The name 'Black Forest' is reputed to have been given as a result of the dark-coloured tree bark and thick green foliage.
The area formerly extended from the eastern foothill suburbs of Burnside, Erindale, Beaumont, Glen Osmond, south-west through to Urrbrae, Malvern, Mitcham, Unley, Goodwood, Wayville, South Adelaide, Black Forest, Hyde Park, Clarence Park, Plympton, Edwardstown, St Marys and the River Sturt near Marion.
The Urban Forest Biodiversity Program reports that grazing, agriculture, horticulture, residential development and industry have progressively all but replaced the unique flora and fauna of the Adelaide Plains. Less than 2% of the original habitat is left intact and remaining native plants and animals are finding it increasingly difficult to survive.
Individual trees from the original Black Forest still exist within the City of Unley but only one remaining stand of grey-box woodland can be found - in Heywood Park at Northgate Street, Unley Park.
