Guadalupe-Nipomo Dunes is the largest remaining
The Guadalupe-Nipomo Dunes Complex is home to a unique dunes ecosystem as well as many endangered and threatened species of plants and animals. To protect the dunes environment, much of the Complex has been set aside for conservation. In addition, it is recognized as a National Natural Landmark.[3]
Another portion of the Dunes is utilized for recreation, such as camping and
History
The first known inhabitants of the Guadalupe-Nipomo Dunes were Native Americans of the
Film
In 1923, the epic movie The Ten Commandments directed by Cecil B. DeMille, was filmed on the Dunes. At the end of production, the massive sets reproducing ancient Egypt were dismantled and buried on the site to prevent reuse.[7] The location was later used to film the episode "White Tip's Journey" (set in Late Cretaceous Mongolia) of the dinosaur documentary miniseries Dinosaur Planet in 2004. As of 2013[update] they remain buried there, despite decades of various proposals for excavation.[8] Some artifacts have been recovered and are on display at The Dunes Visitor Center, while others may be seen from time to time as the dunes shift.[9][10][11] Portions of Beyoncé's Black Is King were filmed on the Dunes in 2019.
Dunites and oil
From the 1920s until the 1940s, a group of mystics, nudists, artists, writers, and hermits known as the "Dunites" inhabited the Dunes.
Conservation
Starting in the 1970s, measures were taken to protect the natural environment at the Dunes. One of the biggest changes was the restriction of
Geography and environment
The Guadalupe-Nipomo Dunes were formed by a combination of factors including beach sand which was blown inland by the wind and the Santa Maria River which brought sediment to the coast. Dune-building began 18,000 years ago with the Nipomo and Orcutt Mesas.
Even though the Guadalupe-Nipomo Dunes consist of moving sand with extremely low moisture that is seemingly deprived of nutrients, it is home to a variety of
The dunes are separated into uplands and wetlands habitats. Uplands include the fore dunes, back dunes, and sandy beaches. Dunes can occur in three different formations. Primary Foredunes are parallel to the shore and support sparse vegetation. Parabolic dunes are U-shaped and perpendicular to the shore with vegetative ridges. Moving sand sheets consist of constantly moving sand, making it hard for vegetation to settle. The fore dunes begin at the high tide line, where only low growing plants with deep root systems (such as
Weeds have been introduced into the Dunes environment both purposefully and accidentally and threaten the native plant life. Various native plants are being choked out by invasive species like European beach grass.[21] European beach grass achieves higher cover than native dune grass and is stimulated to grow by sand burial, causing a positive feedback.
Many species of animals can be found among the dunes. Over 200 species of birds live there, such as the
Dust and air quality
The dunes have been involved with an ongoing series of environmental debates regarding the reduced air quality found in the receiving towns downwind of the dune system. Physical effects by the dust aerosols are indicated by accounts of homeowners claiming discomfort in breathing during times of high dust concentration,
Western snowy plover
Off-road vehicle use partially conflicts with habitat of the western snowy plover (Charadrius nivosus) which was listed as threatened under the
Ecologists argue that the snowy plover does not just breed on any coastal area; they seek protection in the dunes.[28] Scientist Tom Jordan studied data on bird nesting sites and found that snowy plovers "prefer the beach and the flatter areas," such as on top of the dunes, where they can watch for predators.[29] Plovers prefer nesting on open sand which can put nests at risk of being crushed by vehicles or hikers.[30]
The Santa Lucia Chapter of the Sierra Club proposed year-round fencing to protect plover habitat, but the Oceano Dunes State Vehicular Recreation Area rejected the idea.[31] Soon after the decision, a plover was killed by an off-road vehicle in a recommended area for fencing. The Sierra Club sued the State Parks for violating the ESA by not providing enough protection for the snowy plover, as well as the California least tern and steelhead trout.

Management, uses, and ownership
Within the Guadalupe-Nipomo Dunes Complex are several distinct regions, each managed by different organizations and used for various purposes.
