HEAR CLOSING      HEAR CLOSING      HEAR CLOSING

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.

"[Oxalis corniculata] may represent a Polynesian introduction or an indigneous species, as it was collected by the first botanist to visit the Hawaiian Islands...in 1779.... Further support for pre-contact introduction is given by the discovery of seeds of this species in archaeological remains in the Mauna Kea adze quarry complex.... This site was abanconed prior to contact (1778)." (Wagner et al. 1999. Manual of flowering plants of Hawaii [rev. ed.]. p. 1002)  Oxalis corniculata is native to an unknown range ("Cosmopolitan species of unknown origin....").
