25. Total Man-Hours. As an example, determine total man-hours 

 required to harvest, prepare, and plant 25,000 PUs of shoalgrass from sod 

 samples. Planting units were attached to anchors and wading workers were 

 used. 



Man-hours 

 Harvest (25,000 PUs ^ 3,000 PUs/man-hour) 8.3 



Attaching anchors (25,000 PUs v 100 PUs/man-hour) 250.0 



Planting (25.000 PUs -^ 150 PUs/man-hour) 166.7 



TOTAL 425.0 



' 26. This estimate includes only onsite work; it does not include 

 travel, gear preparation, or additional requirements for safety of workers 

 and equipment. 



Summary 



27. The planting techniques recommended in this report make use of 

 mature vegetative plant material that can be acquired with (sod) or without 

 (aerial runners) impact to the donor site. Based on the estimated man-hour 

 requirements for each collection technique reported herein, a cost-benefit 

 analysis with regard for the impact to the donor site could be completed. 



28. Cost estimates must account for the attachment of anchors in 

 moderate- to high-current areas, as well as consideration of shallow water 

 versus SCUBA-assisted planting. 



29. Material requirements are estimated by accounting for the 

 species selected, the species growth rate, and the area to be covered. 

 Formulas are provided for simplified computation of spacing of planting 

 units to achieve coverage within the desired time period.
