Birds benefiting from climate change may find boost is short-lived. And more news from North America

From Rare Bird Alert

Climate change is a major global threat to humanity and nature. It threatens to undermine our water and food supplies, it’s fueling extreme weather and some mega-cities are predicted to disappear under rising sea levels.

So conservationists were flummoxed by studies which showed climate change is having a stronger effect upon species which benefit from climate change compared to those which suffer negative impacts.

The authors of a major study investigating 525 bird species over 30 years and across two continents believed there could be a time lag in the response of populations to climate change, creating an ‘extinction debt’. They were also concerned most studies cover time spans too short to pick up on shrinking habitat ranges and focused on changes in range, rather than change in numbers.

But the most detailed report of its kind to date has turned theories about the effects of climate change upon birds on their head.

Despite carefully examining the population trends of over 500 bird species over three decades, the researchers found no evidence climate change has a more profound effect upon birds which should cope well with climate change compared to those which might struggle. Climate change is causing widespread population change in birds.

The researchers called for further research into the long-term consequences of climate change on wildlife to be commissioned urgently.

Earlier this month a landmark paper in Science (read about it here) suggested the loss of nearly 3 billion birds in North America over the last fifty years linked to a range of factors, such as habitat loss and intensive agriculture, were all exacerbated by climate change. The new study, led by the RSPB, goes even further and argues climate change may be a major driver of population change in birds, aggravated by other factors.

Head of Species Monitoring and Research, Conservation Science at the RSPB, Prof. Richard Gregory said: “Our precious wildlife is already struggling to cope with habitat destruction, farming practices, pollution, harmful fishing and invasive non-native species humans have introduced into fragile eco-systems.

“The climate crisis and biodiversity crisis are two sides of the same coin and need to be tackled together.

Scientists from around Europe contributed to the report, which was led by the RSPB.

There is further alarming news from North America where Audubon scientists took advantage of 140 million observations, recorded by birders and scientists, to describe where 604 North American bird species live today. They then used the latest climate models to project how each species’ range will shift as climate change and other human impacts advance across the continent.

The results are clear: Birds will be forced to relocate to find favourable homes. And they may not survive. Read their report Survival by Degrees: 389 Bird Species on the Brink here

October volunteer activity

Sunday 13th October 2019 – Victoria Tower, St Martin – 10:30-13.00

From Jersey Conservation Volunteers

Task The grassland at Victoria Tower is managed with an annual late-season cut, with patches of uncut vegetation left for overwintering invertebrates in different parts of the site from year to year. This task will primarily involve raking up and clearing cuttings, although we may also undertake a small amount of sensitive scrub management and self-seeded sycamore control if time allows. We will work with the National Trust for Jersey.

If you have any questions, or if you wish to be added to the Jersey Conservation Volunteers email list, please contact either Julia Clively (tel: 441600; j.clively@gov.je) or Jon Parkes (tel: 483193; jon.parkes@nationaltrust.je).

The site Victoria Tower, St Martin. We will meet in the car park at the end of Le Mont Mallet (Jersey phone directory map Map 11, MM15) Google maps here

Parking Parking at the site is very limited but further on road parking is available along La Rue de La Pouclee et des Quatre Chemins. Please also consider car sharing or cycling.

Please meet at 10:20 for a 10:30 start and we will be finished by 13.00.

Tools needed As always, tools will be provided but if you have a pair of gardening gloves, a rake, fork or cutting tools (e.g. pruning saw, loppers, secateurs) it would be helpful if you could bring them along with you.

Clothing needed Please check the weather forecast and wear suitable clothing.

Children All are welcome, young or old although we do ask that volunteers under 16 years of age are accompanied by an adult.

Refreshments We will be treated to Kim’s latest batch of delicious cakes, washed down with a nice cup of tea or coffee.

No let-up in loss of UK’s nature

The UK’s wildlife continues to decline according to the State of Nature 2019 report. The latest findings show that since rigorous scientific monitoring began in the 1970s there has been a 13% decline in average abundance across wildlife studied and that the declines continue unabated.

