Terrestrial Liming As a Restoration Technique for Acidified Forest Ecosystems

Table 1

Effect of liming on vegetation, with parameter estimates for the year-treatment interactions with 95% highest posterior density (HPD) intervals from Markov Chain Monte Carlo samples from repeated measures analysis of data collected in PA before and after lime application on two of four forest sites. All of the confidence intervals (CIs) include zero, indicating no significant effect of liming on those variables.
