“…Alder and other obligate species fail to establish mature stands because of flooding scour of streambanks and also likely it is at the lower limits of its range. This community is similar to the alder type described by Szaro (1989Szaro ( , 1990.

“…Hence, small statured plants can be co-dominants as mid-story components. A major difference between this study and Szaro (1989Szaro ( , 1990) is red willow (Salix laevigata). Red willow is abundant on the UVR, whereas S. irrorata and S. bondplandiana are noted important species in Szaro (1989).…”

“…Exceptions are noted for instances where upland species, e.g., Utah juniper (Juniperus osterosperma), are co-dominant in the mid-and understory. Szaro (1989Szaro ( , 1990) emphasized tree dominance, whereas this study considered all woody species in a structural context. Hence, small statured plants can be co-dominants as mid-story components.…”

“…Previous vegetation studies on the Verde River Szaro 1989Szaro , 1990Black andothers 2005, Stromberg 2008) have provided some insight into riparian habitats, but the vegetation descriptions were unusable to managers interested in sensitive aquatic species management or their work was limited to flow-vegetation studies of the middle or lower Verde River (Beauchamp and Stromberg 2008). Shaw (2006) examined historic plant communities of the watershed and noted limited evidence of riparian communities.…”

Szaro and Patton (1986) and Szaro (1989Szaro ( , 1990 provided generalized vegetation type descriptions that included the Verde River.

This volume is a state-of-knowledge synthesis of monitoring and research conducted on the Upper Verde River (UVR) of Arizona. It contains information on the history, hydrology, soils, geomorphology, vegetation, and fish fauna of the area that can help land managers and other scientists in successfully conducting ecosystem management and future monitoring and research in this important Southwest river ecosystem. Chapter 1 provides an introduction to the UVR's location, vegetation, climate, soils, and watersheds. A historical and pictorial perspective of the UVR is presented in Chapter 2. The hydrology of the watershed and its current physical condition are covered in Chapters 3 and 4. Geomorphic relationships of the UVR channels are described in Chapter 5. The woody and herbaceous vegetation of the UVR are presented in Chapters 6 and 7. Water quality status and issues of the river are discussed in Chapter 8. The status of the fish fauna and other aquatic organisms are described in Chapter 9. Chapters 10 through 12 present summaries of information resources, research recommendations, a summary of this volume, and conclusions.

Patterns of plant species richness and community composition were studied in diverse riparian zones. Eight rivers in south‐western France, one river in north‐western USA and four rivers in south‐eastern Spain were compared. A brief review is presented of factors that have been singled out as controlling diversity along rivers. The proportions of plant group classified according to life‐span, morphology, ruderality and location along the rivers were analysed. Both proportions of plant traits and total species richness differed considerably between rivers. Semi‐arid rivers were more influenced by local patterns than the other rivers. The patterns exhibited by true riparian species and invading, essentially non‐riparian species, showed the importance of the relationships between the river and its close surroundings. The mean proportion of ruderals remained roughly the same in all rivers, suggesting some regulatory mechanisms independent of the general environmental settings. The longitudinal patterns of species richness in riparian plant communities of the oceanic rivers could be related to the intermediate disturbance hypothesis, whereas semi‐arid rivers showed very irregular patterns of species richness along their courses, as a consequence of the irregular water availability. Exotic and ruderal species were more sensitive than other groups to the longitudinal zonation of the rivers and to environmental factors influenced by humans. Also, the permanency of superficial water appeared as a major factor in the control of riparian community structure in semi‐arid regions.

PROFILE: Wetland Mitigation Banking: A Framework for Crediting and Debiting

/ Wetland mitigation banking as a resource management tool has gained popular support for its potential to provide an ecologically effective and economically efficient means to fulfill compensatory mitigation requirements for impacts to aquatic resources. Although this management tool has been actively applied within the past 10 years (C. Short, 1988, Mitigation banking, in Biological Report 88(41):1-103), assessment of credits and determination of a compensation ratio that reflects existing and/or potential functional condition in a mitigation bank has been a formidable task. This study presents a framework for a systematic approach for determination of credits and debits and subsequently the compensation ratio. A model for riparian systems is developed based on this framework that evaluates credits and debits for spatial and structural diversity, contiguity of habitats, invasive vegetation, hydrology, topographic complexity, characteristics of flood-prone areas, and biogeochemical processes. The goal of developing this crediting and debiting framework is to provide an alternative to the current methods of determining credits and debits in a mitigation bank and assigning mitigation ratios, such as best professional judgement or use of preset ratios. The purpose of this crediting and debiting framework is to develop a method that (1) can be tailored to evaluate ecological condition based on the target resources of a specific mitigation bank, (2) is flexible enough to be used for evaluation of existing or potential ecologic condition at a mitigation bank, (3) is a structured and systematic way to apply data and professional judgment to the decision-making process, (4) has an ecologically defensible basis, (5) has ease of use such that the level of expertise and time required to employ the method is not a deterrent to its application, and (6) provides a semiquantitative measure of the condition of aquatic resources that can be translated to a mitigation ratio.
