 Overview 

October - December 2009
After a very bad year in 2008-2009, we had a good start this season. We have already identified 32 turtles and 9 of them are new recruits to the population. We have had more turtles during this period from October through December than in the whole season last year, and we still have half of the season left.

Additionally, three of the turtles seen have nested in seven different previous seasons, which is the first time such an event has ever been recorded. Two of these turtles were marked in 1994 and the other one in 1995, so this is a great success.

One of the turtles that participated in the Great Turtle Race I came back this year with good health condition. The dry season has arrived early and the conditions are those normally seen in March. Unfortunately, this is not good news for the turtles that frequently abort the nest because of the dryness of the sand.

We are hoping for a good second half of the season!

January 2010
This season has already been met with great success.  We have identified 39 individual females thus far.  Fifteen of those females arrived on Playa Grande without any sort of identifying PIT tags.  This means that we have never seen these turtles on this beach before, and therefore, they are new recruits to the nesting population. These females are, perhaps, the survivors of hatchlings released on the beaches of Parque Nacional Marino las Baulas 15-20 years ago!  We have so far seen more individual females at this time than were seen in total last year. 

Our beach hatchery, where nests laid in locations in danger of devastating tidal wash, holds 22 nests this season.  From those 22 nests we have had 12 nests hatch, producing a total of 346 hatchlings. This production of hatchlings and emergence of many new and return nesting females gives us renewed hope for the years to come.
