Teak is the common name for the tropical tree and wood of Tectona grandis. This popular investment tree is native to south and southeast Asia, but is also planted as an introduced species in Africa, Central and South America. Teak is grown in plantation settings, because its fine wood has a large market and demand. The teak tree can be a very good investment, with high returns, but it may take as much as 30 years for plantation teak trees to be big enough to sell. The yellowish brown wood is used for fine furniture, outdoor furniture, boat decks and other articles, where weather endurance is required. The wood is mostly termite and insect resistant. Other popular uses include wooden bowls, cutting boards, arts and crafts, indoor flooring, veneers and finishing wood. There is an environmental concern, because of past reckless logging of old growth teak, though the majority of teak wood now comes from plantations.
The market for teak wood is always good, provided one is selling mature lumber from larger trees (25 to 30 years). The market for lumber from small teak trees is very limited (12 to 20 years) and does not fetch anywhere near the prices paid for large, mature logs and sawn lumber. Many firms offer investments in teak plantations, and some of them are reliable business partners. However, while teak is a high return commodity, it is not a quick return investment. This article will briefly address some of the issues that teak investors should consider, and contrast those considerations with other possibilities.
Teak trees need relatively good soil in which to grow. They do not do well in poor or infertile soils. If a planter can match the soil and rain conditions found in Burma (Myanmar), they will have excellent results. Similar conditions are known to exist in Costa Rica, Panama and parts of Colombia. The downside of this fact is that other, faster growing trees or crops can be grown in places set aside for teak trees, which sometimes puts pressure on teak plantations that require many years to produce mature trees. It is not uncommon for teak plantation owners to cut down their immature teak trees to make way for other agricultural or housing projects that offer a quicker cash flow solution to the land owner.
Tectona grandis does not provide any other cash flow while it is growing. There is a limited use of the leaves in south India and Indonesia as a wrap for steamed preparations, but that is of no commercial value. Many other species of tropical trees have fruits, nuts, honey or resins that can be sold while the trees are growing. Experience in Central America has shown that teak is not that environmentally friendly in regions where it is an introduced species. A common observation by visitors to teak plantations in the Americas is that they are devoid of bird, animal or insect life. Additional issues are the fact that teak trees need good soils that could be used for food production, and the fact that teak is generally planted in monocultures due to the high cost of good land.
From an investment perspective the long time to maturity required by teak trees needs to be considered when investing in their cultivation. Best intentions do not resolve practical problems. For example, will the planter with whom one invested still be alive in 25 to 30 years? Does the company operating the plantation have a continuity plan which the investor can trust? What happens to the trees in the event of a bankruptcy or other form of liquidation? What happens if land prices increase exponentially mid-way through the growth cycle, putting pressure on the land owner? Even if the trees are somehow protected, who will see to future fertilizations, pruning, culling, fire breaks and other maintenance if the original company or plantation owner is no longer active?
It is also worth thinking in terms of insurance. The longer the growth period for a tree, the more exposure one has to potential natural disasters like fire, pests, floods, droughts or diseases. This risk factor is obviously much smaller with fast-growing tree species that mature in 10 years versus 30 years. As a teak investor one should definitely inquire as to a company’s or plantation owner’s Plan B or insurance. For example, Amazonia Reforestation in Colombia, which does not cultivate teak, has a self-insurance plan that involves planting twice the number of tropical trees for which it has financial obligations, as well as planting a variety of species to reduce risks.
This does not mean one should not invest in teak, but rather that it is important to do so with open eyes and a full understanding of the long time commitment required by successful teak plantations. Diversifying so that one has holdings in other, faster growing tropical tree species, as well as teak, makes a lot of sense. Teak is not the only game in town, so having a tropical tree investment strategy that includes other species is a good thing. Teak investments are usually more costly than other tree species, because of the long maintenance period involved, but the payoff is not something one will regret. As with other tropical tree species, it is correct to say that teak trees can be low to medium risk but high return.

