It occurs on rocky, east-facing sandstone slopes, 1100-2100 m. Mature individuals are killed by fires, and only seeds survive. Wind-dispersed seeds are stored in fire-resistant inflorescences, and released after fires. It is pollinated by birds.
Protea scabriuscula is potentially threatened by alien invasive species which are already present at low densities and too frequent fires.

This species is known from 18 small isolated subpopulations which are not declining.
