Shropshire Fire and Rescue Service have been called out on seven occasions since the end of February to grass fires around the area of the underpass in Whitchurch Drive, Wellington.
All of the fires have been started deliberately and on occasions there have been multiple seats of fires.
Whilst fire crews are dealing with these fires they are unable to respond to more serious fires or accidents.
Shropshire Fire and Rescue Service are working with West Mercia Police to reduce the number of incidents. If anyone has any information they are asked to ring West Mercia Police on 101 or Crimestoppers on 0800 555 111.
