Product Description
A Handbook for Stream Enhancement and Stewardship is a basic resource intended to help individuals, groups, organizations, companies, communities, and governments plan and carry out environmentally sound, cost-effective stream corridor assessment, enhancement, and stewardship programs. Using the watershed as the basic unit of reference, the Handbook provides ideas and information with which readers can assess and document local stream conditions, learn about and evaluate methods of enhancement, devise and implement enhancement plans, and then maintain the stream and stream corridor in its enhanced state of better health and balance. While not a comprehensive technical manual for professionals trained in stream restoration, this resource does provide a solid foundation by which volunteers and lay readers may become informed observers, advocates, and organizers of stream enhancement programs and effective participants in their implementation.

This is definitely a handbook, nothing else.......2006-08-24
I read this entire book only to discover it is a handbook. It would be great as a textbook. It was written by several writers which made it difficult to read. Some were better writers than others and some should have scaled down their writing.
Recommended as an expert informational resource for environmental and waterway restoration and conservation.......2006-06-12
A Handbook For Stream Enhancement And Stewardship from the Izaak Walton League of America is an excellent study of conservationist activities in dynamically aiding the restoration, enhancement, and environmental maintenance of rivers and streams. Deftly providing readers with a conceptual grasp of the "stewardship" responsibilities of various groups, organizations, individuals, companies, communities, and government planning agencies, A Handbook For Stream Enhancement And Stewardship informatively presents a ideas and expertise with which to actively make a difference in maintaining and enhancing rivers and streams for purposes of the flora and fauna dependent upon them, as well as the critically important role of the stream with respect to watershed dynamics. A core addition to personal, professional, environmental activists, academic, and community library Environmental Studies reference collections, A Handbook For Stream Enhancement And Stewardship is very strongly recommended as an expert informational resource for environmental and waterway restoration and conservation.

Description:
Here, we develop an approximate solution to the classical Lotka-Volterra two-species differential equation with application to plant system interactions. The model seeks to estimate the threshold species densities necessary for the native/crop, woody stemmed species (e.g. cottonwood; Populus deltoids and willow; Salix goodinigii, for western riparian systems) to ''out-compete'' the exotic/weed species (salt cedar; Tamarix ramosissima and Russian olive, Elaegnus angustifolia) and thereby reduce them. Explicitly our goal is to predict to what degree must one reduce the exotics/weed species and increase the native/crop to achieve a plant interaction system that leads to long-term reduction of the exotic/weed species. Preliminary results of predicted results compared with field data for a Loblolly pine (Pinus taeda)/opportunistic hardwood species interaction indicate that the analysis provides plausible results. Similar computations using a Douglas-fir/tanoak interaction show analogous behavior. Although, it is clear that a considerable level of research effort has been applied to woody stemmed, exotic/weed species ecology, we believe our approach involving close coupling between classical mathematical species competition models (Lotka-Volterra) and a field management predictive capability. As the necessity for quantitative planning tools becomes fundamental to many ecosystem restoration programs, models such as developed here may provide a useful first approximation.

Description:
Over the course of a year, we conducted a study on future restoration work in the Sanyang wetland, a degraded permanent river wetland that is close to the center of Wenzhou city, China. Our main objective was to plan the restoration by using both structural indices and a valuation of the wetland's ecosystem services, thereby linking the science to human welfare. Based on field surveys and research into the history of the study area, we calculated both the potential and current values of the main ecosystem services. The results showed that the potential value at the Sanyang wetland was 55,332yuanha^-^1yr^-^1, while the current value was only 5807yuanha^-^1yr^-^1. In other words, 89.5% of the service value needs to be restored for the wetland to reach its potential value. We recommend that the service provided by the wetland's ability to purify the environment needs to be the top priority in restoration. In addition, water and sediment quality should also be greatly improved.

