SEA TURTLE
NESTING SEASON
IS MAY 1
THROUGH OCTOBER 31, 2007
Each summer, Florida
beaches host the largest gathering of nesting sea
turtles in the United States.
Female sea turtles emerge from the surf to deposit eggs in sand nests
and 50-65
days later, tiny hatchlings struggle from their nests and immediately
scramble
toward the ocean. Moving quickly from the nest to the sea is
critical for
the survival of hatchling sea turtles. Nearly all of this
activity takes
place under cover of darkness and relies upon a naturally lit beach,
where the
lighter seaward horizon guides the hatchlings to the ocean.
On beaches
where artificial lighting is visible, the hatchlings’ journey
to the sea is
disrupted. Hatchling sea turtles emerging from nests are
strongly
attracted to light sources along the beach. Consequently,
artificial
lighting visible on a beach causes the hatchlings to move away from the
ocean
in the wrong direction toward porch lights, interior lighting visible
through
windows, parking lot lighting, walkway lighting, and street
lights. Lost
and disoriented, they soon die from dehydration, heat exhaustion or are
crushed
on nearby streets or parking lots. Quite literally, a single
light left
on near a sea turtle nesting beach can misdirect and kill hundreds of
hatchlings.
Artificial lighting also
affects the nesting of female sea turtles. Studies show that
brightly
lighted beaches are less frequently used as nesting sites.
Adult female
sea turtles attempting to return to the sea after nesting, like
hatchlings, can
also be lead astray by nearby lighting.
Please make
sure that your outside and inside lights are not visible from the
beach. In addition, please remember to bring all beach
furniture, toys, etc., up close to your house or condominium building
each night.

Sea turtles are
protected under the U.S.
Endangered Species Act as well as Florida
Statutes. The Fort Myers Beach Land
Development Code (LDC) contains sea
turtle protection provisions governing the following development,
activities
and equipment.
· Electric
signs and signs near the beach – LDC Sec. 30.93 (c)(2); and
Sec. 30.55 (b)(2)(c)
· Parking lot
lighting – LDC Sec. 34-2015 (4)
· New
and existing development – LDC Sec. 14-75 &
14-76
· Beach
furniture and equipment – Sec. 14-78 (3)
· Jet-ski
transport – Sec. 14-78 (4)
· Mechanical
beach raking – Sec. 14-78 (2)
· Parking –
Section 14-78 (c)
Land Development Code
guidelines for mitigation and abatement of prohibited artificial
lighting can
be found in the LDC Sec. 14-79.
Solutions
to Decrease Light-Pollution Affecting Sea Turtles
– HOW YOU CAN HELP
There
are ways that beach
front property owners can modify their lights to prevent them from
being seen
from the beach. The following is a list of suggestions (these
solutions may
need to be used in combination with one another in order to prevent sea
turtle
disorientation).
- Turn off unnecessary lights. Don’t use
decorative lighting (such as runner lights or uplighting of vegetation)
in areas that are visible from the beach and permanently remove,
disable, or turn off fixtures that cannot be modified in any other way.
- For lights that can be
repositioned, face them away from the
beach so that the light source is no longer visible.
- Shield the light source. Materials such as aluminum
flashing can be used as a shield to direct light and keep it off the
beach. When shielding lights, it is important to make sure they are
shielded from all areas on the beach (including from either side and on
top), and not just from the beach directly in front of the light. Black
oven paint may be used as a temporary solution.
- Light sockets with an exposed
light source (such as plain bulbs) should be replaced with fixtures
that are specially made to recess and/or the light source should be
shielded.
- Replace fixtures that scatter
light in all directions (such as globe lights or carriage lights) with
directional fixtures that point down and away from the beach.
- Replace lights on poles with
low profile, low-level lamps so that the light source and reflected
light are not visible from the beach.
- Replace incandescent,
fluorescent, and high intensity lighting with the lowest wattage
low-pressure sodium vapor lighting or replace white incandescent bulbs
with the yellow "bug" light variety of 40 watts or less.
- Plant or improve vegetation
buffers (such as sea grapes and other native beach
vegetation) between the light source and the beach to screen light from
the beach.
- Use shielded motion detector
lights for lighting, and set them on the shortest time setting.
- To reduce spillover from
indoor lighting move light fixtures away from
windows, apply window tint to your windows that meets the 45% inside to
outside transmittance standards for tinted glass (you’ll save
on air conditioning costs too!), or use window treatments (blinds,
curtains) to shield interior lights from the beach.
Remember
the three
‘golden rules’ for avoiding artificial lighting
effects on the beach:
- Keep it Low -
keep lights at a low level/height (directed lighting) and use low
wattage lighting.
- Keep it
Shielded – use lighting fixture shields
- Keep
it Long – use
long wavelength lighting such as low pressure sodium bollard fixtures,
LED
lighting, light bulbs in a deep red or amber color.
