Fish Inventories
Fish inventories were conducted in five Northern Great Plains Network parks for purposes of documenting at least 90% of the species expected to occur there. The parks were: Devils Tower and Scotts Bluff National Monuments, Mount Rushmore National Memorial, Fort Laramie National Historic Site, and Wind Cave National Park. Although Wind Cave National Park had adequate existing information, the park was included to determine if the plains topminnow was present in the park .
The fish inventories were conducted using seining and backpack electro-shocking. Voucher specimens were collected.
