Annual Pima Pineapple Cactus Survey — January 4-8, 2021

The Buenos Aires National Wildlife Refuge provides a habitat for the critically endangered Pima Pineapple Cactus.

The Refuge does prescribed burns in different areas each year to maintain and improve the grasslands that support the other species for which the refuge is known. Before each burn, they need to survey the presence and condition of the Pima Pineapple Cactus. They need help to do this. If you can help, contact Reta Rutledge at

Volunteers will be trained in data collection and how to identify and discriminate between the endangered pima pineapple cactus and other barrel-type cacti. Joining the rest of the crew in a line, they will participate in an organized grid survey, walking transects. January 4-8, 2021.

The project is designed to identify the location of the endangered pima pineapple cactus and to measure the effect of controlled burns and other fire management strategies.
