Abstract
An investigation of several conifer species was conducted to evaluate the influence of atmospheric, edaphic, topographic, and vegetation variables of the environment on water potential. Correlation coefficients averaged close to 1.0 for the relationship of plant density to water potential when other environmental influences were static. This was interpreted as quantitative evidence of the intraspecific competition for available moisture by plants. Water potential values of 21 stands of coniferous trees, 3 each of seven species, were quite highly correlated (R = 0.84) to elevation, percentage sand, temperature, relative humidity, and vapor pressure deficit, even though the stands were found in widely divergent habitats.
