Here’s what it looks like on one of our Hemlock trees.
Of note is that Finzi, et al (2020) found that the Hemlock subforest of the Harvard Forest Long-Term Ecological Research site became a CO2 source rather than a CO2 after its Adelges infestation.
NEP in hemlock-dominated forests averaged until infestation by the hemlock [W]oolly [A]delgid turned these stands into a net C source.

Want to save New England forests? Stop emitting CO2 and build solar farms, even if there’s some forest loss! And harm to forests isn’t the only byproduct. People spray Hemlocks to control this beastie, and the solutions are not good for wetlands.
