Dr Nial Moores, Nationwide Director, Birds Korea
Following sixteen months of conferences, analysis (on birds by means of the yr and on invertebrates in the summertime final yr), seed assortment and preparation, and at last with receipt of all the executive and authorized permissions, restoration work correct lastly began in late March 2026 at our venture website in Maekdo Ecopark within the Gangseo District of Busan Metropolis.
This venture, kindly supported by SER and Microsoft, and carried out below Birds Korea’s MOU with the Busan Nakdong River Initiatives Administration Workplace, goals to transform a rice-field right into a floodplain-type wetland with a self-sustaining native plant neighborhood that can be utilized by foraging Jap Taiga Bean Goose 큰부리큰기러기 and different floodplain wetland species.
The sector is one in every of three (or generally extra?) in Maekdo Eco-park that’s planted annually with rice, which is then harvested – with a purpose to present grain artificially as soon as every week to geese and swans by means of the winter. Administration due to this fact means the sphere is stored dry by means of the winter; adopted by flooding and deep-ploughing and planting in spring; earlier than being harvested as soon as extra within the autumn and left to dry out by means of the winter. Our analysis on invertebrates final summer season unsurprisingly instructed somewhat low variety…
Whereas synthetic feeding has been genuinely important through the previous decade for delaying a decline of Jap Taiga Bean Goose 큰부리큰기러기 inside Busan, this administration strategy is pricey, labour-intensive, and sadly additionally will increase the chance of publicity of geese to illness, resembling Poultry Flu / Extremely Pathogenic Avian Influenza. It additionally advantages few different floodplain species; and an extra concern is that synthetic feeding applications could be stopped instantly.
Habitat enhancement, creation and restoration, alternatively, will help to cut back administration prices over the longer-term; will help with water high quality; often helps to assist a a lot wider assemblage of species; and may on this case be utilized by Busan Metropolis to assist promote progress towards the Sustainable Improvement Objectives.
The principle idea of our restoration venture at Maekdo is easy. As soon as all permissions had lastly been obtained, below supervision of Land Aura, the sphere was re-profiled, with a gradual slope, at deepest accessing the water desk at -50cm, in order that the sphere can assist a various assemblage of native wetland vegetation.
Subsequent, below the supervision of Prof. Byun Chaeho and his crew, a spread of seeding and planting approaches will be used to populate the sphere, within the understanding that various plant communities are wanted to offer foraging alternatives for geese and to stop fast colonization by native reed (which might in any other case quickly develop into too dense to permit use of the sphere by geese). Work with volunteers to do that planting was to have been on April 4th and 10th; however as a result of heavy rain, will now be later this week, on April 10th and 11th. All 110 volunteer spots seem to have been stuffed already.
As soon as planted and seeded, we are going to then proceed to observe the positioning and adjoining habitats for 2 years; assess success or in any other case; and as wanted, conduct additional planting and seeding.
All through, one a part of Birds Korea’s position has been to make use of this restoration venture to assist promote the worldwide significance of floodplain wetlands within the decrease Nakdong River, particularly by elevating the native and nationwide profile of the Jap Taiga Bean Goose 큰부리큰기러기.
It’s because the Jap Taiga Bean Goose 큰부리큰기러기 is a floodplain wetland specialist, which has advanced structurally to forage on wetland vegetation, typically by digging out their roots from smooth muds. The species is a superb bio-indicator. Conservation of the habitat of this species will assist to make sure the conservation of a various assemblage of extra floodplain species, together with vegetation, bugs, amphibians, mammals and wetland birds.
The species can be discovered frequently in internationally vital concentrations in Busan and at all the better-known southeastern floodplain wetlands (together with Upo, Junam and Hwapocheon). That is regardless that the Jap Taiga Bean Goose 큰부리큰기러기 is prone to be globally uncommon and declining quickly. There are few good knowledge nationally on Jap Taiga Bean Goose 큰부리큰기러기, nevertheless. Because of the problem of identification, the nationwide winter census, carried out below the auspices of the Ministry of Atmosphere, doesn’t even attempt to separate Tundra Bean Goose Anser serrirostris 큰기러기 from Taiga Bean Goose 큰부리큰기러기: they’re as an alternative nonetheless lumped collectively as “Bean Goose” (as they’re nonetheless by Wetlands Worldwide 2026).
