Title: Tree Species Diversity


1
Tree Species Diversity
  • Cameron and Rachael
  • Introduction to Local Biomes
  • Module 2

2
Introduction
  • Rain forests are unquestionably among the most
    intricate, sensitive, endangered and unknown
    ecosystems on Earth
  • This study consists of the familiarization with
    the local ecology by mapping the different number
    of trees within certain areas.

3
Introduction (continued)
  • Factors that provide the structure of a local
    biome are either biotic or abiotic.
  • Abiotic factors can be rainfall, slope and
    topography
  • Biotic factors may be such things as the presence
    of an animal species that contributes to
    dispersal or absence of a predator species.
  • Another important factor in the composition of
    the biodiversity is area. Larger areas will have
    more species.

Methodology
  • Standard for tree measurements was a height of
    1.35m and a circumference of 15cm.
  • Plots were created with areas of 5 x 5m, 5 x
    10m, 10 x 10m, 10 X 20m, and 20 x 20m.
  • The first plot studied was smallest (5 x 5m) and
    then with respect to increasing area with the
    largest plot (20 x 20m).
  • For each plot the morphospecies was noted as well
    as the number of each of those specific trees
  • Descriptions were made for each tree species found

Discussion
  • All sites experienced generally the same abiotic
    conditions. These conditions should have similar
    effects on biodiversity
  • From these results, it was seen that tree species
    diversity generally increases as the area is
    increased.
  • However, the species area curve graphs suggests
    that there is a limit to species diversity.
