Management Action-Biosecurity

Invasive alien species are recognised as one of the leading threats to biodiversity and also impose enormous costs on agriculture, forestry, fisheries, and other human enterprises, as well as on human health. Rapidly accelerating human

Early Detection and Rapid Response (EDRR) systems are the first line of defence against invasive species once they have penetrated national or inter-island biosecurity systems. For these systems to be effective, a plan is required to coordinate the responsible agencies and ensure both the systems and equipment to address the detected species are in place prior to the response. Several countries have developed these plans recently, which are available on the Battler Resource Base. SPREP thanks James Stanford, who drafted the text for this guide.

As we experienced with the Taro Leaf Blight outbreak in the 1990s, the introduction of exotic pests or diseases into Samoa can have disasterous effects on our people and on our economy.

Invasive species pose one of the greatest ecological threats to America’s lands and waters. Their control can be complex and expensive and is often conducted in perpetuity; their harm can be irreversible. Early detection and rapid response (EDRR) actions can reduce the long-term costs and economic burden that invasive species have on communities.

Insects have presented human society with some of its greatest development challenges by spreading diseases, consuming crops and damaging infrastructure. Despite the massive human and financial toll of invasive insects, cost estimates of their impacts remain sporadic, spatially incomplete and of questionable quality. Here we compile a comprehensive database of economic costs of invasive insects. Taking all reported goods and service estimates, invasive insects cost a minimum of US$70.0 billion per year globally, while associated health costs exceed US$6.9 billion per year.

Pohnpei and their outer islands are very vulnerable to the introduction of Coconut Rhinoceros Beetle (CRB) because the CRB is present in Guam, Palau, Hawaii and South Pacific. Pohnpei is located near Guam, Palau and Hawaii and there is regular traffic by air and sea. For this reason it is very important that Pohnpei has a good Emergency Response Plan (ERP) in place not only for control/eradication but also for prevention and spread to other islands.

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.

Invasive species (non-native, harmful organisms) undermine human health and safety, food and water security, and economic development. Consequently, invasive species can have significant socio-economic impacts and warrant attention as a public policy priority. Trade and travel are the primary drivers of biological invasion both into and within the United States and prevention measures have been identified as the most cost-effective means of minimizing the introduction and thus impact of invasive species.
