APPENDIX A 

 DETAILED DIAGRAM OF NORTH PADRE ISLAND STUDY PLOTS 



Because the cross-section locations are the same as the surveys made from 

 1975 to 1977, the same plot diagram is included as Appendix A as given in 

 Miscellaneous Report No. 77-8 (Dahl and Goen, 1977). 



Beach profiles are measured from MSL to the East Base Line and the 

 indicated number on each profile is the total distance to the East Base Line. 

 The dashline shows the 30 meters seaward of the grass extension for each 

 profile at the time of the 1976 survey. The solid line shows the length of 

 the 1976 measured cross section across the unplanted area, the 366-meter sea 

 oats dune, and the 366-meter bitter panicum dune. For the dune-width extension 

 and the 335-meter bitter panicum dune, the solid line shows the 1976 distance 

 to the back of the dune only.
