🌿 3D Invasive Plant Range Front: Fisher-KPP Travelling Wave, Wind, Allee Effect and Long-Distance Jumps in a Blender Valley

A Blender-built river valley where an invasive plant spreads as a Fisher-KPP travelling wave: wind drift, a strong Allee effect, road corridors, bridge and ridge barriers, fat-tailed long-distance jumps by birds, and herbicide you apply yourself, with independent numerical checks.
