The organisations have signed a Memorandum of Understanding, committing to share knowledge and experience. The aim is to develop skills and business support for the environmental conservation sector, including training, information, advice and funding.
BTCV training development manager David Ashurst said: "BTCV is recognised as a natural partner in helping to ensure that support for skills development reflects needs and is increasingly demand-led."
Lantra industry partnership manager Kevin Patrick said: "Lantra and BTCV share a number of strategic and business objectives relating to the development of people, both employed and volunteers, in environmental conservation."
The partnership has been established through research on volunteer skills, which found 500,000 people volunteer in the environmental and land-based industries.
