This national park was founded on of
January the 25 of 1971, and extended to its present size
of 6,506 you have in 1993. The volcano of Poas receives
the greatest number from visitors to any park in the country.
The spectacle of the main crater, the developed lake Dull,
natural signs, and a great natural diversity makes this
park only. The forests with a great amount of epiphytes
and ferns of the tree cover it, along with the umbrella
of the poor man. The park is also an important power plant
of the hydroelectric and geothermal generation. |
Historycal Background
The eruptions of the volcano of Poas are known to have happened
from of 1747 in which the Spanish governor Juan To moan wrote
on his activity. Other dates of the activity include 1834 in which
oersted of Andrés registered underground blasts, and the
sent ash of the volcano separated stops up to 30 miles. One of
1910 is considered to be the greatest eruption of the mud, of
gases, the pumice stone, and the ash that will be documented.
From the 1952/54, the main period last of the activity with great
clouds of the ash and the rock that shone intensely accompanied
by the underground rumbling, they formed the present structure
of the volcano. In 1994 there was one more an eruption smaller
than it added some rocks to the ' beach ' around the crater and
perceivably increased the production of the sulfuroso gas.
Flora and fauna
The Life Zones represented in the park are the Mountain Rain Forest
and Very Humid Low Mountain Forest. There are four principal habitats.
The Cloud Forest surrounds Botos Lake and the back part of the
Potrero Grander; here the predominant species are wild papaya,
pitch apple, oak, and two species of ttsta. Along the edges of
the Caribbean side, the forest is taller and very wet, with numerous
palms, tree ferns, and epiphytes. Elfin Forest is found along
the Main Crater-Botos Lake trail; the main species are pitch apple,
ardisia compressa, and Alzatea verticillata. The arrayanes are
predominant near the point overlooking the crater and on the first
stretch of the natural Botos Lake trail; in a few areas near the
crater there is little vegetation except for a few tolerant colonists
like bracken ferns. Although larger animals are scarce, the avifauna
is diverse and abundant. A total of 79 species of birds have been
identified, including various hummingbirds, Black Guan, Resplendent
Quetzal, Rufous-collared Sparrow, Sooty Thrush, Emerald Toucanet,
Large-footed Finch, and Yellow-thighed Finch. Few mammals are
likely to be seen, though weasels, rabbits, squirrels, and coyotes
are present, along with frogs, toads, salamanders, snakes, and
insects.
Geology and climate
Poás is a volcano with a semiconical shape, with multiple
calderas at its summit. At the bottom of the crater there is a
lake that is full of sulphur and acids; as it gets dry sulfur
emissions increase producing acid rain. North of the active crater,
the Von Frantzius cone is the oldest eruptive center at the top
of the massif. On the southeast side, lies another collapsed cone,
filled by rainwater to form the Botos Lake. The Poas Volcano’s
activity, although consistent, At the Poas Volcano the rainy season
is from May thru November with minimal precipitation the rest
of the year. Fog and mist are typical of the site, particularly
in the afternoon. The average temperature is 12 degrees and rainfall
is 3,500 mm.
