Site Description
Río Yahuecas (GUIL) is an aquatic NEON field site located in the central-western mountainous area of Puerto Rico. This site was formerly named Río Guilarte. Río Yahuecas site is a 2nd order, wadeable stream with a watershed of 9.5 km2 (2350 acres), comprised of agricultural lands and subtropical moist/wet forest. The NEON sampling reach of Río Yahuecas is located in a montane area with steep slopes, though large boulders stabilize the channel within the municipality of Adjuntas. Access to sensors and sampling locations in the reach of Río Yahuecas are located within the surrounding land, which is an agricultural research station owned and operated by the University of Puerto Rico – Mayaguez Campus. This location is part of the NEON Atlantic Neotropical Domain (D04), which includes the island of Puerto Rico and the southern tip of Florida. The Domain includes two terrestrial field sites and one additional aquatic field site.

Geology
Río Yahuecas is part of the Anon Formation, which consists of interbedded andesite (volcanic) breccia, rhyodacite, sandstone, and siltstone.
Soils
The river lithology is mainly of the Anon formation: interbedded andesite or volcanic breccia, rhyodacite, and sandstone or siltstone of the Upper Eocene. Río Yahuecas substrate consists of a heterogeneous mixture of cobble, pebble and sand and large boulders are a dominant feature of the stream’s substrate regime.
Hydrology
Río Yahuecas's watershed is comprised of agricultural lands and subtropical moist/wet forest. The flow regime in Río Yahuecas is typical of Puerto Rican streams draining rainforest catchments; characteristic discharge exhibits a strong seasonal pattern with low flows during the mid- to late- dry season (December through March) and high base flow discharge during the annual wet period (May through November). Extreme high flow events may ensue because of tropical storms or hurricanes, which typically occur between June and December. This NEON site’s reach is located in a montane area with steep slopes, though large boulders stabilize the channel and several large, slow-moving pools. Aside from large boulders, Río Yahuecas substrate consists of a heterogeneous mixture of cobble, pebble, and sand.
