Squawbush Sumac, sometimes also called Skunk Sumac

Description:

3-6 feet tall, rounded shrub. Leaves and new stalks are velvety to the touch. Lobed leaves are clusters of three. Turn red then yellow in fall. Tiny yellow flowers in spring leading to orange-red berries.

Habitat:

Found in chaparral and oak woodland and grassland areas. Seem most often to be growing right with scrub oak.

Notes:

I see them everywhere at Pioneer Park trail system
