitor and evaluate the water
quality of neighborhood streams, reporting their data to
the state-wide effort. The Nature Conservancy, although a world-wide
conservation organization, has protected several hundred acres
in the Inland Bays watershed. They concentrate on land acquisition
in Areas of Concern, as identified by Ecological Regional Planning.
These are target areas, such as streams and seashores and headwater
forests, which perform vital environmental functions.
Delaware
State Parks, and Fish and Wildlife Management Areas work to
protect forests in the Inland Bays Watershed, largely near
the
bays. The Delaware
Forest Service a division of
the Delaware Department
of Agriculture protects
some working forests, especially in the headwaters areas of
the watershed.
Since
land prices have risen in recent years, conservation can be difficult.
State and private organizations increasingly rely
on donations
by land owners. As a quasi-government organization, the Sussex
County Land Trust has set aside close to $1 million dollars
to buy land and open space, preserving it for the public
good.
Rob
also points out the least protected habitats are those of the
upland forest, "The tidal reaches of the Bays have federal
and state protection and freshwater wetlands have federal protection,
but upland forests have no formal protection.”
Forests
are an important part of ecosystems, providing free environmental
services for Delaware’s citizens, vital habitat for birds
and animals, flood plains along streams and
recharge areas for aquifers. Remarkably, after 300 years of consumption
and utilization of forest habitats for human uses, many large
forest tracts remain in the watershed. Their future depends on
all of
us. With many organizations working towards the same goal of
preservation, the future of the Inland Bays forests has hope … but
we all need to work together to help wisely manage them into
the future.
