April
25, 2003 is National Arbor Day
April
2003
On
January 4, 1872, J. Sterling Morton first
proposed a tree-planting holiday to be
called "Arbor Day" at a meeting
of the State Board of Agriculture in Nebraska.
The date was set for April 10, 1872. Prizes
were offered to counties and individuals
for planting properly the largest number
of trees on that day. It was estimated
that more than one million trees were
planted in Nebraska on the first Arbor
Day.
Arbor Day was officially proclaimed by
the young state's Gov. Robert W. Furnas
on March 12, 1874, and the day itself
was observed April 10, 1874. In 1885,
Arbor Day was named a legal holiday in
Nebraska and April 22, Morton's birthday,
was selected as the date for its permanent
observance. Today the most common date
for the state observances is the last
Friday in April, and several U.S. presidents
have proclaimed a national Arbor Day on
that date.

Rapid
Temperature Changes Cause More Brilliant Fall Foliage
November 2002
The
green color of leaves in the summer is from the chlorophyll that
helps the tree or plant turn sunlight into food. In the fall trees
and plants stop making chlorophyll. Then the other pigments in the
leaf show through. The leaf may then show the yellow color of the
pigment xanthophyll or the orange-red tones of carotene (this is
what makes carrots orange, too). There are also a group of red and
purple pigments called anthocyanins. The color of the autumn leaf
depends on which of the pigments is most plentiful in the leaf.

Facts and History
The gopher tortoise is a keystone species
July
2002
 |
Sandy,
a Levy County gopher
tortoise, heads for his favorite watering hole. |
Gopher
tortoises dig burrows -- typically ranging in size from 20 to 30
feet long and from six to eight feet deep -- with their shovel-like
front legs. Biologists have found some burrows as big as 40 feet
long and 10 feet deep! The burrows are found in dry places such
as sandhills, flatwoods, prairies and coastal dunes or in human-made
environments such as pastures, grassy roadsides and old fields.
The gopher tortoise is a keystone species, meaning its extinction
would result in measurable changes to the ecosystem in which it
occurs. Specifically, other animals, such as gopher frogs, several
species of snakes and several small mammals, depend on tortoise
burrows. For the gopher tortoise to thrive, the animal generally
needs three things: well-drained sandy soil (for digging burrows),
plenty of low plant growth (for food) and open, sunny areas (for
nesting and basking). The gopher tortoise is found along the dry
sand ridges of the southeastern Coastal Plain. In Florida, tortoises
are found in the panhandle and along the southeastern coast.

June
21 is the Longest Day of the Year (AKA Summer Solstice)
The
summer solstice, which occurs around June 21, is the longest day
of the year! This is because the Sun gets very high in the sky for
people living in places north of the equator like the United States,
Europe, and China. The Sun stays above the horizon for more than
12 hours on that day.

Governor Jeb Bush proclaimed the month of May as Clean Air Month
and the first week in May as Ozone Awareness Week ~
DEP's
2002 Clean Air Month campaign theme is "ozone awareness".
Florida enjoys good air quality; however, that good quality cannot
be taken for granted. Because air is "invisible," most
people fail to realize that poor air quality can adversely affect
our health as well as business, property, recreation, and tourism--all
of which are the backbone of Florida's progress. The air we breathe
is a vital natural resource. Because many of our daily activities
affect our air quality and many of those effects are detrimental--our
citizens need to know how important it is to protect our air quality.

The cardinal is not a migrant bird
April
2002
Cardinals
are territorial and aggressive birds and often become one of the
dominant feeders at birdfeeders. Their own reflection can trigger
a fight. They search from the ground up for seeds (which they can
easily crush with their conical bill), fruits and berries of several
species of plants, supplemented with insects during breeding season.
At home feeders, they prefer sunflower seeds . Females lay 3-4 pale
green eggs, spotted with red-brown, in a nest that is a deep cup
of loosely woven twigs, vines and plant fibers, mainly built by
the female.

The Zebra Longwing is Florida's official state
butterfly
March
2002
In
1996, Governor Chiles designated the Zebra Longwing as Florida's
official state butterfly. The zebra, easily identified by its long
black wings striped with yellow, is found in all parts of the state
year round. Zebras fly slowly and don't startle easily, making them
easy to follow and observe. A zebra resting at dusk can be gently
coaxed to climb on your finger and to return, unflustered, to its
perch. Zebras roost in groups, returning to the same location each
night. Zebra longwings feed on nectar and pollen. They are the only
butterflies known to eat pollen which is probably why they have
a long lifespan of about six months. If denied pollen, they live
a more typical lifespan of about one month. The Zebra Longwing Photo
Gallery contains pics of zebras sipping nectar on a golden dewdrop
flower and laying eggs on a passion vine as well as Zebra Longwing
caterpillars.

Armadillos are the only mammals in Florida with
an exoskeleton
January
2002
Armadillos
are not native to Florida, but are now common over most of the state.
Armadillos like forested or semi-open habitats with loose textured
soil that allows them to dig easily. They dig burrows for homes
or to escape predators. They eat many insects, or other invertebrates,
and some plants. They most often feed at night, and have very poor
eyesight. Armadillos prolific rooting and burrowing can severely
damage lawns and flower-beds. To reduce armadillo damage to your
lawn keep watering and fertilization to a minimum. Moist soil and
lush vegetation bring earth worms and insect larvae (armadillo candy!)
to the surface of the soil.

