Field Trip to Playita Rosada

December 16, 2017

On Saturday, December 16, 2017, the Sea Grant Program of the University of Puerto Rico (UPR) conducted a field trip to Playita Rosada in La Parguera, Lajas. The participants in this trip were the 4H students from the Project Exploring solutions to environmental pollution sources in the Valle de Lajas watershed, led by Dr. David Sotomayor, a professor in the Department of Agro-Environmental Sciences at UPR in Mayagüez. During the trip, students had the opportunity to visit various stations where they learned about marine and coastal ecosystems. Mangrove trees, seagrasses, invertebrates, beach composition (sands), water quality, and basic meteorological concepts were the topics covered at the stations.

During the activity, participants studied the characteristics of the four types of mangroves found in Puerto Rico and identified them in Playita Rosada. They also analyzed various types of sands from different beaches in Puerto Rico and determined their composition. For this, they used a field microscope that helped them see the sand grains and their characteristics. At the seagrass and invertebrate station, they studied the difference between seagrasses and algae, and were able to observe, touch, and learn about different invertebrates inhabiting these ecosystems. Some of these invertebrates included green, red, and white sea urchins, sea cucumbers, starfish, among others. Furthermore, students analyzed the water quality of Playita Rosada, learning the meaning of each measured parameter and its importance for the survival of marine species. Finally, students analyzed various weather parameters using a portable weather station. They were also shown various instruments such as an anemometer and a rain gauge to learn how to use them. It was a very enriching and unique experience.
