The species richness is when we talk about the actual number of species in a community. For example‚ if you go to a bottom ground forest you might see only sugar maple. Therefore‚ the species richness is only 1. Shannon Index measures species diversity too‚ but takes into account species evenness. Species evenness is when the relative abundance of the species in that community are more similar to each other. So by knowing that you have more similar species‚ this allows you to more accurately determine

The invasive species are harmful for native systems and time and money should be invested to prevent these species from spreading and damaging systems that they are not native to. Strict rules for environmental obedience are necessary and good. Much more needs to be done to protect our planets and its biodiversity from the invasion of alien species. When non-native species from other ecosystems are introduced‚ they can upset that balance and bring harm to the established plants and animals‚ and