This, we hope, will change. The Tundra Bean 큰기러기 and Taiga Bean Goose 큰부리큰기러기 are acknowledged as separate species by worldwide checklists resembling Avilist, and since 2025, by the Korean Ornithological Society (Birds Korea acknowledged them as separate species greater than a decade in the past, based mostly on e.g., variations in habitat desire, dimension, calls, plumage particulars and a scarcity of overlap in breeding areas). And the “Korean Non-Breeding inhabitants” of Jap Taiga Bean Goose 큰부리큰기러기 is at present estimated at solely 7,700 people by Wetlands Worldwide (2026) of their portal developed for utility of Ramsar standards. Certainly, the whole inhabitants of middendorffii (subdivided into three biogeographic populations) is estimated to comprise below 50,000 people. This makes Jap Taiga Bean Goose 큰부리큰기러기 probably rarer than the globally Endangered Swan Goose Anser cygnoides – a species with a (well-deserved) excessive conservation profile!
As is well-known by the Ministry of Atmosphere and we hope by native decision-makers with accountability for the conservation of biodiversity, Ramsar Criterion 6 states that: “A wetland ought to be thought of internationally vital if it frequently helps 1% of the people in a biogeographic inhabitants of 1 species or subspecies of waterbird” (see: https://wpp.wetlands.org/knowledge/Threshold ). The 1% threshold of the Korean Non-Breeding biogeographic inhabitants of Jap Taiga Bean Goose 큰부리큰기러기 is about at solely 75 people. Due to this fact, any wetland within the ROK supporting 75 or extra Jap Taiga Bean Geese 큰부리큰기러기 in mid-winter is internationally vital as outlined by Ramsar standards – whether or not or not it’s a Ramsar website.
Primarily based on accessible proof, the overwhelming majority of the Korea Non-Breeding Inhabitants of the Jap Taiga Bean Goose 큰부리큰기러기 winter within the southeast of the nation; and internationally vital concentrations of a number of thousand Jap Taiga Bean Geese 큰부리큰기러기 are common each mid-winter at Upo, Junam Reservoirs, Hwapocheon and in Ecoparks in Busan – all floodplain wetlands alongside the decrease Nakdong River.
Whereas Upo is already a well-known Ramsar website, and a few protections are in place at different websites, way more must be executed. First, a community is required to conduct simultaneous counts and to fill in lots of the remaining info gaps on their distribution and ecology. Second, their habitat must be enhanced in some areas (e.g., by lowering disturbance) and restored in others – we hope, supported by knowledge and expertise developed by means of this restoration venture. And third, somewhat stronger authorized protections are required for all these wetlands that assist Jap Taiga Bean Geese 큰부리큰기러기 in internationally vital concentrations.
This is the reason we contemplate our venture at Maekdo to be in some ways only a single step on a for much longer journey….Even so, it’s nonetheless fairly pioneering within the home context,
First, whereas most restoration is carried out by corporations below contract to varied authorities our bodies, this venture is being undertaken as a genuinely various collaboration, with assist from the Society for Ecological Restoration and Microsoft, and the deep engagement of: native authorities our bodies (together with the Busan Nakdong River Initiatives Administration Workplace, and the Nakdong River Estuary Eco-centre, who’ve performed a significant position in successful permissions); an impartial NGO (Birds Korea, the venture lead), working with members of different NGOs and networks, such because the Ricefield-Wetland Community; personal corporations (Microsoft, the environmental planning firm Land Aura, and likewise the Korean Birder YouTube channel); and lead teachers / researchers, together with Affiliate Professor Byun Chaeho at Gyeongkuk Nationwide College and Professor Ho Choi, at Seowon College; Professor Amael Borzee (advising on amphibian conservation from abroad); and Dr Kim Su-Kyung, a co-founder of Birds Korea who has many years of expertise in rice-field biodiversity monitoring and restoration of Oriental Stork 황새 – a high-profile floodplain species.
Second, as a various collaboration, this venture deliberately features a substantial awareness-raising ingredient, and stays totally open to new accountable companions. On this means, a YouTube video is below preparation by Korea’s prime chicken videographer Kim Eojin and we held seminars on the Nakdong Estuary Eco-centre in July and September final yr, and a gathering on April 4th this yr (once more – many, many because of the Centre for his or her facilitation and participation). The April 4th assembly was organized to debate a doable simultaneous survey of the Jap Taiga Bean Goose 큰부리큰기러기 at key websites for the species subsequent winter. The response appeared optimistic…Thanks to all who gave time to attend, and on your many priceless contributions.
After all, there may be all the time a lot to do – nonetheless. If you happen to can, please do be part of us!
