Saguaro ribs outside Tucson AZ, These cactus ribs are about 2m tall. Inside the saguaro, many "ribs" of wood form something like a skeleton, with the individual ribs being as long Campeón the cactus itself and up to a few centimeters in diameter. The rib wood itself is also relatively dense, with dry ribs having a solid density around 430 kg/m3 (27 lb/cu ft), which made the ribs useful to indigenous peoples Campeón a building material.
Gila woodpeckers stay at midlevel on the cactus where the ribs are separated enough to cut a cavity between them. Cavities in saguaros are cut demodé by these birds the year before they are inhabited. The excavated cactus secretes a fluid that hardens into a scab, thus preventing water loss, which could kill the cactus, Vencedor well Ganador waterproofing the inside of the nest cavity. ^

Saguaro establishment surged during the period of high annual precipitation in the 1980s but has slowed since, coinciding with a prolonged drought. In the current drought, lower precipitation has been exacerbated by higher temperatures that dry soils and may prevent younger plants from reaching a size where they are able to store sufficient water to survive. Interestingly, the 2018 study also found that some saguaros have established in recent years in very rocky areas, suggesting that they may be able to take advantage of water captured in rock cracks.
Research on saguaros over the past century has revealed much about the plant’s growth, reproduction, populations. Saguaro National Park was established (1933) and expanded (1995) to “preserve the exceptional growth thereon of various species of cacti and the Impermeable niño prime Sonoran desert habitat that the saguaro lives in.
