Knowing where to look for the animals helps; this book and the field guides are useful for this. You’ll find that some species are seen only in certain parts of the park, while others roam far and wide. Don’t look for the crocodile in the fresh-water glades—nor for the round-tailed muskrat in the [mangroves]. On the other hand, don’t be surprised to see the raccoon or its tracks in almost any part of the park.
Keep in mind that all species in the national parks are protected by law. Most wild animals are harmless as long as they are not molested. If you encounter an animal you aren’t sure about, simply keep out of its way; don’t try to harm it or drive it off. Always remember that each animal is part of the [Everglades] [community]; you cannot disturb it without affecting everything else.
Air Plants
Long before you have learned to distinguish the major plant [communities], you will be aware of the air plants—or epiphytes—that grow so profusely in [Everglades]. Epiphytes are non-parasitic plants that grow on other plants, getting their nourishment from the air. Best known is Spanish moss, which festoons the trees of the coastal South from Virginia to Texas; this plant is used by the swallow-tailed kite in constructing its beautiful nest. Despite its name, Spanish moss is actually a member of the pineapple family—the [bromeliads]. Bromeliads are the most conspicuous of the park’s air plants. The epiphytic orchids, though less common, are celebrated for their beauty; their fame, unfortunately, has led to their widespread destruction. There are also epiphytic ferns, trees, and vines; and one cactus, the mistletoe cactus, has taken to the air.
Air plants are highly specialized for making a living under crowded conditions; there are more than 2,000 species of plants competing for sun and water in southern Florida. The epiphytes have adapted to the problem of space by growing on other plants. Their roots, although they absorb some water and minerals, are primarily anchors. Living in an atmosphere that fluctuates between drought and humidity, they have evolved several water-conserving tricks. Some have a reduced number of leaves; others have tough skins that resist loss of water through transpiration; still others have thick stems, called pseudobulbs, that store moisture. The [bromeliads] are particularly ingenious: many have leaves shaped in such a way that they hold rainwater in vaselike reservoirs at their bases. Mosquitoes and tree frogs breed in these tiny reservoirs, and in dry periods many arboreal animals seek the dew that collects here.
Most of the orchids and [bromeliads] grow in the dimly lit tropical hardwood [hammocks] and cypress [sloughs]. A few species, however, having adapted to the sunlight, live on dwarf [mangroves] and the scattered buttonwoods, pond apples, willows, and cocoplums of the glades. The butterfly and cowhorn orchids are sun lovers, as are the twisted, banded, and stiff-leaved bromeliads. All have adapted to the sun with dew-condensing mechanisms or vases at the bottom of the clustered leaves.
