BACKGROUND

[0004] Bamboo fiber has the ability to transform the timber industry and reverse the current trend of global deforestation. Maximizing bamboo plant yield is critical for the industrialization of bamboo as a commercial crop. Bamboo has traditionally been grown as a crop in China, through a small holder farmer model, where each farmer grows a few hectares and harvests the bamboo at a low intensity. One of the limiting factors in the commercial production of bamboo and the utilization of natural bamboo forests is that the current harvesting methods are manually intensive as the bamboo is harvested by manual selective cutting of individual culms. Attempts to harvest bamboo plantations using complete clear cutting of large areas plantations have proved unsustainable, suggesting that mechanical harvesting of bamboo was not feasible.

[0005] There is a need for bamboo plantations and for methods of bamboo harvesting that allow for sustainable and commercial bamboo production. SUMMARY OF THE INVENTION

In some embodiments, the method and plantation described herein allows for sustainable mechanical harvesting of bamboo. Bamboo as a Sustainable Fiber

[0032] Bamboo fiber has the ability to transform the timber industry and reverse the current trend of global deforestation. Bamboo fiber, woven, or in laminated form, can be used for plywood, composites and veneers. With a relatively long fiber length its pulp can also be used for a range of paper products, from sanitary paper, to copy paper to packaging. It can also be fed into the dissolving pulp industry with little change to machinery, and be used to replace cellulosic pulp with a yarn that exhibits a range of superior properties.

Bamboo also has a calorific value equivalent to most woods, allowing it to provide renewable and distributed energy across all levels of processing, from simple charcoal to gasification.

[0033] Bamboo's advantages are multidimensional but focus around the grass's ability to produce high volumes of fiber per unit area, even when grown on degraded land.

Furthermore, bamboo fiber can be substituted in a diverse range of products, including, but not limited to paper, plywood, MDF board, textiles, and bioenergy.

[0034] Ecologically, bamboo has many unique attributes that enable it to have the potential to be one of the most sustainable sources of fiber or biomass on the planet. Bamboo can reverse land degradation, restore canopy cover and maintain soil productivity, water tables and carbon cycles.

[0035] One of the limiting factors in the commercial production of bamboo is that the current harvesting methods are costly due to being manually intensive, as the bamboo is harvested by manual selective cutting of individual culms. Attempts to harvest bamboo plantations using clear cutting of individual plants or large areas of plantations have proved unsustainable, suggesting that mechanical harvesting of bamboo was not feasible. Described herein, is a method of harvesting bamboo that enables bamboo to be an economically viable crop.

Bamboo

[0036] Bamboo is a plant in the grass family Poaceae. Individual bamboo shoots emerge from the ground and grow to their full height in a single growing season. During the growing season, each new shoot grows vertically into a culm. Branching out does not occur until the majority of the mature height is reached, then branches can extend from nodes and leafing out occurs. Over time the pulpy wall of each culm slowly hardens into a fully mature culm. [0037] Some bamboo species exhibit a monopodial growth pattern. Monopodial bamboo species are also called running bamboos. Modopodial bamboo species have a underground root and rhizome system that spreads laterally. Individual plants merge into each other with no above ground distinction of where a single plant ends and the next plant begins.

Individual culms emerge from the ground at random.

[0038] In some embodiments, the monopodial bamboo plant belongs to the genus Acidosasa sp., Arundinaria sp., Bashania sp., Chimonobambusa sp., Indocalamus sp., Pleioblastus sp., Phyllostachys sp., Sasa sp., Schizostachym sp., or Semiarundinaria sp..

[0039] Some bamboo species exhibit a sympodial growth pattern. Sympodial bamboo species are also called clumping bamboos. Sympodial bamboo species have a underground root and rhizome system maintained within a relatively compact area. New culms emerge from this central system without significant lateral spread, and each bamboo plant or clump grows in an area that can be distinguished from a neighboring plant or clump.

