Tree ID in Muskoka


It's that time of year again! The Nature Quest Stewardship Series is in full swing. Join us every Tuesday in July as we learn about tree identification, species at risk, bats, and forest management.


Participants look in their field guides and they identify a tree as part of the first Nature Quest workshop of the summer.



This week, the topic for the workshop was "Hike up your tree ID IQ". You might remember a workshop with the same title from last year. The new Stewardship Coordinator at the Parry Sound Muskoka Stewardship Council, Chris Near, refreshed the program this year and enthralled the audience in an afternoon hike at the Bracebridge Resource Management Centre.

Chris helped to give us the tools we need to become tree ID experts. Here he helps a young participant identify some needles from a coniferous tree.


Chris helps some of the participants note the differences between the leaves of hard and soft maples.



We started off with a list of ways that trees can be identified:



Coniferous or Deciduous

Coniferous are cone-bearing and have needles. Deciduous have leaves.


Bark

What colour is it? Is it rough or smooth? Does it peel? Is it hard or soft? Each tree has a distinctive bark. This is a good way to identify deciduous trees in the winter.


Leaf Pattern and Structure

Are the leaves compound or are they simple?

Do the leaves grow opposite on each side of the stem or do they alternate?
Along the edges, is each leaf lobed, single toothed, or double toothed?

What is the shape of the leaf?

When there are no leaves on the trees, it can also be helpful to look at the pattern of the buds on the branch.



Needle Pattern

Are the needles clustered together? if so, in groups of how many? Or, are the needles single shoots off the stem?

Silhouette

What is the silhouette of the tree when you stand back a little but and look at it? Round, pointy, bushy? This can offer a hint as to the species of the tree.



Fruit

Is the tree bearing any fruit? What does it look like? What shape is it?



My list above is very brief and uses only words. It's a good idea to find a field guide to help you with your tree ID. There are also some good websites to help you along. Some suggestions are at the end of the blog. It's also a good idea to go for hikes to practice your tree ID. After all, practice makes perfect! Good Luck!




Participants walk along the trail and the Bracebridge Resource Management Centre. It was a beautiful day for a hike as we identified trees.

Hike Up Your Tree I.D. IQ

How is your tree I.D?

I brushed up on my tree I.D. yesterday as I attended the first Nature Quest workshop of the summer, along with a few of the Master Stewards. The workshop was hosted by Mike Walsh, Tree Marker Instructor and retired Stewardship Coordinator for the Parry Sound Muskoka Stewardship Network.

Together, the group walked through the unmanaged forest of Arrowhead Provincial Park examining the trees for species, defects, potential growing stock, cavities and mast. We examined 25 trees in total; each tree giving us different insight into its value in a managed forest situation.

My favourite are the trees that are ideal cavity trees. Cavities are little nooks or holes where an animal has dug or burrowed into a tree. Cavities are used as habitat or places to escape bad weather or predators. Cavity trees have a high wildlife value and tree markers recommend leaving 6 cavity trees per hectare in your forest where the tree is at least 25 cm DBH (Diametre Breast Height).

The best kind of cavity tree is called C1. These trees are at least 25 cm DBH and have one of the following:

  • Pileated woodpecker nest cavities
  • Pileated woodpecker roost cavities
  • Swift roost cavities
  • Other woodpecker nest cavities
  • Natural nest or den cavities

The next best, or a fair cavity tree, also is at least 25 cm DBH and has one of the following:

  • Escape cavities
  • Feeding cavities on the bole or major branches


We also learnt about common tree diseases in Ontario like black bark, punk knots, spine tooth fungus, frost cracks, and sugar maple borer. Some trees are able to heal themselves from the diseases and can still be valuable to a forest. Other diseases have air borne spores and can infect neighbouring trees so it is best to cut them down.

I have lots of information and pictures about tree defects and forest management at the office. Of course, the Resources section of the blog is also a good place to start. Contact me or check it out!

Learn more about cavities on the Ontario Woodlot Association website.

Didn't make it out yesterday? There are more workshops in the series! Check out the blog posting from June 23rd called "Nature Quest Stewardship Series" for more information.
