25 Jul From the Field: Ríos Saludables Program Update
Blogpost written by Hilary Brumberg, Ríos Saludables Program Coordinator
Hello fellow nature enthusiasts! My name is Hilary Brumberg, and I am the new coordinator of the Ríos Saludables (Healthy Rivers) program. I just graduated from Wesleyan University in Connecticut a few weeks ago with a degree in environmental science and Spanish, and I am a Princeton in Latin America fellow.
My day-to-day activities here in the Osa Peninsula are very different from those in urban Connecticut. Each morning, I crawl out of my bug net and emerge among the mango trees on our organic farm. I chat with my fellow research field assistants over breakfast about their projects, ranging from releasing baby sea turtles to setting dung beetle traps.
Here in Osa, no two days are the same. I just finished June water quality testing at our community sites. This includes traveling around the peninsula, meeting dedicated conservationists and families who are curious about the effects of agriculture and roads on their neighborhood water source. The testing has allowed me to meet many friendly faces, including the manager of a farmers’ co-op, a town director of ecotourism, watershed managers, gardeners at an eco-lodge, and families concerned about the cleanliness of the rivers where their kids swim.
To study the river water quality, we examine both what is dissolved in the water (chemistry) and what is alive in the water (biology). We survey the rivers for our mighty mini-beasts, or macroinvertebrates, whose presence indicate the health of the river because they are sensitive to pollution. While chemical monitoring provides a “snapshot” of the water quality at the time of sampling, macroinvertebrates tell a story about what is happening in the stream over a period of time. Results of the chemical tests and macroinvertebrate surveys indicate that human land use negatively affects the water health.
I am designing a study to look at the effects of oil palm and teak tree farming on river health. Eventually, I plan to expand the study to examine how these processes affect important mangrove ecosystems. I am excited to spend the coming months exploring new rivers and ecosystems around the Osa Peninsula!
For those, such as myself, who love field research, data analysis, environmental education, speaking Spanish, looking for bugs, and splashing in rivers with kids, the Ríos Saludables is a perfect opportunity.
