Cyperaceae
–
The Cyperaceae are a family of monocotyledonous graminoid flowering plants known as sedges, which superficially resemble grasses and rushes. The family is large, with some 5,500 known species described in about 90 genera and these species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be growing in almost all environments, many are associated with wetlands. Ecological communities dominated by sedges are known as sedgelands, features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections and leaves that are spirally arranged in three ranks. Some well-known sedges include the chestnut and the papyrus sedge. This family also includes cotton-grass, spike-rush, sawgrass, nutsedge or nutgrass, and white star sedge

Poaceae
–
Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses. Poaceae includes the cereal grasses, bamboos and the grasses of natural grassland and cultivated lawns, Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath, with ca 780 genera and around 12,000 species, Poaceae are the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. Grasslands such as savannah and prairie grasses are dominant are estimated to constitute 40. 5% of the land area of the Earth, excluding Greenland. Grasses are also an important part of the vegetation in many habitats, including wetlands, forests. Though commonly called grasses, seagrasses, rushes, and sedges fall outside this family, the rushes and sedges are related to the Poaceae, being members of the order Poales, but the seagrasses are members of order Alismatales. The name Poaceae was given by John Hendley Barnhart in 1895, based on the tribe Poeae described in 1814 by Robert Brown, the term is derived from the Ancient Greek πόα. Grasses include some of the most versatile plant life-forms, a cladogram shows subfamilies and approximate species numbers in brackets, Before 2005, fossil findings indicated that grasses evolved around 55 million years ago. Recent findings of grass-like phytoliths in Cretaceous dinosaur coprolites have pushed this back to 66 million years ago. In 2011, revised dating of the origins of the rice tribe Oryzeae suggested a date as early as 107 to 129 Mya, a multituberculate mammal with grass-eating adaptations seems to suggest that grasses were already around at 120 mya. This separation occurred within the short time span of about 4 million years. Grass leaves are always alternate and distichous, and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem, the leaf blades of many grasses are hardened with silica phytoliths, which discourage grazing animals, some, such as sword grass, are sharp enough to cut human skin. A membranous appendage or fringe of hairs called the ligule lies at the junction between sheath and blade, preventing water or insects from penetrating into the sheath, flowers of Poaceae are characteristically arranged in spikelets, each having one or more florets. The spikelets are further grouped into panicles or spikes, the part of the spikelet that bears the florets is called the rachilla. A spikelet consists of two bracts at the base, called glumes, followed by one or more florets, a floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The flowers are usually hermaphroditic—maize being an important exception—and anemophilous or wind-pollinated, the perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea, these are generally interpreted to be modified sepals. This complex structure can be seen in the image on the right, the fruit of grasses is a caryopsis, in which the seed coat is fused to the fruit wall

Moss
–
Mosses are small flowerless plants that typically grow in dense green clumps or mats, often in damp or shady locations. Although some species have conducting tissues, these are poorly developed. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores and they are typically 0. 2–10 cm tall, though some species are much larger. Dawsonia, the tallest moss in the world, can grow to 50 cm in height, mosses are commonly confused with lichens, hornworts, and liverworts. Lichens may superficially look like mosses, and have names that include the word moss. This contrasts with the pattern in all plants, where the diploid sporophyte generation is dominant. Mosses are now classified on their own as the division Bryophyta, the main commercial significance of mosses is as the main constituent of peat, although they are also used for decorative purposes, such as in gardens and in the florist trade. Traditional uses of mosses included as insulation and for the ability to absorb liquids up to 20 times their weight, botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are small plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide. They differ from plants in lacking water-bearing xylem tracheids or vessels. As in liverworts and hornworts, the gametophyte generation is the dominant phase of the life cycle. This contrasts with the pattern in all plants, where the diploid sporophyte generation is dominant. Mosses reproduce using spores, not seeds, and have no flowers, Moss gametophytes have stems which may be simple or branched and upright or prostrate. Their leaves are simple, usually only a layer of cells with no internal air spaces. They do not have roots, but have threadlike rhizoids that anchor them to their substrate. Mosses do not absorb water or nutrients from their substrate through their rhizoids and they can be distinguished from liverworts by their multi-cellular rhizoids. Spore-bearing capsules or sporangia of mosses are borne singly on long, unbranched stems, thereby distinguishing them from the polysporangiophytes, the spore-bearing sporophytes are short-lived and dependent on the gametophyte for water supply and nutrition. Also, in most mosses, the capsule enlarges and matures after its stalk elongates

