Description

  • This study evaluated the growth and survival of four native tree species planted as seedlings in grassland (the grass had invaded previously abandoned tea plantations).
  • Forty-eight individuals of each species at various sites along a gradient of grassland, grassland/forest edge, and forest. 
  • Each seedling underwent one of eight different treatments based the various combinations of: with or without root competition, shoot competition, and vertebrate herbivory. Seedlings that died within the first month were replaced. 
  • Growth and survival was evaluated at 18 and 28 months. 
  • The authors found that root competition was a more significant constraint on seedling growth and survival than above-ground competition and herbivory. 
  • Three of the species, Macaranga indica, Schygium spathulatum, and Symplocos cohinchinensis showed positive growth responses to reduced root competition while just the fast-growing light demanding species, Macaranga indica, had higher survival upon the removal of root competition.
  • Symplocos cochinchinensis had the highest growth and survival with and without root competition. 
  • The authors suggest that intensive site preparation to reduce the root competition might be necessary for restoration of these species in the grassland.
  • Additionally, they recommend that the Macaranga and Sympolocus species would be the most promising for native species reforestation in the grasslands.
