Spremljanje razvoja sestojev in časovna dinamika propadanja dreves v jelovo-bukovem gozdu

Hladnik, David (author)

Leta 1985 smo s fotointerpretacijskim in terenskim snemanjem integralno analizirali stanje jelovo-bukovih gozdov na visokem krasu. Po delni ponovitvi aerosnemanja v letu 1988 smo oblikovali metodo za spremljanje razvoja sestojev in oceno sprememb poškodovanosti dreves. Rezultati parnih primerjav dreves, opravljenih s fotointerpretacijo infrardečih barvnih letalskih posnetkov in terenskim snemanjem v kontrolnih sestojih, kažejo, da v triletnem obdobju ni bilo velikih sprememb. Prevladovala so drevesa, kjer se poškodovanost ni spremenila, saj smo spremembo stanja krošnje določili pri 11 % jelk in smrek v vzorcu. Razlike med sestoji nakazujejo, da je podoba današnje poškodovanosti tudi posledica preteklega razvoja sestojev in različne intenzivnosti gospodarjenja.

Abstract

In 1985 the condition of forest belonging to plant association Abieti-Fagetum dinaricum on a karst plateau was analysed by photo-interpretation and a field survey. The aerial survey was partially repeated in 1988. Then a method for the observation of the development of stands and for the estimate of changes in damaged trees was designed. The results of a chronological comparative analyses of the same trees, which was performed by photo-interpretation of colour infrared aerial photographs and a field survey in control stands, indicate that there were no considerable changes in the degree of their damage in the three-year period. Changes in crown condition of trees were identified only in 11 % of silver fir and Norway spruce trees of the sample. The differences in the condition of stands indicate that the current damage results partly also from the development of the stands in the past and the degree of intensity of their management.
