Our upcoming talk was identified as a “Must Learn” opportunity in the most the recent issue of “IN THE HILLS” magazine.
You can’t live in Headwaters without having an opinion about deer. You worry about them crossing the road. You love seeing them run across open fields. Or maybe you fret about your gardens or farmland – aka your local deer family’s favourite salad bar – and wonder when hunting season begins.
If you’d like to learn more about the species we share our space with, head to the Upper Credit Field Naturalists speaker’s night on Tuesday, March 29 for Deer Biology and Management in the Headwaters Region. Biologist Graham Findlay from the Ministry of Natural Resources and Forestry will share the basics on the creatures and what goes into managing them in our area. The talk is free and takes place at the Orangeville Seniors’ Centre at 7:30 p.m. uppercreditfieldnaturalists.org
Our favourite picks for Spring 2016
Bring your – skulls, minerals, fungi an so on for the nature nugget table, books for the nature book exchange table, samples that you want to view with the microscopes that will be available. If you haven’t already sent in images or reserved a table for a display there is still time to do so. Contact Ron Jasiuk at email@example.com
The Letter “P X 3” – Can you name the “P” creatures?
The first “P” has chewed the bark off of at least 57 Red Pine tress in a small area of the Alton Grange. Interesting that numerous Hemlock and scattered deciduous saplings were untouched except for one sapling.
The second “P” was calling throughout the Hockley Valley Nature Preserve. This very large excavation was found this past Monday before the snow arrived.
The third “P” at least 36 of them took over our bird feeders once the temperatures dropped accompanied by the falling snow.
A word that I have not uttered or thought about for probably thirty years popped into my head when looking at this picture of …….Lenticels. Although I was able to associate the word with the horizontal lines found on the Birch tree trunk I remembered nothing about the structure or function of Lenticels.
“Raised circular, for sale oval or elongated areas on stems and roots are known as lenticels.” After reading this I saw lenticels everywhere..on my carrots, beets, apples, potatoes and houseplants.
Lenticels function as pores to allow for the exchange of gases. It’s how tissues within stems, trunks and roots get oxygen.
For some tree species such as the Pignut Hickory and Northern Spicebush, the shape of the lenticels can help with winter identification.

On Tuesday Jan. 26th, Phil Bird from the CVC will be giving an illustrated talk about some of the unique fishes found in the Credit River watershed.
Presentation will start at 7:30pm at the Orangeville & District Seniors Centre, 26th Bythia Street, Orangeville.
Did you know that all of the fishes shown below are found in the Credit River?
WHAT’S BETTER THAN AN “ELF ON THE SHELF”?
HOW ABOUT AN “ERMINE EATING YOUR VERMIN.”
Orangeville residents Kirsten and Carmen Plester have a weasel living in their garage. Kirsten managed to photograph the very curious and seemingly unafraid weasel with her cell phone. The Plesters suspect that this little carnivore has been feeding on mice and Chipmunks.
They’re hoping to get another look at it in order to determine whether it is a Long-tailed Weasel, a Short-tailed Weasel or a Least Weasel.
It was surprising to find that the best sources of information about these three species of weasel was from websites geared towards fur trappers such as this http://www.env.gov.bc.ca/…/wildlife/trapping/docs/weasel.pdf and http://www.furmanagers.com/#!weasel/czxh
FYI: In a 2012 article on Least Weasels by Gilbert PROULX in Canadian Wildlife and Biology Management said “The Least Weasel (Mustela nivalis) is the smallest carnivore of Canada….no ecological studies were conducted on this species….The absence of field work on the Least Weasel in Canada….I argue that the lack of interest in Least Weasel research is due to its body size and elusive behavior, its difficulty to study, and its poor economic value.”
Once again it’s surprising to realize how little we know about a “common?” species.
