Thanks for sensitive management of an old forest in Nova Scotia

A few photos from the  Conform Limited/NSWOOA field day (Oct 6) on “Harvesting the Old-Fashioned Way: Smaller Machines and Bigger Trees” say a lot  about Conform’s and the woodlot owner’s efforts to harvest selectively in a mixed, multi-aged “overmature” stand with as little disruption of the ecological integrity as is probably possible today, short of horse-logging in winter:

The site in Central NS hosts many 2ft+ dbh red spruce, hemlock and yellow birch, some red maple and occasional sugar maple and ash.

Trees are cut with a chain saw

and moved out with a mini forwarder (a Bison 10000).

Slash is placed over access routes to lessen impact of the light machinery

All of which, together with a lot more critical thinking about what to cut and what to leave, conserves most of the ecological integrity of this forest stand.

I was very interested to see many “pits and mounds” in the forest (top left) indicating a long history of not being harvesting intensively. Their orientation, and the maximum age of trees at this site (about 140 years) are similar to those I have observed in the area of Sandy Lake (Bedford) and suggest a similar history of old forests and winds. On the mounds, I observed more instances of   the “Acadian Forest Love Affair” between yellow birch and hemlock (top right).

A curiosity: Highly “stilted” or elevated yellow birches (left photo and right trees in the photo at right). There was porcupine scat in the space between roots of the yB at left (I didn’t inspect the right one)

My explanation (hypothesis): the highly stilted yellow birches got established on top of the uprooted bases of  large hemlock tip-overs soon after the tip-overs, as in the photo at right (taken at another site)…so the large roots enclosed, rather than were enclosed by, the mound that formed subsequently. The tip-over at right is a hemlock, approximately 26 inches dbh (diameter at breast height), and was still living, the yellow birch about 3 years old.

There are many stories to be told by these old forests.

————————-

Conform said they were not going to sugar coat what they are doing at this site, and they didn’t. There are many challenges, and certainly added expenses, to this type of approach.

Thanks for the old forest and thanks for sensitive management of it.

But it offers an option that perhaps many private woodlot owners in NS who want to conduct modest harvests while maintaining the ecological integrity of similar “over mature” stands (many of which would qualify as Old Growth)  would consider*. I had invited a close relative who falls in that category to come with me to the event, which he did and he his teenage son came with him. We all appreciated what we saw and learned.

Thanks woodlot owner C.C., Conform, and NSWOOA. It was especially appropriate to see this site and efforts on Thanksgiving weekend.
