Native Plant: PURPLE NEEDLEGRASS (Stipa pulchra) Nitrogen deposition + Fire + Managed Grazing + Two-year drought + Habitat clearing - Reproduce! 0 Heather Schneider

A perennial bunchgrass native to California. It can tolerate drought by growing an extensive, deep root system that can be up to 20 feet deep. It is called “needlegrass” because the seed is pointed and sharp like a needle and Native Americans used them to teach children to weave baskets.

Native Plant: CALIFORNIA POPPY (Eschscholzia californica) Nitrogen deposition + Fire + Managed grazing + Two-year drought + Habitat clearing + Reproduce! + Heather Schneider

A California native annual that provides beautiful spring wildflower displays. It produces 1000’s of seeds per plant in fruits that are explosively dehiscent (burst open on their own). This is the state flower of California. The species is invasive in Chile! Plant family: Papaveraceae (poppy family) References: Leger, E.A. and K.J.

Native Plant: Elegant Clarkia (Clarkia unguiculata.) Nitrogen deposition - Fire + Managed grazing - Two-year drought + Habitat clearing - Reproduce! + Heather Schneider

Native annual wildflower that is endemic to California (it only occurs in CA). Clarkia unguiculata has purple pollen and is pollinated by specialist bees, most of which are solitary (do not live in a hive). Another name for this species is “farewell to spring” because it is often one of the last species to flower in the late spring. Many species in the Clarkia genus have been bred for horticultural use because the flowers are so showy. Plant family: Onagraceae (evening primrose family) References: Baldwin, B.G. and D.H.

Native Plant: VALLEY OAK (Quercus lobata) Nitrogen deposition + Fire + Managed grazing + Two-year drought + Habitat clearing - Reproduce! 0 Lynn Sweet

This oak tree is one of the largest species of oaks in North America. It is endemic to California (does not occur anywhere else). Woodlands containing valley oak support 67 nesting bird species, including the threatened Swainson’s hawk. Unlike some California oak trees, valley oak is deciduous. Valley oak can withstand wildfires. Plant family: Fagaceae (beech family) References: Gaines, D. A The valley riparian forests of California: their importance to bird populations. In A.

Invasive Plant: BLACK MUSTARD (Brassica nigra) Nitrogen deposition + Fire + Managed grazing - Two-year drought - Habitat clearing + Reproduce! ++ Heather Schneider

Black mustard is an invasive annual wildflower in much of the USA. It is native to the southern Mediterranean region in Europe. It has been grown for thousands of years in Europe and Asia as a spice. It can form dense stands that are near monocultures and outcompete native wildflowers. It can be controlled using mechanical means (hand-pulling) or herbicide.

Invasive Plant: RIPGUT BROME (Bromus diandrus) Nitrogen deposition + Fire - Managed grazing - Two-year drought - Habitat clearing + Reproduce! ++ Heather Schneider

Ripgut brome is an invasive grass in much of the world. It is native to Mediterranean Europe and is a widespread invasive in California. Its seeds are sharp and can lodge themselves in animal paws, eyes and noses. It is a fierce competitor of native annual wildflowers, perennial grasses and potentially even tree seedlings. It increases the frequency of wildfires and can re-establish its populations following fire. It can be controlled using prescribed burning (fire) if the fire is set when the seeds are on the plant but have not dropped yet. It is also susceptible to herbicide.

Invasive Plant: FENNEL (Foeniculum vulgare) Nitrogen deposition + Fire - Managed grazing + Two-year drought + Habitat clearing + Reproduce! + ©Neal Kramer

This large perennial plant is native to Mediterranean Europe and highly invasive in California. It is highly aromatic and tastes like anise. The swollen bulb can be eaten as a vegetable. It is in the same family as carrots and dill. It is difficult to remove once it invades because it must be cut down and sprayed with herbicide or dug up and thrown away.

Invasive Plant: REDSTEM FILAREE (Erodium cicutarium) Nitrogen deposition + Fire + Managed grazing + Two-year drought + Habitat clearing + Reproduce! ++ Heather Schneider

A small annual herb that was introduced as part of the initial settement of the Western U.S., possibly associated with introduction of livestock by the Spanish. It is native to the Mediterranean Basin. It produces copious numbers of seeds, spreads rapidly, and can form mats of vegetation that limit germination and sprouting of native species. It is widely distributed in California. Plant family: Geraniaceae (geranium family) References: Brooks, M.