Lichen
–
A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi in a symbiotic relationship. The combined lichen has properties different from those of its component organisms, Lichens come in many colours, sizes, and forms. The properties are sometimes plant-like, but lichens are not plants, Lichens may have tiny, leafless branches, flat leaf-like structures, flakes that lie on the surface like peeling paint, or other growth forms. A macrolichen is a lichen that is either bush-like or leafy, here, macro and micro do not refer to size, but to the growth form. Common names for lichens may contain the word moss, and lichens may superficially look like and grow with mosses, Lichens do not have roots that absorb water and nutrients as plants do, but like plants, they produce their own food by photosynthesis. When they grow on plants, they do not live as parasites, Lichens occur from sea level to high alpine elevations, in many environmental conditions, and can grow on almost any surface. Lichens are abundant growing on bark, leaves, mosses, on other lichens and they grow on rock, walls, gravestones, roofs, exposed soil surfaces, and in the soil as part of a biological soil crust. Different kinds of lichens have adapted to survive in some of the most extreme environments on Earth, arctic tundra, hot dry deserts, rocky coasts and they can even live inside solid rock, growing between the grains. It is estimated that 6% of Earths land surface is covered by lichen, there are about 20,000 known species of lichens. Some lichens have lost the ability to reproduce sexually, yet continue to speciate, Lichens may be long-lived, with some considered to be among the oldest living things. They are among the first living things to grow on fresh rock exposed after an event such as a landslide, the long life-span and slow and regular growth rate of some lichens can be used to date events. In American English, lichen is pronounced the same as the verb liken, in British English, both this pronunciation and one rhyming with kitchen /ˈlɪtʃən/) are used. Lichens grow in a range of shapes and forms. The shape of a lichen is determined by the organization of the fungal filaments. The nonreproductive tissues, or vegetative body parts, is called the thallus, Lichens are grouped by thallus type, since the thallus is usually the most visually prominent part of the lichen. Thallus growth forms typically correspond to a few basic internal structure types, Common names for lichens often come from a growth form or color that is typical of a lichen genus. When a crustose lichen gets old, the center may start to crack up like old-dried paint, old-broken asphalt paving and this is called being rimose or areolate, and the island pieces separated by the cracks are called areolas. The areolas appear separated, but are connected by an underlying prothallus or hypothallus, when a crustose lichen grows from a center and appears to radiate out, it is called crustose placodioid
5.
Tree line
–
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and in frigid environments, beyond the tree line, trees cannot tolerate the environmental conditions. The tree line should not be confused with a lower timberline or forest line, at the tree line, tree growth is often sparse and stunted, with the last trees forming densely matted bushes, known as krummholz. The tree line, like other natural lines, appears well-defined from a distance. Trees grow shorter towards the inhospitable climate until they stop growing. The climate above the line of mountains is called an alpine climate. In the northern hemisphere treelines on north-facing slopes are lower than on south-facing slopes because the increased shade on north-facing slopes means the snowpack takes longer to melt and this shortens the growing season for trees. In the southern hemisphere, the slopes have the shorter growing season. The alpine tree line boundary is seldom abrupt, it forms a transition zone between closed forest below and treeless alpine tundra above. Environmentally dwarfed shrubs commonly forms the upper limit, the decrease in air temperature due to increasing elevation causes the alpine climate. Skin effects and topography can create microclimates that alter the general cooling trend, however, the number of degree days calculated from leaf temperatures may be very similar in the two kinds of timberlines. A series of warm summers in the 1940s seems to have permitted the establishment of “significant numbers” of spruce seedlings above the treeline in the hills near Fairbanks. Survival depends on a sufficiency of new growth to support the tree, the windiness of high-elevation sites is also a potent determinant of the distribution of tree growth. However, snow accumulation in sheltered gullies in the Selkirk Mountains of southeastern British Columbia causes timberline to be 400 metres lower than on exposed intervening shoulders. In a desert, the line marks the driest places where trees can grow. These tend to be called the tree line and occur below about 5,000 ft elevation in the Desert Southwestern United States. In some mountainous areas, higher elevations above the line or on equator-facing and leeward slopes can result in low rainfall. This dries out the soil, resulting in an arid environment unsuitable for trees
6.
