it's a wake-up call.
Although the schools are HISTORICALLY black, many are no longer predominately black. I don't think it poses a danger to the schools with long histories and strong traditions (IMO, the more prestigious / private)... but to the state schools that have to fight for funding this is a very real issue. the more students enrolled, the more funding you will recieve.
side note: when i was at
NCCU (undergrad in the late 90s), the admissions department ALWAYS found non-AfAm students to feature on the recruitment brochures. Our law school and grad programs were ALREADY majority non-AfAm.
