Overview
A tree that you can not miss due to how large it is, is the Black Oak. This is the largest tree we will cover so far on your Quests.
The Black Oak stands at a massive 20 meters tall and has a trunk diameter of 90 cm.
This dwarfing tree is one of the most important trees in an ecosystem due to the multiple benefits it brings to the ecosystem.
This tree not only flowers in the early spring but also produces acorns in early June and September.
With all of this production– it allows various animals to feed such as pollinator insects, deer and wild turkeys.
Habitat
In Ontario, the black Oak is at its most northern limit due to its inability to deal with cold weather conditions.
This tree requires either chalky sand-like soil or well-drained acidic soil.
It also requires large spaces to grow to full size- uninterrupted.
Here in Ontario, we have a well-maintained Black Oak Savannah which is widely spaced out between Oak Trees that dot the landscape.
The best way to maintain these landscapes is through controlled burns which allow for the land to open up and for the Black Oaks to get more nutrients from the dead plant matter.

Threats
Black Oaks are at the most northern limit here in southern Ontario. The biggest threat to them here is the continual climate change.
By having more severe winters here, our local populations are continually challenged each year to thrive.
This can cause stress in the tree and make it less likely to return next season as a healthy/alive tree.
It also weakens the tree, leaving it vulnerable to disease, viruses and pests.