This year Amazonia Reforestation planted 50 hectares or 124 acres of Caribbean Pine or Pinus caribaea, a member of the Pinaceae family. The tree grows well in areas from sea level to 700 m or 2,300 feet, with ample rainfall between 2000 to 3000 mm (78 to 118 inches) per annum. Since Amazonia Reforestation works in the Orinoco River basin of Vichada, Colombia, it meets those criteria readily, as its plantations average 60 m (197 feet) above sea level with annual rainfall around 2,400 mm (95 inches). Pinus caribaea likes sandy, well drained soils with some gravel content, tolerates pH between 5.0 to 5.5 and temperatures ranging from 25 to 38 degrees centigrade (77 to 100 Fahrenheit), all normal conditions in Vichada.
In some ways Pinus caribaea resembles pines with which people from North America or Europe may be familiar, such as evergreen needles and cones. However, that is where the similarity ends, as Caribbean Pine is a fast growing (15 to 20 years to maturity) softwood tree with wood that is harder than many varieties of maple. This tropical tree has a mostly well-formed and straight trunk that culminates in a pyramidal crown at its top. The tree grows to be 30 to 35 meters (98 to 115 feet) in height, with a trunk that measures from 50 to 100 cm (20 to 40 inches) in diameter, depending on local conditions. The basic density of Pinus caribaea is expressed as being 586 kilograms per cubic meter of green volume, but with a natural hardness that makes the tree suitable for flooring and other uses. The heartwood is considered termite resistant. These factors have made Caribbean Pine a popular plantation species, with an attractive grain, that is profitable, sequesters carbon, and is internationally recognized.
Amazonia Reforestation uses certified seeds from Venezuela, where Caribbean Pine is grown in similar conditions to Vichada. Seeds from Honduras and Guatemala have proven not to be suitable for use in the Orinoco River basin, probably because of their origin in higher, cooler elevations. Trees have both male and female flowers and cones, though some trees may be only male or female. Seed germination is usually easy in managed conditions. Local conditions in Vichada have led Amazonia Reforestation to employ a slightly different process in its tree nurseries, with seedlings being exposed to full sunlight to minimize future shock when transplanted to the field. Soil preparation is as usual important, with plowing to a depth of 75 cm (30 inches) and fertilization using special forestry mixes containing nitrogen. Seedlings are planted in the field when they are only 8 to 10 cm (3 to 4 inches) tall, but this allows the seedling to quickly strike deep roots for better and faster future growth. Seedlings that are planted when they are 20 cm (6 to 8 inches) or taller often have problems, because their roots will start to grow upwards inside the planting bag, causing failure once they are in the field. Planting occurs in grids with trees spaced 2.8 to 3 meters (9 to 10 feet) apart.
Revenue can be generated early (15 years) when the trees are sold for pulpwood, thanks to the wood’s long tracheids. Besides paper, the pulp can be used for fiberboard, particleboard and chipboard. Opinions differ on its usefulness for furniture, but the fact is that toys, moldings, floor boards and other uses are common. The wood has a high resin content, which may affect gluing and finishing, but on the plus side the trees can be tapped from age 10 years on, with daily harvests of oleoresins, used for turpentine and gum. The oil also finds use in medicinal applications, and the pine nuts are a popular food source in many countries. On the service side, Pinus caribaea has proven itself invaluable for clothing heavily eroded lands containing acidic soils with a tree cover. As with many plantation species, Caribbean Pine is a valuable tropical tree popular with wood growers and profitable for plantation investors.

1. For lumber. Most people realize that if plantation wood is not available, then lumber will be cut from existing natural rain forest. It is worth repeating that it is better to have one’s coffee table made out of plantation wood, and not out of old growth tropical forest.
