Altitude 99 metres

UHI, local runway, distance minor, busy rural.
This site seems a classic for erratic ground cover due to human activity.
A site sanity check using Google Street view produce a bizarre moment. The site is visible across a field. The camera car went down the minor road which is access to parking beside the airfield and turned around at the end. Not a problem except… it was either parked there for a year or there are older images.
Blue is available Street view. Met station to the left end of lighter green strip. Watch the ground covering at all points in these images.
There we are, car is being turning around, met wind tower, and a field of low shrubs/trees.
Lets try and go forwards
Change of focal length, moved sideways a bit, a metal tower in full sun is just visible and corn stubble! This is the ground cover currently showing apart from that fragment.
Shrubs? Lets see. Large image follows, click.
Top left circa 1999, top right 2009, lower left later 2009, lower right detail of what old runways might host.
Some of the fields are cropped with shrubs, as it seems to field by the met station was at some point. Yellow is starting to bloom oilseed rape, cropped far more of recent, farming practices change.
