text: Activities Wildlife Trusts are local organisations of differing size, history and origins, and can vary greatly in their constitution, activities and membership. However, all Wildlife Trusts share a common interest in wildlife and biodiversity, rooted in a practical tradition of land management and conservation. Almost all Wildlife Trusts are significant landowners, with many nature reserves. Collectively they are the third largest voluntary sector landowners in the UK. They often have extensive educational activities, and programmes of public events and education. The Wildlife Trusts centrally and locally also lobby for better protection of the UK's natural heritage, by becoming involved in planning matters and by national campaigning through the Royal Society of Wildlife Trusts. The Trusts rely heavily upon volunteer labour for many of their activities, but nevertheless employ significant numbers of staff in countryside management and education. Thanks to their work promoting the personal and social development of young people, The Wildlife Trusts is a member of The National Council for Voluntary Youth Services (NCVYS).
  The Wildlife Trusts offer a Biodiversity Benchmark scheme through which companies can be assessed and recognised for their contribution to biodiversity. The assessment covers the organisation's performance under the headings of "Commitment, Planning, Implementation, and Monitoring and Review".
