The relationship between forests and climate change is intricate. On the one hand forests can mitigate climate change by absorbing carbon, while on the other they can contribute to climate change if they are degraded or destroyed. In turn climatic changes may lead to forest degradation or loss - which exacerbates climate change further.

A protected area is defined as: "A clearly defined geographical space, recognized, dedicated and managed, through legal or other effective means, to achieve the long-term conservation of nature with associated ecosystem services and cultural values" (Dudley, 2008). Forest protected areas help conserve ecosystems that provide habitat, shelter, food, raw materials, genetic materials, a barrier against disasters, a stable source of resources and many other ecosystem goods and services - and thus can have an important role in helping species, people and countries adapt to climate change. By virtue of their protective status, these forests should remain free from destructive human intervention. They can thus continue to serve as a natural storehouse of goods and services into the future.

Today climate change is one of the main emerging threats facing biodiversity. Up to a quarter of mammal species (about 1 125) (IPCC, 2002) and about 20 percent of bird species (about 1 800) (IPCC, 2007) are at risk of global extinction because of climate change.

Protected areas that were set up to safeguard biodiversity and ecological processes are likely to be affected by climate change in a number of ways. Climate change is expected to cause species to migrate to areas with more favourable temperature and precipitation. There is a high probability that competing, sometimes invasive species, more adapted to a new climate, will move in. Such movements could leave some protected areas with a different habitat and species assemblage than they were initially designed to protect. For example, Scott (2005) found that a stated objective of Prince Albert National Park in Saskatchewan, Canada, to protect ecological integrity "for all time",is unrealistic, as all possible climate scenarios project the eventual loss of boreal forests and their related bio­diversity in that area. Climate change is expected to lead to disease outbreaks as pest species may become more resistant or survive longer and new pest species may invade protected areas. For instance, Pounds et al. (2006) have traced the much publicized extinction of the Monteverde harlequin frog (Atelopus sp.) and the golden toad (Bufo periglenes) in the Monteverde forest of Costa Rica nearly two decades ago to warming in the American tropics which is thought to have favoured a particular fungus that infected the amphibians. Climate change is also likely to lead to a higher incidence of fire in some situations and floods in others (IPCC, 2007).

In many cases, the negative effects of climate change on protected areas will be compounded by other stresses, notably those caused by humans, for example through overconsumption, pollution or encroaching urbanization. Biodiversity in protected areas that may already be vulnerable because of these human threats may be more quickly or more severely affected by climate change.

With these and other likely changes, the management of existing protected areas will need to be modified if they are to fulfil their biodiversity conservation role as well as support adaptation to climate change.

This article explores the importance of forest protected areas for ecological, social and economic purposes, drawing on examples from the work carried out around the globe by the World Wide Fund for Nature (WWF) in the context of climate change. It focuses on the broader spatial context and the landscapes within which protected areas are found. It then proposes a range of management and policy responses to ensure that forest protected areas can continue to support biodiversity conservation in the face of climate change.In a changing climate, protected areas will take on added importance as safe havens for biodiversity by offering good-quality habitats less vulnerable to climate extremes (African buffalo, Syncerus caffer - a species susceptible to drought conditions - in Ngorongoro Conservation Area, United Republic of Tanzania)A.

IMPORTANCE OF FOREST PROTECTED AREAS IN THE FACE OF CLIMATE CHANGEProtected areas have been recognized for several decades as an essential tool for conserving biodiversity. The impacts of climate change now give them a renewed role as adaptation tools for a changing climate. Their importance in this respect is threefold:
  • in supporting species to adapt to changing climate patterns and sudden climate events by providing refuges and migration corridors;
  • in protecting people from sudden climatic events and reducing vulnerability to floods, droughts and other weather-induced problems;
  • indirectly, in supporting economies to adapt to climate change by reducing the costs of climate-related negative impacts.
Ecological roleThe world now has over 100 000 protected areas, of which the terrestrial ones cover 12.2 percent of the earth's surface (UNEP-WCMC, 2008). Protected areas can be among the most effective tools for protecting species from extinction and from the impact of human-induced threats. If well planned and managed, they can contribute to biodiversity conservation by:
  • representing distinct natural communities within conservation landscapes and protected areas networks;
  • maintaining ecological and evolutionary processes that create and sustain biodiversity;
  • maintaining viable populations of species;
  • conserving blocks of natural habitat large enough to be resilient to large-scale disturbances and long-term changes (Noss, 1992).

In the creation of most protected areas and in the identification of sites that achieve targets for habitat and species representation to date, a relatively constant climate has been assumed (Hannah et al., 2007). However, as the climate changes, plans and assumptions about protected areas need to be reconsidered (McCarty, 2001). Areas for future conservation efforts need to be assessed in the face of different climate change scenarios, and the current protected area network needs to be reviewed to ensure that it can deliver intended conservation results and help mitigate negative climate change impacts.

In a changing climate, protected areas will take on added importance as safe havens for biodiversity by offering good-quality habitats less vulnerable to climate extremes, by providing refuges for threatened species and by conserving important gene pools. It will also become more important to protect reference landscapes - ecosystems on which restoration planning is based, and which provide a basis for evaluating the success of restoration (Sayer, 2005).

