Do red dots mean a site is "bad" in some way?

When viewing a map, the resulting sites are generally color-coded for ease of interpretation. When analyzing species richness, for example, some sites will rank "higher" (green) than other sites (yellow or red). This does not automatically mean that one site is "better" than another, for various reasons :

> One site may have more plots than another
> One site may have been surveyed more years than another
> One site may have more variety in habitat types than another
> The "richer" site may in fact have lower quality taxa, or more non-natives

We therefore suggest that you analyze data in a multiple ways in order to rule out any of these possibilities.
