Woodlot Management & Tree Selection

The final 2011 Nature Quest Workshop was held on July 26th at the Bracebridge Resource Management Centre. Stewardship Coordinator, Chris Near, from the Parry Sound Muskoka Stewardship Network (PSMSN) led the session about Silviculture.

What is Silviculture?

Simply put, silviculture is the science of growing trees. If you are a woodlot owner, chances are you will want to think about which silviculture method you would like to practice in your woodlot. You may even end up practicing more than one depending on the size and features of your property. Chris spoke to the group about three methods for growing, harvesting, and regenerating trees: clearcutting, selection, and shelterwood.

Plantations, such as the red pine plantation pictured above, require good forest management, including proper thinning, top reach their full potential. Red pine prefers dry locations and grows best on sandy, coarse loam soil which is well drained. Research has shown that as red pine plantations mature, they begin to transform old field sites into forest conditions. The increase in organic material in the soil from the needles helps prevent erosion from wind and water. As the stand is thinned, the increase of sunlight reaching the forest floor provides ideal conditions for native hardwood and conifer species to germinate and grow.

About 50 bird and mammal species depend on cavity trees, including primary users which make their own cavities. Cavities constructed by the pileated woodpecker (like the ones above) are especially important in providing habitat for other animals. Aim to keep six living cavity trees per hectare in our woodlot.

If you are planning a large cutting operation on a large woodlot, be sure to consider how the logging equipment will get in and out of your woodlot. There is the potential for damage if not thought out properly. Some landowners will use the trails made by the skidders and other logging equipment and convert them into trails for personal use after the logging is finished (like in the photo above)

Creating openings in the forest crown provides benefits to regeneration. You might consider planting seedlings in an opening to promote greater species variety. Make sure to consider species types and their shade tolerance and plan for maintenance of the area if necessary to maintain sunlight in the area.

The Bracebridge Resource Management Centre (BRMC) is a great place to visit to see the different aspects of forest management. It is indeed a managed forest where the Ministry of Natural Resources (MNR) has managed different parts of the forest there in different ways and to regenerate the forest using different methods. If you get a chance to visit, make sure to stop at the signs like to one above to learn about various aspects of silviculture.

Batty About Bats

Bats are the primary predator of night-flying insects such as moths, beetles, and mosquitoes. Did you know that a single bat can catch hundreds of insects in just one hour? That can mean consuming from 30 to 50 percent of its body weight in insects each night!

Christy Macdonald, Fish and Wildlife Technical Specialist at the Ontario Ministry of Natural Resources joined us for the third Nature Quest workshop of the summer to tell us about bats in Ontario and some of the challenges they face. Here are some of the highlights from the afternoon.

There are eight different species of bats in Ontario. Can you name them? Above is the big brown bat. Below, is the tri-coloured bat.

There is also the Hoary bat, the Eastern Red bat, the Silver-haired bat, the Northern Long-eared bat, the Eastern Small footed bat, and the Little Brown bat. Ontario's bats are a mix of cavity and foliage roosters. Cavity roosters roost in caves (or sometimes bat houses) in large numbers and hibernate over winter. Foliage roosters don't form colonies but instead live singularly in trees. The Eastern Red bat, the Hoary bat, and the Tri-coloured bat are all foliage roosters.

One serious issue Christy spoke with the group about is white-nosed syndrome. The Little brown bat above has the outward physical signs of this white fungus which first appears on the nose and face areas and has since spread the the wings. This fungus deteriorates the skin on these areas. There is not much known about this fungus that has only appeared in Ontario in the past year. It is only present in the colonies as they hibernate. Internally, the white fungus seems to cause strange behaviour in bats, such as waking up during hibernation. When they wake up they want to clean themselves of the fungus which uses their crucial energy stores. Sometimes infected bats will spend even more energy looking for food during the day-time or in winter. This is bad news, as these bats end up using their stored energy and dying of starvation.

What can you do to help? Don't go into caves or abandoned mines. And don't touch live or dead bats. You can also report sightings of bats with white-nosed syndrome by calling the Canadian Cooperative Wildlife Health Centre at 1-866-673-4781.

Bat houses are another way we can help bats by creating habitat for them. There are many factors to consider when building a bat house:

1. Design & Construction



2. Habitat (in Muskoka, near water is a must)



3. Sun exposure (full sun, and paint the box black)



4. Mounting (predator guards, not on a tree)



5. Away from predators (like racoons)



6. Away from uninvited guests (like wasps)



7. Timing (fall is the best time to put up a bat house)



8. Experiment (if bats don't visit, try another location)

You will need to do some research about the specific design and construction. Some helpful links to resources are below. I would love to hear how you fare!

Species at Risk in Muskoka: A guided walk of Torrance Barrens

For our 2nd Nature Quest workshop of the summer we gathered at Torrance Barrens to learn about Species at Risk in Muskoka. Torrance Barrens is a Conservation and Dark Sky Reserve established in 1999. The 1905 hectares is a region as a protected pace free from intrusion by urban light pollution. Its' rugged barrens, wetlands, and forested areas also provide habitat to at least 5 of Ontario's Species at Risk.

