- Abstract:
-
Line point intercept (LPI) surveys and benthic composition
assessments were conducted during Rapid Ecological Assessments
(REA) as part of the Pacific Reef Assessment and Monitoring
Program (RAMP) cruise HA1008 in Main Hawaiian Islands from
20101007 to 20101105. Surveys are conducted by the Coral Reef
Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries
Science Center (PIFSC) at biennial intervals to support a
long-term NOAA Coral Reef Conservation Program (CRCP) for
sustainable management and conservation of coral reef
ecosystems. During the cruise, 15 REA sites were surveyed at
Maui in Main Hawaiian Islands. Benthic biologists from NOAA's
Coral Reef Ecosystem Division conducted Line Point Intercept
surveys to quantitatively document the benthic cover at
pre-determined long-term monitoring REA sites. Two linear 25 m
transects were surveyed with a 5 m inter-transect region between
the end of Transect 1 and the start of Transect 2. The LPI diver
determines the benthic composition at 20 cm intervals for a
total of 125 data points per transect. All living benthic
elements (e.g., coral, algae, and other invertebrates) were
identified to the lowest taxonomic level possible, often
substituting functional group categories for turf algae and
crustose coralline algae when identification in the field was
extremely difficult. In cases where the substrate is bare or
covered with turf algae, the substrate composition is also noted
as either sand, rock, rubble, carbonate pavement, or dead coral.
The data allows for the assessment and monitoring of species
composition and abundance and provide the basis for computing
quantitative estimates of percent cover at higher taxonomic
levels like functional group (live coral, macroalgae, turf
algae) or on a finer taxonomic resolution such as genus level.
- Purpose:
-
Part of a long-term monitoring program at biennial intervals
which documents the state of the reefs.

REA surveys are investigations that provide a high degree of
taxonomic resolution for coral, algae, and other
macroinvertebrate communities. The majority of REA surveys
were conducted along the forereef slopes of individual islands
at depths between 10 and 20 m. However, additional habitats
including lagoonal-type patch reef and offshore oceanic banks
were surveyed when they existed. During REA surveys,
biological assessment teams follow highly structured protocols
that are repeated at each REA site. Upon arrival at an REA
site, divers entered the water and deployed two 25 m transect
lines which are shared with coral surveys that gather
community structure, diversity, recruitment, and health status
data. The sampling effort takes between 60 and 80 min to
complete. The selection of REA sites was made in close
consultation with local agencies. Factors considered during
REA site selection included: (1) ensuring a range of sample
sites representative of the benthic and reef fish habitats
around each island; (2) selecting a mixture of sites within
and outside of marine protected areas; (3) selecting a mixture
of both 'impacted' and 'least impacted' sites; (4) selecting
some sites adjacent to local villages; and (5) selecting a
number of sites that could be compared to and complement
previous assessment and monitoring work as well as future
coral reef monitoring proposed by local agencies. It is
important to note that access to REA sites can be limited by
wave exposure, weather conditions, and other environmental
factors such as currents, which can affect the ability to
re-survey sites between years. Transect placement was guided
by: (1) a focus on hard-bottom communities; (2) deploying
lines along an isobath to the extent possible at each site,
and (3) laying the transect lines into the prevailing current.
