factors during the surveys. More work is required to identify the problems and potential solutions for creating a useful data set to analyze the influence of such factors on the call abundance codes.

The potential to establish a long term amphibian monitoring network was established as a number of individuals wish to record their observations on an annual basis. Future efforts will be focused on establishing call frequency recording routes in those areas where sampling intensity was low, especially western P.E.I.

The records for the mink frog were based on calls. The volunteers used an audio comparison of dubbed recordings of the different species and the call could have been mistaken for that of another species. The relatively extensive surveys by Bleakney (1958) and Cook (1967) did not record this species, hence specimens or recorded calls are required for confirmation. An effort will be made to collect audio recordings of calls in these areas in 1995 to ascertain for certain whether the mink frog is present.

The computerized system proved to be quite useful in summarizing the data into maps and facilitates the collection of this data by volunteers. Now we need your help. Please review each of the species maps and advise us of any locations where you know each of these species to exist. Simply' drop me a note providing the details and this data can be added to provide a more complete picture.
