In the fullness of time, we plan to describe a reasonable inventory of endemic flora and fauna, native or introduced and pests and diseases. The aim is for at least one update per month, except during busy summers.Unknownnoreply@blogger.comBlogger250125tag:blogger.com,1999:blog-8931236.post-80845865863175966902022-01-27T10:00:00.004-05:002022-01-27T10:00:53.423-05:00Facebook and iNaturalist have taken over. <p> I was wondering why I had abandoned this blog that I have enjoyed writing, even if only for my own record, and realized that since 2016 I've started making much more use of Facebook to post interesting observations in this woodlot. Then before the pandemic, I had been introduced to other citizen-science websites like iNaturalist where I could share postings of flora and fauna and with a like-minded community who would share their observations being their own or provide comments on yours.</p><p>The draw of the alternatives, has completely diminished my interest in returning to this blog, other than to maybe share a story with friend on email that aren't on FB or iNaturalist. </p><p>iNaturalist is international at iNaturalist.org as well there is a Canadian version at iNaturalist.ca. Unfortunately, I find the Canadian version limiting, as it always wants to filter observations to Canada. It is much more appealing to see the distribution of the plants and animals worldwide. </p><p>If you are intrested, my iNaturalist username is Leanhoser, and the observations can be viewed at: </p><p>https://www.inaturalist.org/observations?place_id=any&user_id=leanhoser&verifiable=any</p><p>I am now up to 684 observations in iNaturalist, although admittedly many are repetitive. </p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEgmIQyLYaYkjmibLcTTt0Uo-TUFtTRo4VayhIvESYoIxbv0krTStdKzd0bu2mHGG1JwtbSZwBCRSxeeaWbK5gHZeLn9S29MuKZC1nA0aTbPzT4xosJfrbU_O4JmmDJDgrDSCCWKD0QRtWiSXyBH8L1w1dfaG5g9EYRxJb5_Xv0dPvWBf37mFO8=s1600" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="898" data-original-width="1600" height="352" src="https://blogger.googleusercontent.com/img/a/AVvXsEgmIQyLYaYkjmibLcTTt0Uo-TUFtTRo4VayhIvESYoIxbv0krTStdKzd0bu2mHGG1JwtbSZwBCRSxeeaWbK5gHZeLn9S29MuKZC1nA0aTbPzT4xosJfrbU_O4JmmDJDgrDSCCWKD0QRtWiSXyBH8L1w1dfaG5g9EYRxJb5_Xv0dPvWBf37mFO8=w626-h352" width="626" /></a></div><br /><br /><p></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-8931236.post-65196312102365352892022-01-25T21:24:00.003-05:002022-01-28T02:10:39.012-05:00The Crow, Hawk and Owl<p><span class="d2edcug0 hpfvmrgz qv66sw1b c1et5uql lr9zc1uh a8c37x1j fe6kdd0r mau55g9w c8b282yb keod5gw0 nxhoafnm aigsh9s9 d3f4x2em iv3no6db jq4qci2q a3bd9o3v b1v8xokw oo9gr5id hzawbc8m" dir="auto">A

I wasn't able to identify it from my two trusty bug books, Bugs of Ontario and Insects of the Peterson Field Guides Series. Looks a lot like a lightning bug but much wider.

For examples weavers speak of warp and weft, meaning the longitudinal threads and lateral threads when weaving a cloth. Today I learnt three interesting saw-milling terms: cant, flitch and slab. Saw-milling is cutting a log lengthwise to make boards. Once one side of a log is cut it produces the slab which is the waste item and the log then becomes a cant. When a second cut is made parallel to the first it produces a flitch. The flitch is a board that still has bark on the side edges. Once a cant has been cut on all four sides it is still a cant as long as it is used as a source to make more boards. Otherwise it is a beam or board. For making plywood the cant is cylindrical. Plywood is made from thin layers of wood called veneer glued together. The veneer is made by a long longitudinal knife that cuts a thin slice of wood from the spinning cylindrical cant, like unwinding a role.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-8931236.post-49922909655871161132014-09-02T17:29:00.002-04:002014-09-02T17:29:26.010-04:00A Fly Devouring a Mosquito<div class="separator" style="clear: both; text-align: center;">

