Saguaro Census 2010

NPS

Every 10 years, Saguaro National Park leads a "Saguaro Census" of the park's namesake cactus. This effort helps us keep track of the health of the park's saguaro population and coincides with the U.S. Census. As the United States counts its citizens, we count our saguaros! The 2010 Saguaro Census took place between October 2009 and October 2010 with the help of over 300 volunteers.

You can take a look back at specific survey dates and plots for the 2010 Saguaro Census using our Saguaro Census Calendar. Click on the highlighted dates on each calendar to view the results and photos from past volunteer groups.

The Saguaro Census continues with a special survey of historic section 17. Follow the link below for more information.

Javelina

"Don't call ME pig!" Javelinas are able to eat spiny prickly pear pads with no obvious harm to their mouths, stomachs or intestinal tracts due to an enzyme in their saliva. Javelinas are not true pigs, they are peccaries, which are native to the Americas. True pigs are native to Europe and Asia. Wild pigs and boars are descended from true pigs brought over on boats to the new world.
