The Big Society initiative will see Braywick Nature Centre in Maidenhead taken over by a national environmental charity from April.
Outsourcing the management of the Royal Borough-owned centre, in Hibbert Road, will save the council £6,000 of taxpayer's money in running costs.
The council says its five-year partnership with the charity Groundwork Thames Valley (GTV) will provide better services and more volunteering opportunities at the centre.
New development manager Richard Pollard said: "We are looking forward to working in partnership with the Royal Borough to grow the services and volunteering opportunities that have already made Braywick a unique and successful Big Society hub."
There are plans for a new cafe, to be staffed mainly by volunteers, and increased opportunities for schools to get involved, as well as a new education programme.
The savings began last year when senior countryside ranger Trevor Smith, who had worked at the centre since the Eighties, was made redundant.
The remaining ranger, employed by the Royal Borough, will remain at the centre to help encourage volunteering and charitable contributions.
The partnership was agreed by cabinet in December.
