We built on the successful use of canine scent detection for the invasive long-horned beetles Anoplophora glabripennis and Anoplophora chinensis and trained six dogs in detection of EAB. A first test series was performed to evaluate detection accuracy of five of these dogs. Seven different experimental settings were tested under single blind conditions: (1) forest nursery, (2) piles of firewood, (3) firewood on the ground, (4) ash logs on the ground, (5) old urban ash trees, (6) urban forest with ash trees and (7) natural forest with ash trees. In total, 214 positive samples were presented to the dogs, out of which 20 remained undetected. The experiments ascertained sensitivity (correct positives of all positives) ranging from 73.3 to 100 percent and specificity (correct negatives of all negatives) from 88.9 to 99.8 percent in the tested settings. This initial study demonstrates that trained dogs are able to detect EAB scent from sources such as larval galleries in bark/wood, frass, living or dead larvae or dead dry beetles. The numbers of tested dogs and test series were limited, and further studies are needed to confirm the initial results. However, the preliminary findings demonstrate the potential of the method particularly for inspection of wood or plants at entry points.","PeriodicalId":12342,"journal":{"name":"Forestry","volume":"17 1","pages":"326-330"},"PeriodicalIF":2.8,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72653821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vétek, J. Fail, M. Tóth, M. Domingue","doi":"10.1093/forestry/cpz071","DOIUrl":"https://doi.org/10.1093/forestry/cpz071","url":null,"abstract":"Most of the current understanding of the orientation and communication of jewel beetles arose from research on the Asian emerald ash borer (EAB), Agrilus planipennis, which has become one of the most destructive invasive forest insect pests in history following its introduction to North America and European Russia. From a European perspective, a number of jewel beetles have a high invasive risk similar to that of the emerald ash borer, including the potential threat of the bronze birch borer Agrilus anxius, the goldspotted oak borer Agrilus auroguttatus, and the twolined chestnut borer Agrilus bilineatus. Native jewel beetles expanding their geographic range include the cypress jewel beetle Ovalisia festiva and the black-banded oak borer Coraebus florentinus. Other native species are increasing in their importance, including the flathead oak borer Coraebus undatus, the two-spotted oak borer Agrilus biguttatus, the flatheaded beech borer Agrilus viridis and Agrilus cuprescens. Commonly used prism and multi-funnel trap designs and other promising experimental trap designs have been tested and compared in the US and in Europe. One factor considered has been colouration, typically purple and green. Another is olfactory attraction, both to plant volatiles and extracts such as (Z)-3-hexenol, Manuka oil, Phoebe oil and Cubeb oil, and also to pheromones such as (Z)-3-lactone, for emerald ash borer. Field observations have been made of mating and host-finding behaviours of oak buprestids based upon visual stimuli in North America and Europe. By using pinned dead EAB models, visual mating approaches have been observed by males of Agrilus biguttatus, Agrilus sulcicollis and Agrilus angustulus, which is a behaviour similar to that previously observed in EAB. Green plastic-covered branch-traps significantly out-performed other trap designs and caught more Agrilus jewel beetles if an artificial visual decoy that copies a beetle body was included. A higher fidelity decoy offered the same distinctive light-scattering pattern as real resting EAB females and elicited the full sequence of stereotypical male mating flight behaviour of EAB and A. biguttatus from up to 1 m away. An optimization of visual, olfactory and other possible stimuli has likely not yet been achieved. More sophisticated trap designs could lead to more sensitive detection capabilities with increased selectivity.","PeriodicalId":12342,"journal":{"name":"Forestry","volume":"1 1","pages":"254-264"},"PeriodicalIF":2.8,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1093/forestry/cpz071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72534819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vos","doi":"10.1093/forestry/cpz077","DOIUrl":"https://doi.org/10.1093/forestry/cpz077","url":null,"abstract":"\u0000 The European Food Safety Authority (EFSA), by request of the European Commission, develops pest survey cards for pests of relevance for the European Union (EU) member states, summarizing key biological, epidemiological and diagnostic information relevant for the detection and identification of these pests by inspectors and laboratory technicians in the EU member states. For three pilot pests, including emerald ash borer (Agrilus planipennis), detailed guidelines are being prepared for the survey planners in the EU member states. Interaction with experts on the relevant organisms and the member states is needed before and after implementation of the surveys to ensure they are fit for purpose and can be harmonized across the EU. An important feature of the survey cards is the identification of risk factors, to focus the surveys on the most likely areas to find the pest if it is present and thus being able to apply a risk-based surveillance. Since 2014, ash wood and