northeastern Chorus Frogs
Pseudacris triseriata



As soon as Fred Schueler left home to attend university in New York in the 1960's, and then in Canada in the 1970's, he was entranced by the creaking call of the Striped Chorus Frog, Pseudacris triseriata, which he had not heard during his youth in Connecticut.

Since then he's been fascinated by the strikingly definite distributional limits in this species' range both in northern Ontario (P. t. maculata and the northeastern populations of the "Western" or "Midland" subspecies, P. t. triseriata, in (as now mapped by their respective herpetofaunal atlases) Northern Ontario, southern Ontario, New York, Vermont, and Quebec.

In 1973 Fred and Aleta's courtship featured surveys of the distribution of this species in western and northern New York and Fred and his late brother Paul Wesley Schueler discovered the species in Vermont in 1975. Since then we've always recorded Chorus Frogs wherever we've heard them.

Since 1990, in many places it has seemed to us that the species has been declining, a sentiment Fred expressed in his review of a report on the species' status in Quebec (Canadian Field-Naturalist 113(4):699) , and now, with the co-operation of many others who are concerned about these declines:

This page was moved to the pinicola website in February 2006, with some updating of changed URLs. The EOBM has since failed in unfortunate circumstances, and we've taken over many of its functions at the BMNHC. New information about Northeastern Chorus Frogs is listed at a Chorus Frog News page, and results of monitoring Chorus Frogs on a surveys page.

the status of northeastern Chorus Frog populations

The Eastern Ontario Biodiversity Museum announces a meeting of friends and students of Pseudacris triseriata, to discuss Chorus Frogs in central Canada and the northeastern United States - 3-4 March 2001, in Kemptville, Grenville Co., Ontario, Canada.

First Annual International Conference on Northeastern Pseudacris triseriata

(thanks to Dave Seburn of Seburn Ecological Services for the grandiose title, though there are no present plans to make this an annual event)

Despite its vernacular, the ‘Western' Chorus Frog, Pseudacris triseriata triseriata, is found farther east than any other Chorus Frog, though this eastern range was discovered, in Quebec and Vermont, only in the 1950's and 1970's. But in many places where it was found in those decades, it is now absent. Even in areas like central southern Ontario, some observers feel that choruses are much more widely scattered than they were in the past. In the first five years of the Marsh Monitoring programme, this was the only anuran that significantly declined in frequency in the Great Lakes Basin (Weeber & Vallianatos. 2000. The Marsh Monitoring Program 1995-1999).

Relatively suddenly, there was a lot of Chorus Frog work planned: Jean-François Desroches beginning a master's project on year-round habitat use, Seburn Ecological Services analysing Ontario records, James Gibbs at Syracuse resurveying New York sites where Chorus Frogs were heard in the 1970's, and the EOBM planning to resurvey sites in eastern Ontario and the outer Bruce Peninsula. There are also questions about the status of the northeastern-most populations of the Boreal Chorus Frog, P. t. maculata, along the James Bay shore of Quebec, and the White River & Thunder Bay areas of Ontario.

In early January, 2001, we began a simple-minded e-mail list (i.e. REPLY ALL or send messages to bckcdb@istar for resending to everyone who's joined the list), discussing work with Ontario/ New York/ New England/ Quebec Chorus Frogs, and this group decided a meeting would be useful. We had two roundtable sessions, Saturday afternoon, 3 March, and Sunday morning, 4 March, at the EOBM, in which each of us presented what we'd found out about Chorus Frogs, or what we're planning to do.

This meeting resulted in a resolution expressing our concern for northeastern Chorus Frogs, and laying out a programme of actions we feel are necessary to understand and conserve them, and a collection of papers given at the conference or contributed by those who couldn't attend. If you're interested in northeastern Chorus Frogs - or are undertaking any of the actions suggested by the resolution - you can still join the e-mail list by writing to me at bckcdb@istar.ca. - F. W. Schueler - 10 March 2001

posting and maintenance of these Chorus Frog pages was supported by a contribution from Environment Canada.
