There's a lot to cover here, and there's at least one topic about which we may want to have an extended discussion -- the claim put forth in Schlaepfer et al. that we ought to take advantage of non-native species for conservation purposes. There's a good chance we won't finish everything we want to say about invasives on Monday, but a lot of this fits into the broader topic of ecological restoration anyway, so I don't think we'll fall too far behind.
