Introduction
The Stunt Ranch Santa Monica Mountains Reserve officially
joined the UC NRS in November 1995, becoming the system's 32nd site and the only one
administered by the Los Angeles campus.
This 67-acre site is located four miles
inland on the north central flank of the Santa Monica Mountains, southernmost of
California's Transverse Ranges. Situated less than a 45-minute drive from UCLA, about
midway between the cities of Malibu, on the coast, and Calabasas, on the inland side of
the mountains, the Stunt Ranch Reserve offers an important resource for teaching,
research, and public education in the midst of the heavily urbanized Los Angeles area.
In 1993, this area was
struck by a natural disaster that dramatically altered the landscape of the reserve and
its surroundings. The Malibu/Topanga Fire of November 1993 burned more than 17,000 acres
and destroyed more than 300 structures. At Stunt Ranch, most of the vegetation was burned
and all of the facilities were completely destroyed. Although this fire was set by an
arsonist, fire is a natural phenomenon that has long been a major factor in the ecology of
the Santa Monica Mountains.
The
reserve is now open and is again being used for research and education. While researchers
track the regrowth of vegetation on the charred slopes, facilities reconstruction and
University-community outreach are top priorities of the reserve's project and faculty
managers.
Stunt Ranch Santa Monica Mountains Reserve includes fine
examples of chaparral and oak woodland ecosystems. Its value is further enhanced by its
location adjacent to extensive natural areas, including state (State Department of Parks and Recreation) and
federal (Santa Monica Mountains National Recreation Area)
parklands and areas managed for conservation purposes by the Santa Monica Mountains Conservancy (SMMC) and the Mountains Restoration Trust (MRT). The
potential for cooperative research and education programs with these agencies is
tremendous. The reserve lends itself to programs that focus not only on the natural
ecosystems, but more broadly on issues of resource management in the urban/wildland
interface.
History (back to top)
Located in the heart of the
Stunt Ranch Santa Monica Mountains Reserve is a rich deposit of prehistoric artifacts
dating from 3,000 B.C. to 1,000 A.D. This is a significant archaeological site, offering
researchers and students an opportunity to study the changing adaptations of human
populations in the the Santa Monica Mountains. All of the major periods of regional
archaeological interest are represented here, providing a record that extends back to this
region's earliest human inhabitants.
Cold Creek Canyon's
eastern ridge marked the interface between two tribes of native Californians, the
Gabrielino and the Chumash. Although linguistically distinct, the two tribes were
culturally similar. Relations between them were generally friendly and intermarriage was
common. Gabrielino territory included Santa Catalina Island, a major source of steatite,*
which was highly valued for making tools and ornaments and was traded in rough or finished
form throughout California.
Spanish colonists settled
in the Topanga Canyon area in the late 1700s, but European settlement of the Cold Creek
watershed began with the arrival of the Stunt brothers. The Stunt brothers,
Harry, Walter, and Ernest and their cousin Sidney from Kensington, England,
homesteaded the Reserve land in the late 1800s, building a small cabin on the site around
1885. President Grover Cleveland approved the original homestead in 1889,
and Presidents William McKinley and Theodore Roosevelt approved additional
Stunt family homesteads in 1899 and 1904 respectively. The 300 sq. foot cabin,
believed to be the first building in the Cold Creek area was completely destroyed, as were
all other structures at Stunt Ranch, in the 1993 Malibu fire. The Stunt brothers planted a
large orchard, planning to establish a nursery to produce fruit-tree rootstocks. That
venture never worked out. In 1919, they built a larger cabin on the property. The Stunt
brothers lived and worked in Hollywood during the week, using the ranch on weekends.
Walter died in 1928, and Harry moved to the ranch in 1937. Their sister, Ethel, who had
spent many years as head secretary at the British Embassy in China, also moved to the
ranch in 1937. Harry and Ethel Stunt were both outgoing, friendly people who became well
known in the area for their hospitality.
In 1978, the State
of California purchased Stunt Ranch with park bond funds, and the Santa Monica Mountains
Conservancy assumed administrative responsibility for the site. Trails on the property
were opened for public hiking and equestrian use. The Cold Creek Docents, a division of
the Mountains Restoration Trust, expanded their environmental interpretation activities
onto the ranch from the adjacent Cold Creek Canyon Preserve.
In 1984, the University of California transferred
approximately 400 acres of land in the Santa Monica Mountains for public parkland as a
trade for the portion of Stunt Ranch that joined the UC Natural Reserve System in November
1995. The Stunt High Trail, which crosses through the western portion of the reserve,
remains open to the public daily from dawn to dusk for hiking and equestrian use.
*Steatite is a massive metamorphic rock,
greenish in color, that is closely related to soapstone and consists predominantly of
talc.
Natural Diversity of Stunt
Ranch (back
to top)
The Stunt Ranch Santa Monica Mountains Reserve lies within
the Cold Creek watershed, perhaps the best preserved and most biologically diverse
watershed area within the Santa Monica Mountains. Cold Creek itself, which flows through
the 243-acre section of Stunt Ranch adjacent to the reserve, has its origin on the north
face of 855-meter (2,805-foot) Saddle Peak, one of the highest points in the Santa Monica
Mountains. Cold Creek flows continuously throughout the year, even in dry years, although
the highly variable rainfall regime of coastal Southern California strongly affects the
level of flow. This permanent water flow, rare in the Santa Monica Mountains, is critical
for the maintenance of a number of rare species. Smaller tributaries of Cold Creek flow
out of the core area of Stunt Ranch Reserve, providing a well-developed corridor of
riparian habitat.
