WEED ECOLOGY
Plant species most affected by bitou bush
Following extensive surveys in both fore and hind
dune communities along the coast we have identified many species
which occur less frequently or in lower abundance in bitou-invaded
and in managed areas.
These species can be considered to
be ‘at risk’ and should be included in replanting
efforts and monitored carefully to ensure regeneration. We identify
those species which are significantly different from those which
show a similar trend and we distinguish effects of management
due to intensive work by volunteers from effects due to extensive
aerial spraying in fore dunes.
