Abstract:
This study aimed to reveal indicator plant species in secondary forest through applying descriptive approach and field observation as well as refer to releve method. From the results noted several vegetation data of vascular plant at seedlings, saplings, poles, and tree stages that analyzed using MVA.4 (TWINSPAN) software. The analyzed result indicated 12 group of associations and 1 group of solitary association in which the species were categorized as dominant. The most often appear species in 12 association group based on their growing shapes were Actinodaphne nitida, Celtis latifolia, Hemappasandra sp., Teijmaniodendron sp., Lea acuelata, Spatiostemon jevensis, Koordersiodendron pinnatum, Sisipus sp., Sterculia macrophylla, Litsea timoriana, Macaranga sp., Aglaia sp., Rhus taitensis, Alstonia scholaris, Archidendron parviflorum, Callophylum inophylum and Ficus sp. While the most dominant species in the solitary association were Chisocheton ceremicus, Cryptocarya sp., Canarium hirsutum, Euodia elleryana, Litsea ladermani, and Litsea timoriana. These species arranged and functioned as the dominant tree structure in secondary forest along North Manokwari area of Manokwari.
