A trip to Meadowlily to teach kids about biodiversity

On Wednesday I was given the opportunity to teach about 200 grade 3-5 students (ages 8 to 11 or so) about biodiversity and why it's important. The students got to visit four stations (catching butterflies, a walk through the forest to learn about trees, catching snails and other ground-dwelling insects, and planting meadow plant species) and at ours they learned about why plants rock, why native species are important, and why maintaining (if not increasing) biodiversity is important. Since kids LOVE monarch butterflies and snails, we used them to illustrate two important points: if we decrease biodiversity by planting grass everywhere then monarchs won't have their food and shelter plant and so they'll disappear, and if we continue to introduce invasive species then we'll continue to see a decline in our native species that we know and love. The kids loved helping Chen round up the invasive snails (he ended up with the equivalent of a 10-gallon bucket FULL of them...it was ridiculous) for his research, and I was surprised to see how much they loved planting wildflowers with Sandra and I.

Now, I say that I was given the opportunity to do this...which might sound weird to many research-intense academics. As a professor at a university (which I'm not; I'm a graduate student), most are required to dedicate 10% of their overall work duties to outreach in some form. Many do within-department outreach (often involving talking to undergraduate students), a few do inter-departmental outreach, some have a consulting gig on the side which is considered community outreach. But there seems to be an ever-decreasing number who truly love doing "real" community outreach: bringing science outside the ivory tower to the general public, whether that be a class of grade 3 students or a special-interest seniors group at a retirement home. The reasons for this I'm sure are vast, and I don't attempt to pretend I know why this is (decreasing funding, increasing student load and increasing teaching load all contribute, along with personal motivation and other intrinsic factors are my guesses), but I think this is doing a real detriment to science in general. When there's an outcry by scientists on Parliament Hill in Ottawa about slashes to government funding for science research, we hope that the general public is behind us and supports our plight. Science research is invaluable and can lead to so many amazing discoveries, and so it should be supported. But if we're not educating the public about the awesome "stuff" we're doing...why do we expect their support? Sure, a lot of people know about tar sands, where they are, what they are, the kind of impact it has to the Canadian economy and even the environmental impact they have. But what about the population genetics of spicebush swallowtail butterflies? What about the diversity of mosses present in nutrient-poor bogs in northern Ontario? What about the plastid genome size of green algae present in a lake in Chile (which may or may not be the same species as the green alga with the same name present in a lake in Australia...)? If we don't tell people why they should care about these research projects, why should we expect them to support us when our funding has been cut? I feel that science outreach is so, so important. This helps foster the scientists of tomorrow! It helps people understand why what we dedicate our life to is important! Plus...the look on a child's face when they learn something new for the first time about something they were blissfully unaware about previously is one of the most rewarding feelings on this planet.

This outreach activity that I did on Wednesday was originally started as a partnership between the Thames Talbot Land Trust (you can visit their website HERE to learn more about them) and a teacher at the local school board. He started a club for high school students called the Environmental Leadership Program, and Dr. Jane Bowles (you can read all about Jane in one of my previous blog posts HERE) helped him come up with activities that the high school students could do with elementary school students at one of TTLT's stewardship properties in the city. The program occurs every year in June, and each year two new elementary schools are given the opportunity to participate in this program at no cost to them. This was important to Jane...get kids out in nature, and appreciate it for what it is not what we choose to make it. Since Jane's death in July last year I've been doing a lot of outreach activities through the Arboretum/Herbarium, and now through this partnership with the TTLT. If I get to do this for the rest of my life, I will be one happy camper. I can see why Jane loved this so much. Every time I do a botany-themed outreach activity I tell myself at the beginning that if I would have made Jane proud, I've done my job. She was quite the lady.

