text: I did a detailed survey of the small area just NW of this note, bounded by East Camus Path, Pentland School Lane, and the gardens of Nos 5, 7 & 9.  The area is mixed woodland, mostly broad-leaf deciduous, but with some pine, holly and larch.  The main canopy is at 6-8m, and consists about 120 trees, of which 50 are north of the ditch.  There are about 8 trees with large crowns above the canopy, 10-15m high, in a line between the ditch and Pentland School lane (6 of which are mapped).  There is an understory of about 70 trees of 2-6m height, denser at the east and west ends.  The gound layer is nettles, brambles, ferns, moss, lichens and leaf mould, with some fallen trees.

  A quick look suggests that the area with the marker in, and the areas at the northeast edge of the park are similar. The area between the two paths in the northeast is of younger trees, and much lower density. The patch by Camus Ave is low density tall mature trees, of which over half are mapped.
  Cockmylane and white lady are much like the area I surveyed in detail.
