The first bird I formally identified, as in “sat down with the book and then wrote down the result” was a great blue heron. The entry in the old family Peterson Field Guide to Western Birds, red ball point pen: 11/86 Sat on tiny island in Colorado River all morning, picking at its feathers The …
Reconciliation ecology, the field’s founders say, “says we still have time to save most of the world’s species. But to do it, we must stop trying to put an end to civilization and human enterprise. Instead, we need to work on the overwhelming bulk of the land — the places we humans use. We need …

PHOENIX – Drive south on Interstate 10 out of the Phoenix metro area, past Ikea, and the city ends abruptly, a sharp line between development and desert. Given its reputation for sprawl, Phoenix (when I say “Phoenix” here I’m talking about the whole metro area, not just the city itself) is remarkably compact. The realities …
I’m working this weekend on two talks, one a webinar Wednesday with Audubon and the other a lecture for UNM Water Resources grad students Thursday, that both touch on one of the fundamental challenges in getting water management right – the question of how we draw the boundaries, both geographically but also conceptually – around …
I’ve praised the successful shift from flood irrigation toward more efficient technology – meaning things like center-pivot and drip over flood irrigation – that has enabled a downward trend in the amount of water applied to a typical irrigated acre of farmland in the United States. According to the USGS, US farmers decreased their average …

There’s an important point I try to make when I’m out in public talking about the 2014 Colorado River Delta environmental pulse flow: the amount of water used and the size of the landscape that got wet, compared to the once-vast delta, is tiny. I get excited about the pulse flow, when water managers on …
Audubon is looking to hire someone to help save the Salton Sea. It’s a great twofer – you get to help the birds, and if you succeed you also get to help save Colorado River manage as a whole, as the two are integrally related. If we fail to get the Salton Sea right, everything …

When I’m in Phoenix, I always try to squeeze out some time to go birding at the Gilbert Water Ranch, a constructed wetland where practical water management has been turned into a lovely urban amenity. A fascinating new project by Arizona State University graduate student Riley Burnette (pdf) attempts to quantify the role that the …
I joke that I kept trying to leave the Salton Sea out of my book, because it’s such a hairy problem that in threatened to derail me in so many ways. Of course I failed, because the Sea is a critical piece of solving the distributional problems of scarce Colorado River water. Agricultural reductions in …
This guy’s been ’round the place the last couple of days, I think lookin’ for love. Spring.
