Final answer:
a. Urban areas have limited potential for reforestation, while agricultural lands, marginal lands, and protected areas have varying levels of potential.
Step-by-step explanation:
When considering the potential for reforestation and afforestation in Maryland, several types of land areas have different levels of potential. a. Urban areas, such as cities, have limited potential for reforestation due to high population density and lack of available land.
Agricultural lands, on the other hand, have moderate potential as they can be converted into agroforestry systems or tree plantations. Marginal lands, which may have degraded soil or low agricultural productivity, have higher potential for reforestation.
Finally, protected areas, such as national parks and nature reserves, have the highest potential for reforestation due to their conservation focus.
