IAC Secretariat Pro Tempore • Virgina, USA

This report is intended to provide the IAC Member Countries with a view of the index nesting beach data that has been provided as per the adopted IAC protocols for reporting nesting beach abundance information. The first version of this report was prepared by Dr. Jeffrey A. Seminoff delegate of the United States to the IAC Scientific Committee and his research assistant Mr. Matthew Steinwurtzel in 2014. This report was updated in 2018 by Ms. Luz Helena Rodríguez, IAC technical assistant with help of Dr. Jeffrey Seminoff. The report is included in the IAC Technical Document series CIT-CC15-2018-Tec.14

Introduction

During the 9th Meeting of the IAC Scientific Committee Meeting in Buenos Aires, Argentina, the IAC Scientific Committee Working Group on Nesting Trend Analysis reported the results of a study to examine the value of IAC Annual Report data for monitoring changes in nesting abundance for sea turtles in the IAC countries (Document CIT-CC10-2013-Tec.5; Selecting Index Nesting Beaches in the IAC Region and Data Collection Guidelines). The goals of this report were 1) to explain why the IAC Scientific Team recommends the use of real numbers instead of ranges for tracking or monitoring long-term changes in nesting abundance, 2) to describe the advantages and disadvantages of reporting only for nesting index sites rather than all sites in a country, and 3) to develop guidelines for determining which nesting beaches should be considered index sites within IAC countries. Based on this report, the IAC Scientific Committee agreed that for future IAC Country Annual Reports, each country will report real nesting numbers (versus ranges in numbers) and will provide this information for species- specific index nesting beaches in each country. During the 10th Meeting of the IAC Scientific Committee Meeting in Tegucigalpa, Honduras, the IAC Index Beach Working Group reported the results of a study to examine the value of IAC Annual Report data for monitoring changes in nesting abundance for sea turtles in the IAC Member Countries. During the meeting, each Scientific Committee Member was asked to provide a summary of the proposed index sites for each sea turtle species nesting in their country. At the 11th meeting of the IAC Scientific Committee, the first report was prepared with the goal that this report will be updated every five years. In line with this plan, the report was updated as part of the activities of the 15th meeting of the Scientific Committee. The current document summarizes all nesting data provided so far and provides a country-by-country and a species-by-species account of how nesting abundance has changed over the last nine years (2009-2018). This update includes information through 2018 or until the last season reported by each country. We recognize that nine years of nesting abundance data is insufficient for determining population trends, but by continuing with this reporting strategy we expect that more years of data will eventually allow for a strong understanding of population trends.

Summary and Recommendations

The goal of this report is to provide information on nesting beach abundance for all IAC countries that host sea turtle nesting activity. However, of the 13 total countries with nesting, data from only ten countries are included in this report. These data reflect nesting abundance for six sea turtle species that are distributed among 96 index nesting sites for which data were submitted. Graphical summaries of the data are provided by country, nesting beach, and species (Pages 8-34). Based on our preliminary analyses, we have developed a set of recommendations that we believe will help ensure that the IAC is best suited to recognize when changes in nesting abundance occur within the region that may have major conservation implications.

List of Recommendations

1. The IAC Scientific Committee recommends that IAC Countries provide real number data rather than ranges for nesting beach abundance, as this is the best way to evaluate changes in population status. The IAC Secretariat Pro Tempore should continue to encourage IAC countries to do so when filling out the information in the IAC Annual Report.

2. The IAC Secretariat Pro Tempore should encourage each country to provide the methodology for how they arrived at their nesting abundance values. This may include a short description of how they collected data each year and if so, what changes in their techniques have taken place since the previous data report. In addition, it is encouraged that information is provided regarding the beginning, end, and peak months of the nesting season for each species at each beach. Any changes in monitoring effort at the beaches should be reported at the time that data are provided to IAC.

3. The IAC Scientific Committee recommends that countries report numbers of observed females or number of clutches, as these are the two most reliable data forms. Other data types such as estimated females or emergence/track counts based on incomplete survey effort should be avoided. See IAC Document CIT-CC10-2013-Tec.5 for more information.

4. The IAC Scientific Committee recommends that countries maintain consistency in the index nesting beaches for which data are reported each year. See IAC Document CIT-CC10-2013- Tec.5 for more information.

5. The IAC Secretariat Pro Tempore encourages all countries to provide data for all index beaches for each year. Provision of partial data or abundance counts that do not have a standardized collection technique should be avoided. See IAC Document CIT-CC10-2013- Tec.5 for more information. When no data or only partial data are provided for any given index

CIT-CC15-2018-Tec.14 site, the Reporting Countries should provide a clear explanation for why all data were not provided.

6. The IAC Scientific Committee recommends that an update to this Index Nesting Beach Report is conducted every 5 years, with a final report submitted upon completion to the IAC Consultative Committee and the Conference of the Parties.

7. The IAC Scientific Committee recommends that the trend of green turtles in Galapagos (Ecuador), Isla Aves (Venezuela) and Tortuguero (Costa Rica) are observed closely, along with the conditions in foraging areas.

The Inter-American Convention for the Protection and Conservation of Sea Turtles (IAC) is an intergovernmental treaty which provides the legal framework for countries in the Americas to take actions in benefit of sea turtles. The IAC addresses the need to implement measures harmonized among nations, coordinate multilateral conservation and protection actions, and oversee the implementation of a regional agenda that will lead to the recovery of the six sea turtle species included in the treaty
