The particularly in wood pasture and veteran tree next 10 years are a bridge between the Act (1878) which sets out the City’s duty to management, conservation grazing and substantial heathland, mire and wood protect and conserve Burnham Beeches for heathland restoration. They influence, and public recreation and wildlife conservation pasture restoration of previous plans and are influenced by, countryside management ‘in perpetuity’. It is further safeguarded by the development of on-going management practice across the country and Europe. national and international legislation. practices to maintain these valuable Each project is meticulously planned and researched to ensure it provides maximum habitats in good condition.

Aspects of the management plan were presented in a public consultation exercise in October 2019 attended by over 900 people. All aspects of the plan received a high level of support. Our special thanks are extended to all those who helped to influence and produce this document.
Things we learnt in the last 10 years w Several species of lichen, beetles, flies and moths new to the Beeches have been found, demonstrating the astonishing diversity of the nature reserve. w The Main and Little Commons have some unexpectedly rare and interesting plants on them. w Burnham Beeches was designated a Nationally Important Fungus Area and Important Plant Area. w The nature reserve continues to be a stronghold for the rare moss, Zygodon forsteri. w Burnham Beeches has more visitors per hectare than other sites of the same conservation status in the UK. w Soils in areas with higher visitor pressure are richer in bacteria and poorer in fungi, indicating a decline in soil health. w We have a better understanding of where our visitors come from and where they walk on the Beeches. w DCOs/PSPOs have been highly effective and have significantly reduced anti-social behaviour on the reserve. w Water catchments of the streams that flow into the Beeches have been clearly identified and mapped. Burnham Beeches offers a unique mixture of habitats and wildlife. Careful management is needed to meet the needs of both recreation and conservation. 5 DRAFT INTRODUCTION

Many studies have shown that low density of grazing is beneficial to the majority of animals and plants that occur in woodland.

Grazing by domestic livestock is essential to keep heathland in good condition and stop it reverting to woodland again.

This variation helps animals too. Invertebrates have many different needs, such as open areas to bask in or tall plants on which to build webs. Many species need more than one type of microhabitat in the course of their life, such as different places to feed and lay eggs in. Even vertebrates such as birds and reptiles need variation in order to thrive. A habitat with no structural variation, like a cereal field, may be good for a small number of species but it will not support the variety of a naturally varied Cattle grazing on LIttle Common, alongside the main habitat.

One example is the endangered Polietes steinii that is associated with traditional grazing on unimproved pastures and needs horse dung for the larvae to develop in.
