BLACK or WATER POPLAR
Populus nigra ssp. betulifolia
or Water Poplar is an uncommon tree in Britain, but there are plenty
in Hainault Forest thanks to planting by the London County Council in
1910 when the lake was created. They typically lean and have upward
pointing tips to the branches. Few female trees exist and there are
none in Hainault. They readily regenerate from a twig pushed into
moist earth. They can be seen by the lake outfall where a couple have
fallen in the past. On and alongside the mounds at the north end of
the lake are several more. A spiral gall on the leaf stalk can be seen
most years. In the plantation is a row of four or five Berlin poplars P.berolinensis which
have small diamond-shaped leaves on pendulous branches. They don't
appear to be doing well and may be dying back. A small Western balsam
poplar P. trichocarpa is found along the footpath on Dog Kennel Hill. It can be
recognised in the spring by the balsam scent when the buds open.
