Trees grow with, and adjust to, large lateral and vertical loads caused by wind and gravity. Storms with strong winds and ice can push trees beyond their ability to reconfigure or fall back to reduce drag.
Trees constitute the foundation of our natural ecosystems and contribute considerable value to the economy.
With increased intensification in cities throughout the world, urban trees are often at risk of becoming damaged by construction impacts, such as utility trenching or pavement / sidewalk repair.
Across the country, a number of cities are setting ambitious tree canopy goals to fight the trend of a decline in tree canopy.
This document was developed as a contribution to “mainstreaming biodiversity
into agriculture, forestry and fisheries”, as recommended at the 24th Session of the
The results of 14 years of monitoring ash mortality and forest ecosystems in Ohio and Pennsylvania show how EAB has impacted these landscapes.
We will explore how researchers from ecology, forestry and arboriculture have utilized biomechanics to understand how trees contend with the forces mother nature can throw at them during their long-life span.
Tree planting can help communities achieve many resiliency goals such as cooling heat islands, reducing stormwater floods, and building neighborhood cohesion.
Tree health and risk is heavily influenced by the health and quality of the soil surrounding it.
Ash tree species in North America are under mortal threat from the Emerald Ash Borer (EAB), now in 35 states and five Canadian provinces.
