Final answer:
Plants favored in high-stress and low-disturbance environments, such as the tundra, include low-growing plants like lichens, grasses, and shrub willows. Management practices like controlled burns and grazing reduction play a significant role in maintaining native flora and preventing weed invasion.
Step-by-step explanation:
Plants that are favored in high-stress and low-disturbance environments tend to be those that can withstand harsh conditions without needing frequent disturbances to thrive. In ecosystems characterized by such conditions, like the tundra, low-growing plants such as lichens, grasses, and shrub willows commonly dominate.
In areas of changed fire regimes or herbivory, such as the savannas in Queensland, Australia, woody plant encroachment has increased due to cattle grazing and altered fire patterns. However, the restoration of native plant communities can sometimes be achieved with management strategies like reducing herbivory and applying consistent controlled burns.
