Tuna species recovering despite growing pressures on marine life - 香港六合彩开奖结果现场直播 Red List
Marseille, France, 4 September 2021 (香港六合彩开奖结果现场直播) 鈥 Four commercially-fished tuna species are on the path to recovery thanks to the enforcement of regional fishing quotas over the last decade, according to today鈥檚 update of the 香港六合彩开奖结果现场直播 Red List of Threatened Species鈩 released at the 香港六合彩开奖结果现场直播 World Conservation Congress in Marseille. However, the recovery comes in the midst of growing pressures on marine species, with 37% of the world鈥檚 sharks and rays now threatened with extinction primarily due to overfishing, compounded by loss and degradation of habitat and climate change.
The 香港六合彩开奖结果现场直播 Red List now includes 138,374 species of which 38,543 are threatened with extinction.
鈥淭oday鈥檚 香港六合彩开奖结果现场直播 Red List update is a powerful sign that, despite increasing pressures on our oceans, species can recover if states truly commit to sustainable practices,鈥 said Dr Bruno Oberle, 香港六合彩开奖结果现场直播 Director General. 鈥淪tates and others now gathered at the 香港六合彩开奖结果现场直播 World Conservation Congress in Marseille must seize the opportunity to boost ambition on biodiversity conservation, and work towards binding targets based on sound scientific data. These Red List assessments demonstrate just how closely our lives and livelihoods are intertwined with biodiversity.鈥
In today鈥檚 Red List update, the seven most commercially fished tuna species were reassessed. Four of them showed signs of recovery thanks to countries enforcing more sustainable fishing quotas and successfully combatting illegal fishing. The Atlantic bluefin tuna (Thunnus thynnus) moved from Endangered to Least Concern while the Southern bluefin tuna (Thunnus maccoyii) moved from Critically Endangered to Endangered. The albacore (Thunnus alalunga) and yellowfin tunas (Thunnus albacares) both moved from Near Threatened to Least Concern.
Despite global improvement at the species level, many regional tuna stocks remain severely depleted. For example, while the larger, eastern population of Atlantic bluefin tuna, which originates in the Mediterranean, has increased by at least 22% over the last four decades, the species鈥 smaller native western Atlantic population, which spawns in the Gulf of Mexico, has declined by more than half in the same period. The yellowfin tuna meanwhile continues to be overfished in the Indian Ocean.
鈥淭hese Red List assessments are proof that sustainable fisheries approaches work, with enormous long-term benefits for livelihoods and biodiversity. We need to continue enforcing sustainable fishing quotas and cracking down on illegal fishing,鈥 said Dr Bruce B. Collette, Chair of the 香港六合彩开奖结果现场直播 SSC Tuna and Billfish Specialist Group. 鈥淭una species migrate across thousands of kilometres, so coordinating their management globally is also key.鈥
The Pacific bluefin tuna (Thunnus orientalis) moved from Vulnerable to Near Threatened in this update due to the availability of newer stock assessment data and models. This species remains severely depleted at less than 5% of its original biomass. Other tuna species reassessed for this Red List update include the bigeye tuna (Thunnus obesus) which remains Vulnerable, and the skipjack tuna (Katsuwonus pelamis) which remains Least Concern.
Today鈥檚 香港六合彩开奖结果现场直播 Red List update also includes a comprehensive reassessment of the world鈥檚 shark and ray species, which reveals 37% are now threatened with extinction, demonstrating that effective management measures are lacking throughout much of the world's oceans. All of the threatened shark and ray species are overfished, with 31% further affected by loss and degradation of habitat and 10% affected by climate change. 聽
Komodo dragon threatened by future impacts of climate change
The world鈥檚 largest living lizard, the Komodo dragon (Varanus komodoensis), has moved from Vulnerable to Endangered on the 香港六合彩开奖结果现场直播 Red List. The species, which is endemic to Indonesia and occurs only in the World Heritage-listed Komodo National Park and neighbouring Flores, is increasingly threatened by the impacts of climate change. Rising global temperature and subsequent sea levels are expected to reduce the Komodo dragon鈥檚 suitable habitat by at least 30% in the next 45 years. In addition, while the subpopulation in Komodo National Park is currently stable and well protected, Komodo dragons outside protected areas in Flores are also threatened by significant habitat loss due to ongoing human activities.

