87-470: The development of such plans at a local level is guided by the publication of a biodiversity action plan at national i.e. UK level and executed locally by 'biodiversity partnerships' which include key stakeholders from different sectors. Progress on local plans is overseen by different agencies in each of the four administrations. As at January 2012, there were many dozens of LBAPs in England overseen by

174-651: A biodiversity friendly production. It has not been common for companies to integrate biodiversity aspects into their value chain , but some companies and organizations have shown overall efforts for implementing better practices. An existing example for guidelines on biodiversity practices in agriculture is the Biodiversity Action Plan for spice production in India . By planning and implementing biodiversity friendly measures, farmers can mitigate negative impacts and support positive influences. Where

261-478: A country BAP may cost up to 100 million pounds sterling, with annual maintenance costs roughly ten percent of the initial cost. 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 much lesser cost. For example, the St. Lucia BAP has been costed in the area of several million pounds sterling. Australia has developed

348-501: A country, endangered species are initially supported on a national level then internationally. Ecotourism may be utilized to support the economy and encourages tourists to continue to visit and support species and ecosystems they visit, while they enjoy the available amenities provided. International biodiversity impacts global livelihood, food systems, and health. Problematic pollution, over consumption, and climate change can devastate international biodiversity. Nature-based solutions are

435-517: A critical tool for a global resolution. Many species are in danger of becoming extinct and need world leaders to be proactive with the Kunming-Montreal Global Biodiversity Framework . Terrestrial biodiversity is thought to be up to 25 times greater than ocean biodiversity. Forests harbour most of Earth's terrestrial biodiversity. The conservation of the world's biodiversity is thus utterly dependent on

522-576: A detailed and rigorous Biodiversity Action Plan. This document estimates that the total number of indigenous species may be 560,000, many of which are endemic. A key element of the BAP is protection of the Great Barrier Reef , which is actually in a much higher state of health than most of the world’s reefs , Australia having one of the highest percentages of treated wastewater . There are however serious ongoing concerns, particularly in regards to

609-459: A fact which makes it difficult for many smaller countries and poorer countries to comply. In terms of the plans themselves, many countries have adopted pro-forma plans including little research and even less in the way of natural resource management. Almost universally, this has resulted in plans which emphasize plants and vertebrate animals, and which overlook fungi, invertebrate animals and micro-organisms. With regard to specific world regions, there

696-455: A first-order positive feedback (more ancestors, more descendants) and/or a negative feedback arising from resource limitation. Hyperbolic model implies a second-order positive feedback. Differences in the strength of the second-order feedback due to different intensities of interspecific competition might explain the faster rediversification of ammonoids in comparison to bivalves after the end-Permian extinction . The hyperbolic pattern of

783-460: A limit would also cap the number of species. While records of life in the sea show a logistic pattern of growth, life on land (insects, plants and tetrapods) shows an exponential rise in diversity. As one author states, "Tetrapods have not yet invaded 64 percent of potentially habitable modes and it could be that without human influence the ecological and taxonomic diversity of tetrapods would continue to increase exponentially until most or all of

870-486: 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 special habitats are: raised acidic bogs of Scotland; Waterberg Biosphere bushveld in South Africa; California’s coastal wetlands ; and Sweden’s Stora Alvaret on the island of Öland . In this case also, careful inventories of species and also

957-430: A patch to existing problems. Increasingly, biodiversity planners are looking through the lens of ecosystem services . Critics of biodiversity are often confusing the need to protect species (their intrinsic value) with the need to maintain ecosystem processes, which ultimately maintain human society and do not compromise economic development. Hence, a core principle of biodiversity management, that traditional BAPs overlook,

1044-407: A plan can then be created to conserve and restore the species population to target levels. Examples of programmatic protection elements are: habitat restoration ; protection of habitat from urban development ; establishment of property ownership; limitations on grazing or other agricultural encroachment into habitat; reduction of slash-and-burn agricultural practises; outlawing killing or collecting

1131-566: A rapid growth in biodiversity via the Cambrian explosion . In this period, the majority of multicellular phyla first appeared. The next 400 million years included repeated, massive biodiversity losses. Those events have been classified as mass extinction events. In the Carboniferous , rainforest collapse may have led to a great loss of plant and animal life. The Permian–Triassic extinction event , 251 million years ago,

