Post-fire native species seed mixes are effective at keeping out cheatgrass in the Great Basin

This longer-term study essentially shows that native seed mixes do well in suppressing cheatgrass in the Great Basin, even when compared to familiar conventional mixes that include the highly competitive nonnative crested and Siberian wheatgrass. The conventional seed mixes lived up to their reputation and were effective at keeping cheatgrass cover below 2 percent, but the native seed mixes were not far behind, with cheatgrass cover of 3 percent to 6 percent–in contrast to unseeded control treatments where cheatgrass cover reached 9 percent to 15 percent. And using native seed mixes may not be cost-prohibitive anymore—the scientists found that the price of native species seed has come down over the years to be much closer to that of introduced mixes.
