According to Alana Chargualaf, Science Communicator for the Guam Green Growth Initiative, approximately 1,500 new trees were planted to help to combat erosion.

The trees contribute to a healthier watershed from the Ugum River in Inalåhan following a tree-planting event last month.

Volunteers assisted the effort, led by the Guam Restoration of Watersheds initiative from the University of Guam Sea Grant program.

Without trees, loose sediment flows downstream through watersheds, resulting in the destruction of vegetation, depletion of land mass, an accumulation of sediment in nearby rivers and reefs, and loss of wildlife over time.

The areas upstream of the Ugum River are examples of this — having become badlands over time due to a combination of negligent off-roading, arson, and feral herbivores feeding on vegetation, according to Teddy Concepcion, GROW team lead and a UOG Sea Grant extension assistant.

To restore a healthy Ugum ecosystem and watershed and for the badlands to thrive and potentially be cultivatable in the future, it will need increased plant biodiversity and rehabilitated soil.
