Georgia River Park Project: STEM Cohort Ecosystem Measurements and Findings

The Georgia River Park Project involved the HCHS STEM cohort measuring and analyzing the local ecosystem. The team marked off 1,000 square yards, dividing it into six sections for biodiversity and tree counting. Biodiversity collectors identified species like snakes, box turtles, and various birds to assess ecosystem balance. Tree counters found dominant species in their area, including Birch, Oak, and American Holly, with calculated estimates for the entire forest. Additionally, water quality was tested, revealing neutral pH and no harmful nitrogen or iron levels. Find out more about our findings!

Presentation Transcript

  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
