History and culture

People: 5

The Santa Monica Mountains lie between Malibu and El Camino Real (the royal highway) or as we now know it: the 101 freeway. Before the strip malls, city lights, and beachfront property the mountains and inland areas were home to the Chumash and Tongva Native American groups . They lived here for thousands of years.

Later it was home to Spaniard ranchers who settled the land on behalf of the king of Spain who feared Alta (upper) California would be colonized by Russia and England.

After that a multi-ethnic group of homesteaders forged their way through the rough canyons when President Lincoln passed the Homestead Act of 1862. These settlers brought new foods, new ideas, and new cultures to the area that has shaped the California landscape and mindset.

The mountains and inland areas have affected and been affected by the people that lived here in the past.

Native American Indians: 6

Native American Indians have lived in the Santa Monica Mountains and surrounding area for over 10,000 years. Though of different languages and tribes, they lived a similar lifestyle based on the abundant food and materials provided by the environment. They fished in the ocean, hunted rabbits and deer in the canyons, and gathered acorns from the oak woodlands. Prosperous and industrious, the tribes who inhabited the mountains lived in the center of a network of commerce that extended up and down the coast, west to the Channel Islands, and inland to Arizona. Today we know the descendants of these people as the Chumash in the western and the Tongva in the eastern portions of the mountains. We are in the process of expanding this section. For more information on the Chumash, please visit the Satwiwa Native American Indian Culture Center in Newbury Park. There you can learn about Chumash culture and walk inside a replica of an 'ap, a Chumash house.

Ranchos & Ranchers: 7

In the 1700s Spain feared England and Russia would colonize Alta (upper) California, so they made an effort to establish a permanent settlement first.

In order to protect its interest in North America and to continue the chain of missions started in Baja California, King Carlos III of Spain set up the Sacred Expedition. The idea was to turn the Native Americans into civilized gente de razon (people of reason) and to take advantage of the labor they could provide in building missions and tending the land. The mission period lasted over 50 years. They were set up as self-sustaining mini-cities that could provide food and supplies for everyone who lived in the mission as well as the presidios and nearby pueblos. The padres choosing the mission sites found the best lands for cattle and sheep grazing; growing crops like wheat and vegetables; planting fruit orchards, and vineyards. This valuable land was envied by settlers who did not belong to the Spaniard military and was a major cause for the Mexican Independence Revolution and the Secularization Act.

Ranchos were large sections of land used to raise cattle and sheep and in the beginning were not available for purchase because the land, roads, and trails belonged to the King of Spain. The king let Spanish soldiers and Mexican settlers "borrow" the land so that foreigners would be discouraged from trying to make their own colonies. At first many people had to be persuaded to move to Alta (upper) California because it was so desolate. The king offered retiring soldiers 2,000 head of cattle and free supplies for the first two years if they would leave the comfort of their homes in Mexico and take up permanent residence in Alta California. Residents of Mexico including African Americans and Indians were also allowed to go to Alta California to live near the pueblos.

The first land grants for ranchos were given during the mission period, but after the missions closed down many more ranchos were established throughout California and the landscape changed forever. The Spaniard rancheros (ranchers) brought sheep, cattle, horses, wheat, and other foods not found in California or America. Think of how different the dinner table might be without some of these staples we know and love.

Present day Topanga, Agoura Hills, Malibu, Thousand Oaks, Westlake Village, and many other areas of southern California were once cherished for their wild grass and fresh water areas that sustained the livestock.

Homesteaders: 8

On May 20, 1862 President Abraham Lincoln passed the Homestead Act. This law allowed any U.S. citizen, or future citizen, to apply for and lay claim to 160 acres of surveyed government land. First, they had to file an application, pay a small fee, improve the land, and file for the deed of title. In the first five years, the homesteader had to live on the land and make improvements by building a 12 by 14 dwelling and by growing crops. When the five years was up they had to show proof of the improvements and could then file for the land patent (now called deed of title).

This act brought more Mexicans to the Santa Monica Mountain area. Many families had already moved to the area when travelers brought news back to Mexico of how well the Missions and their cattle were doing due to the large pasture areas, fresh drinking water, and fertile soil. Spaniard colonists had been struggling to raise their cattle on the rocky landscape of Mexico, which brought the initial wave of people to the Santa Monica Mountains area. It also brought many other people from various cultural backgrounds and provided a polyglot mixture of homesteaders during this time.

Since 1771 California had belonged to Spain and then in 1822 Mexico overthrew their Spaniard control and California became property of Mexico. In 1848 California became part of the United States with the signing of the Treaty of Guadalupe Hidalgo. Although many of the Mexican homesteaders and rancho owners moved away from their lands into other parts of California or the United States, they left behind a strong cultural heritage that can be seen from San Diego to San Francisco.

