The most highly protected terrestrial areas around California’s Monterey Bay are designated as “Natural Preserves” by the California Department of Parks and Recreation and as “Ecological Reserves” by the California Department of Fish and Wildlife. Let’s explore where those places are, and how the State’s premier land management agencies are directed to protect areas with these designations.

CDFW Ecological Reserves

The California Department of Fish and Wildlife (CDFW) manages 1.1 million acres of land in California. Unfortunately, CDFW does not publish summary statistics about how many of those acres are designated as Ecological Reserves, which have the highest protection of any state-owned public lands, as reflected in the following regulatory language:

“….ecological reserves are maintained for the primary purpose of …..protection of rare, threatened, or endangered native plants, wildlife, aquatic organisms, and specialized terrestrial or aquatic habitat types. Visitor uses are dependent upon the provisions of applicable laws and upon a determination by the commission that opening an area to such visitor use is compatible with the purposes of the property.” (Cal. Code Regs. tit. 14 § 630Additional Visitor Use Regulations on Department Lands Designated as Ecological Reserves).

Note the stress on maintaining these properties for species and habitat conservation, first and foremost. And note that it takes a vote by the California Fish and Game Commission to allow any visitors to use those properties. Any such vote must be supported by an analysis of the impacts of such visitation on the species and/or habitats that the Ecological Reserve was designated to protect.

Local Ecological Reserves

The two CDFW Ecological Reserves that people regularly visit around the Monterey Bay are the Elkhorn Slough Ecological Reserve and the Bonny Doon Ecological Reserve. The two other CDFW Ecological Reserves do not allow public access without special permission: Quail Hollow and Watsonville Slough.

The Elkhorn Slough regularly has many visitors. The Fish and Game Commission appears to have at some point voted to approve visitor use at that property. However, a Commission-approved Elkhorn Ecological Reserve Management Plan outlining how visitor use is compatible with the conservation purposes of the property is not readily available. So, unfortunately, I can’t tell you what ‘conservation purposes’ were designated when the property was afforded such a high level of protection.

The other CDFW Ecological Reserve that the public visits was founded with the conservation purposes, according to their approved management plan, from 2003:

“The Bonny Doon Ecological Reserve (BDER) contains the largest and most pristine remaining occurrences of several rare plant communities which are limited to ancient marine sand deposits in Santa Cruz County. These communities contain three plant species which are considered to be rare or endangered: Santa Cruz cypress (Cupressus abramsiana) and Santa Cruz wallflower (Erysimum teretifolium), both listed as Federal and State endangered at the time of acquisition; and Ben Lomond spineflower (Chorizanthe pungens var. hartwegiana), which has subsequently been listed as Federal endangered….The BDER acquisition represented a unique opportunity to preserve a comparatively large area of rare habitat in nearly pristine condition”

In contravention to the regulation cited above, CDFW has allowed public use despite the Fish and Game Commission never having approved visitor use according a plan analyzing the compatibility of visitor use and protection of the Bonny Doon Ecological Reserve. Moreover, such a plan would also be required to have a Coastal Development Plan, approved by the California Coastal Commission. The 2003 management plan alludes to the need for a trail plan, but it is not clear if the plan’s environmental impact sufficiently addressed issues associated with the vague plans outlined in the document. The plan did, however, require creation of a monitoring program that designed to trigger changes in visitor use and trail maintenance. {ask for monitoring reports}

State Parks Natural Preserves

The California Department of Parks and Recreation manages 1.6 million acres of land. As with CDFW, Parks does not publish how many acres are designated as Natural Preserves. Natural Preserves have the highest protection of any State Parks managed lands, as reflected in the following policy language:

“… natural preserves will be established to give full protection to environmental and ecological integrity, from the standpoints of watershed influences, scenic and visual unity, cultural values, and other appropriate environmental factors.

Developments in natural preserves are limited to trails and interpretive facilities required to make possible the visual and sensory enjoyment of the resources by visitors. Vehicle access and parking are not appropriate; visitor centers, restrooms, structures, and facilities other than signs shall be placed outside natural preserves.

Bicycles are allowed only on paved roads in…Natural Preserves.”

Note the language, as with CDFW, stressing the primary importance of these State Parks areas for ecological conservation, and how Parks adds to this designation watershed processes and areas of cultural significance.

Local Natural Preserves

There are 5 Monterey Bay spots with State Parks Natural Preserve designation: Wilder Beach Natural Preserve (small, Wilder Ranch State Park); San Lorenzo Headwaters Natural Preserve (1800 acres, Castle Rock State Park); Theodore Hoover Natural Preserve (23 acres, Big Basin State Park); Año Nuevo Coast Natural Preserve (925 acres, Año Nuevo State Park), and; Point Lobos State Natural Preserve (550 acres). A large portion of the Año Nuevo Coast Natural Preserve has restricted public access and there is no public access allowed at Wilder Beach. The other spots allow public access, but, as noted in the above policies, no one is allowed to leave trails in areas with this designation, and bicycles are not permitted except on paved roads.

One Natural Preserve is missing from State Park’s list: the one that was to be designated for the coastal prairies in upper Wilder Ranch. During the process of approving use of that part of the park, Parks was discussing designation of vast areas of the diverse grasslands as a Natural Preserve. However, it turned out that Parks never updated the Wilder Ranch General Plan and so didn’t pursue such a designation, possibly due to opposition from mountain bikers.

How Are They Doing?

Many people reading this will be familiar with at least some of the areas listed above, places afforded the highest levels of conservation protection. For each spot, ask yourself: how are the managers doing? Do those areas seem to be better managed for conservation than other places? In the case of Wilder Beach, are snowy plovers nesting there…do people get away with trespassing there? In the case of the Bonny Doon Ecological Reserve, is visitor use truly compatible with protecting the many species and habitats, which includes the most endangered ecosystem in North America? How can we tell these stories and help the managers elevate these very special places to give them the protection they deserve?
