In densely populated European countries like the Netherlands, old landscape elements such as ancient woodlands and ancient hedges are today rare. Owing to the introduction of exotic species and indigenous trees and shrubs imported from other climate zones, recognition of truly wild, i.e. autochthonous, individuals and populations is now problematical, posing challenges for forest management agencies, particularly at Natura 2000 sites. The author has developed a method for recognising genetically pure wild woody species, based on characteristics of the plant itself and those of the growing site. With this method, explained here, around 70% of the Netherlands has been surveyed, along with much of Flanders and part of the lower Rhine region of Germany. The results are illustrated with reference to two Dutch ancient woodlands, where new insights were obtained in terms of native status of the woody species and the ‘authenticity’ of the tree and shrub layer.

Trees And Shrubs

A survey of exotic beetles that attack trees or shrubs in New Zealand found 51 species of mainly Australian (58) and European (25) origin In addition three biological control agents have been released against woody adventive plant pests The host range of most species is restricted to exotic crop and ornamental plants in New Zealand Nine polyphagous borers sometimes attack dead wood of indigenous species and at least one polyphagous root feeder may attack indigenous trees but the ecological impact of these species on indigenous forests appears negligible However some of the wood and bark borers as well as several defoliators are important pests of exotic crop and amenity plants Although this suggests that exotic phytophagous beetles pose a greater biosecurity threat to exotics than to indigenous species a greater surveillance effort in New Zealands indigenous forests appears necessary to detect potentially harmful invasions
