Long-Term Monitoring by the LUQ-LTER

The Luquillo LTER monitors several variables on a long-term basis to assess natural patterns and changes due to hurricanes and other disturbances. Among those variables are climate, flowering and fruiting phenology of common trees, stream water chemistry and discharge, and animal populations (shrimp, coqui, lizards, snails, insects).

Luquillo Forest Dynamics Plot (LFDP)

The LFDP was marked and set aside as a long-term forest dynamics plot in 1990.  Its dimensions are 500 x 320 m or 16 hectares. The plot is routinely monitored to assess populations of shrubs, trees, and animals, investigate natural disturbance patterns and land-use legacies, and understand changes in tree community composition and diversity.  Periodic censuses of plants, animals, and environmental conditions are the only activities allowed within the plot.

The Canopy Trimming Experiment

The CTE actually consists of two experiments—one on mechanisms of resilience to hurricanes and one on impacts of more frequent hurricanes. The first experiment focuses on a key process in resilience: post-hurricane decomposition, which is affected by the change in microclimate when the canopy is opened, by the deposition of canopy debris on the forest floor, and by the activity of various organisms that feed on the debris. The treatments are designed to separate and quantify the effects of these factors.