In this photo a fly pounced on and grabbed a mosquito that I swatted but didn' kill. This is my kind of fly. No idea what type of fly it is. Identifying that will be a project for a winter day.<br /><br />Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-8931236.post-38961674675171974632014-06-15T09:07:00.000-04:002014-08-26T08:07:05.744-04:00The Verdict - Buckthorn Disease is Oat Crown RustI received a number of responses and all led me to Oat Crown Rust as the disease that has affected our buckthorn bushes. Some bushes are so badly hit now that they appear to be dying, or at least severely weakened.<br />
<br />
Thanks to Drs. Andre, Bernard and Richard.<br />

</span> with the Ontario Ministry of Natural Resources provided the following response.<br />
<br />
<span style="font-family: Arial,Helvetica,sans-serif;"> I am pretty sure what you are seeing is Oat Crown Rust, and buckthorn
is the alternate host for this disease. This is a tentative
identification for now and I will send you positive ID once our lab can
confirm this.<br />
<br />
The causal agent of this disease is Puccinia coronata, a serious disease
on oats and as you have seen, can be very damaging to buckthorn too. I
have include a few websites here for your information.<br />

These are the Common buckthorn<i> [Rhamnus cathartica]</i> and the Glossy buckthorn <i>[Frangula alnus]</i>. Both have also been referred to as European buckthorn in different sources, so I have decided to avoid that name altogether. <br />
<br />
In the last week I have found a disease on both species of buckthorn that in some cases has completely defoliated the bush. The disease is quite widespread but still only infecting selective trees. It looks like a bright orange mould as pictured here.<br />

It was about a head taller than our neighbour's full grown St. Bernard dogs.

In the past we have experienced what likely is a carpenter ant. We have been diligently trying to get rid of it with varied levels of success. </span></span><br />
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;"><br /></span></span>
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">This year however we have found a very different ant. It had a black abdomen, a red torso and a larger black head. It has very aggressive mandibles. Based on some very basic research it most closely resembles <i>Myrmica
incompleta (lets call it MI).</i> This species can be viewed at: http://www.insectsofalberta.com/myrmica-incompleta.htm</span></span><br />
<br />
<span style="font-size: small;"><span style="font-family: Arial,Helvetica,sans-serif;">Last summer, I had observed ant wars between the carpenter ant and the Myrmica incompleta so the two species are evidently not compatible. Could it be that MI is now keeping the Carpenter ant away, a blessing in disguise.</span></span><br />

This insect preys on eggs of a horntail -- another wasp that lays eggs in the wood of trees. It apparently 'sounds' the wood looking for horntail eggs to lay its eggs in. This is likely the [Megarhyssa macrurus] as shown on Wikipedia.

In my 60 years I have never seen a cicada until today. While climbing the TV tower to do some work, I found this green Cicada on the roof next to the stabilizing bar of the tower. And there was also quite a buzz in the trees above.<br />

This woodlot is entirely forested but for a few open clearings. Clearings can always be found about the dead butternut stands, which one can assume were created by the juglone toxin produced by the butternut trees when still living. I am looking for sites to plant the red oaks that have germinated. Red oaks are partially shade tolerant so clearings are ideal for planting. The question then is if the oaks are tolerant to the juglone toxin which apparently they are. According to http://pubs.cas.psu.edu/FreePubs/pdfs/xj0039.pdf the following list of trees are resistant to juglone toxin. So far 60 acorns have germinated and to date I have planted 52 in various clearings. <br />

By now all the weevil worms would have emerged and some were still found in the bottom of the fridge. They chewed their way through the plastic bags. The surviving acorns were again float tested and only 130 finally survived. These were then placed on a layer of earth and covered by wet newspapers. in about a week the acorns started to produce a tap root as pictured here. <br />

The bad acorns float and the good acorns sink. In fact after floating them I found that the majority of the remaining acorns very unfortunately floated and failed the float/sink test. So how effective is this test anyway? I decided to dissect a number of good and bad acorns to see really how effective this test is. Results are shown in the following photos.<br />

The sinkers were evidently in generally very good condition. However a number of the sinkers still had larvae exit holes so this test is not 100%.<br />
<br />
At some point the larvae should stop emerging so at that point we should be able to determine that all remaining acorns are clean. I can't store the nuts in a plastic bag if there are any larvae remaining.<br />
<br />
The number of remaining acorns was sufficiently low to count them and 370 acorns are left. That is a loss of 71% of the nuts or a survival rate of 29% and I don't think it is over yet and more losses are expected.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-8931236.post-46662882955568027162012-10-16T11:55:00.001-04:002012-10-16T11:55:53.018-04:00Acorn UpdateRed oak acorns need to be stored in a cool place for a month or so before planting. so I stored the acorns in a plastic bag in the beer fridge cooler.<br />

Much to my dismay, I found many larvae at the bottom of the fridge which tweaked my curiousity. It turns out that even though the acorns were selected many were still contaminated by eggs and the emerging larvae of the Acorn Weevil<i> [Curculio glandium.] </i>Apparently the larvae fall to the bottom of the bag and then chew their way through the plastic thus ending up at the bottom of the fridge. In nature they fall to the ground and then bury into the earth. I found that many of the acorns had the typical exit holes. So I will have to sort the good from the bad acorns one more time. <i> </i><div>

Bert, a colleague in the Ontario Woodlot Association offered me a large quantity of red oak acorns. While there are many Burr Oaks, I have no red oaks on this property and welcome the idea of adding some more diversity on the woodlot. I have very large areas of concentrated ash trees and fearfully anticipate that the emerald ash borer will devastate those areas so diversity should pay off. Bert advised me that the acorns had already been floated and the floaters have been removed so the thought was that what remains are pretty well in good condition. To get an estimate of the number of acorns, I weighed 100 acorns and then weighed the whole box and by extrapolation calculated an estimate of 1270 acorns after taking out the weight of the box.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-8931236.post-85702029277665477802012-07-29T15:51:00.002-04:002012-10-16T09:53:29.491-04:00Tent Catepillars in our Burr Oak by the House <div class="separator" style="clear: both; text-align: center;">

It also has a very lovely display of fall colour. For that reason I was happy to see one red maple sapling west of the house and it has been attempting for the longest time to grow, but every fall and winter it would get the top nipped off by white-tailed deer (Odocoileus virginianus). This is somewhat frustrating since there are so few red maples around. Cutting the top or leader of this tree doesn't kill it but severely stunts its growth. It then has to start over again to find a new leader. The only good thing is that in the mean time it keeps building up its root system in anticipation for a chance to shoot out. Once the tree is about 6 feet tall the leader is harder to reach and it should be safe from deer browsing.<br /><br />To add to the diversity of this woodlot, in May I bought and planted several dozen young red maples from the Ferguson Forest Centre Nursery in Kemptville, Ontario. Thinking that the deer would have ample supply and variety of greenery for food at this time of year, I didn't bother taking any preventive measures yet to protect these saplings from the deer. Alas on my recent inspection of the new arrivals I was much dismayed to find that at least half of the new saplings have already been munched on and topped by deer as seen in this photo. The satchel is placed in the background to provide contrast. <br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjY3B-ouFY5zDOqfJw5W0jFxg1IZtQ-4QtScU8CdyERzlJnXL38_rn0Kmq9DmOacauScJqhwCjKybYBhcj2oAYFxI66nfqEc9qEAecltvdsts0ZzSPBG_YmLBnuwOa_irFK4IzYjw/s1600/DSCN0541.JPG"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjY3B-ouFY5zDOqfJw5W0jFxg1IZtQ-4QtScU8CdyERzlJnXL38_rn0Kmq9DmOacauScJqhwCjKybYBhcj2oAYFxI66nfqEc9qEAecltvdsts0ZzSPBG_YmLBnuwOa_irFK4IzYjw/s400/DSCN0541.JPG" /></a><br /><br />The deer must really favour and be able to sniff out the red maple since many of them were obscured among other greenery. It was quite surprising how they singled out this particular plant. This is discouraging for the success of red maples in the area since all sapling are threatened this way. Instead other much more successful plants and often undesirable invasives like buckthorn just merrily grow and carpet the area untouched by deer. The deer in this case is its own worst enemy in this mix leaving an undesirable landscape for them as well as me. <br /><br />I immediately started to protect the trees, and cut strips of Bounce fabric softener sheets which deer don't like and attache them to the top branch, or leader, of what remains of all the new saplings. <br /><br />For preferred deer foods: <a href="http://www.michigan.gov/dnr/0,4570,7-153-10370_12148-61306--,00.html">http://www.michigan.gov/dnr/0,4570,7-153-10370_12148-61306--,00.html</a><br /><br /><br />Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-8931236.post-68986453526700823772012-04-22T11:48:00.000-04:002012-04-22T11:48:15.139-04:00Balsam FirAs a youth I was always intrigued by the Balsam Fir Tree [<i>Abies balsamea</i>]. The bark of this tree typically produces blisters containing an oily gum. Back in the 60's we often had to entertain ourselves through bouts of boredom as there was very little in the way of electronic gadgets then. So as kids one of the activities we did was break a small twig, poke one end of it into the gum blister and then place the twig in the water of a stream or ditch. The twig would then be propelled by the change in surface tension on the water which was sort of entertaining and even mystifying. This was admittedly only a brief diversion, since we with short attention spans then probably had to run off and pursue imaginary forest spirits, or play hide-and-go-seek or something.<br />
<br />
Our woodlot has a very limited diversity of trees dominated probably by white spruce which was planted in the abandoned fields and white cedar and ash which naturally regenerated everywhere else it seems. To add to the mix I was advised by a colleague woodlot owner that his property is over run by Balsam Fir so I offered to relieve him of some of the seedlings. I since planted 95 Balsam firs from that event.<br />
<br />
This spring I have also ordered and planted Balsam firs, Eastern Hemlocks and Red Maples bought from the Ferguson Forest Centre. All three species are virtually nonexistent here. <br />
<br />
There is an excellent website that gives pretty detailed information on tree species of Norther Ontario which is: http://www.rook.org/earl/bwca/nature/trees/abiesbal.html<br />
<br />
Some of these northern species are also common here and I cut and pasted a portion of the data on Balsam firs below.<br />
<ul>
<li><b>Soils</b> mostly acid, though tolerating a wide range of soil acidity, on textures from heavy clay to rocky soils, underlain by a variety of materials, including gneiss, schist, slate, sandstone, and limestone. Most common on cool, medium to wet sites with soil pH of 5.1-6.0.</li>
<li><b>Late successional</b> or climax species. Replaced after fire by pioneering hardwoods and conifers, such as Aspen (<i><a href="http://www.rook.org/earl/bwca/nature/trees/populustrem.html">Populus tremuloides</a></i>), Paper Birch (<i><a href="http://www.rook.org/earl/bwca/nature/trees/betulapap.html">Betula papyrifera</a></i>), Balsam Poplar (<i><a href="http://www.rook.org/earl/bwca/nature/trees/populusbal.html">Populus balsamifera</a></i>), Jack Pine (<i><a href="http://www.rook.org/earl/bwca/nature/trees/pinusbank.html">Pinus banksiana</a></i>), and Black Spruce (<i><a href="http://www.rook.org/earl/bwca/nature/trees/piceamar.html">Picea mariana</a></i>), it is generally absent for the first few postfire decades.</li>
<li><b>Shade tolerant</b> with less demanding seedbed requirements than many associates, it readily establishes under a canopy of hardwoods and conifers. Usually common in understory beneath pines, aspen, and paper birch. In the continued absence of fire, may assume dominance as the canopy of the pioneering trees begins to die off.</li>
<li>Subject to windthrow, especially on shallow wet soils.</li>

While attempting to find suitable
locations for tree planting, I thought I would plant some
shade-tolerate trees like hemlock and balsam fir in areas that are
completely overtaken by Glossy buckthorn <i>[Rhamnus Frangula]</i> with the hopes that the trees would
in time shade out and out compete the buckthorn. Much to my surprise and delight I already found Eastern white cedars [<span style="font-family: arial,Helvetica; font-size: medium;"><i>Thuja occidentalis</i></span>] growing among the buckthorn as seen in this photo. This cedar is also known to be shade tolerant and appears to be doing well even in the heavy shade of the buckthorn. This is so encouraging. The losing battle with buckthorn can be exasperating at times. </div>Unknownnoreply@blogger.com2
