2. PRECISION SILVICULTURE
• Precision silviculture means that every variable in tree farming system such as site preparation, the number of
seedlings planted per-unit area, quality of the planting material used, control of surrounding vegetation,
fertilization etc. Precisely matched to a site’s soil conditions.
• Precision Silviculture is one, which aims at developing a Silvicultural package to improve productivity, obtain
sustainability in yield and fetch maximum profit from such laid out plantation.

3. SILVICULTURE PRACTICES IN BAMBOO
• Silvicultural system is defined as the set of silviculture procedure worked out in accordance with accepted set of
silvicultural principles by which crop constituting forest are tended, harvested and replaced by new crops of
distinctive form.

4. BAMBOO
• Bamboo are a group of tall, perennial, arborescent grasses . over 135 species of bamboos are found in India.
Bamboos are found in the west and moist regions of India. They are usually mixed with deciduous or evergreen
forests or in small almost pure patches.
 Introduction
 Local Name: Baash
 Family: Poaceae
• Natural Occurrence: It is native to warm and moist tropical and warm temperature climates .
However ,many species are found in diverse climates , from hot tropical regions to cool
mountainous regions and highland cloud forests.

5. SCIENTIFIC CLASSIFICATION
KINGDOM Plantae
CLASS Angiosperms
SUBCLASS Monocots
SUBORDER Commelinids
ORDER Poales
FAMILY Poaceae
SUBFAMILY Bambusoideae

6. GROWTH CHARACTERISTICS
Bamboos consist of woody stems known as culms which arise from woody rhizome.
Culms grow in groups or clusters known as clumps.
About 20 to 30 culms are produced every year by the larger species while this number in
smaller ones may be up to 100 or even more.
The length of culms varies from species to species. The culms of Dendrocalamus giganteus
may be up to 36m. In height while those of Arundinaria jaunsarensis may be only about 0.5
m.
The culms of moist bamboos are hollow but those of some species are solid.
Mature culms of most species may attain a girth of about 30 cm.
Bamboos grow very rapidly and a culm may put on a height growth of about 0.2m in single day.

8. LIST OF BAMBOO SPECIES
• Dendrocalamus hamiltonii
• Bambusa nutans
• Bambusa balcooa
• Bambusa bambos
• Bambusa tulda
• Dendrocalamus giganteus
• Dendrocalamus strictus
• Bambusa vulgaris
• Bambusa arundinaceae
• Dendrocalamus longispathus

9. SILVICULTURAL CHARACTERISTICS
• Light : Strong light demander
• Frost: Moderate frost tender
• Drought : Moderately drought sensitive
• Fire: Highly sensitive
• Coppice : Well
• Browsing: Highly sensitive to browsing
• Soil type: Occurs to sandy loams to loamy clayey soils.
• Root system: Rhizomes are present.
• Tree nature: Perennial grasses with woody culms from rhizomes,grows in any condition but often doesn’t grow
well on dry soils.
• Main associates: Shorea robusta, Tectona grandis, Grewia spp., Terminalia spp.

10. SILVICULTURAL SYSTEMS FOR BAMBOOS
• Cleaning and cultural operation.
• Selection cutting combined with cleaning and cultural operations.
 Felling Rule
• Bamboo needs a felling cycle of 3-4 years.
• Bamboos to be felled are marked at BH first.
• Cutting of one year and some times two year old culms are restricted.
• Certain old clumps are retained for general protection.
• Digging of rhizome is prohibited as it produces the natural regeneration.
• Bamboo should be cut at a height of 15 cm leaving at least with one node.
• Cutting is done with sharp instrument.
• Bamboo should be cut after the seed shed to encourage natural regeneration.
• Lopping of Bamboo should be avoided.

13. BAMBOO USES

14. TENDING
• As it grows faster, there is no need for weeding and cleaning. But in the first year 2-3 weeding
may be given for better growth.
• It produces uneven aged crops.

15. CONCLUSION
• Precision silviculture is a promising approach to sustainable forestry management, especially
when applied to quickly growing species such as bamboo. Precision silviculture maximizes
productivity and minimizes environmental effect by applying management strategies at a fine
scale. This is made possible by utilizing cutting-edge technology like machine learning, GIS,
and remote sensing. Precision silviculture can greatly enhance cultivation methods for quickly
growing bamboo species, resulting in higher yields, higher-quality products, and more effective
use of available resources. Silvicultural techniques can be adjusted to match the particular
requirements of bamboo stands by combining site-specific data with real-time monitoring. This
allows for the management of issues including pest infestations, nutrient shortages, and
competition. Furthermore, bamboo ecosystems in the united states could become more resilient
because to precision silviculture.
