    • Determining Watershed Management Efficacy in West Maui: line-point-intercept and photo quadrat surveys of benthic communities for benthic cover from 2014-06-24 to 2015-07-31 (NCEI Accession 0138585)

    Metadata Updated: November 1, 2023

    The focus of the Wahikuli-Honokowai Watershed Management Plan is the land use practices and alterations affected in the agricultural and urban districts that have upset the natural drainage patterns and ecohydrologic balance and services the watersheds provide. As the approach to reducing the effects of land-based sources of pollution, the Wahikuli-Honokowai Watershed Management Plan identifies nine priority projects to reduce, capture, and remediate the impacts of non-point source pollutants through the implementation of management practices in priority areas. The Watershed Management Plan also includes recommendations for strategic, long-term trend monitoring of the health of the coral reef ecosystem, which provides information that can be correlated to the implementation of solutions to reduce land-based non-point source pollutants. Kahekili Beach Park reef and the coastal areas to the north are considered high priority. Corals in this region have been severely impacted by land-based pollutants, causing coral dieback and reducing coral cover. To fill in the gap, a baseline assessment for benthic cover data (described here) along with coral demographic metrics, has been conducted at the mouths of the Mahinahina, Honokowai, and Wahikuli, Kahana, Honokeana, Honokohau, and Honolua stream drainages in West Maui, Hawaii, to track and evaluate the efficacy of implemented management practices. The installation of permanent survey transects will provide long-term time series to quantify changes in the reef benthic community. Sediment flux, and turbidity data are also collected at the Mahinahina, Honokowai, and Wahikuli drainages (described separately). The data described here were collected via line-point-intercept (LPI) and photo quadrat surveys by the NOAA Coral Reef Ecosystem Program (CREP) according to established protocols. These data include:

    1) an assessment of benthic cover for the selected monitoring sites; and 2) benthic photographs to serve as a permanent record of the site.

    Data are available for surveys conducted in 2014 and 2015. The LPI data can be accessed online via the NOAA National Centers for Environmental Information (NCEI) Ocean Archive, accession #0138585, and the benthic photographs are available upon request from CREP. Additionally, belt transect surveys of coral demography (adult and juvenile corals) were conducted (described separately in NCEI Accession 0137092), and turbidity sensors, sediment traps, and sediment pods were deployed by project partners to provide information on sediment loads, sediment accumulation rates, and sediment composition. As watershed management projects are implemented, changes in sediment and nutrient loading and the resulting impacts on the reefs can be monitored over time.
