Preservation during construction is
crucial to soil preservation, microbes and tree survival. Unfortunately
landscape preservation prior, during and post construction activities
are often overlooked. Construction activities can physically damage
trees and the soil which, they depend. Whether it is a commercial
or residential site, ignoring potential soil and tree damage can
be very costly. In many cases tree preservation hinders contractors
and projects take more time. Weighing the cost to preserve soil
and trees make the most economic and aesthetic sense before construction
begins.
Injuries from equipment that scrape tree bark are very common.
Most tree species can compartmentalize small wounds with little
affect to tree health. The most critical injuries are unseen and
below ground. The most important destruction by construction activities
is the almost irreversible damage to the rhizosphere. Soil is not
only this nations most important resource, it is non-renewable.
The rhizosphere is the absorbing root-soil interface. This is the
area of soil occupied by roots, arthropods, earthworms, protozoa,
slime molds, algae, nematodes, bacteria and fungi. These micro and
macroscopic organisms and their interactions are vital for a trees
survival. Trees in newly compacted soils usually die. Since trees
store energy and budget water use they may appear to be alive for
several years, but in fact are standing dead.
Trying to remedy construction damage after the fact is challenging
and often a lost cause. Preventing damage to soil and trees is the
key. Deciding whether or not to keep a tree is an important consideration.
Many times trees are too close to construction and if damage is
inevitable, remove the tree. Preservation is not limited to existing
trees. Preserving soil for new trees is also important. Damage to
soil structure can create an unsuitable site for new landscape plants.
Our tree preservation programs are custom tailored to the individual
needs of each site. Consultations are performed by one of our consulting
and certified arborists to view construction plans to determine
areas to be preserved. Then we will talk to designers and homeowners
to decide course of action. Designated work areas and storage sites
are then determined. Tree protection zones are established and fenced
off to keep contractors and equipment away. Top soil may in fact
be stripped in certain areas, so it can be placed back, texture
and tilth intact Rules are established identifying, expectations,
penalties for violating protection zones, practices, procedures
and standards for any pruning, planting, or utility installations.
