Conservation biology is a mission-oriented science that focuses on how to protect and restore biodiversity, or the diversity of life on Earth. Like medical research, conservation biology deals with issues where quick action is critical and the consequences of failure are great..
Are rare species more important to conserve?
rare species contribute to their ecosystems and support human life in a variety of unique, often unconventional ways, such as keystone species or plants that support soil fertility; likewise preserving rare species can have a direct positive impact on human life..

What is the concept of rare species?
A rare species is a group of organisms that are very uncommon, scarce, or infrequently encountered. This designation may be applied to either a plant or animal taxon, and is distinct from the term endangered or threatened..

Some species require large home ranges or habitat patch sizes, some have low dispersal abilities or low reproductive rates, some are highly localized or have a restricted distribution (endemic species), and some concentrate their populations during some time of the year (such as bats clustering in hibernacula).

Should we redouble global efforts to conserve rare species?
Ultimately, rare species, by definition, are more prone to reductions in population size and extinction and should be high priorities for conservation ( 4, 5) . Our results suggest that redoubling global efforts to conserve rare species is needed and that we have a closing window to do so.

What are ecologically rare and common species?
To overcome this limitation, we used the intersection of both distributions:
we thus defined ecologically rare and common species as those having values of both functional distinctiveness and geographical restrictiveness higher than 75% or lower than 25% of the entire species pool
respectively (Fig. 1 ).
,
What fraction of biodiversity consists of rare species?
A key feature of life’s diversity is that some species are common but many more are rare. Nonetheless, at global scales, we do not know what fraction of biodiversity consists of rare species. Here, we present the largest compilation of global plant diversity to quantify the fraction of Earth’s plant biodiversity that are rare.
,
Which order has the highest concentration of ecologically rare species?
The orders with the highest concentration of ecologically rare species were the Primates and Chiroptera for mammals and Psittaciformes, Caprimulgiformes and Apodiformes (Strisores) for birds. Finally, we found that ecologically rare species were on average no more evolutionary distinct than other species (see Supplementary Fig. 3 ).

Species of organisms facing a very high risk of extinction
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Version 2014.2 of the IUCN Red List of Threatened Species identified 4574 Critically Endangered species, subspecies and varieties, stocks and subpopulations.

Topics referred to by the same term
Group of organisms that are very uncommon, scarce, or infrequently encountered
A rare species is a group of organisms that are very uncommon, scarce, or infrequently encountered. This designation may be applied to either a plant or animal taxon, and is distinct from the term endangered or threatened. Designation of a rare species may be made by an official body, such as a national government, state, or province. The term more commonly appears without reference to specific criteria. The International Union for Conservation of Nature does not normally make such designations, but may use the term in scientific discussion.
Threatened species are any species which are vulnerable to extinction
IUCN conservation category
Threatened species are any species which are vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment.
