 If it’s Wednesday and I’m in El Monte, this must be the second day of the Watershed Council‘s Building a Healthy San Gabriel River Watershed conference.  I neglected to mention earlier that day one concluded with a very delicious dinner at the recently expanded Rio Vista Park.  I’ll blog about that park very soon.

Day two had plenty of informative speakers – a bit more focused, less broad than day one.  Irma Munoz, of Mujeres de la Tierra, spoke on doing real community engagement, not just minority outreach.  Irma tells it like it is – especially how critical it is that we listen to and respect our stakeholders.  Munoz got quite a few questions from agency staff who (it seemed to me) wanted her to reveal the secret trick to making connections with the community.  There’s no shortcut for real respect and transparency and knocking on doors.  Travis Longcore, of the USC Center for Sustainable Cities, spoke about the false dichotomy between cities and nature (and local impacts on the Loggerhead Shrike also called the Butcher Bird).  Ken Schwarz, an environmental restoration engineer for Horizon Water & Environment, discussed changing approaches to flood control channels urban streams, including hopeful examples from Napa, Sonoma, and Ballona Creek.  He brought up an interesting aspect that I think is underappreciated locally – integrated channel maintenance(!) and restoration. With all our integrated plans, there hasn’t been much focus on how go about maintaining existing channels and rights-of-way to better restore ecological functions… hmmm… there’s a whole blog entry that we could do with that one… soon.  Ellen Mackey, the Watershed Council‘s native plant guru  Senior Ecologist, spoke about the importance of emphasizing locally native plants.  She’s been instumental in coming up with the very-native LA River Master Plan landscaping guidelines, mapping vegetation on the San Gabriel River, and is also looking at that pesky maintenance issue – by coming up with a site-specific park maintenance manual for park staff and the community.  I will try to get my hands on this and share it soon on this blog.

Climate change was the subject of the second panel, with Rich Varenchik of the California Air Resources Board giving a broad overview of the state’s plan to implement AB32.  It mostly boils down to a much needed massive energy-efficiency plan (with some some smart growth and low impact development thrown in.)  For me, the most interesting speaker of the whole day was Stefan Lorenzato of the state Department of Water Resources.  Lorenzato spoke about how climate change is shifting how we look at watershed management.  In the unpredicability of future climates, he stressed that we should move away from monitoring for static goals, and look at “gradients.”  Our strategy should create rich resilient mosaics, not monocultures.  He connected this with a look at unpublished research that he’s involved in that shows the roughness of various stream channels.  It turns out that, at some flow volumes/speeds, some vegetation (ie: willows) turns out to be less rough (which is to say, allows more stream flow volume) than bare channels.  This means that some vegetation in a channel doesn’t necessarily reduce that channel’s capacity.  I will try to track this study down and blog on it, too (gotta keep a list of the promises I make here.)

The day ended with a media panel: Louis Sahagun of the Los Angeles Times, and Steve Scauzillo of the San Gabriel Valley Tribune.  They each spoke movingly of growing up along the then “lush jungle setting” of the San Gabriel River and how their journalism has brought environmental issues to light.  The creek freak bloggers could learn a thing or two from these veteran journalists… especially about getting out a good “summary lead.”  I have to work on that.

Changing Historical Alignments of the San Gabriel River

Lastly, here’s an image from Eric Stein’s presentation on day one of the conference.  I blogged on this before, but didn’t have the visuals to show you.  The maps on the left show how the course of the San Gabriel River has changed over time.  Click on the image to download the full 17MB SCCWRP report.

Well… there’s was quite a bit more that went on at the conference… but that’s my summary of the formal high points.  The best informal aspects of conferences being those times where I get to catch up with many of the other creek freaks from throughout the southland.  I’m grateful to and looking forward to more informative events from the Los Angeles and San Gabriel Rivers Watershed Council.
