Population Status, Hunting Regulations, Hunting Activity, And Harvests Of Mid-Continent Sandhill Cranes, David E. Sharp, William D. Vogel
Proceedings of the North American Crane Workshop
The mid·continent population of sandhill cranes (Grus canadensis) was protected from 1916 until 1961, when hunting resumed on a limited basis. Areas open to hunting were experimentally expanded during 1961-72, but during the subsequent 1975-90 period only minor changes were made in the 8 Central Flyway states that established hunting seasons. Annual spring surveys conducted during 1982-90 indicated the population was stable at objective levels, with spring populations estimated at about 540,000 and fall flights near 590,000. Special federal hunting permits have been required for all bunters participating in regular seasons in the Central Flyway since 1975, where …

Managing Nature Reserves For Cranes In China, James Harris
Proceedings of the North American Crane Workshop
During the past 15 years, China has established more than 300 nature reserves. Many of the wetland reserves have been created primarily to protect endangered cranes. This paper summarizes the status of 22 nature reserves, 13 for breeding cranes and 9 for wintering cranes. The nature reserves have often been established in areas heavily populated or intensively used for economic purposes. Many reserves have been effective in stopping hunting of cranes. Taking of eggs or young has also been greatly reduced, but general human disturbances threaten successful nesting. Reserve authorities have also taken steps to prevent destruction or degradation of …
