Griffith Park

MAJOR HABITATS OF GRIFFITH PARK:“Southern Mixed Chaparral”

Dominated by evergreen shrubs, most of which are found only in California (Ceanothus, Toyon, Chamise, Mtn.-Mahogany).

Fire-dependent

High species diversity

“Aquired taste”

Page 5: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

MAJOR HABITATS OF GRIFFITH PARK:“Oak Woodland”

Shady groves in canyons and terraces along streams.

Dominated by 1 species (Coast Live Oak)

Fire-tolerant

Wildlife magnet

People magnet

Page 6: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

MAJOR HABITATS OF GRIFFITH PARK:“Sycamore Woodland”

Towering trees (Western Sycamore) along streams and former stream courses.

Largely converted to picnic areas within park.

Fire-damaged

Wildlife magnet (esp. birds)

People magnet

Page 7: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

MAJOR HABITATS OF GRIFFITH PARK:“Coastal Sage Scrub”

Low-growing scrubland on loose, eroding soils; dominated by species found only in California.

Fire-maintained, but destroyed by frequent fire.

High plant, animal diversity (esp. reptiles and butterflies).

Page 8: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

MAJOR HABITATS OF GRIFFITH PARK:“Rock Outcrops”

Unique gardens of lichens and succulents.

Largely inaccessible (with a few exceptions).

Poorly-studied.

CHARACTERISTIC SPECIES OF GRIFFITH PARK:Reptiles/Amphibians

All widespread terrestrial Santa Monica Mtns. species present and common.

One (?) aquatic species (Pacific Treefrog)

Still need to determine status of:- Side-blotched Lizard- Western Toad- Arboreal Salamander- Coast Horned Lizard- “Rare snakes”

Striped Racer, Western Whiptail Pacific Treefrog,

Page 10: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

CHARACTERISTIC SPECIES OF GRIFFITH PARK:Mammals

All widespread large and mid-sized mammals of Santa Monica Mtns. species resident (except Mountain Lion)

Populations likely inflated by feeding, dumping, and landscaping.

Still need to determine status of most/all small mammals (e.g. mice, shrews)

Bobcat, Gray Fox, Raccoon

Page 11: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

CHARACTERISTIC SPECIES OF GRIFFITH PARK:Birds

Most bird species of Santa Monica Mtns. present in proper habitat.

# of riparian birds along canyons depressed; likely due to degraded habitat.

Limited “infiltration” of urban birds into park interior (= a good thing!)

Purple Finch, Rufous-crowned Sparrow, Western Bluebird

Page 12: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

CHARACTERISTIC SPECIES OF GRIFFITH PARKPlants

Eastern extension of Santa Monica Mtns.

Locally-rare species scattered; along streams, on rock outcrops, within dry scrub, etc.

Native flora historically viewed as “problem,” fixed through planting exotics.

Research ongoing (R. Fisher, City of L.A.)

Humboldt Lily Brush/Spring Cyn. c. 20 plants in park

(Clockwise, from upper left): Leptodactylon californicum, Clarkia bottae, Dudleya lanceolata, Keckiella cordifolia

SENSITIVE SPECIES OF GRIFFITH PARK

WILDLIFE (per DFG)“Ashy” Rufous-crowned Sparrow - Arid slopes and roadcuts, esp.

buckwheat. 20+ pairs in park.

Yellow Warbler - 5+ pairs nest in willows along L.A. River channel.

California Legless-Lizard - recorded vic. L.A. Zoo in sandy soil; #s?

Coastal Western Whiptail - Arid scrub; 100s in park.

Coast Horned Lizard - Historical only?

PLANTS (per CNPS)Calandrinia breweri - historical records from Vermont Cyn. (pictured)Lilium humboldtii - Fern, Brush Cyns.Berberis nevinii - probably derived from planted individualsAnd, possibly 18 others known from eastern Sta. Monica Mtns.

The Fire of 2007 - assessing the effects

Most/all habitat types affected

No unique habitat affected

800+ acres transformed (not “lost”)

Wake-up call

Page 15: Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

THREATS TO WILDLIFE AND HABITATSIdentify: “problem spots”

“problem forces”

Popular trailheads

Interior picnic areas

Exotic/Invasive species

Off-leash dogs
