7.0 BIOLOGICAL RESOURCES
The State of New Jersey's Landscape Project Version 3.3 mapping uses the State's land use/land
cover GIS data and biotics species occurrence data to model species habitat locations in the state.
The landscape regions are broken down into six (6) regions: Atlantic Coastal, Delaware Bay,
Piedmont Plains, Pinelands, Skyland and Marine. Egg Harbor Township is primarily located
within the Pinelands Landscape Region. The southern portion of the Township, along the Great
Egg Harbor River, is located within the Delaware Bay Landscape Region, and the eastern portion
of the Township is located within the Atlantic Coastal Landscape Region (see Figure J). This
mapping is a guide for strategic wildlife habitat conservation design to identify not only
threatened and endangered species in New Jersey but to identify and protect the habitats in which
they live. It is a full ecosystem-level approach for long term protection. The habitats located in
Egg Harbor Township fall under Suitable or Critical Habitats in every land use category. Critical
habitats are areas identified with a higher number of threatened and endangered species, and
therefore have a more urgent need for conservation of the habitat.
Perhaps more than any other single natural feature, the unique patterns of vegetation in Egg
Harbor Township define the region's distinctive, essential character. While vegetation refers
generally to an area's plant cover, the distribution of specific vegetation types in a localized area
is governed by a combination of factors which make up the local habitat. Climate, soil, animals,
man, fire, time, and other plants are just some of the factors which interact to produce the
environment, or habitat in which a plant grows. Climate is a measure of temperature, rainfall,
snowfall, wind and other types of weather factors. Animals may affect plants by grazing or
transporting their seeds. Soils affect plants by their ability to support roots and hold water and
nutrients. Fire may eliminate species of plants unable to reproduce by resprouting, and may
cause an increase in those that can resprout.
Vegetation, whether a forest or an old field, changes like an individual organism in appearance
and structure over time. Forests age very slowly, requiring hundreds, even thousands of years to
reach a stable state of species size and composition, known as a climax state. For this reason,
changes due to aging of a forest are frequently hard for humans to recognize. As time goes on,
some forest species become less suited to the slowly changing conditions for survival while
others become better suited. The result is a decrease in the numbers of some species while the
proportions of other competing species increase. Such changes in the composition of species
through time is known as succession.
The single factor which is most important for differentiation of plant habitats within Egg Harbor
Township is the amount of moisture within the soil substrate, that medium in which the plants
are rooted. Different plant species differ in their requirements for water as well as their ability to
tolerate extremes of excessive water or drought. Certain plants can live only in standing water
while others are adapted to much drier conditions, and still others are best suited to various
gradations of saturation between the two extremes. Since rainfall distribution is virtually the
same throughout the Township, the amount of water available to plants through the soil is
controlled primarily by the relief of the land surface and the depth to groundwater. Groundwater
