AN ACT
TO RECLASSIFY THE MANGABUL RESERVATION IN THE MUNICIPALITY OF 
BAYAMBANG, PROVINCE OF PANGASINAN, INTO ALIENABLE AND 
DISPOSABLE OF THE PUBLIC DOMAIN FOR THE PURPOSE OF 
REDISTRIBUTING THE SAME TO THE BONAFIDE AND LONG-TERM 
FARMERS/OCCUPANTS THEREOF, AND FOR OTHER PURPOSES
EXPLANATORY NOTE
Located in San Gabriel 2nd, Bayambang, Pangasinan, the 2,059 hectares-area 
of the Mangabul Reservation was declared by the Bureau of Lands as insular public 
domain in 1933 by virtue of Act No. 4041. This reservation used to be partly forested 
and partly a lake. This same Act awarded the usufructuary rights to the town over the 
fishery area that was referred to as the Mangabul Fishery Reservation.
Over time, the forested fractions of the reservation were converted into 
agricultural production and the accumulation of silt over the years and the lahar that 
flowed from the eruption of Mt. Pinatubo has lessened the fishery area into a few 
shallow creeks during the dry season. Presently, the entire reservation has become 
farmlands and residential area comprising of eight (8) barangays.
Controversies arose between the farmers and occupants, and the municipality 
and the lessees of the fishery reservation. These disputes resulted in many civil and 
criminal cases, but the courts always recognized the right of the farmers to the 
possession of the lands.
In 1993, the Department of Environment and Natural Resources (DENR) 
declared the municipality's usufructuary rights terminated under Article 605 of the Civil 
Code which disallows usufructuary rights to last in excess of 50 years. When the court


decided in favor of the DENR's claim, the municipality of Bayambang appealed the 
decision and the case remained pending since.
In order to settle the legal issues and agrarian unrest surrounding this matter, 
this proposed measure aims to: reclassify the Mangabul Reservation into alienable and 
disposable land of the public domain, distribute the land ownership to bonafide and 
long-term farmers and occupants, and grant the usufruct over the remaining creeks 
in the area to the Municipality of Bayambang, which shall be managed and developed 
by the farmer-occupants themselves upon payment of reasonable compensation to 
the municipality.
In view of the foregoing, the early passage of this bill is earnestly requested.
