Model simplification using anova()

Based on this, I should not remove either of the interaction terms, so I
turned my attention to the main factors. Based on p-values, I removed
HeightInitial and used a call to anova(model1,model2) to see if this
resulted in a weaker model. Here is the output:
Model 1: HeightFinal ~ Treatment + HeightInitial + DiameterInitial + Frost +
HeightInitial:Frost + DiameterInitial:Frost
Model 2: AbsoluteDiameterDiff ~ Treatment + DiameterInitial + Frost +
HeightInitial:Frost + DiameterInitial:Frost
