Tree identification is a perennial favorite webinar topic, and the recent webinar on conifers was no exception. Over 100 participants on January 20 learned about the ecology and identification of 10 common northeastern conifers. Key features were presented, but importantly the process of learning a systematic approach was emphasized.
The webinar is now archived on youtube here.
I recently wrote an article about the characteristics of several conifers genera (plural for genus). That appeared first in the NY Forest Owner magazine, January/February 2016. Visit here for previous issues. I have posted that here, the corrected version. I mistakenly reported that Carolina hemlock (Tsuga caroliniana) occurred in southern NY...it doesn't. conifers.NYFO.2016.January-February.erratum.pdf
There has been some good follow-up questions to the webinar, so I thought I would post a few pictures. I had a nice chance to grab a few specimens along Rt 3 in NNY near Cranberry Lake. Beautiful country if you have the chance to travel.
Picture 1. Red spruce (Picea rubens) on the left and black spruce (P. mariana) on the right. Red has longer needles, greater density of needles (though not always), darker green and more robust. The black spruce came from a bog, as you might expect, and has poorer growth.
Picture 2. Eastern larch (Larix laricina) showing the spurr shoots. Remember larch is deciduous.
Picture 3 - Balsam fir (Abies balsamea) foliage, showing the globose waxy buds.
Picture 4. A wet site dominated by eastern larch, balsam fir and black spruce. The color pattern on the upper crowns may be lighting at the end of the day. I don't recall crown damage when I took the picture.

The hemlocks in my woodlots have been infested with hemlock wooley adelgid (HWA) for at least three years now. Lately I've noticed some of them having a rust colored bark and I wonder if this is normal and that I just didn't notice it previously? …Continue

Question: In Peter Smallidge's most recent "Ask a Professional" column for NYFOA's Forest Owner magazine he stated that some log buyers will reject ash that shows outward signs of "blonding" on the bark. Is this because the wood will change…Continue
