ABSTRACT:

The objectives of this effort were to characterize species presence, cover, and biomass for herbs, shrubs, and tree regeneration, and to quantify tree regeneration by species and size class. The proposed scheme includes the following elements:

  1. cover of shrubs and tree regeneration
  2. herb cover
  3. biomass of erect shrubs
  4. tree seedlings and saplings
  5. Compile a complete species list of vascular plants
