Bay Area is Home to More than 100 Species on the Federal Endangered and Threatened Species List
The global extinction crisis rivals global warming in its magnitude, urgency, and monumental implications for human health and welfare. Extinction is irreversible, and is now happening at a breakneck pace: across the globe, between one and 100 species are becoming extinct every day. The natural "background" rate of extinction is only one species per 100 years. Species loss signals a potential risk to humans as well as to animals and plants. More sensitive animals those that fill highly specialized niches, require large tracts of undisturbed land, or breed slowly, for instance are the first to suffer from habitat loss, pollution, and other drastic human-induced changes. In time, as the food chain collapses, animals further up will also suffer including humans. Species populations can be revitalized if serious efforts are made. For instance, the California brown pelican like the bald eagle was seriously affected by the use of DDT, which weakened the bird's eggshells so that they cracked during incubation. With the banning of DDT and other toxic pesticides, the brown pelican population is slowly rebounding. Closer to home, the South Bay's fragile population of California clapper rails has rebounded in the past decade, climbing from between 200 and 300 in 1991 to an estimated 600 to 700 in 1999 as a result of controls on invasive species.

What is the endangered species act of 1973?
The Endangered Species Act (ESA) of 1973 and was developed to protect plant and animal species that were in danger of becoming extinct.
The Endangered Species Act of 1973 was passed to protect plant and animal species that could be placed on the threatened or endangered list by the Secretary of the Interior. The listing process is based on population data and enforcement is handled by the Fish and Wildlife Service (FWS). The FWS is responsible for protecting a species against further demise and for creating plans for the recovery of each species and determining the species critical habitat. The critical habitat is the area that is required by the species for its survival and conservation. A designated critical habitat does not necessarily need to be presently occupied by the species, but is deemed necessary for its conservation. The process of authorizing a critical habitat includes the FWS placing the information in the Federal Register and then soliciting public opinion, which is then considered. The critical habitat designation includes consideration of the spatial area needed by a species to allow for territorial range and population growth, adequate nesting, shelter or coverage, sufficient food and water resources and breeding sites. Before the actual designation of the habitat, an economic analysis is done, but if the area would be needed to prevent extinction of a species, the habitat can still be listed regardless of the economic impact.

) is dedicated to working with others to conserve, protect, and enhance fish, wildlife, and plants and their habitats, and reverse the alarming trend of human-caused extinctions that threatened the ecosystems we all share.
Why should we be concerned about the loss of species? Extinction is a natural process. Normally, new species develop through a process known as speciation at about the same rate that other species become extinct. However, because of air and water pollution, over-hunting, extensive deforestation, the loss of wetlands, and other man-induced impacts, extinctions are now occurring at a rate that far exceed the speciation rate. Each extinction diminishes the diversity and complexity of life on Earth. The loss of a single species may seem insignificant. However, all life on earth is interconnected. If enough "living connections" are broken, entire ecosystems could fail and the balance of nature could be forever altered.
The United States Congress recognized that many of our Nation's valuable plant and wildlife resources have been lost and that others are imperiled. The

Their reproductive rates are lower than their mortality rates over long periods of time, so their numbers are diminishing. The reasons for this are varied, but lately, very often involves a loss of habitat as people encroach on their living areas. When a species is listed as endangered or threatened, it is not a death sentence. Many animals, like the bald eagle and the American alligator, were on the brink of extinction and are now recovering. Many species, however, will not recover, and could be lost forever. Throughout time, animal species have been going extinct (long before people evolved); paleontologists estimate that well over 90 percent of all plant and animal species that ever existed have gone extinct.

( Evaluation ) ( Top ) ( Background ) ... ( Search Engines ) BACKGROUND
T he delicacy of the earth is amazing. Every organism on the earth has some connection with another. Therefore, if one organism is stressed, it can affect other surrounding organisms. When the population of certain species begins to dwindle, it is easy to think that species is the only one to suffer. This is not the case since each organism is in some way linked to one another. E xtinction is a natural process, but recently the rate of species becoming Extinct has increased dramatically. Much of this has resulted from the lack of respect humans have shown for the delicate ecosystem we live in. E ach biome depends on the successfulness of the communities within it, just as each community thrives on the stability of the populations of the species within it. Through the subtraction of species through E xtinction we jeopardize the balance and diversity of the ecosystem.

