Weekend Activities

Yesterday, after an excellent morning of watching migrant birds (highlighted by over 500 Northern Flickers), I went down to Ipperwash in search of Olympia Marbles. My friend Isabel was with me, as it would be a new butterfly for the both of us.

Not five minutes after pulling into the MNR parking lot (probably the bumpiest parking lot in Lambton County? Maybe Southwestern Ontario?), we found our target. There ended up being several individuals, which was a treat to see. 

There were a few Common Green Darners flying around as well, my first of the year, and probably my earliest ever. I managed to catch one. So far my 2021 swing to catch ratio is about 4:1, hopefully that improves as I dust off my skills...

A few plants of interest in the dunes. 

Bearberry (Arctotaphylos uva-ursi)

Lyreleaf Rockcress (Arabidopsis lyrata)

Rock Sandwort (Sabulina michauxii)

I also found this lichen. Pretty sure it is Sand-loving Iceland Lichen (Cetraria arenaria).


We went to the dunes and swales afterwards for a quick walk. We found another Olympia Marble, as well as come Cabbage Whites. I was hoping to finally get a Brown Creeper for Lambton, but nope...where are they?? I took photos of a couple plants of interest. I will have to come back for some more dedicated botanizing.

Wintergreen (Gaultheria procumbens)

Parasol Sedge (Carex umbellata)

Afterwards, I parted ways with Isabel and started on my way home. I planned to stop into the Parkhill CA on the way for a bit to look for plants, so that is what I did.

As soon as I got out of the car I heard a Ruffed Grouse drumming, and later heard a second. Nice to know they are here!

I made my way down into the ravine. The plants have really come along since I was there two weeks ago. Several species of native wildflowers were seen.

Yellow Trout-lily (Erythronium americanum)

Large White Trillium (Trillium grandiflorum)

Twinleaf (Jeffersonia diphylla)

Cut-leaved Toothwort (Cardamine concatenata)

Dutchman's Breeches (Dicentra cucullaria)

Sharp-lobed Hepatica (Hepatica acutiloba) was one of the more abundant flowers. What a showstopper, it comes in a variety of colours.





Canadian Wild Ginger (Asarum canadense) was beginning to bloom. The flowers lie on the ground, and this is because it is pollinated by ants.

There were quite a few sedges (Carex spp.) seen, and a few were identifiable to species. One of these was Long-stalked Sedge (Carex pedunculata). The long "stalks" (peduncles) were obvious on the plants which were further along. Another good way to identify this sedge is that the leave apices (tips) come to a sudden point, whereas in other species, the leaf comes to a sharp point more gradually. 

Pretty Sedge (Carex woodii) lives up to its common name. This is a species that I have really overlooked in the past. While I have seen this species once before (I recently realized I misidentified a sedge from a couple years back that was this species), this is the first time I have really appreciated and studied it in the field. This isn't a super abundant species, but can be common in the right habitats. 


Of course, Carey's Sedge (Carex careyana) was a highlight. This is a pretty rare sedge that I saw for the first time a couple weeks ago at this location. It is much further along now.

It could be confused with Plantain-leaved Sedge (Carex plantaginea), which also has wide leaves, and is the same taxonomic section, Carex sect. Careyanae. While the leaves are pretty distinct once you get a feel for them (typically a little less wide, and are noticeably unwrinked), if you can see the culms (the "stem" with the flowers), there is an easy way to tell them apart: the bracts. In Carey's Sedge, the bracts (a specialized leaf) subtending (below) the pistillate spike (female flowers) is green (although sometimes there can be a hint of red at the base) and leafy, and in Plantain-leaved Sedge, this bract is red and basically non-existent—there isn't really a leafy bit. Below is a comparison showing this, Carey's Sedge on the left, and Plantain-leaved Sedge on the right.


I am looking forward to keeping tabs on this population as the plants begin to mature! 

I also finally, after scouring the ravine for over an hour, stumbled across some Harbinger-of-spring (Erigenia bulbosa), my first time seeing this uncommon to rare in Ontario species (I have gone out about four times this spring looking!). Unfortunately, it was past flowering, and there were only like four plants. I was pleased, but admittedly a bit disappointed to have missed it in flower. I must have walked right by these plants when I was here a couple weeks ago. 


I ended up taking the long way back to the car. Pretty uneventful, but I got a nice view of Mud Creek.

Today, I had a tip on where to look for another population of Harbinger-of-spring in the Coldstream CA, so that is where I went. I hoped it would be in flower.

It took a bit of scouring, but finally I spotted some. This is a pretty small species, and is quite easily overlooked. Had I not stopped to look at a Carey's Sedge plant (more on that later), I probably would have missed them!

Luckily for me, there were still lots of flowers present, although the plants were past their peak.



I found some more Pretty Sedge as well. Must be indicative of good habitat.

With all the recent warm weather (it got up to at least 18 degrees today, and around 25 degrees yesterday), plants are way ahead of schedule. The forest floor looked like it was at least late April, maybe even early May. I am certainly not complaining, it was a long winter! 

Wood Anemone (Anemonoides quinquefolia)

Mayapple (Podophyllum peltatum)

Red Trillium (Trillium erectum)

Twinleaf

Dutchman's Breeches

White Trout-lily (Erythronium albidum)

Common Blue Violet (Viola soria)

I left Coldstream quite happy :)


On my way home, I quickly checked on a population of False Rue-anemone (Enemion biternatum), another rare species in Ontario. In more or less full bloom, as expected this year I guess! This is one of my favourite early spring species.

Things might come to a bit of a standstill with this week's weather forecast, but it won't be long now—great things are ahead!

Spring Came Early

 Yesterday I went out in search of Ruffed Grouse and spring plants. My first stop was Parkhill Conservation Area, in northwest Middlesex. This is a well known spot for both of the things I was seeking. Last June, I visited Parkhill CA in search of plants, and flushed a bird in the bushed I was 99% sure was a grouse, but since it would be a county bird, I obviously wanted to be sure. 

I arrived at the CA shortly after 7:30 (I checked out the reservoir first, but there wasn't any waterfowl). It was about 5 degrees out, so not super warm, but pleasant. It wasn't long before the Western Chorus Frogs and Spring Peepers started calling.

As I was walking through the woods, I found a single plant of what I believe is Spreading Sedge (Carex laxiculmis var. laxiculmis). The glaucous leaves make it var. laxiculmis


I continued along the top of the ravine. Plantain-leaved Sedge (C. plantaginea) was common.



The short red bracts are evident here!

Wide Leek (Allium tricoccum var. tricoccum) was another numerous species. I might cover this species in more depth in a future post.


The first of the "Hey, that's early" moments came with this Early Meadow-Rue (Thalictrum dioicum). 


Finally, I managed to hear a Ruffed Grouse drumming. New county bird! I heard it a couple times again later. I could now just focus on the plants :)

The first hepatica (Hepatica acutiloba) plant I looked at was this "four-leaved" oddity. Perhaps it was a good luck omen?


Lots of the normal looking plants as well, including some in flower.



Eventually, I decided to descend down into the ravine and head back. Seems I picked the right spot to go down, because I ended up coming across a big patch of Carey's Sedge (C. careyana)! This was one of my most wanted plants, and I was keeping a sharp eye out for it on this day. It is similar to Plantain-leaved Sedge, but the leaves have a more "unwrinkled" appearance. I didn't end up getting any good pictures of it, but the bract (basically a specialized leaf) is much longer and is green on Carey's Sedge, whereas it is short and red on Plantain-leaved. Carey's Sedge is ranked S2 in Ontario, meaning it is very limited in distribution, but it is known to occur in this area. 




You can sort of see the green bracts here...


An assortment of other spring plants, several of which I don't normally see until mid-April!

Early Blue Cohosh (Caulophyllum giganteum)

Bloodroot (Sanguinaria canadensis)

Trout lily (Erythronium sp.)

Cut-leaved Toothwort (Cardamine concatenata)

Broad-leaf Waterleaf (Hydrophyllum canadense)

Mayapple (Podophyllum peltatum)
probable Twinleaf (Jeffersonia diphylla)


I photographed a couple mosses as well, including Bright Silkmoss (Plagiothecium laetum), a new species for me.

Bright Silkmoss

Dwarf Anomodon Moss (Anomodon minor)

I finished up at Parkhill, and the decided to stop into Coldstream CA on my way home. I had just under an hour to explore it.

There was a large naturalized population of Japanese Pachysandra (Pachysandra terminalis) along the river. This is a non-native species. I am not sure how invasive it is, but it is one to be aware of.



I added another species of toothwort to the day list, Two-leaved Toothwort (Cardamine diphylla).


False Mermaidweed (Floerkea proserpinacoides) was just one of the species found in the floodplains.


As I was on my way out, I spied this sedge, which stopped me dead in my tracks. It looked like Carey's Sedge! I am not sure if it is known to occur in this location, although I do know it is known to be found further down the Sydenham River. Although I am pretty sure it is indeed this species, I'll have to go back to confirm it once it grows a bit more.



What an enjoyable few hours! I even managed to get a few plant lifers. I'm sure I'll be back out there soon...
