Summary:
Introduction:
The Sanctuary has one of the most diverse and abundant assemblages of
marine animals in the world, including six species of pinniped, thirty-three
species of cetacean, four species of sea turtles, ninety-four species
of seabirds and one
species of sea otter (fissiped).
The Sanctuary is
mandated to approach resource protection from a broad, ecosystem based
perspective. This requires consideration of a complex array of habitats,
species, and interconnected processes and their relationship to human
activities.
The Sanctuary provides
many opportunities for wildlife viewing, including whale watching, bird
watching, observation of pinniped pupping and haulout activities, and
tidepooling. With the multitude of opportunities for observing and interacting
with nature comes the potential for wildlife disturbance which may result
in impacts on marine resources such as: flushing of birds from nesting
sites, pinnipeds abandoning pups, potential harassment or even death to
wildlife. Certain recreational activities such as kayaking or scuba diving,
and some commercial activities such as low flying aircraft and fisheries
interactions have the potential to harm or disturb marine mammals and
seabirds.
Public awareness
is necessary to effectively address wildlife disturbance issues
since most people who choose to view marine wildlife do not intend to
place the
animals or themselves at risk. While it has been well established that
it is
harmful and dangerous to closely approach, handle or feed terrestrial
wildlife
(e.g., bears, deer, raccoons, nesting birds, etc.), many people do not
yet seem to
understand that these concerns also apply to marine wildlife.
Types of Wildlife
in the MBNMS
The MBNMS is known both nationally and internationally as a veritable
‘hot
spot’ for viewing marine life. There is significant interest and
public
participation in activities found in the region that offer wildlife viewing
accessibility. Following is a description of species present in the MBNMS.
Cetaceans:
Of the thirty-three species of cetaceans seen in the Monterey Bay area,
about onethird occur with frequency. Six of the whales are listed as endangered
species: the blue, fin, humpback, gray, right, and sperm. Other cetaceans
such as humpback whales, right whales, minke whales, fin whales, blue
whales and killer whales also seasonally inhabit the waters within the
MBNMS. The highest concentration areas of cetaceans are within the southern
and central portions of the MBNMS.
Pinnipeds:
There are a total of 9 rookeries/colonies in the MBNMS. The five species
of pinnipeds considered common in the Monterey Bay area include California
sea lions, Steller sea lions, Northern elephant seals, Northern fur seals,
and Pacific harbor seals. An additional species, the Guadeloupe fur seal,
has been reported from records of sick animals stranded on the beach.

Seabirds
and shorebirds:
Sanctuary waters are among the most heavily used by seabirds worldwide.
Ninety-four species of seabird are known to occur regularly within and
in the vicinity of the Sanctuary, and approximately ninety species of
tidal and wetland birds occur on the shores, marshes, and estuaries bordering
Sanctuary waters. Several environmental features are responsible for the
diverse assemblage of birds in the area, such as the Monterey Bay being
located on the Pacific Flyway, allowing the birds a place to stopover
during both north and south migrations between southern wintering grounds
and northern breeding sites. The upwelling of nutrient-rich waters adjacent
to the submarine canyon support
highly productive food webs which provide abundant seabird prey, as well
as
the diversity of habitat types along the shore which increases the variety
of bird
species which utilize the MBNMS.
Fissipeds:
The California or southern sea otter is a threatened species that is found
throughout the shallow waters of Monterey Bay from Pismo Beach to Año
Nuevo Island. Sea otters inhabit a narrow zone of coastal waters, normally
staying within one mile from shore. They forage in both rocky and soft-sediment
communities as well as in the kelp understory and canopy. They seldom
are found in open waters deeper than 30 m, preferring instead the kelp
beds, which serve as vital resting, foraging, and nursery sites. Otters
are an important part of the marine ecosystem. By foraging on kelp-eating
macroinvertebrates (especially sea urchins) sea otters can, in many instances,
influence the abundance and species composition of kelp assemblages and
animals within nearshore communities (Riedman, 1987).
Turtles:
The MBNMS is home to four species of sea turtles that frequent its waters
—the Green, Pacific Ridley, Leatherback and Loggerhead sea turtles.
The leatherback is the most common. It is the largest turtle in the world
and has the widest geographic range of any reptile. It is found in all
of the world’s major oceans and has been observed from the Artic
Circle to the edges of the Antarctic convergence zone. Leatherbacks are
also one of the deepest diving animals known—descending to depths
in excess of 1,300 meters. The leatherback is the world’s most endangered
sea turtle with populations in the Pacific Ocean declining at a disastrous
rate. Since 1980 populations have dropped by more than 90%, and the accidental
killing of leatherbacks by high seas commercial fishing fleets is a major
contributor to that decline.