Endangered Species will survive with YOUR help! Facts About Endangered Species
According to scientists, more than one and one-half million species exist on the earth today. However, recent estimates state that at least 20 times that many species inhabit the planet. In the United States, 735 species of plants and 496 species of animals are listed as threatened or endangered. 266 of these listed species have recovery plans currently under development. There are more than 1,000 animal species endangered worldwide. There are more than 3,500 protected areas in existence worldwide. These areas include parks, wildlife refuges and other reserves. They cover a total of nearly 2 million square miles (5 million square km), or 3% of our total land area. Aquatic species, which are often overlooked, are facing serious trouble. One third of the United States’ fish species, two-thirds of its crayfish species, and almost three-quarters of its mussel species are in trouble. Endangered Species Terms VULNERABLE SPECIES A species particularly at risk because of low or declining numbers or small range, but not a threatened species.

Canada's Endangered Species
256 Canadian species are listed by the Scientific Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as being extinct, extirpated, endangered, threatened and vulnerable. The list only includes Canada's vertebrate and vascular plant species and was released in April 1994. Definitions are: Extinct - a species formerly indigenous to Canada that no longer exists anywhere. Extirpated - a species no longer existing in the wild in Canada but occurring elsewhere in the world. Endangered - a species threatened with imminent extinction or extirpation throughout all or a significant portion of its Canadian range. Threatened - a species likely to become endangered in Canada if the factors affecting its vulnerability are not reversed. Vulnerable - a species particularly at risk because of low or declining numbers, small range or for some other reason, but not a threatened species.
Extinct - 9 species

Search for Species
Through this search you can look for information on globally threatened species. Currently species in all categories except for Least Concern are available. You can find a particular species or group set of species by specifying a number of different criteria. You can select species by either picking a family (listed in taxonomic order), entering free text for a genus, species or common name (in English only as this stage, although common names in other languages will be added in the future). For example, to find all cranes, you could enter “%crane” into the common name field (where % is a wild card) or “grus” into the genus field or select “GRUIDAE (Cranes)” from the family field. Search can also be restricted by region, country or IUCN Red List category. For example, to select all “extinct” species, tick the extinct check box and click search. Coming soon - already released on CD, Threatened Birds of the World 2004 will be available here in May.

wolves are generally quiet, peaceful creatures unless they have been frightened or are starving. They are more afraid of

Knoxia sumatrensis - presumed extinct species listing
Knoxia sumatrensis (Retz.) DC. is listed as PRESUMED EXTINCT on the schedules of the NSW Threatened Species Conservation Act. Two major sources were used in deciding to list the species at the introduction of the Threatened Species Conservation Act in 1995: 1. The Rare or Threatened Australian Plants (ROTAP) list The ROTAP list identifies plants that are at risk nationally. It's the result of research by botanical experts, who started developing the list in 1979. A number of plant species on ROTAP have been listed as vulnerable, endangered or presumed extinct in the NSW Threatened Species Conservation Act. 2. NPWS review of plants across the state The NPWS developed a draft threatened plant list for NSW, using standardised risk assessment criteria. This project was used to:
  • develop the initial plant listings for the NSW Threatened Species Conservation Act
  • revise the assessment of several species that had been identified as rare or threatened in ROTAP.

Rarity and Extinction
The role of rarity in the recognition and classification of threatened and endangered species is unclear. To some, rarity and the threat of extinction are almost synonymous and it is widely assumed that rarity is associated with increased extinction risk, while others recognize that rarity per se is insufficient to classify a species as being at high risk of extinction. Some rare species persist and they do so because they have biological characteristics that allow them to become rare and yet then enable them to endure in such a state. But where there are processes causing a continual decline in numbers, a species may well be at risk. A better understanding of the causes and consequences of rarity would assist greatly in the setting of conservation priorities.
Variations on the Extinction Theme
Although extinction is usually defined as the total disappearance of a species from the face of the earth and an absence of sightings for a period of at least five decades, it is important to recognize that there are variations on this somewhat strict definition.

About IUCN
Members News Our Work ... Publications The IUCN Red List of Threatened Species
The IUCN Red List is the world's most comprehensive inventory of the global conservation status of plants and animals. It uses a set of criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. There are nine Categories of Threat in the IUCN Red List system: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern Data Deficient , and Not Evaluated . A species is listed as threatened if it falls in the Critically Endangered, Endangered or Vulnerable categories.
The overall aim of the IUCN Red List is to convey the urgency and scale of conservation problems to the public and policy-makers, and to motivate the global community to try to reduce species extinctions.
