Protected animals and plants face growing risk from climate change, new survey shows.

THE risk of wildlifes and droughts at nature reserves is set to significantly increase over the next 30 years, a new report warns.

Rare animal and plant species which depend on fragile habitats such as dry heathland, which are maintained by charities like BBOWT, will also be increasingly threatened by extreme weather as a result of climate change.

The warnings come from a new report by The Wildlife Trusts, of which BBOWT is a member.

The Trusts, which collectively manage 400 square miles of land for nature, carried out their first ever climate change risk assessment, and published the results today in a report entitled Changing Nature.

The research finds that, by the 2050s, under a future warming trajectory that reaches 3°C warming by 2100:

· Half of The Wildlife Trusts’ nature reserves will have 30+ days of very high fire risk yearly
· Almost all reserves will see more than 1°C increase on hot summer days by 2050
· 55% of reserves will see nearby river flows drop by more than 30% during times of low flow

The report shows how extreme weather is already affecting many Wildlife Trust reserves, including:

· Wildfires – have destroyed valuable and rare habitats, affecting the availability of food for wildlife, and costing huge amounts of time and money
· Flooding – has impacted wildlife, damaged infrastructure, and increased river pollution
· Droughts – have lowered the water table on wetland nature reserves, dried out chalk streams and peat bogs, and concentrated pollution in rivers

Last year BBOWT published its own climate change action plan, which revealed that numerous species at local reserves are already being hit hard by the effects of climate change, including dormice, beech trees and numerous songbirds such as blue tits, great tits and pied flycatchers.

The Wildlife Trusts now want to see increased effort from governments, business, and other landowners on climate adaptation, including greater investment in nature-based solutions and a specific focus on resilience.

Kathryn Brown, director of climate change and evidence for The Wildlife Trusts, said:

“Climate change is contributing more and more to nature’s decline with devastating consequences for people and wildlife. We are already stepping-up our efforts to restore habitats so that they benefit wildlife and are better able to store carbon. Our report also shows the range of actions we are taking to help nature adapt to climate change and what’s needed in the future – from further rewetting of peatlands to backing community-led rewilding projects.

“The projected impact of climate change on our nature reserves is just the tip of the iceberg. We need people to join us in creating a new national vision for our landscapes because we can no longer focus only on restoring nature to a historical state; change is inevitable.

“A concerted effort is required to create more space for nature everywhere, enabling natural ecosystems to function properly, creating habitats for wildlife, and building diversity and flexibility for the future.”

The Wildlife Trusts are already providing innovative solutions to help wildlife on land and sea adapt to the changing climate.

Projects include beaver releases and re-bending rivers to regulate water flows, restoring peatlands to help them cope with hotter, drier conditions, and initiatives to control invasive species.

Examples of projects include:

· The Wildlife Trusts, collectively, are restoring over 40,000 hectares of peatland habitat, improving the resilience of landscapes to heat, drought, and fire. For example:
· Somerset Wildlife Trust is rewetting lowland peat at Honeygar Farm
· Lancashire Wildlife Trust is improving the carbon storage capacity of upland peat
· Shropshire Wildlife Trust is rewetting the Mosses, benefitting wildlife and climate
· Sheffield, Staffordshire, and Cornwall Wildlife Trusts are reducing risks of wildfire by creating fire breaks, digging fire ponds, and rewetting at-risk areas
· Norfolk Wildlife Trust is restoring a naturally functioning wetland at Hickling Broad
· London Wildlife Trust is restoring chalk grassland so insects can move across the area
· Hampshire & Isle of Wight Wildlife Trust is creating ‘ark sites’ as refuges for white-clawed crayfish to help them re-establish numbers away from areas exposed to crayfish plague
· Warwickshire Wildlife Trust is re-bending the river Sherbourne and creating new wetlands
· North Wales Wildlife Trust is restoring seagrass meadows to improve marine resilience
· Essex Wildlife Trust is restoring saltmarshes and coastal habitat in the Blackwater estuary
· Devon Wildlife Trust is reverting coastal farmland to mudflats, boosting flood buffers
· Ulster Wildlife is producing priority mapping to focus on inshore blue carbon restoration
· Sussex Wildlife Trust is using a beetle to control the spread of Australian swampweed
· Bedfordshire, Cambridgeshire & Northamptonshire Wildlife Trust is creating butterfly banks (small earth mounds), providing a variety of microclimates to benefit different species
