The National Park Service (NPS), Bureau of Land Management (BLM), and The Nature Conservancy (TNC) are conducting coordinated conservation actions along the Colorado River corridor in Utah to enhance resource conditions and related societal values associated with this iconic riverine ecosystem. Since the late 19 th century, riverine ecosystems throughout much of western North America have been altered through the introduction of nonnative plant and fish species, water withdrawals, flow regulation by dams, and many other human activities. Riparian vegetation in the project area currently is undergoing rapid change as extensive stands of nonnative tamarisk ( Tamarix spp., the dominant woody plant in the river corridor)...
Invasive annual plants such as red brome (Bromus rubens), cheatgrass (B. tectorum), and African mustard (Malcomia africana) can have profound impacts on dryland ecosystems. Potential impacts include the alteration of fuel loads and fire regimes, as well as the competitive displacement of native plant populations. Both of these impacts can significantly degrade habitat quality for wildlife and can have important socioeconomic consequences for human society. To design science-based strategies for mitigating these impacts, managers need information on the relative abundance of invasive plant populations over time and across complex landscapes characterized by multiple management jurisdictions, a range of urban and...
