[2] On 7 August 1946, the Northern Negros Forest Reserve was reduced to its present area of 80,454.5 hectares (198,807 acres) with the signing of Proclamation No.

It covers the highland interior of the island and spans the cities and municipalities of Murcia, Salvador Benedicto, Talisay, Silay, Enrique B. Magalona, Victorias, Cadiz, Sagay, Toboso, Calatrava and San Carlos near the boundary with the province of Negros Oriental.

[1] Number of endemic and threatened species of birds[2] have been documented in the park, which includes the Visayan hornbill, Negros bleeding-heart, white-winged cuckooshrike, flame-templed babbler, white-throated jungle flycatcher, Visayan flowerpecker, Yellow-faced flameback, Negros striped babbler and green-faced parrotfinch.

[4] Salvador Benedicto is considered the "Summer Capital of Negros Occidental" where pine trees line its main highway and where two-thirds of the entire town is within the natural park.

Negros Occidental Representative Julio Ledesma IV also filed a bill seeking to create a 200-hectare townsite from the proposed 500-hectare government property.
