‘An exciting moment': England's urban and rural trees mapped for first time
England's non-woodland trees have been mapped for the first time, using cutting-edge methods of laser detection and satellite imagery.
Tree scientists at the UK's Forest Research agency have built a comprehensive picture of trees in urban and rural areas in a 'groundbreaking' map that goes live on Saturday.
The tool will allow conservation groups and local authorities to target tree-planting efforts more accurately by pinpointing lone trees that could be connected to nearby wooded areas, bolstering habitats for wildlife, they said.
The environment department, Defra, said this would support the government's pledge to expand nature-rich habitats and help to achieve its legally binding target to increase England's woodland canopy to 16.5% of total land area by 2050.
The forestry minister, Mary Creagh, said: 'Our precious street trees improve air quality, mark the changing seasons and provide us with peace, shade and joy. Their value simply cannot be overstated.
'This groundbreaking new tree census will not only help us better understand our current tree canopy cover, but allow us to identify areas where we can create more nature-rich habitats for wildlife and people to enjoy as part of our plan for change.'
Sir William Worsley, the chair of the Forestry Commission, said: 'This has been a real endeavour by the team – the results are spectacular and will be invaluable to us as we strive to meet our legal target to increase tree-planting cover.
'The map fills critical data gaps about our national tree assets, helping us understand this natural resource and the benefits it brings, including carbon storage. Many people – from citizens to governments – will use the map to make evidence-based decisions to improve management and protection of our trees.'
Freddie Hunter, the head of remote sensing at Forest Research, said: 'This is an exciting moment. By using the latest technology, we have been able to pinpoint all tree cover across England, including trees outside of woodland for the first time.
'This laser technology measures the Earth's surface using satellite imagery, which we can use to capture tree canopy cover form a comprehensive picture across the breadth of the country and will be vital in informing future tree-planting'.
The maps shows single trees make up 30% of England's tree cover. They could play an important role in storing carbon, regulating temperatures and mitigating against climate change impacts, such as flooding and overheating in towns and cities, Defra said.
The trees can also help to improve health and wellbeing in urban areas by boosting nature and reducing the impacts of air pollution.
The map, which is fully automated and can be updated regularly to capture changes in tree canopy cover, was funded by Defra's natural capital and ecosystem assessment (NCEA) programme.
It comes as part of wider government efforts to boost woodlands, including recent announcements of a new national forest, increasing timber in construction to boost forestry and sustainable housebuilding and a dedicated tree-planting taskforce.

Zoo animals to get more space in ‘long-overdue' welfare reforms
The Department for Environment Food & Rural Affairs (Defra) said new standards published on Saturday would modernise British zoo practices for the first time in over a decade, better protecting species ranging from 'the majestic snowy owl and golden eagle' to 'iconic elephants' and 'wonders of the sea like sting rays and octopus'.

Map shows 80% of England's peatlands dry and degraded
New mapping data has shown 80% of England's peatlands to be dry and damaged. The government said the findings, shown on an open source map, presented a worrying picture, with degraded peat emitting carbon into the atmosphere and contributing to global peat is the country's biggest carbon store but when damaged it releases planet-warming greenhouse gases into the the most extensive peatland habitat was shown to be found across parts of the Lake District, the Pennines, North York Moors and in the uplands of the south-west of England. Scientists have used satellite imagery, artificial intelligence and in-depth data analysis to create the most complete map of England's peatland and peaty soils to date, the Department for Environment, Food and Rural Affairs (Defra) vital carbon sinks, healthy peatlands can help tackle climate change, reduce flood risk, improve water quality and support rare wildlife, including the golden plover, curlews and 25 species of dragonflies. The map models the extent, depth and important aspects of the condition of England's peat, including vegetation, gullies and man-made as well as natural draining found that peaty soil covers roughly 8.5% of England's surface with four-fifths of England's peatlands also revealed to be in a dry and degraded map showed that three-quarters of the surface was shown to be covered by plants and land use types associated with dryer conditions such as heather, while only 1% is covered by important peat-forming plants such as sphagnum Wildlife Trust said it was looking to restore some of its peatlands, which were historically burned to help heat homes last in Dartmoor, the University of Exeter estimates just 1% of its deep peat is healthy, peat-forming to restore this vital natural resource are under way, including in Exmoor, Dartmoor and Cornwall, but scientists are warning climate change could make that difficult.

Eighty percent of England's peatlands are dry and degraded, mapping shows
New mapping of England's peatlands has revealed that 80% of the habitats are dry and degraded. Scientists mapped England's peatlands and peaty soils for the first time using satellite imagery, artificial intelligence and in-depth data analysis to create the most complete map to date, the Department for Environment, Food and Rural Affairs (Defra) said. The open source map, launched on the government's website on Monday, models the extent, depth and condition of England's peat, encompassing vegetation, gullies and human-made and natural draining channels. Healthy peatlands can help to tackle the climate crisis, reduce flood risk, improve water quality and support rare wildlife including the golden plover, curlews and 25 species of dragonflies. However, degraded peat means carbon is emitted into the atmosphere, contributing to global heating. The map found that peaty soil covers roughly 8.5% of England's surface, with the most extensive peatland habitats in the Pennines, North York Moors, parts of the Lake District and the uplands of the south-west. However, the research also found that 80% of England's peatlands were in a dry and degraded condition. The map showed that while three-quarters of the peatlands are covered by plants and land use types associated with dryer conditions, only 1% were covered by important peat-forming plants such as sphagnum moss. Dr Sallie Bailey, Natural England's chief scientist, said: 'Trying to map something that's largely underground, changes in volume depending on whether it's rained recently and tries to swallow you up every time you set foot in it comes with its challenges, which makes this map extraordinary in its accomplishment and something of a global first. 'Mapping peat to this level of detail will help us maximise the benefits of peat and massively advances our understanding of the role our peatlands are playing in a changing climate.' Defra has said understanding how much peat England has is the first step to calculating how much carbon it holds and how much it is releasing. Ministers also hope that land managers will use the map to better understand and restore peatland, through measures such as blocking drainage channels to re-wet the land, and that it will help decision-makers in balancing biodiversity and carbon storage with food security. Tony Juniper, the chair of Natural England, said: 'The benefits of healthy peatlands are well documented. They are our biggest natural carbon stores, essential to the water cycle and refuge to some of our rarest plants and wildlife, such as the carnivorous sundew plant, marsh violet, and charismatic birds like golden plover and curlew. 'The England peat map will allow us to make far better and more informed decisions when it comes to managing peatlands – targeting restoration efforts to the most degraded peat and identifying the best opportunities for nature recovery.' Caroline Thorogood, the National Trust's lead for peatlands, said: 'The data in the map will help us take a significant step forward to more accurately map peatlands that we own and care for in England and understand their condition. 'This will allow us to better identify priorities and action future work to recover our precious peatlands, helping nature thrive and providing benefits such as carbon storage and water regulation.'
