JOURNAL #3

On our trip to Steelhead Park, I observed Melia (assuming it is Melia azedarach: nonnative), Cockleburs (assuming it is Rough cockburs), Paper-flower (nonnative), Sugar bush, Mule fat, Fan palms (assuming it is Washingtonia robusta: nonnative), Black willow, Smooth sumac (introduced). Currently, the ratio between native and nonnative plants is 1:1. From my observations so far, as I move down the LA River, the more the plants turn from native species to nonnative species.
