I have a number of sites in a habitat where I am assessing biodiversity via Shannon index. I am calculating Shannon's diversity of birds, mammals, trees, shrubs, herb,s etc. Can I get a single SW value for each site by combining these taxa or is there a better way? My aim is to present this to managers for intervention planning by ranking these sites as good, average or low diversity plots and thus planing their intervetions accordingly.
"BiodiversityR" package allow you to do so. Kindly check. Kindly check it's vignette file.
Sure, I will check thanks. My question was more of a conceptual level. Can I combine species data for different taxa to get a single SW is fine,or there is a better way to do it?
you mean Shannon weaver? if so, it's a good indicator of diversity, it's perfect
Yup, that's also fine. Also i would like to suggest the following
1. Include other diversity index like evenness, richness and abundance.
2. Diversity index for each taxon group
3. Diversity index for threatened species (if available).
Thanks Ratnesh Karjee , I am already giving all these diversity indices (not the threatened species one). But as the managers want their hand on a single indicator, I am using a combined diversity SW value. Ratnesh KarjeeLinda Cheriak is the Shannon - Weaver correct name for it or Shannon-Weiner, I saw references to both in various texts. I will use the Shannon index to avoid this confusion.
