Deterioration of forest ground cover during trampling


, : Deterioration of forest ground cover during trampling. Silva Fennica 11(3): 153-161

Trampling tolerance of the ground cover was studied in Calluna, Vaccinium and Myrtillus site types at the Forest Field Station of the University of Helsinki in central Finland. Study trails were trampled 4-64 times per week for seven weeks in June and July 1972 and 1973.

The effects of graded infusions of atrial natriuretic peptide (ANP) on hemodynamics, renal function, plasma renin activity (PRA) and plasma arginine vasopressin (AVP) were investigated in a two part study in 6 volunteers. Three 30-min iv infusions...
