A recent paper published in the Journal of the Royal Society of WA, illustrates the recovery of a number of breeding seabird colonies on Rat Island since the eradication of black rats and cats. After being absent from the Island for approximately 60 years, seabird populations have seen dramatic increases with the re-establishment of breeding colonies in just 10 years.

“The seabird colonies began to re-establish within a decade of the eradication program and the number of species and breeding pairs on Rat Island increased dramatically in 2011 and 2012.”

However the establishment of these new colonies presents a number of management challenges on the Island where human development has changed in their absence. The Rat Island Management Plan has been developed to help address these issues.
