In particular, the string axiverse postulates the existence of up to $\\mathcal{O}(100)$ light scalar bosons constituting the dark sector. Considering a mixture of axions and cold dark matter, we obtain upper bounds for the axion relic density $\\Omega_a h^2 < 0.004$ for axions of mass $10^{-31}\\;\\mathrm{eV}\\leq m_a \\leq 10^{-26}\\;\\mathrm{eV}$ at 95% confidence.
