Results for March Madness for Conifers

Here are the results of the March Madness for Conifer trees across Lanark County.
Total observations for March were 153 conifer trees.
A total of 11 conifer tree species were observed.

In terms of size, here are the stats for the month:
Eastern Hemlock = 98.5 cm diameter (denisag2).

  • That’s 93% of one recorded at 105.4 cm in Ontario.
White Spruce = 66.7 cm diameter (sylviamiller).
  • That’s 84% of one recorded at 79 cm in Ontario.
Balsam Fir = 40 cm diameter (denisag2).
  • That’s 85% of one recorded at 47 cm in Ontario.
Eastern White Pine = 113.2 cm diameter (sylviamiller).
  • That’s only 66% of one recorded at 172 cm in Ontario.
Eastern White Cedar = 64.5 cm diameter (denisag2).
  • That’s only 36% of one recorded at 178 cm in Ontario.
Tamarack = 50.8 cm diameter (sylviamiller).
  • That’s 76% of one recorded at 67 cm in Ontario.

Red Pine = 50.2 cm diameter (sylviamiller).
Jack Pine = 32.4 cm diameter (sylviamiller).

The observation breakdown for the month by species was:
48 Eastern White Cedars
33 Eastern White Pines
23 White Spruces
10 Eastern Hemlocks
9 Red Pines
9 Balsam Firs
8 Common Junipers
5 Tamaracks
3 Jack Pines
3 Norway Spruces
1 Scots Pine

A big Thank You to Owen Clarkin for inspiring MVFN to look more at all the trees around us and for all the tree IDs on the March conifer project!

Thanks to all for participating, Happy Spring, and keep posting to iNaturalist!

FYI - Ontario’s Old-Growth Forests

Here's an interesting Internet site (by Michael Henry) that may interest you on Ontario's old growth forest. The web site also highlights some of Ontario's oldest and biggest trees.

Michael Henry is a forest ecologist who focuses on conservation of old growth forests, including threats from invasive species, development and logging. Michael has spent over two decades studying and working to conserve Ontario’s old-growth forests.

Also, here's a tree ID presentation from the Eastern Ontario Model Forest (EOMF) organization for the trees of Ontario. The presentation is well organized and comprehensive.

March Madness - A Conifer Countdown!

Inspired by Owen Clarkin’s presentation, MVFN is launching a hunt for conifers. Owen has agreed to be the resident "expert" on iNaturalist to confirm any observations made in March.

We are lucky to have at least ten native conifer trees in Lanark. They are easy to find in the winter. So when you are out and about keep your eyes peeled and see if you can find all 10 conifers.

The species are: Eastern White Pine, Red Pine, Jack Pine, White Spruce, Black Spruce, Eastern Hemlock, Easter White Cedar, Tamarack, Balsam Fir and the common Juniper.

When you locate one of the conifers on the list take a few photos of the tree (also it’s needles, cones and bark) using your cell phone or a digital camera and upload it to our iNaturalist project. It will also be fun to see where the largest of each species is in the county. When you find one: measure the circumference of the trunk at chest height using a string or cloth measuring tape. Enter your measurement in the note field.

The tallest tree in Ontario is currently a white pine in Arnprior that is 47 meters (154 feet) tall. Can we find one that is close to this?

Good Luck and have fun!

PS I've changed the filters on the MVFN Biodiversity project for the month of March to show only conifer trees. All your observations are still in the iNaturalist database, and will reappear in April.

2020 MVFN Project Summary

To review the overall citizen science contribution of the MVFN Lanark County Biodiversity project in 2020, I attempted to generate a summary report. The 2020 Project Summary report can be viewed or downloaded from the following link.

If you have any problem with this link, you can email me at

There is less nature variety to see over the winter months, but here are a few ideas for your nature outings (I'm sure there are others).

  • Conifer trees,
  • Animal tracks,
  • and your backyard-feeder birds, of course.

All the best in 2021 to You, Family and Nature!

iNaturalist webinar, from CFW

Discovering Nature: there’s an app for that!

Nature is all around us – throughout the city, in our greenspaces and in our backyards. Many Ottawa residents have been exploring their local natural areas and greenspaces this year and getting to know some of their wild neighbours. Camera phones and online resources such as enable residents to record, identify and learn more about the things they see. iNaturalist allows residents to contribute to conservation by compiling millions of observations across Canada and around the world. Researchers and naturalists can access this data to examine trends in wildlife sightings and occurrences. The information is useful for species at risk recovery and environmental impact assessment. Our speaker, James Pagé from the Canadian Wildlife Federation, will address how iNaturalist is helping people reconnect with nature, new Canadian discoveries, and whether nature has rebounded in a time of shutdowns and decreased human activity.

Join us online for this Zoom Meeting Thursday, November 19, 2020 at 7:00 pm.

For more information: Wildlife Speaker Series

Great time to get out

Thanks first of all to everyone who has contributed to the Lanark County Biodiversity Project.
We are now over 4800 observations and have 1532 species.

Many dragonfly, moth and bees/wasp observations are being reported. It's worth going onto iNaturalist just to see some great photos of insects you've never seen before.

We seem to have good numbers of some of the more southern species this summer with all the hot weather. We've had Slaty Skimmers and Blue Dashers (both dragonflies!) at our beaver pond over the past week.

Lots of plants are flowering now, too. The spring flowers we all love are done but the summer-flowering species are in full bloom and even some of the later species like goldenrods and asters are in bud, at least.

If you are interested in insects or plants, now is a great time to dust off your cameras and go out and look at all that's going on.

Happy Canada Day!

Hello everyone,

While Denis is basking in the sun in PEI, the rest of us can keep taking photos and submitting them to iNaturalist.

We're doing pretty well: we're up to 4232 observations and 1447 species for the county now. However, these have all been submitted by 29 observers.

For those of you who haven't tried iNaturalist yet, it's pretty easy and I encourage everyone with a smart phone or a camera to try it out.

If anyone can help with identification of any of the organism groups, we still have a fair number of observations that need identifications/confirmations. At least 2 people have to identify each observation before it is considered "research grade".

Anyway, keep up the good work!

Ken Allison

Great news for the Biodiversity project!

Ken Allison has graciously agreed to help admin and curate the MVFN Biodiversity project. I would like to thank Ken for all his nature postings throughout the spring project and for also taking the time to help others with their observations (e.g. ID-ing, etc.). Going forward, I’m sure Ken will continue to help members with their observations but we can also look forward to some interesting Journal posts to give us some perspective and highlights on the progress of the Lanark County Biodiversity project.

Keep posting and have a GREAT summer!

MVFN Spring project being renamed

Hi again, MVFN Lanark County Observers:

This is not the end, as of this week, the “MVFN Lanark County – Spring 2020” project is being renamed the “MVFN - Lanark County Biodiversity” project. This Biodiversity project will continue to capture all nature observations across Lanark County made by its MVFN members and friends. Note: The Date range is being removed from the project, so all your past observations will also get captured.

Recently, the MVFN Conservation and Habitat Committee launched a Turtle Watch project using the iNaturalist platform. So for all your turtle observations, please make your postings directly on the Turtle Watch project page. For any other taxa and species, you can post your observations to iNaturalist using the generic upload button, and your Lanark County observations will automatically be collected and shared in the MVFN Lanark County Biodiversity project. Note: Observations posted to MVFN Turtle Watch will also automatically show-up in the Lanark County Biodiversity project.

Keep observing nature and have fun sharing!
