Differential Establishment of Pinyon and Juniper Following Fire
American Midland Naturalist
(1988)
Abstract
Reestablishment patterns of singleleaf pinyon (Pinus monophylla Torr. and Frem.) and Utah juniper (Juniperus osteosperma (Torr.) Little) following a midnine-teenth century fire were investigated on a southwestern Utah site. Pinyon and juniper ages were estimated on 12 plots from growth ring counts. Thirty-eight percent of the juniper, but only 0.6% of the pinyon alive at sampling were older than the fire. Juniper seedlings initially reestablished at higher densities than pinyon. Pinyon density exceeded that for juniper by about 60 years after the fire and had nearly six times the density of juniper 145 years afterward. Patterns of establishment were also more variable for juniper than pinyon. Reestablishment levels for pinyon and juniper after the fire were lower on plots with higher densities of juniper that survived the fire.
