Engineering Specification Guidelines For Wetland Plant Establishment And Subgrade Preparation

Engineering Specification Guidelines for Wetland Plant Establishment and Subgrade Preparation

This report explains the process involved when proceeding from a wetland mitigation design concept to a fill' engineering package that is suitable for public bid and advertisement The information provided is geared toward educating nonengineering professionals engaged in developing wetland mitigation specifications The biological foundations for the various elements are first presented, followed by full guideline specifications. The vegetation specifications address site preparation, plant material acquisition, transport, handling, and storage of seeds, herbs, and saplings, planting methods for various stock types, different seeding methods, tiring of planting in conjunction with seasonal variations, hydrological considerations such as tidal cycle, water level and rainfall patterns, equipment access and type, protection measures for herbivory, inundation and vandalism, fertilization and amendrnent application, soil-nutrient testing, substrate handling, trppsport, and storage and minimization of impacts on existing wetland resources. The subgrade specifications target construction methods and equipment, soil-material testing, and performance. The other soil-related specifications quarantine and safeguard existing resources such as friable surface soils and wetland topsoils that can be used to "seed" a site.

Wetland Landscape Characterization

Wetlands are, by their very nature, ephemeral and transitional, which makes them challenging to characterize. Yet the need for characterizing wetlands continues to grow, particularly as we develop a better understanding of the wealth of ecosystem services that they provide. Wetland Landscape Characterization: Practical Tools, Methods, and Approaches for Landscape Ecology, Second Edition shows how wetland characterization tools, methods, and approaches can be integrated to more effectively address twenty-first-century wetland issues. A Practical Toolbox for Integrated Wetland Landscape Characterization The book explains how to locate, identify, and map the extent of wetlands to learn more about their importance to society and the larger landscape. It examines jurisdictional, regulatory, and practical applications from the scientific, engineering, and lay perspectives. Fully updated, the second edition reflects an emerging infrastructural, ecosystem goods-and-services perspective to better assist readers who may encounter these concepts and challenges as they assess and characterize wetlands. Examples and case studies illustrate a variety of situations and solutions, highlighting the use of current techniques to assess, inventory, and monitor natural resources under changing conditions. These examples offer lessons and ideas for the issues encountered every day by wetland landscape ecology practitioners. The book also refers readers to additional resources to help them solve specific challenges. New in This Edition Updates of practical geospatial methods More project-driven examples A description of the pitfalls of using ecological data at landscape scales, along with solutions Alternative techniques for a variety of practitioners Linkages between field and landscape ecological practices Online resources for practitioners New illustrations This book helps readers develop the concepts, skills, and understanding of how to best achieve project goals in the rapidly changing disciplines of landscape science and wetland ecology and management. A valuable resource, it provides practical tools, methods, and approaches for conceptualizing, designing, and implementing broad-scale wetland projects that take into account critical societal linkages.
