This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of northern red oak (Quercus rubra L.) in the oak-hickory forest type and its growth and development into the overstory is of great concern due to the value of this species as a source of forest products and mast for wildlife. There is a general consensus that rapid oak seedling height growth occurs above certain threshold levels of light, soil moisture, and nutrients. If these specific levels and the relative importance of competition between northern red oak (NRO) seedlings and other individual plant species can be determined, then the implementation of more precise management practices that promote rapid NRO seedling height growth and more cost-efficient competition control treatments could be developed. The detection of genetic family differences among artificially regenerated NRO seedlings could also have future applications in advancing the competitive ability of NRO in the field. This study had three objectives. The first objective was to identify light, soil moisture, and nutrient levels in the immediate vicinity of NRO seedlings that lead to rapid height growth. The second objective was to establish which plant species are the most important competitors limiting these resources and thus the height growth and survival of NRO seedlings. The third objective was to identify potential genetic family differences among the NRO seedlings used in this experiment. This study was conducted on moderately productive sites in mature oak-hickory forests on the University of Tennessee Forestry Experiment Station at Oak Ridge in east Tennessee. A randomized complete block design was used, and the dependent variables were height growth and percent survival for all NRO seedlings. Six treatments were ...

Lind-Riehl and published by . This book was released on 2014 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest trees, like oaks, rely on high levels of genetic variation to adapt to varying environmental conditions. Thus, genetic variation and its distribution are important for the long-term survival and adaptability of oak populations. Climate change is projected to lead to increased drought and fire events as well as a northward migration of tree species, including oaks. Additionally, decline in oak regeneration has become increasingly concerning since it may lead to decreased gene flow and increased inbreeding levels. This will in turn lead to lowered levels of genetic diversity, negatively affecting the growth and survival of populations. At the same time, populations at the species' distribution edge, like those in this study, could possess important stores of genetic diversity and adaptive potential, while also being vulnerable to climatic or anthropogenic changes. A survey of the level and distribution of genetic variation and identification of potentially adaptive genes is needed since adaptive genetic variation is essential for their long-term survival.

Download or read book Regeneration of Red Oak Quercus Rubra L Using Shelterwood Systems written by Dan Dey and published by Sault Ste. Marie : Ontario Ministry of Natural Resources. This book was released on 1996 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to review the scientific literature on red oak biology and silviculture as it pertains to the use of shelterwood systems in oak regeneration and management. Sections of the report describe oak ecophysiology and succession; growth characteristics; environmental requirements (light, water, nutrients, temperature) and response to stress (pests, competition); and oak regeneration ecology (acorn production and dispersal, seeding and germination requirements, artificial regeneration). The final section reviews oak management by shelterwood systems, including prescriptions for residual overstory, control of understory vegetation, stocking targets, and final overstory removal.

This book was released on 2016 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this project was to determine whether the eastern gray squirrel is a directed disperser of the northern red oak. Under directed dispersal, animals preferentially move seeds to microsites with characteristics that favor seedling establishment. Squirrel-chosen cache sites were located by providing squirrels with tagged red oak acorns. We then collected data on a suite of microsite characteristics at squirrel-chosen sites and at randomly-chosen sites. We observed that squirrel chosen sites are drier, have less wood debris cover around them, and are closer to trees than at random sites. There were no differences between cache and random sites with regards to canopy cover, or the cover of leaves/needles, herbaceous plants, or woody plants near the sites. We then planted fresh red oak, white oak, and chestnut seeds at cache and random sites. These sites will be reexamined in the spring in order to compare rates of emergence at squirrel-chosen and random sites.
