1. Anglers are a recognized vector for invasive fauna, with both intentional and accidental introductions reported worldwide. 2. The purpose of this study 2. The purpose of this study was to investigate the Iberian freshwater angler’s habits and perceptions related to biological invasions, using an international and bilingual survey in Spain and Portugal. 3. The results showed that anglers from both countries cover great distances to fish, and that they commonly visit several places and fish during consecutive days, representing a major risk for invasions. Yet, anglers’ activity patterns throughout the year are not constant: the summer months involve more intense activity and, hence, entail higher risk. 4. In both countries, the preferred fish species were invasive, and their introductions were reported more often than native species, with motivations being country-dependent. 5. The use of live bait was not frequent, but sometimes invasive species were used and the release of unused bait in the water was reported very frequently. 6. Most anglers recognize that introductions have environmental impacts and that anglers have an active role in intentional introductions. However, only a minority is aware of the angler’s role in accidental transportation of invasive species. 7. These findings on anglers’ behaviour patterns and perceptions may be used to model invasion risks and also improve monitoring and awareness programmes led by government agencies.

In 1999, the pinewood nematode (PWN) , Bursaphelenchus xylophilus was found and identified for the first time in Portugal and in Europe. Following detection, Portuguese authorities initiated the implementation of eradication measures during 1999 and 2000, following an alert provided to European Community officials; as a result, the nematode was confirmed to be confined in the Setúbal region, near Lisbon. A task force from the follow-up group (GANP) created by the Secretary of State for the Rural Development established a national eradication programme (PROLUNP) to (1) Contain PWN within the initial geographic limits; (2) Implement eradication measures; and (3) Monitor PWN at a national level. Research is presently being conducted both at universities as well as research institutes, focusing on the characterization ofBursaphelenchus species associated with maritime pine, as well as on the insect vector, Monochamus galloprovincialis. Recent reports indicate that the nematode may be present in Siberia (Russia), which would present a threat to Eastern European forestry. Efforts are presently being developed by several European countries to establish a research consortium to detect and study the possible presence of PWN, for a new PRAs. A recent workshop held in Portugal, in 2001, has been an oportunity for sharing experiences and techniques on detection and control. There is clearly a greater awareness of this issue in Europe.
