Tropical forest

“ In many parts of my Journal, I have expressed an opinion that travellers have exaggerated the beauty and brilliancy of tropical vegetation, and on a calm review of all I have seen in the districts I have visited, I must repeat it.
There is grandeur and solemnity in the tropical forest, but little of beauty or brilliancy of colour. The huge buttress trees, the fissured trunks, the extraordinary air roots, the twisted and wrinkled climbers, and the elegant palms, are what strike the attention and fill the mind with admiration and surprise and awe. ”

“ Rocks and islands are adorned with the luxuriant vegetation of the tropical forest; a perpetual mist hovers over the waters, and the summits of the lofty palms pierce through the cloud of spray and vapour. ”

“ The tropical forests, again, are characterized by a remarkable uniformity and sombreness which gives them an aspect quite unlike that of European woods. The vast cylindrical trunks of the great forest trees, rising like pillars from the midst of ferns and lesser growths, support a lofty roof of leaves. ”

“ To anybody accustomed to travelling in equatorial countries it seems amazing, on returning to civilization, to find what curious notions people have of the tropical forest. Even in the case of writers of distinction I could quote many passages which are painfully ridiculous. One of the greatest modern Italian writers, for instance—who, by the way, in one of his latest novels, copied almost word for word many pages from my books—added the poetic touch that in the tropical forest flowers were found so large that they could not be picked, and fruit so enormous that no human tooth could bite it! ”

“ It is on the roadside and on the rivers' banks that we see all the beauty of the tropical vegetation. There we find a mass of bushes and shrubs and trees of every height, rising over one another, all exposed to the bright light and the fresh air; and putting forth, within reach, their flowers and fruit, which, in the forest, only grow far up on the topmost branches. Bright flowers and green foliage combine their charms, and climbers with their flowery festoons cover over the bare and decaying stems. ”

“ This great forest, which extends for hundreds of miles along the slopes of the Himalaya, reaches up from the plains to the snows. In the lower part it is a truly tropical forest, and about a tropical forest there is something peculiarly mysterious. A strange stillness is over all. Not, indeed, the absolute silence of the desert, where literally not a sound is heard; for here in the forest, even during the hot noonday quiet, there is always the purring of insect life. ”

“ The bushy trees, with their black stems and ragged foliage, are destitute of the beauty so lavishly bestowed even on the weeds of this fertile soil. The tangled splendour of the wild jungle, which presently borders the track, demonstrates the immense difficulty of pioneering in a tropical forest, where the interlacing boughs of the myriad trees, with their impenetrable screen of climbing parasites, make perpetual walls of living green, defying human progress. ”

“ As we come closer under the mountains the base emerges from the haze and the line of snowy peaks disappears behind the nearer outer ranges. Then we come to these ranges themselves, which rise with considerable abruptness out of the level plains with very little intermediate modulation of form, and we find them densely clothed in forest—true, rich, luxuriant, tropical forest with all the delights of glistening foliage, graceful ferns and palms, glorious orchids, and brilliant butterflies. ”

“ But all the other sights they had seen were forgotten when at last they came to the huge botanic station. Here they drove for miles through a veritable tropical forest among gigantic trees, under trailing lianas, beside jungle streams, all of which, as far as appearances went, might have been in the very heart of South America. But everywhere the red earth roads were as smooth and well kept as asphalt, the grass was green and velvety, beds of gorgeous flowers were all about, and all the trees and plants were carefully labeled. ”

“ Below, instead of shrubby palms, large-leaved heliconias, and curious melastomae, the ground was bare and brown from the fallen leaves of the pines, excepting that in some places light grass had sprung up; in others the common bracken-fern of Europe. All that I thought characteristic of a tropical forest had disappeared; and the whistling of the wind through the pine-tops, which I had not heard for years, carried me back in imagination amongst the Canadian forests. ”

“ Occasionally we noticed brilliant blossoms lying at our feet, fallen from some creeper, stretching itself in light and air over the tree-tops; and at one point we picked up and enjoyed some delicious suwarri nuts. But, taken as a whole, primeval tropical forest is a hostile thing. It can harbour no fairies, though there might be demons and goblins. ”

“ No one who has ever seen both our temperate forests and those in the tropics can fail to be impressed with the difference between them. Not only for the different plants in them, but for their wholly different aspect, tropical and temperate forests stand far apart as an expression of the forest covering the earth. Not all of us realize, however, that the heat of the tropics is not the deciding factor in the luxuriance of those dim jungles, and that a rainfall far above anything occurring in the United States is even more important. ”

“ The difference between a tropical forest and that of our temperate zone, which at once challenges the notice of the traveler, is that trees of the same families do not characterize any particular spot. ”

“ The beach, the river-swamp, the forest, the grass-lands present their characteristic forms of plant-life. Five-sixths of the Republic are covered with the densest tropical forest; an enormous variety of gigantic trees grow closely crowded together and are bound by a tangle of vines and creeping plants into an almost impenetrable mass. Nowhere perhaps in the world is there a more typical tropical forest. ”

“ Here we had at last the tropical vegetation in its fullest glory. Nothing can exceed the prodigality and luxuriance of nature when a vertical sun beats down on fields and forests and jungles that have been drenched for months in rain. Vegetation of every kind springs up, as in the temperate zone it appears only when forced in heated conservatories (as in the Duke of Devonshire's gardens at Chatsworth) , and the land waves with these luxuriant growths. In the forest creeping plants wind round the tall trunks, and vines hang in festoons from tree to tree. ”

