The Hubbard County Natural Resource Management Office oversees the resource management of 137,910 tax forfeited acres. This amounts to nearly 22 percent of the total 630,555 acres of Hubbard County land. Aspen dominates in the forests of Hubbard County; jack pine is the second most abundant species. In the early part of this decade, the county suffered a large jack pine budworm outbreak that made it necessary to harvest approximately 6,000 acres of its jack pine type. This problem, coupled with a severe browsing of jack pine seedlings by white-tail deer have made management of the county's jack pine and Norway pine difficult and challenging.
