Is there a reason not to use polymer injection? The literature below may be of use. Also, your state wildlife agency, which may require a permit for such activities, may have preferences. Vicky Meretsky

I would prefer that the mark was identifiable in the field, at point of recapture. This frog is endangered so the more safe the mark is when given and through retention is highly desirable. I greatly appreciate any thoughts. John
