  1. Georgia river Park project Stem Cohort HCHS STEM Cohort

  2. Measurements • Began by measuring off 1000 square yds • Measured off 33 yds x 33 yds • Marked off corners of 6 sections for tree counters

  3. Biodiversity • Biodiversity collectors went in forest to decide if ecosystem was balanced • Snake holes, box turtle, fox den, raccoon footprints, scat, and various birds and insects were found

  4. Tree Counting • Tree counters went into forest to find most dominant tree species • Three most dominant were Birch, American Holly, and Oak

  5. Dominant Tree Species In 1,000 yd2 we found: 64 Birch Trees 49Oak Trees 49 American Holly Calculated total number of trees in the forest. (4,840*412)/1,000)*# of each tree= total of that tree in the whole forest In 1,994,080 yd2 (412 acres - entire forest) 127,621 Birch Trees 97,709 Oak Trees 97,709 American Holly Total number of dominant trees in 1,000 yd2 Total number of dominant trees in 1,994,080 yd2

  6. Watertesting • Some students tested different water qualities • pH was almost neutral and no nitrogen or iron was found

  7. Results • Tree counters came together and discussed findings • Biodiversity collectors gathered and shared data • In the following videos, final data was shared with entire STEM group
