Improving tree health by engaging people in hands-on tree care and inspiring a new generation of environmental stewards.

Few better ways to start a Monday than by learning about the parasites that create some oak galls, and the parasites that parasitize those parasites.

Great work! Spotted lanternfly is a skilled hitchhiker - it can show up anywhere if it gets a lift. People keeping their eye out for strange bugs can help prevent the spread of invasives like SLF!

@MikeTreglia I think I'm going to go with tonnage, just so the measurement is completely unrelated but sounds related

This is so cool!

This trunk of an oak tree serves as a nest of an albar pine. Both trees are alive and have been sharing living space for more than a century. The pine reaches 15 meters high and is 130 years old, while the oak measures 12.5 meters and is 250 years old.

Located in Burgos, Spain

It’s the first day of #fall and this horse-chestnut is #done. (Is otherwise an apparently healthy tree). Seems a bit early! But who am I to judge?

Mapping out hot spots in cities defines where trees are needed the most.

I think I prefer 'Squish' to 'Squash' but the message is the same.

#SpottedLanternfly has quickly become a well-known #invasive insect, due to it's quick spread and wide host range. Fall is when they lay their eggs and experts have info for you to help stop their spread. https://t.co/QIn3PzmUIx Pic: Richard Gardner, https://t.co/llX9a0PciG

Good news! Naturally occurring fungi – Batkoa major and Beauveria bassiana – found in soil in forests may control spotted lanternfly!

Penn State scientists may have discovered way to control invasive spotted lanternfly https://t.co/auV3RMHJHz

@HealthyTreesHC has been working with @Nature_KY to record and study tree health in Louisville. Great article on the importance of urban trees and the Green Heart project!

If we know how healthy our trees are we can intervene to help them before they disappear. Bigger healthier trees will provide more cooling. @HealthyTreesHC

Although #Asianlonghornedbeetle was recently overshadowed by more threatening invasive insects, new research reveals larvae have a broader range of host trees than adults, quietly aiding its spread.

Exciting results this week! This healthy green ash seedling mounted a defense response that killed over 90 % of the #EAB larvae that entered it. Parents of the seedling are #lingeringash trees that survived long term EAB infestation. #treebreeding works!

Beer lovers - you should be worried about #spottedlanternfly too!

[Heather Leach @heatherleach_]

Spotted lanternfly found feeding on hops today...but only 2! So far, they seem to prefer grapes.

tfw a train interrupts your TRAINing. Still loving #Boise - what a beautiful park to work in today!

[HTHC @HealthyTreesHC]

Training some great partners out in Boise today in a beautiful spot- lots of great trees around too! Thanks @TVCanopy and @Nature_ID !
