Munz’s onion is a bulb-forming perennial herb. It was listed as endangered in 1998 as threats to the species included urban and agricultural development and clay mining activities. Those impacts have been reduced due to the implementation of the Western Riverside County Multiple Species Habitat Conservation Plan and other preceding HCPs.

Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.
