Title: Photographic Guide to Pinyon and Juniper Tree Maturity Classes
Author: * Sink, S.E.
Abstract: Two series of color photographs illustrate the variation in growth habitat of five maturity classes of pinyon pine (Pinus edulis Engelm.) and Utah juniper trees (Juniperus osteosperma (Torr.) Little) froma variety of sites across Northern Arizona. Information provided with each photograph includes a cross-dated age and measures of height, crown radius, and multiple diameters. Three site quality levels alow the user to calibrate the guide to their site and account for miscrosite variation. A pictorial summary of bark characteristics is presented for both species. This photographic guide provides an efficient way to estimate the age of pinyon pine and juniper trees in the field for ecological restoration, as well as general research ecology, in pinyon-juniper ecosystems throughout Northern Arizona and nearly regions.