2. For profit. If afforestation and reforestation projects are not profitable, they are not financially sustainable. The fuzzy logic of many NGO’s on this issue is proven wrong by the reality on the ground. Humans need lumber resources for furniture, construction, boat building, farming, renewable energy and numerous other applications. Simply planting trees and then expecting them not to face the same problems forests have faced in the past is ridiculous. This means that profitable plantations can become the buffer that allows natural reserves and parks to protect biodiversity and natural forests. Profit is also boosted by demand, as humans give rabbits a run for procreativity. Don’t believe it? China now has more than 1.3 billion people, with India snapping at China’s heels, and with all of those people needing building materials, furniture, wood products, paper and fuel.
3. For biodiversity. Green companies like Amazonia Reforestation have programs to collect seeds and propagate native tree species that have been recklessly logged in the past. This is a challenging and expensive process, as there is often little information on germination, planting times, or even when or how to collect seeds. Propagation is challenged by the preference of many tropical trees to grow in social settings, in low-lying areas, or in areas subject to inundation. These factors make soil preparation, fertilization and forest management difficult. The founders of Amazonia Reforestation, members of the IUCN`s World Commission on Protected Areas, have created a natural reserve for this purpose, as an additional means of preserving biodiversity, and to inspire others to follow their lead.
4. For expanded wildlife habitat. Many animals are niche specific. This means that if native tree species are decimated, it has a direct impact on biodiversity and on the survival of many species of wildlife. By planting native tree species, responsible companies can expand wildlife habitat, while still providing lumber resources for human use. Amazonia Reforestation does this in both its natural reserve and in its plantation areas.
5. For carbon sequestration. It is scientific fact that tropical trees are very effective at carbon sequestration. Each fast growing tropical plantation tree sequesters as much as 50 lbs or 22.6 kg of carbon a year. Well over 50% of their woody biomass is carbon. Planting tropical trees is a major method of dealing with atmospheric carbon, which has gone from 350 ppm in 1985 to 393 ppm in April 2011 (Mauna Loa Observatory, Hawaii). CO2 Tropical Trees promotes that fast growing tropical trees are most effective at carbon sequestration within the first 10 years of their lives, a fact that jives well with human lumber requirements, leaving the carbon trapped in the wood for decades after harvest.
6. For cloud seeding. The natural process of transpiration by forests creates cloud in the atmosphere that in turn bounces solar rays back into space, thereby cooling the Earth. Deforestation causes the opposite effect, including desertification of the planet and a hotter climate. An investment in tropical trees therefore offers up a double whammy against climate change and global warming thanks to cloud seeding and carbon capture.
7. For land reclamation. Many plantation species do well in infertile tropical soils, fixing nitrogen and depositing carbon in the soil, building up the soil so that after a harvest other more exotic and delicate species can be planted. Tropical tree planters like Amazonia Reforestation and CO2 Tropical Trees choose Acacia mangium, Azadirachta indica (Neem) and other legume family trees for nitrogen fixing, Eucalyptus pellita for water retention and wind breaks, Pinus caribaea, Caraipa llanorum (Saladillo) and Anacardium occidentale (cashew ) for acidic soils, to name a few. All of these tropical trees are planted with the long term goal of building up the soil, removing pollutants from the air, preventing erosion and allowing improved use of the soil in the future.
8. For socio-economic development. Tropical trees provide local communities with more than just some jobs in the lumber industry. They also allow for the creation of spin-off industries in developing countries, including apiculture, tannins and dyes, insecticides and fungicides, repellents and toxins, fruits and nuts, medicinal and naturopathic products, arts and crafts, foods and liquors, gums and adhesives, resins and varnishes, latex and oils, boat building and musical instruments, eco-tourism and adventure tourism, fuel and charcoal, animal fodder and protection, as well as agroforestry, permaculture and analog forestry opportunities. More people around the globe with disposable incomes helps to increase demand for tropical hardwoods.
