nesting activity

The influence of factors that negatively affect nesting activity of sea turtles on Sint Maarten

Seven species of turtles are present in a wide range of areas across the earth. The species that use 
the beaches of Sint Maarten as nesting grounds are the Green sea turtle (Chelonia mydas), 
Leatherback sea turtle (Dermochelys coriacea) and Hawksbill sea turtle (Eretmochelys imbricata). 
Even with their protected status, populations are declining rapidly. This has a negative impact since 
sea turtles have significant ecological, economic and social values. To prevent populations from 
declining further, research is needed to create proper conservation strategies. This research focuses 
on different factors that could hinder nesting activity and how they influence sea turtles on Sint 
Maarten. These potential factors were researched in the literature and were determined to be 
artificial lighting, dune scarps, coastal development, slope, distance from high tide line to beach line, 
sargassum and human disturbances. Using a Spearman correlation test in SPSS, the correlation 
between the presence of these factors and the total nesting activity that takes place was tested. The 
test showed a moderate negative relation which was statistically significant 
(rs = -.681, p = .044). This means that the number of factors that are present at each beach influence 
the total nesting activity to some extent, but no strong correlation is present. These results indicate 
that if more factors which could hinder the sea turtle nesting activity are present, less sea turtle 
nesting activities take place on that beach on St. Maarten.
