Several new studies have emerged in the last two years that point to more evidence that noise negatively impacts wildlife; · There is evidence that noise detracts from a positive park visitor experience and noise generated by DBOC activities negatively affects the human wilderness experience; · Noise maps (spatial-temporal) of DBOC sound sources would be beneficial for explaining impacts on human and wildlife acoustic space; · Alternatives B and C are likely to have the same level of impacts on soundscapes; and · More supporting information is needed for assumptions about nighttime versus daytime ambient noise and propagation.
