We have devoted several retrospective, or chronosequence studies to understanding the nature and pace of vegetation change as conifers have invaded meadows at Bunchgrass Ridge.

Two of these studies were conducted in the same plots used previously to reconstruct tree invasion history and subsequently for the restoration experiment. By linking retrospective with experimental studies, we are able to assess how the history of vegetation change—including the duration of tree influence—may affect the potential for meadow restoration.