[0040] In one embodiment, sympodial bamboo species belong to the genus Bambusa sp., Cephalostachym sp., Chusquea sp., Dendrocalamus sp., Dinochloa sp., Fargesia sp., Gigantochloa sp., Guadua sp., Melocalamus sp., Oxytenanthera sp., Schizostachyum sp., Thamnocalamus sp., Thyrostachys sp., or Yushania sp. In some embodiments, the sympodial bamboo is Bambusa vulgaris, Bambusa balcooa, Bambusa blumeana, Bambusa polymorpha, Bambusa textilis, Cephalostachyum pergracile, Dendrocalamus asper, Dendrocalamus barbatus, Dendrocalamus giganteus, Dendrocalamus membranaceus cv grandis,

Dendrocalamus strictus, Dendrocalamus sinicus, Guadua aculeata, Guadua amplexifolia, Guadua angustifolia, or Oxytenanthera abyssinica. In certain aspects, the invention relates to a bamboo plantation or to a naturally occurring bamboo forest, or bamboo stand. Naturally occurring bamboo forests or stands, and bamboo plantations can comprise native or naturalized species of bamboo. The availability of a native species of high commercial value is a factor taken into consideration for a bamboo plantation. Where no suitable native species occurs, bamboo species can be selected by their ability to meet the goals of the proposed project and area.

[0041] As with trees, each species of bamboo is unique, and has properties suitable for specific end uses. Sugar content, silica content, wall thickness, fiber length, fiber density can vary between bamboo species. [0042] Bamboo requires 5 to 7 years to reach maturity. In some embodiments, the bamboo plants of the invention should be grown for at least 5 years prior to the first harvest. In some embodiments, the bamboo plantation, bamboo forest, or bamboo stand of the invention should be at least 5 years old.

Bamboo Plantations, Bamboo Forests, and Bamboo Stands and Methods of Harvesting Same

[0043] Commercial production of bamboo can depend on maximizing yield and mechanizing harvesting methods. One advantage of bamboo is that once a bamboo plant is mature harvesting the plant in the correct manner can stimulate rapid regrowth without requiring any replanting. This results in high yields of biomass per unit area of land.

However, typically bamboo farming is manually intensive and therefore costly as it requires selective cutting of individual culms from a plant. Attempts to harvest bamboo by

mechanical non-selective clear cutting have failed and the long term yield of the bamboo plantation, bamboo forest, or bamboo stand is not sustained. Without being bound by theory, the failure of clear cutting is due to the fact that there is no leafy material left. This leafy material is required for photosynthesis and the production of energy for the plant. Once the leafy material is removed, the plant must rely on its underground reserves, which is not sustainable over time.

[0044] Described herein is a bamboo plantation, bamboo forest, or bamboo stand that significantly reduces harvesting costs, while maintaining annual productivity, high and sustained yields, as well as the ecosystem and environmental benefits of bamboo.

[0045] Also, described herein is a method of harvesting bamboo that significantly reduces harvesting costs, while maintaining annual productivity, high and sustained yields and the ecosystem and environmental benefits of bamboo.

[0046] In certain aspects, the method of harvesting described herein can be used to harvest commercial bamboo plantations, or naturally occurring bamboo forests and stands. In some embodiments, the harvested bamboo is used for the production of a high yielding fiber for the pulp and paper industry.

[0047] Monopodial Bamboo Plantations, Bamboo Forests, and Bamboo Stands and Methods of Harvesting Same [0048] In certain aspects, the invention relates to strip harvesting of monopodial bamboo culms. As described herein, strip harvesting allows the underground root system of the plant to remain intact and maintains sufficient leafy material for the plant to continue to produce sufficient food for continued uninhibited growth. The harvesting described herein allows for the clearing of all bamboo culms within a certain strip. Completely clearing a linear strip of bamboo allows for ease of removal of harvested material from the planted area. In some embodiments, the bamboo culms are manually harvested. In some embodiments, the bamboo culms are mechanically harvested.

