Both the entrance from Honor Oak Road and the Canonbie Road entrance have indeed been cleared. Must be in preparation for something!

Old details are at DC/98/043123/X | The residential development of 116 Canonbie Road SE23 3AG and the former Thames Water Reservoir site Honor Oak Road SE23 with vehicular and pedestrian access onto Canonbie Road. (Outline Application).

The site was deemed a Site of Importance for Nature Conservation, and both the London Ecology Unit (now merged into the Greater London Authority) and the London Wildlife Trust objected to any development. There were seven rare plant and two rare insect species found on the site, with one of the insect species listed in the ‘Red List’ as endangered.

Been ding dong and battles ever since, so who knows what is proposed this time, but the area has been left well alone for quite some time, so it may be of even greater importance to both wildlife and developer alike now!!
