Flora
Flora encompasses all plant life in a particular region, forming the foundation of terrestrial ecosystems and serving as the primary producers in most food webs. In terraforming projects, establishing diverse and resilient plant communities is the cornerstone of creating sustainable habitable environments.
Categories of Flora
Vascular Plants
- Trees: Long-lived woody plants forming forest canopies
- Shrubs: Medium-sized woody plants for understory and transition zones
- Herbs: Non-woody flowering plants for ground cover
- Grasses: Monocotyledonous plants forming grassland ecosystems
- Ferns: Spore-bearing plants for shaded, moist environments
Non-Vascular Plants
- Mosses: Small plants forming dense mats in moist areas
- Liverworts: Simple plants in wet habitats
- Hornworts: Primitive plants with photosynthetic structures
- Algae: Aquatic and semi-aquatic primary producers
