BIODIVERSITY IN PENNSYLVANIA
Surrounded by today's modern conveniences, it is easy to forget that
mankind's survival still depends on the planet's natural biological
diversity. That is, we rely on millions of different kinds of interconnected
animals, plants, and microorganisms — which scientists collectively
call "biodiversity"
— to provide us with the very air we breath and the soil we need to grow food.

Pennsylvania alone is home to more than 25,000 species of known plants
and animals, with perhaps thousands more yet to be identified. Sustainable
use of our natural resources is critical for maintaining the state's
economic health, as well as the quality of life of all Pennsylvanians.

But many threats to our biodiversity are present. Animals, plants, and
their unique habitats are being lost every year in Pennsylvania due
to natural forces, human activities, and lack of coordination. Over
800 plant and animal species are considered to be rare, threatened,
or endangered in the state.

In response to a recommendation by the Pennsylvania 21st Century Environment
Commission, the Pennsylvania Biodiversity Partnership (PBP) was formed
in 2000. The PBP is a public-private partnership to promote the conservation
of native species and their habitats. PBP's goals
were to find out what we know and don't know about Pennsylvania's
natural resources, as well as to make recommendations on how to develop
a comprehensive strategy for biodiversity conservation.

PBP's first step was to analyze the current state of biodiversity
conservation in Pennsylvania. The analysis is contained in Biodiversity
in Pennsylvania: Snapshot 2002, a report that is excerpted and
explained in this LandSavers webcast. Snapshot 2002 examines: organizations
and laws in place to protect Pennsylvania's biodiversity; current
knowledge of the state's biological resources; known threats; how
biodiversity is being managed; and public awareness of biodiversity
issues.

Organizations
State, federal, county, and local governmental organizations all have
a role in managing the lands, waters, and biological resources of
Pennsylvania. Although these multiple government units provide many
tools, they have sometimes lacked coordination in matters of land
use and biodiversity conservation. For instance, responsibility for
monitoring plants, birds, mammals, fish, amphibians, reptiles, mussels,
and aquatic insects is divided among several state agencies. No state
agency has oversight for terrestrial invertebrates, such as earthworms
and snails the largest group of organisms in the state.

Laws and Policies
Although some laws protecting the environment existed prior to the
1960s, there was no concerted effort to protect the use of public
natural resources in the state. With passage of the Environmental
Rights Clause (
Click here to read an article on the ERC ) to the Pennsylvania
Constitution in 1971, the government's attitude changed to one of
trustee for public natural resources. This amendment declared that
the citizens of Pennsylvania have a right to a healthy environment
and guarantees public rights in preservation of natural values in
the environment.
Today, Pennsylvania has numerous laws and policies that relate to
biodiversity conservation. These include laws that govern public and
private actions affecting lands and waters. Other laws and policies
address what biological information is collected, how it is organized,
how it is made available to public and private decision-makers.

Endangered Species
The state maintains an information system for a subset of biodiversity
data: plant and animal species listed as endangered, threatened, or
rare. The computerized system is part of the Department of Conservation
and Natural Resources' Pennsylvania
Natural Heritage Program (PNHP), which was formerly called the
Pennsylvania Natural Diversity Inventory (PNDI). PNHP also contains
data relating to rare and exemplary natural communities and outstanding
geologic features. Pennsylvania's PNHP system is part of a larger,
international system of collecting biodiversity information about
threatened species. PNHP is also pursuing a long-term effort to develop an authoritative checklist of all Pennsylvania biota, including common species.
( Click

networks. )
Species data in the PNHP system is refined and updated based largely on results of ongoing County Natural Areas Inventories. This research is performed by The Nature Conservancy in eastern Pennsylvania and by the Western Pennsylvania Conservancy in western Pennsylvania.
Since 1988, several state regulatory programs have required a PNDI
review as part of an environmental assessment prior to permit issuance.
The PNHP system currently is being upgraded with improved GIS technology
to allow more accurate searches of whether proposed development projects
will impact sensitive species.
Native Species
When it comes to information about common, non-threatened species,
the Snapshot report notes that there are significant gaps
in our understanding of basic questions such as what plants and animals
live in the state, where they live, and their ability to reproduce
and thrive.
( Click
here to see a summary of current knowledge about PA's plants and
animals, Snapshot 2002 report, 347K PDF File.)
The report notes that the state's biodiversity information is scattered
across many agencies and organizations in various formats that are
often incomplete, out-of-date, or inaccessible.
Moreover, although there are several funding sources for biodiversity
research and conservation in Pennsylvania, the amount of money available
for information-gathering does not come close to meeting the projected
needs.