- Pismo State Beach
- North Beach Campgrounds is located at the northernmost part of the Dunes and is run by the California Department of Parks and Recreation.[32]
- Oceano Campgrounds is located further south than the North Beach Campgrounds, near the town of Oceano. The Oceano Campgrounds, like the North Beach Campgrounds, is run by the California Department of Parks and Recreation and also has a nature museum on site.[32]
- The Oso Flaco Lake Natural Area is part of the Oceano Dunes State Vehicular Recreation Area located north of the city of Guadalupe. Visitors to the Natural Area can walk along the mile-long boardwalk that follows the creek, passing across Oso Flaco Lake, to the ocean.[33]
- The California Office of Environmental Health Hazard Assessment has issued a safe eating advisory for any fish caught in Oso Flaco Lake due to elevated levels of DDTs, dieldrin, or mercury.[34]
- The Dunes Center is an agency developed to promote the conservation of the Dunes ecosystem through education, research and cooperative stewardship. It receives funding from both private and public sources. The Dunes Center is located in the city of Guadalupe, in a restored 1910 craftsman bungalow.[35] The Center features exhibits about the natural history of the dunes, and the area's cultural history.[36]
- The 2,553 acres (1,033 ha) giant coreopsis, California red-legged frog, western snowy plover, and California least tern. Access is seasonal and requires a long hike. Dogs and pack animals are prohibited.[37]
- Rancho Guadalupe Dunes County Park is located at the southern end of the dunes and is owned by the Santa Barbara County Parks and leased to the Center for Natural Lands Management. In comparison to other areas of the Dunes, Rancho Guadalupe Dunes County Park is the least damaged by introduced invasive plant species. For visitors, the Park offers bird and whale watching, fishing, hiking areas, picnic area (no BBQs/cooking permitted), interpretive kiosk and trailer. Seasonal restrictions during the nesting bird season (Mar 1 - Oct 1) apply and are posted on site.[38]
- Oceano Dunes State Vehicular Recreation Area (SVRA) is located south of 2019 COVID-19 outbreak, a study by a Cal Poly San Luis Obispo professor found that there was no significant impact on the county's economy. He analyzed tax and unemployment data collected from March through August 2020. However, in contrast, a 2017 study commissioned by State Parks found that revenue generated by the OHV visitors resulted in $243 million for the county,... a survey in which participants said that they would not visit if the vehicular recreation area did not exist. The professor wrote in his study concerning the possibility of less visitors, "While this may be the case for the OHV visitors, it is certainly not the case for the pedestrian and equestrian visitors."[43]
The Oceano State Vehicular Recreation Area has taken measures to protect wildlife by fencing off specific areas from pedestrians and vehicles and creating rules for visitors. Some rules are: adhere to the 15 mph (24 km/h) speed limit, do not enter closed areas, keep dogs on a leash at all times, and rid the beach of trash that could attract predators.[44] During the busy holidays, extra rangers are brought into the park to ensure rules are enforced.
Ownership
For 25 years, the County of
The State Parks offered to pay $4.86 million for nearly 584 acres (2.36 km2) of beachfront property that is directly in the middle of the Oceano Dunes State Vehicular Recreation area. Various groups and individuals would like to see the land sold to the State Parks. Currently, the Oceano Dunes State Vehicular Recreation Area uses one third of the beach territory for off-road vehicles use. Off-roaders are concerned that since the decision is in the hands of the county, San Luis Obispo County's environmental community may advise more restrictions on the land if it isn't sold. Land available for vehicle use has already been reduced from 15,000 acres (61 km2) to 1,500 acres (6.1 km2). The State wants to buy the land in order to secure a place for off-road vehicles for the future. They claim not all the land would be used for off-road vehicles and camping, and that part of the land would be set aside as preserve areas, as the County wants. On Tuesday April 17, 2007, the San Luis Obispo Board of Supervisors voted 4-0 not to sell the 584 acres (2.36 km2) of land to the State.
