GROUND FLORA DIVERSITY UNDER MAN-MADE FOREST IN SITE. PART II. NEW INTRODUCTION AND ELIMINATION OF SPECIES IN PLANTATION OF BURSERA PENICILLATA OF DIFFERENT SPACINGS

摘要

The present investigation deals with the assessment of floral diversity in open stress sites and under plantation of Bursera penicillata (Sasse & Moc... HK. ex Stocks) Engl. and to identify new introductions and elimination of species in plantations of different spacings. Elimination of the species in Bursera penicillata plantation under different spacing showed variations between 13 to 15. The maximum elimination of 15 was found in 2m x 2m spacing followed by 4m X 4m spacing (14), 3m X 3m (13) and 5m X 5m spacing (13). With respect to new introductions, the maximum was found in 5mx5m spacing (16), followed by 3m X 3m (11), 4m X 4m (9) and 2m X 2m (7). Elimination was found to be maximum in family Poaceae (4), followed by Papilionaceae (3), Convolvulaceae (2), Caesalpiniaceae (2), Nyctaginaceae (1), Cyperaceae (1) and Malvaceae (1). As far as new introductions were concerned, 5 species were introduced in Poaceae family followed by one each in Convolvulaceae, Euphorbiaceae, Sterculiaceae and Papilionaceae.
