Where's warren?

on 10 Feb 2014 

Rabbit warren mapping has been the key activity at Bon Bon over the past couple of months and it was a task that’s probably a bit like trying to find Wally in the “Where’s Wally?” comics. Often they’re hidden in amongst Dead Finish (Acacia tetragonaphylla) and chenopod bushes; to find them requires plenty of patience and a sharp eye.

The mapping was completed by two local Indigenous mustering contractors from Kingoonya, Lenny Willis and his nephew Andy, who are both familiar with the local landscapes.  They rode motorbikes across 50 metre transects in the buckshot plains land system using GPS with data loggers to record the warrens.

This area represents 36,000 hectares (about 17% of Bon Bon) and between them, Lenny and Andy rode 5,000 kilometres to complete the task and recorded over 1,000 warrens.

This activity completes the second stage of the South Australian Native Vegetation Council funded project (with the first phase of the rabbit warren mapping completed in 2012). Precise information on the number and location of warrens in key areas of the property are now recorded and placed into detailed maps.  This will enable effective management of the rabbit population into the future (rabbits are the only feral herbivore on the Reserve and represent one of the biggest threats to the biodiversity).
