Carbon Sequestration
Total carbon sequestered to date: over 80 kg Oakville Trafalgar H.S. and Appleby College sequestered 20.075kg and 19.62kg, respectivelyThis is significantly more than other schools (0-8kg)Environmental stewardship of site and initiative/effort are important to increasing carbon storage Slide2Slide3
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 recordedSlide4

Conclusions
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 storageWe 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 awarenessSlide8
Measuring Our ResourcesSlide9
Students measure and monitor the trees already located on their schoolyard grounds
Trees are tagged
and numberedMeasurements 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 databaseSlide10
Trees are numbered and tagged...Slide11
…and then growth measurements are taken
Height Measurement using clinometersSlide12
