[Pollinator] New videos on using and making glycol traps for native bees and mass painting of bee bowls.

[Sam Droege]

All:

We have just posted 3 new How-to videos.

1.  How to make a propylene glycol native bee trap holder

Cost = about 15 cents each

2.  How to deploy, run, and process a set of glycol traps

3.  How to quickly paint a lot of bee bowl traps

Note that we are in the beginning phase of establishing a network of 
glycol traps for long-term monitoring of bees.  We will gradually 
implement that throughout the this year.  Last year's pilot and 
recommendations are viewable at:

ftp://ftpext.usgs.gov/pub/er/md/laurel/Droege/Draft%20USFS%20Glycol%20Report%2022711.pdf

Which will soon be replaced by a final version.

Note that propylene glycol traps have the following advantages for 
monitoring bees and doing bee research

1.  They trap continuously and thus remove the effect of phenological 
shifts and the choice of trapping day on captures of bees and also require 
fewer traps to effectively survey a site.
2.  They are less work as they need only be filtered rather than bowl 
traps put out and then picked up.
3.  They can be incorporated into routine maintenance of weather stations 
and other periodic events and thus are easier for maintenance and 
technicians to man.

"Weather"

Weather, n. The climate of an hour. A permanent topic of conversation 
among persons whom it does not interest, but who have inherited the 
tendency to chatter about it from naked arboreal ancestors whom it keenly 
concerned. The setting up of official weather bureaus and their 
maintenance in mendacity prove that even governments are accessible to 
suasion by the rude forefathers of the jungle. 

              Once I dipt into the future far as human eye could see, 
              And I saw the Chief Forecaster, dead as any one can be-- 
              Dead and damned and shut in Hades as a liar from his birth, 
              With a record of unreason seldom paralleled on earth. 
              While I looked he reared him solemnly, that incandescent 
youth, 
              From the coals that he'd preferred to the advantages of 
truth. 
              He cast his eyes about him and above him; then he wrote 
              On a slab of thin asbestos what I venture here to quote-- 
              For I read it in the rose-light of the everlasting glow: 
              "Cloudy; variable winds, with local showers; cooler; snow." 

Halcyon Jones.
