Regeneration Is Seed vs Severity
The claim
Post-fire regeneration is set by the ratio of seed bank to burn severity rather than by burn area.
01The mechanism
Recovery requires surviving seed; severe burns consume the bank, and area only matters through how much of it is severely burned.
02Predictions
- P1Regeneration should track the ratio.
- P2Burned area alone should mispredict.
03Refutation
Regeneration tracking area would remove the severity term.
