[Coral-List] Recovering Acropora cervicornis populations

[Gwilym Rowlands]

Photos, site descriptions, maps, and the most recent assessments (?), of the
Acropora cervicornis patches to which Alina refers at Smith Bank (Roatan,
Honduras), are covered in the following publications:

-Rowlands GP, Purkis SJ, Riegl BM (2008) The 2005 Coral-bleaching Event
Roatan (Honduras): Use of Pseudoinvariant Features (PIFs) in Satellite
Assessments. Journal of Spatial Science 53:99–112.

Acropora cervicornis from satellite imagery using a textural operator.

There were several populations of healthy and really thick branches in
Curacao and Bonaire. Some of these were affected by a storm 
in 2008 I think which produced significant fragmentation and mortality. The
population in Caracas Bay, Curacao, was recovering 
well in the summer of 2009. Here in Puerto Rico there a small patches all
over the place. However, they are impacted by predation, 
algae overgrowth and the occasional white band outbreak.

Curious to know if anyone is aware of populations of  *Acropora cervicornis
*populations recovering naturally (i.e. without restoration help) on reefs
in the Caribbean in recent years.  AGGRA database is only current to 2004,
so if you know of a local population that is achieving decent cover of
staghorn coral since 2004, please let me know.

Thanks in advance,
Brittany
