Skylark Threat?

Hi, I live next to a small airfield that has recently been decommissioned. The owners are planning to return it to farmland. The problem is that there are quite a large amount of Skylarks that nest there. I'm so worried about them. The sound in summer is beautiful and I'm dreading the thought that they will lose their nesting site. Is there anything that can be done? I know nothing about Skylarks really - will they move on or will it be curtains for this group?