Following the State of Nature reports in 2013 and 2016, leading professionals from more than 70 wildlife organisations have joined with government agencies for the first time, to present the clearest picture to date of the status of our species across land and sea.

The State of Nature 2019 report also reveals that 41% of UK species studied have declined, 26% have increased and 33% shown little change since 1970, while 133 species assessed have already been lost from our shores since 1500. 

Butterflies and moths have been particularly hard hit with numbers of butterflies down by 17% and moths down by 25%. The numbers of species, such as the high brown fritillary and grayling, that require more specialised habitats have declined by more than three quarters.

The UK’s mammals also fare badly with greater than 26% of species at risk of disappearing altogether. The wild cat and greater mouse-eared bat are among those species teetering on the edge of disappearing.

Much is known about the causes of decline and about some of the ways in which we could reduce impacts and help struggling species. The evidence from the last 50 years shows that significant and ongoing changes in the way we manage our land for agriculture, and the ongoing effects of climate change are having the biggest impacts on nature.

Pollution is also a major issue. Whilst emissions of many pollutants have been reduced dramatically in recent decades, pollution continues to have a severe impact on the UK’s sensitive habitats and freshwaters, and new pollutant threats are continuing to emerge.

Daniel Hayhow, lead author on the report, said: “We know more about the UK’s wildlife than any other country on the planet, and what it is telling us should make us sit up and listen. We need to respond more urgently across the board if we are to put nature back where it belongs. Governments, conservation groups and individuals must continue to work together to help restore our land and sea for wildlife and people in a way that is both ambitious and inspiring for future generations”

“In this report we have drawn on the best available data on the UK’s biodiversity, produced by partnerships between conservation NGOs, research institutes, UK and national governments, and thousands of dedicated volunteers. It’s through working together that we can help nature recover but the battle must intensify.”

Whilst the data that the report shows are alarming there is also cause for some cautious hope. The report showcases a wide range of exciting conservation initiatives, with partnerships delivering inspiring results for some of the UK’s nature. Species such as bitterns and large blue butterfly have been saved through the concerted efforts of organisations and individuals.

Reflecting growing concern about the environmental and climate emergencies, public support for conservation also continues to grow, with NGO expenditure up by 26% since 2010/11 and time donated by volunteers having increased by 40% since 2000. However, public sector expenditure on biodiversity in the UK, as a proportion of GDP, has fallen by 42% since a peak in 2008/09.

The report has a foreword by a collective of young conservationists who are passionate about conservation and the future of our wildlife and nature to preserve it for future generations.

Dan Rouse, a young conservationist said, “Nature is something that shaped my childhood, that allowed me to be free to use my sense of wonder, and to gain an insight into the wonderful world of nature! It’s young people that are now picking up the baton to save our nature – we’ve already lost Corn Buntings and Nightingales in Wales – how long until they’re gone from the rest of the UK? Along with the eerie calls of curlew and the gentle purr of the turtle doves.”

Sophie Pavelle, a young conservationist said “What a huge wake-up call 2019 has been! I have felt the loss of nature more acutely this year than any other. A dawn chorus less deafening, hedgerows less frantic, bizarre, worrying weather…it seems that in a more complex world nature is tired, muted and confused. People protect what they love, and if we can find quirky, empowering ways to encourage young people to connect with nature emotionally and see it as something they can truly champion – only then can we dig deep to find real hope for a brighter, sustained future for our natural world.”

Locally, partners in the report include Channel Islands representatives (see the list below) and Guernsey’s Andy McCutcheon, Principal Environment Services Officer, Agriculture, Countryside & Land Management Services (ACLMS) “Guernsey welcomes the opportunity to be part of the State of Nature report.  The report paints a picture which should concern everyone. We have had a Biodiversity Strategy in place for nearly four years and this report forces us to face facts. It is only by understanding what we are losing and how we are losing it that we can begin to reverse the serious decline in our species rich habitats such as unimproved grassland.”