Networks of protected areas within large-scale landscapes will help accomplish the fourth point above, providing resilience to climate change. Landscape planners can help biodiversity adapt to changing conditions by carefully defining and managing connections or corridors between protected areas, removing or preventing barriers such as roads or monoculture plantations of trees or agricultural crops and creating "stepping stones" for particular species (Figure).

To ensure the survival of priority plant and animal species targeted for conservation, it will be important to obtain new information on their:

  • sensitivity to disruptions (e.g. by roads, agriculture, settlements);
  • sensitivity to edge effect, i.e. the ratio between perimeter and area (generally the greater the ratio, the greater the sensitivity to disturbances from outside the perimeter);
  • food specialization and availability;
  • habitat quality required (e.g. primary or secondary forest);
  • movements, particularly when under stress;
  • migration habits and routes;
  • relationship to local human communities and to other species (Mansourian, 2006).

This information can then be overlaid with predicted climate scenarios so that action can be taken to safeguard biodiversity.

For example, because of the added threat of climate change to African elephants and their habitat, the implementation of the WWF Species Action Plan for African elephants (Stephenson, 2007) will include climate vulnerability assessments for elephant populations using available assessment tools (Hannah, 2003). The results will be used to develop and implement climate change adaptation strategies for elephant landscapes identified as being at high risk. The Amazon's unique biodiversity is also expected to be under significant threat from climate change; a loss in the viability of numerous plant species, specifically in the northeastern Amazon, is expected by 2095 under all climate scenarios (Miles, 2002).Protected areas in a landscape

Social roleProtected areas may provide ecosystem services such as drinking water, carbon storage and soil stabilization; harbour sacred sites for different faith groups; and hold important gene reservoirs of value in medicine, agriculture and forestry. In the face of climate change these roles all become more critical to enhance the adaptive capacity of local people to cope with climate change (Simms, 2006).

Protected areas, by helping to maintain natural ecosystems, can contribute to physical protection against major disasters, which are predicted to be on the rise with climate change (Scheuren et al., 2007). Although the scale of disasters generally depends on an aggregation of factors (e.g. building regulations, land use), in many cases ecosystem maintenance and forest protection can greatly reduce their impacts. Coastal mangroves, coral reefs, floodplains and forests may buffer land, communities and infrastructure against natural hazards. For example, during the Indian ocean tsunami in 2004, vegetation-covered coastal sand dunes at Yala and Bundala National Parks in Sri Lanka completely stopped the waves and protected the land behind them (Caldecott and Wickremasinghe, 2005). Some protected areas also provide an opportunity for active or passive restoration of traditional land use practices such as agroforestry and crop terracing, which may help mitigate the impacts of extreme weather events in arid lands, for example by reducing the risk of erosion and by maintaining soil structure (Stolton, Dudley and Randall, 2008).

In addition, protected area management can help empower marginalized human populations or community groups. Alternative forms of protected area governance such as community conservation or joint management, for example, are being implemented to reduce conflicts over land and to promote long-term maintenance of protected areas for provision of benefits to stakeholders. A case in point is the "Parks with People" policy developed in Bolivia in 2005 to engage indigenous communities in management of protected areas (Peredo-Videa, 2008).Protection of coastal mangroves can help ensure their provision of physical defence against major disasters, which are predicted to be on the rise with climate change (Sundarbans National Park, Bangladesh)FAO/FO-0316/T. Loosli

Economic roleIf a country's natural habitat is destroyed by climate change impacts, its economy will suffer. A recent study (Dasgupta et al., 2007) found that the gross domestic product (GDP) of a number of countries, led by Viet Nam, could be negatively affected by sea level rise, saltwater intrusion and natural disasters attributed to climate change. In helping to protect natural habitat, protected areas indirectly help to protect the national economy.

In addition, protected areas can provide a direct means of enhancing revenue, notably through tourism, but also through the valuable products they harbour and the services they provide. For example, Guatemala's Mayan Biosphere Reserve provides employment for over 7 000 people and generates an annual income of approximately US$47 million (PCLG, 2002). In Madagascar, a study of 41 reserves found that the economic rate of return of the protected area system was 54 percent, essentially from watershed protection and to a lesser extent from ecotourism (Naughton-Treves, Buck Holland and Brandon, 2005). Thus, protected areas provide a safety net which can be valuable in times of stress, such as extreme climate events.

The loss of protected areas may lead to significant costs, for example infrastructure damage and human tragedy caused by desertification or tsunamis, or to loss of revenue, from tourism for instance. Furthermore, deforestation of major forest blocks, such as the Amazon, is thought to have an impact on global rainfall, which in turn affects agriculture and therefore the livelihoods of millions of people (Nepstad, 2007). Protected areas therefore not only help protect biodiversity, but also indirectly contribute to the planet's food security.The potential loss of protected areas may lead to loss of revenue, from tourism for example (Iguazu Falls National Park, on the border between Brazil and Argentina, one of the top destinations in South America with nearly 2 million tourists a year)A.

Wild life and forest should be conserved because they are a important part of our lives and mother earth. These days the forests and wild animals are reducing gradually day by day. So to keep a control on the reducing number OS trees and wild animals we should conserve the wild life and forests because if it isn't it will be turned into something elce like flats or shops i hope this helped you
