The work will look at bringing back traditional techniques such as coppicing to coax rare birds and butterflies back to underused woods in Morecambe Bay.
Morecambe Bay is home to the UK's last main colony, while the pearl bordered fritillary must be conserved to stop them dying out, said the commission.
Christopher Marrs, environmental consultant at TEP, said: "Open glades and rides provide forage opportunities for woodland birds assisting in their survival."
The Warrington-based environmental specialist is examining whether woodland management techniques such as coppicing can be increased on the 55,000ha area.
"Traditional techniques such as coppicing, thinning and ride management have become unpopular in recent years. But they are the best way to create more open habitats, which in turn attract more species."
James Anderson-Bickley, a regional woodland officer for the commission, said: "We want to conserve the important wildlife and support the rural economy."
