There are a variety of approaches for such models, but a projection matrix with 3 or 4 stages (seeds; seedlings and/or saplings; reproductive adults) and corresponding transition probabilities (incorporating survival, growth, and reproduction), is a reasonable minimum for many situations, allowing estimates to be made of the finite rate of population increase (k) or population (or metapopulation) growth rate [r = ln(k)] (Caswell 2001).…”

A standardized set of metrics to assess and monitor tree invasions

Scientists, managers, and policy-makers need functional and effective metrics to improve our understanding and management of biological invasions. Such metrics would help to assess progress towards management goals, increase compatibility across administrative borders, and facilitate comparisons between invasions. Here we outline key characteristics of tree invasions (status, abundance, spatial extent, and impact), discuss how each of these characteristics changes with time, and examine potential metrics to describe and monitor them. We recommend quantifying tree invasions using six metrics: (a) current status in the region; (b) potential status; (c) the number of foci requiring management; (d) area of occupancy (AOO) (i.e. compressed canopy area or net infestation); (e) extent of occurrence (EOO)(i.e. range size or gross infestation); and (f) observa-tions of current and potential impact. We discuss how each metric can be parameterised (e.g. we include a practical method for classifying the current stage of invasion for trees following Blackburn's unified framework for biological invasions); their potential management value (e.g. EOO provides an indication of the area over which management is needed); and how they can be used in concert (e.g. combining AOO and EOO can provide insights into invasion dynamics; and we use potential status and threat together to develop a simple risk analysis tool). Based on these metrics, we propose a standardized template for reporting tree invasions that we hope will facilitate cross-species and inter-regional comparisons. While we feel this represents a valuable step towards standardized reporting, there is an urgent need to develop more consistent metrics for impact and threat, and for many specific purposes additional metrics are still needed (e.g. detectability is required to assess the feasibility of eradication).

“…Despite a number of empirical and theoretical studies (Lonsdale 1999, Zedler and Kercher 2004, Davis et al 2006, Meiners 2007, Sebert-Cuvillier et al 2007, there is still no general model about why or when settlement becomes invasion. Both the attributes that make a species an invader (Kolar and Lodge 2001) and the characteristics that predispose an ecosystem to invasion (Sebert-Cuvillier et al 2007) are still weakly understood.…”

“…The invasion of native species by exotic species has become one of the most serious threats to biodiversity and ecosystem functioning (Vitousek et al 1996, Lonsdale 1999, Williamson 1999, Sebert-Cuvillier et al 2007). Exotic species can ruin the ecological health and economic value of ecosystems (Williamson and Fitter 1996).…”

The invasion of native species by exotic species is one of the most serious threats to biodiversity and ecosystem functioning. Despite a number of empirical and theoretical studies, there is still no general model about why or when settlement becomes invasion. The purpose of this work is to test a model of Bayesian population dynamics relying on bestresponse strategies that could help in resource management and bioeconomic modeling. Given the exotic species survival probability, our static game unveils a breaking-level probability in mixed-strategies, where it is in the interest of exotic species to invade and in the interest of native species to resist. In dynamic setting, we introduce a stochastic version of the balance equation based on conditional probabilities. When the exotic species survival probability and the availability of resources in the ecosystem are respectively high and low, the dynamics shows that the convergence of subpopulations toward steady-states operates at a high pace.

1. Since their introduction to North America, zebra mussels (Dreissena polymorpha) and quagga mussels (Dreissena rostriformis bugensis) have rapidly colonized North American fresh waters. Strategies for limiting the economic and ecological impacts of zebra mussels exist, but there are few examples where once zebra mussels have invaded a natural body of water they have been removed or managed without the use of ecologically destructive methods. The first successful attempt to eradicate a colonizing population of zebra mussels using SCUBA is reported here. Studies were conducted in Lake George, NY.2. Since zebra mussel larvae had been detected prior to the discovery of adults in Lake George, a comprehensive management programme for zebra mussels was in place when mussels were found in 1999, at a single location in the southern part of the Lake (Lake George Village site). Efforts were quickly launched to remove as many mussels as possible by SCUBA with the intent of minimizing the risk of the population reproducing and establishing a permanent presence in the Lake.3. Population size at the discovery site was initially estimated at fewer than 30 000 animals. Between 1999 and 2007 more than 21 000 animals were removed from the site, over 90% of them shortly after the colony was discovered. Continued monitoring of the site for larvae, recruitment, and growth suggests that the animals have not successfully reproduced since the project began. Since detection at the Lake George Village site, six separate colonizing populations at other locations in the lake were found and similar removal efforts appear to be having comparable success.4. This study demonstrates that the combination of early detection, suboptimal habitat, proactive establishment of a rapid response and management plan, and cooperation of a comprehensive network of stakeholders can prevent a successful zebra mussel invasion.
