An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year.

Temperatures in Honduras are not as high as might be expected from its tropical location of 15 to 16 degrees north of the equator. The low is 69°F (20.5°C)to a high of 85°F (29°C)
Seasons are defined by the distribution of rainfall, which varies throughout the year. January to May marks the dry season, and June to December marks the wet season, when most of the country's annual average rainfall of 200 inches occurs.

In Honduras wild animals have protected habitats in the country's many national parks and biosphere reserves. Despite this many animals that live in Honduras are endangered: the manatee, the iguanas ofUtila Island, the Central American tapir, and the giant anteater, among others. Even the country's national bird, the scarlet macaw (a type of parrot) is on the endangered list. The chief cause is illegal deforestation. Increased enforcement of logging laws and the benefits of ecotourism are helping to limit the tree loss, but deforestation remains a major concern.

Not all the animals that live in Honduras are creatures you would hope to run into. Crocodiles and poisonous snakes are common in the rainforests. It is always unwise to enter the Honduras jungle without a guide

Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests.
Honduras's high rate of deforestation stems from its poverty. Despite its natural wealth, both mineral and biological, Honduras is one of the poorest countries in Central America. Deforestation results from agricultural colonization by subsistence farmers, clearing for cattle pasture, collection of fuelwood (65 percent of the country's energy comes from fuelwood), mining activities, timber harvesting, and forest fires.
Illegal logging is a major problem in Honduras. By some estimates, as much as 85 percent of timber production in the country is illegal. Tropical forests are found near the equator between the Tropic of Capricorn and Tropic of Cancer. The latitude range for tropical rain forests is 15° to 25° North and South of the equator. The top soil is only 3-4 inches thick and of poor quality. Nutrients are mainly found in a layer of decomposing leaf litter—also called a root mat—which is quickly broken down by various species of decomposers (insects, bacteria, and fungi). The heat and humidity further help to break down the litter. This organic matter is then just as quickly absorbed by the trees' shallow roots.

Different animals and plants live in different parts of the rainforest. Scientists divide the rainforest into strata (zones) based on the living environment. Starting at the top, the strata are:
EMERGENTS: Giant trees that are much higher than the average canopy height. It houses many birds and insects.
CANOPY: The upper parts of the trees. This leafy environment is full of life in a tropical rainforest and includes: insects, birds, reptiles, mammals, and more.
UNDERSTORY: A dark, cool environment under the leaves but over the ground.
FOREST FLOOR: Teeming with animal life, especially insects. The largest animals in the rainforest generally live here. Understory Rainforest Food Web Why is the Rainforest Inportant to Humans? Amazon rainforests produce about 40% of the world's oxygen.

Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and producing oxygen, upon which all animals depend for survival. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet. Rainforests:
provide a home to many plants and animals; maintain the water cycle
protect against flood, drought, and erosion;
are a source for medicines and foods; support tribal people; and are an interesting place to visit Central American Tapir Ocelot Fun Facts Honduras has borders on both the Pacific and Atlantic oceans.
The Bay Islands sit on the second largest coral reef in the world.
The national flower of Honduras is the Rhyncholaelia digbyana (formerly known as Brassavola digbyana)
The national mammal is the white-tailed deer, the national bird is the scarlet macaw
There are 110 mammal species in Honduras. Half are bats
Honduras, is a seasonal feeding site of the whale shark – the world's largest fish.
A storm of sardines! A tempest of tilapia! In Honduran folklore, the Rain of Fish -- La Lluvia de Peces in Spanish – is a phenomenon occurring in the Department of Yoro, where a massive storm results in hundreds of live fish flopping all over the ground. Apparently locals take the fish home, cook 'em up, and eat them.
It’s completely normal to find blonde haired, blue eyed Hondurans on the bay islands. They are direct descendents of the British Pirates that came here over 500 years ago. Whale Shark White Tailed Deer Scarlet Macaw Animals Iguana The End
