• Abstract:
   In an attempt to combat the issue of NPS pollution, EPA has started to enforce different 
  
  areas of the Clean Water Act of 1972 by requiring construction sites to have 70% vegetative cover in 
  
  30 days.  The main goal of this research is to identify mixes of warm and cool‐season plants that 
  
  establish quickly.  A secondary objective is to identify those species that provide good quality and 
  
  dense cover that will require minimal maintenance while stabilizing disturbed soils.  One question that 
  
  must be answered is 30 days from planting or first significant rainfall.  Among warm season species 
  
  bermudagrass and bahiagrass were found to establish well but failed to reach 70% cover in 30 days.  
  
  Among cool season species turf type tall fescue was one perennial specie that established well but not 
  
  rapidly enough, its height remained less than 100 mm for much of the growing season and never 
  
  exceeded 100 cm.  Oil seed radish showed great promise as a year around nurse crop that established 
  
  quickly.  Sods of hybrid bermudagrass, zoysiagrass, and centipedegrass all provided instant cover that 
  
  has lasted more than 2 years
