English to French Science Biology (-tech,-chem,micro-) Marine biology

Line-intercept-transect or quadrat surveys (see English et al., 1997) of potential source areas for transplant material (which should be in a comparable environmental setting to the reef to be restored) ought to provide information on relative abundances of the main species and their densities.
These can be used to guide transplantation or at least provide long-term targets.
This emphasises the importance of restoration goals and defining a “reference ecosystem” state to which you are trying to restore a site. The difficulties of defining this state in the face of both global climate change and the widespread decline of coral reefs from anthropogenic impacts have been mentioned earlier. However, the perils of embarking on a restoration project without any goals and without any idea of the ///state you expect the restored reef to achieve,///seem far greater, with little likelihood of a successful outcome.

Reef restoration.
