> On California's Santa Cruz Island, the honey bees needed to be eliminated to control invasive European weedy species.

This is a heavily freighted statement. Needed? By whom or what logic? The notion that non-native insects propagate non-native flowers is largely a myth, not supported by any science. Nativists have been telling these just-so stories for years and have gone largely unchallenged. Nature has no real distinctions such as native, invasive, and the like. These distinctions are created by conservationists and reinforce various biases colored by speculation and fantasy about the pre-Anthro world. See:
