Tree Species of California’s Bay Area  

The Bay Area is home to one of the most ecologically diverse urban forests in the country. Depending on the exact neighborhood you call home, the trees around your property may be nestled amid dry inland valleys, redwood groves, Mediterranean-style hillsides, or a densely developed urban area.

To help you better identify the trees growing on your property or choose species that will thrive in your landscape, we’ll outline some of the most important native and commonly planted trees found throughout the San Francisco Bay Area below.

Trees Native to the Bay Area

California’s Bay Area supports a remarkable range of native tree species, from towering conifers to gnarled hardwoods. The exact species composition varies significantly between coastal, inland, and montane environments, but the broader region supports dozens of native trees (as well as some shrubs that arguably grow large enough to be considered trees).

Native Bay Area Conifers

Conifers reproduce via cones and produce needle- or scale-like foliage. Many Bay Area conifers are evergreen and exceptionally long-lived, with some species adapted to persistent coastal fog and others suited to dry interior slopes.

1. Coast Redwood (Sequoia sempervirens) 
2. Douglas Fir (Pseudotsuga menziesii) 
3. Monterey Pine (Pinus radiata) 
4. Bishop Pine (Pinus muricata) 
5. Knobcone Pine (Pinus attenuata) 
6. Gray Pine (Pinus sabiniana) 
7. California Juniper (Juniperus californica) 
8. Incense Cedar (Calocedrus decurrens) 
9. Western Yew (Taxus brevifolia)
10. Monterey Cypress (Cupressus macrocarpa)   

Native Bay Area Broadleaf Trees

Broadleaf trees bear wide, flat leaves and produce seed-bearing fruits or nuts. Many Bay Area hardwoods — particularly our native oaks — are evergreen, though several riparian and montane species are deciduous.

1. Coast Live Oak (Quercus agrifolia) 
2. Valley Oak (Quercus lobata) 
3. Blue Oak (Quercus douglasii) 
4. California Black Oak (Quercus kelloggii) 
5. Canyon Live Oak (Quercus chrysolepis) 
6. Interior Live Oak (Quercus wislizeni) 
7. Oregon White Oak (Quercus garryana) 
8. California Bay Laurel (Umbellularia californica) 
9. Bigleaf Maple (Acer macrophyllum) 
10. Madrone (Arbutus menziesii) 
11. California Sycamore (Platanus racemosa) 
12. Black Cottonwood (Populus trichocarpa) 
13. Fremont Cottonwood (Populus fremontii) 
14. White Alder (Alnus rhombifolia) 
15. Red Alder (Alnus rubra) 
16. California Buckeye (Aesculus californica) 
17. Toyon (Heteromeles arbutifolia) 
18. Western Redbud (Cercis occidentalis) 
19. Pacific Dogwood (Cornus nuttallii) 
20. Arroyo Willow (Salix lasiolepis)
21. Red Willow (Salix laevigata)
22. Pacific Willow (Salix lucida lasiandra)
23. Scouler’s Willow (Salix scouleriana)
24. Sitka Willow (Salix sitchensis)
25. California Black Walnut (Juglans californica) 
26. Boxelder (Acer negundo) 
27. California Ash (Fraxinus dipetala) 
28. Elderberry (Sambucus nigra caerulea) 
29. California Hazelnut (Corylus cornuta var. californica)

Non-Native Trees Commonly Planted in the Bay Area

The Bay Area’s mild climate supports a tremendous variety of ornamental and exotic trees from around the world. In fact, many residential neighborhoods and historic estates contain more non-native trees than native ones. Some species perform exceptionally well in the region, while others struggle with drought stress, poor soil conditions, or pests.

Non-Native Conifers Commonly Planted in the Bay Area

Many non-native conifers were planted throughout the Bay Area during the late 19th and early 20th centuries as windbreaks, for timber production, to provide erosion control, or simply for their aesthetic charm. 

1. Canary Island Pine (Pinus canariensis) 
2. Italian Stone Pine (Pinus pinea) 
3. Japanese Black Pine (Pinus thunbergii)
4. Norfolk Island Pine (Araucaria heterophylla) 
5. Deodar Cedar (Cedrus deodara) 
6. Atlas Cedar (Cedrus atlantica) 
7. Leyland Cypress (× Cuprocyparis leylandii) 
8. Santa Lucia Fir (Abies bracteata) 

Non-Native Broadleaf Trees Commonly Planted in the Bay Area

The Bay Area’s Mediterranean climate allows for an enormous diversity of broadleaf ornamentals from Europe, Asia, Australia, and South America. However, some historically popular trees are now considered invasive or poorly suited for modern Bay Area landscapes.

1. Blue Gum Eucalyptus (Eucalyptus globulus) 
2. London Plane Tree (Platanus × acerifolia) 
3. Southern Magnolia (Magnolia grandiflora) 
4. Chinese Elm (Ulmus parvifolia) 
5. Japanese Maple (Acer palmatum) 
6. Crape Myrtle (Lagerstroemia indica) 
7. Sweetgum (Liquidambar styraciflua) 
8. Jacaranda (Jacaranda mimosifolia) 
9. Brisbane Box (Lophostemon confertus) 
10. Camphor Tree (Cinnamomum camphora) 
11. Silk Tree (Albizia julibrissin) 
12. Tree of Heaven (Ailanthus altissima) 
13. Privet (Ligustrum spp.) 
14. Black Locust (Robinia pseudoacacia) 
15. Chinese Pistache (Pistacia chinensis) 
16. European Olive (Olea europaea) 
17. Victorian Box (Pittosporum undulatum) 
18. Coral Tree (Erythrina spp.) 
19. Pepper Tree (Schinus molle) 
20. Loquat (Eriobotrya japonica) 

Choosing Trees for Your Bay Area Property: Important Considerations

The Bay Area’s environmental diversity means that successful tree selection requires more than simply choosing a species you find attractive. Factors such as fog exposure, wildfire risk, drainage, slope stability, soil chemistry, and long-term maintenance requirements should all play a role in the decision-making process.

• Choose species adapted to your microclimate. A tree that thrives in the cool, foggy neighborhoods of Berkeley or Mill Valley may struggle in the hotter and drier inland conditions of Walnut Creek or Pleasanton.
• Consider mature size carefully. Many Bay Area properties feature limited rooting space, steep grades, retaining walls, hardscape elements, and utility conflicts that become problematic as trees mature.
• Avoid invasive or overly aggressive species. Certain historically popular landscape trees can spread aggressively, cause ecological harm, and create management challenges over time.
• Think about wildfire resilience. In fire-prone portions of the Bay Area, species selection, spacing, litter production, and long-term maintenance all play an important role in defensible space planning.
• Evaluate drought tolerance realistically. California’s periodic drought conditions and water restrictions make species selection increasingly important, particularly for larger landscapes.
• Consider long-term structural integrity. Some fast-growing species develop included bark, weak branch architecture, or decay issues that require proactive management as they age.

As you can see, selecting the right trees for a Bay Area property involves balancing aesthetics, ecology, maintenance requirements, and long-term risk management. That’s why it’s often worthwhile to work with an ISA-certified arborist before planting new trees or redesigning an existing landscape.
