Here are the fields for entering information related to vegetation layers (strata, tiers) in a plot. Layer definitions are found in the layer system of your project and are saved with the project (see projects). You cannot switch to a completely new layer system after the creation of a project but if you want to hide or add layers or edit layer definitions you can do so via the layer systems page. However, you should avoid any changes to a layer system if it is already in use in order to maintain data integrity.
