From £36 per year, membership directly supports our vital conservation work. Hence, saltmarshes act as a valuable natural flood-defence, dissipating wave energy and reducing scour.

Coastal saltmarsh develops on the middle and upper tidal levels where fine sediments offer a substrate in a low energy stable environment conducive to the growth of salt tolerant flowering plants. It is therefore important to ensure unimpeded tidal patterns on sites and that creeks are not canalised or infilled. The remaining fauna of sea wormwood is equally precarious, as are other elements of high zone situations. © 2020 BBC.

Bees and other invertebrates need help to reverse the catastrophic declines in their numbers. Expanding them, or restoring sites once taken over by farms and industry, could increase the amount of carbon stored, the researchers said. Salt marshes around the UK provide £1bn worth of coastal flood defences, according to one government report.

The destruction of much of the natural habitat can be traced back to early salt-production activities.
