2011 National Forest Week September 18- To 24

To make your home more FireSmart, you should store your wood pile 10m from your home to prevent it from catching fire easily. Additionally, removing all long grass, shrubs, branches, twigs, and needles 10m from your home helps to create a defensible space and reduces the risk of fire spreading. Pruning the first 2 meters of branches on tree trunks around your home also helps to prevent fire from climbing up the trees and reaching your home. Therefore, all of the above actions should be taken to make your home more FireSmart.

Dendrochronology is the science of calculating a tree's age by counting the tree's rings. Each year, a tree forms a new ring in its trunk, and by counting the number of rings, the age of the tree can be determined. This method is based on the principle that each ring represents one year of the tree's growth. By examining the width and characteristics of the rings, dendrochronologists can also gather information about past climates and environmental conditions. Measuring the height, diameter, or counting leaves of the lowermost branches would not provide accurate information about the tree's age.

Wildfires do play an essential role in maintaining the health of northern forests and ecosystems. They help to clear out dead vegetation, promote new growth, and recycle nutrients back into the soil. Additionally, some plant species have adapted to rely on wildfires for their reproduction and growth. Therefore, it is true that wildfires are important for the overall health and balance of northern forests and ecosystems.

Xanthan gum is not an example of a non-timber forest product harvested in the NWT because it is a polysaccharide commonly used as a food additive and thickening agent, which is typically produced through fermentation of a sugar source, rather than being directly derived from forest resources. On the other hand, Birch sap, Morel mushrooms, and Berry picking are examples of non-timber forest products that can be harvested in the NWT for various purposes such as food and medicine.

Caribou is the preferred food source for lichen. Lichen is a type of organism that grows on rocks and trees, and caribou feed on it as a major part of their diet. Lichen provides caribou with important nutrients and energy, especially during the winter when other food sources may be scarce. Caribou have evolved to have specialized digestive systems that allow them to efficiently extract nutrients from lichen, making it their preferred food source.

Sphagnum moss was traditionally used for lining a baby's diaper.

The inside of a tree is made up of xylem, phloem, and cambium. Xylem is responsible for transporting water and nutrients from the roots to the rest of the tree, while phloem transports sugars and other organic compounds from the leaves to other parts of the tree. Cambium is a layer of cells that produces new xylem and phloem, allowing the tree to grow in girth. Therefore, all of the options mentioned are correct.

To protect your property from wildfire, it is suggested to begin by FireSmarting the first 10m around your home. This involves removing any flammable materials such as dry leaves, dead plants, and debris from this area. It also includes trimming tree branches and keeping the grass short to reduce the risk of fire spreading towards your home. By creating a fire-resistant zone close to your home, you can significantly decrease the chances of your property being affected by a wildfire.

The correct answer is Montane Plains. The question is asking which ecoregion is NOT found in the NWT (Northwest Territories). The NWT is known for its vast wilderness and diverse ecoregions. The Taiga Plains, Taiga Shield, and Cordillera are all ecoregions that can be found in the NWT. However, the Montane Plains ecoregion is not found in the NWT.

The correct answer is 9%. This means that 9% of vascular plants in the NWT are alien species that have negative impacts.

An acre of trees can absorb a significant amount of carbon dioxide through the process of photosynthesis. This process helps to reduce the amount of carbon dioxide in the atmosphere, which is a major contributor to climate change. The given correct answer of 14,000km suggests that an acre of trees can absorb as much carbon dioxide as is produced by a car driven up to a distance of 14,000 kilometers. This highlights the importance of reforestation and the role that trees play in mitigating climate change.

Larch is the correct answer because it is known for its durability and strength, making it an excellent choice for fence posts. Larch wood is naturally resistant to rot and decay, which helps it withstand outdoor conditions for a long time. Its dense grain structure and high resin content also contribute to its sturdiness, making it less prone to warping or splitting. Overall, larch is a reliable option for fence posts due to its ability to withstand pressure and environmental factors.

Balsam poplar leaves, when chewed and applied as a paste, help soothe pain from a bee sting.

Larch provides the greatest amount of heat in terms of BTUs.
