Abstract:
In 2009, the state of Hawaii established the Kahekili Herbivore Fisheries Management Area (KHFMA) in West Maui. Fishing for herbivores (parrotfishes, surgeonfishes, chub, sea urchins) is prohibited within the KHFMA, as the goal is to use this form of marine management to prevent and possibly reverse shifts from coral to macroalgal domination, possibly evident on reefs at the KHFMA in recent years. The NOAA Coral Reef Conservation Program (CRCP) has provided support for NOAA Coral Reef Ecosystem Division (NOAA CRED) staff to assist Hawaii Division of Aquatic Resources (HDAR) staff with maintaining long-term biological monitoring of the KHFMA, using methods implemented in pre-closure baseline surveys in 2008 by HDAR and their partners at that time. For each survey round, approximately 80-100 survey transects are conducted within the KHFMA. Survey transects are haphazardly located, with the aim of spreading locations broadly across hardbottom areas within the KHFMA. Survey teams comprising of divers and working off a small boat were haphazardly dropped over hardbottom areas throughout the KHFMA. The divers would then swim straight down to the nearest suitable habitat (hardbottom large enough to lay a survey transect in); one of the survey divers would then tie off the starting point of the survey transect and the other recorded the transect start location using a GPS in a waterproof bag attached to a float. As much as possible, surveys were always run parallel to the shoreline running approximately northwards. Survey transects were of 25m length. One of the divers conducted fish surveys, recording the species, number and size (in 5 cm slots) of all fishes recorded within the transect ahead of the diver as they swam slowly along the transect line. Fishes larger than 15 cm total length (TL) were recorded within a 4-m wide belt centered on the diver as they laid out the 25 m transect tape. At the end of the transect, the diver would then turn around and resurvey the transect line, recording species, number and size of all fishes smaller than 15 cm TL in a 2-m wide belt centered on the transect line. The other survey diver followed the fish survey diver, and conducted a photo quadrat survey of the benthos under the transect line, and then recorded all sea urchins with a 1-m wide belt, during a return swim down the transect line. Photos were subsequently analyzed using point count image analysis software, with cover recorded to lowest possible taxonomic level (species for coral, genera for macroalgae, functional group for others (crustose coralline algae, turf, sand, other sessile invert). Surveys covered by this metadata record were gathered for the project "Scientific support for Kahekili Herbivore Fisheries Management Area, Maui" conducted by NOAA CRED, and funded by the CRCP in Fiscal Years 2010, 2011 and 2012 (FY10 Project#: 20482, FY11#:F200; FY12# F374). Surveys were completed in three 'rounds', each round being an intensive 4 day survey effort. Those rounds took place on 09/01/2009-09/04/2009, 09/13/2010-09/16/2010, 02/28/2011-03/03/2011, 9/26/2011-9/29/2011, 4/23/2012-4/26/2012, 9/24/2012-9/28/2012, 4/22/14-4/25/14 and 9/19/14-9/19/14.
Purpose:
Part of an ongoing monitoring program assessing changes in fish and benthic assemblages following creation of the Kahekili Herbivore Fisheries Management Area in Maui.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Fish observations at each site were made by divers who have been trained, and met minimum standards in identifying species present at the survey locations and in estimating size of fishes in survey counts. However, all species identifications are made visually, sometimes in situations where a fish is only briefly seen. Observations, including species identification and sizing, were periodically checked during the expedition for consistency between divers, and little discrepancy was noted between divers. Data is checked after each survey trip, but there remains some possibility of typographical or other errors. Benthic cover estimates derived from analysis of photographs are dependent on image quality - although that was generally good, as photographs were taken at less than 1 m from the reef substrate and in generally clear water, using a high resolution (8 MB) digital camera. Image quality is nearly always more than sufficient for there to be high confidence in accuracy of identification of benthic genera and functional groups
Logical_Consistency_Report:
The same methods of data collection were used at each of the sites surveyed at this location, and were conducted by the same scientists.
Completeness_Report:
The survey sites were selected using a haphazard process based on available habitat and bathymetric habitats.

Process_Description:
Belt transect fish surveys are investigations that provide a high degree of taxonomic resolution for reef fish communities. The surveys were conducted by teams of two divers with locations haphazardly spread throughout the survey area. Transect placement was guided by: (1) a focus on hardbottom communities; (2) deploying lines along an isobath and parallel to shore.
