Other information crucial to wildlife management, such as herd size and mortality estimates, are researched or prepared and shared among agencies interested under the co-management arrangements.

The Treaty Council employs a wildlife biologist who maintains a comprehensive conservation program for a variety of species. The biologist monitors game population sizes and trends, and conducts telemetry studies to determine home range and habitat use. Tribal fish and game committees use information from these studies to adopt science-based hunting regulations. The biologist also provides technical expertise and policy analysis to better address tribal wildlife conservation efforts.

Research and management are coordinated with government agencies and other tribes. Population and harvest monitoring data are shared with the Washington Department of Fish and Wildlife and with neighboring tribes. These parties meet several times a year to exchange information and cooperatively develop recommendations for hunting regulations. The Treaty Council also routinely consults with federal agencies to coordinate management of threatened species, migratory birds and marine mammals.

Like non-Indian hunters complying with state law, tribal hunters must comply with the hunting regulations adopted by their tribes. They are required to carry a tribal hunting license, and must obtain permit tags for each big game animal they wish to hunt. Tribal hunters may hunt only within restricted seasons and bag limits. They must tag big game animals and submit harvest reports to their tribe. All tribal hunters carry photo identification cards that include their name and tribal affiliation.

In the region of Washington ceded under the Treaty of Point No Point, big game harvest by PNPTC tribes make up only a small fraction of the total. Between 2003-2008, PNPTC tribal hunters harvested 119 elk, compared to state hunters who harvested 1,043 elk; tribal hunters harvested 265 deer while state hunters harvested 12,553 deer.
