Anthropogenic Forest Islands and Fallows

Forest islands are common throughout the savannas and wetlands of Amazonia. Forest islands range in size from a few hectares to many square kilometers. Most are raised less than one meter and often surrounded by ponds or a moat-like ditch. Excavations in forest islands in the Llanos de Mojos and Pantanal document their anthropogenic origins and use for settlement, farming, and agroforestry (Erickson 2000a, 2006; Walker 2004; Langstroth 1996). In Bolivia, archaeologists estimate the existence of 10,000 forest islands (Lee 1995; CEAM 2004). The Kayapó of Central Brazil create forest islands (apêtê) of improved soils through additions of organic matter from household middens and recycling of crop debris for intensive cultivation of crops (Posey 2004; Hecht 2003). These anthropogenic features are known for their high biodiversity and agrodiversity of improved soils through additions of organic matter from household middens and recycling of crop debris for intensive cultivation of crops (Posey 2004; Hecht 2003). These anthropogenic features are known for their high biodiversity and agrodiversity.

Listen to William Balée (Historical Ecology: Premises and Postulates):
The landscapes that I call fallows represent a projection of culture onto nature through time. These are living landscapes, even if they have traditionally (and erroneously) been understood to be primary forests by foresters, ecologists, and phytogeographers alike. Fallows exhibit many species, … that occur nowhere else in the terra firme. They are as biologically rich as the high forest in the same region, but they harbour many species unique to them, and many more that only gain ecological importance in areas disturbed by indigenous agroforestry . These species may be collectively considered as semidomesticates.

Getting lost is not an option.

Some snippets concerning wayfinding and knowledge management in the Amazon.

If an Indian loses his way in the forest, the Spirit is the cause. The Caribs, however, know how to circumvent the latter, by making a string puzzle, which is left on the pathway: the object of this puzzle consists in removing, without cutting or breaking, an endless string from off two sticks upon which it has been placed. The Spirit coming along sees the puzzle, starts examining it, and tries to get the string off: indeed, so engrossed with it does he become, that he forgets all about the wanderer, who is now free to find the road again. In this connection, it is interesting to note that Bates speaks of his Indian boy, on the lower Amazon, making a charm to protect them from the Curupari: "For this purpose he took a young palm-leaf, plaited it, and formed it into a ring which he hung to a branch on our track."


The Curupari? The Curupira! Listen to Wikipedia:
The Curupira or Curupura is a male supernatural being who guards the forest in Tupi mythology in Brazil.

He usually takes the form of a boy with (literally) flaming hair and green teeth. His most startling characteristic, however, is that his feet are turned to face backwards.

Its raison d'être is to protect the forest from the destructive habits of man. It happily tolerates those who hunt for food but is infuriated by those who hunt for the pleasure of it and will lay traps and confuse them so that they become eternally lost in the forest. His backward feet, for example, have the effect of confusing hunters who may try to follow his tracks.
Geraldo Reichel Dolmatoff, writing about the Tukano of Columbia, mentions the Boraro, the local name for the curupira.
Some people say that his eyes are red and glowing; others mention his large ears and his curved fangs, similar to those of a jaguar. An evil stench surrounds him and attrachts many large blue butterflies (Morpho) and other insects. All people agree that his feet are twisted, the toes pointing backwards and the heels forward. His knees have no joints, and should he fall he has difficulties in getting up again.
The Boraro has his maloca in the dense forest... much of the time he spends wandering in the forest, sometimes accompanied by his wife, described as a horrible hag with only one breast. 
Occasionally a hunter will come upon a disturbance in the closed-canopy forest, a gap not created by man. These spots are called mirunye poe, the wind's gardens; people avoid them because thes eplaces are visited by the Boraro.   
With a little (?) lateral thinking it is not that had to see a connection with the forest giants of Vico, who also lived in a gap in the forest and whose name was mistranslated into one-eyed. 







