Trapdoor Tally

Tally focuses on trapdoor species with open burrows (no lid), that are more easily seen. A 20-minute area search method was used, with the observer walking slowly, looking at the ground, recording any burrows seen (usually within 2m of the observer).

A metric ruler is used to measure the diameter of a sub-sample of burrows. Objectives of the Trapdoor Tally • To establish a set of monitoring sites where trapdoor burrows are counted annually using a robust, repeatable method. • To capture data about Trapdoor Spiders, that can be used as a reference for population trends, future planning decisions and conservation projects. • To provide data on the distribution and abundance of Trapdoor Spiders in the Greater Perth Region. • To raise awareness in the community about Trapdoor Spiders, some of which are endangered. • To engage the community in citizen science to assist with Trapdoor Spider conservation.
