Northumberland Wildlife Trust is inviting the public to consider leaving a legacy to support wildlife during the Remember A Charity Week.
The campaign, which takes place from September 9 to 15, aims to highlight the significant role that legacies play in funding charities.
Predominantly known as Wilanthropy, such gifts raise £4 billion annually for good causes across the UK.
Northumberland Wildlife Trust's chief executive, Mike Pratt, said: "Making a gift to us when a person writes or updates their Will is a very special way of ensuring we can continue to undertake our work on our 60+ reserves.
"A donation will mean a new nature reserve can be purchased, a rare habitat secured or that people who have the skills and passion to protect wildlife can continue to do this."
Without these legacies, many charities would struggle to continue.
Previous Willanthropy contributed to land purchases for new nature reserves and funding for provisions like paint for wildlife crafting.
This winter, the Trust plans to plant various trees on its Whitelee Moor reserve, in memory of a recently deceased nature enthusiast.
Mr Pratt said: "Let’s not forget how everybody turned to their local green spaces during the covid lockdowns, so why not give a little back to protect these areas?"
