System Goals
An ecological reserve system is a collection of lands managed and monitored to protect
biodiversity in all its forms.
The goals of the system are to:
- Perpetuate all elements of native biodiversity at all levels
- genetic, species, community, ecosystem - including all stages of
succession.
- Maintain ecological and evolutionary processes at their
natural frequency and spatial scale on a portion of the landscape sufficient to
perpetuate biodiversity.
- Provide comprehensive representation of physical elements.
- Serve to increase our understanding of the benefits of healthy, functioning ecosystems
An individual ecological reserve is an area of land or water
that contributes to one or more of the system goals. Ecological reserves within
the system vary in size, location, ownership and protection strategy. Human
uses of ecological reserves are encouraged, as long as those uses are
consistent with the goals of the ecological reserve system and the protection
of the features of biodiversity supported by the individual reserve.

Ecoregions
To ensure that the ecological reserve system captures and conserves biological resources that reflect broad patterns of biodiversity on the landscape, the Project is using ecological regions to establish protection goals. Building on U.S. Forest Service analyses of climate, topography and soils, scientists divided the state into nine ecological regions:
- Connecticut Lakes
- Gulf of Maine Coastal Lowland
- Gulf of Maine Coastal Plain
- Mahoosuc-Rangely Lakes
- New Hampshire Upland
- Northern Connecticut River Valley
- Sebago-Ossipee Hills and Plain
- Vermont Piedmont
- White Mountains
The Project established a goal of conserving at least three
populations or occurrences of each element in each of New Hampshire's nine
ecological regions in which the element occurs.

The Need
New Hampshire is home to more than 15,000 species of plants and animals,
100 types of natural communities, and ecosystems as diverse as the Great
Bay estuary, the spruce-fir forests of the North Country, the summits of
the White Mountains, and the floodplains of the Merrimack and Connecticut
Rivers. This rich biological diversity, which includes not only plants and
animals but also the habitats and ecological processes that sustain them,
is a living legacy that helps keep our air clean, our water pure, our economy
strong, and our quality of life high (For a primer on the biodiversity of
New Hampshire, refer to New Hampshire's Living Legacy, published in 1996
by the Fish and Game Department's Nongame and Endangered Wildlife Program).
The biodiversity of New Hampshire, however, is vulnerable to ongoing development
and degradation. For example:
- New Hampshire has already lost important aspects of its biodiversity
at the species, natural community, and ecosystem level. 11 species
of animals and 13 species of plants have been extirpated from the
state. Some types of unusual natural communities have declined,
notably pine barrens. Of four pine barrens that were found in the
state, only one remains. Despite extensive reforestation since the
mid-1800s, there is a lack of undisturbed habitats including grasslands,
waterbodies, and riparian corridors, and mature forest types such
as northern hardwoods, oak-pine, and spruce-fir.
- New Hampshire is losing more than 13,000 acres of open space to
development each year.Based on estimates from the state's Forest
Resources Plan, approximately 189,600 acres of forests (3% of the
state's total area) were developed between 1982 and 1997.
- Of the top 10 environmental risks ranked by the New Hampshire Comparative
Risk Project, 6 risks are related to loss, degradation, or alteration
of land or water habitats. The predominance of habitat-related
threats is especially alarming because the Comparative Risk Project
examined a broad spectrum of environmental risks, including those
with direct impacts on human health, and did not start with a focus
on biodiversity or land and water conservation.
- There are 22 plant species, 30 animal species, and 25 natural community
types in New Hampshire that are considered globally rare or imperiled.
- We know of exemplary occurrences for fewer than 50% of the natural
communities in the state, including common and widespread natural
communities.
- There are few, if any, undisturbed aquatic ecosystems in the state. Aquatic ecosystems are under particular pressure due to ongoing hydrologic alteration and shoreline development.
Though conservation lands compose approximately 20% of the land area in New Hampshire, the current system of conservation lands in New Hampshire does not appear to provide comprehensive, long term protection of biodiversity at the species, natural community, or landscape levels. As a way to evaluate the effectiveness of the current system of conservation lands, we used existing databases housed at the Natural Heritage Inventory and the Fish and Game Department to determine what portion of known occurrences of rare species and natural communities occur on conservation lands. We utilized the conservation lands layer developed by the Society for the Protection of New Hampshire Forests.
