The aim of the study was to assess the changes occurring in the forests of the Kłodzko Region in the recent period (2001−2017), with particular emphasis on the species composition of the stands, their share in age classes and the structure of harvested timber, including live trees, deadwood, wind−broken and wind−fallen trees. The Kłodzko Region located in the Sudety Mountains (SW Poland) covers the...
The objective of the study was to recognise the species composition of bats in two forest stands that differ in terms of habitat type and age class. The study was carried out in the Niepołomicka Forest (southern Poland). An ultrasound ‘time−expansion’ processing system with Pettersson D240× detector was used to identify bat species by their echolocation signals employing SonoBat v.2.9.7 software to...
The review focuses on use of airborne hyperspectral imagery in forest species classification. Studies mentioned in the review concern hyperspectral image classification with use of various methods. Only research, where study area is located in Europe or North America were selected. Articles were reviewed with respect to used pre−processing methods, methods of feature selection or feature extraction,...
Carabid beetles are frequently used as the environment condition indicators. Main purpose of this study was to test if community structure parameters of carabids indicate the stress intensity of heavy metal contamination in the soil of temperate forests. Three geographic regions in Europe differing in both degree of accumulation of heavy metals and its quality were chosen. In Olkusz (southern Poland)...
We used hyperspectral data from APEX scanner (288 spectral bands in 380−2500 nm spectral range; 3,5 m spatial resolution) to classify five tree species occurring in the area of Mt. Chojnik in the Karkonoski National Park (south−western Poland). Data used to delimit learning and veri− fication polygons were acquired during field research in August 2013, when ground truth polygons were acquired using...
