"Hi! Glad you could make
it! Wanted you to have a look at this place while we're hanging around close to
shore. Kelp forests are close to shore just like Coral Reefs, but they need
much colder water temperatures. Our guide in this habitat area will be Gutsy
Garibaldi. She's one of the bravest fish I know! I'll let her explain. Yoohoo!
Gutsy, we're ready for your tour of the Kelp Forest." |
Gutsy Garibaldi "Hi, everybody! It takes a lot of guts |
| to live in the kelp
forest these days! There's all kinds of dangerous activities going on around
here! I'll tell you about them later. For now, I want you to learn about this
'forest beneath the waves'." |

|
| Where Do We
Find Kelp Forests? |
| Kelp grows in both
the Northern and Southern hemispheres. In the Southern hemisphere they occur in
Argentina, through the Straits of Magellan to Chile, off South Africa,
Australia, New Zealand, and many sub-Antarctic islands. In the Northern
Hemisphere they occur from central Baja California to Sitka, Alaska. But the
kelp forests are the most developed off of the California coast, from San Diego
to Santa Cruz. |

What Do We
Know About Kelp Forests? |
|
Kelp
forests occur in cold, nutrient-rich water and are among the most beautiful and
biologically productive habitats in the marine environment. A dependence upon
light for photosynthesis restricts them to clear shallow water and they are
rarely much deeper than 20 to 80 feet. |
|
|
Giant
kelp is one of the fastest growing plants in the world. When conditions are
good, kelp can grow two feet per day! Giant kelp prefers water temperature in
the 50-65 degree (F) range. A giant kelp plant can live up to six years. The
plant is continuously pushing up new fronds to the surface, while the older
fronds break off. Reaching lengths of more than 100 feet, it is the largest
marine algae.

Gas Bladders |
 |
| Stipes |
|
Holdfast |
|
|
 |
The
giant kelp plant has long, sinuous stipes-stems that are supported by
gas-filled bladders (these keep the kelp afloat) located at the base of each
leaflike blade. The plant is anchored to rocky bottoms by its holdfast, a
rootlike mass of tangled haptera. |
|
|
Much
like tree forests on land, kelp forests feature distinct horizontal layers: a
sunny canopy (top layer), a dimly lit middle, and a dark forest bottom.
|
|
 |
When
Macrocystis fronds reach the surface of the ocean they continue growing
horizontally and form a canopy. In the fall and winter, the canopy can become
extremely thick and extensive, creating considerable shade beneath it.
|
|
|
Giant
kelp is very flexible, and can survive all but the most violent storms and
swells. Kelp that has been ripped off it's moorings will sometime gather into
what is known as drift kelp. This kelp floats and drifts with the currents.
This living kelp can, under the right conditions, re-anchor itself in a new
area. |

can also reproduce by way of spores. A single plant can produce trillions of
spores each year. |

"Millions of plants
and animals live |
| in the kelp forest.
There is everything from whales, that go into the kelp forest to hide, to the
playful Sea Otter, that wraps itself in kelp so it won't float away while it
sleeps! Now we're gonna' see some more of the animals and plants that make up
the world of the kelp forest! Gee, I love this place!!

"Isn't it
amazing how many different |
| plants and animals
call the kelp forest 'home'? Well, it's time you learned why my name is
'Gutsy'. Kelp forests are dangerous places to live these days. Everybody thinks
I'm really gutsy to stay in spite of the dangers. I don't think I'm very brave.
I just can't live anywhere else. Used to be everything was really quiet here.
Now the Kelp forest habitat area could be in real trouble! Read on and you'll
find out why." |

What are
the Threats to the Kelp Forests? |
|
Algin--a
substance extracted from kelp--is an emulsifier added to ice cream, salad
dressing, toothpaste, cosmetics and hundreds of other products. The demand for
kelp is ever increasing!
There is concern with both the
"vagueness" of commercial kelp harvesting regulations and the amount of kelp
harvesting. Some countries do not have any regulations at all. The United
States does have regulations. These regulations include the following
stipulations:
- anyone may
harvest kelp as long as they adhere to harvesting
regulations
- kelp must
be harvested by cutting
- it cannot
be cut more than four feet below the surface of the
water
- harvesters
must remove all of the kelp they cut; none can be allowed to
escape
|
There is no
regulation of how much of the canopy of open beds can be taken, except in the
Carmel Bay preserve, where half of the canopy can be harvested every four
months. It is written into the leases of some beds that no more than 50% of a
bed's canopy may be harvested at any one time. However, half of whatever is
left can be harvested the next day - and this can continue until the canopy is
virtually gone. Regulations are loosely enforced by the Department of Fish and
Game. |
|
|
Freshwater runoff, which carries with it all the pesticides,
herbicides and fertilizers used on land to control pests and increase crop
harvest levels is a major threat to the Kelp forest. Pollution of the ocean
waters upsets the delicate balance of the kelp forest. Biodiversity is lost
when species that inhabit the kelp forest die from the toxic chemicals in the
water. As more and more biodiversity is lost, this fragile habitat area could
eventually collapse and be lost forever! |
 
