Cluster analysis for different plant species with elevation, aspect, slope rasters using ArcGIS Desktop?

Question

I am using ArcGIS Desktop.

I have a point shapefile for 5 different plant species and rasters (elevation, slope, aspect, canopy height). I am trying to find clusters for each species in terms of raster values (elevation, slope, aspect, canopy height). I need to figure out where cluster are spatially and significantly. So far, I ran extract multi values to points, and I have raster values for each point in attribute table. Then, I got stuck!

Do you have any ideas what to do next to have a visual layer ( raster or vector) where it shows the significant clusters?

One possible solution to your problem could be the following:

1) Go to Layer > Add Layer > Add/Edit Virtual Layer...

2) In the Create a virtual Layer window you could rename the default layer name, then press the Import button. After that, you will select the layer to embed and then you'll press ok.

3) Now, you have a virtual layer which will serve for our analysis. Open the virtual layer Properties, go to General tab and press the Query Builder button.

In the Provider specific filter expression please enter the following statement: "PlantType" = 'Persimmon'

5) If you wish, you could specify a label for the virtual layer features...

and finally you set a Heatmap style.

6) Now, you can easily identify where the Persimmon cluster is spatially significantly. Of course, you can set more complex queries, as desired.
