Don’t Plant a Pest! Sierra Foothills

Invasive Ground Covers of the Sierra Foothills

  • Hedera spp (ivies)

    Hedera helix
    Hedera helix English ivy

    Some ivy species in the Hedera genus are a problem in California. They can smother understory vegetation, kill trees, and harbor non-native rats and snails. It's difficult to distinguish problem species from less invasive ones. Do not plant ivy near natural areas, never dispose of ivy cuttings in natural areas, and maintain ivy so it never goes to fruit. Researchers hope to determine which ivies can be planted safely.

    Vinca major periwinkle; bigleaf periwinkle; greater periwinkle; blue periwinkle; myrtle

    This aggressive grower has trailing stems that root wherever they touch the soil. Their ability to resprout from stem fragments enables periwinkle to spread rapidly in shady creeks and drainages, smothering the native plant community.

Invasive Ornamental Grasses of the Sierra Foothills

  • Arundo

    Arundo donax_Giant reed_ JM Di Tomaso
    Arundo donax
    Arundo donax giant reed

    This grass grows along streamsides, where it can reach over 20 feet tall. It grows in dense thickets that clog waterways and is a fire hazard. When clumps of arundo are washed downstream during storms, they become trapped against bridges and create a maintenance problem where they land. Arundo creates less shade than the native trees it replaces, increasing water temperatures to a level that is dangerous for native fish.

Grows quickly, creating a fire hazard in residential landscapes. "Sterile" varieties haven't been independently verified or tested and are not recommended as substitutes.

    "Sweet broom" (Cytisus spachiamus or Genista racemosa) is not known to be invasive. However, because we lack information on its potential for invading wildlands, we do not recommend it as a substitute for other brooms.

    Schinus molle_Peruvian peppertree_JM DiTomaso
    Schinus molle
    Schinus molle Peruvian pepper tree; California pepper tree

    Pepper trees are native to South America (despite the fact that Peruvian peppertree is sometimes called California peppertree). Seeds are transported by birds and mammals into natural areas. The aggressive growth of peppers enables them to displace native trees and form dense thickets in natural areas. They produce undesirable suckering and sprout unwanted seedlings. A serious problem in southern California. Less of a problem in the San Francisco Bay Area and Central Valley, but care should be taken if planting near wildlands.

These root sprouts can be produced as far as 50 feet away from the parent tree. In California, it is most abundant along the coast and Sierra foothills, as well as along streams. A single tree can produce up to a million seeds per year.
