kepelbagaian spesies pteridophytes di ladang kelapa sawit di segamat, johor

abstract the research of this study is to discuss the distribution of pteridophytes at muka head field station, pantai acheh, pulau pinang. from the study, there were 265 individuals been observed throughout a total of 30 plots (20m x 20m). the mean of fern abundance at ea1m is 11.46 while the mean for eb1m is 9.23. 4 species were found at the ea1m while 11 species were found at eb1m. the most number of species found is taenitis blechnoides from the family taenitidaceae. it can be found at both ea1m and eb1m. dicranopteris curranii can also be found at both elevation but restricted to only 4 plots ; 1 at ea1m and 3 at eb1m. this is because of the geographical condition factor. other than that, the species diversity and species evenness are higher at eb1m with a value of 1.392 and 0.605 respectively, while at ea1m the species diversity and species evenness is only 0.353 and 0.321 which is lower than that of eb1m. taenitis blechnoides has the highest relative abundance and relative frequency in this study hence we can conclude that t. blechnoides were the dominant species found at muka head field station forest area. on the other hand, a correlation, r2 was calculated to determine the correlation between the fern abundance and the abiotic factors. the abiotic factors that were taken into account are humidity, temperature, light intensity and soil ph. from the data calculated, it shows that was a weak correlation between the two variables, which is the fern abundance and abiotic factors. by using morisita’s index, the distribution pattern of the fern is clumping since the value is closed to one.
