Effects of Ozone on Understory Vegetation in the Mixed Conifer Forest

  • Patrick J. Temple
Part of the Ecological Studies book series (ECOLSTUD, volume 134)


The mixed conifer forest ecosystem of the San Bernardino Mountains includes all the producers (plants and algae), consumers (animals and other heterotrophs), and decomposers (bacteria, fungi, and other single-celled organisms) found in the forest, all of which contribute to the complex processes of energy flow, storage, and biogeochemical cycling. Although not the dominant vegetation, the herbaceous and woody plants of the mixed conifer forest understory are a significant part of the forest ecosystem. Although the effects of ozone on the dominant overstory trees, particularly ponderosa (Pinus ponderosa Laws.) and Jeffrey (P. jeffreyi Grev. & Balf.) pines, have been extensively documented, relatively little is known of the effects of ozone on the shrubs and herbaceous plants of the understory.
