Institute of Paper Chemistry Field Trials on the Ripco Industrial Forest

The Institute of Paper Chemistry has several field plots on the Ripco Industrial Forest of the Rhinelander Paper Company near Eagle River, Wis. These plots include trials of some larch species and hybrids, and field tests of various aspen polyploids, hybrids, and other selected material. There has been renewed interest in larch as a source of rapidly growing pulpwood. The fast growth of certain larch species and hybrids (especially Larix eurolepis) has been widely recognized, and polyploidy in larch is also an approach that looks promising. The materials planted in this area are part of a preliminary trial established to acquaint us with the proper methods of handling larch seedlings, check the suitability of several species of larch for use in this area of Wisconsin, and serve as a source of material for future experimental work with larch. Two additional larch species trials were established this past spring employing eight additional sources of material.
