Hither Green Triangle
Hither Green Triangle is owned by Network rail and managed with the assistance of Lewisham Council and the Friends Group. It is an area of land enclosed when the railway lines here were constructed in the nineteenth century. The high embankments surrounding the triangle were created then. The land at the base of the embankments is at the original height of the surrounding landscape. A water feature variously described as small stream, ditch or drain cuts through the triangle and its embankments and a pond occurs east of the stream. It was recognised as a site of nature conservation importance in Lewisham in the eighties.
There is a small pond on site which was restored thanks to s106 money.
This area had, for many years, been used as a depository for rubbish from station and engine sheds until its nature conservation potential was recognised in 1991. It was formally declared a nature reserve by a partnership of British Rail (as was) and the Borough Council in 1993, and this status is reflected by an informative sign on platform 5. The vegetation now receives periodic management from the Council's Nature Conservation Section to maintain the mosaic of habitats.
Flora and fauna
The site has a rich wasteland flora.
There is a good range of trees and shrubs are present particularly various willows' pedunculate oak, sycamore, hawthorn, elder, blackthorne and cherry. Considerable areas are covered in rough false oat-grass dominated grassland and tall herbs such as horseradish. Michaelmas daisy, hemlock, goat’s-rue, bristly oxtongue, Canadian golden rod and common nettle. There is a small pond from which common newt, frog and toad have all been recorded. This is enclosed by a wetland plants including fool’s watercress, pendulous sedge, reed sweet-grass, and yellow iris. Great horsetail (Equisetum telmateia), which is scarce in London, also occurs here
The northern slope is largely grassland, with a colourful array of wild flowers including oxeye daisy, common knapweed, wild mignonette and bladder campion. This gives way on the bottom of the hollow to bramble scrub and tall herbs, providing nesting cover for whitethroats and, in some years, lesser whitethroats. Most of the southern edge, adjacent to platform 4 at Hither Green Station, is wooded. A small stream trickles from north to south across the east of the site.
The sidings are a good area for migrant birds, with wheatear, whinchat, cuckoo and garden warbler all seen regularly in spring and autumn.
There is no general access to the site but the Friends do hold the occasional work session. For more details please contact the Council's nature conservation officer.
