The biggest threat to build the beach is the loss of the nesting area (mosaic 389). Feeding the beach is another way to change the habitat of sea turtles. Feeding the beach where humans throw or pump sand on eroded beaches (mosaic 389). This usually happens only on the most advanced beaches.
Feeding on the beach is better than putting the beach together, but replacing the original nesting sites instead of preserving them (Mosaic 390). The beaches that have been fed can have high levels of mud, silt and carapace that make them too compressed for the children to leave the nest (Mosaic 390). The various elements in the sand or drip pump can have an effect on the sex of hatching; since sex is determined by temperature (Dobbs 390). The vehicles represent many threats to turtles in general.
Sea turtles are threatened by vehicles. Heavy vehicles on beaches can crush developing eggs and pre-emergent hatchlings (Musick 390). Tire tracks from vehicles can trap the young, leaving them exhausted and, therefore, easier prey for predators. “Loggerhead turtles can escape from a footprint of 3 cm in depth, but cannot escape from a rim groove of similar depth” (390).Perceived impacts are used as a basis for the translocation of nests (390). Pedestrian traffic has the potential to destroy marine nests and damage emerging offspring (391). In the past, human visitation during the night have been detrimental to the nesting of turtles and hatchlings, but “turtle watchers” have reduced this effect to a large extent.
Turtle watchers are volunteers who literally observe the nesting and hatching of turtles (391). They are providing educational and conversational potentials (391).”There are some indications that the strong economic incentive to attract a large number of tourists to some important nesting beaches may not coincide with the need to minimize the disturbance of nesting females and emerging hatchlings” (391). Artificial lighting can come from a variety of different sources; ranging from lamp posts to hotel rooms on the beach. Artificial lighting interrupts important behaviors, including the choice of the nesting site and the nocturnal behavior of the marine finding of both the offspring and the nesting females (391). Direct and indirect experimental evidence has shown that artificial lighting on beaches discourages sea turtles from nesting (391). Nesting that occurs around artificial lighting can have a high mortality (Klemens 108).
The young are attracted by artificial rays and are overcome by exhaustion, dehydration and predation (Klemens 109). “The effects of illumination vary with the lunar cycle and are greater during the period of the new moon” (109). There are many solutions for this enigma. Light sources may have lower wattage levels or be shielded, redirected, lowered, recessed or repositioned to protect the light from the beach (110). Yellow incandescent bulbs are a good alternative solution (110).
