* » Abstract |
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, Honokohua, 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, dranages (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 is 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), 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. |
* Purpose |
These data are part of a NOAA Coral Reef Conservation Program (CRCP) funded project to support implementation of the Wahikuli-Honokowai Watershed Management Plan for West Maui, Hawaii. Through this project, long-term coral reef monitoring was established at three stream mouths to assess the efficacy of watershed management activities intended to reduce land-based sources of pollution at the West Maui U.S. Coral Reef Task Force (USCRTF) watershed priority site (Wahikuli-Honokowai). This work complements project specific watershed monitoring, as well as long-term coral reef monitoring conducted in the Kahekili Herbivore Fishery Management Area by the Hawaii Division of Aquatic Resources (DAR) and the NOAA Coral Reef Ecosystem Program (CREP) taking place along the coast between the stream mouths. The project methodology was developed in partnership with the Hawaii DAR, West Maui Watershed Coordinator, U.S. Geological Survey, University of Hawaii, and the USCRTF watershed initiative. |

Coral Reef Ecosystem Program (CREP) Data Sharing Recommendations, version 9.0 updated August 12, 2015: CREP welcomes the opportunity to collaborate on research issues contributing to the scientific basis for better management of marine ecosystems. CREP has a very diverse set of field activities that generates large volumes of data using an array of data collection protocols. The following recommendations are for your consideration as you use this data: 1) Data analyses should take all field exigencies into account. The most effective way to do this would be active collaboration with CREP principal investigators. 2) In all presentations, product releases, or publications using data generated by CREP, proper acknowledgement of both CREP and the individuals responsible for data collection is expected. Citing the DOI (if available) is preferred, a non-DOI example is listed below. 3) If you collect or generate data for the same study areas, CREP requests that you share relevant information on complimentary data collections. 4) Those receiving data are strongly urged to inform the CREP Data Management Team of any errors and discrepancies that are discovered during the course of using these data. They are further urged to bring to the attention of the Team all problems and difficulties encountered in using these data. This information is necessary in order to improve the collections and to facilitate more efficient and economical data processing and retrieval. The users are asked to supply copies of any missing data that may be located, and to provide information as to significant subsets and special aggregations of data that are developed in using the material provided. Example citation: "This publication makes use of data products provided by the Coral Reef Ecosystem Program (CREP), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA), with funding support from the NOAA Coral Reef Conservation Program (CRCP).

» Description |
Adjacent to each of the main watershed drainages (i.e., Wahikuli, Honokowai, and Mahinahina in the south; and Kahana, Honokeana, Honokohua, and Honolua to the north), two permanent, long-term benthic monitoring stations were established (except for Honokohua; only one station established); shallow (0-6 meter) and/or mid-depth (6-15 meter). Within each monitoring station two-to-three replicate survey sites were established; replicate survey sites were several meters apart, given that West Maui coral reef track exhibits a fingerlike-reticulate geomorphology. And, within each replicate site, surveys were conducted along one, 25-meter line transect (same transect as for demographic surveys, just longer). Using a Line-Point-Intercept protocol, hard corals, octocorals, macroalgae, crustose coralline red algae, and target macroinvertebrates were identified to the finest level of taxonomic resolution and recorded at 25-centimeter intervals, starting at the 0.25 meter mark to the 25.0 meter mark. These surveys generate 100 points per survey site/transect (300 points per monitoring station/depth) that can be used to generate estimates of percentage of cover of benthic organisms. |

» Description |
Additionally, in concert with Line-Point-Intercept surveys, photoquadrat images were collected to record the benthos at predetermined points along the same 25-meter transect line with a high-resolution digital camera mounted on a photoquadrat pole, starting at the 1 meter mark to the 25 meter mark. This work generates 25 photographs per site that provide a durable pictorial record of the benthos. These photographs can be analyzed, if needed, by staff at NOAA Coral Reef Ecosystem Program (CREP) using computer image analysis software to generate benthic data (for additional details regarding CREP's current standard operating procedure to analyze benthic images, see https://www.st.nmfs.noaa.gov/confluence/display/CRED/Standard+Operating+Procedures [*must have a NOAA account to view this document]). |