There are 2 or fewer known occurrences on conservation lands for:
- close to 60% percent of classified rare natural communities.
- nearly three-quarters of known rare plants.
- over three-quarters of known rare vertebrate species.
- over 90% of known rare invertebrate species.
Many species, natural communities, and landscape types are known to be well represented on current conservation lands or are protected through private lands management. In addition, there are significant portions of the state that are extensively forested and are experiencing low population growth levels. Therefore, we still have a remarkable opportunity to safeguard the species and places that form the ecological fabric of the Granite State. But how do we do it? The establishment of a system of ecological reserves, in concert with good management of commercial timberlands, wildlife populations, and watersheds, is a vital step in protecting the biological diversity of New Hampshire over the long term.

Program Goals
The Living Legacy Project has the following goals to help achieve its mission:
- Guide land protection and public and private investment in
biodiversity conservation by fostering the development of new conservation
tools (e.g., ecological assessments) and by sustaining and enhancing existing
programs (e.g., LCHIP).
- Measure and acknowledge our success in conserving
biodiversity by working with state agencies to develop and sustain a
cost-effective, practical tracking mechanism.
- Enhance the capacity for NH's natural resource agencies to
conduct field inventories and research and to manage the data to make it more
useful and available for conservation planning.
- Increase public understanding of the values of biodiversity
and opportunities for conserving these values.
- Continue the LLP as an effort based on and integrated into
existing programs, agencies, and conservation lands.
- Assess the impacts of particular land uses and activities on biodiversity and assess the impacts of biodiversity conservation on particular land uses.

Biodiversity Primer
Biological diversity, or biodiversity, is the variety and variability of
all living organisms. This variety includes the diversity of plants, animals,
fungi, algae, bacteria, and other microorganisms, their genetic variability,
the natural communities in which they live, and the processes and interactions
that weave the biological and physical elements of the planet into a complex
web. By separating the concept into several layers - genetic, species,
community, ecosystem, and taxonomic diversity - we can study this complexity
and gain a better understanding of biodiversity.
Species diversity is
the most easily understood and commonly used measure of biodiversity, although
the terms are not synonymous. A species is a group of individuals capable of
breeding with each other, but unable to breed successfully with any other
group. In New Hampshire, more than 15,000 different species of organisms have
been identified. Species range from the rare (peregrine falcon, cobblestone
tiger beetle, lynx, and squirrel corn) to the common (American robin, black
flies, white-tailed deer, and sugar maple). Much of New Hampshire's species
diversity is composed of beetles, bugs and other insects
(pie chart) .
There are 11,000 known insect
species, and little is known about many of them. Nearly 3,000 species of
flowering plants, ferns, fungi, algae, bryophytes, and lichens occur in the
state.
The number of species in a particular area, or species
richness, is one measure of species diversity. This measure does not take into
account the fact that not all species are equally abundant; many are uncommon,
some are common. Species richness at the local level contributes to
biodiversity at the state or regional level. Loss of a species reduces
biodiversity. This is why rare species, which are more susceptible to
extinction, often receive special attention.
Although the addition of
new species will increase an area's biodiversity in the short term, the spread
of non-native species can ultimately cause a decline in native species
diversity. A native species is one that occurs naturally in a particular area
without human activity to assist its introduction. Since non-native species are
often introduced without natural predators or other controls, they may
outcompete native species for resources, such as space or food. Purple
loosestrife, ring-necked pheasant, mute swan, brown trout, and gypsy moth are
just a few of New Hampshire's non-native species. Within the state, species can
be native to one area and non-native to another. For example, brook trout are
native to some lakes but they are non-native to others into which they were
introduced.
Genetic diversity refers to variation in genetic makeup
among individuals of the same species. Genes are master codes that govern
structure or behavior of each organism. Genetic diversity occurs within
populations. For example, individual trees in a stand of pitch pine may be
genetically different from each other. Variation within the gene pool increases
the chance that a species will adapt to changing environmental conditions.
Genetic diversity also occurs between populations. The scrubby pitch pines that
grow in areas that burn frequently are genetically different from the straight
ones that grow in areas where fire is infrequent. Between-population genetic
diversity is sometimes recognized as subspecies, which are populations of the
same species whose individuals look distinctly different. A species that is
rare in New Hampshire, yet common elsewhere, may be an important element of the
region's biodiversity, since populations in New Hampshire may be genetically
distinct from other populations.
