2) Monitoring Period. Monitoring activities will commence on May 1 , 2003 and continue through approximately October 31 , 2003 , as stipulated below. 3 ) Daily Morning Surveys. Daily early morning (shortly after sunrise) sea turtle nesting surveys will commence on May 1 , 2003 and continue uninterrupted through September 15 , 2003 . Thereafter, monitoring will be conducted several days each week until the last marked nest has hatched . Surreys will be conducted using ATVs . All emergences (turtle crawls) apparent from the previous night will be interpreted to determine which species of turtle came ashore and whether or not it nested . Crawls will be denoted as being either above or below the previous high tide line . Only those crawls above the tide line will be included in data summaries and analyses . Nests and false crawls will be recorded by pre-established survey zones . These zones will be consistent with those established in the Biological Monitoring Plan for the project . Each false crawl will be categorized as to the stage at which the nesting attempt was abandoned in conformance with Florida Fish and Wildlife Conservation Commission (FWC) requirements for beach restoration projects . Additionally, all obstacles (e .g . , scarps , seawalls , etc. ) encountered by turtles during their emergences onto the beach will be documented . The location of each nest will be recorded using a hand-held GPS unit capable of determining positions to with 10- 16 feet (3-5 meters) of the actual geographic location . This data will be incorporated into EAI 's GIS database and nest distribution maps produced for inclusion in a year-end summary report . 4) Nest Marking. At least 75 loggerhead nests will be marked for the purpose of determining nest fate and reproductive success . The clutch of each marked nest will be located and surrounded by a series of small stakes connected by brightly colored surveyor's tape . Marked nests will be monitored throughout their incubation period to determine nest fate (e . g . , hatched , washed out, depredated , vandalized , etc. ) . After an appropriate incubation period , and in accordance with FWC guidelines , nests will be excavated to determine reproductive success . Nest contents will be assigned to standard categories (e. g . , unhatched eggs, dead hatchlings , etc. ) developed by FWC . Two measures of reproductive success will then be calculated : hatching success (the percentage of eggs in the nest that hatch) and emerging success (the percentage of eggs in the nest that produce hatchlings which successfully escape from the nest) . 5) Scarp Monitoring. Once each week between May 1 and September 15 , 2003 , the beach will be monitored for the presence of escarpments (scarps) . In accordance with FWC protocol , scarps will be functionally defined as an abrupt change in beach slope (greater than 450) that is at least 18 inches in height , and persists for a distance of 100 feet or more . Each scarp observed during the survey will be assigned to one of three categories (0 to 2 feet, 2 to 4 feet, and 4 feet or higher) . Additionally , the location of both the northern and southern terminus of each scarp will be noted relative to the nearest DEP reference monument. This information will be used to calculate the percentage of the total project area affected by scarps .
