The Southern African Plant Invaders Atlas (SAPIA)
The Southern African Plant Invaders Atlas (SAPIA) is a mapping project, launched in 1994, to collate information on the distribution, abundance and habitat type of invasive alien plants in Southern Africa. The SAPIA database is a computerized catalogue of some 40 000 locality records of more than 400 naturalized alien plants. The database incorporates records gathered by about 180 participants between 1994 and 1998 and from roadside surveys conducted by Lelsey Henderson between 1979 and 1993. A trimestrial newsletter is produced and provides information on the distribution of some invasive alien plants, new emerging weeds, up-dates on legislation, biological control of invasive plants.
