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 2020 TFDI carried out a sample inventory of the volume Norway spruce (Picea abies) damage by European spruce bark beetle (Ips typographus) in older spruce forest in the region of G\u00f6taland and Svealand excluding Gotland and Dalarna. This as a follow-up to the extremely hot and dry summer in 2018, which resulted in many drought stressed spruce trees that favored the spruce bark beetle. The spruce bark beetle populations, which were already high before, increased rapidly and have in recent years caused extensive damage to spruce in G\u00f6taland och Svealand. The inventory includes both standing infested trees as well as infested wind-felled trees and stumps from felled infested 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 G\u00f6taland and Svealand. Included plots within the sample was all older thinning forest and final felling mature forest consisting of at least 7/10 proportion of spruce. For the selection of plots LPM (local pivotal method, Grafstr\u00f6m et al 2012) is used where the selection was spread based on the geographical position and the spruce volume of the sample plots. The radii of sample plots use for the damage inventory was 25 m, the area which was included for the described site. Other parts of the plot were not included in the inventory. The inventory only includes trees with fresh infestations (season 0) from infestations of the spruce bark beetle. Diameter at breast height was measured on damage trees and wind-felled trees. Diameter on stump from cut trees with fresh damage was measured. The dataset consist at plot level of 653 rows with 30 column, at tree level of 621 rows with 16 columns. The content and scope of the inventory has been developed in consultation with Swedish Forest Agency.\n\nReferences:\nGrafstr\u00f6m, A., Lundstr\u00f6m, N., & Schelin, L. (2012).
