Guzzlerpalooza

Wildlife guzzlers collect water so it's available to wildlife in arid areas. They are normally installed to attract and increase game species, but all wildlife benefits. A number of different designs have been utilized through the years, making maintainance interesting.

an original "walk-in" design, with its apron covered in snow; these guzzlers are being converted to prevent unintended issues of animals becoming trapped in the tank

this walk-in (installed in 1966!) has been converted, with a drinker installed below (not in the photo)

	this photo shows a typical drinker, installed below "flying saucer" collectors
	looking down on the "flying saucers" and me hard at work!
	yet another design, this one simply collects water on the top that funnels into the tank

Pinyon-Juniper Removal

I'm sorry I haven't kept up with the blog! A number of factors have contributed, including a busy time of year, not as many new tasks now that I've settled in a bit, and less time in the field. I doubt you'd be entertained much by descriptions of cleaning up GIS data or updating mailing lists. But I'm trying...

A few weeks ago we had contractors removing single-leaf pinyon (Pinus monophylla) and Utah juniper (Juniperus osteosperma) in portions of our resource area. Both species naturally occur here, so why are we removing them?

Although the species historically occur in particular places, both pinyon and juniper have increased their ranges by invading sagebrush and other plant communities. This invasion is believed to have been facilitated by grazing, unnatural fire regimes, and climate change. The conifers displace sagebrush and shade out forbs and grasses, decreasing biodiversity. They also provide perches for raptors hunting Greater Sage-grouse (Centrocercus urophasianus), and the grouse have been shown to avoid invaded areas.
