FLOATING FOREST
As many as seven different species ofmanglar(mangrove) thrive in Costa Rica. Compris-
ing the vast majority of tropical coastline, mangroves play a crucial role in protecting it
from erosion. Mangroves also serve as a refuge for countless species of animals, espe-
cially fish, crab, shrimp and mollusks, and as a sanctuary for roosting birds seeking pro-
tection from terrestrial predators.
Mangroves are unique among plants in that they have distinct methods for aeration
(getting oxygen into the system) and desalination (getting rid of the salt that is absorbed
with the water). Red mangroves, which are the most common species in Costa Rica, use
their web of aboveground prop roots for aerating the plant's sap system. Other species,
such as the black mangrove, have vertical roots that stick out above the mud, while but-
tonwood mangroves have elaborate buttresses.
The most amazing feature of the mangrove is its tolerance for salt, which enables the
plant to thrive in brackish and saltwater habitats. Some species, such as the Pacific coast
black mangrove, absorb the salinated water, then excrete the salt through their leaves
and roots, leaving behind visible crystals. Other species filter the water as it is absorbed -
the mangrove root system is so effective as a filter that the water from a cut root is drink-
able!
Despite their ecological importance, mangrove habitats the world over are being in-
creasingly threatened by expanding human habitats. Furthermore, mangrove wood is an
easily exploitable source of fuel and tannin (used in processing leather), which has also
hastened their destruction. Fortunately in the Humedal Nacional Térraba-Sierpe, this fra-
gile yet vitally important ecosystem is receiving the respect and protection that it de-
serves.
