Managed retreat and saltmarsh development
Between 2000 and 2006, Pisces Conservation monitored the development of a saltmarsh community following deliberate breaching of sea defences on the River Axe in north Somerset. As part of the managed retreat, the area was to be monitored for both physical and biological change over this period. Pisces were studying the development of the invertebrate community as grazing land reverted to a classic saltmarsh.

As part of the managed retreat, the area was to be monitored for both physical and biological change over this period. Pisces were studying the development of the invertebrate community as grazing land reverted to a classic saltmarsh.
Following initial investigations, bi-annual surveys were directed towards the spider, carabid beetle, amphipod and heteroptera or true bug components of the fauna. Overnight pitfall trapping was carried out to determine the community structure of these groups.
Pisces staff have many years' experience in invertebrate sampling methods and statistical analysis, and are able to draw on consultants with specialised knowledge of individual groups.
