36 CFR § 242.16 - Customary and traditional use determination process.
(a) The Board shall determine which fish stocks and wildlife populations have been customarily and traditionally used for subsistence. These determinations shall identify the specific community's or area's use of specific fish stocks and wildlife populations. For areas managed by the National Park Service, where subsistence uses are allowed, the determinations may be made on an individual basis.
(b) A community or area shall generally exhibit the following factors, which exemplify customary and traditional use. The Board shall make customary and traditional use determinations based on application of the following factors:
(1) A long-term consistent pattern of use, excluding interruptions beyond the control of the community or area;
(2) A pattern of use recurring in specific seasons for many years;
(3) A pattern of use consisting of methods and means of harvest which are characterized by efficiency and economy of effort and cost, conditioned by local characteristics;
(4) The consistent harvest and use of fish or wildlife as related to past methods and means of taking; near, or reasonably accessible from, the community or area;
(5) A means of handling, preparing, preserving, and storing fish or wildlife which has been traditionally used by past generations, including consideration of alteration of past practices due to recent technological advances, where appropriate;
(6) A pattern of use which includes the handing down of knowledge of fishing and hunting skills, values, and lore from generation to generation;
(7) A pattern of use in which the harvest is shared or distributed within a definable community of persons; and
(8) A pattern of use which relates to reliance upon a wide diversity of fish and wildlife resources of the area and which provides substantial cultural, economic, social, and nutritional elements to the community or area.
(d) Current determinations are listed in § 242.24.
