The Forest for the Trees: Reflections on an Ecological Land Classification (ELC) Project

Looking back on my last semesters at Seneca College during the pandemic, a highlight that stands tall was our Ecological Land Classification project.

This is definitely something I would like to share with nature-lovers considering taking the environmental technician program, and I was lucky enough to conduct this project twice, once as a soils student, and once again as an ecology student.

While the second experience was was incomplete due to the pandemic, it did offer extra opportunity to tighten my grasp on concepts, be absorbed in the process, and reflect on the system's relevance. (And a slide doc to dump some of the photos I have accumulated from several visits to the college's King Campus --link to the final product is just below the last image in this post if you want to jump to the SlideDoc).

Ecosystems can be described as communities of living things that interact with each other as well as nonliving things in their environment. So this means it includes plants and critters and microorganisms, as well as the types of soil and how water drains through it.


There is an old saying that talks about being unable to "see the forest for the trees". While this proverb is usually used figuratively, it can be a literal difficulty in ecology.

Say you and I were naturalists that hiked through these two forests: one forest that is virtually all coniferous in the crisp, Yukon wilderness, and then a mostly deciduous forest in Southern Ontario. If we were asked to explain the difference between these two forests most of us would probably quickly point out that one is all hardy evergreens, and the other is not with trees that transforms the forest into a glowing orange world in autumn.

But what if we had to be more specific than this? 

Also, what if we were comparing two forested areas in Southern Ontario where the differences are not so obvious?

While describing forests more generally could be all a photography hobbyist needs, it may not suffice for a land use planner or ecologist.

In a case like this, we would have figure out what to focus on to allow a person to understand what characterizes a forest; what sets is apart from another forest from an ecological perspective. This can be important for land planning and conservation.

The ELC System

The Ecological Land Classification (ELC) system  is a method of putting different types of ecosystems into set categories. This way, instead of having two ecologists visiting the same place in nature and potentially focusing on different aspects of it, the ELC system provides a standard for identifying and communicating what type of ecosystem it is based on soil and vegetation.

For our assignment, we got a taste of parts of the Ecological Land Classification process, including on-site soil sampling at Seneca College's beautiful King Campus.

One slide from our final document. (See link in this post). If you are in the King City, Ontario area I'd definitely recommend visiting Seneca's King campus for hiking!

We made our observations by drilling into the ground with a hand auger to identify and measure soil layers (the deeper layers were quite dry so yes it takes some muscle work), and identifying and tallying up vegetation using a forester's prism to keep our observation method standardized. (If your curiosity about this is burning you can check out this video about it on youtube).

King Campus is not our program's primary campus, but it was always a little adventure to visit; it was a special treat to do this to dig into into the concepts examined for our ELC report firsthand, do some more research and group discussion, from home, and finally narrow it down to a "Dry-Fresh Sugar Maple Deciduous Forest" classification. Reflecting on potential implications for conservation of this unique old growth forest also gave it special meaning. While this could not be included in the report as it was slightly outside our polygon, on the way into King Campus I noticed tulip trees, unique to Carolinian Forests. I first learned about these trees from a Naturalist at the pinery, but perhaps the details of that memoir can be saved for another day.

It was also fun to go through old photos from King campus over the past couple years in the program, and be able to apply them to our final in-leu-of-presentation slide doc.

Without further ado, here is a link to view the PDF:*

I also truly enjoyed working with my group members on this assignment. Being able to dig into this subject -both literally and figuratively- with a group that is so passionate and curious about nature was a highlight of my time at Seneca College. In case you would like to connect with any of them, here are the LinkedIn pages of the co-authors of this assignment:

Additionally, if you liked the style of our document and might be interested in collaborating on something like this for professional purposes, feel free to contact me via LinkedIn above or the contact form at the bottom of this blog.

The calm of standing between the trees, and feeling of fulfilment that came from building this project is what motivates many students take Seneca's Environmental Technician course for. The method felt quite natural; letting it grow from its very basic roots of observing nature; looking at it and examining its details, touching it, naming it. Followed by recording what we learn, and then communicating that information in a way that is useful and potentially inspiring or beautiful to a particular audience with eyes open to see value. 

Many students may not end up working outdoors; there are many jobs that need to be filled in labs, offices, and community centers. But in either case, it was a great experience to be reminded of one aspect of what we are all working for.

Announcement Re 'Posts on Hold' Status Update, Semi-Hiatus

Hello everybody. I truly hope that all readers have been keeping well and safe, and have found ways to enjoy the turn of the season. 

Just wanted to post a little update as well as record of this announcement that has been up on Nature Nimbus these past several months:

Posts on Hold


Dear Reader:

Due to the COVID-19 pandemic, regular posting has been temporarily put on hold to allow more efforts to be directed towards volunteer response.

Thank you for your support, and thank you very much to those working in essential services.

As evident in the archives, this is one of Nature Nimbus' quietest years, and [edit] as of April 2021 I've decided to extend this hiatus. However, at this time I would like to re-emphasize a sincere thank you to those who have given their hard work and support, including moral support, throughout the year. It makes a difference.

Continue taking care,

Melody

Perseid Meteor Shower Peak August 11-13, Moon-Free View August 17

For a bit of light in the darkness, look up until August 24th to see the Perseid meteor shower (pronounced "per-see-id"). The peak is August 11-13, where there will be an average of 75 meteors passing overhead each hour. 

Earthsky.org highlights that while the peak understandably gets a lot of attention, because of the moonlight the best time to skywatch for this event might be August 17th, when there won't be moonlight outshining the meteors.

Also, just as with any skywatching event it can be ideal to make the most of clear skies whenever they avail themselves.

More of Earthsky.org's tips can be found here.

Happy skywatching ðŸŒ

Wear masks mindfully when it's hot and humid


A couple weeks ago the World Health Organization officially announced their recommendation to wear masks. That said, amoung other measures for safe mask use some experts have recommended that people carefully consider factors such as the weather.

It's expected to be extremely hot and humid locally in the Greater Toronto Area for the next few days.

If you are able, consider going out when the weather is less extreme, or consider bringing a paper bag along with you for safe storage of your mask when it is not in use.

Links to information on this and other practical measures are below.

Have a safe weekend everybody!

Terms to Know Regarding the Wet'suwet'en Stand Against the Coastal GasLink Rout

There has been lots of news coverage on the Wet'suwet'en peoples' stand against the Coastal GasLink pipeline, and lots of information to get through. As is often the case I didn't understand what was going on just from the first article I saw about it (or second, or third...), but a member of a Facebook group with family in the middle of it all kindly shared lots of resources to help me out.

While I was going through articles, I came across a lot of different terms and names, and decided to scrap a summary of the news itself in favour of a vocab and people list instead:

TC Energy (formerly TransCanada) - The company making the pipeline.

LNG Canada - the people who selected TC Energy to fulfill the Coastal GasLink natural gas pipeline.

Royal Dutch Shell plc - the people who own LNG Canada

Wet’suwet’en Nation - the 22,000 square km of unceded traditional territory held by the Wet'suwet'en since pre-colonial times.

The Wet’suwet’en First Nation - the 700-member reserve band village (thanks Merv Ritchie who commented on the referenced thetyee.ca article)

Unist'ot'en - One of five Wet’suwet’en clans. Years ago they established a gated camp along the planned pipeline rout.

"The 22,000 square km of Wet’suwet’en Territory is divided into 5 clans and 13 house groups. Each clan within the Wet’suwet’en Nation has full jurisdiction under their law to control access to their territory" - http://unistoten.camp/about/governance-structure/.

Elected chiefs - Elected chiefs also serve the community in an authoritative role, however their powers only extend as set out in the Indian Act (1876) by colonial federal government, including jurisdiction over reserves.

Band councils - Like elected chiefs, the role of elected band council was created under the Indian Act (enacted in 1876) by colonial federal government.

Hereditary chiefs (sometimes called house chiefs) -  the responsibility of hereditary chief is a position held according to traditional Wet'suwet'en governance. The jurisdiction of hereditary chiefs vary between groups, however hereditary chiefs are the Title Holders of the Wet'suwet'en land. (For more details: affirmation in 1997 by the Supreme Court of Canada, in the decision of Delgamuukw v. British Columbia).

unceded land - land where powers over it has not been legally handed over to colonial government.

Reconciliation - “. . . Reconciliation is about establishing and maintaining a mutually respectful relationship between Aboriginal and non-Aboriginal peoples in this country. In order for that to happen, there has to be awareness of the past, an acknowledgement of the harm that has been inflicted, atonement for the causes, and action to change behaviour.” - The Truth and Reconciliation Committee (https://www.ictinc.ca/blog/what-reconciliation-is-and-what-it-is-not)

United Nations Rights of Indigenous Peoples (UNDRIP) - passed into British Columbia provincial law in November 2019. "UNDRIP clarifies the rights of Indigenous Peoples to Free, Prior, and Informed Consent regarding projects that impact their lands and livelihoods. It also clarifies that Indigenous Peoples will not be forcefully removed from their lands." - https://canadians.org/analysis/five-things-you-should-know-about-wetsuwetens-fight-their-rights

     While there was a lot of "what's happenings" to read about, it took a while to sift through to understand why or just how this conflict came about.
      A key point that I did not initially understand is that consultation with 20 First Nations did actually take place, and representatives from all 20 signed in agreement with the rout. However, the actual title holders to the Wet'suwet'en land did not sign. All five hereditary Wet'suwet'en chiefs -the title holders of part of the land that they are planning to put the pipeline on- are unanimously opposed.

What's a Watershed?

King City, Ontario
Depending on where you live, "watershed" may be a term you hear often. However, many people do not know what a watershed is, or how it is relevant to them.

Not long ago I had the opportunity to learn all about watersheds, but from the start found myself asking what constitutes as a watershed.

What is a watershed?

"the area of land that catches precipitation and drains into a larger body of water such as a marsh, stream, river, or lake" (SEAWA, 2014).

"A watershed is a topographically bounded area... that possesses a measurable drainage area (eg. 100 hectares), where all runoff from a precipitation event will be conveyed downstream, ultimately reaching the outlet of the area" (Introduction to Watersheds, 2020).

Imagine you are sculpting a shallow bowl with gently sloped sides. Now, if you were to add little peaks and indents on the inside of the bowl, you have just modified the topography of your bowl. After the bowl is finished, if you were to leave it out in the rain any rain that fell along the sloped edges would be funneled through the indents down to the lowest point in the bowl, maybe leaving other little pockets of water here and there.

topography: the physical appearance of the natural features of an area of land, especially the shape of its surface. - Cambridge Dictionary

In this analogy, not only middle pool of water but the entire inner surface of bowl is the the "watershed". It is an entire area of land that collects precipitation such as rain and drains it to a common place.

Watersheds exist in many different shapes, and can drain into many different types of water bodies. They are not limited to inland water bodies either; amoung water bodies such as lakes and large rivers, precipitation may also drain towards an ocean (Missouri Botanical Garden, 2002).

On the current Plight of Koalas

Image source: Majesticanimals.net/Heartbreaking images
of confused koala after discovering its home has been cut down

The article attached to this photo explains that this koala survived and is ok. She had suffered some injuries and was taken to an animal hospital where she is in much better condition.

Also, in correction of a previous post, fortunately the report in November 2019 that koalas are "functionally extinct" was erroneous. Though they do still need our help, to be considered "functionally extinct" a species must fall within the criteria below:

1. The population is so low that they no longer play a significant role in their ecosystem. Eg. There are so few they don't put significant dent in what they prey on

2. "A population that is no longer viable", or there are none left able to produce.

3. "Finally, functionally extinct can refer to a small population that, although still breeding, is suffering from inbreeding that can threaten its future viability".

Although the label of "functionally extinct" was erroneous, it did come from the very real sitaution that they are in trouble.

If you would like to donate to help koalas specifically, Living With Koalas has put together a nice list of charities to help them:
