Rewilding shapes the future of wetlands

The Global Rewilding Alliance connects partners around the world that are working within the same core themes to increase global impact through collaboration and shared strategies. Learn more about other important areas of focus for rewilding on the Working Groups page.

Our first working group focuses on wetlands, an important and highly threatened ecosystem that connects land, freshwater, and oceans. Wetlands are critical for life on earth, as they provide water and play a key role for the climate.

But despite their importance, wetlands are the most degraded ecosystem on the planet. Wild animals have been found to shape essential functions of inland and coastal wetlands, and yet the wild animals that inhabit them are the most decimated and threatened group of species globally. We must bring back the functionality of wetlands for the survival, wellbeing and prosperity of rural and urban communities around the world.

The future of wetlands will be shaped through rewilding efforts, in which intact food chains and the presence of wild animals in sufficient population numbers play a particularly critical role.

What are Wetlands?

The Ramsar Convention on Wetlands defines wetlands as “areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres”.

Five major wetland types are generally recognized:

  • Marine (coastal wetlands as coastal lagoons, rocky shores, coral reefs, and marine subtidal aquatic beds, which include kelp beds, sea-grass beds, tropical marine meadows);
  • Estuarine (including deltas, tidal marshes, and mangrove swamps);
  • Lacustrine (wetlands associated with lakes);
  • Riverine (wetlands along rivers and streams); and
  • Palustrine (meaning “marshy” – marshes, swamps and bogs)

The wetlands working group

18 Alliance Partners (and growing) have joined the Wetlands Working Group, including:

The Working Groups Process

STEP 1 Partners all around the world have been working on Wetland initiatives and studies individually. It’s time to bring them together.

STEP 2 The Global Rewilding Alliance brings together rewilding experts and practitioners to facilitate knowledge exchange & collaboration, and produce evidence, such as reports and research, to inform policy and practice.

STEP 3 The Global Rewilding Alliance and partners bring the evidence to governments, conventions, NGOs, etc. to shape policies that prioritise ecosystem functionality and wild animal recovery.

The Ramsar Convention on Wetlands

The Global Rewilding Alliance are helping share a rewilding-informed future for the Ramsar Convention on Wetlands and other global frameworks.

The Ramsar Convention on Wetlands is the intergovernmental treaty providing the framework for the conservation and wise use of wetlands and their resources. Rewilding is of high relevance for meeting the objectives of the Ramsar Convention on Wetlands. By adopting a rewilding perspective with ecosystem functionality and ecological character at the heart of its agenda, the Ramsar Convention on Wetlands could become a crucial pioneer in achieving a wilder, more resilient and stable future.

The Global Rewilding Alliance will be attending the 15th meeting of the Ramsar Conference of Parties (COP15) from 23rd to 31st July 2025 presenting the results of our wetlands working group. If you’d like to connect with our team on the ground at the conference please contact .

AFRICA REPORT

A special 154-page follow-up report to ‘Taking Animals into Account’, featuring the African continent and based on a literature review and a set of case studies.

By recognising the fundamental ecological role of wild animals – mammals, birds, fish, reptiles, amphibians, crabs, crayfish and other organisms, we will become better at managing and restoring the world’s inland and coastal wetlands. This will dramatically increase the ecosystem services of wetlands to the benefit of all people on Planet Earth.

Wetlands are critical for all life on earth

Rewilding wetlands and taking animals into account will boost the supporting services of wetlands such as:

1. Providing clean water
Wetlands are one of nature’s best water treatment systems. Wildlife act as ecosystem engineers – recycling nutrients, preventing harmful built-up by opening water channels, and boosting oxygen. They keep water flowing, clean and healthy.
2. Connecting wetlands to surrounding ecosystems
Wetlands are ecological hubs linking rivers, forests, grasslands, and coasts. Animals move nutrients, seeds, and energy across landscapes, strengthening biodiversity far beyond the wetland itself.
3. Increasing biodiversity
Through grazing, predation, seed dispersal, and habitat creation, animals shape dynamic, life-rich ecosystems. More wildlife creates more habitats and food webs. A positive cycle of life supporting life.
4. Supporting food & other products
Wetlands are among the most productive ecosystems on Earth. They support fisheries, agriculture, and livelihoods by providing fertile soils, freshwater, and natural resources essential to food security.
5. Buffering against droughts & floods
Wetlands act as natural sponges, storing water during floods and releasing it during droughts. Animal-created channels and depressions improve water retention, recharge aquifers, and strengthen resilience to extreme weather.
6. Cooling the regional climate & drawing down carbon
Healthy wetlands store vast amounts of carbon while regulating local temperatures. Wildlife enhance these climate benefits by maintaining wetland structure and function.
7. Offering recreational opportunities
Wetlands provide spaces for birdwatching, fishing, kayaking, hiking, and more. These experiences support mental and physical wellbeing while sustaining thriving nature-based economies, e.g. nearly $10 billion annually from birdwatching in the U.S.

Spread the word on social media

You could also help us spread the word about the importance of wetlands by downloading resources and social media captions and sharing them with your networks, including the resource Why Our World’s Wetlands Matter, and the Wild Animals Within Them.

Promoting a Rewilding Perspective at the Ramsar COP15 in Victoria Falls, Zimbabwe, 23-31 July

The Global Rewilding Alliance and IFAW have partnered on this 7-page analysis on how Parties to the Ramsar Convention could feed a rewilding perspective into the work and outcome of COP15 in Zimbabwe. Specific opportunities have been identified and the document gives the background and rationale for how to convene the rewilding perspective, especially linked to the role of wild animals.
