Species Management

There is a lot of uncertainty about how we pick the best invasive species management strategies to improve the environment, local economy, and human well-being, as invasive species management involves complex and multidimensional challenges. Invasive species management on inhabited islands is especially challenging, often due to perceived socio-political risks and unexpected technical difficulties. Failing to incorporate local knowledge and local perspectives in the early stages of planning can compromise the ability of decision-makers to achieve long-lasting conservation outcomes. Hence, including local knowledge and accounting for subjective stakeholder perceptions is essential for invasive species management, yet this often remains unaddressed. To address this gap, we present an application of invasive species management based on structured decision-making, and the resource allocation tool INFFER, on Minjerribah-North Stradbroke Island (Australia). We assessed the cost-effectiveness of six management scenarios, co-developed with local land managers and community groups, aimed at preserving the environmental and cultural significance of the island by eradicating European red foxes and feral cats. We further conducted a survey eliciting local stakeholders’ perspectives regarding the significance of the Island, their perception of the benefits of the proposed management scenarios, funding requirements, technical feasibility of implementation, and socio-political risk. We found that the best decisions when the budget is low are less cost-effective than when the budget is high. The best strategy focusses on control of European red fox on Minjerribah. However, our results also highlight the need for more research on feral cat management. This work demonstrates how to use a structured decision support tool, like INFFER, to assess contesting management strategies, this is particularly important when stakeholders’ perceptions regarding management outcomes are heterogeneous and uncertain.

The Impact

Biological invasions are recognised as a potentially major threat to biodiversity and may have considerable economic and social effects. Public, including pupils, attitudes may have large implications for invasive species management in terms of prevention, early warning and eradication success, but significant is the relations between the lay public’s visions of nature, their knowledge about non-native species and their perceptions of invasive species management. The more direct experience people have with the impact of invasive species, the more likely they will be able to understand the potential benefits of management programmes. The aim of our work was to prepare educational materials about invasive organisms for elementary schools. Some of them were subsequently applied directly in practice as part of an excursion in a schoolyard in west Slovakia, where up to six species of invasive plants were identified in the close proximity to the school. Keywords: Biological invasions, prevention, education, excursion.

Extension Professionals

Best practice management (BPM) guides are a key component of invasive species extension in Australia, and are becoming a more important way of reaching land managers with comprehensive invasive species management strategies. However, little is known about the quantifiable benefits of these guides as a stand-alone extension approach, or in comparison with other approaches. We therefore reviewed the existing literature to determine when this form of extension was appropriate, what determines the success or failure of BPM guides in facilitating best practice invasive species management, how effective they had been in the Australian context, and what methods were available to evaluate BPM guide effectiveness. BPM guides are most appropriately used in support of other forms of extension and enforcement of invasive species regulations; as a cost-effective alternative to more labour-intensive extension techniques; or in bringing together disparate information in a single comprehensive source for land managers and extension practitioners. They appear to be most appropriately distributed at mid- and late-stages of the invasion curve. Limited quantitative evidence of the effectiveness of BPM guides for invasive species in Australia is available, although there is a consensus that these materials are popular among target audiences, despite a range of studies having shown face-to-face extension to be more effective. Unfortunately, many factors make successful evaluation of a BPM guide difficult, such that extension professionals are less likely to consider the possibility of evaluation. However, we argue that extension professionals need to consider evaluation of written BPM guides, where time and funding makes this possible. Ideally this will involve formative evaluation to improve the content and messages of the guide, as well as summative evaluation to determine its effectiveness among the target audience and for the target species. We also suggest a range of economic evaluation possibilities that warrant further exploration and trial.

National Seashore

Interpretation designed to increase public understanding and appreciation of environmental issues can provide support for management actions in protected areas, but the relative impact of different interpretive strategies on public awareness and attitudes has not been adequately explored. The purpose of this research was to compare the effects of two interpretive programs (a non-personal, visual-based flyer and an interpersonal, audio-based talk) relative to a control group on visitors’ knowledge of, attitudes toward, and support for invasive species management at Cumberland Island National Seashore, Georgia. In general, the interpretive talk appeared to be more effective than the flyer at increasing awareness and generating support for invasive species management. Although visitors exposed to each of the treatments displayed greater knowledge of invasive species, effects on attitudes and management preferences were minimal. Future research examining the effects of interpretive media on public awareness of and support for controversial management decisions could therefore explore mechanisms for maximizing the impact of interpretive programming on visitors’ attitudes and preferences.
