response to possum control

Rapid recovery of kohekohe (Dysoxylum spectabile) following possum control

We document the rapid recovery of kohekohe (Dysoxylum spectabile) canopy cover following the control of brushtail possums (Trichosurus vulpecula) in Motatau Forest, Northland, New Zealand. Possum trapcatch rates were reduced from 25.6 ± 14.9% (mean ± SE) in 1997 (prior to control) to 2.7 ± 3.1% in 1999, but were little changed in Okaroro, an uncontrolled area nearby. Mean canopy cover scores for kohekohe in Motatau increased from 16.1 ± 4.5 % in 1997 to 52.6 ± 5.2% in 1999, but increased far less at Okaroro, from 42.3 ± 6.3% to 48.0 ± 7.75%.