Beyond the species level in the
hierarchical system of classification used by taxonomists are the more
inclusive groups of genus, family, order, class, and phylum. The variety at
these higher levels (for example, the number of families represented in a
geographic area) is termed taxonomic diversity. A plant community with six tree
species - red oak, white pine, red maple, paper birch, shagbark hickory, and
American beech - has six genera and five families. It has greater taxonomic
diversity than another community with six species - pitch pine, red pine, white
pine, American beech, red oak and white oak - which represent only three genera
and two families.
Biologically, a community is a group of species
(plants, animals, fungi, microorganisms) that occur together in a particular
area. Alpine bogs, spruce-fir forests, Atlantic white cedar swamps and coastal
sand dunes are all examples of the 130 types of biological communities
identified in New Hampshire. An ecosystem is a community or group of
communities plus their physical environment (soils, geology, climate, etc.). A
landscape is a large scale unit of the earth's surface that supports a mosaic
of different ecosystems. Community or ecosystem diversity is the variety of
communities or ecosystems within a larger landscape. Different communities or
ecosystems contain different species and often differ in the processes that
occur within them.
Change within these levels of biodiversity is
constantly occurring at different scales of time and space. Natural and
human-induced change in biodiversity is inevitable. Factors that bring about
change in biological diversity range from local disturbances, such as a tree
fall, to shifts in global climatic conditions.
To understand the
dynamic nature of biodiversity one must focus on ecosystems and larger
landscapes, rather than just individual species. This focus considers the full
complexity of natural systems - the ecological, evolutionary, physical, and
human processes that affect and sustain life.

Why is Biodiversity Important?
Biological diversity benefits us in many ways. The reasons for maintaining
biodiversity are varied and often difficult to quantify, yet all contribute to
a greater quality of life.
Direct Benefits to Humans
Biodiversity is an economic resource, a reservoir of materials for use in
agriculture, medicine and industry. Worldwide, tens of thousands of plants and
animals are used by humans. Plants are sources of vegetables, fruits, grains,
spices, herbs, oils, beverages, drugs, fuel, fibers, rubber, timber, and more.
New Hampshire's agricultural crops alone bring in nearly $100 million yearly.
Despite the obvious economic value of biodiversity, fewer than 1 percent of all
plants and animals have been examined for possible human benefit.
The
link between biodiversity and our own health is clear. Most medicines used
today originate from studies of wild species. Aspirin comes from a willow tree,
penicillin from a common fruit mold. A chemical from the saliva of leeches
dissolves blood clots during surgery. The Pacific yew, a tree growing in the
northeast U.S., contains taxol used to treat ovarian cancer. The rosy
periwinkle, found in Madagascar, contains a chemical used in treating Hodgkin's
disease. Plant-derived drugs have yielded the U.S. pharmaceutical industry
billions of dollars. Hundreds of other plants are used as herbal medicines.
In addition to agricultural and medicinal values, biodiversity
influences a region's appeal to tourists. Each year millions of Americans take
trips primarily to view, photograph, hunt, or study nature, and spend billions
of dollars on trip-related expenses. Americans who watch birds spend $5.2
billion annually on their hobby - and support 200,000 jobs! In New Hampshire,
88 percent of the population participates in wildlife-related activities.
Retail sales for birdwatching and birdfeeding in New Hampshire total $57
million. Hunting and fishing bring in millions of dollars more to local
communities.
A diversity of living things performs a variety of
services for us, including pollination of fruit and vegetable crops, and
control of pests, at no cost to human society. The growing field of "integrated
pest management" relies on natural biodiversity as a source of new pest control
agents that are less damaging to the environment and human health, and cost
less than traditional control measures. For example, in an effort to control
the invasive non-native plant, purple loosestrife, American biologists examined
dozens of insect species that feed on loosestrife in its natural range in
Europe. A few had potential to serve as control agents in North America and one
insect has been released in the U.S. and Canada. Without a diversity of
potential biological control agents to choose from, control of loosestrife
might have been possible only with great expense and negative effects on the
environment.
Biodiversity Supports Life
As part of
the biological community, humanity depends on natural systems for survival.