Description:
A field study was conducted at Little Topashaw Creek in northern Mississippi, aimed at expanding the limited database on the survivorship of Salix nigra (black willow) cuttings planted on riparian restoration sites. We tested the hypothesis that sediment moisture availability (deficit, excess) as mediated by sediment texture and depth to the prevailing water table is a major factor governing black willow survival during the initial stage of establishment following transplanting. Replicated plots were established across elevational gradients and a range of soil texture. Each plot contained 16 planted cuttings (2.5cm diameterx2.5m length). Plot depth to water table, soil texture, and soil redox potential were measured. Plant gas exchange, leaf chlorophyll content, growth, and survival were monitored periodically over two growing seasons. Survival was best at low elevation compared to cuttings planted at mid- and high elevations. Poor survival and growth were noted for cuttings that encountered sediment moisture deficits in plots with coarse texture while the best cutting survival was recorded for intermediate sand content plots. Results indicated that plot location on the bank and soil texture are two important factors that influence riverbank restoration success. Therefore, any riparian restoration plan should include careful assessment of these factors prior to undertaking such efforts.

Description:
The restoration of phosphate mined lands in Florida is large scale, potentially covering over 300,000 acres (121,000ha), and rivals other restoration efforts like the Florida Everglades in size and complexity. The issues surrounding mining and subsequent restoration of the landscape are global, national, and local in scale. The entire system of phosphate mining and restoration involves local citizens, governmental agencies, research scientists, and industry personnel in a program that might be seen as adaptive management. It is suggested that restoration is managing adaptive self-organization of the ecosystems and landscapes and that it is the domain of ecological engineering. The past 30 years of research concerning various aspects of landscape restoration after phosphate mining are elucidated, and the research's relationship to management and regulation are discussed. Finally, the complex issues that are inherent in large restoration programs are discussed and it is suggested that a cooperative environment and vision may be the key elements that are missing.

Description:
There has been little discussion of how and when to integrate wildlife science into ecological restoration projects. The recent emergence of wetland ecosystem restoration offers an opportunity to use wildlife science to increase the probability of a project being successful. This paper traces the evolution of wetland ecosystem restoration in North America and proposes three roles for wildlife science in wetland ecosystem restoration: (1) contribute to conceptual ecosystem models, (2) develop quantitative performance measures and restoration targets that track the progress of restoration, and (3) achieve social feasibility by sustaining long-term public support for a project. The extensive knowledge base for many species of wildlife makes them especially useful for contributing to conceptual ecosystem models. Wildlife species are often the subject of long-term monitoring and research because they have commercial value, are conspicuous, or have aesthetic appeal. Wildlife parameters can be good performance measures for large-scale restoration projects because some species integrate information over large spatial scales and are long-lived. Parameters associated with threatened or endangered wildlife species should get special consideration as performance measures because the information will meet multiple needs rather than just those of the conceptual ecosystem model. Finally, wetland ecosystem restoration projects need to sustain funding over decades to ensure the restored system is self-sustaining. Wildlife are a valued resource that can help achieve the social feasibility of a project by providing a way to communicate complex science in terms that society understands and values.

Description:
Ecosystem-based management requires integration of multiple system components and uses, identifying and striving for sustainable outcomes, precaution in avoiding deleterious actions, and adaptation based on experience to achieve effective solutions. Efforts underway or in planning to restore and manage two major coastal ecosystems, the Chesapeake Bay (Chesapeake Bay Program) and coastal Louisiana (Louisiana Coastal Area Plan and Gulf Hypoxia Action Plan), are examined with respect to these four principles. These multifaceted restoration programs represent among the foremost challenges for science and coastal management in the United States and, thereby, have important implications for addressing the coastal environmental crises being experienced throughout the world. Although frameworks exist for integration of management objectives in both regions, the technical ability for the quantitatively integrated assessment of multiple stressors and strategies is still in an early stage of development. Science is also being challenged to identify sustainable futures, but emerging concepts of ecosystem resilience offer some promising approaches. Precautionary management is best conceived with regard to fisheries, but should become a more explicit consideration for managing risks and avoiding unanticipated consequences of restoration activities. Adaptive management is embraced as a central process in coastal Louisiana ecosystem restoration, but has not formally been implemented in the more mature Chesapeake Bay restoration. Based on these experiences, ecosystem-based management could be advanced by: (1) orienting more scientific activity to providing the solutions needed for ecosystem restoration; (2) building bridges crossing scientific and management barriers to more effectively integrate science and management; (3) directing more attention to understanding and predicting achievable restoration outcomes that consider possible state changes and ecosystem resilience; (4) improving the capacity of science to characterize and effectively communicate uncertainty; and (5) fully integrating modeling, observations, and research to facilitate more adaptive management.

