Cloud Forests

What Is A Tropical Montane Cloud Forest?

There is not an agreed upon definition of what makes a cloud forest a cloud forest. However, cloud forests are generally defined by their constant immersion in a layer of clouds. Here, we are interested in cloud forests that form along mountainsides (generally between 1,000 and 3,000 meters (3,300-9,850 feet), but as low as 500 meters (1,650 feet)) in the Tropics (between the latitudes 23°N and 23°S).

How Do The Clouds Form?

The process of forming clouds takes several steps. First, water evaporates off the sea or land surface, forming a warm mass of air. Next, the air mass is carried by winds until it strikes the side of the mountain. As the wind forces the mass of air and water vapor up the side of the mountain, it cools, and the water vapor begins to condense, forming water droplets that appear as clouds.

Where Do They Occur?

Tropical montane cloud forests are very rare and represent only a fraction of the world's remaining tropical forests. The best current estimate is only 0.14% of the entire land surface of the planet. In addition to Central America, tropical montane cloud forests are found in South America, Africa, Southeast Asia, and the Caribbean. There's even cloud forest on the side of Mt. Kilimanjaro in Tanzania.

Since they are almost always covered in clouds, tropical montane cloud forests have very unique climate conditions. This affects the plants and animals living in the forest and the ecosystem as a whole.

What Makes Them Special?

Tropical montane cloud forests are home to an incredible number of plant and animal species. In Monteverde, Costa Rica alone, there are approximately 750 tree species, and this number will likely grow as rare new species are discovered. In comparison, all of North America (north of Mexico) has approximately 1000 tree species. Many tropical montane cloud forests have high rates of endemism (species that don't occur anywhere else).

Why Are They A Conservation Priority?

These rare ecosystems are valuable for their beauty and biodiversity conservation, but they also have value to those living around them. They maintain water cycles, provide food sources, and are often attractive centers of tourism and thus provide people with their livelihoods.

Unfortunately, tropical montane cloud forests are threatened by a number of pressures. These include the cutting of forest for wood and cattle grazing, climate change, hunting, and tourism. As people need more and more resources to survive, the threats to these forests increase.

Climate change is among the biggest concerns in the tropical montane cloud forests. New research suggests that the timing, strength, and frequency of cloud cover is changing due to rising temperatures. These cloud cover changes have been associated with local extinctions and changes to populations of rare bird, frog, and salamander populations. New climate models suggest that in the next 50-100 years, cloud forests may get warmer and drier at rates that they have never before experienced.

Do flying fish really fly?

As the name flying fish heard we think of this

But it is actually this

so the question is do they fly.YES flying fish flies.There are about 50 species of flying fish. They are found in tropical and warm temperate oceans, moving into temperate seas with seasonal warming of water.
They are members of family exocoetidea and have large pectoral fins which spread wide and used as wings to glide once they break out the sea surface.

Flying fish can be seen jumping out of warm ocean waters worldwide. Their streamlined torpedo shape helps them gather enough underwater speed to break the surface, and their large, wing-like pectoral fins get them airborne.

Flying fish are thought to have evolved this remarkable gliding ability to escape predators, of which they have many. Their pursuers include mackerel, tuna, swordfish, marlin, and other larger fish. For their sustenance, flying fish feed on a variety of foods, including plankton.

Gliding Ability

The process of taking flight, or gliding, begins by gaining great velocity underwater, about 37 miles per hour. Angling upward, the four-winged flying fish breaks the surface and begins to taxi by rapidly beating its tail while it is still beneath the surface. It then takes to the air, sometimes reaching heights over 4 feet and gliding long distances, up to 655 feet. Once it nears the surface again, it can flap its tail and taxi without fully returning to the water. Capable of continuing its flight in such a manner, flying fish have been recorded stretching out their flights with consecutive glides spanning distances up to 1,312 feet.

Fishing

Flying fish are attracted to light, like a number of sea creatures, and fishermen take advantage of this with substantial results. Canoes, filled with enough water to sustain fish, but not enough to allow them to propel themselves out, are affixed with a luring light at night to capture flying fish by the dozens. There is currently no protection status on these animals.
