Natural Regeneration of Oak Woodlands in Southeastern Arizona

Abstract

The lack of information on the reproductive dynamics of Western Live Oak formations has created a need for the collection of baseline data. Therefore, a survey of the state of oak regeneration was conducted at several sites in southeastern Arizona. Presence, type, and amount of regeneration were recorded on 108 temporarily-established transects, on seven sites. Parameters examined for their influence on regeneration were aspect, soil, slope, and density. Frequency distributions and chi-square tests were used to analyze the data. Analysis showed that, when the data are pooled, all the parameters have an influence on the presence and distribution of regeneration. On individual study areas, parameters have limited influence or none at all. Further information will have to be gathered before conclusive statements on the dynamics of oak regeneration can be made.
