Final answer:
The statement that in pastoralist societies that practice transhumance only certain individuals migrate with herds is true. Transhumant pastoralists engage in seasonal migration patterns and maintain a smaller group to migrate with livestock, while others stay at permanent settlements. This form of pastoralism is sustainable and relies on intricate knowledge of the environment and herding.
Step-by-step explanation:
The statement, "Pastoralist societies who practice transhumance means that certain individuals, rather than the whole group, migrate with herds," is true. Transhumant pastoralism involves a seasonal pattern of migration where mostly a smaller group within the society migrates with the herds to different pastures during various times of the year, while others may remain in permanent settlements, participating in activities such as farming or tending to the community.
Transhumant pastoralists have patterned movements, unlike nomadic pastoralists who move unpredictably based on the availability of resources. These pastoral societies rely heavily on their animals for a variety of trade commodities such as meat, leather, and wool, and they have developed intricate knowledge about the environment to sustainably manage their herds and rangelands.
