| 18 | )))|The Shannon Diversity is a very common index used in ecology to quantify diversity in a community. The index provides more information about the fauna and flora composition than simply area richness. It takes into consideration both the number of different species observed and their relative abundances | ||

| 55 | * Shannon Diversity Index it is calculated as follows: | ||
| 56 | * [[image:1646226002850-314.png]] | ||
| 57 | * Pi is the proportion of total number of individuals of ith species, divided by total number of individuals of all species recorded. | ||
| 58 | * Shannon Diversity Index needs semiquantitative data. In our case, data must be collected through linear transects (linear paths with fixed length), in which experts record number of specimens for each species | ||
| 59 | * Butterflies survey: at least once a month from April to September | ||
| 60 | Bees survey: at least once a month from April to September | ||
| 61 | Plants survey: at least once a month from April to September | ||

| 64 | ====== **Level of expertise required** ====== | ||
| 65 | )))|((( | ||
| 66 | * Shannon Diversity Index is easy to apply but data collection requires a high level of taxonomic knowledge, in order to recognise the correct species, for each target taxon. | ||
