One of my writing projects for Friends of the Migratory Bird/Duck Stamp has been to assemble profiles of National Wildlife Refuges across the country that owe their existence to the Duck Stamp. For many of our NWRs, virtually all of the property was both or leased with money from the Migratory Bird Conservation Fund, and the money that hunters pay for Stamps goes into the MBCF.
To date, I have written up Camas NWR in Idaho, Bosque del Apache NWR in New Mexico, and Tamarac NWR in Minnesota.
Our target audience is mainly the birding community and bird-inflected readers, but I do slip a little natural history from other realms into my descriptions.