1218-437: A significant reduction of the current rate of biodiversity loss at the global, regional and national level as a contribution to poverty alleviation and to the benefit of life on Earth”. To achieve this outcome, biodiversity management will depend on maintaining structure and function. Biodiversity is not singularly definable but may be understood via a series of management principles under BAPs, such as: 1. that biodiversity

1305-590: A third of the Earth's land mass) and are home to approximately 80% of the world's biodiversity. About 1 billion hectares are covered by primary forests. Over 700 million hectares of the world's woods are officially protected. The biodiversity of forests varies considerably according to factors such as forest type, geography, climate and soils – in addition to human use. Most forest habitats in temperate regions support relatively few animal and plant species and species that tend to have large geographical distributions, while

1392-587: Is a notable lack of substantive participation by most of the Middle Eastern countries and much of Africa, the latter of which may be impeded by economic considerations of plan preparation. Some governments such as the European Union have diverted the purpose of a biodiversity action plan, and implemented the convention accord by a set of economic development policies with referencing certain ecosystems' protection. The definition of biodiversity under

1479-405: Is an increase in biodiversity from the poles to the tropics . Thus localities at lower latitudes have more species than localities at higher latitudes . This is often referred to as the latitudinal gradient in species diversity. Several ecological factors may contribute to the gradient, but the ultimate factor behind many of them is the greater mean temperature at the equator compared to that at

1566-418: Is conserved across all levels and scales – structure, function and composition are conserved at site, regional, state and national scales. 2. that examples of all ecological communities are adequately managed for conservation. 3. ecological communities are managed to support and enhance viable populations of animals, fungi, micro-organisms and plants and ecological functions. Biodiversity and wildlife are not

1653-475: Is decreasing today. Climate change also plays a role. This can be seen for example in the effects of climate change on biomes . This anthropogenic extinction may have started toward the end of the Pleistocene , as some studies suggest that the megafaunal extinction event that took place around the end of the last ice age partly resulted from overhunting. Biologists most often define biodiversity as

1740-491: Is estimated at 5.0 x 10 and weighs 50 billion tonnes . In comparison, the total mass of the biosphere has been estimated to be as much as four trillion tons of carbon . In July 2016, scientists reported identifying a set of 355 genes from the last universal common ancestor (LUCA) of all organisms living on Earth. The age of Earth is about 4.54 billion years. The earliest undisputed evidence of life dates at least from 3.7 billion years ago, during

1827-630: Is extremely large. Five major divisions of habitat have been identified in Uzbekistan ’s BAP: Wetlands (including reed habitat and man-made marsh ); desert ecosystems (including sandy, stony and clay); steppes ; riparian ecosystems; and mountain ecosystems. Over 27,000 species have been inventoried in the country, with a high rate of endemism for fishes and reptiles. Principal threats to biodiversity are related to human activities associated with overpopulation and generally related to agricultural intensification. Major geographic regions encompassed by

1914-552: Is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator . Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since life began on Earth , six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked

2001-427: Is local biodiversity, which directly impacts daily life, affecting the availability of fresh water, food choices, and fuel sources for humans. Regional biodiversity includes habitats and ecosystems that synergizes and either overlaps or differs on a regional scale. National biodiversity within a country determines the ability for a country to thrive according to its habitats and ecosystems on a national scale. Also, within

2088-449: Is noteworthy because of its extensive detail, clarity of endangerment mechanisms, specificity of actions, follow up monitoring program and its inclusion of migrating cetaceans and pelagic birds. On August 28, 2007, the new Biodiversity Action Plan (BAP) [launched in 1997] identified 1,149 species and 65 habitats in the UK that needed conservation and greater protection. The updated list included

2175-420: Is often available in published literature; however, for fungi, invertebrate animals, micro-organisms and many plants, such information may require considerable local data collection. It is also useful to compile time trends of population estimates in order to understand the dynamics of population variability and vulnerability. In some parts of the world complete species inventories are not realistic; for example, in

2262-401: Is possible to build fractal hyper volumes, whose fractal dimension rises to three moving towards the equator . A biodiversity hotspot is a region with a high level of endemic species that have experienced great habitat loss . The term hotspot was introduced in 1988 by Norman Myers . While hotspots are spread all over the world, the majority are forest areas and most are located in

