“…The possibility of eradicating introduced species is seductive, but scientists are often pessimistic (e.g., Dahlsten 1986;Whitten and Mahon 2005), especially for invertebrates, plants, and aquatic species in general. Part of the pessimism is due to a few highly visible, expensive, failed eradication campaigns with notable non-target damage, such as efforts to eradicate the red imported fire ant Solenopsis invicta Buren (Buhs 2004) and the gypsy moth Lymantria dispar L. (Spear 2005) in the United States.…”

Pessimism about the prospects of eradicating invasive species or managing them at acceptably low densities is fostered by publicity about failures, but it is often unwarranted. Many species, including insects, plants, and aquatic invaders of various taxa, have been eradicated, and a variety of management techniques have maintained others at low densities for long periods. Many of these projects entailed low-tech, scorched-earth approaches, often using mechanical, physical, or chemical means. Others required sophisticated scientific research. There are at best rough guidelines rather than general rules about what approach to undertake. It is therefore important in each case to consider the full range of possible methods for eradication or long-term control, including the possibility of marshalling a massive amount of physical labor.

“…For example, many invaders produce seed banks, including almost all of the world's worst weeds (Holm et al . 1977), and seed banks are one of the most important factors limiting efforts to biologically control exotic weeds (Holloway 1964;Dahlsten 1986). Crawley, Harvey & Purvis (1996) found that British aliens were more likely than natives to have long-term seed banks, although this may not apply equally to all groups (Hodkinson & Thompson 1997).…”

Summary1. It has previously been hypothesized that low rates of attack by natural enemies may contribute to the invasiveness of exotic plants. 2. We tested this hypothesis by investigating the influence of pathogens on survival during a critical life-history stage: the seed bank. We used fungicide treatments to estimate the impacts of soil fungi on buried seeds of a taxonomically broad suite of congeneric natives and exotics, in both upland and wetland meadows. 3. Seeds of both natives and exotics were recovered at lower rates in wetlands than in uplands. Fungicide addition reduced this difference by improving recovery in wetlands, indicating that the lower recovery was largely attributable to a higher level of fungal mortality. This suggests that fungal pathogens may contribute to the exclusion of upland species from wetlands. 4. The effects of fungicide on the recovery of buried seeds did not differ between natives and exotics. Seeds of exotics were recovered at a higher rate than seeds of natives in uplands, but this effect was not attributable to fungal pathogens. 5. Fungal seed pathogens may offer poor prospects for the management of most exotic species. The lack of consistent differences in the responses of natives vs. exotics to fungicide suggests few aliens owe their success to low seed pathogen loads, while impacts of seed-pathogenic biocontrol agents on non-target species would be frequent.

“…Dahlsten 1986), there have been many successful eradications (Simberloff 2002a) as well as some highly publicized failures, such as attempts in the USA to eliminate the red imported fire ant Solenopsis invicta (Buhs 2004) and the gypsy moth Lymantria dispar (Spear 2005). Although eradication has a bad name in some management circles (e.g.…”
