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 2016 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 and in eastern J\u00e4mtland (township of Br\u00e4cke, Ragunda and \u00d6stersund). The inventory in 2016, just like in 2014 and 2015, also includes J\u00e4mtland, compare to the previous years, as a follow-up to the severe winter storms in 2013, which felled a large amount of forest. 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. The results from the inventory should be available for decisions making basis in forestry managements.\n\nThe inventory was stratified by an objective sample of all the National Forest Inventory permanent sample plots in the county of V\u00e4sternorrland and eastern J\u00e4mtland. Included plots within the sample was all older thinning forest and final felling mature forest consisting of at least 7/10 proportion of spruce. 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, 2012, 2013, 2014 and 2015. Measurements of wind-felled trees were included from 2013 onwards and comprises both wind-felled trees newly infested (season 0) with bark beetles and fresh wind-felled trees not infested with bark beetle. In 2016, the variable \u201cincluding stump\u201d is included, which explains if the windfall is a whole tree. This is also explained by the variable \u201dfull length\u201d which also is included in previous years. The dataset consist at plot level of 147 rows with 23 column, at tree level of 466 rows with 12 columns and at wind-felled tree level of 72 rows with 13 columns. \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, 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.\n", "identifier": [{"@type": "PropertyValue", "propertyID": "DOI", "value": "10.5878/thz3-ft06"}, {"@type": "PropertyValue", "name": "principalRegistrationNumber", "propertyID": "https://www.rikstermbanken.se/termposter/1848/diarienummer", "value": "SLU.srh.2024.5.4.I\u00c4-1"}], "citation": {"@type": "CreativeWork", "name": "Wulff, S.
