(a) Ten common grass and legume species of Nigerian pastures and their common and botanical names are:

1. Guinea grass (Panicum maximum)
2. Elephant grass (Pennisetum purpureum)
3. Napier grass (Pennisetum purpureum)
4. Buffalo grass (Panicum coloratum)
5. Rhodes grass (Chloris gayana)
6. Star grass (Cynodon nlemfuensis)
7. Carpet grass (Axonopus compressus)
8. Para grass (Brachiaria mutica)
9. Stylo (Stylosanthes guianensis)
10. Lablab (Lablab purpureus)

(b) Three factors affecting the distribution of pastures in Nigeria are:

1. Climate: The distribution of pastures in Nigeria is largely influenced by the climate of the region. Regions with a tropical climate, high rainfall, and moderate temperatures are more likely to have lush green pastures than regions with arid or semi-arid climates.
2. Soil type: The type and quality of soil also affect the distribution of pastures in Nigeria. Regions with fertile soils that can support the growth of grasses and legumes are more likely to have abundant pastures.
3. Grazing pressure: The level of grazing pressure in an area can affect the distribution of pastures. Overgrazing can lead to the depletion of pastures and reduce their distribution, while proper grazing management practices can lead to the sustainable use and maintenance of pastures.
