>>443769yeah I'm not sure it's about learning out lesson as just not giving a shit. the DOT guys want plants that fit engineering specs, i.e. bomb-proof, aggressive with a tendency to form monotypic stands, and easy to grow. this paradigm is basically antithetical to responsible ecological management. ON THE OTHER HAND, biologists have yet to suggest a solution that isn't dramatically more expensive and failure-prone. caltrans is attempting to engage them and use e.g. native plants these days, but there are loads of problems with it -- eventually it all comes down to budget.
