For these species there was at least an educated guess available as to the agent of decline. No scientiﬁc study had been conducted to ascertain this, but management can start and the populations be monitored to see if the action is beneﬁting the species. If population numbers remain the same or decrease, then it is likely that the agent being managed is not the cause of the decline. Management can then be modiﬁed to target a different area of concern. For example, with Mecodema costellum costellum found on Stephens Island, it was believed that the lack of fallen logs as refuge may be limiting the beetle’s ability to increase in numbers.
Lewisii could be used to design such a survey. This could include live pitfall trapping from early spring to mid-summer at a series of sites which are least 123 26 disturbed in the area, ideally coupled with night searches on mild, calm nights during spring. If this was repeated over 2–3 seasons without success, then there could be some degree of conﬁdence in concluding that the species is extinct. However, if one or more populations was discovered, then a recovery plan would be an important requirement for this species.
Due to this, the section covering species proﬁles and workplans was broken into four parts, grouping the taxa into areas based on the main type of work required. The parts were: A. B. C. Beetles with recovery plans: Taxa requiring active management. Sufﬁcient information was available on these beetles to believe they were declining and that there was some urgency to act. Most importantly there was conﬁdence that the threats that had been identiﬁed could be managed. Four taxa came under this part of the document.
