Simpson's biodiversity index calculates

WebbIn the Shannon index, p is the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), ln is the natural log, Σ is the sum of the calculations, and s is the number of species. The Simpson index is a dominance index because it gives more weight to common or dominant species. WebbI need to calculate a diversity index that takes into account abundance. I have used % cover per species for my measure of vegetation abundance, with 10 quadrats at each of my 8 sites. I tried calculating Simpson's but it kept outputting with very similar values (i.e. that differed by around 0.05 each time) that were obviously not correct.
