FR Effective conservation of the oceans relies largely on long-term monitoring of key species and habitats over wide geographical areas. This is notoriously difficult due to the high cost of such programs. As a consequence, we find ourselves with data ‘cold-spots’, areas for which we have little or no information. Citizen science, aka the involvement of volunteers or non-specialised people in science, is an increasingly popular way of conducting monitoring of species and ecosystems over a large...
The cynipid Dryocosmus kuriphilus is the most impactful invasive pest of Castanea sativa copse woods and orchards currently reported from many European countries. A low impact solution for the containment of this pest could be the use of resistant trees. We examined the resistance of the red salernitan ecotype (RSE) of C. sativa to D. kuriphilus and carried out a morphological characterization of this ecotype’s plants and fruits. From November 2015 to May 2017 we observed and recorded the percentage...
This paper describes a program of policy management and research from 2006 through 2015. It focuses on regulator efforts to understand and address challenges presented by dispersal of forest diseases and invasive pests in firewood by the camping public. Five surveys conducted at two-year intervals informed these efforts. The first survey in 2006 benchmarked campers’ awareness of forest threats by invasive species, their evaluations of firewood supplied at and near Wisconsin state parks, and their...
Woodborers in the Agrilus genus (Coleoptera: Buprestidae) pose high invasiveness risk as indicated by the recent invasion and continental spread of emerald ash borer, and the associated threat to ash resources in North America. In that context, development of detection tools for potentially invasive Agrilus spp. is a research priority. Experiments carried out in 2013 in Slovakian beech and poplar forests evaluated the attraction of multiple Agrilus species to green and purple sticky prism traps...

In this film we explore the Wild and Scenic White Salmon River with local experts to learn about how we can all be stewards of this river. The Forest Service seeks to support and educate river users about the best practices to use in order to protect spawning salmon, prevent the spread of invasive species, and maintain a natural and undisturbed shoreline environment. Together we can all be stewards of the Wild and Scenic White Salmon River.

Many invasive plants have been reported as early successional species able to colonize disturbed...
The present-day phytosanitary disasters caused by biological invasions are afflicting urban and peri-urban forest stands worldwide, as well as the varied services they normally provide. In Europe, we are witnessing an alarming situation due to an increasing introduction of infectious diseases and pests. The authors present an up-to-date list of alien microbial pathogens and insect pests affecting urban greening that have been accidentally imported in Italy or that are likely to be introduced. Information...
