If you want to stick with or at least compare a mulivariate tree with other approaches (like CCA or mvabund or boral) then the partykit package provides an implementation of a multivariate tree model, using conditional inference trees (i.e. you use conditional inference to decide if spits are "significant" and stop splitting when they aren't rather than the classic build a big tree and prune it back with cost-complexity pruning and cross-validation.
An illustration with the classic hunting spider data set (which was used in the mvpart paper too IIRC) can be found at the end of one of the vignettes supplied with partykit: https://cran.r-project.org/web/packages/partykit/vignettes/ctree.pdf When I used this recently to replicate an analysis from a book chapter I wrote a few years back, the partykit implementation worked well after a little fiddling, but some of the plot options for the terminal nodes don't work so well if your species response matrix has many columns in it (i.e. lots of species).
