Glenn De'ath published a paper in 'Ecology' several years ago and included S-Plus functions in the archives. I haven't looked at the files, so I'm not sure what modifications would be necessary for R.

De'ath, G. 2002. Multivariate regression trees: a new technique for modeling species--environment relationships. Ecology 83:1105-1117.
