Abstract
We introduce new invariants of a class of toric surfaces (including the projective plane) that arise from appropriate enumeration of real curves of genus one and two. These invariants admit a refinement similar to the one introduced by Grigory Mikhalkin in the rational case.

Comments
This is a substantially revised version: two signed counts of real curves of genus 0, 1, and 2 are introduced, both giving real enumerative invariants; two extremal cases are excluded from the main theorems
