Abstract
  • A map of the distribution of the fauna, the flora
    and their relationship with the abiotic
    parameters was done in a forest ecosystem. An 10
    m2 area was chosen and 1 m2 grid was done. Air
    and soil temperature, soil moisture and air
    moisture were noted. Animals were registered with
    the aid of 10 pitfalls and manual collecting.
    Trees were identified and the vegetation cover
    noted at the collection site. The air temperature
    ranged between 29.0 and 29.5OC, the soil one from
    22.0 to 24.0OC. Parts of the soil were wet and
    others dry. A total of 18 invertebrate and four
    tree species were identified. The soil was
    covered by litter, vine or bare in different
    levels of thickness. In a general way, animals
    were present in covered area. These data were not
    enough for understanding the terrestrial
    ecosystem, but they sufficient to map a small
    area using GIS program.

Objectives
  • Map a small terrestrial ecosystem using the GIS
    program.
  • Identify animals and plants and do correlations
    with abiotic parameters.

4
Questions to be answered
  • How oscillate the air temperature, the soil
    temperature, soil texture and moisture ?
  • What animal and plant species are in this
    ecosystem ?
  • What is the relationship between communities and
    abiotic parameters ?

5
Methods
  • A 10m2 area was chosen and a 1m2 grid was done.
  • The following abiotic parameters were measured
    air and soil temperature, soil texture and
    moisture.
  • Animals were collected with the aid of pitfall
    traps. Also, the ground cover was searched to
    register the soil animals.
  • Vegetation cover was searched.
  • Tree species were identified.
  • GIS and ArcView were used to map the distribution
    of living beings.

Results

Conclusion
  • GIS is a powerful tool for mapping and doing
    correlation between biotic and abiotic
    parameters.
