It's all class G airspace and hence available equally to all types of aircraft. No special measures as you call them are taken, but where the pilot wishes to use the service of ATC, an Air Traffic Service Outside Controlled Airspace (ATSOCA) may, workload permitting, be provided by either Farnborough or Odiham.
Gliders at Lasham plus (at present) the airliners coming and going for maintenance are not provided with an air traffic service but do have the service of an Air/Ground radio operator, whilst traffic at Blackbushe is provided with an air traffic service called Aerodrome Flight Information Service.
