Urban Ecology

Holm oaks are drought-tolerant Mediterranean trees increasingly planted in California cities, and tracking where they grow helps us understand which non-native trees are thriving — or spreading — as our climate shifts toward hotter, drier conditions.

A type of oak tree originally from the Mediterranean region was spotted and officially recorded in Davis, California. Called Holm oak, this evergreen tree keeps its leaves year-round unlike most oaks. Citizen scientists verified the sighting, adding it to a growing map of where this tree is showing up in North America.

Key Findings

1

A research-grade observation of Holm oak (Quercus ilex) was confirmed in Davis, CA — meaning multiple identifiers agreed on the species identification.

2

The location (Villanova Dr, Davis, CA) places this Mediterranean native in California's Central Valley, a region with a climate increasingly similar to the tree's native range.

3

The observation contributes to iNaturalist's open biodiversity database, which now holds millions of plant records used by researchers to track species distributions.
