Title: Benthic Surveys in Faga'alu, American Samoa: comprehensive assessment of coral demography (adult and juvenile corals) from belt transect surveys in 2013, 2015, and 2020
Short Name: Faga'alu: BLT 2013, 2015, and 2020
Status: In Work
Publication Date: 2017
Abstract:

The data described here result from benthic coral demographic surveys within belt transects of specified length and width for two life stages (juveniles and adults) in Faga’alu, American Samoa in 2013, 2015, and 2020. The data provide information on adult coral colony counts, morphology, size, partial mortality (old and recent dead), presence and causation of disease and other compromised health conditions, including bleaching. Juvenile colony surveys include morphology and size. Taxonomic identification of adult colonies is to the species level and genus level for juveniles.

In 2013 and 2015, the survey implemented a two-stage stratified random sampling (StRS) design to assess the Faga’alu coral reef community, and a one-stage StRS design in 2020. The survey domain encompassed the majority of the mapped area of reef and hard bottom habitats in the 0–30 m depth range. The stratification scheme included cardinal position (i.e., north and south), reef zone (i.e., backreef and forereef) and depth (i.e., shallow: >0–6 m and mid-depth: >6–18 m). Sampling effort allocation was determined based on strata area and sites randomly located within strata. The StRS design effectively reduces estimate variance through stratification using environmental covariates and by sampling more sites rather than more transects per site. Therefore, site-to-site comparisons should proceed with caution.

Purpose:

These data are part of a NOAA Coral Reef Conservation Program (CRCP) funded project aimed at establishing baseline, status, and trends data for coral demographics and benthic cover and composition via Rapid Ecological Assessment (REA) surveys conducted by the NOAA Coral Reef Ecosystem Program (CREP) at Faga'alu Bay, Tutuila, American Samoa between 2012 and 2020.

In August 2012 Faga’alu watershed in American Samoa was adopted by the U.S. Coral Reef Task Force Watershed Partnership Initiative as a priority site, with the objective to reduce inputs of land-based sources of pollution to nearby coastal areas and coral reefs within the watershed. The Samoa Maritime rock quarry was found to be a major contributor to the periodic flux of excessive sediments onto the adjacent reef in Faga‘alu. In September–December 2014, mitigation actions were implemented at the Samoa Maritime Quarry, including the installation of drainage systems, alternative ground cover, and retention ponds.

Data were collected to assess the effectiveness of management actions to reduce land-based sources of pollution impacts undertaken at the Samoa Maritime rock quarry. Pre-intervention baseline data were collected in 2013 and subsequent post-intervention monitoring in 2015 and 2020. Funding provided by the NOAA Coral Reef Conservation Program (CRCP) through two internal projects entitled. 1) Comprehensive Baseline Assessment and Pilot Test of Outcome Performance Measures in Faga’alu Bay, American Samoa, awarded to Suzie Holst. 2) Status and Trends Assessment for Land-based Sources of Pollution Impacts on Benthic Reef Communities in Faga’alu Bay and Vatia Bay, American Samoa, awarded to the NOAA Ecosystem Sciences Division (ESD).

Supplemental Information:

An Erosion and Sediment Control Plan was implemented at Samoa Maritime quarry to reduce excess sedimentation from quarry operations, and mitigation actions from the Plan took place in 2014 to install retention basins designed to stem the input of excess sediments into Faga’alu Stream below the quarry. REA surveys conducted by CREP in 2012 and 2013 serve as the pre-mitigation baseline, and surveys conducted in 2015 by CREP and later by the American Samoa Department of Marine and Wildlife Resources serve to document the downstream effects (e.g., changes to the coral community) in Faga’alu Bay from the mitigation efforts to reduce the sediment loads upstream.

Concurrent pre- and post-mitigation monitoring of turbidity and sediment load in Faga'alu is managed by San Diego State University via the CRCP-funded project titled, "Capacity Building for On-Island Impact Assessment of Sediment Load Reduction in Faga’alu Watershed, American Samoa". Long-term monitoring of the stream is transitioning to the American Samoa Environmental Protection Agency.

