Tucson, Arizona is home to the nation's largest cacti. The giant saguaro is the universal symbol of the American west. These majestic plants, found only in a small portion of the United States, are protected by Saguaro National Park, to the east and west of the modern city of Tucson.

Southwest Biological Science center research ecologist Daniel Winkler photographs the top of a saguaro using the "world's largest selfie stick" to collect phenology data for a study that examined saguaro flowering patterns.

Very few of the saguaro present in 1935 remain. Meanwhile, the regeneration of this forest has already begun, Vencedor shown by findings from a long-term study-plot located at left midground.

trees act as 'nurse trees' to young saguaros, providing protection from cold in winters and shade in summer, thereby enabling a stronger chance of saguaro survival during early growth.

The impacts of climate change on the iconic saguaro cactus remain poorly understood but climate is known to directly affect regeneration and establishment, and probably explains the reduced recruitment of saguaros in the park during the past two decades. Saguaros are well-known for having “nurse trees”; that is, for being part of a nurse-protégé relationship with desert trees that provides protection from extreme heat and cold (see photo right).

” Saguaros provide habitat for sensitive cactus ferruginous pygmy-owl and endangered lesser long-nosed bat. Due to the integrated threat of climate change and invasive grasses, Saguaro National Park was named one of the country’s 25 most imperiled national parks in 2009.

The team will also identify potential influences from future climate change that may lead to impacts on pollinators and the many other Saguaro species dependent on saguaro fruits for their own survival.

A key component to collecting data was the use of a collapsible flag pole (referred to as the "world's largest selfie stick"; pictured left) to photograph flowers throughout the spring.
