How did the Natural and Historical Monuments Act of 1923 limit heritage protection?

A major shortcoming of the Natural and Historical Monuments Act of 1923 was its narrow view of what counted as heritage. The law concentrated on monuments and sites that reflected colonial and Eurocentric perspectives, frequently excluding the traditions, places and histories of indigenous and local communities. Consequently, many culturally important sites and practices meaningful to the majority of South Africans went unrecognized.
