Mapping Elaeagnus Umbellata on Coal Surface Mines using Multitemporal Landsat Imagery
… management practices. The invasive autumn olive (Elaeagnus umbellata) is abundant on former coal surface mines, often outcompeting native trees due to its faster growth rate. The frequent revisit time and spatial and spectral resolution of Landsat satellites make Landsat imagery well suited for …

Physiological and nutritional changes in nitrogen fixing trees associated with autumnal senescence and chilling
… temperate woody deciduous plants, autumn olive (Elaeagnus umbellata Thunb.), black locust (Robinia pseudoacadia L.), American sycamore (Platanus occidentalis L.) and honey locust (Gleditsia triacanthos L.), was studied during the autumns of 1987 and 1988 on two physically and nutritionally …

Understanding Invasive Species Impacts on Reclaimed Surface-Mined Lands
… invaded by non-native plants. Autumn olive (Elaeagnus umbellata) is one of the most prevalent invasive species on reclaimed mines in Appalachia and viewed as one of the main hindrances to the successful reclamation of mined land to restore native forests. In order to better assess the impact …

Tocopherol (vitamin E) content in invasive browse species on underutilized Appalachian farmland
… rose (Rosa multiflora Thunb.), autumn olive (Elaeagnus umbellata Thunb.), and Morrow's honeysuckle (Lonicera morowii Gray) in replicated plots at a site in southern West Virginia during the 1999 growing season. Alpha-, beta-, gamma-, and delta-tocopherol were extracted with hexane, separated …

Effects of non-native woody plant species on shrubland birds of conservation concern
… non-native shrub in Illinois (autumn olive (Elaeagnus umbellata), honeysuckle (Lonicera spp.) and multiflora rose (Rosa multiflora)), influenced birds’ physiological health and condition. I found that non-native plant species, specifically multiflora rose, negatively associated with shrubland …

Influence of fire and habitat on the removal of invasive plant seeds by granivores in longleaf pine savannas
… removal for four species of woody exotic plants (Elaeagnus umbellata, Albizia julibrissin, Triadica sebifera, and Melia azedarach), in longleaf pine savanna that varied spatially in time since fire, in the Sandhills of North Carolina. I selected eight sites burnt one growing season prior, and nine …

Reclaiming the Appalachian Landscape: Understanding Surface Mine Reclamation Through Remote Sensing
… focus on the invasive shrub Autumn olive (Elaeagnus umbellata). The classification achieved area-weighted overall accuracies between 74.3% and 76.8%, revealing that Autumn olive occupies approximately 9.8% of mined land in Virginia, peaking in prevalence on sites 14 years post-disturbance. …

Assessing the potential of mixed grazing goats with beef cattle to improve animal performance and increase the utilization of marginal pasturelands in the Appalachian coal region
… (Rosa multiflora Thunb. Ex Murr.), autumn olive (Elaeagnus umbellata Thunb.), and sericea lespedeza (Lespedeza cuneata (Dum.-Cours.) G. Don). The steep topography and low economic returns from beef cattle make conventional control methods inhibitive. Goats are effective browsing on invasive plant …
