Current burn recommendations for areas known to contain massasaugas include, but are not limited to: burning early in the spring before emergence, burning on days when the snakes are likely to be inactive, only burn when ambient temperatures do not exceed 10 C and that wetlands not be burned after May 15th (Johnson et al, 2000; Kingsbury, 2002).
Data logger placement was representative of refugia used by the massasaugas at this site during their active season.
Following emergence from overwintering sites (late April), eastern massasaugas were located in the study areas using visual encounter surveys and drift fences with funnel traps.
Following chi squared analyses, Bonferroni confidence intervals were created to determine if certain habitat types were preferred or avoided by massasaugas, considering all habitats individually (Neu et al., 1974; Beyers et al., 1984; White and Garrot, 1990; Kapfer et al., 2008).
Necropsy of the two dead massasaugas ruled out health complications as a cause of death and indicated that their deaths were a direct result of the fire.
To the Editor: During 2008, the ninth year of a long-term biologic monitoring program, 3 eastern massasauga rattlesnakes (Sistrurus catenatus catenatus) with severe facial swelling and disfiguration died within 3 weeks after discovery near Carlyle, Illinois, USA.
Hematology, plasma biochemistry, and serology of selected viral diseases in wild-caught eastern massasauga rattlesnakes (Sistrurus catenatus catenatus) from Illinois.
Characterizing the agreement among four ophidian paramyxovirus isolates performed with three hemagglutination inhibition assay systems using eastern massasauga rattlesnake (Sistrurus catenatus catenatus) plasma.
The mortality rates, based on total captures, of 0% for massasaugas and 1.04% for all snakes were much lower than expected relative to the figures reported by Durbian (2001) and Frese (2003) who found post-burn mortality rates of 21% for massasaugas and 85% for all snakes, respectively, after active season prescribed fires.
We conducted a pilot study to begin evaluating the use of pre-burn mowing to reduce or eliminate Eastern Massasauga (Sistrurus c.

The Eastern Massasauga is a state endangered species in Missouri (Missouri Natural Heritage Program, 2003) as well as a candidate species for listing under the United States Endangered Species Act (Szymanski, 1998 and Federal Register, 1999).