Description:
With increasing restoration initiatives for coastal wetlands, the question of 'What are we restoring to?' becomes more pressing. The goal of this paper is to explore restoration concepts, examples, and challenges from the Pacific and Gulf coasts. One of the fundamental concepts explored is change over time - either in the controlling processes or the restoration structure - and how such changes can be meshed with the goals of various restoration efforts. We subsequently review the concepts of ecosystem trajectories, alternative restoration approaches, and the ideal attributes of functional self-sustaining restoration in the context of realities of restoration planning, design, and implementation. These realities include the dynamics of the ecosystems being restored, very real constraints that are imposed by the contemporary physical and human landscape, and the need to plan for the long term development of restoration sites recognizing that both project performance and expectations may change over time.

Book Description
Historic pioneer trails serve as some of the most fascinating links to our nation's past and retracing them can be an exhilarating and educational experience. Following the Santa Fe Trail is aimed at assisting modern travelers to enlarge their understanding of the trail and increase the enjoyment that comes from following in the wagon tracks of pioneers.
Originating in Franklin, Missouri, the Santa Fe Trail was the first and most exotic of America's great trans-Mississippi pathways to the west. Although the era of the trail ceased, its glory-days are still part of the collective imagination of America.
Complete with directions, maps, anecdotes, and historical information, Following the Santa Fe Trail takes the traveler on an authentic historic journey. Modern paved highways now parallel much of the old wagon route and with this guide a modern adventurer can retrace large sections of the trail.
Since Following the Santa Fe Trail first appeared in 1984, the trail was designated a National Historic Trail under the National Park Service and public interest has mushroomed.
This completely revised third edition now updates all directions and clarifies the changes that have taken place in the last 15 years.

Excellent travelers guide to the SF Trail today.......2006-01-11
All those planning on exploring the Santa Fe Trail should have this book with them. It is an excellent guide, filled with detailed maps, very specific driving instructions, and a great deal of background information on the sites referred to. The book begins with a brief introduction, which includes information on general histories, other guidebooks, trail ruts, various markers and the groups that placed them, and a bibliography. Then Simmons gets into the specifics of the trail, beginning at Franklin, MO, proceeding through Kansas, and covering both the Mountain Branch and the Cimarron Cut-Off separately before continuing through New Mexico to Santa Fe (with brief side trips to Taos and Albuquerque included).
Simmons is interested in all remnants and markings of the trail and pinpoints even the most forlorn DAR marker. But it's his willingness to expose just about all that can be noted by the modern traveler (even sites on private property, though he is careful about warning against trespassing) that makes this guide book so valuable. This is the Second edition, published in 1986 after a careful note-taking retracing of the trail in 1985; probably a new edition is needed to update further changes made during the last 20 years (if it hasn't been done already). Highly recommended.
With directions, maps, anecdotes, historical information.......2001-09-12
Now in a revised and updated third edition, Marc Simmons and Hal Jackson's Following The Santa Fe Trail: A Guide For Modern Travelers is written specifically to assist modern travelers who enjoy following the wagon tracks of pioneers. Following The Santa Fe Trail is packed with directions, maps, anecdotes, historical information, and everything else necessary to follow the trail of history. Now that the Santa Fe Trail has been designated a National Historic Trail under the National Park Service,it is bringing more public interest than ever to this fascinating pathway that transcends the generations. If the Santa Fe Trail perks your interest to, then Following The Santa Fe Trail is a must-read!
Santa Fe Trail Redux.......2001-09-09
Marc Simmons is the pre-eminent author on Santa Fe Trail lore and this updated version of his "Following the Trail" is better than ever! He has captured those significant, visible elements of the SFT that make it impossible to follow the Trail without this book. The pictures and maps are explicit and easy to follow. His stories and anecdotes bring the Trail to life.
If you're an SFT buff be sure to also read his book: "The Old Santa Fe Trail", a collection of essays; and his new book: "Spanish Pathways" on the history of Hispanic New Mexico.

The Almost Handy Guide to the Santa Fe Trail.......2001-05-21
Don't count on AAA or Fodor's to guide you to the wagon wheel ruts, remnants of watering wholes, or Indian ambush points along the Santa Fe Trail. On one had I was pleased to see that the noted Santa Fe Trail historian had put together a guide to the location of the remnants of the trail. Unfortunately I found details lacking, particularly when it came to local observances and current road and off-road access to the location. I was particularly disappointed by the lack of detail for the Raton, NM area of the trail.
