Species Richness

There has been a lot of interest on the news recently about the importance of bees and other pollinators. In simple terms, bees are important due to their ability to distribute pollen that allows plants to flourish and for crops to grow, contributing to food security.  In addition, bees also contribute towards biodiversity and the health of our environment.

Spiders at 23 Portuguese protected area sites were sampled (pitfall trapped) over 10-month periods. The data allowed for a “biodiversity quality” assessment consisting of the following indices: Species Richness, Biomass, Simpson Index, Species Conservation Value Index and Population Density. These “biodiversity quality” characteristics were reviewed for relative indication of site spider “biodiversity quality”.
