  1. Griffith Park Wildlife Daniel S. Cooper Cooper Ecological Monitoring, Inc. Pasadena, California

  2. Park geography Next exit Introduction to major habitats 1/4 mi. Griffith Park critters 1/2 mi. The Fire of 2007 3/4 mi. Threats to Griffith Park 1 mi.

  3. GRIFFITH PARK GEOGRAPHY 1 2 Burbank Griffith Park 134 Fwy. Forest Lawn L.A. River/ I-5 H’wood Reservoir 101 Fwy. 5 3 4 Hollywood/Los Feliz

  4. 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”

  5. 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

  6. 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

  7. 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).

  8. MAJOR HABITATS OF GRIFFITH PARK: “Rock Outcrops” Unique gardens of lichens and succulents. Largely inaccessible (with a few exceptions). Poorly-studied.

  9. 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,

  10. 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

  11. 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

  12. CHARACTERISTIC SPECIES OF GRIFFITH PARK Plants 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 LilyBrush/Spring Cyn. c. 20 plants in park (Clockwise, from upper left): Leptodactylon californicum, Clarkia bottae, Dudleya lanceolata, Keckiella cordifolia

  13. 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 individuals And, possibly 18 others known from eastern Sta. Monica Mtns.

  14. The Fire of 2007 - assessing the effects Most/all habitat types affected No unique habitat affected 800+ acres transformed (not “lost”) Wake-up call

  15. THREATS TO WILDLIFE AND HABITATS Identify: “problem spots” “problem forces” Popular trailheads Interior picnic areas Exotic/Invasive species Off-leash dogs
