Barely a week into 2010 and already the crazy crocodile stories are starting to appear. This one concerns the possible decline of freshwater crocodiles at the hands of expanding saltwater crocodile populations.
The story itself is clearly prompted by the release of the revised management plan which contains a graph showing the apparent decline in freshwater crocodiles detected during surveys of the Daly River.
I’m not sure that I’d be leaping to such conclusions based on the findings of one river system’s survey results just yet, especially considering the variability inherent in survey results. There’s no information in the report, for example, to assess the impact that changing the survey methodology in 1998 (the first year of the apparent decline) had on the results. It’s a good point to bear in mind when assessing croc survey data.
