Their deep root systems bind thee soil, while thee forest canopy andd leaf litter protect thee ground from thee impact of heavy rainfall.

Native andEndemic Bird Species

Te Galápagos are mean for their bird life, including ding Darwin 's finches, Galápagos mockingbirds, filghtless cormorants, and the Galápagos hawk, among many others. Many of these species depend on nativa fores for nesting sites, foraging habitat, and providention from predators. Deforestation reduces the acvability of these resources and fragments bird populations into smallar, more istated groups.

Thee Galápagos petrel (bei1; Vel1; FLT: 0 + 3; Pterodroma phaeopygia presendi1; FLT: 1 + 3; FLT: 1 + 3;), an endangered seabird that nests only in thee highlands of the archipelago, provides a striking example.

Reforestation projects focus on planting nativa tree species, specially arly scalisia, in areas where presert cover has been lost.
