Storm Proofing Your Trees

Storm Proofing is Important For Your Trees

The aesthetic financial and social value of trees can all be lost in the event of a storm. So it’s important to have storm-proofing for trees. Snow, ice, high-velocity winds, tornadoes, and hail are some of the natural perils. Some trees can be damaged partially while some sustain injuries that cannot be treated to regain their health and value to a property. Depending on the strength and intensity of a storm damage can range from minimal to intensive. Damaged trees are a source of concern to the people in the surrounding.

Making the right decisions after a storm is a critical process. The assistance of experienced arborists can help determine whether a tree requires removal or treatment. Under normal weather patterns, trees condition themselves to withstand winds and lightening storms. They adjust their growth to cope with external loading. However, hurricane-force winds can destroy entire forests. These damaged trees pose risks to personal safety as well as the safety of adjacent properties. Despite the impact that these storms have it is important to still consider the numerous advantages that trees have. Trees in a compound add beauty, moderate the elements of weather and increase property values.

Research has been conducted after previous storms on ways to storm-proof your trees. They have provided valuable knowledge on why and how trees fall when hit by a storm. This article targets individuals who wish to develop knowledge to grow more storm-resistant urban forests to minimize the impact of future storms.

Common injuries sustained after a storm.

Failing of the stem: External forces such as strong turbulent winds take advantage of the weak points in a tree. Trees are likely to crack or snap at these points of weakness. Weak points can be caused by previous injury points or areas where the tree was exposed to a disease or insect infestation. The damage from stem failure is mostly beyond repair. It is, therefore, necessary for an arborist to assess a tree and give recommendations to avert disasters.

Branch failure: Poorly attached branches are often the prime target of strong winds or storms. Accumulation of ice or snow on branches also cause loading on branches which often leads to breakage. Damage to branches is usually not lethal to trees unless damage of the crown is above 50 percent. However, these branches pose serious safety issues. It is imperative for a landowner or manager to learn to recognize signs of damage like death breakage or hanging limbs to reduce risks. The assistance of a certified arborist is often needed as damage branches can be hard to identify and require close inspection.

Twisting of the crown: Uneven crowns can result due to poor pruning techniques. Uneven wind loading causes a twist on the array of leaves, branches, and twigs that constitute the crown. Twisting leads to cracking around areas of weakness like old wounds. This often leads to failure.

Other effects of storms include uprooting of an entire tree This occurs when the wind loading in the aerial part of the tree weighs heavily on the root system. A number of factors like decays and pest attacks predispose a tree to poor anchorage and health which in turn makes toppling by winds easy. Trees that do not fall over during storms can sustain huge stresses on their root system. Roots that are damaged or diseased can cause a tree to lean and fall.

What are the mitigation methods?

Studies have shown that;

Trees growing individually are hardest hit than trees growing in groups. A group can be defined as five or more trees growing within ten feet of each other but not in neat rows. Planters should ensure good spacing between trees to encourage the growth of a vibrant and strong root system. Planting trees in groups of five or well-spaced clusters is recommended.

Some tree species resist strong winds better than others. wind resistance is the ability of trees to withstand hurricane force winds without easily uprooting or breaking. It is recommendable to plant species that have been shown to more wind resistant. Planting different varieties, ages, and layers to maintain diversity is also recommended.

Old and hazardous tree species that have demonstrated poor survival should be considered for removal. Such trees pose danger to people and property. Certified arborists can be contacted to give advice on the resistance ability of various species.

Tree Trimming – Coquitlam

Tree Trimming – Coquitlam

There are several different types of hedge cutting that can be done around a customer’s home. Standard tree trimming consists of removal of all dead wood from the tree, elevating the canopy so that it is not touching the roof, hitting your head when you mow, raise within city guidelines over the street or sidewalk, selective thinning of the sprout on the inside, correction of stubbed limbs or previous breaks and looking to remove crossover limbs as well.

Tree pruning that is not done correctly can cause damage that remains for the life of the tree.

Ball Moss Removal:

Ball Moss removal is a standard part of tree trimming/pruning as well. Ball Moss is not harmful to the tree (as it is an epiphyte) but it can be unsightly and therefore undesirable.