Listen Neil L. Whitehead (Cartography in the traditional African, American, Arctic, Australian, and Pacific societies) on the no-need for maps:
In Achuar culture, the concepts of left and right are only used to indicate an immediate and relative position, longer distances being expressed in the time it take to cover them. Beyond a local destination, travel time is counted in days or simply 'very far,' since the events of a temporally extended journey are unpredictable. Distance is measured for architectural purposes but not for travel. To give directions to a place that has not been visited before, people use a system of landmarks that are common across the Achuar habitat and that can be read by anyone. Waterways are structuring elements of this system, but their use requires individual experience of at least a section of that system. By these means, any Achuar can delineate a portion of the network, either in linear fashion, by enumerating successive rivers, or transversely, as if the rivers were being crossed while walking. A given settlement, necessarily built along a waterway, is therefore easily found because it can be fixed using these riverine coordinates. Away from this system, more arcane markers are used to map the environment: a peccary wallow, a salt lick, a soucre of pottery clay or stands of notable flora. Landmarks like these are encountered by returning hunters and help to build and sustain an active knowledge of the spatial characteristics of the environments. Perhaps just as important, "getting lost" is not the disaster it would be to those culturally dependent on cartographic representation. In the absence of this kind of mapping, basic survival skills and orientation techniques are sufficient to see most travellers home.

Amazon Gardening

Gardens, gardening and forestry in the Amazon:

Listen to Phillipe Descola:

For the Achuar view the forest, with its bewildering diversity of plants, as a sort of gigantical botanical garden meticulously tended by Shakaim, a timid and unprepossessing spirit. This segment of the world which evolves and develops independently from human norms, and that we usually call nature, is not for the Achuar a mere object to be socialized, but the ubiquitous subject of social relations. 



From 'Plants, man, and life' (1967) by Edgar Anderson, images above:

 "The garden I charted was a small affair about the size of a small city lot in the United States. It was covered with a riotous growth so luxuriant and so apparently planless that any ordinary American or European visitor, accustomed to the puritanical primness of north European gardens, would have supposed (if he even chanced to realize it was indeed a garden) that it must be a deserted one. Yet when I went through it carefully I could fine no plants which were not useful to the owner in some way or another." 

Listen to Ezra Pound:

The weeder is supremely needed if the Garden of the Muses is to persist as a garden. 

Listen to Michael Williams (Deforesting the earth: from prehistory to global crisis):

An important factor in the domestication process was defecation. The seeds of sweet-corn, tomatoes, lemons, cucumbers, and many more edible plants, as well as fruits of shrubs and trees, can pass intact through the human as well as the animal gut (it may even enhance their reproductive vigour), and can be subsequently dispersed and reproduced. In the case of humans the peripheral latrine areas common to virtually all societies would become new gardens in time
Listen to Michel Conan (Perspectives on garden histories): 

Many anthropologists working in the Amazon Basin have been struck by the resemblance between gardens and the forest. Fifteen months after the forest has been cleared, Achuar gardens have reached their grown-up appearance, and their three-tiered levels of foliage reproduce on a smaller scale and in rather orderly fashion the surrounding forest. Larger-leafed banana trees and papaya trees provide the top cover, cassava plants contribute the larger part of the second cover that prevents the earth from being washed out by rain, and different vegetables and smaller plants provide ground cover. Thus gardens appear as a cultural imitation of the natural forest. One of the most arresting results of the method used by Descola is that it enabled him to show that this is only true to the eye of a Western observer. Actually for the Achuar, the forest is just another garden that is cared for by the spirits who are almost human (they take care of the wild animals as humans do to their own tame animals, and they hunt them in order to eat them as humans do their poultry). He has shown that nature is organized according to social relationships that are identical to social relationships within the household. Nature is perceived along a pattern derived from household life in Achuar society. It turns out that social relationships within their society provide the models for describing nature, rather than nature providing the model for social relationships and artifacts as we would have it.