History & Culture: 9

The landscape of the Santa Monica Mountains was not just created by geological forces, altered by weather, or covered by vegetation, but shaped by the people who lived and worked here.

People came to this area for many reasons. Initially, the Chumash and Tongva called the Santa Monica Mountains home. Then Spanish Explorers passed through these lands, followed by Rancheros and Homesteaders who worked the land they lived on. Still today, people work, travel, and recreate in the Santa Monica Mountains and call this place their home.

There are places that still remain from our past. Places we can touch and feel. Paramount Ranch , Solstice Canyon , and Rancho Sierra Vista / Satwiwa . All places that you can visit. Places that most importantly, create an emotional and intellectual connection to our past.

As a park, we look deep into the past through archeology and historical research. Investigating what people left behind. Into their past and the collections that tell the day to day story of their lives. From photographs to letters to even the things they threw away; everything tells a part of the story we share.

Santa Monica Mountains National Recreation Area strives to ensure the preservation of these collections, places, and stories of the people who impacted the landscape forever.

Nature

Ecology; Nature & Science: 10

Located adjacent to the city of Los Angeles, the second largest urban area in the United States, Santa Monica Mountains National Recreation Area protects one of the largest and most significant examples of Mediterranean-type ecosystems in the world. The climate of the Mediterranean ecosystem, characterized by wet winters and warm, dry summers, along with the diverse topography in the Santa Monica Mountains has created a landscape filled with unique natural resources.

The Santa Monica Mountains are part of the east-west trending Transverse Ranges of Southern California. The range is geologically complex and characterized by steep, rugged mountain slopes and canyons. Elevations range from sea level to more than 3,000 feet. The Santa Monica Mountains are adjacent to 46 miles of scenic California coastline with sandy beaches and rocky tide pools and lagoons.

There is tremendous ecological diversity within the Santa Monica Mountains. The mountains are home to over 1,000 plant species making up 26 distinct natural communities, from freshwater aquatic habitats and two of the last salt marshes on the Pacific Coast, to oak woodlands , valley oak savannas , coastal sage , and chaparral . Numerous mammals are found in the Santa Monica Mountains, including bobcats , coyotes , and mountain lions . Nearly 400 species of birds have been observed and another 35 species of reptiles and amphibians can also be found in the mountains. The Santa Monica Mountains are home to more than 50 threatened or endangered plants and animals - among the highest concentrations of such rare species in the United States.

Birds: 11

From oak woodlands to grassland savannas to the coastal shore, the many diverse habitats of the Santa Monica Mountains support a wide variety of resident and migrating birds. More than 380 species - nearly half the North American total - can be seen year-round including shorebirds, songbirds, woodpeckers, and raptors. At Malibu Lagoon alone, more than 250 species have been recorded. Of all the species found in the recreation area, about one-third reside and breed here.

Migration is an especially amazing time, when literally millions of birds pass through or settle in for the season. Large populations come and go, following the food sources that suit their breed along the Pacific Flyway. The region's Mediterranean weather make the mountains and coastline the perfect place for seasonal stopovers. Birders (or birdwatchers) also flock to the Santa Monica Mountains in search of our many specialties and vagrants.

Plants: 12

The Santa Monica Mountains are home to 12 vegetation communities, which are derived from 26 vegetation associations identified by the California Natural Diversity Database classification system (Holland 1986). These include coastal salt marsh , coastal strand , coastal sage scrub , chaparral , coast live oak woodland , riparian woodland , valley grassland , valley oak savanna , freshwater ponds/lakes, rock outcrops, and suburban development.

Vegetation communities are determined by the following factors: presence of water, elevation, aspect, soil, proximity to the ocean, and presence or frequency of fire.

However, a battle to protect this ecosystem from invasive plants is being waged in the mountains. Noxious invasives commonly called weeds are still spreading through out the Santa Monica Mountains. Early detection is key in preventing large ecosystem impact.

Natural Features & Ecosystems: 13

The Santa Monica Mountains rise above Los Angeles, widen to meet the curve of Santa Monica bay, and reach their highest peaks facing the open ocean. The land is beautiful and diverse. The rugged coastline offers narrow sandy beaches and rocky shores. Dense chaparral and fragrant sages cover the canyon walls. Inland, lone valley oaks accentuate the grassy hillsides.

Born from the collision and sliding of the Earth's crustal plates, the mountains are home to some of the most unique and rare natural features and ecosystems in the United States.

Part of the Transverse Ranges that stretch from the Mojave Desert to the Channel Islands, these mountains are some 46 miles long and eight miles wide. Volcanic Sandstone Peak, at 3,111 feet above sea level is the highest point in the park!

Explore the pages above and learn how an area home to millions of people and visited by millions more makes this shining star of Southern California so special.

