The average amount of carbon stored in nursery or recently transplanted Juneberry, Apple, Pear, and Lilac cultivars was measured. Smaller trees (3.8-6.4 cm diameter at breast height) stored 0.3-1.0 kg carbon in the roots, and 1.7-3.6 kg in total. Larger trees (14.0-19.7 cm dbh) stored 10.4 kg+ in the roots, and 54.5 kg in total.

Juneberry – Amelenchier spp.
Apple – Malus spp.
Pear – Pyrus spp.
Lilac – Syringa spp.
