The Influence of Stational Factors over Indicator Species

Abstract. In this paper, the direct links between the herbaceous vegetation and soil pH has been analyzed, also taking in consideration other stational elements. For a more relevant result, the study was conducted in a secular forest because the natural balance and processes are way superior to the ones of a small planted forest. In order to achieve the proposed objectives, 136 circular sample surfaces, with a radius of 12,62 m, were created after a grid reference, 50 m apart, on the entire 35B, LIP VIII, Slătioara, Stulpicani forestry, Forestry Department Suceava, landscape surface. Otherwise, on this surface, the bonds between the information provided by the indicator species and soil pH, altitude and climate factors are not the usual ones. They are the ones from the North East side of the studied terrain, on a cone shaped micro-form of landscape where according to the relative low altitude the reactions should have been registered as having a more reduced acid pH. An important phenomenon that was observed in this place is cavitation. The influences of the phenomenons such as cavitation must be studied more extensive in the future, because they could have a direct effect, unknown yet, over the local vegetation
