A grant-making trust is preparing for a rush of applications from charities after announcing it is to spend all of its £35.5m endowment.
The Tubney Charitable Trust decided to distribute all of its funds following the death of its founder, Miles Blackwell. The Oxford book publisher and his wife Briony died within weeks of each other in 2001.
The trustees' strategic review has resulted in the decision to wind up the organisation, which employs four staff, over the next eight to 10 years.
The closure announcement means the trust, which has awarded £14m since 2001, will be able to distribute larger sums in its final years.
Under new funding guidelines, it will support applications for projects that conserve the UK's natural environment and initiatives that improve the welfare of farmed animals in the UK and abroad.
"The wishes of the trust's founders to spend out the charity's endowment in the near term, over an anticipated eight-to-10-year period, were central to decisions made during the review," said trust chairman Jonathan Birchfield.
He said priority would be given to "high-quality projects that will achieve a long-term impact to endure beyond the life of the trust".
The review also narrowed the funding remit: arts, education and palliative care will no longer be supported.
Executive director Sarah Ridley said the final grants would be made in the areas that mattered most to the Blackwells. "By spending out now we are able to make larger awards than if we were to continue just spending the interest on the endowment," she said.
The minimum award will be £30,000; no upper limit has been set. Visit www.tubney.org.uk for details.
