“…The resulting incursion responses by the New Zealand government cost the taxpayer approximately NZ$10 million dollars to ensure that ants from these three nests were eradicated. The approximate averted economic impact has been estimated at NZ$665 million over a 23-year period [7]. The ants pictured here are attacking a mealworm (Tenebrio molitor).…”

Corruption, development and governance indicators predict invasive species risk from trade

Invasive species have an enormous global impact, with international trade being the leading pathway for their introduction. Current multinational trade deals under negotiation will dramatically change trading partnerships and pathways. These changes have considerable potential to influence biological invasions and global biodiversity. Using a database of 47 328 interceptions spanning 10 years, we demonstrate how development and governance socio-economic indicators of trading partners can predict exotic species interceptions. For import pathways associated with vegetable material, a significantly higher risk of exotic species interceptions was associated with countries that are poorly regulated, have more forest cover and have surprisingly low corruption. Corruption and indicators such as political stability or adherence to rule of law were important in vehicle or timber import pathways. These results will be of considerable value to policy makers, primarily by shifting quarantine procedures to focus on countries of high risk based on their socio-economic status. Further, using New Zealand as an example, we demonstrate how a ninefold reduction in incursions could be achieved if socio-economic indicators were used to select trade partners. International trade deals that ignore governance and development indicators may facilitate introductions and biodiversity loss. Development and governance within countries clearly have biodiversity implications beyond borders.

“…Unpaid action by citizens is typically essential for the control of the biodiversity (and economic) costs of weeds (Hawke 2009;Cattanach et al 2013;Goldson et al 2015;National Biosecurity Committee 2015). Even compliance with legal rules is to some degree a voluntary choice, given the limited capacity of public agencies to supervise and intervene on private lands.…”

Abstract. Australia has many environmental regulations intended to alter the behaviour of rural landholders. One key issue relates to managing invasive plants and animals, where effective action requires sustained (and largely voluntary) action and sustained investment. Eliciting high levels of compliance is a difficult problem, because different landholders have widely different attitudes and motivations. What works with one group of people may not work with another, and indeed may be counterproductive.This study demonstrates the use of contemporary psychological methods to identify groups of landholders who demonstrate different attitudes and behaviours in relation to weed control. It shows that identifiable segments do respond differently to different mixes of regulation, incentives and community action. It suggests that some commonly promoted interventions may actually be counterproductive in encouraging desirable action with some groups.The study shows that behavioural precision is important in creating effective compliance strategies in weeds management, and it demonstrates some of the methods that may be used to achieve that precision.

“…Most of the more difficult and remote terrain is managed aerially by broadcasting 1080 (sodium fluoroacetate) to control pests (Goldson et al 2015;Byrom et al 2016). In 2014, 1080 was applied to over 694,000 ha during a mast seeding year to protect native birds (Elliot and Kemp 2016), with 845,839 ha planned for an expected mast seeding event in 2017 (Department of Conservation, 2016b).…”

Unmanned Aerial Vehicles (UAVs) and remote image sensing cameras have considerable potential for use in pest control operations. UAVs equipped with remote sensing cameras could be flown over forests and remnant bush sites, particularly those not currently receiving any pest control, to record the unique spectral signature of the vegetation and to detect the presence of possums (Trichosurus vulpecula) and the damage they cause. UAVs could then be deployed to precisely distribute either toxins or kill traps to these identified locations. Predator-free 2050 is an ambitious policy announced by the New Zealand Government where several pests, including possums, are to be eradicated by the year 2050. In order to achieve this goal, pests must be identified, targeted and controlled, requiring creative and novel ideas. UAVs provide flexibility, can fly in remote and difficult terrain, and are considerably cheaper to purchase and operate than the planes and helicopters currently used in conventional aerial pest control operations. Current challenges associated with UAVs include payload capacity, battery limitations, weather, and flying restrictions. However, these issues are rapidly being resolved with sophisticated technological advances and improved regulations. A directed and targeted approach using UAVs is an additional and novel tool in the pest management toolbox that could significantly reduce pest control costs, cover inaccessible areas not receiving any pest management, and will help New Zealand advance towards its predator-free aspiration by 2050.