A report entitled "Baseline surveys for coral community structure and demographics in Vatia Bay and Faga'alu Bay, American Samoa" was prepared by NOAA Coral Reef Ecosystem Program for the American Samoa Department of Marine and Wildlife Resources.

Data Quality

Accuracy:

Observations were made by experienced benthic survey personnel who have been trained, undergone a series of calibration surveys and coral taxon identification testing, and have met a set of minimum standards for colony assessment and taxon identification in each region. The accuracy of species and genus level identification was high. The lowest taxonomic level of coral identification was genus except for a select number of species that were consistently identified to species by all divers conducting the surveys.

Handheld GPS units were used to locate sites and mark site locations.

Analytical Accuracy:

The taxon code AAAA is included where the segment was surveyed and no individual colonies were found in both the juvenile and adult colony records. These are true zeros. The value -9 is a placeholder or missing value for the fields: colony length, colony width (juveniles), extent, and severity. The value -1 is included where a coral colony is a fragment.

Bias:

While colony lengths are derived from physical measurements, recent and old mortality are visual estimates; surveyors calibrate to reduce inter-observer bias

Comparability:

Survey transects were appropriately marked to allow direct, site-level temporal comparisons.

Completeness Measure:

Complete. All planned demographic data were collected.

Completeness Report:

Only forereef, hard bottom habitats were surveyed.

Conceptual Consistency:

Within each year, survey methods were consistent across all sites.

Quality Control Procedures Employed:

The quality control occurred at two major stages - 1) data entry and 2) data management. Data entry quality control included both review and manual error correction steps. Data management quality control included several standard error queries followed by correction prior to ingestion into Oracle database.

Process Step 1

CC ID: 204996
Description:

Biological surveys implemented a modified stratified random sampling design to assess the survey domain which encompassed the hard-bottom reef habitat from 0 to 18 m in depth within Faga‘alu Bay. Based on the geomorphology of the reef, the stratification scheme combined two reef zone categories (backreef and forereef) and cardinal positions (north and south) into four distinct strata: i.e., backreef north, backreef south, forereef north, and forereef south. A digital map of the survey domain was overlaid with a 30 m × 30 m (900 m2 in area) GIS layer, and grid cells containing hard-bottom reef habitat were designated as the sampling units, hereafter referred to as survey sites. Sampling effort allocation was relative to strata area and sites randomly assigned within each stratum.

Belt-transects were the focal point of the biological surveys. Coral community composition was assessed within a number of 1.0 m × 2.5 m segments located at the 0–2.5 m, 5.0–7.5 m, 10–12.5 m, 15–17.5 m, and 20–22.5 m mark along each transect; bottom-time permitting, covering a total area ranging 5–12.5 m2 per transect. Over time, protocols were adjusted to increase efficiency such that two, 25-m transects were implemented in 2012/2013, two 18-m transects in 2015, and one 18-m transect in 2020. Within segments, all adult coral colonies (≥5 cm maximum diameter) whose center fell within 0.5 m on either side of the transect line were identified to the genus-level and measured for size (maximum diameter to nearest cm). Juvenile coral colonies (<5 cm), distinguished by the presence of a distinct tissue and skeletal boundary (not a fragment of a larger colony), were surveyed within three 1.0 m × 1.0 m segments at the 0–1.0 m, 5.0–6.0 m, and 10.0–11.0 m mark of each transect (covering 3 m2 per transect). Juvenile colonies were identified to genus and measured for size (maximum diameter to nearest 5 mm).

In addition, still photographs were collected were taken every 1 m to record the benthic community composition at predetermined points along the same transect(s) lines with a high-resolution digital camera mounted on a pole. This work generates 30 photographs per site, which are later analyzed by CREP staff and partners using the computer program CoralNet. This analysis is the basis for estimating benthic cover and composition at each site. These data are documented separately.

Survey protocols followed the National Coral Reef Monitoring Program methodologies historically implemented by NOAA's Ecosystem Sciences Division.
