Erosion Study by Field Research Intern

Planet Drum Field Research Intern Nicolas from France has recently completed a three month erosion study on the hills near Bahía de Caráquez.
Nicolas selected five areas to study (Bellavista, La Cruz, Km. 8, and behind the greenhouse at the Catholic University). Each area has two sites (measuring 8m by 8m), one with vegetation and one without vegetation.

Field Research Intern Nicolas and Planet Drum volunteer in training Xavier at the erosion study site (with vegetation) on the hillside above the Bellavista community.

At each site, a concrete bollard was poured, bamboo stakes were placed, gps coordinates taken, and precise measurements of the hills elevation were obtained using a surveying (dumpy) level in a grid of 81 points (9 by 9, every meter). For more details about this work, please see blog posts related to “Field Research”.

Nicolas, Orlando, and Xavier take measurements with the dumpy level at the Bellavista erosion site without vegetation.

Next year (and in subsequent years), more measurements will be taken in order to compare the rates of erosion over time at each site. This will allow for a precise measurement of the difference that vegetation makes on hillside erosion.

Nicolas worked diligently over long hours to make all of the necessary preparations, calculations, and field measurements. He has successfully initiated the first long-term study of erosion rates in the area.

This project is one example of how university students can put their environmental studies into practice while contributing to Planet Drum’s revegetation project.