Living organisms enrich the soil that grows our food, and generate the oxygen
we breathe. The diversity of life forms and interactions between them are the
reason earth's systems function so efficiently and effectively. The integrity
of these systems is a function of biodiversity.
A diversity of
organisms thrives by processing natural and human wastes. Organic materials
like leaf litter on the forest floor, agricultural wastes, and human sewage,
are broken down by microbial organisms. Polluted waters are purified through
the actions of natural microbial communities. As little is known about how many
microbial species are involved in these processes or what their specific roles
are, protection of these organisms is important.
Some organisms play
key roles in the recovery of natural systems from disturbance. For example,
clearcutting of northern hardwood forest liberates nutrients that might be lost
from the ecosystem were it not for pin cherry, a short-lived tree with little
direct economic importance. Pin cherry seeds germinate when soil is disturbed
and the seedlings grow rapidly, sopping up nutrients that would otherwise be
leached or eroded.
The structure of natural systems is often strongly
influenced by species that are not particularly abundant or conspicuous. Such
"keystone species" typically control their prey populations or modify their
physical habitat, and thus affect the ecosystem's physical appearance or
species composition. Pin cherry is an example. In another case, the species
diversity of the intertidal community in the Pacific Northwest is largely
maintained by one species of sea star. This sea star preys on mussels that
would otherwise outcompete most other species in the community. Some scientists
believe that the American lobster is a keystone species in the Gulf of Maine.
Loss of Biodiversity
Humans have lived in New
Hampshire for a thousand or more years. The effects of people on the natural
environment have increased along with the growing population. In the last two
hundred years at least six species of mammals and birds that once occurred in
New Hampshire and its adjacent waters have disappeared forever. These are
Labrador duck, sea mink, great auk, passenger pigeon, heath hen, and scrag
whale. The reasons for their extinctions are complex, but human activity played
an important role.
As humans change habitats and reduce biodiversity,
we are faced with many questions about how the loss of species will affect the
ecological systems they inhabit. Moreover, there may be losses to future
generations of people, limiting options for new food sources or cures to deadly
diseases.
Aldo Leopold described one of the most compelling reasons
for biodiversity conservation in the phrase, "To keep every cog and wheel is
the first precaution of intelligent tinkering." In New Hampshire scientists are
still discovering and naming the "cogs and wheels" of our biological diversity.
Conserving biodiversity is part of our obligation to future generations. We
want to be sure that even with our tinkering, the world our children inherit
has all the necessary "cogs and wheels."

Project History
In 1994, the Northern Forest Lands Council submitted their report Finding Common Ground, outlining the Council's recommendations for reinforcing the traditional patterns of land ownership and uses of the northern forest. As part of its findings, the Council highlighted the importance of biodiversity conservation: "the Council believes that maintaining the region's biodiversity is important in and of itself, but also as a component of stable forest-related economies, forest health, land stewardship, and public understanding." The Council recommended that states "develop a process to conserve and enhance biodiversity across the landscape". The Council provided guidelines for this process including:
- provide landowners with information about how to conserve
biodiversity on their land through both forest management practices and
establishment of ecological reserves
- use scientific assessment and analysis to create ecological reserves as one component of state public land acquisition and management programs.
In 1998, the Steering Committee produced two documents:
- An Assessment of the Biodiversity of New Hampshire with Recommendations for Conservation Action
- Protecting New Hampshire's Living Legacy: a blueprint for biodiversity conservation in the Granite State.
From 1998-2000, Project partners worked with others to urge
the New Hampshire Legislature to establish and fund a new land conservation
program, the Land and Community Heritage Investment Program (LCHIP). These
efforts resulted in funding for LCHIP and recognition that ecological values,
among others, are part of the state's heritage worth protecting through LCHIP.
Since 2000, the Project Coordinator and Core Team have moved the ERSP
through a refinement of the scientific criteria for identifying areas of
greatest ecological value and a pilot phase to test and evaluate the criteria
and project principles. Project partners unveiled a new name in May 2002 - NH
Living Legacy Project (LLP). The new name more fully represents the Project
mission: to establish and support a well-coordinated, comprehensive system of
public and private lands voluntarily dedicated to protecting the full spectrum
of biological diversity in the state.
