(d) Solidigo esernper>vir>en.8 . Thirty-one quadrats with Solidago 

 (sempeyvlvens were buried by between 5 and 67 centimeters of washover sand. 

 Solidago sempefViTgns in 12 quadrats (38 percent) recovered from as much as 56 

 centimeters of buri.'l; a total of 19 quadrats failed to recover from overwash 

 burial (Table 25). 



Comparisons of recovered quadrats to quadrats that failed to recover, 

 usin;j the Kruskal-Wallis test, show that recovery from burial is not related 

 to initial cover, initial density, or burial depth (Figs. 52, 53, and 54).
