I think the exhibit on Lincoln as a circuit lawyer in central Illinois is interesting. It's a nice but smaller county museum. The restored prairie on the west side of the property is interesting, but gets some spillover noise from the interstate.

Big Lincoln exhibit, blacksmith shop, small botanical garden, connects west to a restored prairie and east to a forested river corridor. It is very convenient off I-74.

He was just great. Everyone on Stax had the same excellent backing musicians, but Redding completely elevates the sound as a singer. I'm never tired of it.

This pool was packed with non-native virile crayfish; we recovered >120 in only four traps. It will likely dry out by the end of summer, but virile crayfish have dispersed through this intermittent reach. We found them abundant in the permanent stream higher up the watershed (photos 2 & 3).

This is a good prediction.

So ... any crayfish in this small and declining habitat?

They always are, from Australia to Madagascar to Canada

Here an abundance of crayfish claws and carapaces have been cleaned out of center pivot irrigation filters that had clogged. In our study region, many farmers and ranchers identify this as a problem, but I don't think anyone has quantified these type of impacts of invasive crayfish to agriculture.

The non-native virile crayfish (Faxonius virilis) in particular has boomed in regions of the western US without any native crayfishes like the Colorado River (nas.er.usgs.gov/queries/Fact...). Given its abundance in irrigated lands, I wonder if we're missing damages and costs as an ag pest?

I routinely get calls from water management districts in southern Idaho concerned about damage to canals from burrowing by this same non-native crayfish. In estimates of economic costs of invasive crayfish (doi.org/10.1016/j.sc...), I think we're missing effects on agriculture in the western US.

This was another barrier where non-native crayfish passage was obvious before we started sampling. Here a small gate in one of the water control structures was clogged with carcasses from the upstream pool. I think this barrier is open to flow at times of the year when crayfish are moving around.

Crayfish in the genus Faxonius (formerly Orconectes) differ enormously in their desiccation tolerance (e.g., doi.org/10.1111/j.13...). Terrestrial locomotion by crayfish also requires moderate temps w/high humidity (www.jstor.org/stable/1549337). That's rare in our study region in the summer.

However, the invasive crayfish we're working with is really intolerant of desiccation. Faxonius virilis is usually excluded from intermittent or ephemeral habitats by other species (doi.org/10.1086/725318). I think it's going to be reluctant to go over-land in this very arid region.