Half
the land in the U.S. is owned and managed by 4.7 million farmers
and ranchers
January
2002
Every
year US agriculture introduces into the environment over 900 million
pounds of pesticides in producing food and fiber consumed worldwide.
While contributing to the production of an abundant and affordable
food supply, continued reliance on pesticides, comes at a cost in
terms of harm to people, wildlife and the environment. Concerned
about continued dependence on high-risk pesticides, many farmers
and ranchers are adopting ecologically-based Integrated Pest Management
(IPM) systems as an essential step in reducing reliance on pesticides.
IPM is an information intensive systems approach to managing pests
that relies on a range of preventive tactics and biological controls
to minimize pest damage to crops. Reduced risk pesticides are used
as a last resort if other tactics fail. Accelerating adoption of
ecologically-based IPM systems benefits all creatures that share
the agricultural landscape--wildlife, beneficial insects and microorganisms,
farmers, farmworkers and consumers.

It
is unlawful to shoot or harass vultures in Florida.
January
2002
Two
species of vulture occur in Florida, the turkey vulture (Cathartes
aura) and the black vulture (Coragyps atratus). Turkey vultures
have reddish heads while the heads of black vultures are black.
The turkey vulture holds its wings in a slight "v" while
soaring, whereas the black vulture's wings are held straight. The
tail of the black vulture is usually more fanned out in flight and
is shorter and broader than that of the turkey vulture. The black
vulture flaps its wings more and soars less than its relative. From
below it has whitish patches near the tips of the wings, whereas
the wings of the turkey vulture lack these patches.

Ladybird
beetles, or ladybugs, can be beneficial to your garden
December
2001
These
voracious predators feed on plant eating aphids and a variety of
other pest insects. They are often used to control garden pests
and some farmers use them as a natural way to protect crops without
using pesticides. Adult ladybird beetles are small, round to oval,
and dome-shaped. Most have black markings on red, orange, or yellow
forewings, but some are black. There are over 450 species of ladybird
beetles found in North America, and some 4,500 worldwide. Some are
native and others have been introduced sometimes displacing native
species. Introduced species, including the 7-spotted ladybird beetle
are more aggressive consuming more pest insects. Common ladybird
beetles will consume up to 50 aphids a day, but the 7-spotted lady
beetle can eat 200 per day.

POPs are found almost everywhere-in our food, soil,
air and water
December
2001
Persistent Organic Pollutants (POPs) are toxic substances composed
of organic (carbon-based) chemical compounds and mixtures. They
include industrial chemicals like PCBs and pesticides like DDT.
They are primarily products and by-products from industrial processes,
chemical manufacturing and resulting wastes
Wildlife and humans
around the world carry amounts of POPs in their bodies that are
at or near levels that can cause injury. These pollutants are persistent
in the environment and have the ability to travel through air and
water to regions far from their original source. POPs also tend
to bioaccumulate, meaning they accumulate in fatty tissue of organisms
and dramatically increase in concentration as they move up the food
chain.

The
Florida sand skink is threatened from loss of habitat
December
2001
Skinks
get their name from the family of lizards they belong, "Scincidae."
This word derives from the Latin word scincus and the Greek word
skinkos. Both words mean lizard. The sand skink is found in central
Florida in vegetated areas (particularly in areas where Florida
rosemary grows). It burrows below pine and other ground litter with
adequate moisture beneath the surface. They usually remain underground
and burrow 2 to 4 inches (5 to 10cm) beneath the soil to feed on
insect larvae, beetles, spiders, termites and other ground arthropods.
Larger skink species will eat fruit, snails, or even nestling rodents
and birds.

Every
year, millions of exotic birds are taken from the wild and sold
as pets
The
Wild Bird Conservation Act of 1992 (WBCA) was designed to protect
wild populations of exotic birds from the growing international
pet trade. Each year, millions of wild birds are taken from the
wilds of Asia, Africa, and Latin America and sold as pets. To collect
these birds, trees are often cut down or nest cavities opened with
machetes, resulting in permanent habitat destruction. Up to 80 percent
of birds in trade die before reaching their final destination, as
hundreds of wild birds are frequently crammed into small crates
without sufficient food, water, or ventilation. Excessive trade
and habitat destruction now threaten more than 1,000 species with
extinction. Before the WBCA was enacted, the United States was the
world's largest importer of wild birds, importing more than 7.4
million birds between 1980 and 1991, primarily for the pet market.

Okefenokee Swamp is derived from a Native American
term meaning "trembling ground"
November
2001
Vegetation in the swamp includes cypress forests, water lilies,
brush vines, and Spanish moss. Animal life includes alligators,
deer, wildcats, opossums, raccoons, and more than 50 species of
fish. The swamp is also the winter home for many species of migratory
birds. Native Americans, especially the Seminoles, used the swamp
as a hunting ground until 1850, when an armed United States militia
drove them out of the swamp because they had been conducting raids
on local settlers. Since 1937 most of the swamp has been incorporated
into the Okefenokee National Wildlife Refuge, which is administered
by the United States Fish and Wildlife Service.

