After abandonment, the agricultural land is exposed to sun, deprived of moisture and essential nutrients. Only those trees that can resist such harsh conditions can grow. The pine trees have the ability to grow in such conditions and their seedlings florish under sunlight in open areas. However, the seedlings are competing with environment to get foothold on land. After establishing a good growth, the patches of areas are formed among pine trees which create an moist environment of partial shade. These shady conditions are not good for the growth of pine seedlings. As a result shade tolerant hardwood trees start to invade and continue their growth relentessly.
