Currently, abandoned land looks pretty depressing on the mainland with it being utterly devoid of any plant life, and the repeating ground texture isn't doing it any favors, either.

I feel the governance team should have access to some kind of script or function that takes abandoned land on the simulator, and randomly populates Linden Plants and Trees onto the parcel. The built-in plants are good enough for background vegetation and are relatively cheap to render.

There are obviously some considerations needed, such as terrain height and water height limiters, as well as biomes/themes for each continent. Ideally, a grid-wide auto-populator batch script would reduce workload for governance, though I'm uncertain of how much the region conductor is aware of abandoned land. Even if existing abandoned land is impossible to automate in this way, it's far more likely that it's possible to add an auto-populate script to the workflow of reclaiming land.

I sincerely hope something like this is possible as the barrenness of mainland is a detriment to the user joy of mainland residents. I know it certainly reduces my joy in its current state.
