1 Control and experimental planting sites on north 



Padre Island 15 



2 Total sand volume for beach and foredune cross 



sections of five study dunes 22 



3 Sand volumes accumulated above planting elevations 



for the immediate locale of planting 29 



4 Sand volume for beach cross sections from 30 meters 



in front of dunes to 58 meters across the dunes 30 



5 Base width of measured dunes in 1981. Measurements show 



dune width between increasing elevations above 2.4 



meters MSL on the seaward side and decreasing 



elevations below 2.4 meters MSL on the landward 



side 32 



6 Distances from east base line to MSL for the study 



locations with beach cross-sectional profiles 35 



7 Sand volume for beach and foredune cross sections of 



existing naturally formed dunes 37 



8 Importance values (IV) for common species (planted and 



invading) for experimental foredunes for 1975, 1976, 



and 1981. Values are the mean of seaward and 



landward transects except the last two columns show 



differences between species establishing on exposed 



and protected dunes 39 



9 The percent of coverage for all vegetation for transects 



measured for various locations in the five study 



areas for 1975, 1976, and 1981 ". 41 



10 Importance values (IV) for common species becoming 



established within 69 meters of the planted dunes 



(landward) for 1975, 1976, and 1981 42 



11 Importance values (IV) for plants occurring on a 



midisland area, recently vacated by a migrating 



bare dune field 47
