Study Notes
Ecology and Veld Types
- Ecology is the study of how organisms interact with each other and their physical environment.
- Veld types are classified based on palatability, which is affected by temperature and rainfall.
Sweetveld
- Sweetveld is a type of veld that is palatable and occurs in areas with low rainfall and mild winters.
- The soil in sweetveld areas has a high fertility status due to minimal leaching, resulting in grasses with high nutritional value.
- Little nutrients are stored in the roots during mild winters, making the grass palatable even in winter.
- Examples of sweetveld include dry woodland and karoo.
Sourveld
- Sourveld is a type of veld that is unpalatable, particularly in winter, and occurs in areas with high rainfall and cold winters.
- The soil in sourveld areas is poor and has a low pH due to leaching over many years.
- Grasses in sourveld areas are poor in nutrients and withdraw nutrients from leaves to store in roots to survive severe winters.
- This makes the grass unpalatable.
Mixed Veld
- Mixed veld is an intermediate form between sweetveld and sourveld, with characteristics of both.
- Sweetveld grasses occur in protected areas with fertile soil, such as lower lying parts and next to rivers.
- Sourveld grasses occur in open areas in mixed veld.
