July 2004 — There she was again one day last winter, lying on the beach at
Ho‘okipa, catching some rays and some well-earned sleep. She
probably had been up all night, rousting the reef and rubble,
gorging herself on lobster, octopus and eels. Occasionally, she’d
open one large, liquid eye to check her surroundings before
slipping back into her fin-footed dreams.
I couldn’t help wondering if “Makana,” a Hawaiian monk seal, was
resting so peacefully because she knew that we members of the
Monk
Seal Watch Team were keeping an eye on her. I have watched over Makana for the last eight years, mostly at Ho‘okipa. A number of
times, like that day last summer, I have helped put up a barrier of
yellow plastic tape around her on three sides to keep people at a
safe distance. This is her “seal safety zone,” a buffer to protect
both the seal and beachgoers, while still allowing her access to
the water.
The safety zone should really be a good 150 feet in diameter,
according to National Marine Fisheries Service (NMFS) guidelines,
but our little beach at Ho‘okipa is just too small for that.
Fortunately, Makana is more tolerant of human company than most of
her relatives. This has allowed her to adapt to a smaller safety
zone, giving windsurfers and others access to this very popular
spot. In fact, I’ve seen Makana snooze through a couple of
windsurfing contests, with surfers launching all around her.
But there is a fine line between tolerance and dangerous
habituation, the type that can be dangerous for both humans and
animals. Brad Ryon, with the National Oceanic and Atmospheric
Administration (NOAA) Fisheries, is working hard to foster a
“culture of co-existence” between seals and humans, one in which a
stewardship ethic flourishes for all marine resources.
A seal slumbering on the sand can look like a cross between a beach
rock and a stuffed animal, so it’s no wonder that people don’t
always notice them. But once they do, they are sometimes tempted to
rush over and pet or hug or pour water on them. That would be a big
mistake, since 600 pounds of surprised monk seal with inch-long
canines can move alarmingly fast. And seals don’t need us treating
them like pets.
Ryon cautions that monk seals should not get so habituated that
they become beggars like some of the bears in Yellowstone National
Park. During a terrifying ocean encounter with an amorous male monk
seal, he experienced first-hand just how powerful these animals
are. The main thing we need to do when we encounter them, Ryon
says, is, “give ’em their space, and give ’em a chance.”
Makana, named by the Ho‘okipa community to acknowledge her presence
as a gift, is one of 50 to 150 endangered monk seals estimated to
make the main Hawaiian Islands their home. The majority of the monk
seal population, more than 1,200 animals, is found among the
Northwestern Hawaiian Islands beyond Kaua‘i. And Makana’s presence
here truly is a gift — a bright ray of hope in the otherwise cloudy
future of the Hawaiian monk seal.
There are six major breeding sites in the northwest chain’s atolls
and increasingly births are occurring in the main Hawaiian Islands
too. In 1994,
Bill Gilmartin, then leader of the Hawaiian Monk Seal
Recovery Program for the NMFS, headed up an effort to relocate 21
males from Laysan Island in the northwest chain to the main
islands. An over-population of males at Laysan was leading to
aggressive behavior. These extra guys were dropped off in the
waters ranging from the north shore of Kaua‘i to the southern tip
of the Big Island.
Although it’s not known for sure if these males bred with the
females found here, since the relocation there has been an
increasing trend in pup births in the main islands. Gilmartin, as
proud as a new uncle, thinks that’s good news, since it appears
that there is a recent trend for pups born in the northwestern
islands not to make it past their first year of life.
Unfortunately, despite more than 20 year’s worth of efforts by the
NMFS to recover this species, and even though births are increasing
in the main islands, the Hawaiian monk seal population overall has
declined at an average rate of 3 percent per year since 1985. It’s
likely the decline would have been even more precipitous, if not
for all the efforts of the NMFS and numerous volunteers.
Hawaiian monk seals reflect the health of the marine ecosystem.
Sometimes referred to as an “indicator species” (like the
proverbial canaries in a coal mine), the precarious status of these
shy creatures tells us that our near-shore waters are indeed
troubled.
One of the main threats to the recovery of these seals is the
somewhat perplexing loss of juveniles in the Northwestern Hawaiian
Islands. Pups are born, but many are just not making it
to the ripe
old age of 4 or 5, when they reach sexual maturity. The reasons why
include predation by sharks, entanglement in webs of marine debris,
competition for prey with other apex predators like jacks and
sharks, attacks from older male seals — who have been observed
killing young of both sexes as they attempt to breed with them — and
a general reduction of the seal’s prey base due to overfishing and
environmental factors.
Suzanne Canja used to watch over Makana with us. Now she spends her
springs and summers as field camp leader for the Monk Seal Project
at French Frigate Shoals, documenting new pups and researching
their mother’s lives. When she heads back up there next month, she
hopes to see some of the youngsters she saw born last summer. But
the prospects aren’t good. She just hopes to see an animal or two
she recognizes.
And I hope to see Makana again sometime soon — with a pup.
