Other claims from this paper (13)
- Observation Native understory species diversity increased with time since removal, with 18.2 native species recorded in 2012 and 28.2 in 2016.
- Intervention effect Diversity in revegetated plots did not differ from unplanted controls.
- Observation Of 22 planted species, 2 did not establish.
- Observation Native perennial grass, seeded species and annual bromes increased over time.
- Observation Nonnative forbs and native forbs decreased over time.
- Intervention effect Only invasive perennial grass cover responded to revegetation, being much higher in controls than in revegetated plots (25.7% vs. 7.7%).
- Mechanism The lower invasive perennial grass cover with revegetation was likely a response to a preplanting herbicide treatment.
- Observation All categories of species diversity except invasive species diversity increased over time.
- Observation Only 4% of Russian-olive stumps resprouted in the first year after removal.
- Observation Less than 1% of Russian-olive stumps resprouted 2 years after removal.
- Observation There was no Russian-olive emergence from seed in the removal year.
- Observation Russian-olive seed emergence varied exponentially among the years following removal.
- Observation Seeded native species did not have trouble establishing once adequate spring moisture occurred in the second growing season after Russian-olive removal.
