An annual monitoring of the most important sources of forest damage is carried out by the Swedish National Forest inventory (NFI). Although the Swedish NFI is an objective and uniform inventory of forest damage in Swedish forests at national and regional scales, less common or less widespread occurrences of forests pests and pathogens are difficult to survey solely through large-scale monitoring programmes. There is a need for complementary inventories to facilitate timely delivery of relevant information.\n\nThus Target-tailored forest damage inventories (TFDI) aiming at providing data for operational decisions making at local level, and linked to specific damage events were introduced. TFDI\u2019s are developed to give rapid response to requested information of specific damage outbreaks. The TFDIs are carried out in limited and concentrated samples, with flexible but robust methods and design. The data collected in the TFDI shall also be of such quality that it can be useful in research.\n\nDuring 2013 TFDI carried out a sample inventory of the volume Norway spruce (Picea abies) damage by bark beetles, Four-eyed spruce bark beetle (Polygrapus poligraphus) and/or European spruce bark beetle (Ips typographus) in older spruce forest in the county of V\u00e4sternorrland. The inventory included both standing and wind-felled trees. The purpose of the inventory was to estimate the volume Norway spruce damage by the given bark beetles, but also to highlight geographical distribution and the appearance of the damage in different forest sites.\n\nThe inventory was stratified by an objective sample of all the National Forest Inventory permanent sample plots in the county of V\u00e4sternorrland. Included plots within the sample was older thinning forest and final felling mature forest consisting of at least 7/10 spruce and a lesser proportion of forest with lesser share of spruce or younger thinning forest. The radii of sample plots use for the damage inventory was 25 m. Diameter at breast height was measured on damage trees and wind-felled trees. Diameter on stump from cut trees with fresh damage was measured. Furthermore species of bark beetle and age of damage was recorded. The inventory was carried out in the same way as in 2011 and 2012, but with the addition that damaged wind-felled trees were included. During 2013 also the variable Edge time was introduced, i. e. when a stand edge within 25 m from plot center occurred. In total 93 plots and 330 trees and 118 wind-felled trees was measured. \n\nSome assessed and used variables:\n\nAt sample plot level:\nPlot area measured\nThe proportion of spruce at the sample plot\nMaturity class \n\nAt tree level:\nIs the tree dead or alive?\nPosition of tree \u2013 standing, wind thrown, stump\nDiameter at breast height\nWhich species of bark beetle has attacked the tree?\nWhich season did the damage occur?\nTree volume\n\nAt wind-felled tree level:\nDiameter at breast height\nIs the tree infested by bark beetle?\nWhich species of bark beetle has attacked the tree?\nWhich season did the tree fell?\nTree volume\n\nSee the document \"Data_description\" for more detailed information. As additional documentation, field instructions for the inventories are also provided, both for the specific inventory and for the National Forest Inventory (NFI). An English version of the National Forest Inventory field instruction is available for year 2021 only, which is why this is included here.", "@language": "en"}, {"@value": "Med hj\u00e4lp av ett flexibelt inventeringskoncept inriktat p\u00e5 skogsskador kan Sveriges Lantbruksuniversitet (SLU) inom milj\u00f6analysprogrammet Skog f\u00f6lja upp och presentera information om olika slags skogsskador. En \u00e5rlig uppf\u00f6ljning av stora skadeutbrott i v\u00e5ra svenska skogar sker via Riksskogstaxeringens (RT) objektiva inventeringar. Men trots att vi h\u00e4r f\u00e5r en kontinuerlig uppf\u00f6ljning av de viktigaste skadesymptomen saknas ofta m\u00f6jligheten att p\u00e5 ett l\u00e4mpligt s\u00e4tt f\u00f6lja upp regionala skadeutbrott. \n\nMed fler f\u00f6rv\u00e4ntade skadeutbrott i klimatf\u00f6r\u00e4ndringarnas sp\u00e5r finns ett stigande behov av regional information med god precision. F\u00f6r att effektivisera \u00f6vervakningen av skogsskador har Nationell Riktad Skogsskadeinventering (NRS) introducerats med skr\u00e4ddarsydda inventeringar riktade mot enskilda skadeg\u00f6rares utbrott. NRS ska kunna leverera underlag om en skadas status och omfattning, s\u00e5 att specifika operativa beslut kan fattas. D\u00e4rf\u00f6r kan inriktningen av inventeringen variera beroende p\u00e5 vilka skador som f\u00f6r tillf\u00e4llet \u00e4r mest relevanta och f\u00f6r vilka skador det finns uttalade behov av information. Inventeringen ska vara \u00e5tg\u00e4rdsorienterad och snabbt kunna leverera resultat. Data som samlas in i NRS ska ocks\u00e5 vara av s\u00e5dan kvalitet att de kan vara anv\u00e4ndbara inom forskningen.\n\nUnder 2013 har inom NRS genomf\u00f6rts en stickprovsinventering utav barkborreangrepp av dubbel\u00f6gad bastborre (Polygrapus poligraphus) och/eller granbarkborre (Ips typographus) i \u00e4ldre granskog i V\u00e4sternorrlands l\u00e4n. Inventeringen omfattade b\u00e5de st\u00e5ende angripna tr\u00e4d och vindf\u00e4llen. Syftet med inventeringen var att skatta volym angripen gran, men ocks\u00e5 att belysa den geografiska f\u00f6rdelningen samt skadornas upptr\u00e4dande p\u00e5 olika typer av mark och i olika typer av f\u00f6ryngringar. Resultaten fr\u00e5n inventeringen ska kunna fungera som beslutsunderlag till m\u00f6jliga sk\u00f6tsel\u00e5tg\u00e4rder.\n\nInventeringen stratifierades genom ett objektivt urval av Riksskogstaxeringens alla permanenta provytor i V\u00e4sternorrlands l\u00e4n. I urvalet ingick, alla ytor i \u00e4ldre gallrings eller slutavverkningsmogen granskog (\u2265 7/10 gran),  25 % av ytor i motsvarande \u00e5lder men med en granandel p\u00e5 3 \u2013 6/10 och 10 % av alla ytor i yngre gallringsskog med en granandel p\u00e5 minst 3/10. Inventeringen utf\u00f6rdes p\u00e5 den del av en cirkelyta med 25 m radie, vars yta ingick i det beskrivna best\u00e5ndet. Andra delar av cirkelytan ingick inte i inventeringen. P\u00e5 angripna st\u00e5ende tr\u00e4d och vindf\u00e4llda tr\u00e4d har br\u00f6sth\u00f6jdsdiameter uppm\u00e4tts. P\u00e5 stubbar efter avverkade tr\u00e4d med f\u00e4rska angrepp har stubbdiameter uppm\u00e4tts. F\u00f6rutom diameter har ocks\u00e5 barkborreart och \u00e5lder p\u00e5 angreppen angetts. Inventeringen har genomf\u00f6rts p\u00e5 samma s\u00e4tt som under 2011 och 2012, men med till\u00e4gget att angripna vindf\u00e4llda tr\u00e4d \u00e4r inkluderade.