Endangered
Species:
Of the more than 116 federally listed threatened or endangered species
(55 percent of all species nationwide) in California, twenty-six reside
within the Sanctuary. For
additional information on species found within the Sanctuary visit the
MBNMS site characterization at:

Potential
Disturbance Activities within the MBNMS:
Over the last twenty years, increasing numbers of people have been seeking
opportunities to view and experience marine wildlife. For the most part,
wildlife viewing has resulted in many positive benefits including new
economic opportunities for local communities and increased public awareness
and stewardship for marine resources. However, there is growing evidence
that marine wildlife can be disturbed and/or injured when viewing activities
are conducted inappropriately.
Frequent disturbance
has the potential to adversely effect marine species. The effects of disturbance
can be especially critical during sensitive time periods, such as feeding,
breeding, resting, or nesting. Disturbance is likely to cause avoidance
reactions and may result in interruptions of social behavior of animals
and is capable of leading to long-term changes in distribution.
Motorized
and Non-motorized Vessels:
The use of motorized or non-motorized vessels (outboard or inboard boats,
kayaks, canoes, underwater scooters, or other types of water craft) to
interact with marine mammals in the wild is a rapidly growing activity
nationwide. For example, NMFS and the MBNMS have received complaints from
members of the public that include operators of motor vessels driving
through groups of dolphins in order to elicit bow-riding behavior, whale
watching vessels getting too close to whales or chasing animals in order
to get a better view of them, and kayakers utilizing the quiet nature
of their vessels to approach too close to sea otters. All of these actions
cause animals to exhibit avoidance responses resultant from the interactions.
Fireworks:
Fireworks displays
over the Sanctuary have been traditionally conducted as part of national
and community celebrations and foster public use and enjoyment of the
marine environment. However, fireworks displays have the potential to
cause unacceptable levels of disturbance in certain areas. The MBNMS has
worked with the National Marine Fisheries Service and the US Fish and
Wildlife Service in developing solutions to this issue; it is expected
that final implementation of those guidelines will occur in 2003. Traditional
community fireworks displays will be allowed to continue at the existing
locations, but there will be constraints on the number allowed per year,
as well as designated zones
where fireworks will be prohibited.
Overflight
Impacts:
Potential impacts from low-flying aircraft are addressed by a specific
prohibition on flying under 1000 feet in designated overflight zones with
sensitive wildlife. Some implementation problems have occurred due to
pilot’s lack of understanding and acknowledgement of the zones since
they are not noted on aeronautical charts. MBNMS has begun an outreach
campaign to pilot associations on the zones and the impacts of low flights,
and is working to include notations on the FAA aeronautical charts. Additional
outreach may be required to reach aviation companies which may be conducting
whale watching trips within the Sanctuary Overflight Restriction Zones,
as this activity is also know to cause animals to exhibit avoidance responses
resultant from the interactions.

How does
the MBNMS currently address Wildlife Disturbance?
MBNMS addresses wildlife disturbance through a mix of educational outreach,
regulations and enforcement. Sanctuary regulations explicitly prohibit
harassment of marine mammals (as defined under the Marine MammalProtection
Act), sea turtles and birds. Other Sanctuary regulations relating to wildlife
disturbance include restrictions on flying motorized aircraft below 1,000
feet in three designated sensitive areas, a prohibition on attracting
white sharks, and restrictions on the use motorized personal watercraft.
Non-regulatory measures are also used by the Sanctuary to address wildlife
disturbance, and include a variety of education and outreach activities
and products.
There are several
docent programs in high visitor use areas in the MBNMS. Some programs
have been enacted to address concerns at specific locations such as the
State or County Parks Programs at Point Lobos and the Fitzgerald Marine
Reserve, other docent programs are more regional. Below is a description
of MBNMS programs which enlist the help of specifically trained and educated
volunteers.
Team
OCEAN:
An effort to address the disturbance of marine mammals and seabirds by
recreational users of the Sanctuary was launched by the Sanctuary during
the fall of 2000, and is now in its 3rd year. The Team OCEAN summer outreach
program employs on-the-water education efforts on the Monterey Peninsula
and in Elkhorn Slough to prevent kayakers from approaching marine mammals
such as sea otters too closely. Similarly, the Sanctuary has assisted
in reducing harassment of the elephant seal population at Piedras Blancas,
a location very near the highway where tourists were closely approaching
the animals. These efforts have included assisting local nonprofit organizations
in establishing an observer and docent network for the elephant seal haulout
sites to facilitate observation opportunities at safe distances and locations,
and improving interagency enforcement for cases where an educational approach
has not sufficed.
Beach
COMBERS:
In 1997 a volunteer beach-monitoring program (Beach COMBERS: Coastal Ocean
Mammal/Bird Education and Research Surveys) was established by the MBNMS
and Moss Landing Marine Labs, to obtain information on rates of stranding
for all Sanctuary marine birds and mammals. In addition, mortality events
are detected, causes of mortality events are assessed, and oil and tar
deposition is monitored. Some success stories to date include the discovery
of banded birds from as far away as Hawaii; detection of unusually high
numbers of dead adult harbor seals in localized areas; and a high deposition
of Common Murres (a diving seabird), which led to the discovery of a previously
unrecognized threat of gillnet mortality for Common Murres, harbor porpoise,
and sea otters. The Beach COMBERS program has recently been expanded to
Cambria, in the southern Sanctuary region. This program can help detect
wildlife mortality patterns, although there often are a variety of possible
causes of death.

