Regeneration Methods to Reduce Pine Weevil Damage to Conifer Seedlings
Regeneration Methods to Reduce Pine Weevil Damage to Conifer Seedlings Magnus Petersson Southern Swedish Forest Research Centre Alnarp Doctoral thesis Swedish University of Agricultural Sciences Alnarp 2004 Acta Universitatis Agriculturae Sueciae Silvestria 330 ISSN: 1401-6230 ISBN: 91 576 6714 4 © 2004 Magnus Petersson, Alnarp Tryck: SLU Service/Repro, Alnarp 2004 Abstract Petersson, M. 2004. Regeneration methods to reduce pine weevil damage to conifer seedlings. ISSN: 1401-6230, ISBN: 91 576 6714 4 Damage caused by the adult pine weevil Hylobius abietis (L.) (Coleoptera, Curculionidae) can be a major problem when regenerating with conifer seedlings in large parts of Europe. Weevils feeding on the stem bark of newly planted seedlings often cause high mortality in the first three to five years after planting following clear-cutting. The aims of the work underlying this thesis were to obtain more knowledge about the effects of selected regeneration methods (scarification, shelterwoods, and feeding barriers) that can reduce pine weevil damage to enable more effective counter-measures to be designed. Field experiments were performed in south central Sweden to study pine weevil damage amongst planted Norway spruce (Picea abies (L.) H. Karst.) seedlings. The reduction of pine weevil damage by scarification, shelterwood and feeding barriers can be combined to obtain an additive effect. When all three methods were used simultaneously, mortality due to pine weevil damage was reduced to less than 10%. Two main types of feeding barriers were studied: coatings applied directly to the bark of the seedlings, and shields preventing the pine weevil from reaching the seedlings. It was concluded that the most efficient type of feeding barrier, reduced mortality caused by pine weevil about equally well as insecticide treatment, whereas other types were less effective. -

A brief review of the history of investigation of the weevil fauna (Coleoptera: Curculionoidea) on the territory of Serbia and Montenegro is given. The fauna is compared with that of the World and Europe. Key words. Rhynchophorous beetles, Coleoptera, Curculionoidea, fauna, Serbia and Montenegro. Краткая характеристика мировой и европейской фаун долгоносиков Отряд жесткокрылые, или жуки (Coleoptera), насчитывает более полумиллиона видов, что составляет почти треть животного мира (Lekić, Mihajlović, 1970). По некоторым новым оценкам, число видов жуков на Земле может составлять около одного, а то и двух миллионов. Бόльшая часть видов – обитатели суши, где они населяют самые разнообразные биотопы от пустынь через джунгли, леса умеренного пояса, травянистые сообщества, болота и другие ландшафты до самых высоких горных вершин. Только в морях жуков почти нет (если не считать водных жуков в опрес- ненных прибрежных участках). По-разному оценивается число видов долгоносиков (Curculionoidea) в мировой фауне, по- скольку они в разных частях света изучены не с одинаковой полнотой. -

Vermont Forests 2017
United States Department of Agriculture Vermont Forests 2017 Forest Service Northern Resource Bulletin Publication Date Research Station NRS-120 March 2020 Abstract The second full remeasurement of the annual inventory of the forests of Vermont was completed in 2017 and covers nearly 4.5 million acres of forest land, with an average volume of over 2,300 cubic feet per acre. The data in this report are based on 1,125 plots located across Vermont. Forest land is dominated by the maple/beech/birch forest-type group, which occupies 71 percent of total forest land area. Of the forest land, 70 percent consists of large diameter trees, 23 percent contains medium diameter trees, and 7 percent contains small diameter trees. The volume of growing stock on timberland has continued to increase since the 1980s and currently totals nearly 9 billion cubic feet. The average annual net growth of growing stock on timberland from 2012 to 2017 was nearly 160 million cubic feet per year. Additional information is presented on forest attributes, land use change, carbon, timber products, species composition, regeneration, and forest health. Sets of supplemental tables are available online at https://doi.org/10.2737/NRS-RB-120 and contain summaries of quality assurance data and a core set of estimates for a variety of forest resources.

Michigan Forest Ecosystem Vulnerability Assessment and Synthesis: a Report from the Northwoods Climate Change Response Framework Project
United States Department of Agriculture Michigan Forest Ecosystem Vulnerability Assessment and Synthesis: A Report from the Northwoods Climate Change Response Framework Project Forest Northern General Technical Service Research Station Report NRS-129 March 2014 ABSTRACT The forests in northern Michigan will be affected directly and indirectly by changing climate during the 21st century. This assessment evaluates the vulnerability of forest ecosystems in the eastern Upper Peninsula and northern Lower Peninsula of Michigan under a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and described a range of projected future climates. This information was used to parameterize and run multiple vegetation impact models, which provided a range of potential vegetative responses to climate. Finally, we brought these results before a multidisciplinary panel of scientists and land managers familiar with Michigan forests to assess ecosystem vulnerability through a formal consensus-based expert elicitation process. The summary of the contemporary landscape identifies major forest trends and stressors currently threatening forests in the region. Observed trends in climate over the past century reveal that precipitation increased in the area, particularly in summer and fall, and that daily maximum temperatures increased, particularly in winter. Projected climate trends for the next 100 years using downscaled global climate model data indicate a potential increase in mean annual temperature of 2.2 to 8.1 °F for the assessment area. Projections for precipitation indicate an increase in winter and spring precipitation, and summer and fall precipitation projections vary by scenario. We identified potential impacts on forests by incorporating these climate projections into three forest impact models (Tree Atlas, LANDIS-II, and PnET-CN). -
The Case of the Deodar Weevil
What Is Attacking My Pine? The Case of the Deodar Weevil Many pine owners are able to identify the damage caused by southern pine beetles (Dendroctonus frontalis) (SPB) or Ips engraver beetles (Ips spp.). Many, however, have never heard of the deodar weevil (Pissodes nemorensis) unless they have experienced an outbreak on their property. Fortunately, this native insect leaves very distinctive signs and tree symptoms that landowners can use to survey their pines for this pest. Deodar weevils are native insects that attack a variety of conifers, such as all loblolly (Pinus taeda), longleaf (P. palustris), shortleaf (P. echinata), and slash (P. elliottii). In response to deodar weevils and other insects, pines have developed natural defenses which effectively prevent attacks when trees are healthy and growing rapidly. During most years, deodar weevils only attack a few suppressed, unhealthy trees scattered in well-managed plantations. As such, the deodar weevil is not an insect that regularly alters traditional pine management. Pine owners should be mindful of the risk deodar weevils can pose under certain environmental conditions. Figure 1. An outbreak of deodar weevils and Ips engraver beetles occurred Being able to differentiate deodar damage from that of other in 2015. Together, these pests contributed to widespread pine mortality in central Mississippi (brown tops). Landsat image via Google Maps, Copiah insect pests is important for proper stand management. County, 2016. Rapid identification of a deodar outbreak can help guide post-attack management treatments and reduce future damage. The goal of this publication is to help forest of spread occurs during the fall when fungus-carrying landowners identify deodar weevils and develop a plan to weevils bore into trees to reproduce.
