Abstract Saltwater intrusion is the leading edge of sea-level rise, preceding tidal inundation, but leaving its salty signature far inland. With climate change, saltwater shifting landward into regions that previously have not experienced or adapted to salinity, novel transitions in biogeochemistry, ecology, and human land uses. We explore these changes their implications for adaptation coastal ecosystems. Biogeochemical changes, including increases ionic strength, sulfidation,...
This article examines the use of economic analysis to inform bioinvasion management, with particular focus on forest resources. Economics is key for understanding invasion processes, impacts, and decision-making. Biological invasions are driven by affect activities at multiple scales stages an invasion. Bioeconomic modeling seeks how resources can be optimally allocated across management activities—including prevention, surveillance programs early detection controlling populations spread—to...
Abstract Cost‐effective surveillance strategies are needed for efficient responses to biological invasions and must account the trade‐offs between effort management costs. Less may allow greater population growth spread prior detection, thereby increasing costs of damages control. In addition, usually applied in environments under continual invasion pressure where number, size location established populations unknown detection. We develop a novel modeling framework that accounts these...
Abstract As a bioinvasion spreads across landscape from its point of introduction, damages rise roughly with the square distance original invasion. It is thus generally beneficial, at scale, to apply eradication or containment controls early if not immediately upon discovery. However, an individual property owner only has incentives consider costs and benefits control on his/her own rather than potential landscape‐scale damages. Bioinvasions will therefore be under‐controlled in independent...
Explicit articulation of values and objectives is critical
Wood borers and bark beetles are among the most serious forest pests worldwide. Many such species have become successful invaders, often causing substantial, costly damages to forests. Here we design evaluate cost-efficiency of a trap-based surveillance program for early detection wood at risk establishing in New Zealand. Although costly, could lead earlier newly established pests, thereby increasing likelihood eradication reducing control costs from future invasions. We develop mechanistic...
International trade is a key pathway for the global spread of nonnative species. Historical and emerging flows interact with ecological dynamics to shape species risk determine how that can be mitigated. This article discusses these underlying processes, trends, role past future economics research in understanding managing risks from trade. We identify four priorities research. These include expanding economic analysis consider interventions across biosecurity continuum more comprehensively,...
Abstract This paper proposes a surveillance model for plant pests that can optimally allocate resources among survey tools with varying properties. While some are highly specific the detection of single pest species, others more generalized. There is considerable variation in cost and sensitivity these tools, but there no guidelines or frameworks identifying which most cost‐effective when used programs target newly invaded populations. To address this gap, we applied our to design trapping...
Preventing the establishment of invading pest species can be beneficial with respect to averting future environmental and economic impacts also in preventing accumulation control costs. Allee effects play an important role dynamics newly established, low-density populations by driving small into self-extinction, making critical influencing outcomes eradication efforts. We consider interactions between management tactics presence determine cost-effective time-efficient combinations achieve...
Abstract Early detection of new invasive pest incursions enables faster management responses and more successful outcomes. Formal surveillance programs—such as agency‐led surveys—are thus key components domestic biosecurity programs for managing species. Independent sources detection, such members the public farm operators, also contribute to early efforts, but their roles are less understood. To assess relative contributions different sources, we compiled a novel dataset comprising reported...
Ecological systems often operate on time scales significantly longer or shorter than the typical of human decision making, which causes substantial difficulty for conservation and management in socioecological systems. For example, invasive species may move faster humans can diagnose problems initiate solutions, climate exhibit long-term inertia short-term fluctuations that obscure learning about efficacy efforts many ecological We adopted a management-decision framework distinguishes makers...
Federal, state, and local governments in the United States, along with land trusts other nonprofit organizations, have invested significant financial resources protection of natural lands coastal areas. As climate changes, protected could provide increased resilience to communities, yet change also poses a threat continued existence healthy functioning these ecosystems. The objectives this research are characterize distribution types eastern estimate their exposure sea level rise, evaluate...
