Since native tree species have been introduced into plantations, resulting in an increased tree species richness and increased forest structure complexity, the restoration of previously mined areas using nitrogen fixing trees has been focused on soil improvement (Bohre & Chaubey 2014).	cache/biotropia-1176.pdf	txt/biotropia-1176.txt