bark (from countries where A. planipennis is known to occur) are subjected to specific requirements laid down in Council Directive 2000/29/EC, the beetle is unlikely to enter the EU via this pathway. However, it cannot fully be excluded that introductions have happened before these requirements came into force, without being detected until now. In addition, the beetle could already be present in new third countries without being noticed yet and thus not regulated. Furthermore, firewood from countries adjacent to Russia (Belarus, Ukraine) is not restricted. The beetle could also hitch-hike to the EU by various means of transport, in particular via highways and railroads. Given the above, surveys should focus on these areas.","PeriodicalId":12342,"journal":{"name":"Forestry","volume":"32 1","pages":"212-219"},"PeriodicalIF":2.8,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87178167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To proactively understand the social impact of an EAB invasion in Europe and the USA, this study analyzed visitors’ preferences and preference heterogeneity for EAB-impacted forest scenarios in Vienna, Austria (n = 510) and Minneapolis, USA (n = 307). An image-based discrete choice experiment with latent-class analysis among on-site completed questionnaires in Vienna indicated four different visitor segments based on trade-offs among biophysical, social and viewscape elements. Within the forested environment, two segments placed greater importance on (bio)physical attributes and two on social aspects. Although all segments preferred a non-impacted ash forest, only one of the four identified the attribute describing EAB impacts and forest management as the most important attribute. Rather, visitor numbers and background viewscapes were more important than EAB impact and management to differentiate landscape preferences for three of the four segments. Differences in preferences were found between the Vienna and Minneapolis samples. Vienna respondents showed a higher preference for more natural conditions, disliked more the initial stage of EAB impact and placed more importance on background viewscapes and visitor numbers. Forest managers and greenspace planners need to consider the entirety of the forested condition, social and visual, for effective management and address that visitors differ in their preferences for all of these conditions.","PeriodicalId":12342,"journal":{"name":"Forestry","volume":"25 1","pages":"225-238"},"PeriodicalIF":2.8,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84821922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A unique interagency team, the Emerging Pests in Colorado (EPIC) Workgroup, was formed in 2009 to address the immediate threat from Thousand Cankers Disease (TCD) of walnut and to plan for the arrival of other invasive urban forest pests to Colorado. When the emerald ash borer (Agrilus planipennis Fairmaire) (EAB) was detected in Boulder, Colorado in 2013, it marked the westernmost occurrence of EAB in the US, threatening millions of planted and naturalized ash trees representing over 25 percent of the tree canopy throughout Colorado’s urban and riparian forests. The detection in Boulder prompted the development of a second multi-agency group, the Colorado EAB Response Team (CORT). The preparedness and established working relationships between stakeholders and responsible authorities allowed for a quick, decisive and unified response. We review as a case study: (1) the formation and history of collaborative interagency groups in Colorado; (2) how the interagency collaborative planning and post-detection EAB response have supported community forestry programmes throughout the state; (3) development of the post-detection EAB management plan and economics behind the strategy in Boulder, Colorado; and (4) the proactive EAB planning and outreach efforts underway in Denver, Colorado.","PeriodicalId":12342,"journal":{"name":"Forestry","volume":"47 1","pages":"239-253"},"PeriodicalIF":2.8,"publicationDate":"2020-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74713736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Finnish MELA simulator was used to generate multiple treatment schedules over time at the management unit level – each treatment schedule providing unique estimates of extracted wood volumes by different assortment categories for each time period. The J linear programming (LP) software was used to analyse different regional forest strategies in terms of wood supply and transportation costs to multiple market destinations. The analysis revealed clear differences both in wood flows and forest resources between strategies maximizing wood supply or optimizing wood supply to market destinations. In addition, the wood flows appeared responsive to new mill and increased demand. Further, the changes in factory price had a heavier impact on pulpwood supply than on sawlog supply. The same methodology can be applied for analysing the impact of new factories on wood flows from forest to factories and between factories or to support forest enterprises in planning their wood supply over multiple time periods and multiple destinations.","PeriodicalId":12342,"journal":{"name":"Forestry","volume":"12 1","pages":"163-177"},"PeriodicalIF":2.8,"publicationDate":"2020-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77117685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