2349-561: Is so full, that that district produces the most variety which is the most examined." Biodiversity is the result of 3.5 billion years of evolution . The origin of life has not been established by science, however, some evidence suggests that life may already have been well-established only a few hundred million years after the formation of the Earth . Until approximately 2.5 billion years ago, all life consisted of microorganisms – archaea , bacteria , and single-celled protozoans and protists . Biodiversity grew fast during

2436-451: Is the need to incorporate cultural, social and economic values in the process. Modern day BAPs use an analysis of ecosystem services , key ecological process drivers, and use species as one of many indicators of change. They would seek to maintain structure and function by addressing habitat connectivity and resilience and may look at communities of species (threatened or otherwise) as one method of monitoring outcomes. Ultimately, species are

2523-405: Is uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of recent geologic sections. Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity 300 million years ago, whereas others consider the fossil record reasonably reflective of the diversification of life. Estimates of

2610-515: The Business Biodiversity Offsets Program are now integral to any plans to manage biodiversity, including the development of BAPs. Biodiversity Biodiversity is the variability of life on Earth . It can be measured on various levels. There is for example genetic variability , species diversity , ecosystem diversity and phylogenetic diversity. Diversity is not distributed evenly on Earth . It

2697-792: The Eoarchean era after a geological crust started to solidify following the earlier molten Hadean eon. There are microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia . Other early physical evidence of a biogenic substance is graphite in 3.7 billion-year-old meta-sedimentary rocks discovered in Western Greenland .. More recently, in 2015, "remains of biotic life " were found in 4.1 billion-year-old rocks in Western Australia . According to one of

2784-499: The Madagascar dry deciduous forests , many species are completely undocumented and much of the region has never even been systematically explored by scientists. A species plan component of a country’s BAP should ideally entail a thorough description of the range, habitat, behaviour, breeding and interaction with other species. Once a determination has been made of conservation status (e.g. rare , endangered, threatened, vulnerable),

2871-713: The Phanerozoic (the last 540 million years), especially during the so-called Cambrian explosion —a period during which nearly every phylum of multicellular organisms first appeared. However, recent studies suggest that this diversification had started earlier, at least in the Ediacaran , and that it continued in the Ordovician . Over the next 400 million years or so, invertebrate diversity showed little overall trend and vertebrate diversity shows an overall exponential trend. This dramatic rise in diversity

2958-461: The Stone Age , species loss has accelerated above the average basal rate, driven by human activity. Estimates of species losses are at a rate 100–10,000 times as fast as is typical in the fossil record. Loss of biodiversity results in the loss of natural capital that supplies ecosystem goods and services . Species today are being wiped out at a rate 100 to 1,000 times higher than baseline, and

3045-685: The hedgehog , house sparrow , grass snake and the garden tiger moth , while otters , bottlenose dolphins and red squirrels remained in need of habitat protection. In May 2011, the European Commission adopted a new strategy to halt the loss of biodiversity and ecosystem services in the EU by 2020, in line with the commitments made at the 10th meeting of the Convention on Biological Diversity (CBD) held in Nagoya, Japan in 2010. In 2012

3132-504: The tropics . Brazil 's Atlantic Forest is considered one such hotspot, containing roughly 20,000 plant species, 1,350 vertebrates and millions of insects, about half of which occur nowhere else. The island of Madagascar and India are also particularly notable. Colombia is characterized by high biodiversity, with the highest rate of species by area unit worldwide and it has the largest number of endemics (species that are not found naturally anywhere else) of any country. About 10% of

3219-417: The world population growth arises from a second-order positive feedback between the population size and the rate of technological growth. The hyperbolic character of biodiversity growth can be similarly accounted for by a feedback between diversity and community structure complexity. The similarity between the curves of biodiversity and human population probably comes from the fact that both are derived from

3306-752: The "totality of genes , species and ecosystems of a region". An advantage of this definition is that it presents a unified view of the traditional types of biological variety previously identified: Biodiversity is most commonly used to replace the more clearly-defined and long-established terms, species diversity and species richness . However, there is no concrete definition for biodiversity, as its definition continues to be defined. Other definitions include (in chronological order): According to estimates by Mora et al. (2011), there are approximately 8.7 million terrestrial species and 2.2 million oceanic species. The authors note that these estimates are strongest for eukaryotic organisms and likely represent