According to the PBP report, threats to Pennsylvania's native species
can be grouped into two major categories: (1) habitat loss and fragmentation;
and (2) pollution. Major sources of these threats include changing
land use patterns, an overabundance of white-tailed deer in many areas
of the state, and invasive plant species. Aquatic organisms, such
as freshwater mussels, have been especially impacted by pollution.
Although there is little doubt that human impacts have been largely
responsible for a decline in biodiversity in the state, there is much
that we don't know regarding how our actions affect species and ecosystems
in Pennsylvania. While progress is being made in correcting some threats,
such as point-source pollution from manufacturing or wastewater treatment
plants, others, such as urban sprawl and invasive plant species, present
increasing problems.

Best Management Practices
Best management practices (BMPs) have become accepted as one
of the most effective approaches for managing natural resources
on both public and private lands. While most BMPs do not specifically
target biodiversity as their primary goal (having, instead,
more limited goals such as prevention of soil erosion), many
BMPs contribute towards this goal. However, the Snapshot report
notes that biodiversity conservation can be achieved only
if the stewards of private lands have the education, tools,
and will to make it happen.
( See these publications outlining BMPs: Forestry
and Forest Management, Wildlife
. )

Land Protection
Land protection activities, including land acquisition, regulations,
incentives, education, and most important, good stewardship
by private landowners, are important components of biodiversity
conservation. Cohesive land protection strategies and coordination
among agencies is essential to achieving the ultimate goal
of biodiversity conservation throughout the Commonwealth.
Habitat Restoration and Species Reintroductions
Restoration and reintroduction projects have been somewhat successful in counteracting the loss of species and habitats in Pennsylvania. The serpentine aster, paddlefish, river otter, and elk are among the species that have begun their resurgence in Pennsylvania as a result of restoration ecology. Restoration and reintroduction projects have taken many forms, ranging from wetland restoration and fire management to replanting native grasslands and relocating animals to their former ranges. Despite the success of some reintroduction efforts, most are costly and many fail.

Surveys reveal that people consistently place a high value
on protecting plants, animals, and their habitats. Although
Pennsylvanians strongly support conservation, their perceived
knowledge about biodiversity, especially the term itself,
is not high. This is not surprising since both the concept
and the term are relatively new, even to scientists.
This disconnect between the public's lack of understanding
of biodiversity and its support for protecting the environment
may be attributed, in part, to a lack of educational materials
on biodiversity. Although concepts related to biodiversity
were reported in many educational programs, the subject was
often limited to individual species or habitats rather than
interrelationships among species. Explanations of why species
have become endangered or threatened, recovery plans, and
critical habitat designations were rarely addressed. The inclusion
of biodiversity in the recently adopted Pennsylvania Academic
Standards for Environment and Ecology may help close this
gap. However, it will not help address the lack of educational
materials on biodiversity available to adult audiences.

The PBP report reveals that despite extensive knowledge about
natural resource conservation in Pennsylvania and many activities
focused on conserving wildlife and habitats, there is much
we don't know about biodiversity in the state. Many gaps need
to be filled. Moreover, despite the importance of biodiversity
and the continuing threats to biological communities, Pennsylvania
lacks a statewide strategy for biodiversity conservation.
Even though PBP members represent a wide range of backgrounds
and opinions, a consensus quickly emerged on the priority
of developing a statewide plan for conserving Pennsylvania's
biodiversity. Benefits of a statewide Biodiversity Conservation
Plan would include:
Facilitate interactions among groups concerned with biodiversity.
Increase cooperation and coordination among government agencies, organizations, business, and individuals involved in biodiversity issues.
Minimize duplication of efforts among organizations.
Establish informed priorities for inventory, monitoring, and conservation at a statewide level.
Increase voluntary stewardship of biodiversity and thus avoid the need for additional regulations.
Increase educational materials regarding the impact and importance of biodiversity to our lives and to the ecological and economic health of Pennsylvania.
The PBP currently is conducting regional public meetings
to gain information for the draft statewide plan.
