Refuge regulations, hunt brochures and federal maps use a vocabulary of their own. Here are the terms you’ll see most often, in alphabetical order.
A–C
Acquisition boundary (approved refuge boundary). The line within which the U.S. Fish and Wildlife Service is authorized to acquire land for a refuge. It often includes private inholdings the government doesn’t own. Being inside the boundary doesn’t mean land is public.
Archery-only unit. A hunt area where only bows (and sometimes crossbows) may be used — common near roads, buildings and visitor areas.
Bag limit. The maximum number of a species you may take in one day. Refuges follow state bag limits but can set lower ones.
Baiting. Placing feed, salt or other attractants to lure game. Hunting over bait is prohibited on National Wildlife Refuges, and federal baiting rules apply to migratory birds everywhere.
Blind (draw, permanent, portable). A structure or cover you hunt from. Draw blinds are assigned by lottery; permanent blinds are built by the refuge; portable blinds are brought in by hunters and often must be removed daily.
Check station / check-in. A place or system where hunters sign in, receive assignments or report their harvest.
Closed area (sanctuary). Land closed to hunting. Waterfowl sanctuaries give birds a safe place to rest, which keeps them in the area.
Conservation easement. A permanent legal agreement in which a landowner sells certain rights (such as the right to drain wetlands or plow grassland) to the government. The land remains private; easements don’t provide public hunting access.
Coordination area. Land owned by the U.S. Fish and Wildlife Service but managed by a state wildlife agency under an agreement, usually under state rules.
D–H
Duck Stamp (Federal Migratory Bird Hunting and Conservation Stamp). Required for waterfowl hunters 16 and older. Revenue buys habitat for the refuge system. See the Duck Stamp guide.
E-Stamp. An electronic version of the Duck Stamp sold through state license systems, valid for a limited period until the physical stamp arrives.
Fee title. Full ownership of land. Fee-title refuge land and WPAs are federally owned public land.
50 CFR Part 32. The section of the Code of Federal Regulations containing general refuge hunting and fishing rules and refuge-specific regulations for each refuge.
Flyway. One of four broad migration corridors used to manage waterfowl: Atlantic, Mississippi, Central and Pacific. Federal season frameworks are set by flyway.
HIP (Harvest Information Program). The registration required for all migratory game bird hunters in each state they hunt. See the HIP guide.
Hunt brochure. The refuge’s summary of hunting rules and maps, often also serving as a permit. See how to read one.
Hunt unit. A mapped area of a refuge with its own hunting status and rules.
Huntable status. The status of a hunt unit in the national USFWS dataset: Yes (open), Special Regulations Apply (open with refuge-specific limits) or No (closed). See Hunt unit status explained.
I–P
Inholding. Private land inside a refuge’s acquisition boundary.
Legal shooting hours. The times when hunting is allowed. For migratory game birds, generally one-half hour before sunrise to sunset. See the shooting hours guide.
Lottery (draw). A random drawing for limited permits, blinds or hunt dates.
Migratory game bird. Birds covered by federal migratory bird hunting regulations: ducks, geese, brant, swans, coots, doves, woodcock, snipe, rails, gallinules and sandhill cranes.
Moist-soil unit. A wetland impoundment where water levels are managed to grow natural waterfowl foods such as smartweed and millet.
National Wildlife Refuge (NWR). Federal land managed by the U.S. Fish and Wildlife Service primarily for wildlife conservation. Hunting is one of six priority public uses, allowed where compatible with each refuge’s purpose.
National Wildlife Refuge System. The network of refuges, wetland management districts and other units managed by the Service.
Nontoxic shot. Shot approved by USFWS as safe for wildlife — required for waterfowl nationwide and for other game on many refuges. See the nontoxic shot guide.
Plugged shotgun. A shotgun limited to three shells total, required for migratory bird hunting.
Possession limit. The maximum number of birds or animals you may have in possession at one time, typically a multiple of the daily bag limit for migratory birds.
Prairie Pothole Region. The glaciated grassland of the northern Great Plains, dotted with shallow wetlands — the heart of North American duck production and home to most WPAs.
Q–Z
Quota hunt. A hunt with a limited number of hunters, usually filled by lottery or first-come registration.
Recreation.gov. The federal reservation website many refuges use for permits, lotteries and reservations.
Refuge permit. A permit required by a specific refuge in addition to state licenses. In our data, 187 refuges require one.
Signed brochure. A free refuge permit consisting of the hunt brochure, which you sign and carry.
Special regulations. Refuge-specific rules that apply on top of state regulations, such as limited species, dates, weapons or access.
Split season. A season divided into two or more segments, common for waterfowl and doves.
Upland game. Non-migratory birds hunted on land, such as pheasant, quail, grouse, prairie chicken and partridge.
Waterfowl Production Area (WPA). A small federally owned wetland and grassland tract, usually managed by a wetland management district and generally open to hunting under state rules. Browse the WPA directory.
Wetland Management District (WMD). A USFWS office that manages WPAs and easements across several counties.
Youth hunt. A hunt reserved for young hunters, often with a mentor. 79 refuges list youth opportunities — see youth hunts.
Zone. A geographic part of a state with its own season dates, common for waterfowl, deer and turkey.
