Portsdown Hill is a ridge of chalk
that lies to the north of Portsmouth Harbour on the South Coast
of England. The north side of the hill is farmland, horse
paddocks and public open space, while the south side is a mix of
chalk grassland and scrub, much of it designated as a SSSI (Site
of Special Scientific Interest).
This website describes the open spaces managed by the staff and volunteers of the Portsdown Hill Countryside Service.
Besides the SSSI, there are other areas on nature conservation interest on the hill, including SINCs (Sites of Interest for Nature Conservation). A variety of landowners and agencies own and manage the rest of the hill including the MoD, local authorities and utility companies. Within these ownerships, fragments of the once widespread chalk downland habitat remain.

New permissive path
Volunteers have completed a footpath from Mill Lane to Pigeon House Lane, following the line of an old hedgerow between fields. The path needs to be well-used to keep it obvious, so please get out there and give it a try. It is hoped to create another path which connects with it, running from Pigeon House Lane up to the roundabout.
Insect survey results
With financial support partly from the Friends, Bryan Pinchen has again been surveying for insects. Amongst the Ivy Bees he has found the Nationally Scarce Conopid fly Leopoldius signatus, a late summer species typically found at Ivy. The bumblebee Bombus humilis has again been found, this is much rarer than the similar-looking Common Carder bumblebee, Bombus pascuorum. Both reports can be downloaded from the Wildlife page.
A Quick Guide to Berries
Here are pictures of all the berries you are likely to see on the hill.
Map showing compartments
There is now a map showing grazing compartments. Various other features will be added. See the SSSI part on the Places page.
There is a worrying amount of Cotoneaster, of various species, on the south side of the hill. It is not native to chalk downland but is capable of spreading easily by seed. Volunteers are engaged in controlling it either by digging it up or by cutting it down to ground level, hopefully without knocking too many berries off.
The Wildlife and Management pages make use of a lot of
material which was created by a regular volunteer, Hilma Miles.
She took hundreds, possibly thousands of photographs, and was
keen to help with the various daily tasks such as moving cattle
and scrub clearing. She died in her sleep while on holiday
trekking in the Himalayan foothills of Bhutan.
An obituary was published in the Southampton Daily Echo on 6th December 2008.
