Assumir that after the first year, it has reached a spread of 3 acres. Mark one of the following alternatives as a good approximate description of what will happen: O 3: The surface area covered by Japanese Stiltgrass will grow during the initial years and then reach an equilibrium at approximately 12 acres. O2: The ground in the forest will be completely covered by Japanese Stiltgrass after approximat 6 years. 1: The ground in the forest will be completely covered by Japanese Stiltgrass after approximate 40 years. 4.
