The behaviour in Vue 11 is no different to what it was in Vue 10.5 and earlier. The only thing that has changed is that the proportions are now expressed as percentages instead of as numbers.
Jonj1611 try the following, open the previous version of Vue that you have installed prior to Vue 11. Create a terrain, edit the material, create an ecosystem layer, add two plants, Summer Cherry and Fir Tree, set each Presence value to 1, hit populate, note the number of instances, change the presence value of each plant to 2, hit populate, the number of instances doesn't change.
In Vue 11 the percentages are simply a way of expressing the proportions of the different rocks, plants, or objects that will be populated.
The Density controls how many instances you get.
Unless you have the parameter "Avoid Overlapping Instances" set to checked the coverage may well exceed 100% at high values of the Density parameter.
To my way of thinking in a scene with trees and ferns the ferns, being ground cover, would be better placed on a separate layer.
Using percentages to talk about actual number of trees being placed doesn't make any sense, as it is not possible to say what the maximum number of trees would actually be! You could talk about percentage coverage, and that could clearly be much higher than 100% either for a single species or for a number of species in agregate.
