The effects of storm-drains with periodic flows on intertidal algal assemblages in 'Ewa Beach (O'ahu), Hawai'i.
Mar Pollut Bull. 2013 May 15; 70(1-2):162-70.MP

Abstract

Storm-water drainage systems have potential to collect and focus nutrient enriched runoff into coastal systems. Storm-drain effluent could support macroalgal production and result in altered communities. To test this hypothesis, we assessed species composition and percent cover of native and non-native benthic macroalgae at eight intertidal sites along 'Ewa Beach, Hawai'i. Three sites contain storm-drainage outlets (drain 16-52 acres) that deliver effluent into the intertidal zone whereas five sites were located ≥ 100 m away and served as comparisons to determine differences related to the presence of storm-water. Results revealed lush and diverse macroalgal assemblages, similar at all sites. Furthermore, the abundance of non-native species (Acanthophora spicifera, Hypnea musciformis) was not related to presence of storm-drains. The finding that macroalgal assemblages are not related to storm-waters is contrary to an earlier investigation in the same location and underscores the importance of sampling design and habitat variation when assessing impacts.
