Mountain Lion Sighted Last Thursday

October 1, 2012

A mountain lion was sighted on the east side of McMillan Road between Buildings 6 and 71 at approximately 8:30 p.m. last Thursday. Mountain lions generally exist where deer are found. Warning signs have been placed at walkways and gate entrances. As a precaution, the use of isolated stairs and walkways at dusk, night, or dawn is discouraged. To limit an interaction with a mountain lion, avoid hiking or jogging in the undeveloped areas of the Lab alone or at dawn, dusk or night. If you see a mountain lion, immediately call 7-911 from any Lab phone or 911 from a cell phone. Go here for more safety information.

    Why not develop and install IR-based sensors to detect the passage of mountain lions through the lab? By determining how often and where something that moves at night/dusk/dawn that could be a mountain lion, the level of risk can be assessed, and safety measures can be improved. It seems to me that the Laboratory should make more of an effort to assess the frequency and presence of mountain lion activity. Steps such as movement-triggered lighting, which might prevent a serious incident, could be easily installed. At the moment, I think we, the Laboratory, are too passive about this risk.

    Given that the lab now has:

    1) some fairly isolated parking lots
    2) an increasing number of sightings (so perhaps bolder lions)
    3) many pedestrians and cyclists who may look like running deer
    4) quite a few shift workers arriving late at night or early in the morning
    5) we will soon be hosting an open house with many little people attending

    Is anyone else thinking we should consult wildlife experts as to whether it is advisable for the lab to host mountain lions on-site? Two years ago a mountain lion was shot when it was prowling in North Berkeley.

    I have worked night shift for the past 91/2 years and have never seen a mountain lion , let alone a mountain lion track or “kill ” .
    I am willing to bet that most or all of mountain lion sightings are mistaken identities.
