Wetland restoration is commonly practiced as part of conservation programs or wetland mitigation, which attempts to offset human-created losses of natural wetlands. However, because of the intrinsic and human-derived value of wetlands, it is critical to determine whether these wetlands truly act similarly to natural wetlands. One role of wetlands is to provide habitat for a diverse array of wildlife species. Small mammals are often overlooked taxa in wetland restoration efforts. However, they are essential to the wetland system because they influence vegetation and are prey for higher trophic level wildlife. I discuss considerations of restored wetlands, wildlife responses to these wetlands, and the role of small mammals in wetlands in Chapter 1.In Chapter 2, I devise a study to determine whether small mammal communities are similar in restored and natural wetlands. I assess apparent abundance, occupancy, relative density, mass, diversity, richness, evenness, and community composition of small mammal communities from 14 restored wetlands and 12 natural wetlands in West Virginia, USA, sampled from June-August of 2020 and 2021. Over 10,060 trap nights, I captured deer mice (Peromyscus maniculatus), white-footed mice (Peromyscus leucopus), meadow voles (Microtus pennsylvanicus), northern short-tailed shrews (Blarina brevicauda), meadow jumping mice (Zapus hudsonius), and eastern chipmunks (Tamias striatus) at both wetland types, and woodland jumping mice (Napaeozapus insignis), masked shrews (Sorex cinereus), and one southern flying squirrel (Glaucomys volans) at exclusively natural wetlands. I found all aspects to be similar between wetland types, apart from apparent abundance of deer mice, which was higher in natural wetlands (P<0.01), and total small mammal apparent abundance was again higher in natural wetlands (P<0.01). My results suggest that restored wetlands are similar to natural wetlands for small mammal communities in most aspects.In chapter 3, I determine the features of restored wetlands that most affect small mammal communities. Specifically, I examined the effects of age and environmental variables in 14 restored wetlands spanning the three ecoregions in West Virginia. I determined the apparent abundance of deer mice (P = 0.01), white-footed mice (Peromyscus leucopus) (P<0.01), and meadow voles (P<0.01) decreased with wetland age. Furthermore, occupancy probabilities of meadow voles decreased with wetland age (P = 0.03). Diversity and richness increased with wetland age (P<0.01), but apparent species richness was not affected by wetland age (P = 0.895). Of 18 environmental variables, including wetland age, model selection showed apparent abundance of white-footed mice, meadow jumping mice, and total small mammals to be most influenced by wetland size, meadow vole apparent abundance to decline with average tree and shrub canopy cover, and deer mice apparent abundance to decrease with vegetation community similarity. Although both white-footed mice and meadow jumping were affected by wetland size, apparent abundance of white-footed mice decreased with wetland size. In contrast, apparent abundance of meadow jumping mice increased with wetland size. There was model selection uncertainty for the apparent abundance of northern short-tailed shrews and eastern chipmunk, occupancy probability of individual species, diversity, richness, or evenness in created and restored wetlands. Therefore, when designing wetlands, managers should consider how age impacts different aspects of the community at various stages of wetland restoration and should manage accordingly. Moreover, wetland managers should consider the impact of wetland size on different species to better host small mammal communities.
