Thank you John Packham for this panorama of the nature reserve in Autumn (click on the image to see an expanded version).
This is a photo from the top of the site back in June 1990. It's a little hard to discern what is going on given the quality of the photo but possibly not a lot of horticulture. Someone suggested it looks like Richmond Park with sheds. If you have any really old photos of the site we would love to see them.
