Zero bycatch the vision: New Zealand has a new National Plan of Action -Seabirds

New Zealand adopted a new National Plan of Action - Seabirds in May this year following an extensive consultation process that received over 3700 submissions (click here).

The plan’s Executive Summary follows:

“New Zealand is a centre of seabird biodiversity: of an estimated 346 seabird species, there are approximately 145 species that use New Zealand waters, and 95 species that breed in New Zealand. Many of these species’ activities overlap with fishing, which can lead to the bycatch of seabirds. The National Plan of Action – Seabirds 2020 Reducing the incidental mortality of seabirds in fisheries (NPOA Seabirds 2020), outlines the New Zealand Government’s ongoing commitment to reducing bycatch of seabirds in our fisheries.

The NPOA Seabirds 2020, like its predecessors, stems from a recommendation made in the UN (United Nations) Food and Agriculture Organisation’s International plan of action for reducing incidental catch of seabirds in longline fisheries (IPOA-Seabirds) in 1999.

The NPOA Seabirds 2020 is New Zealand’s third iteration of a national plan of action. New Zealand has embarked on a programme of transformational change in our fisheries management to ensure that our fisheries are world-leading in their sustainability and environmental performance. At the end of this period, we expect to have significantly increased monitoring and more responsible, low-impact fishing practices.

In recognition of this path to change, this NPOA Seabirds 2020 focuses on education, partnering to find innovative solutions to bycatch mitigation, and ensuring that all fishers know how and are taking all practicable steps to avoiding seabird bycatch.

In five years, monitoring capabilities will have expanded and we will have better information on seabird populations and how to avoid captures. This will allow for more direct management, including consideration of mortality limits or approaches as appropriate. We also expect that we will have a better understanding of seabird populations and behaviours, which will help us to identify other ways that we can ensure the long-term viability of our seabird species.

This NPOA Seabirds 2020 establishes the framework that the Department of Conservation (DOC) and Fisheries New Zealand will use to work together on seabird initiatives.

The NPOA Seabirds 2020’s vision is New Zealanders work towards zero fishing-related seabird mortalities.

Guided by this vision, the NPOA Seabirds 2020 has four goals:

1. Avoiding bycatch — effective bycatch mitigation practices are implemented in New Zealand fisheries

2. Healthy seabird populations — direct effects of New Zealand fishing do not threaten seabird populations or their recovery

3. Research and information — information to effectively manage direct fisheries effects on seabirds is continuously improved

4. International engagement — New Zealand actively engages internationally to promote measures and practices that reduce impacts on New Zealand seabirds

Each goal has objectives to be achieved within the next five years. We will report on our progress towards these objectives in a Seabird Annual Report, and will use the information it contains to set the following year’s priorities in a Seabird Implementation Plan. After five years, we will review the achievements and challenges of the NPOA Seabirds 2020.

The Seabird Advisory Group (comprising representatives from government agencies, key stakeholder groups and tangata whenua) will meet periodically to monitor and help implement the NPOA Seabirds 2020, and to consider new or arising matters related to the impacts on seabirds from fisheries.”

Kalinka Rexer-Huber (Parker Conservation, Dunedin, New Zealand) and colleagues have reported to the Conservation Service Programme of New Zealand’s Department of Conservation on research conducted on the Gibson’s subspecies of the Antipodean Albatross Diomedea antipodensis gibsoni and on White-capped Albatross Thalassarche steadi on the sub-Antarctic Auckland Islands.

The report’s summary follows:

“This report details the mark-recapture methods and findings for Gibson’s albatross and white-capped albatross at the Auckland Islands. We present data on the size of the Gibson’s albatross nesting population on Adams Island in 2020 and update estimates of survival, productivity, recruitment and foraging range to help identify causes of current population size and trends. For white-capped albatrosses we focus on estimating adult survival and document tracking methods and device recoveries.

Gibson’s albatross. Nesting success was 56%. The survival rate of adult females and males is once again similar, having recuperated from the dramatically low female survival recorded 2006–08. However, at 90% the survival rate for both sexes remains 6% lower than before the population crash in 2005, and is probably incompatible with population recovery given ongoing limited chick production. The total estimated number of breeding pairs of Gibson’s wandering albatrosses showed slow improvement 2008–13, but these gains appear to have stalled. In 2019–20 the island-wide breeding population (3,861 pairs) was the lowest recorded since the years following the crash (2008–10). In the study area 96 albatross pairs bred in 2019–20. This is the first time nest numbers there have fallen below 100 since the crash 2006–08. There were only seventeen new recruits into the study colony (new breeding birds banded). Breeding and non-breeding/failed females have different survival rates. Satellite tracking in 2019 showed breeding birds foraging largely in the Tasman Sea, while those that had failed moved further west into the Great Australian Bight. Together, survival, breeding numbers and recruitment show the slow Gibson’s albatross population recovery recorded over the decade 2007–16 has stalled.

White-capped albatross. Banded white-capped albatrosses were resighted at a rate of 0.26 in the study colony of 679 banded birds. Four GLS tracking devices were retrieved, and one further bird which had lost its GLS (or had it removed) was resighted. Adult survival is estimated as 90% (95% CI 86–93), taking into account different detection rates of nesting birds and those not on nest during colony visits.”

