  It is well known that dark matter density measurements, indirect and direct
detection experiments, importantly complement the LHC in setting strong
constraints on new physics scenarios. Yet, dark matter searches are subject to
limitations which need to be considered for realistic analyses. For
illustration, we explore the parameter space of the phenomenological MSSM and
discuss the interplay of the constraints from dark matter searches and the LHC,
and analyse the impact of the astrophysical uncertainties in some detail.
