On January 31, 1748, a Royal Ordinance of the Ministry of the Navy was published, containing silvicultural instructions that were innovative for their time. It mandated the marking and location of mountain nurseries based on sun exposure and protection from prevailing winds. It also regulated the method for hilling acorn plantations, established permits for harvesting on private timberlands, and required the marking of trees using dendromorphic technical criteria for use in the naval industry. The Royal Ordinance for the Governance of Timberlands under Navy Jurisdiction applied to all forests located within 25 leagues of the coastline and navigable rivers.
