WHAT THE EVIDENCE SAYS
At 12 sites, paired remnant and recovering plots were assigned different thinning and burn frequencies. Combined high-frequency fire and thinning produced about three to four times more remnant indicator plant species in recovering areas than passive regeneration.
WHY IT MATTERS / OUR READ
Remnant patches are living propagule sources; restoration success depends on keeping those sources and conditions that enable dispersal.
CAVEATS / UNCERTAINTY
Some dispersal guilds responded weakly, and additional seed introduction may be needed. The study informs fire-adapted systems, not a general fire-frequency target.
