Hydroseeding test plots

"As a continuation of our efforts to define, test and implement soil stabilization efforts in high mountain areas of the Guánica watershed in Puerto Rico, we performed stabilization techniques using number of different formulations to determine best practices. The formulations were based on the results of a Exposed Soil Roundtable held earlier this year in the upper watershed with representatives from plants, soils, restoration, agronomy and erosion and sediment control experts from NRCS, FWS, NOAA RC and NC State University. Our first test plots were chosen on one large and varied site associated with the re-routing and reconstruction of part of a road on PR-355 above the town of Yauco was chosen due to the large area of exposed soils as well as the varied slopes and aspects that were exposed. The area was also a priority based on rainfall, slope and exposed soils; it scored as a high priority site in our prioritization analysis. In this update, we discuss and show photos of the plots pre-stabilization, during stabilization and poststabilization (after 3-4 weeks post-stabilization) and provide initial lessons learned and measures of effectiveness -- though ultimately the effectiveness will be gauged over a longer duration"--Page 2. 2012 CoRIS (Coral Reef Information System) Library Public Domain 1858
