It is very important for Jersey to keep its connection with the past, the president of the National Trust for Jersey has said.
Mike Stentiford said the trust is facing huge challenges and as a result is putting its membership fees up by £5 in 2010.
He said he regrets the increase but was left with no choice.
The money will be used to preserve Jersey's landscape, heritage and culture for the future, he said.
"If we start loosing that connection with the past and getting a disinterest in it then we'll be a very sad little island," Mr Stentiford said.
The days of generous bequests to the trust appear to be sadly distant, Mr Stentiford told BBC Jersey.
The fees will go up from 1 January.
The Jersey branch of the National Trust was set up in the 1930s to preserve sites of historic and natural interest.
It owns woodland, farmland, heathland and meadows as well as a number of historic buildings.
