Weta
motels
Using hollowed-out
untreated pine or manuka blocks called 'weta motels' it is possible
to simulate the cavities found in mature trees that are used by
weta and other creepy crawlies. It will take many years for the
newly-planted trees to become old enough to develop these cavities,
so by using the weta motels we are accelerating the successional
process. Cave or tree weta colonise the motels as well as other
groups such as endemic spiders, leaf-vein slugs and pseudoscorpions,
some of which breed in the refuges. Entrance holes of weta motels
are small enough to keep predatory mice out.
Simulated habitat refuges
Lizard
Lodges
Placing two or
three sections of corrugated roofing material called Onduline (www.onduline.co.nz),
separated by 1cm dowel provides lizards, such as skink and gecko,
a safe and warm environment and protection from potential predators
such as rodents, hedgehogs, cats and mustelids.
Wooden
discs
Discs of untreated
pine, macrocarpa or other woods, 40-60 cm in diameter and 10-20
cm thick, can be used to simulate the fallen logs found in mature
native forests. The discs are dried and placed on bare soil.
These discs harbour
native invertebrates such as predatory spiders and ground beetles,
as well as snails, slugs, earthworms, flatworms, harvestmen, slaters
and even skinks (a type of lizard). Populations of these animals
can be monitored by carefully lifting the discs and counting the
individuals.
