In December, Sky Island Alliance volunteers took to the trails in Saguaro National Park East District to count and measure saguaros as part of the Saguaro Census. Every ten years, Saguaro National Park inventories the population of saguaro across 45 large plots with help from the community. They look for changes in the total number of saguaro and how big the iconic cacti are at the time of measurement.
The first results of the 2020 Saguaro Census are in. In the plots measured by Sky Island Alliance volunteers on December 7th and 10th, there are slightly fewer total saguaros this year, but the average size of young saguaros has increased. We’ll have to wait and see how all the plots measure up before we can really understand how the population of park saguaros is changing.
The next groups of volunteers hit the trail to help with the survey on January 10th and 11th, so more results will be pouring in soon!
