Monumento Natural da Serra da Rajada, Natural monument in Caucaia, Brazil

Monumento Natural da Serra da Rajada is a protected natural area covering several hundred hectares of forested slopes and highland vegetation near Fortaleza. The site features diverse plant communities adapted to its elevated terrain and varying moisture conditions.

The monument was officially established in 2019 following scientific research that documented its ecological importance and the rarity of its vegetation. This designation came after studies showed the area needed legal protection to remain intact.

The technical survey for the monument included a historical study with the quilombola community living in the Tucunduba area. The creation decree was signed during Ceará's Environment Week, an event involving about 130 municipalities and 26 state conservation units, sponsored by SEMA.

The monument lies in the Tucunduba district of Caucaia, in the Fortaleza metropolitan region, with Pedra da Rajada as its highest point and main draw. The protected area covers 373.85 hectares, with the strict monument zone on the summit and a buffer zone around it. The technical fauna and flora survey and the historical survey with the resident quilombola community were completed before the 2019 decree.

The area preserves Atlantic Forest remnants including bromeliads and orchids that thrive in the mountain climate. This forest type survives in very few places across the region, making it one of the last examples of its kind.
