Using High-Resolution, Regional-Scale Data to Characterize Floating Aquatic Nuisance Vegetation in Coastal Louisiana Navigation Channels.

摘要

Aquatic vegetation control. Traditionally, the US Army Corps of Engineers (USACE) New Orleans District (MVN) has relied on a team of three highly trained field personnel to monitor and determine the appropriate location and treatment frequency for floating nuisance aquatic vegetation (AV) within their area of responsibility (AOR) in coastal Louisiana (Figure 1). Recently, the MVN has experienced a reduction in funding under the Removal of Aquatic Growth (RAG) Program. As a result of decreased funding, infestations have not been routinely monitored and normal control operations have not been performed. While concern about infestations is increasing, assessment and management remain insufficient, resulting in a high potential for impeded navigation on waterways in the district. In the absence of an active RAG program, the USACE Engineer Research and Development Center (in coordination with MVN) investigated the effectiveness of remote sensing to evaluate and track the growth of nuisance aquatic vegetation.