Alpine tundra
–
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high altitude. The high altitude causes an adverse climate, which is too cold, Alpine tundra transitions to sub-alpine forests below the tree line, stunted forests occurring at the forest-tundra ecotone are known as Krummholz. With increasing elevation it ends at the line where snow. Alpine tundra occurs in mountains worldwide, the flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the tundra is caused by the lack of greenhouse effect at high altitude. Alpine tundra occurs at high altitude at any latitude. Portions of Montane grasslands and shrublands ecoregions worldwide include alpine tundra, Alpine tundra occupies high-mountain summits, slopes, and ridges above timberline. Aspect plays a role as well, the treeline often occurs at higher elevations on warmer equator-facing slopes, with limited access to infrastructure, only a handful of human communities exist in alpine zones. Many are small and have heavily specialized economies, often relying on such as agriculture, mining. An example of such a town is La Rinconada, Peru, a gold-mining town. A counterexample is El Alto, Bolivia, at 4,150 metres, which has a diverse service and manufacturing economy. Alpine climate is the weather for the alpine tundra. The climate becomes colder at high elevations—this characteristic is described by the rate of air, air tends to get colder as it rises. The dry adiabatic lapse rate is 10 °C per km of elevation or altitude, therefore, moving up 100 metres on a mountain is roughly equivalent to moving 80 kilometers towards the pole. This relationship is only approximate, however, since local factors such as proximity to oceans can drastically modify the climate, typical high-elevation growing seasons range from 45 to 90 days, with average summer temperatures near 10 °C. Growing season temperatures frequently fall below freezing, and frost occurs throughout the season in many areas. Precipitation occurs mainly as snow, but soil water availability is highly variable with season, location. For example, snowfields commonly accumulate on the lee sides of ridges while ridgelines may remain nearly snow free due to redistribution by wind, some alpine habitats may be up to 70% snow free in winter
7.
Taiga
–
Taiga also known as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces and larches. The taiga is the worlds largest biome apart from the oceans, in North America it covers most of inland Canada and Alaska as well as parts of the extreme northern continental United States, where it is known as the Northwoods or North woods. However, the tree species, the length of the growing season. Hoffman discusses the origin of this use in North America. Although at high elevations taiga grades into alpine tundra through Krummholz, it is not an alpine biome only like subalpine forest, Taiga is the worlds largest land biome, and makes up 29% of the worlds forest cover, the largest areas are located in Russia and Canada. The taiga is the terrestrial biome with the lowest annual average temperatures after the tundra, extreme winter minimums in the northern taiga are typically lower than those of the tundra. The lowest reliably recorded temperatures in the Northern Hemisphere were recorded in the taiga of northeastern Russia, the taiga or boreal forest has a subarctic climate with very large temperature range between seasons, but the long and cold winter is the dominant feature. This climate is classified as Dfc, Dwc, Dsc, Dfd and Dwd in the Köppen climate classification scheme, meaning that the summer lasts 1–3 months. In Siberian taiga the average temperature of the coldest month is between −6 °C and −50 °C, the mean annual temperature generally varies from -5 °C to 5 °C, but there are taiga areas in eastern Siberia and interior Alaska-Yukon where the mean annual reaches down to -10 °C. According to some sources, the boreal forest grades into a mixed forest when mean annual temperature reaches about 3 °C. The winters, with temperatures below freezing, last five to seven months. Temperatures vary from −54 °C to 30 °C throughout the whole year, the summers, while short, are generally warm and humid. In much of the taiga, -20 °C would be a winter day temperature and 18 °C an average summer day. In Canada, Scandinavia and Finland, the season is often estimated by using the period of the year when the 24-hour average temperature is +5 °C or more. For the Taiga Plains in Canada, growing season varies from 80 to 150 days, some sources claim 130 days growing season as typical for the taiga. Other sources mention that 50–100 frost-free days are characteristic, data for locations in southwest Yukon gives 80–120 frost-free days. The closed canopy boreal forest in Kenozersky National Park near Plesetsk, Arkhangelsk Province, Russia, the longest growing season is found in the smaller areas with oceanic influences, in coastal areas of Scandinavia and Finland, the growing season of the closed boreal forest can be 145–180 days. High latitudes mean that the sun not rise far above the horizon

