“…Integrating management techniques may provide more effective control of an invasive weed than any technique in isolation (Paynter & Flanagan 2004;Henne et al 2005;Lym 2005) and may increase recovery of the native plant community, particularly if revegetation with natives is part of the management plan (Biggerstaff & Beck 2007). Cutting and Hough-Goldstein (2013) integrated weevil releases and plant competition in the form of a seed mix of native grasses and forbs to restore sites invaded by mile-a-minute weed.…”

Efforts to suppress an invasive weed are often undertaken with the goal of facilitating the recovery of a diverse native plant community. In some cases, however, reduction in the abundance of the target weed results in an increase in other exotic weeds. Mile‐a‐minute weed (Persicaria perfoliata (L.) H. Gross (Polygonaceae)) is an annual vine from Asia that has invaded the eastern United States, where it can form dense monocultures. The host‐specific Asian weevil Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae) was first released in the United States in 2004 as part of a classical biological control program. At three sites invaded by mile‐a‐minute weed, biological control was integrated with pre‐emergent herbicide use and two densities of native plantings. After 2 years, native plant cover differed significantly and was greater than 80% in the plots with plantings and pre‐emergent herbicide but less than 30% in the planting treatments without herbicide. Where mile‐a‐minute cover decreased at the two sites with the greatest pressure from exotic plants, plots were dominated by another exotic weed, Microstegium vimineum (Trin.) A. Camus, Japanese stiltgrass. The combination of biocontrol, pre‐emergent herbicide, and revegetation with native plants suppressed mile‐a‐minute weed, prevented invasion by Japanese stiltgrass, and increased the abundance of native plants. The selection of the management strategies used to control mile‐a‐minute weed determined the extent of recovery of the native plant community.

Aim This study aimed to document precisely the patterns of DNA ploidy variation in the native and secondary ranges of Lythrum salicaria distribution. The hypothesis that species invasiveness had been induced by a switch in ploidy level was addressed. Location Europe, Middle East, North America. Methods DNA ploidy levels of 1884 progenies of 578+ plants collected at 124 localities were determined by DAPI flow cytometry. Results Large cytotype variation (2x, 3x, 4x and 6x) was found across the native area of distribution (64 populations covering 12 European and two Middle Eastern countries). DNA hexaploids were detected for the first time, and rare DNA triploids were reliably confirmed. DNA tetraploids largely prevailed across the native range studied, while DNA diploids and DNA hexaploids were recorded only in Israel and Turkey, respectively. DNA triploid progenies occurred in one population from Hungary (together with DNA tetraploids). Sympatric growth of DNA tetraploids and DNA hexaploids was repeatedly encountered in Turkey. In contrast, cytotype uniformity was a typical feature of the invasive North American plants. Sixty populations, covering 13 states of the USA and provinces of Canada, were characterized by the presence of only DNA tetraploids. Main conclusions Several L. salicaria cytotypes (2x, 3x, 4x, 6x) occur in the native range of distribution, with much variation concentrated in the Middle Eastern countries, whereas only DNA tetraploids appeared to occur in North America. Our data show that the invasive spread of North American populations was not triggered by differences in ploidy level. Alternative explanations should be sought.

“…Purple loosestrife is estimated to occur in nine provinces in Canada (Blossey 2002). In Manitoba, purple loosestrife is estimated to cover 5,575 ha of habitat (Henne et al 2005;Lindgren, 2003). In the United States, Blossey et al (2001) indicate that purple loosestrife is found in the lower 48 states, except Florida.…”

We develop a monopolistic competition model of the horticultural industry and estimate the resulting profit function with U.S. and Canadian industry data. Combining the results with a hazard analysis of the characteristics of exotic plants introduced in North America, we explore optimal tax simulations for internalizing the risk and costs of a potential plant invasion. If the share of the exotic plant sales in final profits is large, then the resulting annual fee will be high, discouraging the expansion of the nursery industry. However, the annual revenues could fund efforts to mitigate the damages resulting from any accidental plant invasion.JEL classifications: D43, Q29
