Item type:Наукова стаття, Monitoring climate change dynamics in protected areas of Volyn Region(2026) Fedoniuk, Vitalina; Ivantsiv, Yaroslava; Ivantsiv, Vasul; Zhadko, OksanaNature reserves and national parks constitute the most valuable part of the nature reserve fund and are key elements of the ecological network. In recent decades, their ecosystems have been significantly affected by climate change. Research into the manifestations of climate change within protected areas makes it possible to develop effective adaptation mechanisms and identify ways to prevent or minimize negative impacts on biota, particularly rare and vulnerable species. The aim of the work is to conduct a comparative analysis of the dynamics of climate indicators in the Cheremsky Nature Reserve, Shatsk National Nature Park, Kivertsi National Nature Park “Tsumanska Pushcha” and Prypiat-Stokhid National Nature Park, to study regional manifestations of climate change, its possible impact on biodiversity, and to visualize the results. We compared climatic indicators in the four largest protected areas of Volyn during 2014-2024 with each other and with the climatic norm; assessed the possible impact of climate change on biota; developed two interactive maps to visualize changes in temperature, humidity, precipitation, cloud cover, snow cover, and atmospheric phenomena.Item type:Наукова стаття, Spatial analysis of wildfire occurrence in the Emerald Network sites of Volyn and Zhytomyr Polissia (2012-2024)(2025) Fedoniuk, Mykola; Kovalchuk, Ivan; Fesyuk, Vasyl; Fedoniuk, Vitalina; Zhadko, OksanaThe paper analyzes the spatial and temporal distribution of wildfires over a 13-year period in 36 sites of the Emerald Network located within the Ukrainian Polissia region. Materials of remotely sensed data from MODIS satellites provided by the European Forest Fire Information System (EFFIS) were used. The number of hotspots in each of the Emerald Network sites was calculated, and the density of fires was determined both in individual sites and for the entire territory. The temporal distribution of wildfires occurrence was analyzed, and the years and seasons of the maximum and minimum number of fires were identified. The area of burned land was estimated. The Emerald Network sites were ranked according to the obtained quantitative indicators. The locations and types of ecosystems most and least affected by fires were identified. It was established that most of the studied Emerald Network sites are characterized by a lower frequency of wildfires occurrence compared to the average values for the region.Item type:Наукова стаття, Monitoring of climate changes and the state of natural complexes of the Cheremsky Nature Reserve(2023) Fedoniuk, Vitalina; Zhadko, Оksana; Vovk, Оleksandr; Fedoniuk, Mykola; Ivantsiv, VasulIn recent decades, global climate changes have resulted in a range of regional climatic processes and phenomena, exerting significant impacts on the natural complexes within nature conservation areas, protected objects, and elements of the ecological network. The study of these effects is highly pertinent to the territories and natural systems encompassed by the Cheremsky Nature Reserve, a particularly valuable nature conservation complex in Northwestern Polissya. Our analysis was based on meteorological data from the nearest weather station, complemented by remote sensing techniques examining vegetation and water indices over the 5-year period. This examination revealed several notable deviations from climatic norms, including: an increase in annual and maximum air temperatures by 2.0°C and minimum temperatures by 1.0-1.5°C, an increase in annual precipitation by 5-6%, a drastic reduction in snow cover duration by 2-2.5 times, a decrease in the number of days with precipitation by 10-17%, a substantial increase in the number of days with thunderstorms. These findings suggest a negative impact on natural complexes, primarily due to an increase in evaporation from the active surface and a corresponding decrease in the humidity coefficient by 20-25%. Additionally, our study revealed the interrelation between vegetation processes and the dynamics of climatic indicators.
