The Introduction of Cane Toads to Australia PowerPoint by Eric Jiang Ecology Project 2011 What are Cane Toads Introduction and Spread The Ecological Effects

WHAT ARE CANE TOADS?

Cane Toads Cane Toads were originally from South America. Adults average 10–15 cm (3.9–5.9 in) in length; the largest recorded specimen weighed 2.65 kilograms (5.8 lb) with a length of 38 cm (15 in) from snout to vent. On the next slide it will show you the locations of the Cane Toad.

Cane Toad Distribution: Purple: Origins, Red: Distributed/Introduced

INTRODUCTION AND SPREAD

Introduction to Australia Cane toads were introduced to Australia from Hawaii in June 1935 by the Bureau of Sugar Experiment Stations in an attempt to control the native cane beetle.

The Spread of the Cane Toad Cane Toads were firstly bred in captivity, then in August 1935, 102 cane toads were released into the areas of Cairns. They spread rapidly around Queensland, and by 1978 they reached the border of NSW and by 1984 reached the border of NT.

ECOLOGICAL EFFECTS

Bad Ecological Effects The long term effects of Cane Toads are difficult to determine. There has been a drop in numbers of the Northern Quoll, have been observed after toads have invaded an area. There are a number of reports of declines in Goanna and snake populations after the arrival of toads.

Good Ecological Effects Numerous native species have been reported as successfully preying on toads. Some birds, such as the Black Kite have found attacking the belly doesn't have a risk of getting poisoned. Some frogs are eating the tadpoles of the Cane Toad.