Friends
of the Elephant Seal:
The Friends of the Elephant Seal (FES) is a non-profit organization, formed
in 1997. It is dedicated to educating people about elephant seals and
other marine life and to teaching stewardship for the central coast of
California. The organization puts volunteers through a comprehensive training
program, using local experts. Volunteers work at the elephant seal viewing
site year-round, 7 days a week, from 10 - 4. Docents make over 150,000
contacts per year, with visitors coming from all over the world. The program
redirects visitors to appropriate viewing sites and advises visitors of
safe viewing practices. MBNMS has provided funding for signage at the
main viewing site, and serves as an advisory member to the Board of Directors,
participates in the docent trainings, and provides general assistance
and support.
BAYNET:
BAYNET, an all volunteer, non-profit organization founded in 1996, is
dedicate to the protection of natural resources and educating people about
the wonders of the ocean and the living marine resources in California's
Monterey Bay region. During the program's first four years, BAYNET volunteers
spoke with more than 200,000 visitors from all over the world. In the
year 2000 alone, BAYNET volunteers donated 1,700 hours of service. The
MBNMS provides staff assistance and partial funding for the program.
Watchable
Wildlife:
The Watchable Wildlife program is a unique partnership of federal and
state wildlife agencies and non-profit organizations working to educate
the public and commercial operators about safe and responsible wildlife
viewing practices. The program has three immediate goals: (1) enhance
public wildlife viewing
opportunities; (2) provide education about wildlife and its needs; and
(3) promote active support of wildlife conservation. Within NOAA, the
National Ocean Service (through the National Marine Sanctuary Program)
and the National Marine Fisheries Service (through the Office of Protected
Resources) have been working together with the Watchable Wildlife program
partners over the past five years to develop a “Watchable Wildlife”
program specifically for marine species and habitats. The main purpose
of the program is to provide the public with information about appropriate
wildlife viewing practices for the marine environment that are consistent
with wildlife protection laws and conservation efforts.
Regulations:
Harassment within the Sanctuary is governed by a complex array of multijurisdictional
laws and regulations such as the National Marine Sanctuaries Act, the
Endangered Species Act, the Migratory Bird Treaty Act, and the Marine
Mammal Protection Act. The following activities are prohibited within
the Sanctuary: exploring for, developing or producing oil gas or mineral,
discharging materials (with certain exceptions), altering the seabed,
disturbing marine mammals sea turtles and birds, attracting white sharks,
moving removing or injuring a Sanctuary historical resource, possessing
any historical resource, marine mammal, sea turtle or seabird, and flying
motorized aircraft below 1,000 feet in certain areas.
(top)
Enforcement:
The shoreline of the MBNMS is approximately 300 miles long. The MBNMS
has one dedicated NOAA Office of Law Enforcement agent to respond to potential
violations of Sanctuary regulations. The Sanctuary relies heavily on collaborations
with other cross-deputized partners such as the Department of Fish and
Game and State Parks to assist with Sanctuary enforcement. As might be
expected with one dedicated agent responsible for coverage of an area
the size of Connecticut, this enforcement agent has limited capabilities.
The MBNMS also funds a half-time law enforcement officer working in the
Cambria area, who assists with enforcement issues during the elephant
seal pupping season and collaborates with the Friends of the Elephant
Seal docents. The MBNMS currently addresses some of these harassment issues
through regulatory measures such as prohibitions of white shark attraction
and marine mammal and seabird harassment, and over-flight restrictions
for sensitive areas; as well as non-regulatory measures and other education
and outreach efforts to minimize impacts to living marine resources. However,
major disturbances to marine mammals and seabirds continue to be a major
issue within the MBNMS and will be addressed in this Management Plan Review.
A framework and strategies to address this issue will be incorporated
and implemented as part of this site-specific action plan.
Strategies
to be pursued in the Work Group:
Despite the initial efforts outlined above, many species in the Sanctuary
warrant further protection via outreach, education, enforcement or other
strategies designed to inform the public and specific user groups of the
need to prevent wildlife disturbance within the MBNMS. The goal of this
working group is to develop a framework of protective measures for human
interactions with marine mammals, seabirds,and turtles through wildlife
viewing and aircraft overflights in the Sanctuary. The initial phase will
focus on identifying gaps in the existing system of protection and formulating
a plan to jointly develop specific, more detailed, recommendations for
those topics which have emerged as priorities.
Product
expected:
This working group will consist of one main group that meets regularly
however some participants or sub-groups will be given assignments for
some of the specific details and issues, and will report back to the main
group. This workgroup will be responsible for developing a framework in
which to address these issues over the next few years. Categories of strategies
will likely include targeted and focused education and outreach, improved
enforcement, disturbance guidelines, and survey and monitoring activities.
The following
issues are known to be of concern within the MBNMS:
•
Whale watching harassment
• Marine debris
• Kayak disturbances (harbor seals, sea otters, seabirds, and sea
lions)
• Elephant seal harassment
