  • This report was a study of the survival of 12 native pioneer species and one exotic species when directly sown into grasslands (Themeda triandra and Imperata cylindrica grasses).  They were monitored for 16 weeks (see seedling survival percentages below next to species name).  Authors note that direct seeding studies are important because direct seeding is cheaper and faster than nursery propagation. 
  • The site had a dry season from Oct/Nov to April/May and poor soil.  Small seeds (<15mm) were sown at a depth of 2 cm, while larger seeds were sown at a depth of 3-4 cm; 25 or 50 seeds were sown per block with a total of 4 blocks in the experiment. 
  • The article discussed possible reasons for poor survival or no germination.  Table 2 lists economic uses of the 6 species with greatest survival.
