Where do the bugs go in winter?

An interesting post on Northern Woodlands yesterday, How Insects Spend the Winter. I knew some of this but learned much more… adds to the perspective as I trundle through the snow-covered forest. By the way, have you noticed the days getting a bit longer?? Yes, spring (and the insects’ return) is coming! Between being a weather geek and being a solar-powered off-gridder I have a bit of an obsession with daylight hours and created a dataset to graph the day length pattern… you will see that now we’re beyond 4 weeks post-solstice day length begins accelerating 🙂

Why Woodpeckers Don’t get Stuck to Trees

I’m not sure I’ve ever asked myself this question, but when I read the headline, I needed to know the answer. Perhaps now you do too. Click the link to the article to find out, and there’s a short YouTube video as well. https://www.sciencemag.org/news/2021/01/video-reveals-why-woodpeckers-don-t-get-stuck-trees

European Gypsy Moth and Maple Syrup Production

European Gypsy Moth is an invasive forest pest that will feed on a number of different tree species including its preferred oak but also sugar maple, white pine and spruce. The numbers and sightings have been climbing over the past several years.

For those members who tap their maple trees for syrup the following article provides a good overview of the impacts of European Gypsy Moth on maple syrup production.

Friend of the BGWA Eric Davies speaks to the Weather Network about Norway Maple

I know that we’ve heard this before, in fact we’ve had Grey Bruce local Eric Davies speak about this topic to our group and at the Woodlot conference, however it’s a message worth repeating. The issue with Norway Maple is definitely worse further south, however it’s not limited to the GTA. I’ve seen these trees popping up in local woodlots, and therefore what Eric is showcasing may be a glimpse at the future of some of our forests in the absence of intervention.

Check out The Weather Networks interview with Eric right here.

Forest drones and satellite tree mapping

If you’re interested in both trees and technology, here’s a couple fascinating articles on how we are getting to better understand the makeup of the world’s forest cover:

An analysis of satellite images has pinpointed individual tree canopies over a large area of West Africa. The data suggest that it will soon be possible, with certain limitations, to map the location and size of every tree worldwide. Read full article.

Using robotic tools to automate forestry and reduce risk for human workers, Treeswift uses swarms of autonomous, flying robots equipped with LiDAR sensors to monitor, inventory, and map timberland. The drones collect images of the land and render them into 3-D maps that can be analyzed for precise, quantifiable measurements of a given forest’s biomass. Read full article.

Tree Marking Workshop Saturday October 17th, 2020

The intention of tree marking and its associated silvicultural practices is to create a healthier forest, which is fundamental to sustainable forest management. If you’re interested in developing a familiarization with the tools and techniques used by professional tree markers, you should consider attending our next BGWA Workshop on Saturday October 17th. Pre-registration is required, and the sign-up information is available right HERE (or on the BGWA website homepage under the “Tree Marking Workshop” tab on the top right). Join us for some (freshly sanitized) hands on learning and (socially distanced) discussions led by BGWA board members and local forestry professionals.

Today is National Tree Day

National Tree Day, September 23rd, is a celebration of the benefits trees provide like clean air, food, shelter, and most importantly, a connection to nature. Take a moment to step outside and express gratitude to the trees in your area or neighbourhood. In honour of Tree Day, the folks behind the documentary movie Call of the Forest are making the film free to view on Vimeo for the entire day.