I would LOVE to post pictures of the kids and how excited they were to plant the meadow seedlings and some "action shots" but...that's actually against the law. So instead, here's a photo-tour of the site and a tiny piece of the surrounding area with some cool stuff I saw while I was at Meadowlily. My supervisor and I have been to the area before looking for mushrooms, but we had never ventured this direction into the actual meadow. It was really neat to go there, and I'm definitely going back sometime to explore some more! And to check up on "our" plants :) So without further delay...pictures! There are a lot of them (sorry to those of you with slow internet connections!) :)


Meadowlily meadow, looking East-ish. Don and Drew planning the hole placement for our meadow plant planting.

The Meadowlily meadow looking West-ish (you can see a passing transport truck on Highbury Ave; from where we were you'd have no idea this was right beside a road with a speed limit of 100 km/hr. Amazing what kind of sound buffer nature can be!)

One of our meadow species we were planting: wild bergamot. It's a really beautiful plant with purple flowers that is great for attracting butterfly and bee species. A great garden plant for full-sun locations!

Sandra preparing the milkweed seedlings for the kids to plant (getting them out of those styrofoam trays was much more difficult than it seems. I swear you need an engineering degree to figure it all out. I ended up just digging my fingers in and pulling them out. I got muddy!). This species of milkweed is sometimes called the "monarch flower" (or another name along those lines) since it is the only food source of the monarch butterfly. It was recently taken off the noxious weed list in Ontario, so if you can find some in nurseries, plant some in your garden! And don't kill the caterpillars eating the plants...they'll grow up to be monarchs one day.

Another meadow species, but this one isn't native (native to Europe; naturalized, not invasive, in Canada). A close relative of the dandelion, this is called the common goat's-beard (Tragopogon dubius).

Two TTLT summer interns, Drew and Jamie, digging some of the grass out of the way to make space for wildflower planting! They were a great help during the day.

A view looking towards the river showing the kind of diversity present at the site. 1) an American basswood tree, 2) Virginia creeper, 3) wild grape, and 4) Dame's Rocket in full bloom. VERY unusual for mid-June; usually those are done flowering here by the end of May. We've had some wacky weather!

The three colours of flower you can find in a population of Dame's Rocket: purple, white, and slightly-more-purple-than-white. A great little plant to do some outdoor genetics experiments on. Illustrating genetic principles using real-world examples. Awesome!

One of the branches of the Thames river running through Meadowlily. The water was remarkably high, and moving quickly. No boaters today, but I'm sure if the weather was nicer (overcast, threatening to rain all day without ever having actually rained) there would have been lots!

A really nice, old Bur oak tree that I was admiring for a while and then thought...wait a minute. Are those BUCKETS up in the tree?! That's nearly three stories off the ground. How the heck did they get up there?!

Canada anemone, one of our showiest native forest wildflowers. This species flowers in the spring, unlike the fall-flowering Chinese or Japanese anemone that most people plant in their garden as an ornamental species.

A great example of why planting invasive species in your garden when you live near a natural area is a really, really bad idea: yellow flag iris starting to take over the wetland area at the edge of the forest where it meets the river. Eventually it will out-compete all of the native wetland species around it and it will be a solid stand of yellow flag iris. Might look pretty, but it's not nearly as important to the ecosystem as the native species!

The smallest vascular plant in the world, duckweed, floating on the surface of a tiny stream feeding into the river. I was trying out my new rubber boots here by wading down the stream. They work! Feet dry.

Another unfortunate invasive species taking over. This is forget-me-not. If you live near a natural area, don't plant this species, either!

A very cool insect-insect-plant mutualism we saw during the lunch break. These VICIOUS red ants (we taunted them with a stick to see what they would do, and attack they did!) were defending their little aphid colonies that were feeding on cottonwood trees. The aphids suck out the sap in the main vein of the leaf, and any extra they can't consume pools on the leaf surface as a "honeydew". The ants consume the honeydew for nutrients. I'm sure they would also consume the aphids, if they ever stopped doing their jobs!

