Another benefit of the bamboo is that it spreads quickly and can choke out unwanted vegetation such as pine trees.
Dr. Nelson said that a closure cap vegetative cover will require more study than this nursery. "Soils are important and moisture balance and nutrient cycles are also important. We also need to understand more fully the early growth and establishment of the bamboo and its performance in closure cap conditions. But it seems promising at this time, pending further research."Bamboo also has shallow roots, so it can create this cap easily without getting into the deeper layers of soil.
