Select Sites from the content menu on the right of your project overview.
On the top right of the Site list, click on the plus icon.
The Site creation form will open.
Start by naming the new Site and describing it, including its role for the project.
Next, define the Site type by selecting one or more categories.
You can add more than one category to your Site type. E.g., if your Site is a conservation area which includes smaller reforestation patches, then you would select the categories "conservation" and "reforestation". Note that the category on the top will define its styling on the map (icon and color). You may change the order of the selected categories at any time, or delete them using the trash icon.
