An arboreal Galois representation is the dynamical analog of the Galois representations attached to elliptic curves. A dynamical analog to Serre's open image theorem, conjectured by Jones, remains largely open. We prove a version of Jones' Conjecture for quadratic and cubic polynomials assuming the abc-Conjecture and Vojta's Conjecture. We also exhibit a family of degree 2 rational maps and give examples of degree 3 polynomial maps whose arboreal representations have finite index in the appropriate group of tree automorphisms.
