Fire Enhances Whitebark Pine Seedling Establishment, Survival, and Growth
Pages: 84-99
DOI: 10.4996/fireecology.1102084

Periodic fire is thought to improve whitebark pine (Pinus albicaulis Engelm.) regeneration by reducing competition and creating openings, but the mechanisms by which fire affects seedling establishment are poorly understood.  I compared seedling vegetation production in adjacent sites, one last burned in 1880 and the other in 1988, to test the hypothesis that recent fire increases whitebark pine seedling growth.  I experimentally tested effects of fire on seedling recruitment and growth by planting seeds in prescribed burned and nearby unburned sites.  Experimental results showed nearly three times greater seed germination and seedling survival in recently prescribed burn plots.  [Read More]
