This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintenance of oak species and a lack of oak regeneration are major silvicultural problems in many upland oak forests of the Eastern United States. Advance oak regeneration where present generally is small and lacks vigor. As a result, artificial regeneration is sometimes used, but planted oak seedlings usually do not grow well. Plastic tree shelters have been used to protect planted and natural oak seedlings from deer browsing and to promote seedling height growth and survival. This study examined the growth and survival of planted and natural red oak seedlings and seedlings from planted acorns within translucent tree shelters, fences, and unprotected controls with and without herbicide application under a shelterwood seed-cut stand. After 2 years, surviving control planted seedlings were significantly shorter than those protected by tree shelters and fences. The average height of seedlings planted within tree shelters and fences was 0.88 foot and was not significantly different. Planted control seedlings were shorter after the second year than the first, suggesting that these unprotected seedlings had been browsed by deer. The best survival of planted seedlings was inside the fences, with and without herbicide. Survival in shelters was 82 percent when herbicide was used and 40 percent without herbicide, probably due to low light intensity. Survival of planted control seedlings was unsatisfactory whether or not herbicide was applied, likely the result of browsing. Only 16 percent of the acorns planted within shelters produced seedlings and none grew outside of shelters. Small mammals destroyed most planted acorns. Natural seedlings grew little and their height inside and outside of shelters was not different from that of planted seedlings. Recommendations based on these results should improve results when tree shelters are used.

Book excerpt: Native plants are a foundation of ecological function, affecting soil conservation, wildlife habitat, plant communities, invasive species, and water quality. Establishing locally-adapted, self-sustaining plant communities can also support transportation goals for safety and efficiency. Past obstacles to establishing native plant communities on roadsides have been technical, informational, and organizational. Effective strategies and practical techniques for revegetating the disturbed conditions with limited resources must be made available to practitioners. Multiple disciplines, ranging from engineering to soil science, ecology, botany, and wildlife science, must be able to work cooperatively, not in isolation. This report offers an integrated approach to facilitate the successful establishment of native plants along roadsides and other areas of disturbance associated with road modifications. It guides readers through a comprehensive process of: 1) initiating, 2) planning, 3) implementing, and 4) monitoring a roadside revegetating project with native plants.

Available in PDF, EPUB and Kindle. Book excerpt: This publication sets out a comprehensive review of tree root biology and covers a broad range of practical issues that need to be considered in order to grow trees successfully in our towns and cities and to realise the significant benefits they provide in built environments. Topics covered include: soil condition and roots; improving tree root growth in urban soils; water supply and drought amelioration for amenity trees; coping with soil contamination; protecting trees during excavation and good trenching practice; control of damage to tree roots on construction sites; tree root damage to buildings and pavements, sewers, drains and pipes; research needs and sustainability issues.

This book was released on 2021-09-24 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural Resources Conservation and Advances for Sustainability addresses the latest challenges associated with the management and conservation of natural resources. It presents interdisciplinary approaches to promote advances in solving these challenges. By examining what has already been done and analyzing it in the context of what still needs to be done, particularly in the context of latest technologies and sustainability, the book helps to identify ideal methods for natural resource management and conservation. Each chapter begins with a graphical abstract and presents complicated or detailed content in the form of figures or tables. In addition, the book compares the latest techniques with conventional techniques and troubleshoots conventional methods with modifications, making it a practical resource for researchers in environmental science and natural resource management. Discusses the pros and cons of past and current endeavors related to natural resource management Presents recent technologies and methods for management and conservation, particularly with applications for sustainability Covers a variety of disciplines, from environmental science to life science Includes a graphical abstract as well as a section on significant achievements in the field and future perspectives
