Riparian water availability affects potential nitrogen pollution by Black wattle

The leaf nitrogen dynamics of invading Black wattle (Acacia mearnsii) under conditions of varying water availability in fynbos riparian zones have not yet been examined. C·I·B student Casparus Crous (South African Environmental Observation Network), C·I·B Core Member Karen Esler and colleagues had a closer look at the nitrogen dynamics across fynbos riparian zones in the south-western Cape.

Acacia seed banks can accumulate in the presence of biological control agents

A recent study by C.I.B PhD graduate Mathys Strydom (currently at the Academy of Environmental Leadership) found that annual seed input of invasive Australian Acacias is still high, despite the use of biological control agents.
