  1. Carbon Sequestration Total carbon sequestered to date: over 80 kg Oakville Trafalgar H.S. and Appleby College sequestered 20.075kg and 19.62kg, respectively This is significantly more than other schools (0-8kg) Environmental stewardship of site and initiative/effort are important to increasing carbon storage

  2. Health • Tree loss due to mortality or tree removal from site was 4% • Majority of trees are healthy/alive • Low browsing, sick/infested, dead/ dying, basal sprouting percentages were recorded

  3. Average change in crown area (m2) for P4C tree species planted 2008

  5. Tree canopy cover for mature tree species in P4C program

  6. More long-term monitoring plots should be established so that trends may be studied and to see if results are replicated • Environmental stewardship may significantly increase growth of trees which significantly increases carbon storage • We can study climate change impacts on trees and provide valuable environmental education at the same time • Young citizen scientists’ data is important and P4C helps to spread environmental awareness Conclusions

  7. Measuring Our Resources

  8. Students measure and monitor the trees already located on their schoolyard grounds • Trees are tagged and numbered • Measurements taken include height, DBH, and crown width. Tree health is also assessed and tree species are identified • Students create a sketch map of the trees that were measured • Data is inputted into database

  9. Trees are numbered and tagged...

  10. …and then growth measurements are taken Height Measurement using clinometers

  11. Tree ID and Health Status STATUS CODE A: Alive B: Dead S: Standing L: Leaning P: Prone HEALTH CODE Mechanical Damage NN: None BD: Bark Damage TB: Significant Top Breakage RD: Visible Root Damage CG: Complete Girding Defects NN: None DV: Minor Damage/Vandalism AB: Animal Browsing II: Insect Infestation SD: Symptom of Disease
