More on a couple of endangered species, plus a new species for Rondeau, etc.

 Earlier this month, I went to Rondeau to try and get some impressive shots of the super moon. I spent a bit of time ahead of the moon rise, exploring other areas, including the Marsh Trail. One of the first things I was able to get photos of was this Merlin keeping an eye on me.

On the trail itself, I encountered a Short-tailed Shrew. It was dead, and that is the most likely way to encounter one. 


A few more living things were noted, and photographed, including Blue Jays, which are migrating through in large numbers....

As the evening progressed, I went out to the east side of the park in anticipation of a large, orange super moon at the horizon. There was a bit of haze at the horizon, so I waited and got this one as it rose a bit.

I went back a couple of days later, with a different camera\lens combination, as the horizon appeared to be clearer. Unfortunately it was quite windy, and I couldn't hold the camera still enough in such dark conditions especially with such a slow shutter speed, and when there is often more atmospheric interference right at the horizon. So the quality of photo I was hoping for wasn't what I got. 
 
Later in the evening, I got this:

It is sharper, of course, but it doesn't look a lot different than a normal full moon. Oh well, I guess I will have to work on my moon rise photography technique and keep trying!

In other park explorations, I managed to see these things:

Yellow-bellied Sapsuckers are more plentiful, as they are in migration mode. The occasional one may stay the winter at Rondeau.

As the human crowds thin out a bit, deer are more likely to be out and about.

Wild Turkey
Next is a fruiting capsule of the endangered Nodding Pogonia. It wasn't a great year for this species, as the dryness at a critical time of the summer likely had an impact, as did other factors. For those that did flower and produce a seed capsule, this is what one will find. It is a very small plant to begin with, as one can tell in comparing it to the fallen leaves beside it, and so even extra care had to be made as I searched for evidence of seed production. As the capsule develops, it sits upright, and starts to split along some of the lines, enabling the tiny seeds to disperse with a bit of breeze.

Something I was surprised to encounter was this next little critter. It doesn't have a common name, but is a member of the Tree Hopper family, and its scientific name is Stictocephala basalis. According to iNaturalist, it is the first record for Rondeau and although generally widespread across southern Ontario, is not common at all. When I came across this little rascal, I only had my 100-500mm lens, so had to be creative in getting even a few record shots. Fortunately the lens will focus down to 1 metre at 500mm, so that helped.
Next is a member of the Trametes fungal group, commonly known as the Turkey-tail group.
In spite of the fairly sunny and warm temperatures, butterflies have really dropped off, most likely to that stretch of cold overnight temperatures not long ago.

Next is a photo of a fungus called Destructive Pholiota. The first photo shows it a week later than the following photo, indicating that these fruiting bodies don't last very long.

Lots of Common Grackles are migrating these days!

Salamanders are fairly common across the damper areas of the park, but are seldom seen, especially considering how dry the sloughs are now. This one is likely a Blue-spotted Salamander, but with the genetic research taking place by researchers amongst the salamander group, it might be a hybrid.

Mid to late October is one of my favourite times to search for another endangered species, Red Mulberry. This species occurs in very few places in extreme southern Ontario, being limited primarily to Pelee Island, Point Pelee and in the extreme eastern Niagara Peninsula. Rondeau has a fairly good population, but that may be changing as the forest conditions have changed a little more dramatically in the last few years. I intend to discuss that topic in more detail in a future post. In the meantime, in the last week or so, I have been looking for this species to determine its continued presence at known locations, as well as keeping an eye open for new locations. As a result, I believe I have found at least two, possibly three, new locations. The leaves are much fresher looking this late in the season compared to most other trees. The leaves are quite large, round and have obvious 'drip tips'. These drip tips are helpful in that due to the slight hairiness of the leaves, which can hold moisture, the drip tips allow for a greater falling off of the moisture droplets. The leaves have a fairly symmetrical base, unlike those leaves of somewhat similar looking Basswood leaves.

As mentioned, they retain the green colour later in the season than most other species. All of these Red Mulberry photos were taken in the last week. There are numerous non-biting midges present lately throughout the park, and they often take refuge on the underside of the leaf which this next photo shows.
This species never grows as tall as most of the other species it associates with, so if you see a relatively short tree with a trunk only a few centimetres in diameter, and with lots of large green leaves as described above, it may be a Red Mulberry. A species it can be confused with includes Basswood, a native species, and Northern Catalpa which is often planted in built up areas but can be distributed into forests, so be aware!

Death of a Giant Senior Citizen

It is true....one of the giants of Chatham-Kent, indeed of all Ontario, has come crashing down and is now dead.

I'm talking about a tree, an American Beech tree to be precise. The last time I measured it, it was about 95 cm in diameter at the official measuring height of 4.5 feet above the ground. Here it is as of April 2016.
It is located in one of the newest provincial parks in Ontario, Clear Creek Forest Provincial Nature Reserve, at Clearville in southeastern Chatham-Kent. It is one of the least known and visited natural areas of Chatham-Kent. I devoted a blog post about it in my series of Natural Areas of Chatham-Kent a little less than a year ago. You can read that post at this link.

As I was winding down my career with OMNR in 2011, I took some of the colleagues out to a few sites to pass along various aspects of their significance and management. Here is one of my colleagues being impressed by this huge tree......
.....and here is what it looked like this past week. The staff of Rondeau Provincial Park are in charge of administering Clear Creek Forest, and maintenance staff had been here recently to clear the trail from the huge trunk that had fallen across it.
You can see from the first two photos above that there was a lean to the tree, which is typical of many older growth trees as they age. The right hand side of the base of the tree had deteriorated with age, so it was only a matter of time. One of the fierce westerly winds we had over the past couple of months was the deciding moment, and down it came. Although I doubt that anyone was there at the time to verify it, I am quite sure it made quite a bit of sound when it fell! It took another medium-sized beech tree down with it.
 As mentioned, its diameter was almost a metre. According to one source on trees of the Carolinian Zone, where this species is abundant and grows the best, the largest one known a few years ago was 92 cm in diameter. The tree here was several cm in diameter larger, but the other specimen had not been measured for awhile and if it was still alive, may have surpassed this one. Regardless, the one at Clear Creek Forest is/was one of the largest of its kind in Ontario.

This next photo shows how fragile this tree was in its old age. The outer shell looked fairly sound, but the inside at the bottom was quite hollow, again, not unusual for a tree of this age.
 And speaking of age, I did a count of the rings as best as I could although parts of the cut surface were hard to see due to the chainsaw cuts. You can see from this next photo that some of the rings were quite close together, and others were relatively far apart, reflecting the varying ability to grow over the decades. Certainly a lack of moisture at a critical period of seasonal growth would be one limiting factor.
 Close to the centre, it was impossible to count any rings due to deterioration, as you can see in the next photo. However since American Beech is a tree of a closed canopy type forest, typically the growth is very slow in the first few decades of its life. Unless there is a larger over storey tree that dies or falls down providing a significant amount of sunlight to the forest floor allowing young trees like beech and maple to grow vigorously, the growth rings would be so close together it would be difficult to count them. So with that in mind, I estimated that this tree was at least 250 years old, and could very well have been 300 or more years. Large mature trees are known to live up to 400 years.

Now that this tree is dead, it will no longer be providing beech nuts for critters such as the Eastern Grey Squirrel, Blue Jay, various woodpecker species or Wild Turkey.
However its remains will be quite useful for many other creatures over the next few decades until it completely decomposes. In fact it is well known that a dead tree provides life for far more species than a live tree, so all is not lost. Whether it be beetles or other invertebrates, various species of fungi or other creatures, this fallen log will be of enormous benefit to many forms of wildlife. Salamanders will be one of the larger types of wildlife that will eventually call this rotting trunk home.

While I was checking out Clear Creek Forest, I wandered the trail to see what else there was to see. Obviously this provincial park is about more than just one tree, although the older growth character along the main trail is certainly an important one, and a reminder of what large parts of Chatham-Kent once looked like.

Spring wildflowers are finally appearing. I saw several species, including:
Dutchman's Breeches
Hepatica
Bloodroot
Skunk Cabbage
Silver Maple


Birds were not plentiful on this brief woodland visit, just things like chickadees and robins.

I did spend a bit of time on the north side of the road where a very different character of the provincial park occurs. There were geese and ducks in some of the ponds; swallows and kingfishers were searching for food, and a couple of Yellow-rumped Warblers were busy in their search as well. On occasion one of the swallows would take a break and rest on a branch over the water.

A few Ruby-crowned Kinglets were busily foraging along the shrubby edges of the ponds.



May this forest giant 'Rest in Pieces'
