From frogs to springsnails – IUCN Red List update (10th November 2011)

The latest IUCN Red List update brings the total number of species reviewed to more than 61,900. Alarmingly, 25% of mammals are at risk of extinction, and the Western Black Rhino has now been declared extinct. However, there’s also a glimmer of hope with the present update highlighting a number of conservation successes, such as an increase in the population of Southern White Rhino to over 20,000 individuals.

ZSL and collaborators’ work on the Sampled Red List Index has contributed new assessments of plants, butterflies and freshwater molluscs to this latest update. Plant species are now much better represented, and 300 species of butterfly and more than 800 freshwater mollusc species have now been added or updated.

If you go down to the woods tomorrow... (29th August 2011)

The Living Planet Index has many applications and can be used to assess regional population trends. We are currently working with the Rewilding Europe initiative to produce an in depth report on European vertebrate trends in the past 50 years.

'Rewilding' is a landscape scale approach to conservation. This project focuses on returning areas abandoned by humans back into suitable habitat for native wildlife (such as bears, storks and ibex) and provide benefits humans through tourism and ecosystem services.

Looking ahead: Predicting species extinctions (18th August 2011)

Global species extinction typically represents the end point in a long sequence of population declines and local extinctions. In local population level studies there are limited insights into the process of population decline and extinction. Moreover there is still little appreciation of how local processes scale up to global patterns.

A recent paper published by scientists from the Zoological Society of London (ZSL), the University of Cambridge, Yale University and the WWF presents a new model for predicting extinction, utilizing the Living Planet Index . The model aims to predict species extinctions based upon the analysis of LPI population trends and the Pantheria database on mammal traits.

This could provide conservationists with a tool for predicting species extiction patterns which, may go a way to developing a more preventative approach to targeting species conservation efforts. "We hope that our work goes some way to providing the information needed to prescribe ways to counteract wildlife declines" says Dr Ben Collen.

A grain of hope in the desert (16th June 2011)

The latest update of the IUCN Red List of Threatened Species shows that while many species continue to decline, it is not a losing battle. Captive breeding and re-introduction efforts have allowed the Arabian oryx - hunted to near extinction in the 1970s - to be moved from the Endangered category to Vulnerable.

"We need to continue to learn from the success stories, scaling them up to more species, over greater areas and improve the odds for wildlife still on the brink of extinction", says Dr Ben Collen.

Evolution Lost: Global wildlife stocktake (27th October 2010)

The most comprehensive stocktake of the world’s vertebrates reveals that populations of mammal, bird, reptile, amphibian and fish species have declined on average by 30 per cent over 40 years, and one fifth of all vertebrates species are threatened with extinction.

Evolution Lost, produced by the Zoological Society of London (ZSL), uses the latest IUCN Red List of Threatened Species data and the WWF Living Planet Index population data to give us a complete picture of the state of the world’s vertebrates.

Over the past four decades terrestrial mammal populations are estimated to have declined by a quarter, marine fish by a fifth and freshwater fish by as much as 65%.

In addition to providing a baseline for the health of vertebrates, Evolution Lost also highlights the unique evolutionary history that we have lost through past species extinctions. The Guam flying fox, Las Vegas valley leopard frog and the Cape Verde giant skink are just some of the of the species no longer stalking our planet today.

The new IUCN Red List of Threatened Species data in Evolution Lost will also be published in a paper in the international journal Science, which will highlight that biodiversity would have declined by an additional 20 per cent if conservation processes had not been in place.

Severe declines in tropical species abundance as natural resources are exhausted at an alarming rate – WWF 2010 Living Planet Report (13th October 2010)

The 2010 edition of WWF’s Living Planet Report – the leading survey of the planet’s health – shows populations of tropical species are plummeting and humanity’s demands on natural resources are sky-rocketing to 50 per cent more than the earth can sustain. The biennial report, produced in collaboration with the Zoological Society of London and the Global Footprint Network, uses the global Living Planet Index as a measure of the health of almost 8,000 populations of more than 2,500 species. The global Index shows a decrease by 30 per cent since 1970, with the tropics hardest hit showing a 60 per cent decline in less than 40 years.

Significant declines in African freshwater species, pose major threat to availability of resources (2nd September, 2010).

In a report published today by the IUCN, it was found that 21% of African freshwater species are threatened with extinction. The study was based on regional conservation assessments of 5,167 species of freshwater fish, molluscs, crabs, dragonflies and damselflies, and selected aquatic plants, some of which were assessed as part of the Sampled Red List Index (SRLI) project.

Large mammal population declines in Africa’s protected areas (12th July, 2010)

A multi-species index based on nearly 600 population time series from 78 African Protected Areas points to a 59% decline in large mammal abundance between 1970 and 2005. While this suggests that African PAs have failed to mitigate human-induced threats to large mammal populations, “the situation outside the parks is almost undoubtedly worse”, says lead author Ian Craigie. In addition, increasing trends at a regional level demonstrate that protected areas can be effective if properly managed.

World governments fail to deliver on 2010 biodiversity targets (5th May, 2010)

World leaders have failed to deliver commitments made in 2002 to reduce the global rate of biodiversity loss by 2010, finds a new study published in the leading journal Science. "Biodiversity is still being lost as fast as ever, and we have made little headway in reducing the pressures on species, habitats and ecosystems." said Dr Stuart Butchard, the paper’s lead author.

High Arctic species on thin ice (17th March, 2010)

An assessment of the Arctic’s biodiversity reports a 26 per cent decline in species populations in the high Arctic. “Rapid changes to the Arctic’s ecosystems will have consequences for the Arctic that will be felt globally” says lead-author Louise McRae from ZSL. In contrast, population levels of species living in the sub Arctic and low Arctic are relatively stable or increasing.

Efforts to sustain biodiversity fall short (19th November 2009)

With nations admitting that they will fail to achieve their goal of significantly cutting biodiversity loss by 2010, a flurry of work is under way to develop new, more robust targets and ways of monitoring progress. "The indicators we have at the moment will slot into the new framework, but new ones will also have to be developed", Dr Ben Collen, ZSL.

Convention on Migratory Species (December 2008)

Animal migrations provide some of the most spell binding images in the natural world. Through the United Nations body charged with protecting migratory species - the Convention on Migratory Species - we are monitoring populations of migratory species.

The final report shows mixed prospects for migratory species.

2008 Living Planet Report (29th October 2008)

The 2008 Living Planet report shows that over a time period when human population has almost doubled, animal populations have declined by around 30%. Direct anthropogenic threats to biodiversity result from habitat loss (especially due to agriculture), overexploitation of species (especially due to fishing and hunting, pollution, the spread of invasive species or genes and climate change).

Mammals under threat (6th October 2008)

The Red List shows that one in four mammal species are at risk of extinction, with habitat loss, hunting, climate change and disease being the main threats mammals are facing. At least 188 mammals were assessed as Critically Endangered, 29 of which may already be extinct (such as the Yangtze River Dolphin).

Reptile loss threatens global biodiversity (6th October 2008)

The SRLI reveals that more than a fifth of the world's reptiles are threatened with extinction. Dr Jonathan Baillie (ZSL) describes the SRLI as "a quantum leap forward in our understanding of biodiversity. The disadvantage is you can't look at all individual species, but to address the bigger problems we have to understand things at an ecosystem, or habitat, level".
