Methods
Life forms: trees
Sites: 10
Site area: 0.1
Sampling methods: quadrat
Sample size: 612 individuals
Size min: 5
Basal area: 16.952
Sampling comments: "Three transects were laid down starting from a base of the slope to the end of the vegetation zone in each selected site. The transects were 200 m apart from each other. The quadrats (10x10 m2) were laid down for tree and shrubs in a line running method (Kershaw 1973) along slopes with an interval of 10 m" (apparently meaning that there was one transect in this habitat consisting of 10 quadrats)
