this is just the first paragraph
8. Take from the wild
General information:
• The Wildlife Management Regulation authorises the collection of a limited range of amphibians from the wild without a licence. This authority applies to unlicensed persons only and allows the person to take least concern amphibians from the persons’ own land and keep them on their own land.
• The collector needs to understand that captive maintenance of the specimen taken may require substantial effort as well as time and money. Conditions outlined in section 9 of this code, Repatriation of the progeny of wild caught amphibians, will apply to the release of captive specimens and the keeper must be familiar with these before taking any specimen from the wild.
• Collectors should only take sub-adult specimens. Importantly, collectors should avoid taking specimens of breeding age or gravid (pregnant) females from the wild, as they will contribute to the maintenance of the wild frog population.