3393-593: The 1992 Convention on Biological Diversity (CBD). As of 2009, 191 countries have ratified the CBD, but only a fraction of these have developed substantive BAP documents. The principal elements of a BAP typically include: (a) preparing inventories of biological information for selected species or habitats; (b) assessing the conservation status of species within specified ecosystems ; (c) creation of targets for conservation and restoration ; and (d) establishing budgets, timelines and institutional partnerships for implementing

3480-773: The BAP include the Aral Sea Programme (threatened by long-term drainage and salination , largely for cotton production), the Nuratau Biosphere Reserve , and the Western Tien Shan Mountains Programme (in conjunction with Kazakhstan and Kyrgyzstan ). Some developing countries criticize the emphasis of BAPs, because these plans inherently favour consideration of wildlife protection above food and industrial production, and in some cases may represent an obstacle to population growth. The plans are costly to produce,

3567-491: The BAP. A fundamental method of engagement to a BAP is thorough documentation regarding individual species, with emphasis upon the population distribution and conservation status . This task, while fundamental, is highly daunting, since only an estimated ten percent of the world’s species are believed to have been characterized as of 2006, most of these unknowns being fungi , invertebrate animals, micro-organisms and plants. For many bird, mammal and reptile species, information

3654-488: The Convention on Biological Diversity now recognises that biodiversity is a combination of ecosystem structure and function, as much as its components e.g. species, habitats and genetic resources . Article 2 states: in addressing the boundless complexity of biological diversity, it has become conventional to think in hierarchical terms, from the genetic material within individual cells, building up through individual organisms, populations, species and communities of species, to

3741-606: The IUCN's critically endangered . Numerous scientists and the IPBES Global Assessment Report on Biodiversity and Ecosystem Services assert that human population growth and overconsumption are the primary factors in this decline. However, other scientists have criticized this finding and say that loss of habitat caused by "the growth of commodities for export" is the main driver. Some studies have however pointed out that habitat destruction for

3828-726: The JNCC website. Content from the original UK BAP website has been archived by the National Archives as snapshots from various dates (for example, UK BAP : copy March 2011; copy 2012 ). Twenty-six years prior to the international biodiversity convention, the United States had launched a national program to protect threatened species in the form of the 1966 Endangered Species Act . The legislation created broad authority for analyzing and listing species of concern, and mandated that Species Recovery Plans be created. Thus, while

3915-872: The Soufrière Marine Management Area. The St. Lucia BAP features significant involvement from the University of the West Indies . Specific detailed attention is given to three species of threatened marine turtles, to a variety of vulnerable birds and a number of pelagic fishes and cetaceans . In terms of habitat conservation the plan focusses attention on the biologically productive mangrove swamps and notes that virtually all mangrove areas had already come under national protection by 1984. The Tanzania national BAP addresses issues related to sustainable use of Lake Manyara , an extensive freshwater lake, whose usage by humans accelerated in

4002-468: The UK BAP was succeeded by the 'UK Post-2010 Biodiversity Framework'. To support the work of the UK BAP, the UK BAP website was created by JNCC in 2001. The website contained information on the BAP process, hosted all relevant documents, and provided news and relevant updates. In March 2011, as part of the UK government’s review of websites, the UK BAP site was ‘closed’, and the core content was migrated into

4089-476: The USA is an unratified signer of the accord, arguably it has the longest track record and most comprehensive program of species protection of any country. There are about 7000 listed species (e.g. endangered or threatened), of which about half have approved Recovery Plans. While this number of species seems high compared to other countries, the value is rather indicative of the total number of species characterized, which

4176-461: The available eco-space is filled." It also appears that the diversity continues to increase over time, especially after mass extinctions. On the other hand, changes through the Phanerozoic correlate much better with the hyperbolic model (widely used in population biology , demography and macrosociology , as well as fossil biodiversity) than with exponential and logistic models. The latter models imply that changes in diversity are guided by

4263-443: The biosphere overall...At the same time, in seeking to make management intervention as efficient as possible, it is essential to take an holistic view of biodiversity and address the interactions that species have with each other and their non-living environment, i.e. to work from an ecological perspective. The World Summit on Sustainable Development endorsed the objectives of the Convention on Biological Diversity to “achieve by 2010