9. For renewable energy. Many countries now require that power generation involve a significant percentage of alternative energy. Solar, wind and water energy are not always practical or available. That leaves biomass as an additional option. Biomass can be almost carbon neutral, as it only releases what it absorbed from the atmosphere in the first place, which is better than the steady addition of atmospheric CO2 caused by hydrocarbons like petroleum and coal. Many fast growing plantation species have high calorific values, which when compressed into wood pellets and similar products can rival coal for kcal (kilocalorie) output.
10. For afforestation and reforestation. At present, people worldwide are only planting 10% of the trees we are harvesting, burning or removing on an annual basis. This is clearly not sustainable, as evidenced by climate change, desertification and loss of biodiversity. This in turn has a direct impact on the human spirit, on our health and on the survival of our planet. Green investors plant trees for a better world and because it is low risk but high return.

Some people think that planting trees simply involves sticking them in the ground and they will grow, without more. Many are astonished to learn that it costs approximately $1 million dollars to plant 1,000 hectares (2,470 acres) of tropical trees properly. The reality is that there are a lot of steps that need to be taken for success. This article sets out 10 of the early steps we take at Amazonia Reforestation:
- One needs to have a good source of seeds. Seeds with bad genetics or seeds taken from the wrong climate will often not grow or produce poor results and gimped trees.
- Good soil preparation is extremely important. We plough the soil to a depth of 75 cm and sometimes as deep as 90 cm, depending on the species. That is because tropical trees set deep roots in the soil. Good soil preparation allows the trees to grow faster, because then they are not struggling to break through compacted soil. Deep roots prevent losses due to high winds or wet swampy soil.
- Most tropical soils are infertile, which means we need to provide the trees with proper nutrition if we want fast and good results. At La Pedregoza we use a special mix of forestry fertilizer that contains nothing but elements, no chemicals and no inert matter. This allows the trees to grow quickly, after which they become self-sufficient using photo-synthesis, carbon capture and recycling to grow. Virtually all rain forest trees are perfect recycling systems, which is why soils in Amazon deforestation areas are often poor after the trees are removed.
- Our fertilizer mix also contains calcium or lime. The tree doesn't need the lime directly, but it is required in order to balance the PH levels of tropical soils, which are often acidic due to thousands of years of pounding tropical rains, that leach the soil, leaving it acidic. The lime also softens the soil, which might otherwise bake into a cement-like hardness, allowing the roots of the seedling to quickly spread in the soil. Most tropical trees prefer a balanced PH soil.
- We establish good fire breaks all around and throughout the plantation. This prevents grass fires and forest fires from damaging the new trees or from spreading. Once the trees become more than 3 years of age most of them act as natural fire breaks against grass fires, because hardwood trees do not burn as easily as softwood trees.

January 24, 2011 Press Release
Reserva Natural La Pedregoza, is located some 57 km from the Orinoco port city of Puerto Carreño in the eastern Colombian department or state of Vichada. The reserve is some 10 square kilometers in size and features 3 old growth inundation and gallery forests along the banks of the Rio el Bita river.
Dexter Dombro , a former Alberta lawyer, his wife Dr. Kochurani Dombro , an Edmonton dentist, and their eldest son Dilmun Dombro , a science student, have been engaged for the past 3 years in tropical tree afforestation and reforestation efforts in the Orinoco River basin of Colombia. “When the opportunity presented itself to conserve and protect this very special area, we put our money where our mouths are!” said Dexter Dombro, “It seemed completely self-evident that this was the right thing to do.”
Asociación Red Colombiano de Reservas Naturales de la Sociedad Civil). Lourdes Peñuela Recio, V.P. of the Green Horizon Foundation (Fundación Horizonte Verde) of Colombia has welcomed this natural reserve among protected areas in what is called the Orinoco node.
