VII. Summary and Recommendations for Generalized Standard Operating Guidelines


A. General Conservation Measures Applicable to All Actions


Although each introduction of a dreissenid will require site-specific responses, actions, and strategies to address the introduction, implementing core conservation measures will help to protect and restore fish and wildlife habitat, provide long-term benefits to ESA-listed species, and minimize any short-term detrimental effects caused by control actions. When implementing control actions for dreissenids in the CRB, the following minimum conservation measures apply:

  • Incorporate climate change projections into outcome analyses to minimize effects to non-target species.
  • Obtain all relevant state and federal permits (these will vary depending on the location of the control action) and require working directly with state and federal agencies to ensure compliance.
  • Follow state and federal guidelines for timing of in-water work, incorporating any variances, if necessary.
  • Identify the type, quantity, and extent of any potential action that involves excavating more than 20 cubic yards of soil.
  • Clearly flag sensitive resource areas, equipment entry and exit points, staging, storage, and stockpile areas, and areas were no pesticides will be applied, including buffers.
  • Use existing roads and paths. If temporary roads and paths must be used:
    • minimize the number and length of these routes through riparian areas and floodplains;
    • avoid steep slopes, and if slopes are greater than 30%, ensure a civil engineer is involved in road design;
    • minimize removal of riparian vegetation;
    • Obliterate all temporary roads and paths upon project completion.
  • Use existing stream crossings, and follow any guidelines for temporary stream crossings.
  • Ensure staging, storage, and stockpile areas are 150 feet or more from water bodies or wetlands.
  • Ensure equipment is well maintained and staged more than 150 feet from a water body or wetland.
  • Implement erosion control measures, such as installing sediment barriers if the potential exists for sediment to enter the stream.
  • Implement dust abatement measures, if necessary.
  • Implement spill prevention, control, and countermeasures to avoid habitat degradation and harm to aquatic organisms and ESA-listed species.
  • Implement invasive species control measures by cleaning and inspecting equipment before entering the control area, and by cleaning and inspecting personal gear.
  • Implement NFMS-directed construction conservation measures, if necessary.
  • Implement post-construction conservation measures, such as site restoration, revegetation, site access, and obliteration.
