Growth Response of Tamarack to Ditching
Forest drainage systems have been used effectively to remove excess water from poorly drained forest soils and to increase site productivity. A study was conducted in northern Michigan to determine the effects of a drainage ditch on the productivity of tamarack 65 years after ditching. Site index increased 55% and average diameter increased 145% within 5 m of the ditch. There was no apparent effect of ditching on site index beyond 80 m from the ditch or diameter beyond 20 m. North. J. Appl. For. 6:107-109, September 1989.
