Integrating island restoration and eradication programmes will help maximise conservation gains for procellariiform and other seabirds

Peter Kappes (Department of Fisheries and Wildlife, Oregon State University, Corvallis, USA) and Holly Jones argue in the journal Biodiversity and Conservation that removing alien mammals from seabird islands should be followed by active restoration programmes to encourage seabirds to recover or return.  This seems particularly apposite for procellariiform seabirds with their particular life-history traits.

The paper’s abstract follows:

“Colonial nesting seabirds frequently drive island ecosystem biodiversity by maintaining ecosystem functioning and community dynamics.  Invasive mammal introductions to most of the world’s islands have ravaged insular seabird populations and had associated devastating ecosystem-wide effects.  Eradication programs remove invasive mammals from islands, with the goal of conserving and restoring island species and systems.  However, most eradication programs rely almost exclusively on passive seabird recovery to achieve these goals.  Unfortunately, the life histories of most seabird species are not conducive to passive recovery within a contemporary timeframe.  Seabird restoration techniques can effectively overcome life history related issues and significantly reduce recovery times for insular seabird populations, thereby reducing associated ecosystem-wide recovery times.  By integrating seabird restoration and eradication programs, practitioners can maximize conservation gains, expand funding opportunities, and restore island ecosystems and the biodiversity they support.”

WWF launches its International Smart Gear Competition for 2014 to reduce bycatch in fisheries

WWF's International Smart Gear Competition, launched in 2004, brings together the fishing industry, research institutes, universities and government to inspire and reward practical, innovative fishing gear designs that reduce bycatch - the accidental catch and related deaths of sea turtles, birds, marine mammals, cetaceans and non-target fish species in fishing gear such as longlines and nets.

“Designed to inspire creative thinkers, Smart Gear is a call for innovative ideas that have practical applications for fishing “smarter”—for increasing selectivity for target fish species and reducing bycatch.  The competition invites submissions of practical, cost-effective solutions to reduce fisheries bycatch, and offers cash prizes totaling US$65,000.”

The individual prizes are a Grand Prize of $30 000, two runner-up prizes of $10 000, as well as $7500 as a Special Tuna Bycatch Reduction Prize that identifies a solution to reduce the amount of bycatch found in both purse seine and longline tuna fisheries in the waters of the Western and Central Pacific Fisheries Commission, and $7500 as a Special Marine Mammal Bycatch Reduction Prize.

Competition judges include Svein Løkkeborg, International Marine Research, Norway and Ed Melvin, Washington Sea Grant, USA; both of whom have been involved with research aimed at mitigating seabird mortality by fishing vessels.

The competition opened on the first of March with an entry deadline of 31 August.  Click here for the competition entry rules.  After the prizes are awarded, WWF will work with each of the winners to bring their ideas to life and see them implemented in fisheries around the World.

First record of a South Atlantic Wandering Albatross breeding in the southern Indian Ocean

A female Wandering Albatross Diomedea exulans carrying British Museum of Natural History band No. 4001481 has been reported by the Centre d'Etudes Biologiques de Chizé breeding on Île de la Possession, French Crozet Islands in the southern Indian Ocean during January 2014.

This bird was banded as a chick on 17 November 2005 in Wanderer Valley on Bird Island in the South Atlantic by the British Antarctic Survey (BAS).  It has not been recorded back on the island since it fledged.

According to BAS records this is the first time a Bird Island bird has been seen ashore in the Crozets.  However, a French Wanderer (BS6639) banded as a chick in the Crozets on 8 January 1976 was recorded on Bird Island four years later on 25 January 1980: at quite a young age for a Wanderer to return to land.

In contrast, within the southern Indian Ocean interchange of over 60 Wandering Albatrosses has occurred between Possession and South Africa’s Marion and Prince Edward Islands, 1068 km apart, including of at least 19 fledglings from one locality breeding at the other.

ACAP Breeding Site No. 64. Albatross Island, a monitoring site for Wandering Albatrosses and giant petrels in the South Atlantic

Albatross Island (c. 100 ha) lies in the Bay of Isles towards the northern end of South Georgia (Islas Georgias del Sur)* in the South Atlantic.

The island’s vegetation is made up primarily of Tussac Grass Parodiochloa flabellataUnlike nearby Prion Island, Albatross Island is not open to tourism.  Although listed as a Specially Protected Area (SPA) it has not been formally so designated.  A permit is required to make a landing and a Code of Conduct has to be followed.  Albatross Island has been closed to all but researchers since 2004 and permits are issued only "under exceptional circumstances".  Unlike the nearby main island of South Georgia (Islas Georgias del Sur)*, Albatross Island has remained rodent free.

Annual visits to monitor incubating Wandering Albatrosses Diomedea exulans and other seabirds commenced in 1999 (click here).  A total of 129 pairs of Wandering Albatrosses was recorded on Albatross Island in January 2010, a continuing decrease from 140 pairs in 2009 and 174 pairs in 1999.  However, in 2012 140 pairs were present (click here), with 135 occupied nests reported for 2011, 133 in 2013 and 144 in  January 2014, the highest since 2008 (151) (click here).

"The surveyors think the pattern of numbers of breeding birds on the two islands [Albatross and Prion] in recent years shows the population is stabilising (with fluctuations), and is no longer decreasing over the longer term. However, without a wider survey of the population on the neighbouring islands, there is a possibility that the increase on these two islands may be influenced by birds from other islands moving from depleted colonies to areas where there are more birds. It is likely this possibility will be further assessed next year as a wider survey is currently at an early stage of planning."

Four to nine pairs of Light-mantled Sooty Albatrosses Phoebetria fusca have been recorded on the island from 2008 to 2103.

Study colonies on Albatross Island in January 2010 supported 35 pairs of Southern Macronectes giganteus and 27 pairs of Northern M. halli Giant Petrels.  Equivalent figures for the 2012/2013 breeding season are 45 and 20.  Nest failure of giant petrels in 2010 is thought to have been due to heavy snowfalls earlier in the season with many recently abandoned nests seen in January 2010 (click here).  In the 1980s censuses on Albatross Island revealed 173 pairs of Southern and 89 pairs of Northern Giant Petrels.  Complete-island surveys in 1999 resulted in 216 pairs of Southerns and 89 pairs of Northerns, suggesting a level of stability.

In addition to the four ACAP-listed species above, the  White-chinned Petrel Procellaria aequinoctialis breeds on Albatross Island.  Monitoring of this burrow-nesting species is no longer carried out on the island due to concerns over habitat damage from trampling.  Antarctic Prions Pachyptila desolata, Blue Petrels Halobaena caerulea, Wilson’s Storm Petrels Oceanites oceanicus and Common Diving Petrels Pelecanoides urinatrix also breed in burrows on the island.