4350-540: The current sixth mass extinction match or exceed rates of loss in the five previous mass extinction events in the fossil record . Biodiversity loss is in fact "one of the most critical manifestations of the Anthropocene " (since around the 1950s); the continued decline of biodiversity constitutes "an unprecedented threat" to the continued existence of human civilization. The reduction is caused primarily by human impacts , particularly habitat destruction . Since

A 2017 study published in PLOS One found that the biomass of insect life in Germany had declined by three-quarters in the last 25 years. Dave Goulson of Sussex University stated that their study suggested that humans "appear to be making vast tracts of land inhospitable to most forms of life, and are currently on course for ecological Armageddon. If we lose

However, many other taxa were affected by this crisis, which affected even marine taxa, such as ammonites , which also became extinct around that time. The biodiversity of the past is called Paleobiodiversity. The fossil record suggests that the last few million years featured the greatest biodiversity in history . However, not all scientists support this view, since there

4611-451: The estimated global value of ecosystem services (not captured in traditional markets) at an average of $ 33 trillion annually. With regards to provisioning services, greater species diversity has the following benefits: With regards to regulating services, greater species diversity has the following benefits: Greater species diversity Agricultural diversity can be divided into two categories: intraspecific diversity , which includes

4698-428: The expansion of agriculture and the overexploitation of wildlife are the more significant drivers of contemporary biodiversity loss, not climate change . Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions and seasons. Among other factors, the diversity of all living things ( biota ) depends on temperature , precipitation , altitude , soils , geography and

4785-491: The genetic variation within a single species, like the potato ( Solanum tuberosum ) that is composed of many different forms and types (e.g. in the U.S. they might compare russet potatoes with new potatoes or purple potatoes, all different, but all part of the same species, S. tuberosum ). The other category of agricultural diversity is called interspecific diversity and refers to the number and types of different species. Agricultural diversity can also be divided by whether it

4872-581: The geographic extent and quality of the habitat must be documented. 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 individual countries which have produced substantive Biodiversity Action Plans follow. In every example the plans concentrate on plants and vertebrate animals, with very little attention to neglected groups such as fungi, invertebrate animals and micro-organisms, even though these are also part of biodiversity. Preparation of

4959-587: The insects then everything is going to collapse." In 2020 the World Wildlife Foundation published a report saying that "biodiversity is being destroyed at a rate unprecedented in human history". The report claims that 68% of the population of the examined species were destroyed in the years 1970 – 2016. Of 70,000 monitored species, around 48% are experiencing population declines from human activity (in 2023), whereas only 3% have increasing populations. Rates of decline in biodiversity in

5046-596: The interactions between other species. The study of the spatial distribution of organisms , species and ecosystems , is the science of biogeography . Diversity consistently measures higher in the tropics and in other localized regions such as the Cape Floristic Region and lower in polar regions generally. Rain forests that have had wet climates for a long time, such as Yasuní National Park in Ecuador , have particularly high biodiversity. There

5133-737: The interference of the hyperbolic trend with cyclical and stochastic dynamics. Most biologists agree however that the period since human emergence is part of a new mass extinction, named the Holocene extinction event , caused primarily by the impact humans are having on the environment. It has been argued that the present rate of extinction is sufficient to eliminate most species on the planet Earth within 100 years. New species are regularly discovered (on average between 5–10,000 new species each year, most of them insects ) and many, though discovered, are not yet classified (estimates are that nearly 90% of all arthropods are not yet classified). Most of

5220-480: The litmus test for biodiversity – viable populations of species can only be expected to exist in relatively intact habitats. However, the rationale behind BAPs is to "conserve and restore" biodiversity. One of the fastest developing areas of management is biodiversity offsets. The principles are in keeping with ecological impact assessment, which in turn depends on good quality BAPs for evaluation. Contemporary principles of biodiversity management, such as those produced by

5307-430: The lower bound of prokaryote diversity. Other estimates include: Since the rate of extinction has increased, many extant species may become extinct before they are described. Not surprisingly, in the animalia the most studied groups are birds and mammals , whereas fishes and arthropods are the least studied animals groups. During the last century, decreases in biodiversity have been increasingly observed. It

5394-513: The marine and coastal diversity of the Soufrière area of the country. 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

