Its single most consequential land-use fact is scale: the Quirino Protected Landscape, proclaimed in 2004, covers 175,943.62 hectares — 67% of the entire province's land area — extending into 5 of its 6 municipalities and protecting the headwaters of the Cagayan River. The Ilongot/Bugkalot people, concentrated in Nagtipunan, hold a Certificate of Ancestral Domain Title awarded in 2016 covering over 212,000 hectares spanning Quirino, Aurora, and Nueva Vizcaya. In November 2020, Typhoon Ulysses (Vamco) caused flooding that killed at least 7 people in the province.

A province where 67% of all land area sits inside a single protected landscape is an unusually clear, concrete example of the structural land-use constraints a live cross-LGU dashboard is built to keep visible for every municipality's planning office.
With two-thirds of the province inside a single protected landscape, Quirino's PPDO has a genuinely concentrated land-use constraint to manage well. A Nova Gov pilot brings that alongside its strong SGLG record into one view across all 6 municipalities.
