Climate Change and Migratory Species: A Review of Impacts, Conservation Actions, Indicators and Ecosystem Services - the report is published at https://jncc.gov.uk/climate-migratory-species-report/
Dubai, 10 December 2023 – Climate change is already having catastrophic impacts on many migratory animals and their ability to provide vital ecosystem services to humanity according to a major new report of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), a UN biodiversity treaty.
Released today at the UN Climate Change Conference in Dubai (UNFCCC COP28), the report finds that the direct effects of climate change on many migratory species are already being seen, including poleward range shifts, changes in the timing of migration, and reduced breeding success and survival. Integral to the ecosystems they live in, migratory species support vital ecosystem services that both mitigate the impacts of climate change and increase the resilience to climatic hazards.
The study also emphasizes the urgent need to act now to help vulnerable migratory species adapt to a changing climate. Actions such as the establishment of comprehensive and well-connected networks of protected areas and other effective area-based conservation measures are crucial to support species movement in response to climate change, whilst direct human interventions, such as the translocation of vulnerable populations of species, will be needed in some cases.
Some of the key findings of the report include:
The study ‘Climate change and migratory species: a review of impacts, conservation actions, indicators and ecosystem services’ was commissioned by the Government of the United Kingdom of Great Britain and Northern Ireland through the Joint Nature Conservation Committee (JNCC) as a major contribution to the work of CMS on climate change, and prepared by the British Trust for Ornithology (BTO).
“Nature underpins the very fabric of our lives – the ecosystems, food and water security upon which we all depend, as well as the health of our economies. The challenges that these migratory species face as a result of climate change are a powerful demonstration of the need for coordinated global action to protect our environment, which is why the UK is taking a leading role in efforts to restore nature, halt biodiversity loss and achieve our stretching targets to protect 30% of land and sea by 2030.”

Secretary of State for Environment, Food and Rural Affairs of the United Kingdom of Great Britain and Northern Ireland

Biodiversity is declining globally at unprecedented rates, and climate change is one of the major drivers of this crisis. In 2021, the world’s leading biodiversity and climate scientists jointly sounded the alarm, stating that biodiversity loss and climate change mutually reinforce each other and neither will be successfully resolved unless both are tackled together. The Kunming-Montreal Global Biodiversity Framework adopted last year recognizes that nature-based solutions are essential in the fight against climate change in its Target 8. The conservation of migratory species and their habitats is an important part of the solution to both the biodiversity and the climate change crises.
“Migratory species are finely tuned to the rhythms of our planet. They depend on a delicate balance, journeying vast distances to reach habitats specifically suited for their survival and reproduction. However, climate change is severely disrupting these critical paths, altering ecosystems and affecting the availability of resources. This disruption serves as a crucial red flag, highlighting the broader implications of climate change not just for these species, but for the interconnected web of life on Earth. This report underscores the need for immediate and concerted global action to mitigate these impacts and protect the future of migratory species.”
Amy Fraenkel, Executive Secretary of CMS
Migratory species are important for ecosystem function and climate change mitigation, especially when they form a significant part of an ecosystem or aggregate in large numbers at particular times of the year. Many migratory species are related to the movement and dispersal of seeds and nutrients. Large migratory species can contribute to climate change mitigation through the decomposition of their faeces, which locks carbon into the soil or seabed, as well as through more complex processes, such as maintaining trophic webs that protect forest or seagrass beds important for carbon sequestration. Migratory species can also contribute towards climate change adaptation by enhancing ecosystem resilience; for example, seabird guano increases the nutrients available for coral reef growth, which in turn reduces coastal erosion.
The impacts of climate change on migratory species underscore the need for countries to cooperate on actions to ensure their conservation. CMS provides a vehicle for such cooperation, addressing migratory species across their range. By conserving migratory species and their habitat under CMS, countries can also achieve win-win solutions and directly contribute to the goals and targets of the Kunming-Montreal Global Biodiversity Framework and the Paris Agreement on climate change.
“This report sets out robust scientific evidence that climate change is already having a significant impact on many species around the world that are dependent on migration for their survival. The clock is ticking on the future for many iconic species. We owe it to them to raise global awareness that solutions are possible, and call on governments to use this report to take action, seeking out nature based solutions that will help migratory species and that can reduce the impacts of climate change.”
Professor Colin Galbraith, Former Chair of JNCC and CMS COP-Appointed Councillor for Climate Change
The launch of this major report comes in advance of the 14th meeting of the CMS Conference of the Parties, in Samarkand, Uzbekistan from 12 to 17 February 2024. This meeting will be one of the most significant global biodiversity gatherings since the adoption of the Kunming-Montreal Global Biodiversity Framework, and will address crucial conservation priorities, including priority actions to address climate change and its impacts on migratory species and their habitats.

About the Convention on Migratory Species (CMS)
An environmental treaty of the United Nations, the Convention on the Conservation of Migratory Species of Wild Animals (CMS) provides a global platform for the conservation and sustainable use of migratory animals and their habitats. This unique treaty brings governments and wildlife experts together to address the conservation needs of terrestrial, aquatic, and avian migratory species and their habitats around the world. Since the Convention's entry into force in 1979, its membership has grown steadily to include 132 Parties from Africa, Central and South America, Asia, Europe and Oceania.
About the JNCC
The Joint Nature Conservation Committee (JNCC) is the only statutory nature advisor to all four countries of the UK, providing robust scientific evidence and advice to help decision makers turn science into action for nature to guide the UK on a sustainable path. JNCC works across land, air and sea with partners throughout the UK, the UK Overseas Territories, the Crown Dependencies and around the world. For over 30 years JNCC’s trusted expertise, dedication and skills have underpinned nature conservation and recovery. To find out more about JNCC’s work visit jncc.gov.uk
BTO is the UK's leading bird research charity and works to secure the future for birds and nature. It uses its science, monitoring and data to inform good environmental decisions, inspiring others with the wonder of birds and empowering them to work with the organisation. A growing membership and up to 60,000 volunteer birdwatchers contribute to BTO's surveys, collecting information that underpins conservation action in the UK. BTO maintains a staff of 100 at its offices in Thetford, Stirling, Bangor (Wales) and Belfast (Northern Ireland), who analyse and publicise the results of surveys and projects. BTO's work is funded by BTO supporters, government, trusts, industry and conservation organisations. www.bto.org
