Arbor Day 2020

Last year’s Arbor Day event at Boys Scout Camp in Baiting Hollow was a fantastic success. The teamwork and camaraderie exhibited that day is commendable. Everything they requested was completed and they were very pleased with the work that was performed and grateful for our contribution. Great Job by everyone!

For our 2020 Arbor Day event, the LIAA will be at Planting Fields Arboretum State Historic Park in Oyster Bay on March 28^th, 2020. Our focus will be on safety pruning, structural pruning and hand pruning, as well as some tree removals.

Arbor Day Event at Planting Fields Arboretum in Oyster Bay has been postponed.

We will keep you posted on the exact date