It wouldn't have been a day in the great outdoors if I didn't at least make an effort to look for mushrooms. And let me tell you...the crop this year in this area is abysmal. We didn't have enough rain in the early spring, and then had too much rain later in the spring, and so now everyone's confused at what season it is and what they're supposed to be doing. This was only one of two trees that had mushrooms on them. That's it! One single species of mushroom on two trees all day! I felt ripped off.

The same species of fungus (Dryad's saddle or Polyporus squamosus) growing on a very dead tree. Some of those mushrooms were 50 cm across!

I call this picture my "mushroom selfie". I think I'm going to start making this a thing...any mushroom worth photographing gets made into a selfie. You should all do it, too! I was using this particular mushroom to talk about the dangers of invasive species (snails eat the spore-bearing surface, or the location where mushrooms make their babies, of fungi and are likely a huge factor contributing to the steady decline of fungal species in North America. Invasive species are bad!!) either accidentally or purposely introduced to an area.

Hi Mr. Toad! Sorry for almost stepping on you...twice. Don't worry, he's fine. Or she...I don't know how to tell the difference between male and female toads. I always interpret frogs as females and toads as males until proven otherwise.

Garden List 2014 Update: June 3

Here's my updated Garden List from my round of plant identifications last week :) Every time I identify a new plant, I'm always amazed at the diversity we have in our back yard. I've been asked by a couple people how I manage to "fit" all of these plants in the back yard, so here's where I need to come clean about a few things. Ahem...

...my name is Jen, and I hate pulling weeds.

We have a very unique garden at home that is unlike every other in the neighbourhood. It's not because the back yard is a wasteland that is completely neglected; it's nearly the complete opposite. I would bet that we (and by "we" I mean my Dad who is the resident gardener) spend more time on our garden than anyone else in the neighbourhood. It takes a lot of work because we have...no lawn. Well, we've got a bit of a lawn in the front yard, but the back yard is 100% gardens (plus a pond). This means we have A LOT of room for weeds. A lot. But you know what? It's pretty awesome. There are some areas that are naturally weed-free (or at least have minimal amounts of weeds) like the whole north east corner of the garden. There are some plants that manage to escape through fences from each of the neighbours, but that area stays remarkably weed-free. Some hostas, an iris patch, some bleeding hearts, a flowering dogwood, a spruce, a couple of cedars, the requisite daylily (in every single corner of the garden, it seems) and a fir tree. Other corners of the garden, the ones that get much more sun, are a little...unruly. That's where I'm finding most of the diversity of plants, so that shouldn't be at all surprising! In the southwest corner of the garden there are so many plants you have to be careful where you step for fear of not crushing one of the many I haven't collected yet. In that area we have some REALLY COOL native plants that are not yet in flower (so I won't spoil the surprise by adding a list here; stay tuned to find out what they are once they start flowering and are collected for my Garden List!), some of the typical ornamental species that are found in many gardens in North America, and...weeds. Some have spilled over from the neighbour's house, others have been carried in from the rain, and yet more just magically find their way into the yard other ways. It's a pollinator's paradise...I've never seen so many bees and other flying insects in my life! Two weekends ago when all of the violets were out in all their glory I had to be careful where I stepped to avoid all of the bumble bees. Oh, and dragonflies. They LOVE that corner of the garden (that's also the corner with the pond, too, but dragonflies love to sun themselves and that's the sunny corner).

Now that that confession is out of the way (whew! I feel better!), on to the garden list! I forgot to include the legend last time of what all of the colours and symbols mean, so here it is this time:
- Plants in bold text are new to this iteration of the Garden List (numbered from the bottom up so new plants will always be at the top)
- Plants in green text are species native to northeastern North America (specifically, southwestern Ontario)
- Plants with an asterisk (*) beside their name are invasive in this area (again, specifically southwestern Ontario)
- Any plants that I've already blogged about have links included

Cheers :)

Bleeding hearts (Lamprocapnos spectabilis) flowers. This is one of my favourite pictures; I took it in a dark corner of the garden and the flash washed everything but the plant out. Because it was getting dark, it looks pitch-black out. 

Moss phlox in the garden (Phlox subulata); there's also another cultivar that's commonly planted that has magenta flowers instead of light purple flowers.

Trying something new! Garden List 2014

Would you look at that, it's already the middle of May. Where has all the time gone?! This is insane. For halfway through May, we've been experiencing some pretty terrible weather here, too. We had that "irrationally warm day in March that makes you think Spring is actually coming", and then 5 more weeks of Winter. Then we had about a week of BEAUTIFUL Summer-like weather, and then it snowed. Now we've been having truly Spring weather (the weather we usually get in April), and thunder storms every day (got our first tornado watch a couple of days ago! First recorded tornado in Southwestern Ontario was on Tuesday. Nothing like the damage in the southern US; only a low category EF1). All of the wildflowers (and bulbs, for that matter) are WAY behind where they usually are by this time. We have tulips in our garden that haven't even flowered yet. Some of our daffodils have just bloomed. It's a really, really weird Spring. I'm not sure I like this...

This year I've been inspired by some of my British twitter friends to start a Garden List. What's a Garden List, you ask? Well, it serves double duty. First, it's a great way to catalogue everything you have in your garden. This could stop at "green things", or you could do it for every living thing (bugs, birds, mammals, plants, lichens, fungi...). It's a great snapshot of all of the living things for one whole year that exist in the small parcel of land that you call home. The second reason why Garden Lists are awesome is that it teaches you how to identify living things. You find a weed in your garden with little white flowers. How do you know what it is? Where do you go to find out? Is there someone you can ask that's an encyclopedia of plant IDs? What about bugs? Which caterpillars will grow up into lovely butterflies that you want in your garden (like monarchs or swallowtails), and which ones are pests (like the spruce budworm)? If you can't identify the species, then you'd never know! So this year, I'm doing a Garden List and you should, too.

I've also decided that while I'm still at Western, I'm going to take my Garden List a step further. I've restricted my list to everything that's a plant or a fungus, and I'm going to make a herbarium collection of each species (with a few exceptions; I'm not going to dig up bulbs). I'm going to press and dry the plants, or dry the mushrooms in paper bags. Once dry, they'll be mounted on herbarium-quality mounting paper, a label will be made, and they'll be accessioned in a database. At the end of this year, I'll have a record on the computer of every single species in the garden, as well as a voucher collection for each one. I'm excited! And what better way to get back into the blogging swing of things than by bragging about my collection?! :)

Every week I'll post an ever-expanding list of the plants and fungi I've identified in the garden. The plants in bold text will be new from the week before, the plants or fungi with names in green will be species native to Southwestern Ontario (don't expect many of these...it is a garden, after all!). An asterisk will denote invasive species, and I'll provide a link to another blog post if it's a plant I've blogged about before. I decided to do it in reverse-order so that the newest species would be at the top of the list every week. No scrolling required! This is exciting! Here we go! :)

Siberian squill (Scilla siberica) flower close-up

The entire squill plant. Too bad it's invasive...it's so pretty! Spreads by seeds and bulbs disturbed in the soil by tilling

Daffodils. There's nothing for size scale here, but they are TINY. From the soil surface to the top of the plant is maybe 15 cm (6 inches)!

Some of our hyacinths in the front yard. We've got bright pink ones in the back yard, too.

Coltsfoot, a highly invasive species that looks similar to a dandelion but the basal rosette of leaves only appears after the flower has spread seed and died.

Blog Update: it's spring! But also, I'm still here!

Happy Spring!! Here where I live it's really, really hard to believe it's actually spring and not still winter (see picture below for the amount of snow we still have), especially since we had a blizzard yesterday afternoon. Not much snow actually stayed on the ground, but still...looking out the window yesterday afternoon made me very, very unhappy. Seems like this winter is never ending! Because it's a new season, I changed my blog colours to be more spring-y and reminiscent of spring flowers. And, of course, can't have a year go by without featuring my favourite colour on my blog background: PINK! :)




As I'm sure you've noticed (and some of you have actually e-mailed me; I do appreciate your concern), I've been a little...absent from my blog in the last month (and I guess the month before that, too...). It's not because I've lost interest or I've run out of pictures (you can NEVER run out of plants to blog about with a plant blog...), it's because I've been very, very busy this semester. I'm TAing as usual, I'm also recording lectures of another course for an online course project by the department, I'm helping map the second-year mandatory course curriculum in Biology for the department, I've been volunteering with ReForest London (more on that later), today I'm giving a talk to the London Garden Club about gardening with native species, I have a talk tomorrow at a teaching conference about my blog and the impact I think it's had since April 2012, I'm giving a talk in April at the Earth Day Colloquium on campus about the importance of trees in London, Ontario (and the history of trees in London), AND, last but certainly not least, I'm trying to finish my thesis. Whew! I've been busy. I do have more blog posts planned for when the term starts to slow down (April! Less to do in April! Trust me!)

So about this volunteering thing with ReForest London. A bit about the organization first....

ReForest London is a not-for-profit organization that is all about bringing nature back to the city. Their goal by 2020 is to plant one million trees in the city, on public or private property (visit their Million Tree Challenge website HERE). There are many different ways to volunteer with the organization (tree planting, they have a neighbourhood Tree Captain program, tree giveaways, tree sales, etc.) and I've chosen one of their new programs to volunteer with called the Tree Teacher Program. There are three presentations that we give: Native Trees, The Importance of Trees, and The Emerald Ash Borer. The goal is to start educating the public about why trees are important and valuable, how they improve the quality of life of people living in the city, and why our natural areas should be protected. I've been having a great time with the program so far, and the most rewarding experience by far were my three talks with the Boys and Girls Club in the Teen Zone. The Teen Zone is where (obviously) teens come together after school to use the computers, play video games, do arts and crafts, sit on the couches and talk, or use any number of the facilities they have in the building. The ages of the teens participating in the program is probably 12-15 (just a guess based on conversations I've overheard about school), and they're interested in being on the computer or playing computer games (or listening to music really loudly) in the evenings and nothing else. To try to teach them about why trees are awesome was a big challenge, but I'm always up for a challenge. Oh, and of course I couldn't use the words "learn" or "teach", because that sounds WAY too much like school and that brings their interest level from 10% to -400%. So instead we "talked" about trees. Much less threatening.

The first session we talked about native trees and why trees from this area were pretty cool and worth knowing about (NOT learning about! Ha). I had them draw pictures about why trees are important in their life, and we played Tree Leaf Bingo. They had a blast, and learned a bunch. They were probably shocked that I managed to squeeze in some learning during non-learning time! The next time I talked about why trees were important (using their pictures in my presentation, which all of them thought was pretty awesome), and then we learned how to identify trees using a simple binary key and herbarium specimens (since trees with leaves are clearly hard to come by at this time of year...). They were SO IMPRESSED by herbarium specimens that now they want to come to campus to visit the herbarium and check out the stacks. Who would have thought that a herbarium would be a "cool place to visit" in the eyes of a 14-year-old that hates libraries?! One of them even told me at the end of that session "herbarium specimens are cooler than candy." If you say so! :) The third session was about Pests and Pathogens of Trees (a modification of the Emerald Ash Borer presentation), and that was the one that went over the best. I was allocated 30 minutes for a 15-minute presentation, some questions, and an activity. The session ended up going for 2 hours. TWO HOURS! It was two of the most rewarding hours of my life. All of the teens want to come to campus to visit again to walk around and visit the trees in the arboretum: the oldest, the biggest, the funniest-looking, etc. I never in a million years dreamed that I would turn a bunch of kids from "trees are boring" into "I WANT TO COME VISIT TO LEARN MORE ABOUT TREES!!!" It was amazing. Just goes to show that a little perseverance and a lot of patience can do wonders.

