People's Trust for Endangered Species
Peoples Trust for Endangered Species (PTES) is a UK-based charitable organisation registered in England and Wales. Founded in 1977, PTES works on the frontlines of conservation by supporting vital projects that address the threats faced by species at risk of extinction globally. Through a combination of scientific research, monitoring, education, habitat restoration and public engagement, the organisation seeks to ensure that endangered species not only survive but thrive. It also owns and manages two nature reserves. PTES collaborates with local communities, governments, and conservation organisations worldwide to create lasting solutions for the preservation of biodiversity. With a focus on both iconic species and lesser-known wildlife, PTES is committed to ensuring these animals thrive in the future.[1] As of January 2025, PTES has 20 employees, five trustees and coordinates around 50,000 volunteers in the UK[2]. PTES relies on donations from the general public and grants from trusts and foundations to continue its work - it receives no core funding from the UK Government. The organisation has registered charity number 274206. HistoryPTES was founded in 1977. Originally based in South Kensington at Imperial College London, PTES moved to its present location in Battersea, south-west London in 1993. In 2001 PTES developed Mammals Trust UK, a restricted fund and campaign targeting the conservation of British mammals. In 2006, Mammals Trust UK was incorporated under the activities of PTES. PTES still operates a ring-fenced funding stream for British mammals but the names ‘Mammals Trust UK’ and 'Mammals Trust' have since been disbanded. ActivitiesPTES exists to support and restore natural heritage – the diverse assemblages of species and their habitats – through practical conservation and by educating and informing people about its importance. The charity supports conservation projects and research both in the UK and abroad through three funding schemes: 'Conservation Insight Grants’, ‘UK mammal grants’ and ‘Conservation Internship Awards’.[3] The charity's work in the UK has a focus on mammals, with hazel dormice, European hedgehogs and European water voles as the current key species. Saproxylic beetles are also a key group. Traditional orchards, wood pasture and parkland, and hedgerows are key habitats[4]. Assistance from volunteers and collaboration with other environmental organisations are integral to this work. Wildlife SurveysPTES runs several national, public-participation surveys aimed at monitoring wild populations and habitats. As of 2025, extant surveys are:
CampaignsIn 2011, in partnership with wildlife charity the British Hedgehog Preservation Society (BHPS), PTES launched the campaign 'Hedgehog Street’ in response to a detected decline in Britain’s hedgehog (Erinaceus europaeus) population. As of 2025, the campaign has more than 130,000 registered volunteers called ‘Hedgehog Champions’ who are committed to making changes in their gardens to encourage and support hedgehogs. The Hedgehog Street website provides volunteers with information about the ecology and behaviour of hedgehogs, tips on ways of managing gardens to benefit them, and free resources to encourage volunteers to recruit other people to participate[6]. One of the major objectives of the campaign is to work with the public and housing developers to connect gardens and greenspaces with 'Hedgehog Highways', which are 13cm x 13cm square holes in fences/boundaries that allow hedgehogs to travel further to find food and nesting sites. As part of the joint campaign, PTES coordinates the European Hedgehog Research Group and convenes a steering group for the species, based on the previous BAP group, that includes the British Hedgehog Preservation Society (BHPS), mammal ecologist Dr Pat Morris, and hedgehog enthusiast and author Hugh Warwick. In 2025 they produced the first conservation strategy for the species in the UK. The only UK training course on hedgehog-friendly land management, surveying and mitigation for professionals has also been developed and is being delivered around the UK. PTES also supports research into the causes of hedgehog decline. Some of this is jointly funded with BHPS. ReservesPTES own and manage 158 hectares of land on the Isle of Wight, including a majority of the Briddlesford Copses Site of Special Scientific Interest (SSSI) and Special Area of Conservation (SAC) together with about 50 hectares of farmland. The Briddlesford Copses represent the largest remaining block of ancient semi-natural woodland on the Isle of Wight. Notable species present include Hazel dormouse, Bechstein’s bat, barbastelle bat, red squirrel, narrow-leaved lungwort and the fungus weevil Pseudeuparius sepicola. Rough Hill is a traditionally managed orchard of ~4 hectares, located on a bank of the river Avon on the outskirts of Pershore, Worcestershire. Since being acquired by the Trust in 2003, the orchard is being sensitively restored for the benefit of its biodiversity and heritage value. The principal management activities are the provision and care of new fruit trees, restoration pruning of extant mature trees, and the use of extensive livestock grazing to manage the species-rich calcareous grassland communities present. Associate organisationsPTES is a member of the IUCN and Wildlife and Countryside Link.[7] PTES is also one of the original organisations in the State of Nature partnership[8].
