From the 1st to 4th of March 2022, the spring tides were the opportunity for 7 members of the LEBCO team to operate their first annual biodiversity fieldworks on the “ecoblocs” incorporated in the seawall enclosing the EMR (Marine renewable energy) polder as part of the project CoEcoDigue (Ecobloc colonisation of the seawall enclosing the new polder of Brest harbour).
During this fieldwork there were:
- 27 “ecoblocs” surveyed
- 81 temperatures probes read and re-initialised
- 81 photo-quadrats taken
- 58 2x2m quadrats surveyed
- 14 intertidal rock-pools surveyed
- 3 carwash tokens used
All these data will enable our team, in the coming months, to evaluate the added ecological value of incorporating this kind of “green engineering” structure in a classic seawall riprap.
