Resource Description: NODC Accession Number 0002277
The first part of the survey was done with volunteers counting the people using the Ke'e beach area, and what the visitors did while they were there. The studies for this survey were done in June and July of 1999, and surveys are continuing by the Hui Maka'ainana O Makana (the local organization in the area committed to community based management).
The surveying was done from June 1 to August 15, 1999. The human use survey data report is from the dates of July 3, 7 and 11, 1999. Only zones #1 and #2 were used because of the number of volunteers available. Zone 1 was the impact area at Ke'e lagoon and Zone 2 was approximately 200 meters down the beach. Volunteers were selected from the community and Hui, and did the actual counting and entry onto the survey forms. This data set is not large enough to establish anything more than baseline information and more data needs to be collected. The Hui Maka'ainana O Makana is currently collecting more data using the same data sheet. This data will be available upon request.
Zone 2 will not be monitored in the future, because the usage is so small with very little data generated. The exception to this is on windy days with high tide in the summer months when windsurfers use the area. On the day noted (Sunday, July 11) the highest number of windsurfers in the water at one time was 16, and the maximum people on the beach at Ka'ilio Point was 27. This is a seasonal situation, and only happens in the summer, at high tide heights and windy days.
The reef impact work was done by diving the reef with SCUBA and snorkel gear numerous times, and doing transects on the reef flat. The dives were to gather information about the area and make observations, while the transects were to distinguish human impact of walking on the reef flat itself. The transects were done in two areas, an impact area and a control area. A total of ten 10 m transects were set out in both of the areas. Five of these transects were randomly selected in each area and then five points were randomly selected on each transect line. So, five transect lines were selected in each area, and a total of twenty-five 1 sq. m quadrats were used to compute percent coverage of coral, algae, and other substrate. See kee_figure3.jpg for an outline of the coverage. The quadrat surveying was done at low tide, while the reef was exposed.
The impact area was so designated because it was close to the swimming lagoon and area of the major concentration of people. This concentration of people is close to the parking lot and in front of the small swimming lagoon, this area is noted as Point A in Figure 3. The major flow of people across the reef is from this area to a small indentation in the reef at Point B, and also noted in Figure 3. When people are walking on the reef, the main concentration seems to be in a corridor from Point A to Point B. This is the major impact area as noted in Figure 3 to the left of the line on the graphic. This information has been gathered by observation, and was used to divide the study site. This impact area was studied by percent cover and compared to the control area to the right of the line in Figure 3. Thus these two areas of reef flat were studied, next the results were compared.
The categories looked for in the percent cover on theses transect line were turf algae (Turf), corralling encrusting algae (Crust), macro algae (Macro), coral (Coral), sand (Sand) and rubble, and bare substrate or basalt rock (Bare Substrate). The amount of Bare Substrate was negligible.
