Remarkably limited measures of carbon sequestration by native forests have been made in New Zealand. However, Tāne's Tree Trust (TTT) has produced its Carbon Calculator for Planted Native Forest based on the Trust's Indigenous Plantation Database (Bergin and Kimberley 2012).This database of measurements of planted native forest and shrubland is based around

2021-12-12If to enhance biodiversity you planted 10 trees/ha this would create beautiful parkland sequestrating 0.48 tonnes/ha/year. This means each tree reduces sequestration into the ground by 0.319 tonnes/year. A standard forest plantation has 2400 trees/ha, which equates to an extra 720 tonnes of CO2 left above ground /year for each ha of trees.

2022-01-15Capillary trapping is caused by the movement of CO 2 and water. When injected CO 2 displaces the formation water, the CO 2 saturation increases and water saturation decreases. As CO 2 migrates upwards, water flows downward. The wetting phase (water) enters the pores occupied by the non-wetting CO 2 phase.
