In recent news, Crow Valley was also laid claim by some 508 Aeta families as ancestral domain. The Department of National Defense has rejected the claim. After the 1991 Pinatubo explosion, and the turn over of the US military facilities, Pres. Fidel Ramos announced Proclamation No. 163 (1993) where Crow Valley was specifically exempted from the coverage of the Bases Conversion Development Authority (BCDA), and is primarily reserved for the use of the Armed Forces and the Defense Department.
