The lake is connected to Portsmouth Harbour
under the M275 motorway bridge, and to Langstone Harbour via Ports Creek,
around the top of Portsea Island. It has the same designations as Portsmouth
Harbour, i.e. Site of Special Scientific Interest, and Special Protection Area
for Birds. A cycle and pedestrian path, from Mountbatten Sports Centre up to
Hilsea roundabout, gives good views. The plant in the foreground on the left is Sea
Club-rush. The Jackstar sculpture (right) is intended to act as a roost for wading birds
at high tide. Little Egrets have become common in the harbours of recent times. One of their favourite spots is at the top of Tipner Lake, near to the Hilsea roundabout. You can almost predict where one will be standing!
Follow Tipner Lane all the way round, underneath the motorway, and you come
to a number of grasslands, hedges and embankments which are surprisingly varied
in structure and wildlife value. A survey of the whole area in 1991/2 gave a
total of about 130 plant species. Go right down to the shore and you can find
Duke of Argyll's tea-plant. Further inland there is a smattering of Bee
Orchids, such as the one shown here. South of Waterside Special School is Tipner Ranges, out-of-bounds to
casual visitors, but you can still hear the skylarks.