Snowy owls, like Hedwig from the Harry Potter series,
are found in Alaska
Like
the owls in the Harry Potter stories, which are used to deliver
important messages from one character to another, real-life owls
can also convey signals about the health of the habitat upon which
they depend as well as the dangers these habitats face. For example,
the snowy owl, which resembles the fictional owl known as Hedwig
in the Harry Potter series, is one of 140 bird species found in
the Arctic National Wildlife Refuge, America's greatest wildlife
sanctuary. This spectacular refuge -- located in the northeast corner
of Alaska's North Slope -- is under threat from the oil companies
that want to drill there. The impacts on sensitive wildlife from
oil exploration could threaten the lives of birds, polar bears,
wolves, caribou and other animals. Oil development in the refuge
could mean an uncertain future for snowy owls and other species
that call the refuge their home.

Only
about half of the original Everglades ecosystem remains
The
Everglades is composed of sawgrass marshes dotted with cypress,
willow and pond apple tree islands, pine rocklands, tropical hardwood
hammocks, mangrove swamps, and coastal estuaries. The Everglades
is home to hundreds of different animals, plants and birds, including
endangered species such as Florida panthers, eastern indigo snakes
and wood storks. It is the only place where both alligators and
American crocodiles live
. Much of the Everglades has been
drained and channelized to accommodate agriculture and urban development.
Changes in water-flow quantity, quality and timing, explosive human
population growth, and invasion of non-native species have seriously
deteriorated the health of the Everglades.

Florida
has 3 squirrel species
Florida
is home to three species of squirrels, the eastern gray squirrel
(Sciurus carlinensis), the fox squirrel (Sciurus niger), and the
southern flying squirrel (Glaucomys volans). The most common in
urban areas is the eastern gray squirrel. Squirrels occur in woodland
and urban areas, especially near oaks and hickories, and are active
during the day, often feeding on the ground. During late summer
squirrels may be seen rolling on the ground, biting themselves,
and jumping up and down. This is usually due to skin irritations
from bot fly larvae, which are parasites that appear as bumps on
the skin, often in places where the squirrel cannot scratch. The
parasite is located only in the skin and does not affect edibility
of the meat in harvested squirrels.

can live up to 30 years. Most Florida black bears live for several
decades. Every two years during January or February, females give
birth to 2 to 4 cubs. Their dens may be high in a tree, in a hollowed
out stumps or in a forest floor protected by vegetation. The cubs
are dependent on the their mother's protection for nearly two years,

The West Nile Virus is transmitted from infected birds
September 7, 2001
The
West Nile Virus is an insect-borne virus that had not been reported
in the Western Hemisphere prior to 1999. Birds are the natural hosts
for this virus, which can be transmitted from infected birds to
humans and other animals through the bites of infected mosquitoes.
Since the fall of 1999, the US Geological Survey (USGS) has been
testing wild birds and mammals for West Nile virus (WNV) infection.
USGS is also incorporating epidemiological data gathered during
WNV outbreaks into maps and geographic-information systems (GIS)
in support of federal, state, and local wildlife agencies, as well
as public health departments and other federal agencies that are
utilizing dead wild birds as sentinels for detecting West Nile virus
activity in their area.

Jaguars are part of the cattle lifecycle
June 18, 2001
Wherever the jaguar lives in close proximity to people, it has generally
been persecuted as a threat to humans and their livestock or pets.
Yet only a few scientific studies have actually tried to assess
how often jaguars prey on cattle. Research suggests that healthy
jaguars can range close to livestock without preying on them. Jaguar
predation in some parts of Brazil accounted for only a small percentage
of cattle mortality; most died from drowning, disease, and starvation.
However, research in Venezuela indicated that cattle made up to
56% of the jaguars' diet
. Part of the Jaguar Conservation
Program focuses on working with ranchers to reduce the conflict
between cattle and jaguars.

Chameleons
can change color in less than 60 seconds
June 11, 2001
The 130-odd species of the Chamaeleonidae family are equipped with
special pigment-bearing skin cells known as chromatophores. Like
different-colored balloons, these cells inflate and deflate according
to circumstances. They are rigged to the animal's nervous system
which pretty much directs the whole show, although other factors,
including light, humidity and temperature, also come into play.
Essentially, a chameleon is like a breathing mood ring, broadcasting
its emotions in living color. Anger, fear, and excitement register
in vivid displays that can dazzle mates, intimidate rivals, or deflect
predators.

About the Florida panther
April,
2001
A
rare Florida panther was recently spotted as far north as the Disney
Wilderness area according to the Nature Conservancy. Observers were
able to tell that it was indeed a Florida panther by the distinctive
crook near the end of its tail and by the black tip on its tail.
Panther tracks are also unmistakable because they show no claw marks.
The sight of this animal was exciting because the total Florida
panther population is estimated at only 60 to 70 individuals. It
is one of the world's most endangered mammals.
