20. Figure 3 and A illustrate the development of a shoalgrass 

 planting unit from transplant to 160 days' growth. 



Labor Requirements 



21. Labor rates for the three phases of planting are discussed 

 below. 



22. Harvesting and preparation of planting units , 

 a^. Aerial runners. 



(1) Shoalgrass - 500 aerial runners or planting units 

 per man-hour. 



(2) Manatee grass - 325 aerial runners or planting units 

 per man-hour. 



b^. Sods . 



For either species, 18,000 shoots or 3,000 planting units 

 per man-hour. 



23. Anchor Attachment. If planting units are to be attached to 

 anchors, labor rate is 100 PUs per man-hour. 



24. Planting. 



a. Planting rate for wading, non-SCUBA assisted workers is 



about 150 PUs per man-hour in most habitats. 



b^. Planting rate for SCUBA-assisted workers is about 175 PUs 



per man-hour. (Note: although SCUBA-assisted workers are 

 at least 15 percent faster than non-SCUBA assisted 



workers, wage difference has always resulted in non-SCUBA 



workers being most economical when conditions permit.)