5481-829: The montane forests of Africa, South America and Southeast Asia and lowland forests of Australia, coastal Brazil, the Caribbean islands, Central America and insular Southeast Asia have many species with small geographical distributions. Areas with dense human populations and intense agricultural land use, such as Europe , parts of Bangladesh, China, India and North America, are less intact in terms of their biodiversity. Northern Africa, southern Australia, coastal Brazil, Madagascar and South Africa, are also identified as areas with striking losses in biodiversity intactness. European forests in EU and non-EU nations comprise more than 30% of Europe's land mass (around 227 million hectares), representing an almost 10% growth since 1990. Generally, there

5568-522: The ongoing 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 and harvest; have been carried out to adduce data on safe harvesting rates. Extensive research has also been conducted on

The designation of the Lake Manyara Biosphere Reserve under UNESCO 's Man and the Biosphere Programme in 1981 combines conservation of the lake and surrounding high value forests with sustainable use of the wetlands area and simple agriculture. This BAP has united principal lake users in establishing management targets. The biosphere reserve has induced sustainable management of

5742-468: The planet's species went extinct prior to the evolution of humans. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86% have not yet been described. However, a May 2016 scientific report estimates that 1 trillion species are currently on Earth, with only one-thousandth of one percent described. The total amount of related DNA base pairs on Earth

5829-546: The poles. Even though terrestrial biodiversity declines from the equator to the poles, some studies claim that this characteristic is unverified in aquatic ecosystems , especially in marine ecosystems . The latitudinal distribution of parasites does not appear to follow this rule. Also, in terrestrial ecosystems the soil bacterial diversity has been shown to be highest in temperate climatic zones, and has been attributed to carbon inputs and habitat connectivity. In 2016, an alternative hypothesis ("the fractal biodiversity")

Diversity appears to increase continually in the absence of natural selection. The existence of a global carrying capacity , limiting the amount of life that can live at once, is debated, as is the question of whether such

6003-584: The rate of extinctions is increasing. This process destroys the resilience and adaptability of life on Earth. In 2006, many species were formally classified as rare or endangered or threatened ; moreover, scientists have estimated that millions more species are at risk which have not been formally recognized. About 40 percent of the 40,177 species assessed using the IUCN Red List criteria are now listed as threatened with extinction —a total of 16,119. As of late 2022 9251 species were considered part of

6090-583: The relation of brush clearance to biodiversity decline and impact on water tables ; for example, these effects have been analyzed in the Toolibin Lake wetlands region. 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 companies also have their own Biodiversity Action Plan. The St. Lucia BAP recognizes impacts of large numbers of tourists to

6177-913: The researchers, "If life arose relatively quickly on Earth...then it could be common in the universe ." There have been many claims about biodiversity's effect on the ecosystem services , especially provisioning and regulating services . Some of those claims have been validated, some are incorrect and some lack enough evidence to draw definitive conclusions. Ecosystem services have been grouped in three types: Experiments with controlled environments have shown that humans cannot easily build ecosystems to support human needs; for example insect pollination cannot be mimicked, though there have been attempts to create artificial pollinators using unmanned aerial vehicles . The economic activity of pollination alone represented between $ 2.1–14.6 billion in 2003. Other sources have reported somewhat conflicting results and in 1997 Robert Costanza and his colleagues reported

6264-477: The same thing. The traditional focus on threatened species in BAPs is at odds with the principles of biodiversity management because, by the time species become threatened, the processes that maintain biodiversity are already compromised. Individual species are also regarded as generally poor indicators of biodiversity when it comes to actual planning. A species approach to BAPs only serves to identify and at best, apply

6351-693: The species of the Earth can be found in Colombia, including over 1,900 species of bird, more than in Europe and North America combined, Colombia has 10% of the world's mammals species, 14% of the amphibian species and 18% of the bird species of the world. Madagascar dry deciduous forests and lowland rainforests possess a high ratio of endemism . Since the island separated from mainland Africa 66 million years ago, many species and ecosystems have evolved independently.

