Can a Tree Capture Particulate Matter from the Air?

For years, certified arborists and urban foresters have learned the many benefits of trees. Energy savings are one of the foremost known benefits of trees as they shade building during the summer reducing the need for air conditioning and deciduous tress allow sunlight to reach structures during winter months, solar radiation decreasing the need for winter heating.

Another known benefit for trees are their ability to reduce storm water runoff and erosion, particularly during the winter months. Tree root systems bind soil particles and slow storm runoff from roofs and other impervious surfaces, trees act as bio filters, slowing storm and irrigation water runoff and allowing the water time to slowly percolate into the soil profile rather than run off into the street or storm drain system.  By forcing water to pass through the soil profile, rather than runoff into storm drain systems, the soil mass filters impurities before the water enters into streams, ponds and aquifers.

What are the qualifications to become a “gardener” and turn that into a profession?
• A pick up truck.
• A lawn mower.
• A string trimmer.
• A blower. Continue reading “My Biggest Pet Peeve” »

It was just after Labor Day, while enjoying a walk through Morley Field, a portion of Balboa Park in San Diego; I came across an enormous limb lying on the ground beneath a 75′ tall Eucalyptus cladocalyx (Sugar Gum) tree.

Fortunately, no one was underneath the tree when this limb failed, or there could have been a catastrophe. Decades ago, when Balboa Park and Morley Field were created, Eucalyptus trees were heavily planted throughout park areas. They have since grown into towering, majestic trees, many greater than 100’ tall. The trees exist individually and grouped in stands of trees throughout the parkland area.

This post is part one in a series, click here to read part two.

For landscape contractors not familiar with the legal term “standard of care”, you need to understand the meaning and legal implications of NOT performing to the professional standard of care expected and common within the landscape contracting industry. Wikipedia defines the professional standard of care as “In certain industries and professions, the standard of care is determined by the standard that would be exercised by the reasonably prudent manufacturer of a product, or the reasonably prudent professional in that line of work. The standard of care is important because it determines the level of negligence required to state a valid cause of action.

This definition means if you perform landscape contracting services and your work product is found defective, deficient and or results in personal injury or property loss, you can be sued and found guilty in a court of law. The financial settlement will depend on the severity of the accident, property loss or injury. If you don’t think a lawsuit is a concern to your business, then you are most likely a candidate for a future lawsuit. Understanding your contractual and legal obligations as a licensed professional landscape contractor is paramount to protecting yourself and company from future legal action.
