Researchers Studying Succession in Three Forest Sites Want to Determine

Essay

Researchers studying succession in three forest sites want to determine how similar the forests are in terms of species composition. Using Jaccard's index, rate the similarity of the three forests (A, B,
C). Show your calculations.

$$\begin{array} { | l | l | l | l | } \hline \text { Tree Species } & \text { Forest A } & \text { Forest B } & \text { Forest C } \\\hline \text { Acer saccharum } & \mathrm { X } & \mathrm { X } & \\\hline \text { Fagus grandifolia } & \mathrm { X } & \mathrm { X } & \mathrm { X } \\\hline \text { Quercus rubra } & \mathrm { X } & & \mathrm { X } \\\hline \text { Quercus alba } & \mathrm { X } & & \mathrm { X } \\\hline \text { Acer rubrum } & \mathrm { X } & \mathrm { X } & \\\hline \text { Prunus serotina } & & \mathrm { X } & \\\hline \text { Liriodendron tulipifera } & \mathrm { X } & \mathrm { X } & \\\hline \text { Carya ovata } & \mathrm { X } & & \mathrm { X } \\\hline\end{array}$$
