London Natural History Society - The place for wildlife in London

No Events

The LNHS has suspended its indoor and outdoor events to follow the guidance of the UK Government which has introduced social distancing measures to reduce the spread of the Coronavirus (Covid-19). We will continue to monitor the situation and LNHS events will resume when this is compatible with the advice issued by the UK Government. We will publicise resumption of events using the LNHS social media channels (including email groups). Your patience is appreciated and we hope everyone will stay safe.
The Library will also remain closed until the Natural History Museum re-opens.




The LNHS events programme is one of the most varied and active of a natural history society. Its field and indoor meetings encourage the interaction of beginners and experienced naturalists. Indoor events usually consist of talks, slide shows or discussions. Outdoor events are field meetings or guided tours. Coach trips to well-known wildlife sites in the South and East of England are also organised.




There are some fantastic places for wildlife in the London area. More than 40% of London is green space or open water. As many as 2000 species of flowering plant have been found growing in the LNHS area. The tidal Thames supports 120 species of fish. Over 60 species of bird nest in central London. LNHS members have recorded 47 species of butterfly, 1173 moths and more than 270 kinds of spider around London. London's wetland areas support nationally important populations of many water birds. London has 38 Sites of Special Scientific Interest (SSSIs), two National Nature Reserves and 76 Local Nature Reserves.




The LNHS offers a superb learning experience, through our expert led walks, our evening talks, publications and well stocked library. We share a common love of London's natural world, a desire to learn more about it, and share our expertise. To this end we also offer online resources, like school packs for the classroom, articles of general and particular interest, and online media.




London's biodiversity faces new challenges from climate change and development pressure. You can contribute to the conservation of wildlife in the London area by helping to record the changing fortunes of the many species that live here. Together with our historic records, this information will help us to tackle the conservation issues of the future. Join us, learn new skills, and help us to make a difference.

This large London park lies on a ridge made up of sands and gravels deposited by rivers and shallow seas, above a bed of older London Clay that had been laid down when the area was a deep sea, and provides one of the highest points in London. People have been using the heath for centuries and this has, inevitably, shaped the it into the area it is today. Managed by the City of London, the site is a Site of Metropolitan Importance for Nature Conservation and contains a Site of Special Scientific Interest and contains a wealth of historical features (including the Kenwood House estate managed by English Heritage).

Today the heath is not only a key site for naturalists, but is host to cultural events, home to a wide range of sports facilities and a popular place for Londoners to socialise. Most of the heath falls within the London Borough of Camden, with the Hampstead Heath Extension within the London Borough of Barnet.

Natural History

Hampstead Heath c Keiron Derek Brown 5© Keiron Derek BrownThe heath is a mosaic of habitats, including woodland, scrub, grassland (including small areas of acid grassland), hedgerows, ponds and wetlands, as well as small areas of heathland which gives this green space its name. 

These habitats provide a home for a wide range of animals, plants and fungi. Several organisations (including LNHS) have played a part in recording the wildlife of the heath.  

There have been many studies of the flora and fauna of the heath by LNHS members since the Society was formed over 150 years ago; many of them published in the Society's journal The London Naturalist.

A regular series of meetings and investigations was started over 20 years ago with the Hampstead Heath Survey; a long-term project with the objective to record the status and changes to all forms of wildlife on the heath (covering over 300ha), and to allow members to share and coordinate their recording efforts. See the webpage for details of upcoming events.

Reptile Survey of Hampstead Heath (2008-2009): A survey was carried out by the London, Essex and Hertfordshire Amphibian and Reptile Trust (LEHART) for the City of London for reptile species (excluding terrapins) on Hampstead Heath. The survey found that grass snakes remain the only native reptile on the heath and made recommendations for their conservation.

Millennial Flora of Hampstead Heath (1997-2003): This LNHS initiative consisted of extensive and structured recording of the vascular plants (flowering plants and ferns) growing on Hampstead Heath, and the places where they were found.

Ancient Tree Survey (2002): Heath Hands undertook a detailed survey to record various aspects of the ancient trees on the Heath. 790 trees were surveyed in total, with many oaks over 200 years old. The survey helped improve the future management of the veteran trees and plan for succeeding generations of woodland.
