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.

    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.

    Cortaderia selloana
    Cortaderia selloana pampasgrass; white pampasgrass

    Wind can carry the tiny seeds of these plants up to 20 miles. The massive size of each pampas grass plant with its accumulated litter reduces wildlife habitat, limits recreational opportunities in conservation areas, and creates a fire hazard.

    Spreads aggressively by seed into natural areas by wind, water, or vehicles. Fast grower; impedes the growth of locally native plant species and eventually takes over natural areas. Also raises fuel loads and fire frequency in natural areas. Is spreading rapidly in California. Existing research indicates that red varieties of fountain grass P. setaceum 'Rubrum' are not invasive.

Recommended Ornamental Grasses for the Sierra Foothills

  • Muhlenbergia rigens

    Muhlenbergia rigens
    Muhlenbergia rigens deer grass

    This large, perennial, California native has dense clusters of narrow, bright green leaf blades and tall, slender flower stalks. Bold enough to be used as a focal point of the garden, it also partners well with other perennials, flowers, and shrubs. Once established, deer grass is extremely drought tolerant and fits in well with a water-conscious California garden. Other Muhlenbergia species can also be good choices.

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 peppertree; California peppertree

    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.

    Although not commonly sold in nurseries, this tree is sometimes "shared" among gardeners. Tree-of-heaven produces abundant root sprouts that create dense thickets and displace native vegetation. 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.
