Abstract:Na območju Krakovskega pragozdnega rezervata smo ocenjevali fenološke razlike prevladujočih drevesnih vrst na podlagi satelitskih posnetkov Sentinel-2. Ocenili smo vrednosti normiranega diferencialnega vegetacijskega indeksa NDVI v obdobju med 29. marcem in 5. oktobrom 2017. Razlike v fenološkem razvoju doba, belega gabra in črne jelše smo potrdili s štirimi zaporednimi satelitskimi posnetki v aprilu in maju. Ocene NDVI iz tretje dekade aprila, druge in tretje dekade v maju 2017 je bilo mogoče uporabiti za razlikovanje razvoja najzgodnej- šega olistanja belega gabra, kasnejšega olistanja doba in in poznega končnega olistanja črne jelše. S primerjavo vzorčnih ploskev v dobovih sestojih je mogoče sklepati o mikrorastiščnih razlikah, ki vplivajo tudi na oceno vegetacijskih indeksov.

Title:Estimation of the leaf-out phenology of trees in a floodplain forest using satellite-based data
Abstract:In Krakovo virgin forest reserve we assessed the phenological differences of the prevailing tree species on the basis of the Sentinel-2 satellite imagery. We assessed the values of the normalized difference vegetation index NDVI in the period from March 29 to October 5, 2017. The differences in the phenological development of pedunculate oak, common hornbeam and black alder were confirmed with four consecutive satellite images in April and May. NVDI assessment from the third decade in April, second and third decade in May 2017 could be used for differentiating the development of the earliest leaf-out of common hornbeam, subsequent leaf-out of pedunculate oak and late final leaf-out of black alder. Comparison of sampling plots in pedunculate oak stands enables us to conclude about the micro site differences that also affect the assessment of vegetation indices.
