Site notation is as follows: (1) hardwood forest, and (2) Calocedrus and (3) Cryptomeria plantations in Wulai; (4) hardwood forest in Huoshaoliao; (5) hardwood forest and (6) Calocedrus plantation in Lienhuachi; (7) Chamaecyparis forest in Yuanyang Lake.
^aOTUs formed at an evolutionary distance ≤0.03 (or about >97% similarity). Data with the same letter in each row indicates no significant difference by LSD test at P<0.05.
^bTotal number of clones in an OTU.
^cNumber of clones in each library.
