Habitats and
Development
Ecosystem
Processes and Human Regulation
In
relation to the development of RTP, buildings appear to be encapsulating
the landscape. As a result,
parking lots and manicured lawns are eliminating the natural habitats for
many native species. At the
current rate of development, the corporate growth will eventually reach a
level which fully destroys the potential for native habitats in the RTP
area. The outcome of a
destruction (human regulation of wildlife) of this magnitude is difficult
to predict, because of the extreme time delays of ecosystem
reactions. It is probable
that highly valuable species reside in the natural areas of RTP and are
struggling against development. Perhaps one of these species will be found
to be life saving in the future, but instead of providing a landscape for
the many pharmaceutical companies of RTP to research the species, its
habitat was replaced by well-manicured lawns or cemented parking lots,
forcing it into extinction.
The
ecosystems within RTP are highly fragmented by the many buildings, which
leads them to be fragile and vulnerable to the commonly occurring negative
human interactions. As buildings continue to rise, the remaining habitat
areas of RTP are becoming more isolated and “island-like” with no
connection to other habitats.
Species are able to cross a very limited distance of non-habitat in
attempting to move between habitats.
This mobility restriction, as well as, the constant habitat
shrinking, will lead to a significant decrease in species diversity. A low species richness will lead
to an abundance of dominant common species and an elimination of rare
species. Considering the
value of most species and the effects of extinction yet to be determined,
measures must be taken to avoid destroying habitat.
Growth
Limitations
All
species have a tolerance area, referred to as a niche, in which
they are able to deal with and sometimes require factors influencing their
growth, without extreme harm to the species population. Human interaction within the
natural areas of RTP is a prime example of regulating a niche. Too much human interaction in
habitat areas is highly disturbing to the population and falls outside of
the niche boundaries. In this
situation, too little human interaction will also harm the species and
fall at the other extreme of the niche boundaries. While nature is often thought to
be best left untouched, this landscape requires some outside
influence. If RTP is allowed
to continue to expand with no work to protect habitat areas, the niche of
many species will be destroyed.
Therefore, corporations need to address the situation and actively
work to restore previously degraded habitats on company lands, as well as,
enhance current habitat areas to provide for greater populations.
Complexity within Ecosystems is Critical to
Viability
Simplification of the landscape greatly reduces species
diversity, which in turn reduces genetic diversity and functional
diversity. Corporate
simplification of landscapes is common within RTP. Well-manicured lawns and cemented
parking lots are more aesthetically pleasing to most business people than
seemingly overgrown natural grasses.
However, the installation of these non-complex landscapes, not only
removes the previous natural habitat areas, but also caters to the
dominant common species rather than including the interests of rare
species. Species richness is
important for the preservation of genetic and functional complexity within
species to allow for adaptation, immunity, and disturbance
resistance.
Landscape
complexity within RTP offers numerous advantages, not only to wildlife,
but to the entire corporate community as well. Allowing for natural growth to
replace turf grass will greatly reduce the expenses of mowing and
fertilizing a lawn, which provides little habitat. Elimination of pesticides and
fertilizers on the lawns surrounding RTP buildings, will greatly reduce
pollution to local waterways.
Furthermore, the natural growth will greatly reduce runoff which
causes flooding, an issue common to the Triangle area.
Excess corporate lands throughout RTP hold great potential for
serving as buffer strips between the “island” habitats which fall between
buildings. This will
significantly increase species movement and diversity. Increasing on-site wildlife
enhancement programs at all companies in RTP will prevent the elimination
of species through destruction of their niche, and perhaps increase
species diversity. Simple,
inexpensive, sometimes even money saving, enhancement projects will have
substantial positive effects on local
species.
