PLOS 09/09/11 Economic Impacts of Non-Native Forest Insects in the Continental United States

Worldwide, forests and urban trees provide important ecosystem services as well as economic and social benefits, but are threatened by non-native insects. More than 450 non-native forest insects are established in the United States but estimates of broad-scale economic impacts associated with these species are largely unavailable. We developed a novel modeling approach that maximizes the use of available data, accounts for multiple sources of uncertainty, and provides cost estimates for three major feeding guilds of non-native forest insects. For each guild, we calculated the economic damages for five cost categories and we estimated the probability of future introductions of damaging pests.

ACTU ENVIRONNEMENT 13/09/11 Ambroisie : la plante envahissante coûte cher

Entraînant asthme et réactions allergiques, l'herbacée pose un vrai problème de santé publique et fait l'objet d'une proposition de loi visant à coordonner un plan de lutte national. L'ambroisie à feuilles d'armoise (Ambrosia artemisiifolia) est aussi appelée Ambroisie élevée, Herbe à poux ou encore Petite herbe à poux. Derrière ces noms plus ou moins drôles se cache une herbacée annuelle originaire d'Amérique du nord. Envahissante, la plante introduite en Europe à la fin du XIXe siècle se répand de plus en plus vite sur le vieux continent, et notamment en France dans la vallée du Rhône et maintenant en Poitou-Charentes.

Problème, avec les changements climatiques, l'espèce, de la famille des Astéracées, produit plus de pollen, lequel est à l'origine d'allergies de plus en plus nombreuses. Une coordination tardive Les premières actions de lutte contre l'ambroisie datent d'il y a 10 ans. USDA - INVASIVESPECIES INFO - Plants - Economic impact.

SLATE 20/08/15 Les plantes exotiques envahissent le monde et font des ravages (qui coûtent des millions)

Les plantes envahisseuses sont là. Dans nos jardins, nos forêts, nos champs, de nombreuses plantes sont exotiques. Inoffensives dans leur région d'origine, elles font des ravages lorsqu'elles sont introduites par l'homme dans d'autres milieux, où elles perturbent l'écosystème végétal naturel.

En se basant sur une liste des espèces végétales exotiques naturalisées dans 481 territoires et 362 régions insulaires, une équipe internationale de scientifiques a évalué qu'il en existait 13.168 espèces, ce qui représente 3,9% de la flore vasculaire mondiale.
