Bottom land hardwood sites are known to have some of the most productive forest soils, and species richness tends to be high on these sites. Due to high species richness and associated stand stratification, competition control is often essential to hardwood regeneration efforts. Midstory injection has long been recognized as a viable and cost effective method in controlling undesirable stems (Williston and others 1976). Peairs and others (2004) reported that midstory/understory control treatment increased regeneration of desirable hardwood species such as oaks. Lockhart and others reported that advanced cherry bark oak (Quercus pagoda Raf.) regeneration released from midstory competition were 76.2-103.6 cm taller than non-released seedlings nine years after treatment.
