I always have a list of maintenance activities that need to
be completed. When conditions prohibit
me from working on higher priority jobs, I spend time on one of the maintenance
list items. Tasks from the maintenance
list periodically get shifted to the priority list. One such activity is what I term Cedar
Maintenance, meaning that I maintain the open condition of a field by removing
young Eastern Red Cedars from the area.
It has been ten years since I have conducted Cedar Maintenance in some
of the prairie openings. I decided that
Cedar Maintenance needed to be brought up-to-date in order to prepare for
management activities planned for next year, so over the next few months I will
be searching for and removing young cedars from about 25 acres of prairie area.
In some of the harsher areas, cedars have managed to grow
only a few inches tall in ten years.
This small plant seems to have died back several times during the last
few years. Despite its small size and
the fact that it doesn’t yet pose a threat to surrounding vegetation, this
cedar is a target for removal. While
performing Cedar Maintenance, I remove any cedar that is large enough for me to
see.
The largest of the encroaching cedars was found in this
field. The ridgetop soils are a bit
deeper and provide a slightly better growing environment than the extremely
shallow soils on the slopes.
My medium sized loppers, now in their 25th year
of service, measure 26 inches from end of handle to blade tip. This largest of encroaching cedars topped out
at 30 inches. Had I planted this tree as
a landscaping specimen ten years ago, I would be terribly disappointed in its
rate of growth.
Checking the growth rings on the small cedar makes me think
that it is one that I missed cutting ten years ago. The age looks to be closer to 12 or 13
years.
It’s hard to maintain a precise search pattern in large
areas, so I use lines of orange lath to break the field into smaller units.
I then use rows of red and blue flags to break the units
into manageable search areas. After
searching each area, I move the back row of flags forward to form the next
area. When I finish with a field, I’ll
have seen every square foot of it.
I collect the cut cedars in bushel sized tubs and deposit
the cut material on top of old brush piles.
Piling the cedars requires slightly more time, but removing the cut
cedars allows me to clearly see that I have left no standing cedars in the
management area. This brush pile
contains the remnants of the cedars removed when the field was first
cleared. At one time the height reached
ten feet and I needed a short ladder to climb high enough to put more cedars on
top. The green branches in the back part
of the pile are some medium sized cedars that were cut from the edge of the
field. The smaller pile in the
foreground is from my current Cedar Maintenance.
This small pile, about two bushels worth, is composed of one
Virginia Pine and about 200 small cedars.
It represents cedar growth on about one acre of prairie. I spent two hours compiling this collection,
with a little of that time spent looking at interesting things discovered in
the field.
Cedar Maintenance generally requires that you be looking
down most of the time. Discovery of a
rather large collection of Autumn Olive leaves caused me to look up.
Emerging near the base of a mature cedar is the trunk of a
large Autumn Olive bush.
The Autumn Olive has grown straight up through the crown of
the tree. I watch for things like this,
but foreign stems hiding inside a cedar are nearly impossible to spot. Since rain was threatening, I marked the
invasive shrub with bright orange ribbon, so I could come back on a dry day to
cut and spray.
Leafy Autumn Olive branches don’t leave the security of the
cedar until they are well above the ground.
I take documentary photos each time I find a large Autumn Olive. My hope is to one day be able to show the
photo of the last mature Autumn Olive to be found at Blue Jay Barrens.