Most comments received by ACAP suggest that this year’s inaugural World Albatross Day went off well, with the conservation crisis facing albatrosses being brought to the attention of new audiences around the world.  With 19 June now long past it is perhaps surprising there is still a need to thank some of the supporters of ‘WAD2020’: we can blame COVID-19 pandemic for that!  ACAP’s Information Officer has been largely self-isolating in his Cape Town home during 2021, but with South Africa easing restrictions by moving to Level One last month he has been able cautiously to get out to thank colleagues for their WAD2020 contributions – at a social distance in the open air of course.

This week he met up with Michelle Risi, who had returned a few days previously from two years working for the Gough Island Restoration Programme (GIRP) on the island (click here) to offer his personal and ACAP’s thanks for her support of WAD2020 and to hand over some albatross posters and postcards.  Indeed, the original impetus for a World Albatross Day came from Michelle’s suggestion, and following her co-option to ACAP’s WAD Intersessional Group she persuaded her contacts to help by designing pro bono a WAD2020 logo by commercial artist Geoffry Tyler and a poster by award-winning illustrator Owen Davey.  Along with Melanie Wells from Australia, she led on setting up the popular World Albatross Day Great Albicake Bake Off – and baking a couple of cakes for the competition herself.  Michelle is an excellent photographer, and some of her best work has been made into WAD2020 posters as well inspiring artworks by the Artists & Biologists Unite for Nature (ABUN) group.

Michelle and husband Chris Jones hope to return to Gough next year to help with the GIRP mouse eradication exercise, called off this year as a consequence of the pandemic causing a disruption of international travel.

With grateful thanks to Ria Olivier of the Antarctic Legacy of South Africa project which sponsored the printing of WAD2020 posters and postcards as well as donating island books published by ALSA as competition prizes.

Tracking Flesh-footed Shearwaters in New Zealand

Patrick Crowe (Wildlife Management International, Blenheim, New Zealand) has reported to the Conservation Service Programme of New Zealand’s Department of Conservation on research conducted on two breeding populations of the globally Near Threatened Flesh-footed Shearwater Ardenna carnepeis

The report’s abstract follows:

“This report covers the findings from the second of three years’ flesh-footed shearwater (Puffinus carneipes) research under Conservation Services Programme project POP2018-04. Here we report on the ongoing population monitoring of flesh-footed shearwaters on Ohinau and Lady Alice Islands and the results of GPS tracking of breeding birds from both islands.

During the 2019/20 breeding seasons we monitored 274 and 288 study burrows on Ohinau and Lady Alice Islands respectively.  A total of 216 study burrows on Ohinau Island were breeding and we were able to identify 408 of the 432 (94%) partners occupying these study burrows.  On Lady Alice Island, 202 study burrows were breeding and 358 of 404 (89%) of partners occupying these study burrows were identified.  We were unable to determine breeding success for the 2019/20 season but the rate of failure during incubation in January was similar to the 2018/19 season.

Breeding flesh-footed shearwaters were tracked simultaneously on Ohinau and Lady Alice Islands during the incubation and chick-rearing stages. On Ohinau Island, GPS devices were deployed on 26 individuals during incubation and 27 individuals during chick-rearing and this yielded 21 tracks and 50 tracks respectively.  On Lady Alice Island, GPS devices were deployed on 29 individuals during incubation and 34 individuals during chick-rearing and this yielded 20 tracks and 55 tracks respectively.

The average length of incubation foraging trips was 11.8 days and 4665 km for Ohinau Island birds and 16.6 days and 4734 km for Lady Alice Island birds. Lady Alice birds undertook significantly longer trips in respect to duration.  The average length of foraging trips during chick-rearing was 3.1 days and 1205 km for Ohinau birds, and was 4.8 days and 1536 km for Lady Alice birds. There was considerable variation in all aspects of foraging trips during chick-rearing which is likely due to a dual-foraging strategy.

There was considerable overlap of foraging areas between Ohinau and Lady Alice birds indicating that birds from different populations mix at sea during the breeding season.  All birds from Ohinau Island foraged either down the East Coast of the North Island or out towards the Louisville Ridge. During incubation, nearly half of Lady Alice birds foraged in the same locations while the remaining birds foraged inshore off the West Coast of the North Island or offshore in the Tasman Sea. During chick-rearing, areas closer to each of the colonies had greater importance but birds still utilised some of the more distant foraging locations identified during incubation in order to maintain their own body weight and condition.”

The Flesh-footed Shearwater has been identified as a potential candidate for ACAP listing (click here).

R. Costa (Departamento de Biologia, Universidade de Aveiro, Portugal) and colleagues have published in the journal Marine Pollution Bulletin on entangled seabirds received by a rehabilitation centre in Portugal, including six out of 77 Critically Endangered Balearic Shearwaters Puffinus mauretanicus.

The paper’s abstract follows:

“Plastic pollution and the subsequent entanglement of marine animals is a global and increasing problem.  In this study we present an analysis of the seabirds recorded as entangled by a rehabilitation centre and an associated marine animal stranding network, along the central coast of Portugal, between 2008 and 2018.  Results show a high annual rate of entangled seabirds (average 6.9%) compared to other studies and fisheries related materials are a relevant cause of seabird entanglement (82%) compared to other debris.  When comparing age classes, juveniles were more vulnerable to entanglement than other age classes in the species studied.  Regarding the rehabilitation of entangled seabirds, the release rate was higher in non-fishing material entanglement cases.  In conclusion, this study highlights the impact of fisheries related material on marine fauna and the need for reinforcement of the existing legislation for protecting seabirds and the implementation of mitigation measures associated with fishing activities.”
