Is an expert report explicitly required for this? Here (NRW) it was enough to explain that there is nothing there, along with a current photo of the fallow area.
The lady from the authority called it an expert report, but the gentleman yesterday said it was "only" a written declaration.
The gentleman was also there yesterday, literally climbed into the cypresses, took photos, and observed with his binoculars.
He said he will now write a two-page statement; although there are nests inside, they are old and have been "uninhabited" for a while. Therefore, nothing stands in the way of clearing. But of course, we are still waiting for the official approval.
