For the other species of plants and animals whose survival is threatened, a range of management and conservation measures are in place.
Any person may nominate a native species, ecological community or threatening process for listing under the EPBC Act.

  Threatened species - Wikipedia, the free encyclopedia
Species which are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical mesaure of biomass related to population growth rate.
Although threatened and vulnerable may be used interchangeably when discussing IUCN categories, the term threatened is generally used to refer to the three categories (critically endangered, endangered and vulnerable), while vulnerable is used to refer to the least at risk of those three categories.
Threatened species are also referred to as a red-listed species, as they are listed in the IUCN Red List of Threatened Species.

 IUCN Red List of Threatened Species
Threatened species are not randomly distributed across orders and families.
Countries with the most threatened and the most threatened endemic species tend to lie within the continental tropics and countries with the highest proportion of threatened species are mostly tropical island nations.
For threatened amphibians, the major threats are different, with 29% of species being affected by pollution (including climate change) and 17% by disease (particularly chytridiomycosis).

 eMedicine - Threatened Abortion : Article by Millie Behera, MD, FRCPSC
Background: Threatened abortion is a clinically descriptive term that applies to women who are at less than 20 weeks' gestation, have vaginal spotting or bleeding, a closed cervical os, and, possibly, mild uterine cramping.
Threatened abortion is defined by the absence of passing/passed tissue and the presence of a closed cervical os.
In most instances of threatened abortions that ultimately result in complete abortion, the embryo is already dead; thus, the administration of progesterone drugs is ineffective and only prolongs the natural course of abortion.

 EPA: Pesticides Endangered and Threatened Species
Threatened species are plants and animals whose numbers are very low or decreasing rapidly.
Threatened species are not endangered yet, but are likely to become endangered in the future.
For example, if a fish such as the shortnose sturgeon becomes extinct, all of the species that rely on it for food will also suffer and may become threatened or endangered.

 Teachers threatened with injury or attacked by students - Indicators of School Crime and Safety, 2003
The survey results indicate that a smaller percentage of elementary and secondary school teachers were threatened with injury by a student at their school in the 1999—2000 school year than in the 1993—94 school year (9 vs. 12 percent) (table 10.1).
In both survey years, teachers in central city schools were more likely to be threatened with injury or physically attacked than teachers in urban fringe or rural schools (figure 10.1 and tables 10.1 and 10.2).
Secondary school teachers were more likely than elementary school teachers to have been threatened with injury by a student (10 vs. 8 percent); however, secondary school teachers were less likely to have been physically attacked (2 vs. 6 percent).

 DPIW - Threatened Species Strategy   (Site not responding. Last check: 2007-10-25)
The success of these actions in mitigating each threatening process is measured with a range of performance indicators that are outlined for each process.
Addressing threatening processes as opposed to an individual species approach is not only efficient but more cost effective as single actions may help the conservation of several species.
The need may be urgent, there may be a number of threatening processes at work or there may be no particular process affecting the species but an action which can be simply addressed to conserve the species.

 Endangered, threatened & special concern species: Minnesota DNR
A species is considered threatened if the species is likely to become endangered within the foreseeable future throughout all or a significant portion of its range within Minnesota.
Species on the periphery of their range that are not listed as threatened may be included in this category along with those species that were once threatened or endangered but now have increasing or protected, stable populations.
Note that the federal Endangered Species Act of 1973, as amended (16 USC 1531 - 1544) requires the U.S. Department of the Interior to identify species as endangered or threatened according to a separate set of definitions, and imposes a separate set of restrictions pertaining to those species.

While a few of these species (such as lake sturgeon, round whitefish, and mooneye) may be familiar to some people, the majority of them are small, inconspicuous species rarely seen by anyone.
Reasons for their population decline are attributed to: overexploitation due to high demand for caviar and smoked flesh; construction of dams that cut off spawning and nursery areas; and some pollution and degradation of habitat.

 Protecting Threatened and Endangered Species
Once a population of animals is reduced by one or more of these human activities, it may be unable to withstand natural limiting factors in the wild—such as predation, limited food supply, or disease—that it might otherwise have survived.
A "threatened" species is one that is likely to become endangered in the foreseeable future.
However, if a particular species is federally listed as threatened or endangered (or otherwise protected at the federal level), any protections provided by the state must be at least as restrictive as those provided at the federal level.

To list a species as a threatened species or an endangered species under ORS 564.100 to 564.130, the director shall determine that the natural reproductive potential of the species is in danger of failure due to limited population numbers, disease, predation or other natural or man-made factors affecting its continued existence.

 Near Threatened - Wikipedia, the free encyclopedia
Near Threatened (NT) is an conservation status assigned to species or lower taxa which may be considered threatened with extinction in the near future, although it does not currently qualify for the threatened status.
The rationale used for Near Threatened taxa usually includes the criteria of Vulnerable which are plausible or nearly met, such as reduction in numbers or range.
Near Threatened species may also include those which are dependent on conservation efforts to prevent their becoming threatened.

 Threatened Fauna Adviser
Knowledge of the threatened fauna and the recommendations needed for forest operations was already known by the Senior Zoologist, and other specialists working in Tasmania.
The presence of a threatened species need not prevent a forest operation, but it does affect the way in which the operation should best be conducted.
An important outcome of the development of Threatened Fauna Adviser is that the zoologists have had the opportunity to think through all the possible scenarios and write appropriate recommendations, rather than having to produce case by case recommendations for each application to harvest timber.
