Most of Connecticut appears as a sea of hills swathed with trees when viewed from a high overlook. This seemingly never-changing cloak of trees is, in fact, a constantly changing assemblage of individual trees. Most of our forest, including the tracts discussed in this bulletin, have arisen after harvesting or farm abandonment in the 1800's (Ward and Barsky 2000). The young saplings which grew on those cutover and abandoned lands are now the large, upper canopy trees in our forests today. Because forest growth and development are long-term processes, patterns of forest development have been largely derived using indirect methods such as stand reconstruction and comparing stands of different ages. Indirect methods have outlined the general framework of forest stand dynamics. However, they are of limited utility in providing a specific prediction on the future development of an individual stand of trees with its unique initial composition and disturbance history. Ultimately, forest stand development is the aggregate of the growth, or demise, of many individual trees. Understanding the causal factors that affect the future growth and survival of individual trees will lead to better comprehension of how these factors influence forest succession. This requires a large long-term database with detailed information on individual trees. Fortunately, four large, permanent tracts, the Old-Series plots, were established in young forests (~25-years-old) in central Connecticut in 1926-27. These tracts were reexamined in

“…Similarly, the proportion of oak reproduction was low (10% of all dominant and codominant stems) in 5-17-yearold stands that had originated after clearcutting oak-dominated forests in southern Indiana (Fischer 1987), but the relative density of dominant oak increased over time in those same stands predominantly on the drier, more xeric and less productive stands (Morrissey et al 2008). Heiligmann et al (1985) reported that the proportion of oak in the reproduction following clearcutting ranged from 13% on north slopes to 54% on south slopes 28 years after harvesting oak forests in southeastern Ohio. They concluded that red maple had reduced oak stocking from levels in the original stand on north slopes (site index 66 ft black oak) and that stands on south slopes (site index 63 ft black oak) would remain predominantly oak-hickory in composition.…”

Logging Intensity Impact on Small Oak Seedling Survival and Growth on the Cumberland Plateau in Northeastern Alabama

Ground disturbance caused by forest harvest operations can negatively impact oak regeneration. On the Cumberland Plateau, for successful regeneration, managers often must rely on very small (less than a ft in height) oak advance reproduction that is susceptible to disturbance by harvesting equipment. Furthermore, sites on the Plateau top are often harvested when conditions are too wet to permit operations elsewhere, increasing the risk to small seedlings that may be more easily pulled from the moist soil. This study was designed to assess the effect of unrestricted and restricted harvesting equipment traffic on small oak advance reproduction under a clearcutting prescription. A feller-buncher and grapple skidding were used to harvest sites under "free access," resulting in unrestricted traffic on the sites, or under "trail access," with restricted site traffic. Six hundred eighty-seven oak seedlings were permanently tagged (preharvest); species, height, and basal diameter were recorded and have been remeasured 1, 2, and 8 years postharvest. Fifty-two percent of the tagged seedlings survived after 8 years. The survival rate for seedlings exposed to restricted traffic did not differ from that for seedlings exposed to unrestricted traffic. No evidence of seedlings being pulled out of the ground was observed. After three growing seasons, there was no significant difference in visual site disturbance between the two treatments. After eight growing seasons, the status of the reproduction suggests that little damage was incurred under unrestricted equipment traffic.

Clearcutting, a commonly used silvicultural practice in southeastern Ohio, often results in a forest stand with a different species composition than the parent stand. The time frames during which shifts in species composition occur on different sites are unclear. While some studies have documented species composition at specific points in time, none have attempted to examine differences throughout the first decades of stand development. This study focused on the early successional dynamics of young, mixed-species forests of southeastern Ohio. Species compositions were examined across a chronosequence of sixteen stands that developed following clearcutting. Stand ages ranged from six to 26 years. The sample was limited to dry-mesic hardwood forests on southerly aspects and on soils derived from residuum or colluvium. Across the chronosequence, stand density ranged from 17 636 stems ha -1 at age 6 to 2759 stems ha -1 at age 26, and basal area ranged from 8.2 m 2 ha -1 to 22.1 m 2 ha -1. Clumps comprised a substantial portion of the total stand density and basal area. At age 6-8 years after clearcutting, clumped stems accounted for 35.1% of the density and 48.2% of the basal area. At age 26 years, these proportions were 25.7% and 29.4%, respectively. Clumped stems were significantly larger (p<0.05) than non-clumped stems at each age group except 26 years. Total Quercus spp. density was greatest at age 6-8 years (3386 stems ha-1), and least at age 26 years (581 stems ha-l). When considered as a proportion of the total stand, however, the proportion was relatively stable, averaging 21.3%. However, importance value (IV=[relative density + relative basal areal/2) of Quercus in the upper canopy (dominant and codominant crown classes) was twice as much (72%) at age 26 years compared to age 6-8 years (35%). Quercus prinus L. was the major species across the chronosequence. For all age groups except 18-20 years, Q. prinus IV was the highest of any individual species in the upper canopy, and it ranged from 27 in the youngest stands (6-8 years) to 69 in the oldest stand (26 years). Within the intermediate crown class, the IV of Q. prinus equaled or exceeded those of all other species, except for the 18-20 year age group where it was second to A. rubrum. Quercus alba L. and Quercus velutina Lam. were minor components at age 26 years, although they dominated a comparison sample of six mature stands of the same ecosystem type. Liriodendron tulipifera L. was abundant 6-8 years after clearcutting, but nearly absent at age 26 years. Acer rubrum L. was the major species in both the intermediate and overtopped crown classes throughout the chronosequence. As gaps in the canopy occur, A. rubrum may become a more common species within the dominant-codominant crown class.
