Influences of Forestry on Water Courses

By using the principle of calibration period and reference area, the following measures normally practiced in Finnish forestry are studied:

ditch network maintenance on organic soils drained for forestry
fertilization of peatland forests
clearcutting and site preparation on mineral soils
clearcutting and site preparation on peatland sites

The project is divided into seven subprojects, all of which record runoff and take runoff water samples. In one subproject, also ground water is sampled. 1995 is the major year of reporting.
