Attendees must bring:

-headlamp (at least one), good for distance (bright), and all batteries they will need. Brand new if coming from Washington or from the SW mainland or from eastern NA; but well decontaminated otherwise.

-optional: leather gloves that fit tight but allow finger mobility (e.g. deerhide) and are brand new or never used on bats before.

-small backpack or hip bag that can be easily decontaminated

-large-medium backpack for carrying gear

-a change of field clothes including any coat and boots/shoes, as the clothing worn in the field cannot be worn in vehicles; eg. arrive at site, change, and then change again at end of night. OR arrive in clean field clothes, and change at end of night.

-clean hip/chestwaders and rubber boots
-optional: coveralls (it may be too hot for these)
-optional: hardhat/caving helmet (a mine may be accessed, TBA)

-Attendees are strongly encouraged to gradually change sleep patterns prior to the course, generally not going to sleep until midnight at the earliest and getting up around 9 am or later.

-Attendees MUST show proof rabies vaccination or sufficient blood titre within the past 2 years.  YOU WILL NOT BE ALLOWED TO HANDLE BATS WITHOUT THIS.

-Food is not supplied in this course, and breaks during the classroom day will be short, so plan to bring snacks – after Day 1 note that specific meal-times will become less obvious as the course goes along!

-A computer (PC) is strongly recommended to visualize and process acoustic recordings of bats

-participants should bring at least 3 boxes of disposable latex, or vinyl gloves of the appropriate size for them
-because mistnets are easily snagged, please consider your field clothing carefully:  avoid shirts that have buttons on sleeves, bags/backpacks with buckles, etc.

(While there are free camping opportunities in the area, remember that Lillooet is very hot in the summer and so you will need to have sufficient shade to allow you to sleep in during mornings.)