Coastal Sage Scrub: 14

In the Santa Monica Mountains, coastal sage scrub occurs on drier sites and lower elevations than chaparral, especially on coastal south-facing slopes. Coastal sage scrub is also common in inland areas of the Simi Hills within the park boundary. Often occurring in recently eroded areas, this community plays an important role in soil stabilization. Many of its characteristic plants produce soil-holding, fiberous shallow roots. Soils underlying coastal sage scrub tend to be low in nutrients and subject to rapid erosion.

The coastal sage scrub community has been referred to "chaparral" since soft-leaved, grayish green, aromatic shrubs characterize the widely spaced vegetation. Characteristic plants include purple sage ( Salvia leucophylla ), California sagebrush ( Artemesia californica ), coast goldenbush ( Haplopappus venetus ), coastal buckwheat (Eriogonum cinereum ), laurel sumac ( Malosma laurina ), and lemonadebery ( Rhus integrifolia ).

Many species in this community, particularly the sages, are summer or drought deciduous, dropping larger leaves during mid-summer to conserve moisture.

Good examples of coastal sage scrub can be found at the mouth of Zuma Canyon and in coastal Point Mugu State Park.

Animals: 15

The Santa Monica Mountains support an abundant and diverse wildlife community, which is reflective of the diversity of the vegetative communities encompassed within the park boundary. More than 450 vertebrate species occur in the park. The relatively intact wildlife populations of the mountains are especially impressive considering their proximity to one of the largest urban areas in the United States. The continued maintenance of wildlife populations in the Santa Monica Mountains is dependent on the ability of public and private land managers to ensure adequate habitat for the most sensitive species. Learn about our amphibians , birds , fish , mammals , and reptiles .

Mammals: 16

Over 45 mammal species can be found in the Santa Monica Mountains, and they range in size from shrews, which weigh less than one ounce, to mountain lions weighing up to 150lbs. However most of these are smaller mammals such as squirrels, gophers, mice, rats, rabbits, and insectivores such as bats , shrews, and moles. Although some of these small mammal species are considered pests by some people, they are actually an important part of the natural ecosystem. They eat insects, till soil, and disperse seeds. They are also a food source for many other inhabitants of the Santa Monica Mountains including mammalian carnivores, reptiles , and raptors (birds of prey).

Mammals, like other animals, generally occupy a defined area of habitat, termed a home range, where they will acquire food, find shelter, and locate mates. Territorial animals such as some carnivores will defend their home range, or at least part of it, and attempt to exclude other members of the same species and sex.

As urban development continues within and around the Santa Monica Mountains, fragmentation of the natural habitat poses one of the greatest threats to mammals. It makes it harder for them to find suitable home ranges, and it creates barriers between populations and individuals.

Biologists at Santa Monica Mountains NRA have been working to understand how some animals interact with and are affected by urbanization and fragmentation. We have studied small mammal abundance and diversity in habitat fragments of varying sizes, as well as their exposure to toxicants in urban areas. We have also worked in conjunction with Caltrans to study the effects of local freeways on some animals, particularly larger mammals. Freeways such as 101, 405, and 23 can be a barrier to movement and a source of mortality for many species.

Since 1996 the National Park Service has been studying mammalian carnivores in and around the Santa Monica Mountains and Simi Hills. We have studied mountain lions , bobcats , gray foxes, mule deer and coyotes using radio and GPS telemetry collars, remote cameras, and scat (animal feces) surveys. During this time we have captured and ear tagged or collared over 290 bobcats, 130 coyotes, 29 gray foxes, and 22 mountain lions. The goals of these studies are to look at the affects of urbanization and habitat fragmentation on the distribution, abundance, behavior, and survival of these species. Urbanization can impose many new obstacles and challenges on wildlife, especially for animals with large food and space requirements such as mammalian carnivores. Specifically we have looked at issues such as habitat loss, movement barriers such as roadways and high density urban development, and sources of mortality.

Hola, my name is Jazmín Ortega and I live in the Boyle Heights neighborhood of Los Angeles. Although I've lived here many years, I didn't know about the Santa Monica Mountains National Recreation Area until I hiked to Sandstone Peak about 10 years ago. All this national park land all around me and I didn't even know about it. Wouldn't it be great if more people experienced the outdoors? In 2017 I saw a post by Latino Outdoors, inviting us to hike the Backbone Trail, the premier hiking trail in the Santa Monica Mountains. I was thrilled to be selected to be part of this group that hiked eight segments of the backbone trail with park rangers and volunteers. If you're interested in hiking the Backbone Trail, I highly recommend it, but being prepared is key. That's why the National Park Service is coming out with a series of videos for folks interested in hiking a segment of the trail or all 67 miles of it from Point Mugu to Will Rogers State Historic Park. The series will cover logistical issues and what to bring, and break down the eight segments of the trail that you can follow, along with valuable insights from park rangers on natural and cultural resources along the way. I hope you can check it out, see you on the trails.
