not previously recorded. Carefully fill out all of the other information requested
on the data sheet. Include relevant notes on the location and accessing it for
people who will be servicing the camera trap. A few photographs of the area and
the approach might be useful for this as well.
Flagging: If needed to find the location surveyors flagging tape can be used to
help mark the location but don't rely on it because it can disappear and there
may be flagging out there unrelated to our project. Be careful about placing
flagging that could give away our camera locations for security reasons.
Use your judgment as to whether flagging is necessary and where and how
much to use.
Scent Lures and Imported Attractants
Some CWMP remote camera traps utilize imported attractants including bait,
scent lures, visual attractants, and auditory attractants. Guidelines for the specific
types of attractants are outlined in the species specific protocol documents.
Below are some general considerations relevant for all uses of scent lures and
other imported attractants on CWMP remote camera traps.
General application of scent lures: Find two trees (or a tree and a rock, log or
other feature the camera can be aimed downward at), about 10 feet apart; one
tree that is both large enough to mount the camera on and sturdy enough that it
won't sway too much in breezes. The other tree or landscape feature is for
spreading the lure on and can be any size, but make sure it is large/sturdy
enough though to withstand animals rubbing and leaning against it and that the
camera is angled properly to aim toward that area. Apply the attractant at a
height where the target species can inspect it.
Scent lure can also be attached higher on a tree trunk or overhanging branch
where it will catch the wind and travel further, acting to draw in animals from a
longer distance.
Trapper's lures: With the highly concentrated trapper's scent lures (those in
small bottles) remember a little goes a long ways. Simply use a branch dipped
into the bottle for application, and drop a few drops at the base of the tree. You
can apply some to the bark of the tree as well and hang the "lure twig" there or
insert it in the bark, but do remember moderation.
With fish oil, fish fertilizer, or oil from a sardine can, you can apply the scent more
liberally by pouring some with the aid of a branch lower on the tree and also
higher, creating an oil slick that will remain on the tree through rain events.
Aiming the remote camera: Placing the camera about 10 feet from the lure
tree/feature (or even a little farther out depending on the angle of the camera) is
best for most camera models to avoid cutting off or only capturing portions of
