Forestry and Management Practices

Forestry Definitions and Practices

• Forestry: The science and practice encompassing forest creation, conservation, scientific management, and resource utilization.
• Silviculture: Focuses on establishing, developing, caring for, and reproducing forest crops.

Forest Management Techniques

• Pollarding: Cutting branches above browsing height to stimulate new growth. Commonly used on willow trees in Kashmir, Hardwickia binata in Andhra Pradesh, and Grewia robusta.
• Coppicing: Cutting plants near ground level to encourage new shoot growth. Examples include willow, poplar, alder, and acacia species.
• Lopping: Cutting branches or young stems to promote new shoots. Used for Diospyros (bidi industry), various broadleaf species (fuel and fodder), and Quercus leucotrichophora (silkworm rearing). Essentially, trimming tree branches to manage size.
• Pruning: Cutting branches from the bole to improve timber quality, protect against disease, and promote tree health.
• Taungya System: A method of replanting forests where laborers cultivate crops on forest land in exchange for planting and protecting trees. Originated in Burma (Myanmar) around 1850.

Seed Production and Nursery Management

• Seed Orchards: Plantations specifically for seed production.
• Seed Production Areas/Seed Stands: Designated areas for high-quality seed production from superior trees. Seed orchards may be clonal (grafted clones) or seedling (from superior tree seeds).
• Pricking Out: Transplanting seedlings individually into nursery beds or boxes, typically when they will remain in the nursery for over a year.

Protective Plantations

• Windbreaks: Protective plantations (few rows of trees or shrubs) against strong winds, spaced 0.5 to 2.5 meters apart.
• Shelterbelts: Wider zones of trees, shrubs, and grasses planted in rows (usually perpendicular to prevailing winds) to deflect air currents, reduce wind velocity, and protect areas from desiccation.

Forest Management Operations

• Tending: General term for operations promoting forest crop well-being (e.g., weeding, cleaning, thinning, improvement felling). Excludes regeneration operations (regeneration felling, soil working, control burning).
• Felling: Removing trees individually or in small groups throughout a forest.

Forest Establishment and Classification

• Afforestation: Establishing a forest on an area that hasn't had forest vegetation for a long time.
• Reforestation: Re-establishing a forest on an area that previously had forest vegetation but was cleared.
• Reserved Forests: Areas with full protection under the Indian Forest Act or state forest acts. All activities are prohibited unless permitted.
• Protected Forests: Areas with limited protection under the Indian Forest Act or state forest acts; activities are permitted unless prohibited.
• Unclassed Forests: Forests not classified as reserved or protected, with varying ownership statuses.

Forest Measurements and Terminology

• Basal Area: Cross-sectional area of a stem at breast height; for a crop, the sum of all stem basal areas per unit area.
• Bole: The main stem of a tree.
• Breast Height: Standard height for measuring tree girth, diameter, and basal area (1.37 m in India; 1.30 m in the UK and many Commonwealth countries).
• Crown: The upper branched part of a tree above the bole.
• Dendrology: The study of tree identification and classification.
• Log: A felled and trimmed tree stem or branch section.
• Logging: The process of harvesting, sawing, and transporting trees to a sawmill.
• Pole: A young tree, between the time lower branches begin to fall and height growth slows, with marked crown expansion.
• Raft: A collection of logs, timbers, or bamboo tied together for transport by water.
• Scrub: Inferior growth of small or stunted trees and shrubs.
• Stand: A uniform aggregation of trees or plants forming a silvicultural unit.
