There is need to explore the relationships and assess plant community census and patterns. In 18 grid plots in Dalingshan forest was used to conduct plant community structure and abundance evaluation. Plant and vegetation community types were analyzed using TWINSPAN-PC ORD (Two-way Indicator Species Analysis). A field survey was conducted and GPS based map was established. Field/grid map and TWINSPAN were employed to identify species abundance within spatial nutrient distributions. The study was designed to grid the site at 200 x 200 m spatial patterns. 18 grid plots were adopted to identify species abundance and characteristics and total of 99 species observed. TWINSPAN using the PC-ORD software was applied to develop four groups plot dendogram. The entire field procedure was used to establish species census and abundance spreadsheet which aided census of species at medium abundance identified Rhuschinensis (Rch) of abundance (95), Adiantumcapillus (Aca) abundance (90), Blechnumorientale (Bar) abundance (87) and Agaratumconyzoides (Aco) abundance (80). Species of optimum abundance identified Hedyotisauricularia (Hau) 3767, Miscanthussinensis (Msi) 2520, Lophatherumgracile (Log) 833 and Mikaniamicrantha (Mmi) 803 respectively. In furtherance, the results showed that species of floristic composition identified at optimum abundance in percentage (%) include Hedayotisauricularia (32%), Mikaniamicrantha (21%), Hophatherumgracile (7%) and Mikaniamicrantha (7%). This study thereby suggests that the species evaluation can be utilized for further studies on multifactor ecosystem responses towards regional ecological restoration. However, it is critically required to conduct further studies on spatial patterns of soil nutrient distributions in both forest regimes and at regional level.
