Cement-Lock. Miyawaki invented this process, and whatever I understood of the methodology I wrote it as a standard operating procedure, so it could be replicated, says Sharma. Reduced impact logging (RIL) is the intensively planned and carefully controlled implementation of timber harvesting operations to minimize environmental impacts on forest stands and soils. From that manual, a would-be forester learns how to determine soil type using the ribbon test; how to collaborate with a local nursery to find truly native species; how to prepare the planting site; and how to arrange saplings, three to four per square meter, into a grid.