So. That's my life in a nutshell over the last couple of months. As much as I love what I'm doing, I can't WAIT for life to slow down a bit! I've been counting down the days until the end of classes, which is really unusual for me because I love interacting with students so much. But the end of classes means the end of marking essays. And as much fun as that is...I'd rather not :)

More blog posts (especially about plants) coming soon!

The most hated plant in North America

Today is a very special blog post, brought to you by one of my very best(est) friends, Tanya! Everyone say Hi to Tanya! (Hi Tanya!) Tanya gets to work outside all day every day (OK, not all day every day, but she gets to be outside A LOT with her job), and has some really awesome pictures of really unusual plants in North America. This one certainly isn't uncommon, but that doesn't make it any less special! This blog is her first (of hopefully many!) guest post for my blog, and she's writing about a plant most of us absolutely hate. And if you don't know if you hate it...do you get a runny nose and red, itchy eyes in the fall? Yes? Then you hate this plant. Trust me :)

Without further ramblings by yours truly, take it away Tanya!

There may be another plant that a greater number of people despise (dandelions, maybe?), but for sheer intensity of feeling, I would argue that the most hated plant around must be Common Ragweed (Ambrosia artemisiifolia).  Every year in mid-August, many of us get that old, familiar itchy-eyes and runny-nose feeling that sends us running for filtered, air-conditioned air and antihistamines, and Common Ragweed is most likely the culprit.   

As Jen mentions in THIS POST, many people blame their fall allergies on showy flowering plants like the innocent goldenrods.  But, in order to cause your allergic reaction, you must breathe in the pollen grains, which means that the plant you’re allergic to is wind-pollinated: the plant produces lots and lots of pollen light enough to be blown around in the wind, and it’s betting that some of it will land on the female parts of another plant of the same species.  Plants that use this strategy have small, inconspicuous flowers because they don’t need to expend energy to attract pollinators like bees and butterflies to carry the pollen around for them.  Common Ragweed falls into this category: its pollen can be carried by the wind for hundreds of kilometers.  It’s hard to get away from this stuff.

Common Ragweed is native to North America (Jen says: I put "non-native" for the species status so that I could have a diagram with the "Invasive" box highlighted!) but has become an invasive species in Europe and Japan.  It is a “supertramp” species (yes, that’s a legitimate ecological term), which means that it produces lots of seed, disperses widely, and does really well in disturbed habitats. When you start looking for Common Ragweed, you’ll most likely find it in highly disturbed areas, like beside roads and in agricultural fields rather than stable forested areas, so really, it’s all our fault there’s so much of this stuff around: we’ve created lots of habitat for it!  There’s probably much more Common Ragweed around now than there was when Europeans arrived in North America.  You can burn it, pull it, mow it, or kill it with chemicals, but it will most likely come back in full force the very next year.  A good argument for increasing the amount of healthy forest and grassland habitats where Common Ragweed can’t compete, I say.

Ragweed leaves are compound and finely divided, and look a little like Wild Carrot (Daucus carota, which you can read all about in THIS POST) or Yarrow (Achillea millefolium, which you can read all about in THIS POST).  The flowers and seeds are produced in a tall spike called a raceme, and the plant grows to be about one meter in height.  This means that, in many areas, it isn’t completely covered by snow throughout the winter, and any of the seeds remaining on the plant remain accessible to animals like birds and small mammals.  The seeds have a very high oil content too, which makes them even more valuable to wildlife.  When Common Ragweed is causing you or your loved ones autumn misery, think about the mice and voles that will be depending on their stored ragweed seeds to survive until spring... and in the process, spreading them all over the place so there will be lots more for next year!
