text: Encouraged by the growing number of Trusts, the SPNR began in 1957 to discuss the possibility of forming a national federation of Naturalists' Trusts. Kent Naturalists Trust was established in 1958 with SPNR being active in encouraging its formation. In the following year the SPNR established the County Naturalists' Committee, which organised the first national conference for Naturalists' Trusts at Skegness in 1960. By 1964, the number of Trusts had increased to 36 and the Society for the Promotion of Nature Reserves had changed its name to The Society for the Promotion of Nature Conservation. In recognition of the movement's growing importance, its name was changed to The Royal Society for Nature Conservation in 1981.
  The movement continued to develop throughout the 1970s, and, by the early 1980s, most of today's Trusts had been established. In 1980, the first urban Wildlife Trust (now the Wildlife Trust for Birmingham and the Black Country) was established in the West Midlands, rapidly followed by others in London, Bristol and Sheffield. This was a watershed for the movement that strengthened its focus on wildlife and people. It was during this period that some Trusts changed their names from Naturalist Societies to Trusts for Nature Conservation. In 2002 the group changed their name to The Royal Society of Wildlife Trusts. The badger logo was adopted by the movement to establish its common identity. Also in 2002, the newest wildlife trust was formed, in Alderney.
