Protea vogtsiae has a restricted distribution range in the mountains of the Western and Eastern Cape Provinces of South Africa, with an extent of occurrence (EOO) of 2123 km², and an area of occupancy of 384 km². It is known from more than 10 locations and is suspected to be overlooked and to be more common than current records indicate. It is therefore not considered to be in danger of extinction and is listed as Least Concern.

Kouga Grassy Sandstone Fynbos, Kouga Sandstone Fynbos, Tsitsikamma Sandstone Fynbos
It grows on steep, rocky, south-facing slopes in sandstone fynbos, 1000-1500 m. It is a long-lived species, and survives fires by resprouting from underground stems. Wind-dispersed seeds are stored in fire-resistant inflorescences, and released after fires. It is pollinated by rodents.
Many of the lower altitude, accessible subpopulations were destroyed by agriculture and a total of 7% of this species' habitat has been lost. Recent field observations noted alien invasive plants present in the habitat of several subpopulations in the Outeniquas and Baviaanskloof. These could outcompete native species in future if left unmanaged.

A total of 29 subpopulations are known, all are isolated and small. It is however, probably more common than reported because of its inconspicuous habit. More field surveys are required to determine the status of the population and to determine if it is declining.
