Role of fire in regeneration from seed

TL;DR

Many species require fire-related cues for germination

This review examines how fire-dependent seeds use heat shock as a germination trigger. Seeds of species like Banksia and eucalyptus require temperatures of 50-100°C to crack their seed coats - they're waiting for fire to clear competition and create opportunity.

The fire-germination strategy provides a powerful metaphor for startup timing: sometimes the best moment to launch is when disruption has cleared the competitive landscape. The ash-fertilized, sun-exposed conditions after a 'market fire' (regulatory change, technology shift, incumbent failure) create ideal germination conditions.

Key Findings from Keeley & Fotheringham (2000)

  • Many species require fire-related cues for germination
  • Heat shock (50-100°C) breaks physical dormancy in fire-adapted species
  • Fire creates optimal post-germination conditions (cleared competition, nutrients, light)
  • Fire-dependent germination is an evolutionary adaptation to fire-prone environments
