That's date of domestication for the Eastern Woodlands, not the South West.
And while Crane may be off about the decline of large animal prey as a potential factor accelerating towards more farming (that prey already being long gone) the basic concept is possibly true - fresh water mussel populations declined significantly around the time that maize production took off. Directionality is the question. Did agricultural practices cause the decline or did declines due to climate change increase the reliance on agricultural practices?
Or a mix.