Sami people
–
The Sami people are an indigenous Finno-Ugric people inhabiting the Arctic area of Sápmi, which today encompasses parts of far northern Norway, Sweden, Finland, and the Kola Peninsula of Russia. The Sami are the indigenous people of Scandinavia recognized and protected under the international conventions of indigenous peoples. Sami ancestral lands are not well-defined and their traditional languages are the Sami languages and are classified as a branch of the Uralic language family. Traditionally, the Sami have pursued a variety of livelihoods, including fishing, fur trapping. Their best-known means of livelihood is semi-nomadic reindeer herding, currently about 10% of the Sami are connected to reindeer herding, providing them with meat, fur, and transportation. 2,800 Sami people are involved in herding on a full-time basis. For traditional, environmental, cultural, and political reasons, reindeer herding is legally reserved only for Sami people in regions of the Nordic countries. The Sámi are often known in other languages by the exonyms Lap, Lapp, some Sami regard these as pejorative terms, while others do not. Finn was the originally used by Norse speakers to refer to the Sami, as attested in the Icelandic Eddas. As Old Norse gradually developed into the separate Scandinavian languages, Swedes apparently took to using Finn exclusively to refer to inhabitants of Finland, Finnish immigrants to Northern Norway in the 18th and 19th centuries were referred to as Kvens to distinguish them from the Sami Finns. Ethnic Finns are a group from Sami. In fact, Saxo never explicitly connects the Sami with the two Laplands, there is another suggestion that it originally meant wilds. In Finland and Sweden, Lapp is common in names, such as Lappi, Lappeenranta and Lapinlahti in Finland. As already mentioned, Finn is an element in Norwegian place names. In the North Sámi language, láhppon olmmoš means a person who is lost, Sámi refer to themselves as Sámit or Sápmelaš, the word Sámi being inflected into various grammatical forms. It has been proposed that Sámi, Häme, and perhaps Suomi are of the origin and ultimately borrowed from the Baltic word *žēmē. The Baltic word is cognate with Slavic земля, which means land. The Sámi institutions—notably the parliaments, radio and TV stations, theatres, etc. —all use the term Sámi, including when addressing outsiders in Norwegian, Swedish, Finnish, or English

Siberia
–
Siberia is an extensive geographical region, and by the broadest definition is also known as North Asia. Siberia has historically been a part of Russia since the 17th century, the territory of Siberia extends eastwards from the Ural Mountains to the watershed between the Pacific and Arctic drainage basins. It stretches southwards from the Arctic Ocean to the hills of north-central Kazakhstan and to the borders of Mongolia. With an area of 13.1 million square kilometres, Siberia accounts for 77% of Russias land area and this is equivalent to an average population density of about 3 inhabitants per square kilometre, making Siberia one of the most sparsely populated regions on Earth. If it were a country by itself, it would still be the largest country in area, the origin of the name is unknown. Some sources say that Siberia originates from the Siberian Tatar word for sleeping land, another account sees the name as the ancient tribal ethnonym of the Sirtya, a folk, which spoke a language that later evolved into the Ugric languages. This ethnic group was assimilated to the Siberian Tatar people. The modern usage of the name was recorded in the Russian language after the Empires conquest of the Siberian Khanate, a further variant claims that the region was named after the Xibe people. The Polish historian Chycliczkowski has proposed that the name derives from the word for north. He said that the neighbouring Chinese, Arabs and Mongolians would not have known Russian and he suggests that the name is a combination of two words, su and bir. The region is of significance, as it contains bodies of prehistoric animals from the Pleistocene Epoch. Specimens of Goldfuss cave lion cubs, Yuka and another woolly mammoth from Oymyakon, a rhinoceros from the Kolyma River. The Siberian Traps were formed by one of the largest known volcanic events of the last 500 million years of Earths geological history. They continued for a million years and are considered a cause of the Great Dying about 250 million years ago. At least three species of human lived in Southern Siberia around 40,000 years ago, H. sapiens, H. neanderthalensis, the last was determined in 2010, by DNA evidence, to be a new species. Siberia was inhabited by different groups of such as the Enets, the Nenets, the Huns, the Scythians. The Khan of Sibir in the vicinity of modern Tobolsk was known as a prominent figure who endorsed Kubrat as Khagan of Old Great Bulgaria in 630, the Mongols conquered a large part of this area early in the 13th century. With the breakup of the Golden Horde, the autonomous Khanate of Sibir was established in the late 15th century, turkic-speaking Yakut migrated north from the Lake Baikal region under pressure from the Mongol tribes during the 13th to 15th century

