Description
Worldwide, riverine floodplains are among the most endangered landscapes. In response to anthropogenic impacts, riverine restoration projects are considerably increasing. However, there is a paucity of information on how riparian rehabilitation activities impact non-avian wildlife communities. I evaluated herpetofauna abundance, species richness, diversity (i.e., Shannon and Simpson indices), species-specific responses, and riparian microhabitat characteristics along three reaches (i.e., wildland, urban rehabilitated, and urban disturbed) of the Salt River, Arizona. The surrounding uplands of the two urbanized reaches were dominated by the built environment (i.e., Phoenix metropolitan area). I predicted that greater diversity of microhabitat and lower urbanization would promote herpetofauna abundance, richness, and diversity. In 2010, at each reach, I performed herpetofauna visual surveys five times along eight transects (n=24) spanning the riparian zone. I quantified twenty one microhabitat characteristics such as ground substrate, vegetative cover, woody debris, tree stem density, and plant species richness along each transect. Herpetofauna species richness was the greatest along the wildland reach, and the lowest along the urban disturbed reach. The wildland reach had the greatest diversity indices, and diversity indices of the two urban reaches were similar. Abundance of herpetofauna was approximately six times lower along the urban disturbed reach compared to the two other reaches, which had similar abundances. Principal Component Analysis (PCA) reduced microhabitat variables to five factors, and significant differences among reaches were detected. Vegetation structure complexity, vegetation species richness, as well as densities of Prosopis (mesquite), Salix (willow), Populus (cottonwood), and animal burrows had a positive correlation with at least one of the three herpetofauna community parameter quantified (i.e., herpetofauna abundance, species richness, and diversity indices), and had a positive correlation with at least one herpetofauna species. Overall, rehabilitation activities positively influenced herpetofauna abundance and species richness, whereas urbanization negatively influenced herpetofauna diversity indices. Based on herpetofauna/microhabitat correlations established, I developed recommendations regarding microhabitat features that should be created in order to promote herpetofauna when rehabilitating degraded riparian systems. Recommendations are to plant vegetation of different growth habit, provide woody debris, plant Populus, Salix, and Prosopis of various ages and sizes, and to promote small mammal abundance.

Description
This project focuses on providing a series of Sensory Design Guidelines (SDG) for the creation of restorative environments for people and nature promoting cognitive health, motor skill development, and outdoor therapy for urban society’s most vulnerable. Although the project framework is structured around guidelines for the creation of spaces specifically designed for children with Sensory Processing Disorder, it is not restricted to that specific application. Guidelines are further developed structured around inclusive and universal design approaches.
The project is divided into four sections. The first section explores what Sensory Processing Disorder is, how Occupational Therapy with Sensory Integration positively impacts healing processes, and how designers can expand this processing into the natural healing environment of the great outdoors in a toxic and urbanized world. The second section discusses the vision, goals and objectives for implementation of Sensory Design Guidelines as discussed in the third section. And finally, the fourth section provides a conceptual example of what SDG would look like when applied to a physical site along a natural corridor in a densely urbanized landscape.
The final example of SDG implementation is applied to a site along the Salt River (Rio Salado) Corridor in Phoenix, Arizona. The Corridor is the subject of a coordinated inter-agency public/private restoration initiative spanning more than fifty-five miles along the Salt River that has been strongly supported by former U.S. Senator John McCain and greatly influenced by active involvement from Arizona State University students. The designated example site is designed as one site to be utilized in a larger network of easily accessible Sensory sites, each to be designed with a different approach to sensory development, as well as variation in challenges based on age and sensory abilities. Guidelines are intended to work in conjunction with future local projects promoting social and ecological growth and wellbeing, such as the Phoenix site is intended to work in conjunction with future Rio Re-imagined projects.
The findings, guidelines, and examples provided throughout the paper are focused on re-inventing the relationship between the built and natural environments in the urbanized landscape into one of daily nature-engagement and can be applied to any group living within an urban setting. By designing for society’s most vulnerable populations, design application benefits not only the individual, but creates a resilient, healthy environment for the entire urban population today, and for future generations.
