During your travels through Lava Beds National
Monument you may notice areas of the landscape that have been charred by
fire. Some of these areas resulted from lightning-ignited blazes and
others resulted from management-ignited prescribed fire.
Wildfire is one of the most powerful forces of nature and is often
viewed in light of its destructive nature. However, within the last ten
to twenty years scientific research has enlightened land managers as to
the ecological importance of fire in wild ecosystems. One of the key
roles of wildfire is to maintain the diversity and health of plant
communities. This role results in positive benefits for a greater
variety of wildlife.
Periodic wildfires in Lava Beds once burned away plant litter and
undergrowth on a regular basis. As a result, most fires crept along the
ground and were not hot enough to damage the environment. Wildfires also
burned in a “mosaic” pattern, following fuel beds and natural barriers
such as lava outcroppings. This pattern left behind patches of older
vegetation for wildlife cover and opened up adjacent patches of ground
for the sprouting of new vegetation. New sprouts are much more
nutritious for wildlife and the patches of older vegetation provide
adequate cover for wildlife to access the new forage safely. The burning
of litter and undergrowth also recycles nutrients into the soil to
support new growth.
From the 1920’s to the late 1970’s all fires in Lava Beds were actively
suppressed. The traditional notion was that all wildfire was a "bad"
thing. Natural fuels present are unnatural and are at dangerous levels
that fuel very intense wildfires. These types of fires are difficult to
control and pose a greater threat to life and property compared to the
periodic ground fires that once burned through Lava Beds. The ponderosa
pines, like those near Mammoth Crater, are generally resistant to
periodic ground fires. Aging shrubs now provide an abundance of "ladder
fuels", a horizontal arrangement of plant growth that allows fire to
climb into the tops of large trees killing them completely. The lack of
periodic fire to burn away the under story has also inhibited the
regeneration of ponderosa pines in Lava Beds. Ponderosa pine requires
clear ground with minimal competition for nutrients and sunlight in
order to reproduce. Another example of fire’s importance to plants in
Lava Beds is bitterbrush, the primary deer forage in the monument. The
old growth provides excellent wildlife cover, but it is poor quality for
forage. Without periodic fire, clear patches of ground and nutrients are
not made available for the generation of new sprouts.
The fire management program at Lava Beds is actively engaged in
reintroducing the natural process of fire through two methods. The first
is known as wildland fire use and the second is prescribed fire.
Federal fire policy allows managers to evaluate natural fires
(lightning-ignited blazes) for their potential benefits to the
ecosystem. If weather and fuel conditions will permit natural fire to
burn at the proper intensity that will benefit rather than damage
natural resources, managers can allow the fire to run its natural
course. If threats are too great the fire may be suppressed entirely or
minimum suppression tactics may be used to contain the fire within safe
boundaries.
This program is known as wildland fire use for resource benefit
(formerly prescribed natural fire). However, it is difficult for nature
to catch up to man’s removal of fire from the landscape for such a long
period of time. For this reason fire management personnel prescribe fire
to treat unhealthy landscapes, just like a doctor prescribes medication
to treat illnesses.
Under weather and fuel conditions that promote resource benefits,
managers selectively ignite areas of the monument in an effort to reduce
heavy fuel loads and to reintroduce fire to the ecosystem. Reduction of
fuels helps managers to control wildfires, protect life and property and
makes necessary fire suppression efforts safer to conduct. The
boundaries around the monument and the developed areas, such as
headquarters and the employee housing units, are primary targets for
prescribed fire. This action reduces the potential for natural fires to
burn uncontrolled into or out of the monument or into developed areas.
Visitors should also be aware that all human-caused fires are
immediately suppressed because they do not represent natural processes
and do not benefit from the planning involved in wildfire use or
prescribed fire. Please do not leave your campfire unattended and do not
smoke on any of the trails. During a fire event, you may encounter smoke
and temporary trail closures. These inconveniences are only temporary
and are necessary for the benefit of our wild land ecosystems.
If you have any questions or would like more information about the fire
management program at Lave Beds, please visit the Fire Management Office
in the headquarters area or contact the office by phone at 530-667-8123.
If you would like to visit one of the areas where fire has been
reintroduced, fire management personnel will be happy to assist you.
Thank you for your support as we try to bring natural processes back
into the monument.
