The Ninth Meeting of ACAP’s Advisory Committee (AC9) will be held in La Serena, Chile over 9-13 May 2016.

Meeting documents and information papers for AC9 are now being posted to this website (click here).  These include the meeting agenda and a list of confirmed participants as well as financial and other reports from the ACAP Secretariat.

The meeting will be run by the Advisory Committee’s Acting Chair, Mark Tasker of the United Kingdom.  The Chair will be supported by the ACAP’s Secretariat consisting of Marco Favero, Executive Secretary, Wiesława Misiak, Science Officer and John Cooper, Information Officer, along with Juan Pablo Seco Pon and an interpretation team.

AC9 will be preceded by the Seventh Meeting of the Advisory Committee’s Seabird Bycatch Working Group from 2 to 4 May and the Third Meeting of the AC’s Population and Conservation Status Working Group on 5 and 6 May.

The European Commission has proposed that all relevant fishing vessels in the European Union implement measures to stop the accidental catching of seabirds in their fishing gear (click here)

The International Council for the Exploration of Sea (ICES) Working Group on Seabird Ecology (WGSE) has estimated that more than 200 000 seabirds die every year as a result of contact with the EU fishing fleet in EU and non-EU waters, including the ACAP-listed and Critically Endangered Balearic Shearwater Puffinus mauretanicus (click here).

The following text is taken from the proposed measures to reduce incidental catches of seabirds in the Mediterranean Sea, home of the Balearic Shearwater:

“Vessels fishing with longlines in the Mediterranean Sea shall use at least two of the following mitigation measures: bird scaring lines, weighted lines, setting the longline gear during the hours of darkness with the minimum of deck lighting necessary for safety” (see page 39).

In 2012, the European Commission published a Seabird Plan of Action in an effort to codify the actions needed from different national, regional and EU institutions to solve the issue of seabird bycatch across the EU. The new legislation now needs to be negotiated between the Council (i.e. Member States) and the European Parliament this year before it becomes enforceable law.

Rachel Buxton (Department of Fish, Wildlife and Conservation Biology, Colorado State University, Fort Collins, USA) and colleagues have published a review paper in the journal Biodiversity and Conservation on deciding whether active or passive management should follow alien eradications on seabird islands.

The paper’s abstract follows:

“Following the removal of an introduced species, island restoration can follow two general approaches: passive, where no further intervention occurs and the island is assumed to recover naturally, and; active, where recovery of key taxa (e.g. seabirds) is enhanced by manipulating movement and demography. Steps for deciding between these techniques are: (1) outlining an explicit restoration goal; (2) building a conceptual model of the system; (3) identifying the most effective management approach; and (4) implementing and monitoring outcomes.

After decades of island restoration initiatives, retrospective analysis of species' responses to active and passive management approaches is now feasible.

We summarize the advantages of incorporating these analyses of past restoration results as an initial step in the decision-making process.  We illustrate this process using lessons learned from the restoration of seabird-driven island ecosystems after introduced vertebrate eradication in New Zealand.  Throughout seven decades of successful vertebrate eradication projects, the goals of island restoration have shifted from passive to active enhancement of island communities, which are heavily dependent on burrow-nesting petrel population recovery.  Using a comparative analysis of petrel response to past predator eradications we built a conceptual model of petrel recovery dynamics and defined key site and species characteristics for use in a stepwise decision tree to select between active or passive seabird population management.

Active restoration techniques should be implemented when seabird populations are absent or declining; and on islands with no nearby source colony, small remnant colonies, highly altered habitat with shallow soil and slopes, and with competitive species pairs.  As we continue to restore complex island communities, decision-making tools using a logical, step-wise framework informed by previous restoration successes and failures can aid in increasing understanding of ecosystem response.

An Arctic or Northern Fulmar Fulmarus glacialis was photographed in New Zealand waters in the general vicinity of the Snares Islands on 9 February 2014 by fisheries observer Leon Berard (click here).

NOTE: file photo of an Arctic Fulmar, not of the New Zealand record

This exceptional record, likely to be the first ever for the Southern Hemisphere (there appear to be none for both Australian and southern African waters) has this month been accepted by the Birds New Zealand Records Appraisal Committee.

The bird was identified by differences in bill colouration from the more-expected Antarctic Fulmar F. glacialoides and that it was a dark-phase individual – not seen in the Antarctic species.  It has been suggested that the relatively small head and slim bill of the New Zealand bird indicates that it came from the North Pacific population rather than from the North Atlantic.
