Final answer:
Aika's main job responsibilities likely include spreading pesticides to address insect pests, implementing containment and population control strategies for the pine trees, and possibly engaging in restoration efforts to recover native ecosystems after controlling pine invasions.
Step-by-step explanation:
Aika manages a woodlot that grows pine trees for the construction industry. One of Aika’s main job responsibilities is most likely c. to spread pesticides to kill harmful insects. Pine trees can be affected by pine bark beetles which, due to climate change, are thriving in milder winters and longer summers, leading to significant tree mortality rates. Aika must also ensure that containment and population control measures are in place to prevent the spread of pine trees outside the plantation areas.
This includes the early detection and removal of trees colonizing the surroundings to avoid invasions. Additionally, Aika needs to be mindful of the environmental impact of pine trees and engage in restoration efforts when necessary to ensure the recovery of the native ecosystem after controlling pine invasions.