[0049] In certain aspects, the invention relates to a bamboo plantation, bamboo forest, or bamboo stand, comprising monopodial bamboo plants, wherein bamboo culms within non- adjacent strips are harvested, wherein the non-adjacent strips are separated from each other by at least 2 strips and the strips are at least 1 meter wide.

[0050] In certain aspects, the invention provides a method of harvesting monopodial bamboo plants, the method comprising harvesting bamboo culms from within non-adjacent strips wherein the non-adjacent strips are separated from each other by at least 2 strips and the strips are at least 1 meter wide. In some embodiments, the bamboo plants are growing in a bamboo plantation. In another embodiment, the bamboo plants are growing in a naturally occurring bamboo forest or bamboo stand.

[0051] In certain aspects, the invention provides a method of harvesting a monopodial bamboo plantation, forest, or stand comprising: (a) dividing the monopodial bamboo plantation, forest, or stand into at least 1 meter wide strips; and (b) harvesting bamboo culms within non-adjacent strips, wherein the non-adjacent strips are separated from each other by at least 2 strips.

Figure 1 shows an embodiment of a monopodial bamboo plantation, each embodiment comprising repeating sets of three strips of bamboo plants. [0053] In some embodiments, the bamboo culms within non-adjacent strips are harvested once every 3 to 5 years. Therefore, in some embodiments, one third to one fifth of the plantation, forest, or stand is harvested every year. In some embodiments, the bamboo culms within non-adjacent strips are harvested once every 3 years. In some embodiments, the bamboo culms within non-adjacent strips are harvested once every 4 years. In some embodiments, the bamboo culms within non-adjacent strips are harvested once every 5 years. Figures 2-4 shows different embodiments of a monopodial bamboo plantation, forest, or stand.

[0054] The strip harvesting described herein, can be used to harvest the bamboo culms of a bamboo plantation or to harvest bamboo culms of a naturally occurring bamboo forest, or bamboo stand. Bamboo plantations, or naturally occurring bamboo forests or stands can be marked or divided into strips and harvested as described herein.

[0055] In some embodiments, the non-adjacent strips are separated from each other by 2 strips and the bamboo culms within non-adjacent strips are harvested once every 3 years. In some embodiments, every third strip is harvested on a 3 year cycle. For example, a first set of strips separated from each other by 2 strips are harvested in year 1.

In some embodiments, the third set of strips are adjacent to the first set of strips and the second set of strips. In some embodiments, the strips are harvested every 3 years. For example, after year 3, the first set of strips are harvested again in year 4, the second set of strips are harvested again in year 5, and the third set of strips are harvested again in year 6. In some embodiments, the strips can be harvested on a cycle longer than 3 years, therefore, there may be years when no strips are harvested.

[0056] In some embodiments, the non-adjacent strips are separated from each other by 3 strips and the bamboo culms within non-adjacent strips are harvested once every 4 years. In some embodiments, every fourth strip is harvested on a 4 year cycle. For example, a first set of strips separated from each other by 3 strips are harvested in year 1. In year 2, a second set of strips separated from each other by 3 strips are harvested. In year 3, a third set of strips separated from each other by 3 strips are harvested.

In other embodiments, the harvested strips are adjacent to a strip that was harvested in the previous year. In some embodiments, the strips are harvested every 4 years. For example, after year 4, the first set of strips are harvested again in year 5, the second set of strips are harvested again in year 6, the third set of strips are harvested again in year 7, and the fourth set of strips are harvested again in year 8. In some embodiments, the strips can be harvested on a cycle longer than 4 years, therefore, there may be years when no strips are harvested.

[0057] In some embodiments, the non-adjacent strips are separated from each other by 4 strips and the bamboo culms within non-adjacent strips are harvested once every 5 years.
