How can I help stop the spread of aliens?

Control of non-native species should be undertaken only after consideration of the risks posed by the species in question and balancing these against the cost effectiveness of any proposed action. 

In the case of the North American bullfrog, the risks posed are judged to be high.  Immediate action should be taken to confirm the species identification and remove any such animals from the wild.  In the case of most other non-native amphibians and reptiles, the risks are not fully understood - but learning about where these animals occur will help with ongoing assessment.  So, in all cases, please report your alien sightings.

Help to identify alien amphibians and reptiles is available from this site.  Just use the menu to the left to select species.
