This week we went to Ajo,Arizona to visit the Cabeza Prieta National Wildlife Refuge. On our ﬁrst day there, we met up with our contacts from Fish and Game and went out to a wild life water tank where the endangered Senoran pronghorns can drink. There was still heavy equipment tracks everywhere from the installation of the watering hole. We covered the tracks and spread out vegetation to rehab the area and make it look more natural. We made short work of the project and thoroughly impressed our agency contacts. The next day we went out and brushed an old original road as the reroute wasn’t in accordance with the Wilderness plan. WE made short work of what the agency thought would take all day (there seems to be a theme here!) Along the way we encountered border patrol and had a discussion about the politics of managing border lands between different agencies. We really got to witness ﬁrst hand how agencies are dealing with illegal immigration. During this week we saw several endangered species including the Pupﬁsh and Senoran Pronghorn.
