Just as additional information to show how vulnerable such a population is and how fast the situation can change
here the data of observations from a subpopulation containing 3 connected sites

SW still has "perfect" habitat quality...just since this year wild boars destroyed a lot of the "weed layer"
beside that, I have no clue what happend here...
SE was perfect in 2006 and we tried hard to cut as much trees as possible but too many oaks...and we are not allowed to cut them
so there are still a few good spots left but the habitat as a whole is nearly dead
we just keep one last spot open now
SM never was good, it is just really small and even in summer just a few hours with sunshine...as you see looking at the numbers, it took 3 years until I realizd that they use this bad site...
oh and not a single animal from these subpopulation was ever found elsewhere later
oh and yes....the number of days per year at this subpopulation went down over the years ... but it would not have changed the final result even if I would have doubled the days...
