AZ 3. Canelo Hills Cienega. Acreage: 60. 



Location: Santa Cruz County; O'Donnell Canyon Quadrangle; 1.7 miles NW of 

 Canelo. 



Description: The rarest of the cienega plants is an orchid, Spiranthes 

 michuacana, presently known in Arizona from no other locality. An adjacent 6 

 acres of similar hahitat with willow, cottonwood, blue-eye grass, and showy but- 

 tercup (Ranunculus micranthus) occur on private land belonging to Bud Ewing. 

 Mr. Ewing's land should be considered for National Landmark status along with 

 TNC property, formerly the Knipe Ranch. Both of these cienegas are important 

 in our paleoecological studies. They provide information on the modern pollen 

 rain of a habitat once more widespread through southern Arizona. Most of them 

 were eroded and drained starting in the mid- 19th century. 



Ownership: TNC and Mr. Ewing.
