An Assessment Of The Competitive Ability Of Oak Species In The Central Hardwood Region Using Both Pre-Harvest Treatment Data And Stem Analysis Techniques, Robert William Edward Quackenbush

Open Access Theses

The density of advance regeneration of oak species has been in decline across the Central Hardwood Region (CHR) for the past 50 years. This phenomenon has been accredited to many different factors, ranging from predation and browse by wildlife, to human induced changes in the environment which include massive clearcutting, land use change from forest to agriculture, and suppression of fires which played an intricate role in the development of oak systems across the CHR. The objectives of this research project were to compare densities of oak advance regeneration across two different environmental gradients within the CHR, in particular the …
