South African Plant Invaders Atlas phase 11 update
Lesley Henderson- ARC Plant Protection Research Institute
The SAPIA database and atlassing project catalogues localities, abundances and habitants of alien plant species growing outside of the cultivation.
SAPIA database and atlas project incorporates a roadside survey which was started by Lesley Henderson from 1979-1993. SAPIA phase 1 project started from 1994-1999 funded by Department of Environmental Affairs.
SAPIA phase 11 was launched in 2005 aims to continue Henderson roadside surveys and to encourage public participation. SAPIA phase 11 started on 2005-2010 funded by Department of Water and Affairs.
Particular emphasis is on emerging weeds and those proposed for legislation. SAPIA phase 11 will provide support for the South African National Biodiversity Institute (SANBI)’s Early Detection and Rapid Response of Emerging Invasive Alien Species project.
From 2012-2013 records were added to the SAPIA database with 1800 records from roadside surveys conducted by Lesley Henderson and 600 records from other SAPIA participants - 200 records from EDRR and 400 from other 17 contributors.
Eighteen species were added to the SAPIA database, of which 14 were new or emerging species. Emerging species recorded during the past year include common bee-bush (aloysia gratissima) onio weed (Asphodelus fistulosus), glory flower (Clerodendrum bungei), midnight lady (Harrisia pomanensis), Prickly Australian pest pear (Opuntia stricta var. dilleniir) and rabbit foot fern (Phlebodium aureum).
