What is the International Union for Conservation of Nature's (IUCN) Red List?

A list that classifies species based on their conservation status.

Which biomes are particularly significant for global biodiversity?

What influences biodiversity data collection?

Classification issues and lack of funding for scientific research.

What is a flagship species?

A species selected to help protect others in an area.

What are the main arguments for conservation efforts?

Aesthetic, ecological, economic, ethical, and social justifications.

What factors influence the success of conservation efforts?

Community support, adequate funding, and proper research.

What are the criteria for designing protected areas?