Habitat
–
A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term typically refers to the zone in which the organism lives and it is the natural environment in which an organism lives, or the physical environment that surrounds a species population. Every organism has certain habitat needs for the conditions in which it will thrive, habitat types include polar, temperate, subtropical and tropical. The terrestrial vegetation type may be forest, steppe, grassland, the word habitat has been in use since about 1755 and derives from the Latin third-person singular present indicative of habitāre, to inhabit, from habēre, to have or to hold. Habitat can be defined as the environment of an organism. It is similar in meaning to a biotope, an area of environmental conditions associated with a particular community of plants. Generally speaking, animal communities are reliant on specific types of plant communities, some plants and animals are generalists, and their habitat requirements are met in a wide range of locations. The small white butterfly for example is found on all the continents of the world apart from Antarctica and its larvae feed on a wide range of Brassicas and various other plant species, and it thrives in any open location with diverse plant associations. Disturbance is important in the creation of biodiverse habitats, in the absence of disturbance, a climax vegetation cover develops that prevents the establishment of other species. Lightning strikes and toppled trees in tropical forests allow species richness to be maintained as pioneering species move in to fill the gaps created. Similarly coastal habitats can become dominated by kelp until the seabed is disturbed by a storm, another cause of disturbance is when an area may be overwhelmed by an invasive introduced species which is not kept under control by natural enemies in its new habitat. Terrestrial habitat types include forests, grasslands, wetlands and deserts, within these broad biomes are more specific habitats with varying climate types, temperature regimes, soils, altitudes and vegetation types. Many of these habitats grade into each other and each one has its own communities of plants. A habitat may suit a particular species well, but its presence or absence at any particular location depends to some extent on chance, on its dispersal abilities, freshwater habitats include rivers, streams, lakes, ponds, marshes and bogs. Although some organisms are found across most of these habitats, the majority have more specific requirements, similarly, aquatic plants can be floating, semi-submerged, submerged or grow in permanently or temporarily saturated soils besides bodies of water. Marine habitats include brackish water, estuaries, bays, the sea, the intertidal zone. Further variations include rock pools, sand banks, mudflats, brackish lagoons, sandy and pebbly beaches, the benthic zone or seabed provides a home for both static organisms, anchored to the substrate, and for a large range of organisms crawling on or burrowing into the surface. A desert is not the kind of habitat that favours the presence of amphibians, with their requirement for water to keep their skins moist, nevertheless, some frogs live in deserts, creating moist habitats underground and hibernating while conditions are adverse

Conservation movement
–
The early conservation movement included fisheries and wildlife management, water, soil conservation and sustainable forestry. Some say the movement is part of the broader and more far-reaching environmental movement. Chiefly in the United States, conservation is seen as differing from environmentalism in that it aims to preserve natural resources expressly for their sustainable use by humans. The conservation movement can be traced back to John Evelyns work Sylva, published as a book two years later, it was one of the most highly influential texts on forestry ever published. The field developed during the 18th century, especially in Prussia and these methods were first applied rigorously in British India from the early-19th century. This early ecological idea was in order to preserve the growth of teak trees. The first forestry officer was appointed in 1806 to regulate and preserve the trees necessary for shipbuilding and this promising start received a setback in the 1820s and 30s, when laissez-faire economics and complaints from private landowners brought these early conservation attempts to an end. Conservation was revived in the century, with the first practical application of scientific conservation principles to the forests of India. Edward Percy Stebbing warned of desertification of India and this was the first case of state management of forests in the world. These local attempts gradually received more attention by the British government as the unregulated felling of