Most species at greatest risk from climate change
are not currently conservation priorities, finds an IUCN study
In what
can be a major finding, species which are currently not under conservation
priorities have been found to be at greater risk from climate change than those
species that are under conservation priorities.
A paper
published in the journal PLOS ONE revealed that species that have not made to
the International Union for Conservation of Nature (IUCN) Red List of Threatened
Species are more prone to the affects of climate change.
The study
is one of the biggest of its kind, assessing all of the world’s birds,
amphibians and corals, on the work of more than 100 scientists and over a
period of five years.
According
to the study, out of the 16,857 species assessed, up to 83% of birds, 66% of
amphibians and 70% of corals that were identified as highly vulnerable to the
impacts of climate change are not
currently considered threatened with extinction on the IUCN Red List of
Threatened Species.
“They are
therefore unlikely to be receiving focused conservation attention,” states the
study.
It was
found that only 6-9% of the bird species, 11-15% of the amphibian, and 6-9%
coral species are both highly climate change vulnerable and are already
threatened with extinction on the IUCN Red List.
According
to the leader of the Study, Wendy Foden of IUCN Global Species Program, the
findings revealed alarming surprises.
“We
hadn’t expected that so many species and areas that were not previously
considered to be of concern would emerge as highly vulnerable to climate
change.
Wendy
Foden added that if conservation efforts carry on as usual without taking
climate change into account, it will be late to help many of the species and
areas that need it most.
The study
looked at the unique biological and ecological characteristics that make species
more or less sensitive or adaptable to climate change. The conventional methods
have focused largely on measuring the amount of change to which species are
likely to be exposed.
The
Amazon emerges as a region of high climate change vulnerability for both birds
and amphibians, due to the large overall number and proportions of such species
occurring there. For birds, large numbers of highly climate change vulnerable
species are found in Mesoamerica, central Eurasia, the Congo basin, the
Himalayas and Sundaland.
For
amphibians, in addition to the Amazon, high proportions of highly climate
change vulnerable species occur in Mesoamerica, the northern Andes, North
Africa, and eastern Russia to Mongolia, the Himalayas, and the western Arabian
Peninsula. The highly climate change vulnerable corals are concentrated in the
Coral Triangle, Sumatra and Java.
According
to MacArthur Foundation, the major funder of the study, keeping ecosystems
healthy and intact will play a key role in helping human societies adapt to
changing climates and by highlighting those species in need of the most urgent
attention, the study helps to show the parts of the world where this needs to
be focused.
“We
cannot afford to be complacent about the study’s results. Highly climate change
vulnerable species require targeted action to help them adapt to on-going and
future climate,” says a key investigator of the study, Stuart Butchart, Head of
Science at BirdLife International.
