Between April and September 2008, 36 diurnal surveys were made in
Varadero, Mayorquina, Cayo Borracho and Cayo Sal (9 surveys by
each locality), at intervals of 15-20 days. Sea turtle tracks with/with
-
out nests were characterized as well as nest poaching and hatchling
emergence. We found that Varadero, Mayorquina and Cayo Borra
-
cho are frequently used by turtles for nesting. In this study 84 repro
-
ductive events, totaling 75 sea turtle body pits and 9 crawls. The re
-
ported nesting of the hawksbill turtle and the leatherback turtle was
verified and, the green turtle nesting was confirmed by first time at
Cayo Sal. Green turtles were accounted in 42 (51,19%) of the repro
-
ductive events, followed by the hawksbill turtle (n= 34, 41,48%) and,
the leatherback turtle (n= 2, 2,38%). Five nests or body pits (6%)
could not be identified (6%). Factors affecting sea turtle nesting in
-
clude tourism activities, artisanal fishing, the poaching of nests and
capture of adults. In our view the zoning established in the Master
Plan and Use Regulations of the Morrocoy National Park in 1995
should be upheld. Additionally, wemakesome recommendations for
future research and conservationof sea turtles in the protected area.

INTRODUCCIÓN
El Parque Nacional Morrocoy (PNM) está ubicado en la costa
noroccidental de Venezuela (10°47´12´´-10°59´20´´ N; 68°09´41´´-
68°22´36´´O), en el estado Falcón (Fig. 1) y se decretó en 1974, con
una superficie total de 32.090 hectáreas (República de Venezuela
1974, 1975, INPARQUES y MPPA 2007).
La información sobre la utilización de las playas del PNM por
las diferentes especies de tortugas marinas que están incluidas como
parte de los recursos biológicos relevantes (República de Venezuela
1995), no está actualizada y la disponible proviene de pocas observa
