TREES & the
Trees are a distinct part of habitat biodiversity. They
sustain vibrant ecosystems that support wildlife populations and
contribute significantly to bird, animal, plant, and insect diversity.
- stabilize the soil and filter polluted water.
- reduce cooling & heating requirements, resulting in conserved
- preserve and foster air quality by removing carbon dioxide
(C02) and airborne pollutants.
- abate visual and noise pollution.
- provide welcome shade and protection from UV rays.
- add color and interest to the landscape.
- Studies show:
- Trees provide a psychological boost to communities; people
are generally more satisfied with their neighborhoods if there
- Workers are more productive when trees are around their
place of employment.
- Hospital patients recover faster if they can see trees outside
How Heritage Trees support vibrant ecosystems:
Individual trees, groves, shelterbelts, avenues, and hedgerows;
- Help the soil to retain valuable moisture, not just around
the base but for a considerable area surrounding it.
- Bare soil directly exposed to rain has the potential for serious
erosion. Rainfall is a primary contributor to soil erosion.
Leaves help prevent erosion by intercepting and softening the
impact of the rain droplets. Leaf litter or organic mulches
further reduce the potential for erosion.
- The mixed age of stands and forests is an important criterion
in ensuring long term stable ecosystems.
- Trees affect the water cycle by reducing erosion and protecting
- Conifers planted on a slope can slow down the movement of
cold air that normally moves to low points, which prevents frost
- Often contain introduced species that have adapted to our
climate and survived, thus providing a valuable gene pool for
- Protection from soil erosion due to wind & water
- They act as a trap for winter snow to provide a valuable source
of spring moisture for crops, pastures, gardens and dugouts.
- Preserving wetland and riparian buffers on farms provides
valuable wildlife habitat, and helps to protect groundwater
resources while providing a measure of protection against drought.
- Farm shelterbelts and woodland habitats attract beneficial
insects or predators that feed on agricultural pests.
- Old trees provide long term ecosystem stability.
- Old trees contain genetic pools that have proven resilience
and health, providing established offspring that will continue
to support diversity for the habitats they reside in.
- Old growth forest serves as a reservoir for species which
cannot thrive or easily regenerate in younger forest, and as
such can be used as a baseline for research.
- Older trees provide more extensive root systems aiding in
the reduction of soil erosion.
- Old growth forests store large amounts of carbon, both above
and below ground. These forests collectively represent a significant
pool of climate gases.
- Some species of plants and wildlife can only occur where there
are old trees.
- Tall trees provide a layered canopy which supports diversity.
- One large tree provides climatic, energy and environmental
benefits equal to hundreds of new saplings.
Survivor of Adverse Conditions
- Trees with large canopies are able to process more CO2 and
release (transpiration) more moisture into the air. Thus helping
to reduce energy requirements for cooling.
- Larger canopies provide more soil retention, cooling and shade.
- Trees and plants control solar radiation. Leaves are responsible
for intercepting, reflecting, absorbing and transmitting solar
- Trees that have survived where others have not, contain genetic
pools with proven resilience and health. They can provide established
offspring that will continue to support diversity for the habitats
they reside in.
- Native Species that have established themselves in a region
not common to their natural range may be an indication of the
natural progression of forest succession. They are anomalies
worthy for their ability to grow outside their natural range.
