Conservation Management & Biosecurities

Conservation Management
State personnel and volunteers will measure progress and effectiveness of the eradication by quantifying the parameters described below.

Outcome: Expand the resilient native plant community that supports seabird nesting and reduces storm and climate change damage
Metric:  Increase in the availability of quality habitat for ground and burrow-nesting seabirds
Specific Measure:  Percent cover of Verbesina, other non-native plants, and native plants in study plots sampled annually to coincide with growth period (see table 3).

Methods: To document changes in habitat quality, we created four vegetation plots (totaling 6.32 acres) within the region of open habitat most impacted by Verbesina (120 acres).  We quantify vegetation in each plot by measuring percent cover in randomly selected 2-meter quadrat sites that represent 5% of each plot (16-24 quadrats per plot).

Results: The eradication efforts and herbicide treatment schedule, developed over 5 years of experimentation on Kure, was effective at rapidly reducing the percent cover of invasive weeds and increasing native plant cover.

Best Management Practices (BMPs) to prevent the introduction of new threatening species to a fragile ecosystem, a set of protocols was created by PMNM to be utilized in order to sustain long-term field camp.

Attention to detail of prepping and vigilance throughout the process it the recipe for success.

Efforts to prevent the spread of invasive species to islands and sites that are currently free of them, and to reduce risks to the economy, environment, and human health through measures that involve prevention, surveillance, exclusion, incursion response, mitigation, adaptation, control and eradication

Biosecurity can be defined as efforts to prevent the spread of invasive species to islands and sites that are currently free of them, and to reduce risks to the economy, environment, and human health through measures that involve prevention, surveillance, exclusion, incursion, response, mitigation, adaptation, control and eradication”.

Box: Some key fundamental principles regarding biosecurity

– Prevention is better than cure: preventing colonization is more effective and cheaper than management measures after invasives have become established. Border control and strict abatement measures must be the first line of defense.

– Early detection & rapid reaction: eliminate invaders quickly. When preventive measures fail, locating the invaders before they have a chance to establish and spread is key to their successful eradication.

– A principle of precaution: In cases of uncertainty and insufficient scientific knowledge to accurately assess either the risk of a species becoming invasive or its present or future impact, one should assume that impacts will occur and action should be taken to prevent the species from spreading or becoming established.

The aim of this report is to provide basic biosecurity protocols for the transportation of vessels, people, and goods between atolls, with special reference to protected areas and islands of high biodiversity value. It also aims at identifying priority species already present and requiring a special attention as confirmed or potentially invasive species

Have in place as many lines of defense as practical

•Stop pests infesting gear destined for islands prior to departure:
•Practice good hygiene at source (e.g.home or supermarket)
•Implement effective quarantine practices – i.e., checking, secure packing & storage at the quarantine store.
•Check on the wharf or other points of departure before leaving – Stop pests reaching islands:
•Practice good hygiene on transport vessels and aircraft – Stop pests establishing themselves on islands:
•Check gear on arrival
•Conduct surveillance to detect pests and maintain detection systems
• Maintain contingency readiness and capability
