An analysis of stand-level size distributions of decay-affected Norway spruce trees based on harvester data
Räty, Janne; Hietala, Ari Mikko; Breidenbach, Johannes; Astrup, Rasmus Andreas (Peer reviewed; Journal article, 2023-01-05)We studied size distributions of decay-affected Norway spruce trees using cut-to-length harvester data. The harvester data comprised tree-level decay and decay severity recordings from 101 final felling stands, which enabled ... -
Prediction and model-assisted estimation of diameter distributions using Norwegian national forest inventory and airborne laser scanning data
Räty, Janne; Astrup, Rasmus Andreas; Breidenbach, Johannes (Peer reviewed; Journal article, 2021-04-07)Diameter at breast height (DBH) distributions offer valuable information for operational and strategic forest management decisions. We predicted DBH distributions using Norwegian national forest inventory and airborne laser ... -
Prediction of butt rot volume in Norway spruce forest stands using harvester, remotely sensed and environmental data
Räty, Janne; Breidenbach, Johannes; Hauglin, Marius; Astrup, Rasmus Andreas (Peer reviewed; Journal article, 2021-12-25)Butt rot (BR) damage of a tree results from a decay caused by a pathogenic fungus. BR damages associated with Norway spruce (Picea abies [L.] Karst.) account for considerable economic losses in timber production across the ... -
Prediction of forest canopy fuel parameters in managed boreal forests using multispectral and unispectral airborne laser scanning data and aerial images
Maltamo, Matti; Räty, Janne; Korhonen, L.; Kotivuori, E.; Kukkonen, M.; Peltola, H.; Kangas, J.; Packalen, P. (Peer reviewed; Journal article, 2020-09-08)This study evaluated the suitability of different airborne laser scanning (ALS) datasets for the prediction of forest canopy fuel parameters in managed boreal forests in Finland. The ALS data alternatives were leaf-off and ...
