Rezumat

Impactul schimbărilor climatice asupra potențialului recreativ al pădurilor din Ocolul Silvic Pătrăuți se poate evalua prin utilizarea modelului dinamic la nivel de peisaj LandClim. Analiza acoperă o perioadă de 100 de ani (2020-2120) sub trei scenarii climatice (RCP2.6, RCP4.5, RCP8.5) și două tipuri de gestionare forestieră. Indicele de Recreere (IR) a fost calculat pe baza a șase indicatori: bogăția speciilor, heterogenitatea diametrelor și înălțimilor, densitatea arboretului și regenerării, precum și cantitatea de lemn mort. Rezultatele arată că potențialul recreativ optim se situează la altitudini de 350-450 m, unde IR atinge valori maxime de 0,380, datorită echilibrului între bogăţia speciilor și structura dimensională complexă. În scenariul optimist RCP2.6, potențialul recreativ crește constant, în special în absența gestionării (NOM). Scenariul moderat RCP4.5 menține valori acceptabile până în 2070, urmate de un declin abrupt. În scenariul pesimist RCP8.5, potențialul recreativ devine aproape nul după 2090 din cauza uscării masive a arborilor provocate de secetă extremă și temperaturi crescute. Simulările evidențiază necesitatea adaptării strategiilor de gestionare și ponderare a indicatorilor incluşi în IR prin sondaje locale, precum și includerea perturbărilor naturale în simulările viitoare pentru o evaluare realistă a dinamicii pădurilor în contextul schimbărilor climatice.
