  In the conventional cosmology masses of the stable supersymmetric relics,
candidates for the dark matter (DM) particles, should be typically below 1 TeV.
This is in conflict with the LHC bounds on the low energy SUSY. However, in
$R^2$-gravity the masses of the stable particles with the interaction strength
typical for SUSY could be much higher depending upon the dominant decay mode of
the scalaron. We discuss the bounds on the masses of DM particles for the
following dominant decay modes: to minimally coupled massless scalars, to
massive fermions, and to gauge bosons.
