CODES FOR ENVIRONMENTAL DATA AND SUMMARIES
mspecies = total number of individuals counted in May of current year
mindiv = total number of individuals counted in May of current year
mcumind = cumulative individuals counted in May from start to date
mcumspp = cumulative species counted in May from start to date
mobservers = number of observers in May count for current year
mwlktime = total amount of time observerse spent walking in May count for current year
mdrvtime = total amount of time observers spent driving in May count for current year
mtottime = sum of mwlktime and mdrvtime
mdaytemp = average temperature for day of May (C)
sumppt = total precipitation (mm) in June, July and August of current year (to see effect on counts, use data for previous year)
