The Volunteer and Farmer Alliance is organised by the RSPB and offers farmers a free survey of the breeding birds on their land, carried out by a local volunteer.
Sarah Dullage is running the project in Northumberland and is inviting the county's farmers to take part in the new scheme.
She said: "Helping countryside birds such as lapwings, skylarks and tree sparrows can be surprisingly easy, but the vital first step is to identify what wildlife is already present on the farm.
"The Volunteer and Farmer Alliance initiative offers a free, no-strings-attached bird survey which saves farmers money and is a great way to identify and then start helping the birds on the farm."
The results of the survey are plotted on a unique 'bird map' that farmers can use to help boost local wildlife.
The information on these bird hotspot maps can also help bring in new income, as the wildlife data can be used in applications for agri-environment grants such as the Government's Higher Level Scheme.
The RSPB's Volunteer and Farmer Alliance project was launched in southern England in 1999 because of concerns over declines in the numbers of many farmland birds.
Since then more than 4,000 farms across the UK have been involved, and around 500 farms are visited every year.
With the launch in northern England, the scheme now covers the whole country.
Thanks to the enthusiasm of farmers who are already involved in the project, the RSPB has seen welcome recent increases in birds such as reed buntings, song thrushes and tree sparrows in some areas.
Sarah added: "This project provides valuable information and support for farmers who want to do more to help wildlife on their farms.
"The scheme combines the knowledge and enthusiasm of birdwatchers with the interest of farmers to learn more about the birds and other wildlife present on their land. Better still, it's a free service."
