The latter option should be considered only after studies indicate that translocation will not jeopardize the Rota population and that snake-control measures on Guam are sufficient to predict higher than current levels of survivorship of aga on Guam. Given the fact that two aga populations are extant at present, the committee strongly recommends that comparative, experimental studies be conducted.

The committee strongly recommends that a comprehensive approach to snake control be undertaken. It should include the following actions: • Institute aggressive interdiction measures for snakes on Guam, such as exclosures in and around air and naval ports, to protect cargo going to Rota.

RECOMMENDATION 4 Place electric barriers on all nest trees to protect nests from brown tree snakes and monitor lizards, and increase trapping efforts in nest trees and adjacent areas. Test the effectiveness of nest-tree barriers, exclosure barriers, and trapping of brown tree snakes in increasing the rate of construction of nests and the production of viable eggs by aga.

RECOMMENDATION 6 Conduct annual censuses of the aga population on both islands about a month before the breeding season. Conduct a complete census of the population and map all territories.

RECOMMENDATION 8 As soon as possirle, develop and implement a habitat conservation plan for Rota that preserves essential crow habitat but allows economic development in an ecologically responsible manner. See "Past and Current Conservation Management: Rota" in chapter 2.

See "Past and Current Conservation and Management" in chapter 2 and "Finding 11" in chapter 4. RECOMMENDATION 11 Conduct a public education program that specifically addresses issues relevant to aga conservation, including the problems associated with the spread of the brown tree snake.

• Develop systems for monitoring, evaluating, and revising the program. Programmatic evaluations should be based on both internal review by staff and input from external target audiences and participants.