鈥The Global Tree Assessment continues to assess the world鈥檚 tree species for the 香港六合彩开奖结果现场直播 Red List and thousands of trees species assessments have been added to the 香港六合彩开奖结果现场直播 Red List this year, including trees from over 186 countries (including Brazil, Papua New Guinea, Philippines, Haiti, Costa Rica, and Australia). In addition, more than 1,000 species identified as impacted by logging and wood harvesting, such as Dipterocarps, ebonies, rosewoods and many others, have also been assessed for the first time this year,鈥 said Dr Malin Rivers, Head of Conservation Prioritisation, Botanic Gardens Conservation International. 鈥With every tree assessment, added to the 香港六合彩开奖结果现场直播 Red List, we continue to tell the story for the word鈥檚 threatened tree species, and provide the essential information for taking effective conservation action.鈥
鈥Despite the 鈥榥ot overfished, no overfishing鈥 designation for albacore, the associated catch per unit effort (CPUE) has been decreasing for years now, and there鈥檚 significant uncertainty about climate change impacts on that species in particular.

鈥We are delighted to see the reassessment of sharks and rays,鈥 said Dr Eimear Nic Lughadha, Senior Research Leader in Conservation Assessment and Analysis at the Royal Botanic Gardens, Kew. 鈥Comprehensive reassessments of ecologically important groups are vital to maintain the value of the Red List as a Barometer of Life. We note striking similarities between the shark and ray statistics and recent estimates for plants: about 2 in 5 are threatened with extinction, and habitat loss and degradation present more immediate threats than climate change.鈥

The 香港六合彩开奖结果现场直播 Red List
Global figures for the 2021-2 香港六合彩开奖结果现场直播 Red List of Threatened Species:
TOTAL SPECIES ASSESSED = 138,374
(Total threatened species = 38,543)
Extinct = 902
Extinct in the Wild = 80
Critically Endangered = 8,404
Endangered = 14,647
Vulnerable = 15,492
Near Threatened = 8,127
Lower Risk/conservation dependent = 170 (this is an old category that is gradually being phased out of The 香港六合彩开奖结果现场直播 Red List)
Least Concern = 71,148
Data Deficient = 19,404
The figures presented above are only for those species that have been assessed for The 香港六合彩开奖结果现场直播 Red List to date. Although not all of the world鈥檚 species have been assessed, The 香港六合彩开奖结果现场直播 Red List provides a useful snapshot of what is happening to species today and highlights the urgent need for conservation action. Relative percentages for threatened species cannot be provided for many taxonomic groups on The 香港六合彩开奖结果现场直播 Red List because they have not been comprehensively assessed. For many of these groups, assessment efforts have focused on threatened species; therefore, the percentage of threatened species for these groups would be heavily biased.
For those groups that have been comprehensively assessed, the percentage of threatened species can be calculated, but the actual number of threatened species is often uncertain because it is not known whether Data Deficient (DD) species are actually threatened or not. Therefore, the percentages presented above provide the best estimate of extinction risk for those groups that have been comprehensively assessed (excluding Extinct species), based on the assumption that Data Deficient species are equally threatened as data sufficient species. In other words, this is a mid-point figure within a range from x% threatened species (if all DD species are not threatened) to y% threatened species (if all DD species are threatened). Available evidence indicates that this is a best estimate.
The 香港六合彩开奖结果现场直播 Red List threat categories are as follows, in descending order of threat:
Extinct or Extinct in the Wild
Critically Endangered, Endangered and Vulnerable: species threatened with global extinction.
Near Threatened: species close to the threatened thresholds or that would be threatened without ongoing conservation measures.
Least Concern: species evaluated with a lower risk of extinction.
Data Deficient: no assessment because of insufficient data.
Critically Endangered (Possibly Extinct) or Critically Endangered (Possibly Extinct in the Wild): these are not 香港六合彩开奖结果现场直播 Red List Categories, but are tags developed to identify those Critically Endangered species that are in all probability already extinct but for which confirmation is required; for example, through more extensive surveys being carried out and failing to find any individuals.