Natural Heritage Biologist Jan McDonnell led the group on a hike around Highland Pond and spoke to us about the valuable habitat the area provides and the species who call Torrance Barrens home.

Above: Here's Jan telling the group about turtles that are known to live in Torrance Barrens. Spotted Turtles have been seen here before and Blanding's turtle habitat exists here.

Above: a Spotted turtle, a species at risk classified as endangered

Above: a Blanding's turtle, a species at risk classified as threatened

Above: Participants in the workshop cross the bridge over the wetland. Wetlands are one of Muskoka's most valuable habitats. They provide many services like filtering the water to maintain water quality, help prevent erosion, and help control floods. Many species also depend on wetlands for habitat and food.

Above: Jan passes around a turtle shell and a snake skin for participants to look at as she speaks about suitable habitat for snakes such as Massassauga rattlesnakes and Eastern Hog-nose Snakes.

Above: Massassauga rattlesnakes (threatened on the species at risk list) use large "table rocks" as gestation sites. It is here that they give birth to live young every 2 years. It is too energetically demanding to do every year. The table rocks are used to thermoregulate; hide in the shade under the rocks or between the rocks when it's hot and lay on top when they need to absorb heat.

Above: Eastern Hog-nosed Snakes eat toads and tend to roam over vast areas in search of toads, open sandy areas & dry woods. They lay eggs under a log or in leaf litter in midsummer. Their eggs hatch after about 2 months.

Above: In a dramatic fashion, the Eastern Hog-nosed snake will play dead (and even hand its' tongue out!) as a defence mechanism. They are also known to "puff adder" to intimidate potential prey, although they are not dangerous. They are categorized as threatened on the species at risk list.

Above: At our last stop, Jan talks about the poor fen wetland in Torrance Barrens. Poor fens have a high water table and some flow-through, but not much fresh water. They absorb massive amounts of water and are exceptional at preventing floods, supplying a constant flow of water and water filtration.

Above: The Whip-poor-will is a nocturnal bird whose habitat can be found in Torrance Barrens. They like a mixture of open (for feeding) and wooded (for nesting) areas. Whip-poor-wills call at dusk and just before dawn and their name take after the sound of their call. They are also a species at risk, categorized as threatened.

The Five-lined Skink is Ontario’s only lizard. Juveniles have a bright neon blue tail (grey in adults as above). Skinks are active during the day and like wooded locations with sandy soil and open rocky habitat with crevices and loose rocks. They lay 6-10 eggs under a log or rock which hatch in late summer. They are listed as a species of special concern on the species at risk list in Ontario.

Watch for turtles out on the roads this season!

Tree ID in Muskoka

It's that time of year again! The Nature Quest Stewardship Series is in full swing. Join us every Tuesday in July as we learn about tree identification, species at risk, bats, and forest management.

Participants look in their field guides and they identify a tree as part of the first Nature Quest workshop of the summer.

This week, the topic for the workshop was "Hike up your tree ID IQ". You might remember a workshop with the same title from last year. The new Stewardship Coordinator at the Parry Sound Muskoka Stewardship Council, Chris Near, refreshed the program this year and enthralled the audience in an afternoon hike at the Bracebridge Resource Management Centre.

Chris helped to give us the tools we need to become tree ID experts. Here he helps a young participant identify some needles from a coniferous tree.

Chris helps some of the participants note the differences between the leaves of hard and soft maples.

We started off with a list of ways that trees can be identified:

Coniferous or Deciduous

Coniferous are cone-bearing and have needles. Deciduous have leaves.

Bark

What colour is it? Is it rough or smooth? Does it peel? Is it hard or soft? Each tree has a distinctive bark. This is a good way to identify deciduous trees in the winter.

Leaf Pattern and Structure

Are the leaves compound or are they simple?

Do the leaves grow opposite on each side of the stem or do they alternate?
Along the edges, is each leaf lobed, single toothed, or double toothed?

What is the shape of the leaf?

When there are no leaves on the trees, it can also be helpful to look at the pattern of the buds on the branch.

Needle Pattern

Are the needles clustered together? if so, in groups of how many? Or, are the needles single shoots off the stem?

Silhouette

What is the silhouette of the tree when you stand back a little but and look at it? Round, pointy, bushy? This can offer a hint as to the species of the tree.

Fruit

Is the tree bearing any fruit? What does it look like? What shape is it?

My list above is very brief and uses only words. It's a good idea to find a field guide to help you with your tree ID. There are also some good websites to help you along. Some suggestions are at the end of the blog. It's also a good idea to go for hikes to practice your tree ID. After all, practice makes perfect! Good Luck!

Participants walk along the trail and the Bracebridge Resource Management Centre. It was a beautiful day for a hike as we identified trees.

