CASPAR, California — With one exception, all the usual sounds of spring have returned to the Jackson Demonstration State Forest in Caspar. …But there is no sound of chainsaws and falling trees, and there is no chance of more tree-cutting for profit until 2025, possibly even later. A timber harvest plan that uses pre-burning and other environmentally favored techniques will be on the agenda of the Jackson Advisory Group (JAG) on May 8. Even if approved, that harvest would not begin before 2025. …The meeting will feature a new chairperson, Amy Wynn, and several members who have been reappointed. …The agenda includes a discussion of revamping the JAG charter, which could result in restructuring the JAG to solve the most vexing problem the advisory group faces, that of co-management. California Governor Gavin Newsom has pushed for Tribes to be part of managing the forest resources.
