Population size fluctuations may be common for these 

 species. Only further monitoring will yield information on 

 population fluctuations. 



RECOMMENDATIONS 



It is recommended that demographic monitoring be continued for at 

 least two more years to better understand the life history 

 characteristics of these species. In light of the results of the 

 morphological overview, it would be appropriate to use techniques 

 of electrophoresis to support the hybridization hypotheses, and 

 delimit the range of the species. Although abundant locally, C. 

 lonqistylum has a very limited distribution, and is still 

 considered a C2 species by the U.S. Fish & Wildlife Service (U.S. 

 Department of the Interior 1990) . Land managers should be aware 

 of this species presence with respect to any planning activities.
