Introduction to Forestry

These flashcards cover key concepts from the lecture on forestry, including definitions, functions, classifications, and components relevant to trees and forest management.

What is the definition of Forestry?

Forestry is the science, art, business, and practice of conserving, developing, managing, and protecting the forest.

What is a tree?

A tree is a woody perennial plant that usually survives for many years, typically has a single main stem (trunk), a defined crown, and reaches a height of at least 4.5m (15ft).

What are the main functions of leaves in trees?

Leaves produce food for the plant, help filter dust and particles from the air, and cool the plant through the loss of water by evaporation.

Define a forester.

A forester is a professional and highly trained technical person whose main concern is the proper management, conservation, and development of the forest.

What are the components of a tree's trunk?

The trunk consists of the cambium (growth layer), sapwood (xylem), heartwood, inner bark (phloem), and outer bark.

What is the role of roots in a tree?

Roots anchor the tree to the soil, absorb nutrients and water, provide support, and help prevent soil erosion.

What are the layers of a forest?

The layers of a forest include the forest canopy (upper layer formed by tallest trees), understory (middle layer where shorter trees and shrubs grow), and forest floor (the ground layer where seedlings and tree roots are found).

What is a mangrove forest?

A mangrove forest is located in tidal flats along the seacoasts, typically where water is moderately salty.

What are the two main types of forest classification based on origin?

The two main types of forest classification based on origin are high forest (developed from seeds) and coppice forest (reproduces vegetatively by sprouts or suckers).

What are macronutrients and micronutrients?

Macronutrients are substances required in large amounts by living organisms (e.g., N, K, Ca), while micronutrients are required in small amounts (e.g., C, Fe, B).
