This article gives a detailed account of the 1989 grassroots campaign which preserved the scenic Coquille Point headland from commercial development and led to its acquisition by the U.S. Fish & Wildlife Service as part of its national wildlife refuge system. For source material, I have relied heavily on local newspaper and city hall archives, supplemented by interviews with some of the local people who participated in the controversy. The article preserves the events of 1989 as a record for future historians and/or environmental activists. (Document has 33 pages - from references issue date assumed to be 2008))

The four sea turtle species found in Malaysia are the leatherback, olive ridley, green and hawksbill. The threats to these species are acute. Populations of leatherback, olive ridley and hawksbill turtles are on the brink of collapse – threatening a biodiversity crisis in Malaysia and the region. This proceedings contains 8 technical papers presented at a workshop convened in Kijal, Terengganu to chart new directions in the conservation of Malaysia's critically endangered sea turtles and to reverse population decline. They represent a wide range of issues from aspects of biology to a review of 40 years of sea turtle conservation. A paper on the socioeconomic linkages and impacts of fisheries was also included as the workshop adopted a multidisciplinary approach to address the issues. Two case studies, including successful restoration examples from international experiences and restoration efforts in Sabah, pave the way for enhancing turtle conservation in the country.

Evaluation of the potential for remote sensing to detect a relationship between wave action factors and plant re-establishment after a habitat enhancement at Lake Kissimmee, Florida. Using Geographic Information Systems (GIS) and remote sensing, wave action factors were found to be inversely related to the probability of plant re-establishment. However, correlation of wave action factors with areal coverage of aquatic plants based on field measurements, were unable to detect a significant relationship. Other factors aside from wave action, including littoral slope and the presence of offshore vegetation, may have influenced plant re-establishment in these sites. Remote sensing techniques may be useful to detect large changes in plants communities, however small changes in plant coverages may not be detectable using this technique.
