San Jose State University 7/8/9th June 2023

In early June 2023, a lively group of students from San Jose State University took a break from their usual academic environment to embark on an unforgettable journey to the heart of Puerto Rico’s rainforest. Staying from the 7th to the 9th, these young conservationists turned their hands to vital work at Las Casas de la Selva, focusing on the crucial task of landslide mitigation.

The lush, vibrant landscape of the rainforest is as beautiful as it is fragile. Recent landslides had left scars on this verdant canvas, posing threats to the forest’s rich biodiversity and to the trail system that allows us humans to witness its wonders. To help counter this threat, the San Jose State University students prepared berms for a special guest – Vetiver, or Chrysopogon zizanioides, a plant with extraordinary soil-stabilizing properties.

With shears in hands and determination in hearts, the students trimmed slips of vetiver, and planted the slips 6” apart. The task was labor-intensive, but there was an underlying excitement – a sense of being part of something larger, something impactful. As they worked, they learned about the fascinating characteristics of this humble grass that make it an unsung hero in the fight against soil erosion.

The vetiver plant is a marvel of nature, with a root system that is finely structured and robust. Despite its seemingly delicate appearance, the plant’s roots can penetrate 3–4 meters deep within just the first year of growth, forming a strong subterranean network that safeguards the soil above. Vetiver is unique, as it neither develops stolons nor rhizomes, making it incredibly drought-tolerant.

But perhaps the most significant characteristic of vetiver is its ability to protect soil against erosion. Where other plants might succumb to the onslaught of wind and water, vetiver stands tall, its deep roots acting as a living barrier against the destructive forces. In the event of sediment deposition, new roots can sprout from buried nodes, demonstrating an incredible resilience that further underscores its value in conservation efforts.

Watching the San Jose State University students planting vetiver, it was clear that this was not just a hands-on learning experience, but a meaningful contribution to the preservation of the rainforest. Their time at Las Casas de la Selva was a testament to the critical role that we, as individuals and communities, play in safeguarding our planet’s natural resources. It was a demonstration of how knowledge, action, and passion can come together to create lasting, positive change.

Thank you to Kirky (Kristine Kirkendale) who led the team, and to Globalworks International who organized the expedition. Karaya Diaz provided excellent cuisine for the team.
