"Human
dimensions" with respect to habitat restoration refers to how people
use, value, and benefit from the restoration of degraded habitats.
The human dimension of restoration is often at the root of our
desire to restore habitat in the first place.
Restoration provides a host of socioeconomic
benefits - from property
protection to improved water quality to restored aesthetics. While
natural systems and non-human species certainly benefit from habitat
restoration, people often benefit as well.
Whether through legislation, volunteers, or private/semi-private
funding initiatives, restoration actions are driven by a need to
correct some form of human-induced environmental impairment. Corrective
action is often determined by social perceptions grounded in environmental
values.
"While a mechanistic ecology denies any commitment to values,
restoration ecology represents a technique for basic research
that explicitly links ecology to values such a beauty, community,
and the well-being of the ecosystem." (Jordan 2000)
A. Human Dimensions Defined
Human dimensions refers to human activities that relate to the
individual, society, or the environment.
Human dimensions includes a suite of social science considerations:
- cultural change and influences,
- demographics,
- psychology,
- equity issues and ethics,
- economic structures and market forces,
- technological change,
- political-social institutions and their interactions, and
- social values.
B. Human management of natural systems
Today, nearly all resource management is based
on the intensity of human interaction with the environment. We
do not manage species and habitats so much as we manage human interactions
with and impacts on natural systems. Human activities can alter
every physical component of an ecosystem. Our past inability to
predict and prevent the adverse consequences of our actions has
resulted in significant ecological harm. Our past actions have
also created the need for the emerging science of ecological restoration.

Ecological restoration is rarely perfect. Nature's sequences of
ecological, geochemical, and climatological processes are extraordinarily
complex. Human attempts to replicate these sequences present a
challenge.
Restoration is also challenging because it must be performed within
the context of human understandings and limitations. It is a quickly
evolving science. Techniques are increasingly becoming standardized
and are resulting in success stories. And participation in this
new frontier is often marked by personal satisfaction and excitement
by laypeople and professionals alike.
Thousands of restoration
projects are carried out in North America
every year. The National Oceanic and Atmospheric Administration
(NOAA) alone facilitates several hundred projects annually.
NOAA focuses on coastal and marine areas. Restoration actions
in these areas address habitats such as tidal marshes, wetlands,
coral reefs, mangroves, seagrass beds, and kelp forests, to name
a few. These habitats provide homes for marine mammals, foraging
and nursery grounds for fish and shellfish, and nesting and migration
corridors for birds. Coastal habitats provide services to people
as well, such as protection from wind, waves, and flooding, and
socio-economic opportunities via tourism, commercial, and recreational
industries.
C. Environmental Stewardship Ethic
Environmental stewardship encompasses our knowledge, attitudes,
values, ethics, perceptions, and behaviors toward environmental
renewal.
In a society as diverse as ours, environmental values vary widely
and shift within and across generations. For example, filling wetlands
to increase acreage for agriculture or urban development and damming
rivers to improve commerce and transportation were common practices
in the early and mid- 20th century. Past generations seemed to
give little consideration to the ecological consequences of these
actions. Today, such practices are rare and may be viewed as socially
or legally unacceptable.
Because actions that either enrich or degrade the environment
are carried out by communities, building a deeply committed constituency
(stewards) for future protection and conservation of intact landscapes
is vital to the success of habitat restoration. Community-based
restoration offers one way to approach the enormous task of restoring
degraded ecosystems while helping citizens develop an environmental
stewardship ethic.
When communities mobilize by participating in restoration they
naturally develop a relationship with their immediate environment.
This new relationship offers the opportunity for lasting changes
in the way an individual perceives and values the environment.
If this perception translates into behavior that benefits the natural
environment, an environmental steward is born.
Organizations sponsoring habitat restoration often seek to build
communities that will energetically support habitat protection
and conservation. Activating an individual's passion for positive
environmental change, thereby helping him or her to become an environmental
steward, is important to the long-term success of habitat restoration.
Environmental stewardship is evidenced in activities such as attending
public meetings related to restoration proposals, actively engaging
in responsible environmental behaviors (e.g., recycling or using
mass transit), contributing money to an environmental organization,
or volunteering to monitor and evaluate restoration projects.
Community-based habitat restoration offers a unique opportunity
to connect citizens to their environment and foster a sense of
environmental stewardship. Through hands-on habitat restoration,
individuals develop a special relationship with a particular part
of the landscape or seascape and often come to realize that they
can positively influence complex ecosystems in small but significant
ways. These environmental stewards may also realize they can, by
extension, enhance the larger environment of their watershed, their
region, and the planet as a whole.
