Birds Love Native Trees

Illustration: birds flying around tree with fall colorsNative trees — species that are native to a particular geographic area — help protect water quality through their deep, well-adapted root systems that naturally increase the ability of soil to absorb, treat and retain water. These trees are also essential for supporting our region’s diverse bird populations. Native trees produce more insect prey for birds than non-natives ― and 96 percent  of birds raise their young on insects. They are crucial to preserving habitats, and can support 35 times more insect-eating birds than non-natives. Ever-increasing population density in cities makes it more important to consider the impacts of the built environment on wildlife habitats. To promote avian biodiversity, urban areas must be suitable for both humans and wildlife.

Because local insects did not evolve with non-native trees and plants, many lack the ability to overcome a non-native tree’s natural defenses and must feed elsewhere. Caterpillars, a fundamental food source for breeding birds, are one of the most specialized groups — over 90 percent of butterfly and moth larvae feed exclusively on certain plants. Currently, more than 80 percent of suburban areas are landscaped with Asian flora, leaving a food-barren environment for birds looking to find nourishment. When non-native trees replace native species, entire food webs can be disturbed by loss of adapted insects, wiping out sustenance for birds.

A study conducted through Smithsonian’s Neighborhood Nestwatch program found birds are more likely to build nests in yards dominated by native trees, and will fly farther to find grub if nest locations are not ideal. Although humans may find non-natives exotic and alluring choices for their landscapes, such choices can decrease birds’ survival and fitness, as many lack nutrient-dense seeds and fruit and may lure birds toward predators. Research by ecologist Amanda Rodewald found that chickadees nesting in invasive honeysuckle reared 20 percent fewer young due to increased predation during the breeding season. Non-native trees can be destructive to bird populations by disrupting natural selection.

Help protect habitats that allow birds to flourish by landscaping your yard with native trees. Birds, insects and many other species will thank you!

Celebrating Trees beyond Arbor Days

As petals from blooms speckle the pavement after spring showers, trees catch our eyes and our attention. But after the rich purples, deep reds and bright yellows have disappeared from our daily surroundings, will we continue to notice our trees, and think of all that they do for us? In both urban and rural areas, trees contribute significantly to human health and environmental quality by providing various ecosystem services (i.e., the conditions and processes through which natural ecosystems, and the species that make them up, sustain and fulfill human life).

National Arbor Day is observed on the last Friday in April. The state of Kansas will observe the holiday on April 24, 2015, while Missouri’s Arbor Day is April 3.

The Missouri Department of Conservation encourages residents to plant native trees. (See the tree selection and planting guide on the Missouri Department of Conservation website.) A state proclamation notes that trees are an integral part of Missouri’s quality of life:

  • Forests cover nearly one-third of the state.
  • Forests provide outdoor recreation, wildlife habitat, natural beauty, and watersheds for streams and rivers.
  • Forests provide employment for more than 33,000 people who convert trees into essential products.
  • Forests contribute beauty and shade to urban, suburban and rural areas while creating a more pleasant and healthful environment.
  • Missouri will continue to benefit from its forests for succeeding generations through tree planting and conservation.

 

“Assessing Urban Forest Effects and Values: the Greater Kansas City Region,” published by the United States Department of Agriculture Forest Service, lists a variety of ways that the MARC region benefits from its forests, including:

  • Water Quality: Tree coverage helps reduce total suspended solids found in streamways by natural filtration and reduces the amount of carbon in the atmosphere by sequestering carbon in new growth every year.
  • Air Quality: The urban forest improves air quality by reducing air temperature, directly removing air pollutants and reducing energy consumption in buildings (meaning less emissions generated from power sources.)
  • Stormwater Management: Increasing tree cover reduces stormwater drainage from both pervious and impervious areas.
  • Energy Conservation: Trees help conserve energy by shading buildings, providing evaporative cooling and blocking winter winds.
  • Carbon Removal/Storage: Trees in the Kansas City metro remove about 1 million tons of carbon per year (valued at $20.7 million) in addition to storing 19.9 million tons of carbon (valued at $411 million).

Remove 1 million more tons of air pollution each year. The study also found that increasing our tree cover by just 10 percent would:

  • Remove 3.1 million tons more VOC (volatile organic compound) emissions each year.
  • Sequester 9.4 million more tons of carbon each year.

Celebrating the value of trees


Look outside – do you see a tree or two? In Greater Kansas City, more than 249 million trees provide a wealth of services and benefits. From removing pollution and storing carbon from CO2 emissions (also known as carbon sequestration) to providing shade to lower cooling costs, each tree provides hundreds, if not thousands, of dollars in benefits to our region. It would cost tens of billions of dollars to replicate the benefits that our trees and forests provide to us virtually free of charge. In addition to the eco-services they provide, trees are also a natural source of beauty and provide shelter for both people and wildlife.What do trees do for you? Online advertising art.

MARC worked with professionals and scientists from the U.S. Forest Service, Davey Resource Group and SUNY College of Environmental Science and Forestry to publish “Assessing Urban Forest Effects and Values: the Greater Kansas City Region,” which takes a scientific approach toward calculating the value of our region’s trees. Some key findings show:

  • Trees remove 37,000 tons of pollution from our region’s air every year.
  • 1 million tons of carbon are stored within our trees each year through carbon sequestration.
  • The region’s 249 million trees save $14 million in energy costs annually.

Young girl holding sapling at City MarketTo draw attention to the findings of the report and help educate the community on the value of trees, MARC has given away more than 300 bur oak saplings and educational materials at area farmers markets. Bur oak trees are native to our region and can grow more than 70 feet tall and live for up to 300 years, all while cleaning our air, cooling our homes, and providing food and shelter to wildlife.
Consider planting a tree in your yard today. For information about proper tree selection and planting, check out Missouri Department of Conservation’s web resources. Visit our website for more information about the MARC’s Regional Forestry Initiative and to read the iTree report.
