A survey was carried out in 2013-2019 on the life cycle of the bud blight Gemmamyces piceae (Borthw.) Casagrande and the trend assessment in the infestation of the Colorado blue spruce Picea pungens Engelm. stands. Four ecologically different plots were chosen in the Fláje region in the Eastern part of the Krušné hory Mountains. The pycnidia were formed at the beginning of June on buds infested the previous year. Later, in the second half of June, they formed on the spring attack buds. Conidia occurred in the first week of July on the buds of the old infestation, or later in the case of the spring attack buds, in the middle of July....

The bark beetle, Pityogenes scitus Blandford, 1893 (Coleoptera: Curculionidae: Scolytinae) is one of the main pests in Pinus wallichiana A.B. Jackson, 1938 (Pinaceae) stands, and it has also been found on other Oriental Pinaceae species. This pest is aggressive and has caused significant loss of host trees, but little is known of its biology and ecology. Based on the field and laboratory observations, this study describes the detailed bioecology of P. scitus. This beetle pest overwinters in larval stage on blue pine (P. wallichiana) trees in Kashmir. After emergence, the adults fly to suitable trees and undergo maturation...

Modern geospatial technologies and permanently updated wildfire monitoring datasets are the basis of improving forest firefighting on different administrative scales. One of the tasks is to use the spatial representation of forest fire locations during the fire season and offer timely suitable technical options for accessing them. We developed a GIS technology to create forest fire ground access routes for special firefighting vehicles moving from a ground firefighting base (fire-chemical station) to the place of the forest fire detection; the technology includes a statistical and geospatial accessibility analysis of the routes. The key data are a...

The present study offers the results of the spectral characteristics, calculated vegetative indices and biophysical parameters of pine stands of the Northern Steppe of Ukraine region obtained using Sentinel-2 data. For the development of regression models with the prediction of the biomass of pine forests using the obtained spectral characteristics, we used the results of the assessment of the aboveground biomass by the method of field surveys. The results revealed the highest correlation relations between the parameters of the general and trunk biomass with the normalised difference vegetation index (NDVI) and transformed vegetation index...
