Appendix A. Photographs (Figs. A1–A5) showing Jackrabbit Spring pool and representative native vegetation reaches, saltcedar reaches, and cleared reaches during and after removal of saltcedar.

 
   FIG. A1. Jackrabbit Spring pool. Pool measures ~10 m across and ~3 m deep. Spring outflow is not visible.

 

 
 
   FIG. A2. Native upstream vegetation reach. Scattered ash and mesquite trees create an open canopy above the stream (a) and bulrush line the stream banks (a, b). The dark material that can be seen in the stream channel is filamentous algae (b). Both photos were taken during winter when bulrush are senescent.

 

 
   FIG. A3. Native downstream vegetation reach. Arrow marks the location of the stream.

 

 
   FIG. A4. Typical saltcedar reach. This photo was taken in the winter when saltcedar had already dropped its leaves. The light brown material covering the ground and tree limbs in this photo is saltcedar leaf litter. The dark material in the stream is saltcedar leaf litter and saltcedar roots.

 

 
 
 
   FIG. A5.  Clearing saltcedar, and a representative cleared plot following clearing.  Clearing each 30 m reach took between 2–6 days with 2–5 person crews (a). The person seen in this photo is standing in the stream, which moves from right to left (a). The same stream reach 3 months (b) and 3 years (c) after clearing with arrows marking the approximate location where the person was standing in 5a. Photos 5a and 5c were taken in the winter. Photo 5b was taken in the summer.