Listen to Darrell Addison Posey on Kayapó gardening:

Another of the major misconceptions about slash-and-burn agriculture is that fields are abandoned to fallow after two or three years because the soil loses its fertility, and weeds and insects take over. Loss of fertility of the soil, however, is not the factor that determines that agriculture takes a shifting pattern.
Soil analyses shows that the soils are not exhausted after two or even three years. Furthermore, soils are totally rejuvenated after 10-12 years of fallow. Yet no Kayapó field in Gorotire in replanted in less than 15-20 years. Kayapó Field plots in most cases are scattered three to four hours' journey away from the village, although suitable, adequately fallowed, old plots might be only 15-20 minutes away. The Kayapó ordinarily seek to minimize effort and work so that this seems to be a great inconsistency in their cultural pattern.
The Kayapó recognize that the high forest is relatively sparse in animal life, while forest clearing furnish habitat for smaller leafy and bushy plants that attract wildlife. They know that leaving 'abandoned' fields to the natural reforestation sequence artificially creates domains that stimulate wildlife populations. They also know that the more widely their 'abandoned' fields are dispersed, the greater the area available to attract game - and the easier the hunting. Dispersed fields also naturally limit viral, fungal, and insect crop pests.
This sensitivity to forest succession explains why the Kayapó are willing to let close-by old fields remain fallow. Although it might be easier to replant nearby fields more frequently, it would just mean having to go further away to hunt for game and for the essential gathered products from the secondary forest.

Yanomami on the trail

Listen to Darrell Addison Posey on  nomadic agriculture:

Although ‘settled’ for several decades now, the Kayapó have not deserted their semi-nomadic habits entirely. They spend several months each year in the Brazil nut groves living in communal houses; go on frequent collecting and hunting trips; and before major festivals make two- or three-week treks to acquire ceremonial game and feathers.
The Kayapó have never left everything on their journeys to chance, however, but have developed an interesting ‘nomadic agriculture’, which they continue to use today.
While routinely scavenging about the forest, the Indians gather dozens of plants, carry them back to the forest campsites or trails, and replant them in natural forest clearings. The plants include several types of wild manioc, three varieties of wild yams, a type of bush bean, and three or more wild varieties of kupa.
These forest fields are always located near streams, which generally guarantee a stand of trees. Even in the savanna, where patches of forest are often few and far between, there are areas where collected plants have been replanted to form food depots.
The Kayapó once maintained an extensive system of interlacing trails linking all their vast territory. Most of these ancient trails are now abandoned, but not all, and the Kayapó are still masters of the forest and savanna and travel considerable distances.
I once traveled for five days with four Kayapó man on long-abandoned trails to an ancient village site. Although the trails were overgrown and difficult to follow, they had been used so much that in some places they were etched six inches into the hard earth. Each night we would stop at a stream in some spot flattened and hardened by years of use. The men would slip off into the forest and soon return with a variety of roots, tubers, stalks and fruits. Foods were readily acquired even on parts of the trail known to have been abandoned 40 years before.
It was nearly two months after I began my life with the Kayapó that I realized that not all collected roots, seeds and cuttings ended up in stomachs. For example, a Kayapó would find it natural to replant a portion of what he had foraged near where he defecated.

Surui Reforestation

Listen to Darrell Addison Posey on Kapayo ecosystem engineering: 
The creation of forest islands, or Apete, demonstrates to what extent the Kayapo can alter and manage ecosystems to increase biological diversity. Apete begin as small mounds of vegetation, about one to two meters round, created by ant nests in open areas in the field. Slight depressions are usually picked out because they are more likely to retain moisture. Seeds or seedlings are planted in these piles of organic material. The Apete are usually formed in August and September, during the first rains of the wet season, and then nurtured by the Indians as they pass along the savannah trails. As Apete grow, they begin to look like up-turned hats, with higher vegetation in the centre and lower herbs growing in the shaded borders. The Indians usually cut down the highest trees in the centre to create a donut-hole centre that allows the light into older Apete. Thus a full-grown Apete has an architecture that creates zones that vary in shade, light and humidity. These islands become important sources of medicinal and edible plants, as well as places of rest. Palms, which have a variety of uses, prominently figure in Apete, as do shade trees. Even vines that produce drinkable water are transplanted here. Apete look so "natural", however, that until recently scientists in fact did not recognise them as human artefacts. According to informants, of a total of 120 species inventoried in ten Apete, about 75 percent could have been planted. Such ecological engineering requires detailed knowledge of soil fertility, micro-climatic variations, and species niches, as well as the interrelationships among species that are introduced into these human-made communities.

