Biodiversity and Invasive Species Management

The video discusses the impact of alien species on biodiversity in the Garden National Park, focusing on how fire influences these species. It highlights the importance of controlling invasive species post-fire and the discovery of new species in the park. Effective management and follow-up measures are crucial to prevent recolonization by invasive species.

What is considered the primary threat to biodiversity in the Garden National Park?

• Alien species

• Deforestation

• Climate change

• Pollution

How many alien plant species are considered transformative in the Garden National Park?

• 5 to 10

• 10 to 15

• 15 to 20

• 20 to 25

What adaptation allows certain alien species to thrive after a fire?

• Rapid growth rate

• Seed storage in canopy

• Fire-resistant bark

• Deep root systems

What is a characteristic of black wood that makes it particularly resilient after a fire?

• It has a short lifespan

• It has a thick bark

• It grows in clusters

• It can resprout from roots

Why is it important to control alien species before they seed?

• They spread rapidly

• They become more resistant

• They deplete soil nutrients

• They attract pests

What recent discoveries have been made in the Garden National Park?

• New species of amphibians

• New species of plume moths and beetles

• New species of birds

• New species of reptiles

What phenomenon allows some plant species to reappear after being considered extinct?

• Introduction of new species

• Extreme natural events

• Human intervention

• Climate change

What is crucial for managing invasive species after a fire?

• Immediate replanting

• Introduction of predators

• Follow-up control measures

• Use of pesticides

What is a major challenge in managing large expanses of land after a fire?

• Difficulty in accessing the area

• Ensuring effective management of invasive species

• High cost of resources

• Lack of manpower

What needs to be encouraged to prevent recolonization by invasive species?

• Investment in resources and follow-up efforts

• Collaboration with international organizations

• Development of new technologies

• Public awareness campaigns
