Invasive plant species of Aravaipa Canyon

posted Feb 20, 2020, 1:40 PM by Peter Else

LSPWA member Phil Hedrick has led the effort to rid Aravaipa Canyon of invasive plant species for the past 25 years, and he has done so without financial grants for labor.  He does not spend a lot of time in planning meetings or talking about this effort.  He’s a doer, not a talker.  He spends most of his time in this conservation effort as a volunteer on the ground, actually removing these invasive plant species, particularly tamarisk (“salt cedar”) trees and the invasive annual, Sahara mustard. 

If you are with Phil in a car or out hiking when he spots an invasive plant, everything stops and the plant is either removed or marked for removal.  Over the years, he has received help from his wife, Cathy Gorman, from the late Aravaipa Canyon Wilderness Area Ranger Patrick O’Neil, from current Aravaipa Ranger Heidi Blankenship, from Mark Haberstich of the Nature Conservancy, from fellow Aravaipa landowner George Leys, and from other volunteers he has been able to enlist.

Phil is a model for citizen-based action and scholarship within the LSPWA.  Attached below is the recently published article that Phil wrote along with coauthors Blankenship and Haberstich:
