EVIDENCE SUGGESTS THAT PRODUCTION OF CARBON DIOXIDE AND METHANE FROM HUMAN ACTIVITIES HAS ALREADY BEGUN TO CHANGE THE CLIMATE, AND THAT RADICAL STEPS MUST BE TAKEN TO HALT ANY FURTHER CHANGE

[Frederick W. Schueler]

Everyone,

Seeing "Seniors for climate Action" tootled in the news, I sent a poem
about climate action from 1989 to the North Grenville Times -

Schueler, Fred. 2024. Seniors for Climate Action. North Grenville Times
12(40):11, 10 Oct 2024 - https://ngtimes.ca/seniors-for-climate-action/
(reprints Sea Wind 5(1):4).

With our recent variety of problems and distractions, I never finished
the article about Himalayan Balsam, but continuing the series on
invasive plants, I'm now working towards one on Scots Pine and its
vulnerability to native North American nibblers (Porcupines, Pine
Sawflies, Pinewood Nematodes), so if anyone has stories about this
species invading or dying back, I'd be interested in seeing them.

For two years, I world with MNR’s Forest Health Unit. Don’t look it up, it was downsized out of existence around 2016. My job was to monitor the woodwasp that normally lives on Scots Pine - the European woodwasp, Sirex noctilio. They’d recently been found in Cornwall. We found them fully invested in every county south of the shield. Most of the highway 17 corridor too. 

The fear is that they get into the northern logging industry. The shield seems to be too cold to allow them to thrive, but they’re definitely moving north.

Hi Fred, We have a meadow full of small but cone-bearing Scotts Pines that originated with a 'live ball' Christmas tree that was planted in the late 80s. This tree died several years ago, but not before generating many dozens of offspring and new seedlings scattered about represent a third generation. None of the 2nd generation have ever gotten bigger than about 15 cm dbh before dying but they produce a lot of cones at a small size and young age. We haven't tried to control this population other than to harvest one each year for a Christmas tree. Another live root tree planted around the same time was a Norway Spruce that continues to grow, but more slowly and it has only seeded one offspring so far.

* that's very similar to what happened on our land along Bedell Road -
the Miles had one tree on their land (gone some time ago, I don't know
how), and seedlings showed up on our adjacent field, and have produced
third generation saplings, but have all died or died back at or below 15
cm DBH.

The Limerick Forest Scots Pine "seed orchard" at Limerick/Cooper roads -
https://karstaddailypaintings.blogspot.com/2012/03/limerick-scotch-pines-oil-on-canvas-16.html
- now has a number of dead and failing trees, and I suppose that before
I write anything I'd better push in through the Buckthorn and measure
some of them.

Hey Matt 

Go look for bored holes into the bark. You’ll find all sizes, but the ones about 3/16” or 4.78mm  are very likely bores from Sirex noctilio. 

Cheers

Steve
