Create a different symbology based on an attribute

Data_TA — Thu, 11 Jun 2026 15:22:03 GMT

Is there a way to add a symbology for points that have a specific attribute when the layer already has a symbology set on a certain field? A layer I use already has symbology set to a specific field named "Planting Season". However, I'd like to create a different symbol for points that have the value "Stump" under the "Genus" field. Is this possible to do if the current symbology is sourced from the Planting Season field?

I have looked at the symbol properties that can be changed based on attribute values but I am looking to use a different symbol entirely. The current symbology based on planting season uses solid-fill dots, and I would like to use a different symbol. Below is an example of the current symbology that's based on the "Planting season" field and how it uses solid-fill dots. Could I create a rule or something that uses a different symbol for points labeled as "Stump" under the field called "Genus"?

An easy way to do this is:
1. Duplicate the layer in the Contents Pane
2. For the newly created copy that is above the existing layer, create a Definition Query Genus='Stump'
3. Symbolize the top layer with your desired "stump" symbol.
4. Keep the original layer below, symbolized by planting season.

I "think" this would work. Question - do you need the stump symbol to be a single symbol or by season year as well?

Use the Unique Values renderer but next to the Field menu, click the Expression button to use a custom Arcade expression to define your classes.

Write an expression that returns "Stump" when the Genus field value equals "Stump", and otherwise return the Planting_Season field.

if ($feature.Genus == "Stump") { return "Stump"; } else { return $feature.Planting_Season; }

The Symbol classes would look like this afterwards:
