Visit to the Carolinian Forest and the Comfort Maple.

Last weekend my wife Carroll and I were in St. Catharines, Ontario and surroundings to attend an OWA (Ontario Woodlot Association) meeting and to tour some local woodlots. Even though it rained steadily all day Saturday and most of Sunday it was a great visit.

The area on the Niagara Peninsula is now covered with vineyards, were the area used to be dominated by fruit trees. On Sunday we visited about half a dozen woodlots. I understand that the area forests are called Carolinian since the forests resemble those of the Carolinas in the United States. We saw many tulip trees of formidable size, black walnut is very common and well established. We also saw sassafras trees, which is quite rare here but common in the mid-eastern United States. Because of the climate there is a much larger diversity of plants and trees and the trees grow much faster.

We visited several woodlots that belonged to OWA members including a mature maple sugar woodlot, a newly planted field, soon to be forest, and several other forests with spectacular and unusual trees like the chinquapin oak and a swamp white oak.

The day culminated with a visit to the spectacular “Comfort Maple” pictured above. Carroll and I are to the far right and right next to the dog. The others are the hard core OWA members that stayed on after the meeting regardless of the rain. This tree is claimed to be the oldest living sugar maple in Canada. It is estimated to have germinated circa 1500 a.d. http://www.geocities.com/Heartland/Hollow/3442/comfort_maple/photos/photo_2.html has pictures of the tree and a short description.

In an attempt to measure the tree, I used the reach of my outstretched arms which is very close to two metres and it took about three and half of these to measure the circumference. So the approximate circumference was thus seven metres. The diameter is calculated as 2.22 metres (7 1/3 feet). On any account, this is a big tree.

Field Session on management for value of red pine plantations in the Petawawa Research Forest

Today, I and 14 other members of the Renfrew Chapter of the OWA attended a field session on management for value in red pine plantations in the Petawawa Research Forest. Steve D’Eon, Forest Manager of the Petawawa Research Forest (PRF) hosted the session.
A little background to the Petawawa Research Forest – it was established as a forest research site in 1918 and is the oldest continuously operated forest research centre in Canada. The site encompasses 100 square km; about 85% being productive forest land. It is dominated by mixed wood stands (70%) and also containing stands of hardwood (22%) and softwood (8%). Until 1996 the site hosted the Petawawa National Forestry Institute and more than 2 000 experimental plots and sites were established. In 1996 the research programs were transferred to other Canadian Forest Service research centres across Canada but the PRF remains, has been maintained and serves as a facility for scientific research by the CFS (Canadian Forestry Service) science and technology networks and for co-operating scientists and partners from other agencies.
The program for the session involved plantation red pine (PPr) with three general aspects being examined:
1. Initial spacing: how red pine uses the site and responds to density such as those created by planting at different initial spacing. We visited Crowbar's Field – Crowbar was the name of the farmer who owned the field before it became part of the Forest – within the PRF which has 7'x7', 10'x10', and 12'x12' initial spacing. This site provided excellent teaching tools to illustrate the biology of growing PPr and was very interesting to observe the reaction of the trees under these somewhat clinical conditions.
2. Thinning: how one can manipulate density later in a plantation's life to grow more valuable products. We looked at a first thinning (age ~30+) at the PRF Sturgeon Lakes area and then some older plantations that have been thinned a few times to different residual densities. We also looked at some data from a rich site, data on products and prices for those products and relate our yields/values to the thinning regimes and the site productivity. The Sturgeon Lakes area is on the poorer side of sites.
3. Next crop: Growing the next crop using plantation red pine as a starter crop. We looked at three options on what one can do as a plantation approaches rotation age to start the next forest/plantation. These are, clear cut, plant in strips, under plant Pw using two planting layouts, and catch natural red pine with scarification. Scarification basically means to scratch the duff layer on the ground to expose the mineral soil that thus allows tree seeds to take. This was also at the Sturgeon Lakes area where PRF staff are generally practicing continuous cover forestry using plantations established in the 1930's.
It was an excellent day despite the rain showers.

The Butternut Tree

So far I have identified about half a dozen butternut trees on this woodlot. In certain areas all that remains are dead trees likely killed off by the ice storm followed by the Butternut Canker. I will have to check them out more carefully one day to determine the cause of death. Other trees appear completely healthy. One article that reports on a study of the DNA of the Butternut Canker fungus states that the disease had been introduced to North America around the 1960’s. The disease has had a devastating effect on the NA butternut population which centres around Northeastern US. In Canada it exists in Southern Quebec, Southern Ontario and parts of the Maritimes. In some areas of the US, the populations have been reduced by as much as 80%.

Several of the Butternut trees here seem to remain quite healthy and according to internet research i.e. see: http://www.na.fs.fed.us/spfo/pubs/howtos/ht_but/ht_but.htm biologists are interested in finding surviving butternut trees with the hope of finding a canker resistant strain. In Canada The Forest Gene Conservation Association, based in Peterborough ON, wants landowners to come forward with reports of occurrences of the tree. See http://www.fgca.net/conservation/sar/butternut_helpus.aspx

There is another project one could embark upon in one’s spare time.

How we moved one very big rock

The sub-soil (that below the organic layer) of this woodlot is primarily made up of glacial till, or what the locals call “hard pan”. According to the Dictionary, till is “Glacial drift composed of an unconsolidated, heterogeneous mixture of clay, sand, pebbles, cobbles, and boulders” and I would say that pretty well describes our subsoil. It is called hard pan because undisturbed till is very hard to dig. Once disturbed though it can turn into a soup if wet enough. The till deposits or small hills left by the glaciers, around this area are commonly referred to as the “Drumlins of North Gower”. North Gower is the old township name for this area before it was grouped with Marlborough Township to become Rideau Township which in turn was amalgamated with the City of Ottawa.

The till here contains predominantly bluish grey rocks which I am led to believe is limestone. It is the same material that construction gravel is made of in these parts. There is the occasional but rare granite rock amongst them.

There was one rather large such rock that I had to move from our backyard about 20 metres (65 feet) to the fence line. The rock was large enough that I could not budge it even with a well-positioned 2 metre long pinch bar used like a lever. The rock measured roughly 1.2 M (3.93 ft) by 0.4 M (1. 3 1ft) by 0.5 M (1.64 ft) for a total volume of 0.24 cubic metres or approximately 8.4 cubic feet. These measurements are rough to around 10% but probably good enough for this purpose.

The first problem was to get some idea of the weight of the rock. I found a much smaller rock of the same material that was as large as I thought I could reasonably lift. If I knew then how much it weighed I would definitely have found something smaller. In a large olive pail from a restaurant I submersed the rock in water and made a mark on the inside of the pail at the water line. I then withdrew the rock from the water and then determined the volume displacement of the rock by carefully measuring the amount of water it took to refill the pail to the mark. I needed 13 litres plus or minus 100 ml of water – Eureka!

Using the average reading of several weigh scales I found about the house including a bathroom scale and some others, I determined that the rock weighed close to 79 lbs. plus or minus a pound. Yes the weigh scales are still in pounds. This equates to 35.8 kg. Doing the math then, the density of the rock is 2.76 metric tons per cubic metre or 172 lbs. per cubic foot.

To give some idea of how heavy that is, a rock the size of a NBA regulation size basketball would weigh around 20 kg or 44 lbs., the weight of a healthy six year old boy.

With these conversions the rock turned out to weigh around 661 kilograms or 1460 lbs. It is no wonder that it wouldn’t budge with the bar. This is the weight of a small automobile such as the VW Rabbit.

To lift the rock I erected a tripod over the rock and hung a 2 ton (4000 lbs. or 1814 kg.) rated chain hoist from the peak. A chain hoist has a gear mechanism with a built in brake, and two sets of chains and gears. One set is the lifting chain which moves very slowly, while the other set is a looped chain that the operator pulls on. The gearing has a high mechanical advantage so as the operator say pulls three feet of chain on the loop the lifting chain might move an inch or more. The operator has to pull on the chain in either direction to raise or lower the lifting chain.

I made the tripod out of three eastern white cedar polls each 5 metres (16 ft) long. I initially tried 6 metres (20 ft) but the poles would bend under the weight. If the poles were not green and had a chance to dry for six months this likely would not have happened. At the narrow end the 5 metre poles were of a 9 or 10 cm diameter. The next problem was how to securely fasten the three poles such that it would hold such a large weight. While at the Forest fair several weeks ago I observed some boy scouts erecting a tripod and borrowed that method. The scouts lash the poles by laying down the three poles next to each other on the ground with all the points together. They fasten the rope (clove hitch) to one pole and then proceeded to weave the rope over and under each adjacent pole back and forth until they have 12 rows (six each way), a bit like basket weaving. You will probably find this in any Boy Scout book. Actually I have since found an excellent description of this method on the following Boy Scout website: http://www.4thtyldesley.co.uk/skills/lashings/lash003.htm

Once fastened the poles are lifted up. The end poles are spread apart and the centre pole is pushed ahead and voila a sturdy tripod.

I used a 2cm, (¾ in) diameter polypropylene rope for the lashing which worked well and is quite strong.

To fasten the rock to the hook on the hoist, we used a very heavy chain with a grab hook. Placed the chain around each end of the rock and crossing over the chain in the middle and on top of the rock.

At first we needed to move the big rock up an incline for several metres. We did this by lifting the rock with the tripod centred slightly uphill. Lifting the rock would drag it up a bit, we would then lower it, reposition the tripod and repeat. This put a tremendous amount of pressure in the one down hill tripod leg, but it held. It is critical that the tripod straddles the rock. In other words the rock must sit inside the triangle created by the tripod feet. If it doesn’t the already heavy tripod could flip over with a huge and dangerous weight attached to it.

Once the rock was moved to a flat surface, we fashioned a cradle two metres long by 1.2 metres wide out of six boards – three lengthways and three crossways and evenly spaced apart. The boards were cut at the sawmill so were of various thickness’ around 10 cm by 7 cm. (4X3).

We laid down three other three-metre long boards on the ground under the rock, like railroad tracks in the direction that we wanted to move the rock.

We used as rollers the three pieces we cut off the poles we shortened. We placed the cradle on the rollers, which were on the railroad tracks, and then slowly lowered the rock onto it.

Using a chain and the ATV we slowly pulled the cradle with the rock in the desired direction. One of us drove while the other kept feeding the rear log roller to the front under the nose of the cradle. At one point the last roller slipped off from under the cradle. The tail of the cradle was dragging on the ground and the ATV even in bull-low four-way differential lock could not budge it. We were able to move it using the Dodge Ram.

Because the terrain was not always even, sometimes the nose of the cradle would dip down into the ground and we had difficulty getting the next roller under. To resolve that problem we used a car jack (scissor type) to lift the front end of the cradle and placed the roller under.

The rest was pretty easy. Once at the destination, we moved the tripod over the desired spot and lifted the rock off the cradle, removed the cradle, rollers etc. and lowered it into position. The beauty of the tripod method with the chain hoist was that we could very carefully and precisely position the rock with a bit of lateral (sideways) pressure, even for a rock that big.

Planning Meeting for an Ottawa Area Chapter of the Ontario Woodlot Association

Planning Meeting for an Ottawa Area Chapter of the Ontario Woodlot Association

Attended a meeting in Kemptville at the OWA Office to begin planning the establishment of a local Chapter of the OWA. Right now the closest chapter that is accessible to local woodlot owners is Renfrew which is an hour and a half away. The OWA Exec Director as well as another member who is also on the EOMF Staff and I attended. We discussed the requirements for a Chapter, decided on the interim boundaries, prepared a short-term workplan and a possible kick-off event.

Outdoor Woodlot Conference 2005, also Useful Silvicultural Guide.

Attended the event, which this year took place just north of Eganville. Where we had rain last year, this time we had beautiful summer weather. It was an unbeleivable 28 deg. c. (82 deg f.) and sunny with a few clouds. I found the few sessions I attended again quite interesting, although the focus was on sugar maple woodlots of which I have very few. I think I finaly grasped the concept of basal area at one of these sessions. Basal area is a measure of the density of cumulative cross sectional wood in the trees in any one spot. It is readily calculated using a foresters prism. The method is quite approximate and is most effective if the density and size of trees are uniform.
I offered to volunteer to man the booth for the Renfrew Chapter of the Ontario Woodlot Association, so did not partake in all the events, but did take in one session plus one short woodlot visit.

The gem I picked up at this event was on how to manage cedar of which I have quite a lot. There is very little on cedar management in the literature of more conventional texts. One of the attendees who is a forester for the Renfrew County gave some excellent tips as well as refered me to a text entitled “A Silviculture Guide to Managing Southern Ontario Forests” which devotes 30 odd pages to just cedar management.

I have since bought the book through the website at: for a mere $27.50 cnd, or approx. $24.00 usd. It is a wealth of information, rightfully refered to by some as the bible. It is a total of 648 pages plus a 19 page preface, jamb packed with information. Can’t go wrong for the price.

It can be ordered by mail at:

Kemptville Forest Fair 2005

Attended the Forest Fair again this year. The weather was great. The main feature of the fair is the wood auction and this year there seemed to be more wood up for sale than last year. There was a wide variety of wood from cherry to maple, oak, butternut to name a few. There were also booths of local organisations as well as sales booths for books etc. There was one section with a display of insects intended for children. The display was quite interesting, and of course I had to inquire if the display manager knew anything about the glow-worms that I have found here along our driveway. This seems to be an uncommon insect. Since then I have collected four glow-worms in a pickle jar and sent them to her (display manager) to add to her collection of live insects. She will be feeding the glow-worms meal works since the glow-worm is predacious. The mealworms apparently thrive well on breakfast cereal.

I look forward to getting a report of what type of a beetle this worm is related to.

The following is a notice I received about the forest fair which has some helpful information:

To All;

Just a quick note to remind everyone the Forest Fair of Eastern Ontario is this Saturday September 24^th 2005. The fair will be held at the Ferguson Forest Center located in Kemptville. There will several forest related exhibits and workshops, kids events, live music and plenty of food. As always there will be a large Log and Lumber auction. This year will be the best ever - there is an excellent assortment of both softwood and hardwood logs and lumber. This year we have a great quantity of Black Walnut logs – perfect pieces for wood turners, other species include; cherry, hickory, basswood, butternut, white oak and sugar maple. There will be a portable sawmill on site for custom sawing. The fair runs from 10:00am until 3:00pm.

Tree Identification Workshop sponsored by the Friends of Gatineau Park

Attended this workshop which took place at the Gatineau Park Visitor Centre, 33 Scott. Rd. Chelsea Quebec. This park is located north of the City of Ottawa and took a little more than an hours drive to get there from here. Since moving to Kars I have spent very little time in the Gatineaus but while living in Ottawa it was quite popular for our family. There are many excellent and well maintained cross-country ski trails there. The International Gatineau 55 Cross Country Ski Race event used to be held there.

The Tree identification workshop was a full day from 930 to 1630. Like all events it is the few little gems of information that make these events worthwhile. The level of the workshop was a basic introduction or Tree identification 101, but it is good since it gets one organised in understanding the methods of identification. We spent some time understanding the use of Keys for identification. We learnt about terminology for identifying leaves, names for leaf shapes and terms for parts of the leaves. I was particularly interested in easily distinguishing the types of ashes that we have on our woodlot. There are white, black and green ash that are common around here. I learnt that black ash is the only ash that has no stalks on the leaflets. That was a start for me anyway.

A simple trick to help in tree identification is the MAD-VE Rule. MAD-VE stands for Maple, Ash, Dogwood, Viburnum (- not Virbinum, sorry), Elderberry. These are the only trees that have opposite leaves, stems and buds. All other trees are alternate.

Another gem, the leaf of the slippery elm has a sand papery texture, whereas the leaf of the American Elm is smooth.

We also discussed tree silhouettes and much more. It was a good introductory course.

In the afternoon we did a field trip and went through a few tree identification exercises. What struck me was although this area is only about 40 km away from home the selection of trees have changed quite a bit. For example bur oaks which are common in Kars are just not heard of in these parts of Gatineau Park.

The field trip focused on identifying Basswood (American Linden), White Spruce, Slippery Elm, Tamarack (Eastern Larch), American Elm, Trembling Aspen, Paper Birch, and Red Oak.

Myself and two other classmates almost walked into a black bear sow and her cub, which added considerably to an already exciting day. We heard later for the park staff that a sow and cub have been relocated away from the area and that these two where likely the same pair that have returned.

Re: Found a Black Frog

As a follow up on the curious black frog I sought out the opinion of some more informed persons. In my past wanderings, I had come across the Bishops Mills Natural History Centre. So I fielded the question to Frederick W. Schueler of the Centre.

Response from Fred:

there are two possibilities - it's either a very cold Frog (Rana sp.) reacting to cool moist temperatures in an unseasonable way, or it's a melanistic variant of one of these species. The melanic pigmentation of
any animal can be overproduced and result in a black individual. On the other hand, the melanaophore pigment cells of many frogs can expand in certain circumstances - characteristically on dark background or when
it's cool and wet - and produce a black colouration, This is most frequent in Wood Frog males in the spring, and in small toads taken from under cover in black soils in the summer.

Did you retain the frog? And if so is it still black?

To that I replied and the following discourse ensued:

Pieter wrote:

> Your explanation sounds plausible. The frog was found when I stirred up a rotting woodpile. It emerged from under plastic that was covering the pile.

Response

I would think a Wood Frog or Green Frog is most likely. I didn't mention that young Green Frogs have a variant called "melanoid" in which their skin is dark and fairly transparent - this is a graduated thing so an individual can have more or less of it - so if it was a Green Frog it might have been predisposed to blackness by having a bit of melanoid in its makeup.

---------

Fred also directed me to an interesting bulletin board which is the NatureList or Eastern Ontario Natural History list-serve at:
http://mail.thenaturejournal.com/mailman/listinfo/naturelist_thenaturejournal.com

I have subscribed to the site and it is quite intriguing. It does a good job at connecting those who are inquisitive with questions about nature related topics with those who are informed and have the answers.

Glow-worms are Back

This evening several dozen glow-worms were observed along our driveway. This was previously reported September 15th 2004 when the numbers were considerably less than this year. So they are thriving.

Black Frog

Today I found a black frog behind the house. It definitely had the shape and behaviour of a frog and not a toad. Its skin was pitch black and glossy. It is a bit smaller than a full sized leopard frog. Not knowing what species it was I made a mental note and went on about my business.

Following up in the Peterson Field Guide on Reptiles and Amphibians*, I was expecting to find the frog, but much to my surprise no frog nor toad exists in the guide that meets this description. An internet search only identified black frogs in other and usually tropical continents. Had I known that this frog is not so common I would have caught it. But then what could I do with it, besides possibly take a picture.

Is this a freak of nature I wonder? If anybody knows any more about this type frog or has an explanation for it, I would be interested to know. Please leave a comment or email me at leanhoser@canada.com.

Woodlot Site Visit with Eastern Ontario Model Forest Staff

The Certification coordinator for Eastern Ontario Model Forest (EOMF) out of Kemptville spent the morning with me walking the Heartwood woodlot. The EOMF Certification program - see website - is an organisation established to promote and recognise sustainable forestry. One of the EOMF programs is the qualification of identified woodlots that meet a specific standard, thus ensuring that the woodlot is well managed within specific guidelines.

We are seriously considering certification for our woodlot since we strongly support the values espoused by EOMF and definitely support the “Seven Generation test” of sustainability. For more detail on the test see the EOMF website.

The morning was very enlightening, since my guest was very well informed and familiar with the local tree species. We found many butternut [Juglans cinerea L.] trees in the north end of MFTIP Plan Area C , and many of these were damaged and diseased due to the ice storms, while several in Area F were very healthy. Now that I was able to identify them I have found several more near the acre around our house.

We found a dogwood in Area G which stood about 6 feet high like a small shrub, unlike the more familiar and much shorter red osier dogwood [Cornus stolonifera] that is bush common in various spots throughout the woodlot. We were not able to definitively identify this dogwood, and I will have to return to the field to make a certain identification with field guides in hand.

In the same area G we found pin cherry [Prunus pensylvanica L. f.] and black cherry [Prunus serotina Ehrh.].

At the lowland Area F we found a jack-in-the-pulpit [Arisema triphylle] in seed. All that could be seen now was the short 30-cm. stalk with red berries. Upon first inspection I thought it was poison ivy since the leaf shape is very similar to it, but poison ivy has white berries, not red. Also this plant was isolated which is not a common characteristic of poison ivy.

Just as we exited the woodlot we found service berry. I had previously suspected that I found service berry [Amelanchier stolonifera Weig.] here but this was confirmed by my guest. I found this to be difficult to distinguish. I notice that there are a number of different types of service berry, again more detailed inspection will be required to confirm which exact species we saw.

Blue Jays – Even the Bird World has its Rascals

The mischievous blue jays [Cyanocitta cristata] have returned as they do year after year. Mid summer they always leave the local bird population in relative peace and free of gang warfare but alas there is peace no more. The American robins [Turdus migratorius] take particular exception to this gang behaviour on their turf. And in winter the Jays are fighting with the (Northern) Cardinals [Cardinalis cardinalis], they just won’t quit.

Among this gang is one blue jay that has a distorted call. When it tries to call, cajole or cry out, all it can muster is a strange cackle or rattle. That same distinctive bird and its cohorts have returned each year that we have been here.

A very predatory orange cat that we thought at first was feral, but now think belongs to one of our neighbours, and that they appropriately call “Venom” continuously visits us. We keep our two cats “Brutus” – the bully-boy-bruiser – a big neutered orange and white bowling ball, and “Missy” our affectionate and fluffy Birman, (looks like a fluffy Siamese cat) indoors from late fall – when it is too cold – to mid summer.
We don’t let our cats out until mid August, when the bird hatchlings have all fledged and gone into adolescence, and even then we only let the cats out for short day trips.

Venom and Brutus seem to like to hang out together. I fear however that Venom is teaching Brutus some bad bird catching tricks.

Back to the blue jays, they make excellent warning sentinels for the cats. The cats are easily found by following the cacophony of blue jays who will follow the cats while calling the alarm of imminent danger from the tree tops overhead. It helps me find and chase Venom away with my handful of rocks for throwing, which by the way is very inaccurate while on the run.

A Scream in the Grass

In the middle of this afternoon will walking into the tall grass near the house I heard a peculiar little scream being repeated. As I walked closer to the source of this sound I found a garter snake that had caught a leopard frog by the hind legs and started to consume it. The snake was of a medium size while the frog was quite large, so the eating process was quite tedious and slow, the frog of course was under stress and quite alive and thus screaming. It is a very peculiar sound coming from a frog. As I approach the situation the snake would back up into the grass, but it was easy enough to find because of the repeated call from the frog. I decided to let nature take its course and not to interfere.

ATV - Quite the Tool for a Small Operation

Three weeks ago I procured a 1997 Suzuki King Quad ATV. It has 2-wheel, 4-wheel, or 4-wheel differential-lock wheel settings; three gear range settings - high, low and super low; and 5 forward shift speeds and one reverse. So one could say that it has 18 speeds (6 speeds for each range setting). This 300 cc engine equipped ATV is apparently considered one of the best for low speed and high torque work.

The ATV came with a forward winch, a ball hitch and a chain grab hook also fastened to the hitch. About chains, several years ago I happened to have purchased an ols style logging chain at a farm auction, never really thinking that I could use it for anything more elegant that pulling other vehicles out of a rut with my 4X4 ’91 Dodge Power Ram 150. The chain has a grab hook at one end and a slip hook at the other.

A grab hook is shaped with a slot allowing the hook to grab a link in a chain whereas the slip hook allows the chain to slip through like a lasso.

I was quite impressed with what this little machine can do. I was comfortably able to skid very sizeable – up to 30 cm (12 in.) diameter at the butt end and 5 metre (16 ft.) long – logs.

So the logging chain has been used extensively for the last weeks of my summer holidays. Skidding logs can be a very dangerous mind you, if the chain is not properly hitched to the tractor. For example http://www.health.state.ny.us/nysdoh/face/02ny055.htm is a report of a fatality caused by the chain being fastened too high on the tractor hitch and used on steep terrain. In the case of the ATV thankfully the hitch is exactly at the level of the rear axle. When the load is too heavy such as when a skidded log gets stuck behind a stump, in super low and differential lock, the four tires will merely dig four holes. Also the terrain on this woodlot is quite level having been a farm.

To move rocks of up to 500 pounds, I built a 1-M. (3 ft.) by 1.5 M. (4 ft.) stoneboat or sledge, out of 2 inch diameter logs, that I can tow behind the ATV.

Larger rocks simply don’t let the sledge move but these can be rolled by wrapping a chain around the bottom of the rock using the grab hook and then pull the chain over the rock to roll it several metres (yards) at a time with the ATV. This will not work for flat shaped rocks of that size.

A Review of Viabililty of Commercial Thinning of the Bush

At the Confer Management Workshop, I became acquainted with a Forester/consultant who seeks out woodlots for commercial thinning. He gave one of the talks at the workshop. I approached him indicating that according to my Managed Forest plan that I am due for a thinning.

He came by today to examine the forest. The assessment that he gave was that the white spruce (Sw) plantations were probably eight to ten hears away from a first thinning. The red pine (Pr) is ready for a thinning but there is not a large enough plot to make it commercially viable.

Both the Pr and the Sw were planted at the same time yet their growing behaviours are quite different. The Pr will grow at a continuous rate regardless of the conditions while Sw will tend to slow down when the conditions are poor such as poor soil, poor drainage or poor light. Hence Sw also tends to be self-thinning.

The forester recommended that I thin out the Pr and especially take out the damaged trees. Many of the Pr were damaged by porcupine which caused the trees to grow into “Y” shapes.

Fletcher Wildlife Garden Visit in Ottawa

In the interest of learning to be able to definitively identify two very invasive plans I visited the Fletcher Wildlife Garden in Ottawa to see the live weeds. In particular I was curious to learn more of the “dog strangling vine” or Black swallow-wort [Cynanchum nigrum] and the Garlic Mustard [Alliaria petiolata]. The garlic mustard was pretty well under control through active volunteer weeding programs, however the swallow-wort situation was another story. According to my colleague, at the FWG this weed is actually pale swallow-wort[Cynanchum rossicum], not black, and it has literally taken over the forest floor. I was personally amazed to see such a phenomenon. It has completely choked raspberry bushes for example, and is even taking over tall standing grass. The term “dog strangling vine seems to be applied to either species (Black or Pale) of Swallow-wort. Pale swallow-wort has become a major problem in up state New York as described at this website: http://www.swallow-wort.com and also in Ontario such as the Don and Rouge Valleys in the middle of Toronto.

I arrived on time today to be volunteered to weed some garlic mustard, which I did willingly. Identifying the plant now is pretty well ingrained. I do not yet know of any occurrences of these weeds on this property and feel confident that I will now be able to identify either weed at a glance.

Visit of the Vultures

Today we were visited by turkey vultures [Cathartes aura]. They are quite impressive and graceful at soaring. I had read some time back that vultures have a keen sense of smell, especially of decaying flesh. Yesterday I had found the decaying carcass of a starling under some tin sheets left from an old barn that had collapsed. I had uncovered the tin from the carcass so that it remained visible to the open air. To think that the vultures were able to smell this small carcass even when there is a reasonable breeze. Quite extraordinary I would say. As soon as they spotted me they left after some low level hovering.

I wonder if they ever located lefty’s carcass?

I have been an active birder back in the late 60’s and early 70’s and at that time the turkey vulture was unknown in these parts and yet now they are quite common here. In fact the older bird books that I have such as BIRDS OF NORTH AMERICA, by Robbins, Bruun, Zim and Singer [1966] (ISBN was not yet available at time of printing), clearly shows that this bird did not venture north of Lake Ontario in the east. A newer book entitled FIELD GUIDE TO BIRDS, EASTERN REGION by Donald and Lillian Stokes, [1996] ISBN 0-316-81809-7 shows the turkey vulture ranging this far north.

This phenomenon is also noticeable in other bird species. Hello to global warming.

Workshop on Conifer Plantation Management

April 16, 2005

The Ministry of Natural Resources through the Ottawa Stewardship Co-ordinator put on this one-day workshop at the Fred Barrett Arena in Gloucester Ward. The City of Ottawa Municipality also sponsored the event. It was a good opportunity to meet some local woodlot owners or persons interested in woodlot management. Through casual contacts I was made aware of an interesting supplier of machinery that might ideally suite my scale of operation.

This workshop covered many of the basics of woodlot management, and like any event there is always something new to be learnt.

The programme ran from 8:30 to 15:00 hrs:
1. Introduction to Plantation Management – Gleaned titbits; the bible of silviculture management is available from www.mnr.gov.on.ca entitled: Silviculture Guide to Managing Ontario Forests for a very reasonable $25.00. The Ontario Woodland Improvement Act or WIA operated from 1967 to 1995. Our property was planted through that program in 1973. The first thinning should occur in 25 to 30 years. Thereafter subsequent thinnings are to occur every 8 to 10 years. It is proposed that every fourth row be removed and every 5 or 6th tree in adjacent rows.

2. Forest Operations – Titbits; when hauling trees out to minimise collateral tree damage, cut trees to 16 feet (4.88 M.) before hauling them out that is don’t pull out full-length trees.

3. Timber Sales and Marketing – Titbits; there are three types of tree sales: Stumpage, Roadside, and Delivered. Stumpage is the sale of the uncut tree; for Roadside the trees are stacked ready for pickup by the buyer; and then Delivered means the transaction is at the sawmill. Stumpage is usually priced per unit or at a lump sum. As good fences make good neighbours, good contracts make good friends.

4. Biodiversity and Wildlife Values – Human impact will reduce more species in the next 25 years than natural selection during the last million years. To encourage biodiversity thin plantations near hardwoods first.

5. Field visit by bus: conifer plantations to be thinned and/or recently thinned) Visited three plantations in various states of management.

American Woodcock on Soggy Ground

Last weekend there were patches of bare earth peaking out through the snow. This weekend we have a few patches of snow remaining on bare earth. The last 24 hours we have had a very intense rainfall estimated around 2.5 cm (1. In.) in a day and this deluge has contributed considerably to the disappearance of the snow.

In my short walk today I flushed out an American Woodcock, [Philohela (1) minor (old scientific name) Scolopax (2) minor] a very orangy-brown coloured bird in flight. It was interesting to flush out something other than the usual ruffed grouse. The ground was quite soggy everywhere throughout the forest floor other than those few patches where there was still some ice and snow on the ground. The streams are all overflowing. The fields in the adjacent lots are completely flooded in many cases. For example one field west of here in the next concession, is a solid lake. The Canada geese will come down into these fields for a stopover. At night you can hear the cacophony of honkers. There are also several small coveys of pintail ducks.
