Fewer Younger Cacti
Experts say that there have been fewer and fewer younger cacti around as climate change has intensified drought conditions. A 2018 survey conducted by the National Park Service in Saguaro National Park found that, of 10,000 cacti surveyed, just 70 were under 15 years old.
“Although the population of saguaros in Saguaro NP is quite healthy, establishment of young saguaros has nearly ceased since the early 1990s in nearly all habitats,” the report concluded.
