Spatial Economic Analysis of Early Detection and Rapid Response Strategies for an Invasive Species

Available Online

Burnett, Kimberly

Kaiser, Brooks

Economic impacts from invasive species, conveyed as expected damages to assets from invasion and expected costs of successful prevention and/or removal, may vary significantly across spatially differentiated landscapes. We develop a spatial-dynamic model for optimal early detection and rapid-response (EDRR) policies, commonly exploited in the management of potential invaders around the world, and apply it to the case of the Brown treesnake in Oahu, Hawaii. EDRR consists of search activities beyond the ports of entry, where search (and potentially removal) efforts are targeted toward areas where credible evidence suggests the presence of an invader. EDRR costs are a spatially dependent variable related to the ease or difficulty of searching an area, while damages are assumed to be a population dependent variable. A myopic strategy in which search only occurs when and where current expected net returns are positive is attractive to managers, and, we find, significantly lowers present value losses (by $270m over 30 years). We find further that in the tradeoff between search costs and damages avoided, early and aggressive measures that search some high priority areas beyond points of entry even when current costs of search exceed current damages can save the island more ($295m over 30 years). Extensive or non-targeted search is not advised however.

Petition to list the Porbeagle Shark (Lamna nasus) under the U.S. Endangered Species Act

Biodiversity Conservation

WildEarth Guardians

The Porbeagle Shark (Lamna nasus) is a remarkable fast, large shark that has adapted to cold waters in the northern and southern hemisphere through heat exchangers that keep its body warmer than surrounding waters. Its extensive range includes the North Atlantic, South Atlantic, South Pacific, South Indian, and Antarctic Oceans. Like other sharks, it is part of an ancient lineage stretching back more than 200 million years. Its evolutionary fine-tuning hasnt protected it, however, from a literal feeding frenzy by humans on sharks.

National Spill Contingency Plan (Palau) Draft

Secretariat of the Pacific Regional Environment Programme (SPREP)

The Government of the Republic of Palau has developed this National Spill Contingency Plan (NATPLAN) as part of its commitment to protecting our valuable coastal and marine resources from an eminent or substantial threat to the marine environment or public. NATPLAN has been developed to reflect the essential steps necessary to initiate, conduct and terminate an emergency spill response on, or into the navigable waters of the Republic of Palau, on the adjoining shorelines, the waters of the contiguous zone or into waters of the exclusive economic zone.

Secretariat of the Pacific Regional Environment Programme (SPREP)

The Pacific Islands Roundtable for Nature Conservation (PIRT) is a coalition of nature conservation and development organizations, governments, inter-government, donor agencies and community groups created to increase effective conservation action in the Secretariat of the Pacific Islands Region. It was formed in 1997 at the request of Pacific Island countries and territories. The forum enables those organizations working on nature conservation in the Pacific to improve their collaboration and coordination towards effective conservation action. It is the key coordination mechanism for the implementation of the Action Strategy for Nature Conservation in the Pacific Island Region 2008-2012. These are the final outcomes statement of their 13th Meeting which was held in Samoa 5-9 July, 2010.

In many communities , they do not value the management and the management of resources and the marine environment . The use of non- modern - for fishing with mask , net so hurry microfilm that many fish have been greatly diminished and damaged areas of fish , shellfish and wildlife the sea . It has become the buried part of the sea for land - new ( field ) and the performance of the fishery suitable as dynamite , to honor Guinea , chemicals and fames / buffetings much impact on the marine environment these problem is drastically reduced fish and seafood as well as the effects of natural disasters such as waves that storms like Val ( 1990 ) , Valerie ( 1991) , Heather ( 2004) and the tidal wave / tsunami ( 2009 )

Marine environment monitoring programme for Fagaloa and Uafato bays, Samoa : final report

Available Online

Kinch, Jeff

Vieux, Caroline

The Asian Development Bank through its contractor, the Snowy Mountain Engineering.Corporation were tasked with exploring the potential of augmenting the capacity of the Afulilo Reservoir to power a third turbine at the Taelafaga Hydro-power Station. To assist in this augmentation assessment, SMEC arranged with the Secretariat of the Pacific Regional Environment Program to oversight a consortium of partners to conduct a 11 month monitoring program with the purpose of assessing the status of the marine environment, particularly the coral reefs, as well as water quality in the Fagaloa and Uafato Bays. The data from the 2009-1010 marine monitoring program implies that several sites in Fagaloa Bay are exhibiting signs of various impacts from various inputs into the marine environment, which are most notable at sites 1, 2, and 14. These sites are closest to the apex of Fagaloa Bay where the Taelefaga Creek discharges into. Impacts for these sites include low or no coral cover and recruitment, growth in algal cover, lower salinity levels, higher rates of sedimentation and turbidity, as well as high nutrient inputs. Fish biomass at site 14 was also the lowest (sites 1 and 2 were not surveyed due to poor visibility). Other specific results across all sites include a reduction in live coral cover, a general shift to more hardier coral species, and low fish bio-mass when compared with other sites in Samoa.
