CONSERVING NATURE IN LONDON
Many plants and animals have adapted to live alongside man in London. This talk explores the interface between humans and wildlife and how our urban environment may best be managed for the benefit of both.
THE NATURAL HISTORY OF THE GARDEN
Gardeners soon become aware that they do not have “vacant possession”. A great variety of wildlife co-exists within the garden. This talk describes some of the complex interrelationships of the plants and animals which live in our gardens.
GARDENING FOR WILDLIFE

WILD FLOWERS IN THE GARDEN
This talk describes the wide variety of native wild flowers which may be grown in the garden. Many of our wild flowers are under threat in the countryside as their natural habitats are disappearing. By providing a sanctuary within the garden we can help to conserve some of our most attractive and endangered species. The relationship between native plants and the wildlife that depends upon them is discussed and illustrated. This talk includes a discussion concerning- the thorny problem of “weeds” and how to deal with them.

THE NATURAL HISTORY OF HARINGEY’S ANCIENT WOODLANDS
Haringey in North London is most fortunate in possessing no less than four ancient woodlands. Their rich and varied natural histories are examined in relation to differences in their past management. Recent changes following a renewal of coppicing are discussed. These woods support a rich bird life which includes all three British species of woodpecker, and hawfinches are known to breed in at least one of them.
THE NATURAL HISTORY OF THE NEW RIVER
London’s New River is an historic water course which has been bringing fresh water from Hertfordshire to Inner London for nearly 400 years. It is a priceless green asset, rich in plants, birds and animal life. This talk examines the natural history of the New River and its associated reservoirs and filter beds. Together they support a remarkable range of wildlife, which includes rare plants and unusual water birds.
WILDLIFE AT CHRISTMAS
What range of plants and animals can we expect to see at Christmas? What strategies have they evolved for survival in the depth of the winter?
