Hi Philip,

your data are event times because you're monitoring the same trees in 
each plot over time, the event being death of a tree.

Therefore methods from survival analysis are more appropriate.
Start out having a look at the package survival, possibly considering 
a Cox model with adjustment for clusters or with strata (the function 
coxph()) or a parametric model using the function survreg().
