Let $T$ be a locally finite rooted tree and $B(T)$ be the boundary space of $T$. We study locally compact subgroups of the group ${\rm TH}(B(T))=\langle {\rm Iso}(T),V\rangle$ generated by the group ${\rm Iso}(T)$ of all isometries of $B(T)$ and the group $V$ of Richard Thompson. We describe orbit equivalence relations arising from actions of these groups on $B(T)$.
