>Subject: Black robin monitoring
>New Zealand's Department of Conservation is presently reviewing its
>commitment to close-order monitoring of the Chatham Island black robin
>(Petroica traversi). The review is prompted by the need to consider
>competing species management priorities, in the context of severe
>Black robins survive in two small populations on the island reserves of
>Mangere and Rangatira (South East) in the Chatham Islands group. The
>species now numbers in excess of 200 birds, each of them individually
>colour-marked and behaviourally conditioned for easy observation.
>Active management of the robins ceased in 1989, but because the species
>is so intensely inbred (all living robins are descended from one female
>-- the revered 'Old Blue'), its populations have been monitored very
>closely since that time.
>>From the point at which Don Merton intervened to rescue the species 22
>years ago, the genealogical record of the robins is almost entirely
>intact. Trends in abundance, fertility, distribution and behaviour have
>been recorded also.
>In these respects, the species offers a rare opportunity to observe the
>recovery of a geographically isolated forest-dwelling insectivorous
>species as it emerges from a very severe genetic bottle-neck.
>A substantial investment has been made to rescue the robins from
>extinction and to guard against decline. For this reason, the Department
>is anxious to ensure that it has considered all authoritative views on
>alternative monitoring regimes and the research potential of the robins
>before it abandons or reduces contact with the populations. It seeks
>comment on the wisdom of these two options.
>It should be noted that once monitoring is reduced from its current
>intensity, contact with entire populations will be lost rapidly, and
>recovered only with the greatest of expense and difficulty. The lapse in
>the genealogical record will never be remedied.
>A discussion document has been produced which traverses the history of
>the robin recovery programme, the quite significant threats confronting
>the species, and the implications of concluding or reducing the
>monitoring regime. This paper is obtainable from the address below, or
>electronically from <>.
>Comment is invited by the end of February 1998. Expressions of research
>interest are also welcome.
