A BIT OF ST. JOHN GEOGRAPHY . . . The 12,600 acres of paradise
appeared above sea level approximately 120 million years ago and,
primarily volcanic in its origin, it has a varied terrain offering
moist subtropical forests as well as arid desert vegetation.
St.
John is the most mountainous of the US Virgin Islands and unlike
St. Croix there is very little coastal plains. St. John is the most
mountainous of the US Virgin Islands. Its highest point is Bordeaux
Mountain, 800 feet at road level and 1277 feet at the top. Hiking
the extra 477 feet rewards you with a tremendous ocean view and
strikingly cooler temperatures.
Today's
forests are vastly different from the ones in the early colonial
period which were subsequently cleared for crops. Many of the slow
growing hardwood trees that originally covered the island are rare
now in the second and third growth forests. The annual rainfall
on the island can vary from 45-55 inches in the moist forest areas
to 25-35 inches in the drier parts. The moist forests can be found
mostly along the island's north shore and at higher interior island
elevations where evergreen and deciduous trees can grow as high
as 75 ft or more. The eastern and southeastern areas and the low
lying coastal areas have a much dryer forest vegetation with many
sorts of cactuses. Along the shoreline you will find the mangrove
forests - where mangroves grow in the ocean, their roots protecting
the shorelines and acting as havens for many marine creatures.
The clear warm waters surrounding St. John support a diverse and
intriguing complex of coral reefs. The term coral reef refers to
an integrated marine community, a functioning assortment of creatures.
Sunlight, clear water and the warmth, between 70 and 80 degrees,
along with the cleansing water currents nurture the slow growth
of a coral colony. Anchors, a swimmer's flipper, and the runoff
of sediment from shore edge development can destroy instantly what
has taken decades, even centuries to grow. Preservation of the reefs
is one of the Virgin Islands National Park's primary goals.
February,
March and April the winds blow away from the islands causing the
driest months. Around May the winds shift back flowing again towards
the islands and eventually by August they are loaded with moisture
bringing the much needed rain. With the exception of Cruz Bay all
the water for the island's inhabitants is either collected from
the roofs and routed to the cisterns or transported over by ferry
from St. Thomas.
There are over 800 species of plants on St. John many sporting
vividly colored flowers such as the large and showy Prickly Cactus
blossoms. The tall and aromatic Frangipani trees and many brightly
colored Hibiscus plants. Tropical fruit trees such as guavaberry,
sugar apples, mangos, and bananas are also in abundance.
St. John is a sanctuary for animals as diverse as sea turtles,
and reef fish, mongoose, deer, gecko and iguana lizards. More than
30 species of tropical birds breed on the island including the The
Bananaquit, also known as the Sugar Bird, the black smooth-billed
ani, and two species of Caribbean hummingbirds. Many warblers and
other birds seen in continental United States in the summer spend
their winters in the dense forests.
The Sugar Bird is the official bird of the Virgin Islands and can
be seen in large numbers swooping into the open aired restaurants
offering bowls of sugar to attract them.
