The brushy hillsides and grassy fields of our community present the potential
for a major wildfire. The mix of wildland fuels and homes creates a tremendous
fire problem. Fires do not happen only in Southern California and the
Oakland Hills; they can and will happen here.
We know that you have spent a lot of time, effort and money in your landscaping
and we at Wegman’s want to be active in keeping our community safe.
In the next few editions of the newsletter we will feature articles that
give you tools and information to help protect your homes and property
from wildfires.
Firescaping revolves around three ideas: Clean landscapes, healthy plants
and ample space between clusters of plants. Three major factors affect
the fire danger level. These factors are the fuels, the topography and
the weather.
Fuels include grasses, heavy brush and trees. The danger
that these fuels present is directly proportionate to the moisture level
in the fuels. With the recent hot weather the moisture content in fuels
is extremely low.
The topography factor: the steeper the grade, the
greater the danger. Fire will move quickly uphill and may ignite houses
on ridges and hills.
The weather factor is the only factor over which we have
no control. Long, dry heat waves like we have been experiencing will dry
out and preheat fuel. High winds will increase the speed at which fire
moves and the intensity with which it burns.
A small fire can become a catastrophic event in a matter of minutes, but
there are precautions that can be taken to minimize the effects of a wildland
fire. Wise landscaping is something homeowners can do to help protect
their homes.
A mature landscape is more flammable than a juvenile one. Young and rapidly
growing plants and landscapes have growth and limbs that are moist, supple,
and low in fuels. A garden that was planted 50 years ago may require removal
of some, if not most, of its plants.
Fire retardant and fire resistant varieties of plants are available.
A fire-retardant plant is reluctant to bust into flames. These plants
are typically fleshy, moist, and broad-leafed; trees and shrubs are deciduous.
They are used close to a house to protect it from flying embers and intense
heat. Because of their nature, fire retardant plants may need more water,
fertilizing, and maintenance. Species in this group would include Festuca,
Geranium, Gazania, Vitis, Syringa, Acer and Liquidambar.
The next zone of plants around a home should be fire-resistant. These
plants may be able to slow or even stop a fire, and tend to resist the
effects of the fire better than other plants. If they catch on fire, they
do not hold it long, because they do not possess a lot of fuel. Fire-resistant
plants also may resprout or germinate after a fire, which are ideal qualities
on slopes. Fire resistant plants tend to be lower maintenance and require
less water. Some of the species in this group include Ceanothus, Gaultheria,
Encelia, Mahonia, Romneya, Gelsemium and Quercus.
The ongoing process of removal and replanting helps create healthy, fire
retarding gardens, but it is just a part of firescaping. Design ideas,
building materials, watering methods, pruning techniques and erosion controls
are important too.
