New measures needed to help struggling wildlife cope with water shortages

New measures needed to help struggling wildlife cope with water shortages

The Wildlife Trusts call for efficient water management, huge reductions in pollution, and support for landowners to create more space for nature

The driest weeks for parts of England since 1935 have left nature under pressure with wildfires devastating landscapes, habitats left parched, and wildlife endangered by concentrated levels of pollutants in low-flowing rivers.

The Wildlife Trusts are extremely concerned about the impacts on natural areas – in particular, on rivers, wetlands, and streams – and are calling on the Government to introduce a suite of measures:

  • Set a fixed target under the Environment Act for reducing water use, and require the installation of meters to ensure there is enough water in rivers for nature and society
  • Ensure that developers, farmers, and water firms significantly reduce pollution by:
    • Investigating and penalising water companies for illegal discharges of sewage
    • Enforcing rules to protect rivers from agricultural pollution
    • Ensuring that new building developments help to reduce pollution, rather than only being required not to make things worse
  • Bring forward ambitious farming support schemes that reduce water pollution from fertilisers and pesticides, tackle soil erosion, and restore hedgerows and wetlands
  • Set out specific objectives to help nature cope with drought, fire, and flooding in the next set of UK national climate adaptation programmes
  • Reinstate climate change adaptation support services for land managers, including funding to help regulate water flows to cope with floods and drought

 

Ali Morse, water policy manager for The Wildlife Trusts, says:

“Nature is really struggling with extreme weather, and we need to act now to ensure our parched landscapes and rivers – the natural environment that provides us with food and water – are more resilient in the future. It is critical to create more space for nature to keep land from drying out and give support to landowners for projects, such as beaver releases, that help ecosystems to recover.

“Water bosses should unite and impose a country-wide hosepipe ban to reduce non-essential use and avoid the worst impacts of drought on rivers and wildlife, rather than relying on more damaging measures later. Water companies must also invest in water storage infrastructure, tackle leaks, and improve water efficiency – it’s a scandal that so much water is wasted every day. Government must ensure that new homes are water-efficient and bring in universal water metering to help all customers limit their water use.”

 

Vast quantities of water are used and leaked every day

  • Every day in England, 14,000,000,000 (fourteen billion) litres of water are taken from the environment and put into supply by water companies. That’s equivalent to taking all the water that flows past Teddington on the River Thames each day, three times over.
  • Almost 2,400 million litres of the water abstracted (extracted for people to use) is lost to leakage every day. Around a fifth is used to supply non-household premises  (businesses, schools, industry) and the remainder is used to supply domestic customers.

 

The Wildlife Trusts believe more action is needed to tackle leaks, and that water companies should help businesses and householders to waste less. Water companies should also improve capacity to store water when it is plentiful so that less is extracted from rivers – particularly in times of drought when nature needs it most.

No rain makes a bad situation worse for wildlife

The Wildlife Trusts have reported on the impacts of drought, wildfires and extreme temperatures on nature reserves and wildlife across the UK. They include:

  • Peatlands in some areas are exceptionally dry, which is bad for nature and climate as dry peat is much more prone to wildfire and emits more carbon when degraded
  • Sphagnum moss that covers peat is turning white instead of green in many places. Lots of birds, mammals and insects rely on the mosses being wet
  • Wildfires have broken out in recent weeks at nature reserves across the UK. They include a 650-hectare fire at Pirbright Ranges in Surrey, several hectares of damage at Gutteridge Woods, London, and a fire at Toby's Hill in Lincolnshire that damaged valuable sand dunes
  • Ponds, scrapes, and streams are drying up, forcing dragonflies and other insects into smaller bodies of water, which can affect their reproductive potential for next year
  • Chalk streams are very low across Hertfordshire and other parts of southern England. These internationally important habitats support all kinds of species including otters, water voles and kingfisher
  • Extended periods of low rainfall are expected to affect the availability of food for wildlife later in the year, with many plants having matured and fruited early
  • Mammals are struggling for food – for example badgers can’t reach earthworms, one of their staple foods, which have gone deeper in the earth to find moisture
  • Soil invertebrates and detritivores that recycle organic matter are being driven deeper into the soil, which can contribute to soil erosion in exposed places

 

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

 

Kathryn Brown, director of climate change and evidence at The Wildlife Trusts, says: 

“It is vital that Government prevents the irreversible degradation of nature and consequences for food and water security by protecting at least 30% of land and sea for nature by 2030. 

“Our recent report, Changing Nature, concluded that an enormous effort is needed to create more space for nature everywhere to enable natural ecosystems to function properly, create habitats for wildlife, and build diversity and flexibility for the future.”

Water wastage

A million litres, or a Megalitre, is equivalent to 1000 cubic meters. The flow of the Thames at Teddington is 53 cubic metres per second, or 4.5 million cubic meters (4.5 thousand Ml) a day. Water use in England is 14,000 Ml, or 3.05 times the flow of the Thames at the upper limit of the tideway, at Teddington.

 

The Wildlife Trusts & beavers

The Wildlife Trusts are at the forefront of beaver reintroductions in the UK and released a record number of beavers in 2021, with seventeen beavers released into fenced areas. 

Devon Wildlife Trust has been working with beavers for more than 10 years and led the River Otter Beaver Trial in 2015, England’s first wild beaver re-introduction project. The Trial represented one of the most comprehensive independent scientific studies of beavers and their impacts. Its evidence formed the basis of the Government’s decision that the Devon beavers should remain in the wild. Find out more about Devon's beavers here.

 

Climate adaptation

The Wildlife Trusts’ recent report, Changing Nature, found that extreme weather has already affected many Wildlife Trust reserves, including:

  • Recent 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
  • The current drought – has lowered the water table on wetland nature reserves, dried out chalk streams and peat bogs, and concentrated pollution in rivers

 

The Wildlife Trusts are 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.
