Kelp forests are the rainforests of the sea — extraordinary productive ecosystems supporting diverse animal communities. Their recovery around British coasts offers major welfare benefits for marine life.
Kelp forest welfare significance mirrors that of other complex marine habitats — the animals dependent on kelp structure for food, shelter, and reproduction experience welfare harms when habitat degrades. Fish displaced from kelp forests by trawling face food stress and predation exposure. Seals that hunt in kelp lose foraging efficiency. The recovery of kelp following bottom trawling restrictions is one of the most encouraging examples of rapid marine ecosystem restoration available — demonstrating that welfare and conservation improvements can be achieved on human timescales with appropriate management changes.
