According to the Simpson’s diversity index calculations of all the sites in figure 7, Site 3 had the highest index reading of 0.701 out of 1. With 1 being the highest possible value, it indicates very high diversity while 0; the lowest possible value, indicates no/very low diversity. This suggests that 0.701 is a high reading, indicating high diversity of plant species. The analysis of the first hypothesis ‘There is a direct correlation between the diversity of plant species and the relative humidity at each site’, will help explain why site 3 had the highest diversity index reading when compared to the other sites. To answer this hypothesis, data will be used from graphs in figure 2, 3 and 4. It can be suggested from figure 2, 3 and 4 that the abiotic conditions of site 3 have proven to increase the diversity of plants when compared to other sites. For plant A, according to figure 2, the humidity (rH) decreases from 64% in site 2 to 50.1% at site 3 while the total number of plant A increases from 9 in site 2 to 80 in site 3. Even though the diversity of plant A increases with a decreased relative humidity in Lamma Island, this is not supposed to occur in general according to theory as higher levels of relative humidity are supposed to increase biodiversity, not decrease biodiversity. Theory suggests that a higher level of humidity is supposed to decrease the effect of solar radiation while a lower level of humidity is supposed to increase the effect of solar
