plantation forest

The Canterbury Plains in the eastern South Island is one of the most modified regions of New Zealand with less than 2% of indigenous vegetation cover remaining. The critically endangered ground beetle Holcaspis brevicula Butcher, a local endemic known only from a small area in that region, is thought to be threatened by the loss and fragmentation of the formerly widespread forest and shrubland habitat. Previously, only the two type specimens, both male, were known to science. From 2000–2005, we conducted a survey for H.

Damage by introduced brushtail possums (Trichosurus vulpecula) to Pinus radiata trees was assessed in 41 compartments of a commercial forestry plantation on the Coromandel Peninsula, New Zealand. All the trees assessed were less than 3 years old. Possum damage in the compartments was low (median prevalence 3.3%) but highly variable (range 0–30%). Eight of 37 measured habitat factors differed significantly (P < 0.05) between the sites with damaged and undamaged trees.