Gary Snyder Quotes

Listen to Gary Snyder (salvaged & unsorted), the pictures come from here:
Teaching should begin with what the local forces are. You can learn a great deal of ecology and geology from your area. But to give another dimension to that, you have to consult the Indian mythology and ritual and magic of the area and try to understand why it was they saw certain figures as potent. Why do the Winnebago see the hare as potent? Also, economic use of the land by Indians is very illuminating. If you want to know what it is you would do if you were taken back rock bottom, and what you would have to do to survive in your region, then you would have to consult the first people. What did they eat? What did they make fibers of? What did they make soap out of? What did they use for medicine? What were their basic materials – economic botany in other words. They painted their bodies red? Where did they get their pigments? All of these things are right under your foot.
And even though you might never have to use them in any economic sense, it is a great extension of one’s awareness of place. You should really know what the complete natural world of your region is and know what all its interactions are and how you are interacting with it yourself. This is just part of the work of becoming who you are, where you are. 
Life is not just a diurnal property of large interesting vertebrates; it is also nocturnal, anaerobic, cannibalistic, microscopic, digestive, fermentative: cooking away in the warm dark. Life is well-maintained at four-mile ocean depth, is waiting and sustained on a frozen rock wall, is clinging and nourished in hundred-degree temperatures.
Throughout human history and prehistory, the trail was only to get you somewhere. What was important was what was off the trail. Food, roots, berries, dye plants, glue plants, poisonous plants, recreational-drug plants, squirrel nests, bird nests, everything you might think you'd need. What's way off the trail are the places you go to be alone and have a vision and your own spiritual trip, maybe with some of those recreational plants and then you come back.























On language as a wild system:

On Climax:
The communities of creatures in forests, ponds, oceans, or grasslands seem to tend toward a condition called climax, “virgin forest” - many species, old bones, lots of rotten leaves, complex energy pathways, woodpeckers living in snags, and conies harvesting tiny piles of grass. This condition has considerable stability and holds much energy in its web - energy that in simpler systems (a field of weeds just after a bulldozer) is lost back into the sky or down the drain. All of evolution may have been as much shaped by this pull toward climax as it has been by simple competition between individuals and species. If human beings have any place in this scheme it may well have to do with their most striking characteristic - a large brain, and language. And a conciousness of a peculiarly self-concious order. Our human awareness and eager poking, probing, and studying is our beginning contribution to planet-system energy-conserving; another level of climax!

Well, to put it quite simply, I think language is, to a great extent, biological. And this is not a radical point of view. In fact, it is in many ways an angle of thought that has come back into serious consideration in the world of scientific linguistics right now. So, if it's biological, if it's part of our biological nature to be able to learn language, to master complex syntax effortlessly by the age of four, then it's part of nature, just as our digestion is part of nature, our limbs are part of nature. So, yes, in that sense it is. Now, of course, language takes an enormous amount of cultural shaping, too, at some point. But the structures of it have the quality of wild systems. Wild systems are highly complex, cannot be intellectually mastered—that is to say they're too complex to master simply in intellectual or mathematical terms—and they are self-managing and self-organizing. Language is a self-organizing phenomenon. Descriptive linguistics come after the fact, an effort to describe what has already happened. So if you define the wild as self-managing, self-organizing, and self-propagating, all natural human languages are wild systems. The imagination, we can say, for similar reasons, is wild. But I would also make the argument that there is a prelinguistic level of thought. Not always, but a lot of the time. And for some people more than other people. I think there are people who think more linguistically, and some who think more visually, or perhaps kinesthetically, in some cases.
