Wetlands

Earth’s most valuable ecosystem per acre - and among the fastest disappearing.

The picture

Marshes, swamps, bogs and mangroves store carbon, filter water, buffer floods, and shelter an astonishing share of wildlife. We have lost a third of the world’s wetlands since 1970, but restoration is one of the highest-return actions in conservation.

The science

Wetlands cover ~6% of land but support ~40% of all species. Peat wetlands alone store twice as much carbon as all the world’s forests combined.

Worth repeating at dinner

Wetlands are disappearing three times faster than forests.

Coastal mangroves can absorb wave energy and blunt the force of storm surges.

What they face

Draining & development

Wetlands are filled for farmland and building, releasing stored carbon.

Ramsar

Pollution

Fertilizer and plastic runoff choke the water and its life.

UNEP

What is already working

Restore & rewet

Re-flooding drained land quickly revives wetland life and carbon storage.

Rain gardens

Home rain gardens mimic wetlands, filtering runoff before it pollutes.

Reasons for hope

Rewetting works fast

Restored marshes attract birds and store carbon within a few years.

Mangrove revival

Community mangrove planting is protecting coastlines and nurseries for fish.

Small actions that reach them

Cut water use today
Freshwater habitats and their species are among the most threatened on Earth.
~5 min
Catch rainwater for wildlife
Clean water and healthy runoff support amphibians, birds and insects, and ease pressure on rivers.
~45 min
Refuse one single-use plastic
8M+ tonnes of plastic enter the ocean yearly, harming turtles, seabirds and whales.