Rainfall records for the upper elevations of the Santa
Monica Mountains are not extensive, but it is estimated that Stunt Ranch receives a mean
annual rainfall of about 60 centimeters (23.4 inches). This average value, however,
obscures the extreme variability of rainfall between drought and flood years. In addition,
rain in this region may fall with remarkable intensity for brief periods.
Extreme summer temperatures may occasionally reach 111deg F
(40deg C) or higher. In general, however, temperature conditions are moderated by the
close proximity of the Pacific Ocean. Frosts occur occasionally in winter.
The core reserve area of Stunt Ranch encompasses a mosaic
of chaparral, live-oak woodland, riparian, and grassland communities. The chaparral
community on north-facing slopes is largely dominated by scrub oak (Quercus
berberidifolia), with a diverse mixture of other shrub species. Extensive areas of the
reserve are dry, south-facing slopes dominated by Ceanothus megacarpus, chamise (Adenostoma
fasciculatum), and laurel sumac (Malosma laurina). Adjacent areas of protected
lands support other chaparral communities with diverse shrub species, including redshank (Adenostoma
sparsifolium).
Coast live oak (Quercus agrifolia) is the primary
dominant of the oak woodland community. Riparian communities are particularly well
developed, both on small tributary streams and along Cold Creek. The dominant woody
species in the riparian zone are coast live oak, sycamore (Platanus racemosa),
California bay (Umbellularia california), and willows (Salix spp.).
Herbaceous riparian species include the relatively uncommon stream orchid (Epipactis
gigantea).

Ethel Stunt Oak Tree
The "matriarch" of the coast live oak woodland
community at Stunt Ranch is named for the matriarch of the Stunt Family, Ethel Stunt. It
is estimated that this majestic tree is between 500 to 1000 years old, was central to many
Chumash/Gabrielino ceremonies, and shaded the original Stunt homestead cabin. The Ethel
Stunt oak tree has also served as creative inspiration to the poets, artists, and
photographers who have visited Stunt Ranch. Some of her branches and part of her canopy
burned in the 93 Malibu fire, but the Ethel Stunt oak, like most of the oaks on the
Stunt Ranch Reserve, was not seriously damaged by the wildfire.
Both native and secondary grasslands are present on Stunt
Ranch. While European annual grasses are the dominant species in these areas, good local
populations of native bunchgrasses (Stipa spp.) occur as well. A rare member of the
sunflower family, Pentachaeta lyonii, a state-listed endangered species, is also
present. Overall, more than 300 species of vascular plants have been reported for the Cold
Creek watershed.
Vertebrate diversity is also high, providing almost a
complete cross-section of the vertebrate faunas of the Santa Monica Mountains. Bird
species are particularly abundant because of the mosaic of habitat types and the seasonal
presence of migratory species. The riparian corridors are especially rich, supporting
excellent populations of birds and amphibians. The Stunt Ranch fauna also includes the San
Diego horned lizard and San Diego Mountain kingsnake, both species of special concern to
the California Department of Fish and Game.
All of Stunt Ranch burned in the extensive Malibu/Topanga
Fire of November 1993. Chaparral and grassland communities burned to the ground in the
very hot fire, but shrubs are now resprouting from root crowns and seedlings of reseeding
chaparral specialists are becoming established. Oaks in the woodland community were
largely spared serious damage and have been resprouting new canopy leaves. Only in the
tributary riparian areas on the slopes of Stunt Ranch did the oaks receive extremely high
temperatures and extensive charring of their trunks. These oaks are now resprouting slowly
from epicormic shoots. The larger riparian areas along Cold Creek were spared the primary
fire intensity, because of their topographic position, and these have returned rapidly to
normal form.

Set in the southernmost mountains of the Transverse
Ranges, the Stunt Ranch Santa Monica Mountains Reserve
is located in the Cold Creek watershed of Malibu Creek,
perhaps the most pristine and biologically diverse watershed
in the Santa Monica Mountains. Cold Creek itself flows
year-round through the reserve. Smaller tributaries
of Cold Creek additionally provide the reserve with
a well-developed corridor of riparian habitat. Primary
habitats include chaparral, coast live oak woodland,
and annual grasslands. Overall, there are more than
300 vascular plant species, including the state-endangered
Pentachaeta lyonii, a rare member of the sunflower family.
The reserve also harbors an abundance of fauna, particularly
birds, and two rare reptile species: the San Diego horned
lizard and the San Diego Mountain kingsnake. All of
Stunt Ranch burned in 1993, but has recovered well.
The site’s natural diversity remains undiminished and
continues to provide excellent educational and research
opportunities. A quite well preserved early archaeological
site occupies the major central ridge of the reserve.
In the past, ancestors of the contemporary Chumash or
possibly the neighboring Gabrielino (Tongva) peoples
lived in this part of the Santa Monica Mountains and
used high ridges for collecting and processing acorns
and seeds, hunting, making stone tools, and many other
daily activities. Such locations may have been
seasonally used in one era and hosted long-term residential
occupation in others. The site's position on a
high, inland ridge and the dominance of older artifact
types seem to suggest that it may be at least 2000 years
old. The absolute dates of the site and the full range
of tasks carried out there are still being studied by
archaeologists. Later residents (AD 1800s) included
the Stunt family from Kensington, England who homesteaded
the property in 1885. Research is also possible at other
natural areas adjacent to the reserve under management
of the National Park Service, California Department
of Parks and Recreation, Mountains Restoration Trust,
and Santa Monica Mountains Conservancy.
