Survey of
Main Stem of the Millers
For Rare
Odonates 10 May 2004 PurposeSurvey Protocol
A series of 21 survey stations has been established along
the main stem of the Millers, from just above its confluence with the For each station, surveyors should report odonates observed
anywhere along the stretch of river 300 yards up- and downstream of the access
point. Surveyors do not have to
cover all of this 600-yard stretch on each survey.
Odonates observed up to 15 meters (50 feet) perpendicular to the bank
should also be included in the survey. If
possible, both banks of the river should be surveyed at each station.
Odonates observed beyond these boundaries should not be included as part
of a standard survey, but should be reported separately. To the extent possible with volunteer surveyors, each station should be visited by a surveyor for a minimum of one hour per two-week period from mid-May 15 through early October (a total of 10 such periods) at least once in a three-year period (2004-2006). A web site will be established and updated regularly so all surveyors can know if a particular station has been surveyed for a given period. Obviously, the more a station is surveyed, the better, but surveyors should attempt to survey unvisited stations before repeatedly surveying any one site.
2) Netted and released, by experienced observer. Photographs taken by less-experienced observers and identifiable to species are also coded here. 3) Adult collected, or identifiable photograph taken. Note that to collect state-listed odonates, surveyors need a collecting permit from NHESP, which is easily obtained. Members of the Athol Bird & Nature Club may collect under Dave Small’s permit, if their collecting is part of this survey. 4) Oviposition observed, tandem pairs observed, exuviae or nymphs collected, or very recent tenerals (preferably associated with their exuvia). Collection of exuviae from listed species does not require a permit from NHESP. The surveyor should fill out one survey form for each hour spent surveying. Thus, if two hours are spent surveying at one station consecutively, the surveyor should fill out two forms, one for each hour and keeping separate the observations from each hour. This will allow the survey data to be analyzed statistically, to some extent. Observations (of any sort) of listed or watch-listed
odonates from elsewhere on the Millers mainstem or its tributaries are of
interest, as well, since they will help illuminate the extent of a species’
use of the river or its tributaries. These
observations can be submitted on a These are more-or-less self-explanatory.
Surveyors are encouraged to tell the coordinators of any suggestions for
making this, or any other document associated with this survey, easier to use
and understand. On the form, please
use the station number and name as assigned by the coordinators.
All observers should be listed, with the person filling out the form
listed first. Temperature need not
be precise, but please be as specific as possible.
For wind speed, please use the Beaufort scale numbers (appended), unless
you have precise data from the site of observation.
Sky cover need only be described as sunny, partly cloudy, or overcast.
Surveyors may look for nymphs in the rain, if they are that obsessive,
but not for adults or tenerals. A
light rain may be suitable for surveying for exuviae; use your own judgment.
For survey time, put the time of day (i.e., As so little is known about odonates, surveyors are encouraged to note any details of behavior (such as oviposition sites, substrates where nymphs were found, methods used to find nymphs, type of prey, emergence sites and distance from water, etc.). Such observations may greatly expand our knowledge of each species. List of Station Names, Numbers, and Directions for Access

Species/Sex Combinations Identifiable by
Sight Alone
Note:
this list is quite conservative and only notes those expected along the
Millers;
many competent observers can ID many other species by sight alone.
An X in a box indicates that a sight record for a species of that sex is
acceptable.
