Twenty five per cent of fresh water fish at risk of extinction, IUCN


DUBAI: 1 / 4 of freshwater fish species worldwide are susceptible to extinction, in keeping with an replace to the worldwide pink checklist of threatened species on Monday (Dec 11), highlighting the escalating impacts of human-caused local weather change on the planet’s wildlife.

The Worldwide Union revealed the evaluation for Conservation of Nature (IUCN), as world representatives met within the UAE for the COP28 climate change summit.

The IUCN additionally up to date its checklist to replicate local weather change threats to Atlantic Salmon, inexperienced turtles and Huge leaf mahogany bushes.

“Local weather change is menacing the range of life our planet harbours and undermining nature’s capability to satisfy fundamental human wants,” IUCN Director Common Grethel Aguilar stated in a press release.

Of the almost 15,000 freshwater fish species assessed, 25 per cent have been susceptible to extinction and of these not less than 17 per cent have been struggling penalties of local weather change, together with fluctuating water ranges and shifting seasons.

The IUCN ranks a species’ threat of extinction alongside 9 classes starting from “not evaluated” to “extinct”.

GLOBAL WARMING KILLING ATLANTIC SALMON 

Atlantic salmon skilled a 23 per cent lower between 2006 and 2020, rising alongside the checklist from of “least concern” to “close to threatened”.

International warming is affecting “all phases” of its lifecycle – decreasing prey, permitting invasive species to broaden, and growing deaths of younger salmon resulting from water air pollution linked principally to logging and agriculture, IUCN stated in a press release.

Inexperienced turtles within the Central South Pacific and East Pacific have been categorised as “endangered” and “susceptible” respectively within the replace.

Rising sea temperatures lower hatching success and cut back the seagrass inexperienced turtles depend on for meals. Rising sea ranges flood nests and drown the younger, whereas grownup turtles are sometimes caught and killed as a by-product of commercial fishing.

The massive leaf mahogany tree was reclassified from “susceptible” to “endangered” as a result of unsustainable harvesting of sought-after timber and agricultural encroachment on the tropical forests the place it grows.

SOME CONSERVATION EFFORTS WORKING

However the up to date checklist additionally confirmed the facility of conservation efforts.

The scimitar-horned oryx improved from “extinct within the wild” to “endangered” after conservationists efficiently reintroduced the species in Chad.

The beforehand “critically endangered” saiga antelope rose to “close to threatened” on the checklist. Between 2015 and 2022 its inhabitants, dwelling principally in Kazakhstan, elevated by 1,100% because of stringent anti-poaching measures and enforcement.

However each species are susceptible to rising threats from local weather change within the areas the place they reside.

The scimitar-horned oryx faces extra frequent and extreme droughts within the Sahel area of Africa. And in 2015 saiga antelopes suffered “mass mortality” resulting from “abnormally excessive temperatures and humidity” within the area, in keeping with the authors.

“To make sure the outcomes of conservation motion are sturdy, we have to decisively deal with the interlinked local weather and biodiversity crises,” stated IUCN President Razan Al Mubarak.

The IUCN Purple Record now consists of 157,190 species, of which 44,016 are threatened with extinction.

The up to date checklist comes as nations race towards the clock to achieve an settlement throughout this yr’s COP28 local weather convention in Dubai, scheduled to finish Tuesday.
