please be sure that there is no vegetation in front of the camera, or near the camera that may grow to obstruct the
camera during the 30-60 day period it will be out. Taking care to ensure proper set up is key, particularly if cameras
cannot be checked for long periods of time. Cameras should be set to record a burst of 4 images on each detection,
with a one minute delay between successive triggers. If a camera model being used doesn't have this option, that is
OK, but it must be noted on the data sheet. If placed in areas where theft is a possibility or that will have lots of
human traffic, then cameras should be placed in such a way to make them less visible as much as possible (e.g.,
slightly set-back from the travel pathway), without compromising image quality, field of view (camera can 'see'
across the entire trail), and infrared sensor detection. Please use the test function on the camera to make sure the
camera-trap has a decent cone of detection, both in length and width, in relation to the trail where movement
will occur. Python cable locks should be used to secure cameras in all areas, although these are a visual deterrent
only, and will not stop a committed thief. Cameras should be left to run for at least 60 days. If possible, a 30-day
check for camera functionality should be performed. During this check, the camera should be checked for sufficient
battery life, position, and functionality, and the SD card swapped out, or the image data downloaded. Remember to
make sure the cameras is turned on prior to leaving the area!!
*Note: We have not found baiting with scents to be particularly effective in improving lynx detection at cameras.
Given that scented pads also add the complication of needing to set out and refresh baits, I have elected to not use
scented baits as part of this protocol.
Data management: When cameras are initially set out, please record all relevant data on the "Camera Set-up" data
sheet.
At the 30 or 60 day check, please download all image data to a folder labeled with the name of the camera, and
whether or not this is a 30day_1st, 30day_2
nd
, or 60day_download. Thus, the name of a folder that was
downloaded after a 30 day check might be CamID_234_30day_1
st
. A folder of images that was downloaded after
the second 30 day check, might be CAmID_234_30day_2
nd
. A folder of images that was downloaded after 60 days
(there was no 30 day check) would be labeled as CamID_234_60day. I with provide an external hard-drive for
image storage, although I recommend saving the image folders to at least two separate locations (the external hard
drive and a local computer). If the SD card is not going to be reused, images can be left on the card (in addition to
being downloaded to a computer), and the card left in the camera. If the SD card is going to be redeployed, please
erase the images before redeployment. I will engage with each of you to obtain the SD cards and/or image folders
upon completion of the 90 day sampling period.
