Forest Regeneration and Succession Concepts

The video explains how forests regenerate after disturbances using pioneer species like Vigilia, which thrive in sunlight and fix nitrogen. These species pave the way for secondary succession species, often spread by birds. Additionally, forests can recover through coppice shoots from tree stumps, allowing faster regeneration without relying solely on seeds.

What is the initial step in forest regeneration after a disturbance?

• Introduction of secondary species

• Growth of pioneer species

• Planting of new trees

• Removal of dead trees

Which species is known as the kerboom and acts as a pioneer in forest regeneration?

• Oak

• Pine

• Vigilia or Aboitiz

• Maple

What role do pioneer species play in the nitrogen cycle of a regenerating forest?

• They deplete nitrogen

• They release nitrogen

• They fix nitrogen

• They store nitrogen

How do seeds of secondary succession species typically arrive in a regenerating forest?

• Carried by the wind

• Brought by animals

• Planted by humans

• Deposited by birds

What is the main benefit of pioneer species creating shady spots in a regenerating forest?

• They reduce fire risk

• They prevent soil erosion

• They attract birds that bring seeds

• They increase water retention

What is the primary function of secondary succession species in forest regeneration?

• To provide shade

• To fix nitrogen

• To establish biodiversity

• To decompose organic matter

What is the process called when new shoots grow from the root system of a burnt tree?

• Seed germination

• Coppice shoot formation

• Photosynthesis

• Root expansion

Which part of the tree remains alive to allow coppice shoot formation?

• Trunk

• Leaves

• Branches

• Root system

What is a key advantage of coppice shoot formation over seed-based regeneration?

• Faster recovery

• More biodiversity

• Higher water retention

• Less sunlight required

Which method of forest regeneration is typically faster?

• Seed-based regeneration

• Neither is effective

• Coppice shoot formation

• Both are equal
