Wildlife Monitoring
Project 1. Relict Leopard Frog Monitoring, Management, and Research
- Fall surveys completed at all natural and translocation sites.
- Coordination for a potential translocation site on BLM lands in the Gold Butte area ongoing – the aim is that this site will be ready for translocations in 2008.
- Coordination ongoing for evaluation of a translocation site on BLM lands in the Black Mountains, AZ – the plan is to complete compliance in 2008.
- Coordination and assistance provided to UNLV research efforts on habitat improvements at Blue Point, Rogers, and Pupfish Refuge springs.
- Relict Leopard Frog Conservation Team meeting held in December. …

Wildlife Monitoring
Project 1. Relict Leopard Frog Monitoring, Management, and Research
- Diurnal and nocturnal surveys completed at all natural and translocation sites during the spring – the most striking finding was the lack of frogs observed at Rogers Springs and lower Blue Point despite repeated survey efforts.
- Relict leopard frog annual translocation effort completed – a total of 1365 late stage tadpoles and 592 post-metamorphic frogs from the head-start facilities were released at existing translocation sites.
- Mark-recapture effort at Rogers Spring abandoned because of the lack of frogs; assistance provided for a mark-recapture study at upper Blue Point Spring.
- Potential translocation sites …

Wildlife Monitoring
Project 1. Relict Leopard Frog Monitoring, Management, and Research
- Spring-time diurnal surveys for relict leopard frogs were conducted at all sites.
- Relict leopard frog annual translocation effort was initiated. Currently, 2,153 tadpoles are being reared at the Hill Top and Willow Beach Fish Hatchery facilities. Quagga mussels found at the hatchery might not be as problematic for this program as originally thought. Current prophylactic protocols for disease treatment in tadpoles and frogs are being evaluated for their ability to kill quagga mussel larvae.
- Coordination and monitoring was provided to EPMT crews conducting tamarisk control at relict leopard frog sites in …
