There are some indexes for coral reefs evaluation and for enviromental quality monitoring using seaweeds. Does anyone knows or have developed an index of health that could help for monitoring, mapping or comparing seagrass meadows?
Hi, Beatriz!
I think you could contact Dmitry Lajus he has some publications devote to your quastion

Hi Beatriz,
There is much evidence that The Great Barrier Reef in Australia is degrading because of coal mining and agriculture runoff that deposit sediments and nutrients that induce many seaweeds to grow over the corals and cause their decline.
I dont have specific references at hand however.
Best wishes

You should check out Seagrass Watch - a community-based monitoring protocol that can be used to compare across sites http://www.seagrasswatch.org/home.html
Through NDVI index, you can assess remotely (in space and time) the quality and extent of seagrass meadowes (see work in Mauritania, of the research team of the NIOZ in The Netherlands)
Hola,
Creo que el documento adjunto te puede ser útil. Eso espero.
This is a protocol (attached) about how to measure an indicator to describe the state of seagrass meadows in the Southwestern Caribbean.
We worked on the ecological studies of Halophila ovalis in the Godavari estuary, we observed that shallow waters, moderate water temperature ( 18--25C ) moderate salinty (15-25 ppt) conditions and rich organic matter responsible for the growth of the seagrass meadows.
Dear Beatriz,
My MSc thesis may contribute to your question (with a systematic literature review in the Reference Section), please do help yourself:
