Description

As the non-timber forest products industry increases on a commercial scale, the need for assessments of tree health and sustainability of these practices also increases. Harvesting birch sap for subsistence purposes has occurred for decades but commercial interests in this process and resource is expanding. In this evaluation, we review literature related to birch sap harvesting practices, report on a pilot study that assessed impacts to birch trees from sap harvesting, and review the “Best Practices” guidelines for tree tapping developed by the Alaska Birch Syrupmakers’ Association.
