The Peninsula splits into three tree zones. On the coastside (Pacifica, Montara, Half Moon Bay), blue gum eucalyptus groves shape the canyons, with Monterey pine and cypress through the older neighborhoods and willows in the creek corridors – salt wind and steep ground stress everything equally. In the hills (Belmont, San Carlos, Hillsborough, La Honda), coast live oaks dominate the woodland with redwoods and Douglas fir in the deeper canyons. On the bayside flats (Burlingame, San Mateo, Foster City, Palo Alto), mature street trees, estate oaks, and ornamentals fill compact lots.

The species mix explains most of our work: eucalyptus weight reduction near homes, retiring 60 to 70 year old Monterey pines weakened by pitch canker, protecting native oaks, and keeping healthy trees pruned so the winter wind finds nothing loose to take.