Roof Clearance:

Tree trimming to raise the roof is a minimum cost type of job that will keep limbs from touching the house.

Crown Clean-out:

Pruning of dying, dead, limbs that cross or intersect, weak attached limbs and sprouts from a tree’s canopy. This is one of the most common tree trimming procedures.

Crown Elevation:

Tree pruning that is done to raise the lower limbs of the tree to provide clearance for driveways, walkways, homes, buildings and/or to be able to walk under.

Crown Reduction:

Pruning back leaders to lateral branches to reduce height and/or width of the tree. This is only done only as a last resort to having to remove the tree. An example of this would be when a tree is growing under electrical lines or to provide a view over the top of the tree.

Vista Pruning:

Tree trimming in which the homeowner would like to create a view or a business would like for his or her sign to be seen more clearly. Cabling/Bolting:

Tree cabling is the installation of high strength cables and/or threaded rods to increase structural strength in the tree. This is done with limbs growing at bad angles, co-dominant limbs with included bark, limbs that have split and would like to prevent further cracking therefore the cables are installed to restrict movement and to take weight off the attachment that is splitting.

These are the only cuts that should be made during tree pruning:

  • Trimming dead or decayed branches that could be hazardous to person or property
  • Trimming diseased and insect infested limbs (This prevents or slows infestation into healthy parts of the tree)
  • Trimming of limbs or branches damaged by high winds and/or storms
  • Pruning branches that touch wires, homes or buildings
  • Sprouts can be removed to thin the tree allowing air to flow through the tree and light to shine on the yard so that grass can grow properly
  • Training of new trees for future shape and structure
  • Pruning excessive weight on the tips to reduce the chance of limbs breaking in the future
  • Trimming of crossover limbs that intersect and rub against each other leaving the tree open to pathogens

The Importance of Bees in Coquitlam

The Importance of Bees in Coquitlam

Information about how the bees are gradually depleting in their numbers has most likely got around to everyone. I think there might be a misconception that they only pollinate flower bearing plants, however that is not true. Bees also pollinate trees despite them mainly being pollinated by the air.

Imagine how few trees and other plants there would be if bees didn’t exist. Forests are unlikely to be the same if they were never present. Insects that pollinate are incredibly important to the upkeep of plant communities and their ecosystems.

Trees are a common habitat for bees surprisingly enough. They don’t only create their hives on the branches that we so commonly see and exterminate. The majority of bees have a variety of locations that they usually inhabit while they are not out pollinating. In a previous article, we talked about how insects have different eating methods. One of these specific eating methods results in the bees having a home.

Bark beetles bore under the bark during their lifecycle. Bees have found these cavities to be rather comfortable when they are looking for a spot to nest. So, despite how devastating some of these insect attacks can be, they do serve their benefits. On the other hand however Bumble Bees nest in abandoned rodent holes, whereas feral bees resort to hollows in trees. Like any other animal, bees use a variety of materials to create their nests.

Trees pollen carries the male genetic material. You can usually notice tree pollen around spring time; it’ll have a yellowish cloud of granular material. Interestingly enough, those of us that suffer from allergies in Coquitlam now know that when pollen in inhaled by chance that is actually what causes our unpleasant allergies. However, this cycle of airborne pollination is what trees need in order to continue striving and evolving in their environment.

Airborne pollination does depend on the location of the tree. If it is higher up on the latitude and elevation scale then it’ll have a better chance of getting pollinated by the wind. On the other hand though if we were reporting out of a rain forest it would be a different story. The pollination there relies more on the help of animals, specifically the insect variety.

Wind pollination is the most productive in open areas. However, although the trees with cones and flowers that are exposed to the wind do get pollinated at a likelier rate, the flowers that are growing under this range aren’t getting very much help from the wind when it comes to needing to be pollinated.

Both conifers and broadleaved trees have an easier time being pollinated by the wind. Additionally, the trees that rely solely on wind pollination tend to expel an excess amount of pollen in order to successfully fulfill their pollination quota.

This may seem like a good strategy, but realistically it isn’t. Although some pollen has the ability to travel a long distance, the reality of it is that most of the pollen particles end up resting close to the tree that released it, to begin with.