Wildlife CSI

The last Nature Quest Workshop of the summer was put on today by John van Geene, Conservation Officer (C.O.) for the Ministry of Natural Resources. He spoke to the group about his job and the world of wildlife forensics. There were lots of skulls, pelts, and antlers on display and we spent some time outside in mock situations of examples of what John encounters when he is out in the field.

{John, in uniform with duty belt and the equipment he uses on the table behind him}

The job of a Conservation Officer is a tricky one. It involves the art of interacting with people and educating about why the laws are in place and how they are designed to help the natural world. It also means upholding the fisheries, hunting and land use laws on crown land and encouraging people to comply with these laws. The job of a conservation officers is mostly reactionary to tips called in by the public (1-877-TIPS-MNR). Officers also patrol throughout Parry Sound Muskoka district during moose and deer hunting seasons.

{moose skulls, antlers, and jawbones- the teeth are huge!}

For example, if a hunter has a tag to kill a cow moose, but instead kills a bull and is caught by a C.O. they could be fined and will most likely have the animal confiscated (the meat is donated to food banks). At the workshop, John explained that moose tags are issued based on a lot of research done on the moose population of Muskoka each year. There are different wildlife management areas in the province and the number of tags for bulls and cows depends on how strong the population is each year. John told us that populations can be threatened if hunters shoot more than they are allowed or not according to their tag. These laws exist to keep the populations stabilized. John reminded the group that humans are part of the natural world and the importance of balancing what we take and how our actions affect other animals and the ecosystem as a whole.

{a demonstration outside of a hunter who has a tag to kill a cow but killed a bull instead}

{John demonstrates the use of a live trap for raccoons as two workshop participants look on attentively- and test the trap!}

There is lots of fancy equipment that Conservation Officers use when they are out in the field and when collecting evidence to build a case against someone with an infraction. John had it on display for us. It includes:

• a duty belt (pistol, handcuffs, baton, etc.)
• walkie talkies
• binoculars
• spotting scope
• whistle
• compass, map & GPS
• satellite phone
• camera
• truck
• ATV

{John's truck with the ATV in the back. He even turned the lights on for us!}

Some of the most common infractions are:

• not having a licence (fishing or hunting)
• work on a shoreline that does not have a permit but requires one
• commercial sale of animal parts (e.g. bear paws & gall bladders)
• taking more than the allowable amounts (fish, wildlife)
• hunting or fishing for species that are not in season
• boating safety

John sees himself as an educator- of existing laws and their role in keeping a balanced natural environment. Adhering to these laws ensure that we are able to continue hunt, fish, and interact with the natural world. It is our responsibility to know the rules before heading out.

Hike Up Your Tree I.D. IQ

How is your tree I.D?

I brushed up on my tree I.D. yesterday as I attended the first Nature Quest workshop of the summer, along with a few of the Master Stewards. The workshop was hosted by Mike Walsh, Tree Marker Instructor and retired Stewardship Coordinator for the Parry Sound Muskoka Stewardship Network.

Together, the group walked through the unmanaged forest of Arrowhead Provincial Park examining the trees for species, defects, potential growing stock, cavities and mast. We examined 25 trees in total; each tree giving us different insight into its value in a managed forest situation.

My favourite are the trees that are ideal cavity trees. Cavities are little nooks or holes where an animal has dug or burrowed into a tree. Cavities are used as habitat or places to escape bad weather or predators. Cavity trees have a high wildlife value and tree markers recommend leaving 6 cavity trees per hectare in your forest where the tree is at least 25 cm DBH (Diametre Breast Height).

The best kind of cavity tree is called C1. These trees are at least 25 cm DBH and have one of the following:

• Pileated woodpecker nest cavities
• Pileated woodpecker roost cavities
• Swift roost cavities
• Other woodpecker nest cavities
• Natural nest or den cavities

The next best, or a fair cavity tree, also is at least 25 cm DBH and has one of the following:

• Escape cavities
• Feeding cavities on the bole or major branches

We also learnt about common tree diseases in Ontario like black bark, punk knots, spine tooth fungus, frost cracks, and sugar maple borer. Some trees are able to heal themselves from the diseases and can still be valuable to a forest. Other diseases have air borne spores and can infect neighbouring trees so it is best to cut them down.

I have lots of information and pictures about tree defects and forest management at the office. Of course, the Resources section of the blog is also a good place to start. Contact me or check it out!

Learn more about cavities on the Ontario Woodlot Association website.

Didn't make it out yesterday? There are more workshops in the series! Check out the blog posting from June 23rd called "Nature Quest Stewardship Series" for more information.

Nature Quest Stewardship Series

There are lots stewardship related events going on in Muskoka and elsewhere this summer. Check out the "Stewardship Workshops and Events" section of the blog and the "Events Outside of Muskoka" section on the right-hand toolbar.

In particular, I want to let you know about the Parry Sound-Muskoka Stewardship Network who is putting on some great workshops this summer. They are designed to provide hands on experience while fostering knowledge and understanding of land stewardship.
