Disease and pollution. The effects of disease and pollution on Chiricahua leopard frogs are poorly understood (USFWS 2000; Xxxxx 1999). However, chytridiomycosis has been implicated in the disappearance of Chiricahua leopard frogs from some areas, including stock tank populations in New Mexico in the 1980s (USFWS 2002, Sredl and Xxxxxxxx 2005), and ranid frog populations in southeastern Arizona are considered some of the most likely to have been affected by airborne pollutants from copper smelters in northern Mexico and southeastern Arizona (Xxxxxxxxx and Xxxxxxxxx 1987; Xxxx and Xxxxxxx 1988). The Agreement’s conservation program addresses the possibility of inadvertently transmitting disease into Chiricahua leopard frog populations as a result of translocations and cattle use (Sections 2.3.2 and 2.3.3). If, however, disease or pollution becomes a problem despite such efforts, it is difficult to predict what effects these factors may have on Chiricahua leopard frog populations within the covered area or what measures might be undertaken to address them. The Department and Participating Landowners will therefore address such issues, should they arise, as dictated by the severity of the problem, funding availability, technical feasibility, and scientific standards accepted at the time.
Disease and pollution. The effects of disease and pollution on the relict leopard frog are poorly understood (Service 2000b; Xxxxx 1999). However, chytridiomycosis has been implicated in the disappearance of leopard frogs from some areas, including stock tank populations in New Mexico in the 1980s (Service 2002b, Sredl and Xxxxxxxx 2005). The CAS conservation program addresses the possibility of inadvertently transmitting disease into frog populations as a result of translocations and monitoring. If, however, disease or pollution becomes a problem despite such efforts, it is difficult to predict what effects these factors may have on relict leopard frog populations within the covered area or what measures might be undertaken to address them. The Parties and Cooperators will therefore address such issues, should they arise, as dictated by the severity of the problem, funding availability, technical feasibility, and scientific standards accepted at the time.
Disease and pollution. The effects of disease and pollution on Chiricahua leopard frogs are poorly understood (65 Federal Register 37343; Xxxxx 1999). However, chytridiomycosis has been implicated in the disappearance of leopard frogs from some areas (65 Federal Register 37343), and ranid frog populations in southeastern Arizona are considered some of the most likely to be affected by airborne releases from copper smelters in northern Mexico (Xxxxxxxxx and Xxxxxxxxx 1987; Xxxx and Xxxxxxx 1988). The Agreement’s conservation program addresses the possibility of inadvertently transmitting disease into leopard frog populations as a result of translocations and livestock use (sections 2.5.3 and 2.5.9). If, however, disease or pollution becomes a problem despite such efforts, it is difficult to predict what effects these factors may have on leopard frog populations within the covered area or what measures might be undertaken to address them. The Service and Participating Landowners will therefore address such issues, should they arise, as dictated by the severity of the problem, funding availability, technical feasibility, and scientific standards accepted at the time.
