Question

Quizplus · Accepted Answer

Fires and grazing by large mammals help limit the growth of woody plants in temperate grasslands. Fires prevent the establishment of woody vegetation, and grazing by large mammals such as bison and elk keeps woody plants from becoming dominant. Nutrient-poor soil, high insect diversity, large numbers of cacti, and mild winters with low annual precipitation may also affect plant growth, but they do not specifically limit the growth of woody plants in temperate grasslands.
