When Teddy Roosevelt, known to be both big game hunter and amateur botanical collector, was asked to give an account of his interest and experience as an amateur naturalist, he replied, “The former has always been very real; and the latter, unfortunately, very limited.” I imagine most of us amateur naturalists feel pretty much the same way: it’s nigh impossible to imagine knowing very many organisms to the species level with the latest count around 2 million named and millions more suspected.

So we amateurs fall somewhere on the spectrum between curious and crazed, seeking to manage the acquisition of knowledge in ways that personally give pleasure. Birders pursue life lists

On a still, hot morning, I head out of town to visit some friends who are transforming their own corner of heaven in northern Albemarle County. Vickie and Mark Gottlob live in a house they finished building four years along the North Fork of the Rivanna.  It sits on a wooded slope of Buffalo Ridge, named for the mammals that once roamed these parts.  The Gottlobs are working with Louise Finger of the Virginia Department of Inland Game and Fisheries to help restore habitat in the river for another species rarely seen here: the Jamesriver Spineymussel.

This is my third visit to the site. Before Louise and her team of heavy equipment operators arrived earlier this week, I had come up to visit the river “before” so I could better appreciate the changes “after”.  I had donned appropriate river wading gear and dropped down into one of the deeper holes.  With cooling water up to my waist, I could see the bank slumping steeply into the stream and showing the signs of instability even an untrained eye could see.  The Gottlob’s small floodplain pasture was being eaten away by storm flows and gravity, and all this dirt was settling in the river and clogging the very life out of it.  But there were solid gravel bars, mounded here and there with piles of small cobble left by chub and other nest-building species.  It had the potential to be good habitat for the spineymussel if it could be stabilized.

The Jamesriver Spineymussel is a rarely seen mollusk in our parts – but its influence has been felt for years

You know something is not right when you walk up to the edge of MeadowCreek behind Kmart off Hydraulic Road. The bank drops down vertically to the stream bottom where a small flow trickles over the rocks. You are not sure how close you can get because looking upstream, you can see places where high water flow from storms has tunneled into the bank leaving just a flap of grass, hinged and drooping over the edge like the unruly bangs of a boy overdue for a haircut.

And you’ve seen this kinds of washed-out bank everywhere in the watershed, and especially as you walk along the Rivanna Trails encircling Charlottesville. For years, you may have said to yourself, this can’t be right, all this dirt eroding away, headed downstream in a brown muddy mess.

But how do you ever go about fixing something like this? And can it even BE fixed?

There are markings on the pavement in front of my house on Oxford Road. Day glow green circles, yellow dots and dashes like a Morse-code message from the underground. Red and green marks, too. Up the dense periwinkle that hugs the slope between the curb and our lawn are bright blue lines sprayed 2 inches wide ending at the round cast iron water-meter. If I didn’t know better, I’d think it was some new kids’ game made permanent with the upgrade from chalk to spray paint.

But I do know better, because for last couple of months the street in front of my house has been busy
