The AZE has identified sites worldwide exhibiting at least one criterion for protection Table 2 , and these sites are home to hundreds of amphibian species listed by IUCN as between Vulnerable and Critically Endangered. Throughout the current amphibian extinction crisis, increasing public awareness has been a critical component of conservation efforts. Table 1. The IUCN has defined six protected area management categories, based on primary management objective Table 1. Primary management objectives for the six protected area management categories as defined by the IUCN. Appendix Level of Protection Trade Appendix I Species threatened with extinction Permitted only in exceptional circumstances Appendix II Species might be threatened with extinction but not required Trade is controlled to ensure survival Appendix III Species are protected in at least one country Trade is controlled after a member country has indicated that assistance is needed in this capacity Table 3. Total spp. Despite increases in the size and number of protected areas, however, the overall area constitutes a small percentage of the earth's surface. These categories range from 'Extinct' to 'Least Concern' Figure 1. The evaluation of these criteria includes analyses regarding the number of mature individuals, generation time, and population fragmentation. Three criteria must be met in order to prioritize a site for protection Table 2. Berger, L. Table 2. These species' native habitats are afforded protection at various levels of organization. In a worldwide effort to bring amphibian population declines to the forefront, the Amphibian Ark declared as the "Year of the Frog," a time in which conservationists showcased amphibian diversity in zoos and aquaria while detailing their current plight. On the ecological roles of salamanders. In addition, IUCN's Amphibian Specialist Group ASG has partnered with governmental and non-governmental organizations and individuals to create new protected areas and minimize further population declines due to habitat fragmentation and loss. Figure excludes protected areas with unknown year of establishment. Conservation education often begins in elementary school and may be enhanced through summer camps or family vacations that are nature oriented e. Because these areas are critical to the conservation of biodiversity, the designation of more areas for protection and increases in the sizes of those areas already in existence are necessary. Amphibians are one of the earth's most imperiled vertebrate groups, with approximately one-third of all species facing extinction Stuart et al. In many cases, these organizations provide updates on the status of endangered species and promote letter writing to elected officials in requesting protection for endangered species and their habitats. In many cases, multiple causes act in concert to threaten populations. Zoos and aquariums have limited space, however, so to maintain healthy populations, they cooperate in managing their collections as breeding populations from international to regional levels. Fish 15 spp. Diversity and Distributions 9 , Davic, R. So what is being done to preserve amphibian diversity? Each taxon is appraised using all criteria. To date, sites encompassing threatened species of mammals, birds, reptiles, amphibians, conifers and corals have been identified. These studbooks are used to make recommendations regarding which individuals should be bred, how often, and with whom in order to minimize inbreeding and, thus, enhance the demographic and genetic security of the captive population. Category VI Managed Resource Protected Area: protected area managed mainly for the sustainable use of natural ecosystems Definition: Area containing predominantly unmodified natural systems, managed to ensure long term protection and maintenance of biological diversity, while providing at the same time a sustainable flow of natural products and services to meet community needs. The most common are creation of protected areas, captive breeding and reintroduction, conservation legislation, and increased public awareness. Members of these organizations worldwide participate in captive amphibian husbandry and breeding programs using wild-caught individuals Figure In concert with such activities, some facilities are also addressing the possibility of 'biobanking' activities, such as cryogenically preserving the sperm and eggs of imperiled species or maintaining living cell lines for future use. Early positive experiences with nature are essential for children to gain an appreciation for wildlife and the problems species face. In addition to designation of new protected areas, efforts of the ASG include habitat restoration, promotion of ecotourism, and extended amphibian-monitoring programs. Reintroductions can also utilize individuals from healthy wild populations, meaning individuals that are thriving in one part of the range are introduced to an area where the species was extirpated. A series of quantitative criteria is measured for inclusion in these categories, including: reduction in population size, geographic range size and occupancy of area, total population size, and probability of extinction. The AZE focuses on species whose habitats have been degraded or whose ranges are exceptionally small, making them susceptible to outside threats. Table 4. Well-planned and -managed protected areas not only benefit species at risk, but other species associated with them, thereby increasing the overall amount of biodiversity conserved. An effective and internationally recognized strategy for conserving species and ecosystems is to designate protected areas. In high school, this education is continued through formal science education and extra-curricular activities. Other means of increasing public awareness involve internet websites where subscribers can receive emails from conservation organizations like Defenders of Wildlife, Environmental Defense, and World Wildlife Fund. At the highest levels of threat, taxa are listed as 'Critically Endangered,' 'Endangered,' or 'Vulnerable,' all of which are given 'Threatened' status. Treatment of chtridiomycosis requires urgent clinical trials. However, reintroduction is only feasible if survival can be assured. Figure 5 Wild-caught and captive-bred amphibians are maintained in facilities, such as those pictured above, at the Atlanta Botanical Gardens, as part of the Amphibian Ark's mission of preserving amphibian biodiversity in the wake of global population declines. Diseases of Aquatic Organisms 92 , Collins, J. Global amphibian declines: sorting the hypotheses. There are a variety of methods currently being implemented