ANIM2501 Lecture Notes - Lecture 3: Human Factors And Ergonomics, Carrying Capacity
Ecology of Native Pastures
Quiz thingy:
A. Predominantly cattle
B. Cattle and sheep
C. Not predominantly cattle?
D. Good for tourist but not cattle. Infertile soil and not productive and palatability.
E. Not good for cattle
Quiz thingy:
A. 26-30 million
B. Correct
C. Improved pastures support about 30% of livestock
D. Asian market
*Ecology shows adaptations for plants and where you'll find those plants.
Factors that dictate plant growth
1. Rainfall
2. Soil
3. Temperature (Northern region to hot for rye grass)
4. Human factor (e.g. How landholders manage their pastures, change in species composition.)
Natural factors
1. Soil
2. Climate
3. Plant adaptation
Man related influences
1. Grazing
2. Animal species influence
3. Burning
Soil Type
- Soil provides the nutrients and stores the moisture. Type of soil dictates how much rainfall is
captured and supplied to plant.
- Key soil attributes affecting productivity and ecology:
- A. Soil Nutrient fertility

Document Summary
Quiz thingy: predominantly cattle, cattle and sheep, not predominantly cattle, good for tourist but not cattle. Infertile soil and not productive and palatability: not good for cattle. Improved pastures support about 30% of livestock: asian market. *ecology shows adaptations for plants and where you"ll find those plants. Factors that dictate plant growth: rainfall, soil, temperature (northern region to hot for rye grass, human factor (e. g. how landholders manage their pastures, change in species composition. ) Man related influences: grazing, animal species influence, burning.