As at January 2012 there were 25 LBAPs in place covering each of Scotland's local authority areas and both the Cairngorms and Loch Lomond and The Trossachs national parks. By January 2012 there were LBAPs published or in draft form for each of 24 areas identified across Wales including

6612-419: The terrestrial diversity is found in tropical forests and in general, the land has more species than the ocean; some 8.7 million species may exist on Earth, of which some 2.1 million live in the ocean. It is estimated that 5 to 50 billion species have existed on the planet. Assuming that there may be a maximum of about 50 million species currently alive, it stands to reason that greater than 99% of

6699-451: The three national parks. The Wales Biodiversity Partnership brings together most of the main players across Wales to assist in the process of assembling and delivering LBAPs. Biodiversity action plan A biodiversity action plan ( BAP ) 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

6786-479: The upcoming years. As of 2012, some studies suggest that 25% of all mammal species could be extinct in 20 years. In absolute terms, the planet has lost 58% of its biodiversity since 1970 according to a 2016 study by the World Wildlife Fund. The Living Planet Report 2014 claims that "the number of mammals, birds, reptiles, amphibians, and fish across the globe is, on average, about half the size it

6873-773: The way in which we interact with and use the world's forests. A new method used in 2011, put the total number of species on Earth at 8.7 million, of which 2.1 million were estimated to live in the ocean. However, this estimate seems to under-represent the diversity of microorganisms. Forests provide habitats for 80 percent of amphibian species , 75 percent of bird species and 68 percent of mammal species. About 60 percent of all vascular plants are found in tropical forests. Mangroves provide breeding grounds and nurseries for numerous species of fish and shellfish and help trap sediments that might otherwise adversely affect seagrass beds and coral reefs, which are habitats for many more marine species. Forests span around 4 billion acres (nearly

6960-482: The wetlands, including monitoring groundwater and the chemistry of the escarpment water source. The United Kingdom Biodiversity Action Plan covers not only terrestrial species associated with lands within the UK, but also marine species and migratory birds, which spend a limited time in the UK or its offshore waters. The UK plan encompasses "391 Species Action Plans, 45 Habitat Action Plans and 162 Local Biodiversity Action Plans with targeted actions". This plan

7047-630: The world's flowering plants , 12% of mammals and 17% of reptiles , amphibians and birds —along with nearly 240 million people. Many regions of high biodiversity and/or endemism arise from specialized habitats which require unusual adaptations, for example, alpine environments in high mountains , or Northern European peat bogs . Accurately measuring differences in biodiversity can be difficult. Selection bias amongst researchers may contribute to biased empirical research for modern estimates of biodiversity. In 1768, Rev. Gilbert White succinctly observed of his Selborne, Hampshire "all nature

7134-482: Was 40 years ago". Of that number, 39% accounts for the terrestrial wildlife gone, 39% for the marine wildlife gone and 76% for the freshwater wildlife gone. Biodiversity took the biggest hit in Latin America , plummeting 83 percent. High-income countries showed a 10% increase in biodiversity, which was canceled out by a loss in low-income countries. This is despite the fact that high-income countries use five times

7221-553: Was estimated in 2007 that up to 30% of all species will be extinct by 2050. Of these, about one eighth of known plant species are threatened with extinction . Estimates reach as high as 140,000 species per year (based on Species-area theory ). This figure indicates unsustainable ecological practices, because few species emerge each year. The rate of species loss is greater now than at any time in human history, with extinctions occurring at rates hundreds of times higher than background extinction rates. and expected to still grow in

7308-483: Was marked by periodic, massive losses of diversity classified as mass extinction events. A significant loss occurred in anamniotic limbed vertebrates when rainforests collapsed in the Carboniferous , but amniotes seem to have been little affected by this event; their diversification slowed down later, around the Asselian / Sakmarian boundary, in the early Cisuralian (Early Permian ), about 293 Ma ago. The worst

7395-401: Was proposed to explain the biodiversity latitudinal gradient. In this study, the species pool size and the fractal nature of ecosystems were combined to clarify some general patterns of this gradient. This hypothesis considers temperature , moisture , and net primary production (NPP) as the main variables of an ecosystem niche and as the axis of the ecological hypervolume . In this way, it

7482-567: Was the Permian-Triassic extinction event , 251 million years ago. Vertebrates took 30 million years to recover from this event. The most recent major mass extinction event, the Cretaceous–Paleogene extinction event , occurred 66 million years ago. This period has attracted more attention than others because it resulted in the extinction of the non-avian dinosaurs , which were represented by many lineages at

7569-425: Was the worst; vertebrate recovery took 30 million years. Human activities have led to an ongoing biodiversity loss and an accompanying loss of genetic diversity . This process is often referred to as Holocene extinction , or sixth mass extinction . For example, it was estimated in 2007 that up to 30% of all species will be extinct by 2050. Destroying habitats for farming is a key reason why biodiversity