Reserva Natural La Pedregoza is the conservation and preservation of Orinoco River basin flora and fauna. Colombia is estimated to have up to 8% of the planet’s biodiversity within its borders, making it hugely important. The natural reserve helps protect that biodiversity with three key programs: 1. the collection, germination and propagation of native tree species, many of which were recklessly logged in the past, 2. a dedicated large river turtle rescue effort with an endangered river turtle egg hatchery and release program, and 3. the construction of an Interpretive Centre to educate locals and international visitors alike on the importance of the inundation and gallery forests in the Orinoco River basin.
Fundación Omacha), stated: “La Pedregoza is important, because it adds to the protected corridor for endangered wildlife travelling to and from the El Tuparro National Park (Parque Nacional Natural El Tuparro). In addition, their native tree program will help expand habitat for endangered wildlife.” Dr. Debra Davidson of the University of Alberta’s Faculty of Agricultural, Life and Environmental Sciences has visited Reserva Natural La Pedregoza and was one of the instigators for the U of A to sign a Memorandum of Understanding (MOU) with the Dombro family for U of A researchers to use the natural reserve as a research area.

Plantation owners often make lists of the benefits, uses and advantages of planting certain species of tropical trees. More often than not the list of benefits vastly exceeds the perceived negatives. It is with that in mind that this list of Jatropha curcas benefits and uses has been adapted from a Brazilian plantation by Amazonia Reforestation in Colombia, together with the addition of some extra comments. This is a typical example of why tropical trees hold such promise. Hopefully it will address some of the questions people may have about adopting this tree for large scale biodiesel and renewable energy production.
- Jatropha curcas is a perennial plant, meaning that it can live for many decades and does not need to be replanted on an annual basis. This makes for economic efficiency.
- This tree can survive in infertile and marginal soils and can be used for land reclamation, including in near desert-like conditions, while improving soil fertility. This means that Jatropha curcas survives in soils that are not suited to food production.
- In contrast to African oil palms, Jatropha curcas is a social plant that does well with other species, making it suitable for agroforestry, analog forestry and permaculture cultivation, without affecting its own oil production.

- The primary product from Jatropha curcas is oil ideally suited to bio-diesel production, at a fraction of the cost of diesel fuel from non-renewable sources.
- The mulch or cake left over after oil extraction from the fruits is rich in nitrogen, phosphorus and potassium, making it an excellent fertilizer.
- The mulch or cake can be readily used as compost and substratum.
- The mulch or cake can also be placed in bio-digestion tanks, producing a gas that can be used to generate heat or electricity.
- Planting Jatropha curcas can reclaim and upgrade degraded soils.
- The first harvest of oil seed fruits can occur as early as 180 days after planting.
- Jatropha curcas is highly resistant to plagues, diseases, pests and fungi, eliminating the need for costly pesticides and the environmental problems they entail.
- Harvest times in dry areas can be regulated by having a fixed irrigation schedule for the trees.
- Because of its deep roots, irrigation need only occur once every 20 or so days in a managed setting, though that is not relevant in areas with high rainfall.
- Six months after planting, Jatropha curcas becomes resistant to attacks by ants and termites.
- The tree can be co-planted by market garden operations for pest control.

- The bulk oil of the Jatropha curcas tree can render over 94% esters, a chemical compound used by industry in numerous processes.
- This tree can be effective for erosion control, because of its deep roots, quick growth and minimal requirements.
- Planting Jatropha curcas helps to stop desertification of the planet in poor and marginal soil zones.
- Jatropha curcas can tolerate brackish water, an important planting issue in many marginal areas.
- The oil of this tree can be used in the manufacture of stains, tints and varnishes.
- The tree’s oil can be used as a purgative or contraceptive remedy, though caution is in order due to its highly toxic nature.
- Jatropha curcas will kill a toxic weed known as Tiririca (Cyperus rotundus), which kills other plants around it.
- The gas produced from the anaerobic fermentation of Jatropha curcas is a recognized source of heat.
- The methane gas produced by the mulch or cake can be used to operate electrical generating equipment.
