Such services are often overlooked by humanity, due to the ecosystem from which they originate being far from urbanized areas. The contamination of ecosystem services within a designated area ultimately degrades their use for society. For example, the protection of a water body inherently protects that water body's microorganisms and their ability to adequately filter pollutants and pathogens, ultimately protecting water quality itself. Therefore,

The soliciting of protected areas may require regulation to the level of meeting demands for food, feed, livestock and fuel, and the legal enforcement of not only the protected area itself but also 'buffer zones' surrounding it, which may help to resist destabilisation. Protected area downgrading, downsizing, and degazettement (PADDD) Protected area downgrading, downsizing, and degazettement (PADDD) events are processes that change
4860-713: The initial goal of protected areas, though many illegal activities are often overlooked. There is increasing pressure to take proper account of human needs when setting up protected areas and these sometimes have to be "traded off" against conservation needs. Whereas in the past governments often made decisions about protected areas and informed local people afterwards, today the emphasis is shifting towards greater discussions with stakeholders and joint decisions about how such lands should be set aside and managed. Such negotiations are never easy but usually produce stronger and longer-lasting results for both conservation and people. In some countries, protected areas can be assigned without

Protected Areas alleviate climate change effects in a variety of ways: The objective of protected areas is to conserve biodiversity and to provide a way for measuring the progress of such conservation. Protected areas will usually encompass several other zones that have been deemed important for particular conservation uses, such as Important Bird Areas (IBA) and Endemic Bird Areas (EBA), Centres of Plant Diversity (CPD), Indigenous and Community Conserved Areas (ICCA), Alliance for Zero Extinction Sites (AZE) and Key Biodiversity Areas (KBA) among others. Likewise,

Out of the aforementioned flowering plant taxa, about 171 species of grass and 140 species of orchids have been recorded within the park. The grasses are found in the open grasslands found on the edges of the water bodies and montane habitats where fire resistant vegetation grows and dense grasses like elephant grass are found. Various herbivores such as sambar, Asian elephants, gaur and wild boar have been observed to graze here. Forests found here are composed of deciduous, evergreen and semi evergreen trees like teak , rosewoods , terminalia , sandalwoods , mangoes , jamun , tamarind , banyans , sacred fig , kino tree , bamboos , Diospyros bourdillonii , Hopea parviflora , Dipterocarpus indicus , Semecarpus travancoricus and
5832-465: The rest occurs during the northeast monsoon between October and December. Summers are warm with some precipitation in April and winters are cold. The park is made up of tropical evergreen, semi-evergreen and moist deciduous forests , montane grasslands , montane savannas , man-made stands of eucalyptus , wetlands, and lake and river ecosystems . A total of 1965 taxa (species and infraspecific) of flowering plants have been collected and described from
5913-568: The spring gentian, are adapted to the alkaline conditions found on calcium -rich chalk and limestone , which give rise to often dry topographies such as limestone pavement . As for their growth habit , the flowering plants range from small, soft herbaceous plants , often living as annuals or biennials that set seed and die after one growing season, to large perennial woody trees that may live for many centuries and grow to many metres in height. Some species grow tall without being self-supporting like trees by climbing on other plants in
5994-821: The standards and terminology of protected areas took place at the International Conference for the Protection of Fauna and Flora in London. At the 1962 First World Conference on National Parks in Seattle the effect the Industrial Revolution had had on the world's natural environment was acknowledged, and the need to preserve it for future generations was established. Since then, it has been an international commitment on behalf of both governments and non-government organisations to maintain
6075-653: The term ' other effective area-based conservation measures ' was defined as "a geographically defined area other than a Protected Area, which is governed and managed in ways that achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity, with associated ecosystem functions and services and where applicable, cultural, spiritual, socio-economic, and other locally relevant values." Other effective area-based conservation measures complement protected areas across landscapes, seascapes, and river basins. Protected areas and other effective area-based conservation measures are referenced together in Target 3 of
6156-506: The tiger, dhole ( Cuon alpinus ), Binturong , clouded leopard and Tibetan fox ( Vulpes ferrilata ) . Also found to be prevalent were the large herbivore species: Asiatic water buffalo Bubalus arnee , golden langur , musk deer , and Asian elephant . The maintenance of these charismatic megafauna and other threatened species can be attributed to the intensity of Bhutan's management of its protected areas and its local communities' commitment to preserving them. The National Heritage List
6237-527: The western slopes of Mount Lebanon’s mountain range and has passed laws to protect environmental sites at the national level, including nature reserves, forests, and Hima (local community-based conservation), with some of these sites having acquired one or more international designations: There are three biosphere reserves in Lebanon that have been designated by the UNESCO : O Parks, Wildlife, and Recreation
6318-559: The world's staple calorie intake, and all three plants are cereals from the Poaceae family (colloquially known as grasses). Other families provide important industrial plant products such as wood , paper and cotton , and supply numerous ingredients for beverages , sugar production , traditional medicine and modern pharmaceuticals . Flowering plants are also commonly grown for decorative purposes , with certain flowers playing significant cultural roles in many societies. Out of
6399-576: The world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; this has been adopted by the European Union in its Biodiversity Strategy for 2030 , Campaign for Nature which promoted the goal during the Convention on Biodiversity 's COP15 Summit and the G7 . In December 2022, Nations have reached an agreement with
6480-483: Was coined in the form "Angiospermae" by Paul Hermann in 1690, including only flowering plants whose seeds were enclosed in capsules. The term angiosperm fundamentally changed in meaning in 1827 with Robert Brown , when angiosperm came to mean a seed plant with enclosed ovules. In 1851, with Wilhelm Hofmeister 's work on embryo-sacs, Angiosperm came to have its modern meaning of all the flowering plants including Dicotyledons and Monocotyledons. The APG system treats
6561-552: Was included in Project Tiger, a Central Government initiative, and was renamed the Periyar Tiger Reserve in 1978. Periyar National Park lies in the middle of a mountainous area of the Cardamom Hills . In the north, the boundary commences from the point nearest to the Medaganam in the interstate boundary up to Vellimalai. To the east the boundary follows the inter-state boundary from Vellimalai to Kallimalai Peak (1615 m) it
