(Gen II details (correct--I hope...), "courtesy" of UPokecenter. Still wanna test those mechanics... Gen IV remains messy at best)

Every headbuttable tree can be associated with an index from 0 to 9. Depending on the player's [[Trainer ID number|Trainer ID]], half of those indices correspond to trees with moderate encounter chances, while the other half correspond to trees with a low encounter chance.
Every headbuttable tree can be associated with an index from 0 to 9. Depending on the player's [[Trainer ID number|Trainer ID]], half of those indices correspond to trees with moderate encounter chances, while the other half correspond to trees with a low encounter chance.
A tree's index depends on its X and Y coordinates in the map; that is, its distance from, respectively, the westmost and and northmost edges.
