[CANUFNET] Inquiry regarding tree size and tree establishment

[Naomi Zurcher]

I would like to clarify that you are suggesting planting trees with a smaller caliper rather than planting trees that are smaller when mature. It is important to make this distinction as large canopy trees, grown well into maturity are essential for the Ecosystem Services deliverable as well as the array of diversity they host.

Thanks for confirming.

I have many examples where small planted trees have survived and even surpassed the growth of nearby larger planted trees, if this makes sense.
