Dissolve combines features that have the same value for a specified feature. The output layer contains simplified features of different values.

Merge combines common features of two or more themes into a single theme. Feature data will be retained if they have the same name.

Clip uses an overlay layer like a cookie cutter on the input theme. The input theme’s data features are not altered in the clipped layer.

Intersect cuts an input layer with the features from an overlay layer to produce an output layer with combined areas that have feature data from both themes.

Union combines features of an input layer with the features froman overlay layer to produce an output layer that contains the feature data andfull extent of both input and overlay layers.

Richness maps were then processed into two classes: Less than or equal to ½ or greater than ½ of the total number of species occurring on private land used to create the map. This map is then clipped with the shape of private land to produce a map of affected and unaffected areas

END

Multiple individual species combined by repeated intersection by species then unioned by number to produce species group maps

In this simple example, two layers like individual species layers are overlaid. The solid red layer is the result on the intersection of them. That is it is all the places that the two layers have in common or for our use where there are two species. This process was repeated for each pair to make the two species layers, each triplet for the threes and so on.

The white areas of the next layer represent the areas where there is at least one species. The different outline colors are left to make the areas recognizable. These areas are then summed by merging to make the lighter red area.

The two layers representing one and two species are then summed to include all of the information in both layers by unioning them. The result is a layer showing all the areas with one or two species habitat. Using the presence of the appropriate habitat as a proxy for the presence of the species.

Input layers: species habitat

Merge of single species = one species habitat areas.

Intersection of the two specie habitat layers = two species habitat areas