trees continued unabated, in 1850, the British Association in Edinburgh formed a committee to study forest destruction at the behest of Dr. Hugh Cleghorn a pioneer in the nascent conservation movement. He had become interested in forest conservation in Mysore in 1847, in the same year, Cleghorn organised the Madras Forest Department and in 1860 the Department banned the use shifting cultivation. Cleghorns 1861 manual, The forests and gardens of South India, in 1861, the Forest Department extended its remit into the Punjab. Sir Dietrich Brandis, a German forester, joined the British service in 1856 as superintendent of the forests of Pegu division in eastern Burma. During that time Burmas teak forests were controlled by militant Karen tribals and he introduced the taungya system, in which Karen villagers provided labour for clearing, planting and weeding teak plantations. After seven years in Burma, Brandis was appointed Inspector General of Forests in India and he formulated new forest legislation and helped establish research and training institutions. The Imperial Forest School at Dehradun was founded by him, germans were prominent in the forestry administration of British India. As well as Brandis, Berthold Ribbentrop and Sir William P. D, schlich brought new methods to Indian conservation, the latter becoming the Inspector-General in 1883 after Brandis stepped down. Schlich helped to establish the journal Indian Forester in 1874, and he authored the five-volume Manual of Forestry on silviculture, forest management, forest protection, and forest utilisation, which became the standard and enduring textbook for forestry students

Biodiversity action plan
–
A biodiversity action plan is an internationally recognized program addressing threatened species and habitats and is designed to protect and restore biological systems. The original impetus for these plans derives from the 1992 Convention on Biological Diversity, as of 2009,191 countries have ratified the CBD, but only a fraction of these have developed substantive BAP documents. A fundamental method of engagement to a BAP is thorough documentation regarding individual species and it is also useful to compile time trends of population estimates in order to understand the dynamics of population variability and vulnerability. A species plan component of a country’s BAP should ideally entail a thorough description of the range, habitat, behaviour, breeding, once a determination has been made of conservation status, a plan can then be created to conserve and restore the species population to target levels. The plan should also articulate which public and private agencies should implement the protection strategy, where a number of threatened species depend upon a specific habitat, it may be appropriate to prepare a habitat protection element of the Biodiversity Action Plan. Examples of such habitats are, raised acidic bogs of Scotland, Waterberg Biosphere bushveld in South Africa, California’s coastal wetlands. In this case also, careful inventories of species and also the geographic extent, then, as with species plans, a program can be created to protect, enhance and/or restore habitat using similar strategies as discussed above under the species plans. Some examples of countries which have produced substantive Biodiversity Action Plans follow. Preparation of a country BAP may cost up to 100 million pounds sterling, if plans took into account neglected groups, the cost would be higher. Obviously costs for countries with small geographical area or simplified ecosystems have a lesser cost. For example, the St. Lucia BAP has been costed in the area of several million pounds sterling, australia has developed a detailed and rigorous Biodiversity Action Plan. This document estimates that the number of indigenous species may be 560,000. There is, however, serious ongoing concerns, particularly in regards to the negative impact on water quality from land use practices. Also, climate change impact is feared to be significant, considerable analysis has been conducted on the sustainable yield of firewood production, a major threat to deforestation in most tropical countries. Biological inventory work, assessment of harvesting practices, and computer modeling of the dynamics of treefall, rot, New Zealand has ratified the Convention on Biological Diversity and as part of The New Zealand Biodiversity Strategy and Biodiversity Action Plans are implemented on ten separate themes. Local government and some also have their own Biodiversity Action Plan. The St. Lucia BAP recognizes impacts of large numbers of tourists to the marine, the BAP specifically acknowledges that the carrying capacity for human use and water pollution discharge of sensitive reef areas was exceeded by the year 1990. The plan also addresses conservation of the historic island fishing industry, in 1992, several institutions in conjunction with native fishermen to produce a sustainable management plan for fishery resources, embodied in the Soufrière Marine Management Area
