“…In areas where nutrients such as nitrogen and phosphorus are artificially concentrated, such as agricultural fields, sediment and nutrient pollution is released in field runoff (Lee et al 2000). Wooded and grass riparian buffers can temporarily prevent nutrient and sediment pollution from entering streams by assimilating nutrients into plant tissue, increasing soil organic matter that can store nutrients, and increasing nutrient infiltration into soil via stem and root density (Dosskey et al 2010), but riparian ecosystems are often impaired or removed altogether for drainage redirection in agricultural settings (Smiley et al 2017).…”

Live stakes are woody cuttings from wetland tree and shrub species that can root in moist soil. The use of live stakes in riparian and wetland restoration is becoming an increasingly popular technique because of relatively low costs and maintenance. However, the success of live stakes likely depends on the species, environmental conditions, and planting treatments. In particular, the benefit of artificial rooting hormone or weed control strategies have not been widely studied, particularly for eastern North American species. We performed a common garden experiment with 1800 live stakes of eight species commonly used in restoration, where stakes were randomly blocked by species and treatments, including herbicide application to control invasive plants and rooting hormone to encourage growth. We examined how the use of herbicide and rooting hormone, species, stake diameter, and planting depth of stakes affected live stake survival and growth. We found survival, growth, and response to treatments were species-dependent, and that buttonbush (Cephalanthus occidentalis), elderberry (Sambucus canadensis), and silky dogwood (Cornus obliqua) were the species with the greatest survival one year post-planting. The only species that benefited from treatments were red osier dogwood (Cornus sericea) and buttonbush, which had the best survival with rooting hormone, and silky dogwood, which had the best survival with both treatments. In addition, buttonbush showed significant clustering of surviving stakes, possibly indicating buttonbush might be most sensitive to differences in microhabitat conditions. Lastly, we provide an analysis to help conservation professionals gain insight into live stake survival, species selection, and best management practices.

Background Agriculture has greatly influenced water quality, habitats, and fish assemblages in streams of the Mississippi Alluvial Plain (MAP) ecoregion. However, MAP streams have historically been understudied compared to streams in other agricultural regions of the USA. In this study, water quality, habitat, and fish assemblage composition were assessed seasonally (spring, summer, and fall) in eight representative MAP streams located across three U.S. states. The study design included four streams containing highly agricultural watersheds (herein termed “agriculture” streams) and four streams containing mostly forested watersheds (herein termed “forest” streams), which were intended to represent reference conditions for MAP streams. Results In general, forest streams contained significantly better instream and riparian habitats than agriculture streams (P = 0.010–0.040) whereas agriculture streams contained significantly greater levels of primary nutrients (P < 0.001–0.010). Differences between agriculture and forest streams with respect to other physical and chemical variables were intermittent and season dependent. Fish assemblages in agriculture and forest streams were structured primarily along an environmental gradient reflecting instream habitat conditions, water nutrient concentrations, and benthic chlorophyll-a production. Structurally, fish assemblages in both stream types contained many regionally common species, though some species appeared to exhibit affinities for a particular stream type. Functionally, fish assemblages in agriculture streams contained more tolerant species, more omnivores, and fewer insectivores compared to forest stream assemblages, which were nearly all insectivores. Overall, one-third of the fish specimens collected in forest streams classified as intolerant species. Conclusions Our results suggested that stream water quality, habitat, and fish assemblages differed between agriculture and forest streams in the MAP, with fish assemblages exhibiting both structural and functional differences. Results were consistent with a larger body of literature from smaller, headwater streams whereby land-use changes (e.g., row-crop agriculture) impacted the physical, chemical, and biological characteristics of stream ecosystems. Results further highlight the importance of land use management and its effects on habitat diversity in stream ecosystems, and that protecting the few remaining undisturbed or less-disturbed streams should be a priority.
