While at times a barrier to settlement, the Shield has also yielded great resources, including </span>minerals<span>, </span>coniferous forests<span> and the capacity for</span>hydroelectric<span> developments.</span>
Trees serve as a natural force to prevent erosion and hold soil together during rainfall and other periods of weather that might impact the integrity of the soil.