"This is why I wear the mask!!" |
|
|
|
Kelp
forests occur in COLD, nutrient-rich water. Global warming is gradually
increasing the temperature of our oceans. If kelp forests only occur in COLD
water, where the temperature stays at between 50-65 degree (F), increases in
this temperature will adversely affect the kelp forest, endangering its
existence! Human activities are major contributors to global warming. Certain
human activities are causing some greenhouse gases (heat-trapping gases), such
as carbon dioxide, to build up in the atmosphere. Whenever we burn fossil fuels
(gasoline, oil, coal or natural gas), more carbon dioxide is emitted into the
atmosphere. Forest destruction and agriculture also release greenhouse gases.
Greenhouse gases cause an increase in the earth's temperature.

"See what I mean
about dangerous |
| things happening in
the Kelp forest? It's really scary, especially for all of us who live here! You
can help, you know! Really, there are a lot of things you can do even if you
don't live near the ocean. Some of the ways you can help are listed below. I
sure hope you'll not only read them, but you'll actually start doing them!
That's what's important - that YOU DO THEM! |
|
|
Things You Can Do To Help |
 |
Better
regulations regarding the harvesting of kelp need to be enacted and once
enacted, they need to be strictly enforced. In order to make sure the laws
governments enact are in the best interest of the environment and that the laws
are strictly enforced, government officials must be "pro environment". It is
our responsibility to put into office these "pro environment" people. We must
make it our business to know what each candidate's position is on environmental
issues. Once we know this, we must make our voices heard by voting. Do not
stand by silently. GET INVOLVED! |
|
 |
Make
yourself aware of what chemicals you are using in your every day life. Find out
if they are dangerous or harmful to the environment. Whenever possible, do not
use pesticides, herbicides and fertilizers that can be harmful to the
environment. Read the label!! If you are unsure, ask someone. Call your local
health department or forester. |
|
 |
If you
must use toxic chemicals always dispose of them in a safe manner. Leave the
portion that you want to throw away in its original container with the lid
tightly in place. Call your local health department to see if there is a
special pick-up day for toxic chemical waste (some communities have several of
these each year). If your community does not have a special day or if you want
to get rid of the chemicals before the next scheduled special day, put the
containers in a sturdy box and take them to your local health
department. DO NOT
SPILL THE UNWANTED PORTION ON THE GROUND!
DO NOT PUT THE UNWANTED PORTION IN WITH
YOUR REGULAR TRASH! DO NOT
LEAVE UNUSED PORTIONS SITTING AROUND THE HOUSE - IN THE SHED, UNDER THE SINK,
ETC.! |

There
are a number of ways you can help reduce global warming. Below are a few to get
you started and a link to more suggestions and information about global
warming.
-- The next
time you buy a car, get one that gets good gas mileage. Cars and trucks that
get more miles per gallon can help reduce the risk of global
warming. -- We
burn a lot of fossil fuel to heat our homes. Consider using solar power to heat
and light your home. Solar cells supply electricity and solar panels supply
heat without emitting any greenhouse gases or other
pollution. -- Run
your dishwasher only with a full load. Use the energy-saving setting to dry the
dishes. Or better yet, don't use heat when drying. Dry them yourself with a
cloth towel. -- Wash
clothes in warm or cold water, not hot. This uses less natural gas (a fossil
fuel). -- Clean
or replace air filters on furnaces, humidifiers, and air conditioners as
recommended. Cleaning a dirty air conditioner filter can save 5% of the energy
used. -- Buy
energy-efficient compact fluorescent bulbs for your most-used lights.

"Well, that's it.
Pretty neat |
| place, huh? Please,
take some time to try to put into practice the things you can do to help save
the Kelp forest. Get together with the other members of your family and work on
this together. Thanks for taking the time to learn about my home. Come back
again! There's lots more stuff to see and learn! Oh, there's a
picture for you to color if you'd like."

"Was that some
great stuff or what? |
| I was looking at the
suggestions for what we can do to help Gutsy, her friends and their home. I
know I have some light bulbs around my place that could be replaced with
flourescent ones. Since we're finished with our adventure for this month, I
think I'll get the flourescent bulbs and start saving energy right away. Why
don't you take a look around your house and see if you can't do the same thing?
I can hardly wait to see where we're going next time! Hope I'll see you
there!" |