“ Among the plants are wood-sorrel, bramble, nut, spiraea, and various other South European and North American genera.
The climate is no longer stifling and the leeches have disappeared. We miss many beauties of the tropical forest. But, with the vegetation more and more resembling what we are accustomed to in Europe, we are feeling more at home. The path winds through cool and pleasant woods, following the varying contour of the mountain-sides. We are no longer oppressed by the strangeness of the life around us. At almost every turn we come across something new yet not wholly unfamiliar. ”

“ The first view of high mountains, the first glimpse of the broad ocean, the first sight of a tropical vegetation in all its fulness, are epochs in one’s life. This wonderful South American forest is so matted together and intertwined with gigantic parasites that it seems more like a solid, compact mass of green than like the leafy screen, vibrating with every breeze and transparent to the sun, which represents the forest in the temperate zone. ”

“ Tropical rainforest is the climatic vegetation in the tropics wherever rainfall and low temperatures are not limiting factors. But any definition of tropical rainforest begs the question: 'what is a forest?' As we will show, it is far more than a collection of trees; all forests contain non-tree plant communities such as "tree" ferns and bamboo, and the forest ecosystem is comprised of plants, animals, microbes and soils and their interrelationships. ”

“ THE DREARY JUNGLE
Many people have the idea that a tropical forest is full of gorgeous flowers, about which brilliant butterflies are constantly flitting and birds of splendid plumage flash from tree to tree. This idea is no doubt due in a great measure to the habit of gathering together in hothouses the flowering plants of all the Tropics, though they may have come from Central America, from Africa and from Borneo or Java. It is true that there are many splendid birds, but the vegetation is so dense that you seldom, if ever, see them ”

“ There is something in a tropical forest akin to the ocean in its effects on the mind. Man feels so completely his insignificance there, and the vastness of nature. ”

“ The tropical forest, which represents the maximum of plant luxuriance, stimulated by the heaviest rainfall, greatest heat and strongest light. These divisions merge one into the other, and admit of almost indefinite subdivision, while they are subject to great modifications by human interference in clearing and cultivating. Plants exhibit the controlling power of environment to a high degree, and thus vegetation is usually in close adjustment to the bolder geographical features of a region. ”

“ Two things are noteworthy in comparing tropical forests with those of colder regions: the diversity of the vegetation, and the intensity of the struggle for existence. In the temperate or frigid regions of the earth which are forested we are accustomed to see one species or genus of trees dominate all other plants and become a "climax forest," e. ”

“ Few people in this country have any adequate conception of a tropical forest, and, consequently, are scarcely prepared to see whole races of animals constructed specially for a residence in the umbrageous wilderness within its pathless precincts. ”

“ At the base of such a mountain we have all the luxuriance of growth characteristic of the tropical forest,—the Palms, the Bananas, the Bread-trees, the Mimosas; higher up, these give way to a different kind of growth, corresponding to our Oaks, Chestnuts, Maples, etc.; as these wane, on the loftier slopes comes in the Pine forest, fading gradually, as it ascends, into a dwarfish growth of the same kind ”

“ Some tropical forests exhibit dense foliage from the forest floor to the topmost leafy layer; and the traveler finds the mass of foliage almost impenetrable. Other tropical forests afford a free passage and a clear outlook. It is obvious that tropical forests will eventually be subdivided into plant associations; but the difficulties of determining the relative abundance of the species of plants in the upper layers of tropical rain and monsoon forests are very great. ”

“ But under all circumstances, sheltered from heavy winds or in bleak exposure to them, well fed or starved, even at its highest limit, 10,500 feet above the sea, on exposed ridge-tops where it has to crouch and huddle close in low thickets, it still contrives to put forth its sprays and branches in forms of invincible beauty, while on moist, well-drained moraines it displays a perfectly tropical luxuriance of foliage, flowers and fruit. ”

“ What strikes one most in riding or walking through a tropical forest of Central America is the mixed nature of the vegetation. Between the low fringe of sea-coast, where the mangroves have full sway, and the lofty hilltops, where the pines and oaks abound, one can nowhere give a name to the forest from the predominence of any particular tree. ”

“ On such natural exposures as steep mountain sides, the banks of rivers, or ledges of precipices, and on the margins of such artificial openings as roads and forest clearings, whatever floral beauty is to be found in the more luxuriant parts of the tropics is exhibited. But even in such favourable situations it is not the abundance and beauty of the flowers but the luxuriance and the freshness of the foliage, and the grace and infinite variety of the forms of vegetation, that will most attract the attention and extort the admiration of the traveller. ”

“ Every pond, large or small, is sure to be the resort of tall wading-birds and waterfowls. Presently we come upon a spot where the earth is flecked with golden sunlight, shifting and evanescent, sifted, as it were, through the gently vibrating leaves, softly gilding the sombre drapery of the forest. There is nothing monotonous in a tropical wood; individual outlines and coloring are in endless variety. The contrasts presented in a circumscribed space are infinite, while a never-fading bloom overspreads the whole. ”

“ Clothe the mountainous plateaux next—both of them—with endless forest,—not grand umbrageous forest like the forests of South America, nor matted jungle like the forests of India, but with thin, rather weak forest,—with forest of low trees, whose half-grown trunks and scanty leaves offer no shade from the tropical sun. Nor is there anything in these trees to the casual eye to remind you that you are in the tropics. Here and there one comes upon a borassus or fan-palm, a candelabra-like euphorbia, a mimosa aflame with color, or a sepulchral baobab. ”

“ The tropical forest is full of climbing plants bent upon reaching the sunlight. But some climb by coiling round the trunk of a tree like a snake, some swarm up it by holding on with claws, some ascend by means of adhering aerial roots, and some reach what they want by pushing through a tangle of branches spreading out arms and hauling themselves up. And when plants have attained maturity and flowered, the flowers employ numberless ways of attracting insects for the purpose of fertilisation. ”
