A message from Dr. David Duffy, Pacific Cooperative Studies Unit (PCSU), University of Hawaii (posted 05 November 2012):

Because of a lack of funds, HEAR (www.hear.org) may close as soon as December 15, although there may be enough funds to extend it until February 15. This will mean several things. The web site will be placed on a new server although it is not clear who will pay for the server or for transitioning the site. HEAR data will not be updated. The Pacific Ecosystems at Risk (PIER) (http://www.hear.org/pier/abtproj.htm) site will also become frozen, as will numerous books, reports and papers (http://www.hear.org/). As software evolves we will likely lose the ability to access the data. The various list servers will need new owners, otherwise moderated lists will cease to function altogether, while other lists will not be able to add or delete members. The photo collection (http://www.hear.org/starr/images/?o=plants) will remain accessible, but only through a third party site that will charge for access.

I should point out that we have already lost the original homes of both the Pacific Basin Information Node (PBIN) and Pacific Ecosystems at Risk (PIER) although they have found temporary refuges. Together with HEAR, they represent the corporate memory both here in Hawaii and across the Pacific of efforts to sustain our natural ecosystems and agriculture against problems caused by species alien to the islands. HEAR also serves as the glue that holds the community together, providing information and facilitating communication. I just hope hindsight is kind to this decision.

Snowflake coral (Carijoa riisei) is a soft (non-reef forming), branching coral that grows attached to hard surfaces, forming carpets. Cylindrical (2-4 mm) branches have multiple polyps, which each have eight white tentacles (frilly when extended). Colonies cannot grow in direct sunlight; it can be found in shaded areas such as under ledges, in crevices, harbors, and in deeper water.  Carijoa riisei is believed to have been introduced to Hawaii and spread around the islands by hull fouling. It was first discovered in Hawaii in Pearl Harbor in 1972.  Carijoa riisei is native to Caribbean.