to save endangered species. Reptiles 76 spp. International trade in wildlife is a multi-billion dollar industry that affects millions of plants and animals. The ASG's 'Metamorphosis' initiative utilizes artistry to promote increase public recognition of connections between the plight of amphibians and that of humanity. Perhaps the most important tools in managing these programs are studbooks, which ensure that captive populations maintain a sufficient size, demographic stability, and ample genetic diversity. The goal of such efforts is to prevent the most imminent species extinctions by increasing global awareness of these key areas. Establishing captive populations is an important contribution of zoos and aquariums to the conservation of endangered species. Annual Review of Ecology, Evolution, and Systematics 35 , {/INSERTKEYS}{/PARAGRAPH} All rights reserved. Amphibians typically do not receive the attention bestowed upon more charismatic megafauna, such as pandas and tigers, despite their significant economic, ecological, and aesthetic values. Approximate number of species spp. In addition, some conservation efforts, such as Project Golden Frog, utilize attractive or otherwise conspicuous amphibians as flagship species with which to garner public interest and local pride in endangered species and promote local activism Figure 7. Due to the rapidity with which Bd invades amphibian communities, swift conservation action was deemed necessary to prevent extinctions; consequently, many institutions realized the necessity of collecting wild individuals prior to the arrival of Bd with the hopes of establishing captive populations. Most important, CITES does not take the place of national laws; member countries must also have their own domestic legislation in place to execute the Convention. Although the exact origins of this pathogen are currently debated, Bd has been detected throughout the world and linked to dramatic amphibian population declines and extinctions Skerratt et al. All information pertinent to management of the species in question is included e. These data are collected from national and regional governing bodies and non-governmental organizations. Reintroduction programs involve the release of individuals back into portions of their historic range, where they are monitored and either roam freely e. Public awareness can be increased through education and citizen science programs. As a result, CITES lists species in three Appendices according to the level of protection they require to avoid over-exploitation; species listed in Appendix I require the most protection and, thus, trade limitations Table 3. Since , there has been a dramatic increase in the global number and extent of nationally designated protected areas Figure 2. Some species in danger of extinction in the wild are brought into captivity to either safeguard against imminent extinction or to increase population numbers. See iucnredlist. Batrachochytrium dendrobatidis is a parasitic fungus that disrupts the bodily processes of its amphibian hosts, resulting in lethargy and ultimately death. However, member countries adhere to regulations voluntarily and, consequently, they must implement them. There are a variety of human activities that contribute to species becoming threatened, including habitat destruction, fragmentation, and degradation, pollution, introduction of non-native species, disease, climate change, and over-exploitation. Figure 6 See figure 5 legend. Though the causes underlying population declines are numerous, some traits serve as predictors of whether species are likely to be more vulnerable to the causes listed. In addition, the recent declines observed in relatively pristine areas, such as state, provincial, and national parks worldwide have brought to light the tremendous impact of pathogens on amphibian populations, most notably that of the amphibian-killing fungus Batrachochytrium dendrobatidis Bd. The conspicuousness and charisma of this species in particular is being used to draw attention to the plight of amphibian populations worldwide. The primary goals of captive breeding programs are to establish populations via controlled breeding that are: a large enough to be demographically stable; and b genetically healthy Ebenhard Successful captive breeding programs include those for the Guam rail, scimitar-horned oryx, and Przewalski's horse. Another goal of some captive breeding programs is to reintroduce animals to the wild to reestablish populations. To address the historic sources of amphibian population declines, such as overexploitation and habitat loss, national and international legislation exists to monitor the trade in amphibians and prevent further reductions in available habitat. This species is listed as vulnerable by IUCN, and both the species and its habitat are afforded protection as a threatened species as defined by the United States Endangered Species Act and. Despite efforts to preserve suitable habitat, biologists became increasingly aware of catastrophic population declines associated with Bd, and more urgent action became necessary when declines were detected in protected areas with minimal risks of habitat loss and overexploitation. {PARAGRAPH}{INSERTKEYS}This page has been archived and is no longer updated. However, since not all criteria are appropriate for assessing all taxa, satisfying any one criterion qualifies listing at that designated threat level. In general, the public is unaware about the current extinction crisis. Also, biologists are increasingly advocating for more rigorous chytrid monitoring protocols to prevent further spread of this pathogen, such as efforts in the United States to incorporate amphibians into the Lacey Act , a federal mandate that would require them to be certified as disease-free prior to importation. The trade in wildlife is an international issue and, as such, cooperation between countries is required to regulate trade under CITES. Amphibians 17 spp. Treatment methods are currently being investigated for amphibians already infected with Bd Berger et al. Plants spp. Safeguarding the integrity of this traditional interaction is vital to the protection, maintenance and evolution of such an area. While some researchers are dedicated to maintaining captive populations, others are actively investigating potential treatments for Bd or preventative measures. Another opportunity for creating protected areas is the Alliance for Zero Extinction AZE , an international consortium of conservation organizations that specifically targets protection of key sites that represent sanctuaries of one or more Endangered or Critically Endangered species.
