A grand laurel oak,
damaged by Hurricane Matthew,
and plant
disease
|
As a lifelong Lowcountry resident my point of view as a
naturalist and amateur weather observer combine here I as revisit the aftermath
of Hurricane Matthew. Electing to ride out the storm on James Island at a
waterfront property, I surely had a front row seat to gauge the storm intensity
and to relay how a century old laurel oak was layed low, while surrounding live
oaks swayed without much ado. The legacy of Hurricane Matthew across the larger
Lowcountry landscape is similar with many laurel oaks damaged, while the live
oaks live on.

All
tropical systems have different characteristics, which serve to define their
legacy. Hurricane Matthew morphed into a Category One storm as it passed
through the Lowcountry, leaving a large surge of saltwater in its wake along
the coast. A wide swath of territory stretching
inland to I-95 saw ten inches of rain
and winds strong enough to topple many large hardwood trees, particularly in
swamps. No wide scale damage affected area pine trees, and the live oaks of the
Lowcountry proved again they are deserving of their accolades, bending but not
breaking.
But in the storm's aftermath, the Dennis family's grand laurel oak was dismasted and destroyed It’s long arms and natural cavities offered a home to a variety
of Lowcountry wildlife. Despite the injuries, we wanted to inquire about saving
the tree, and reached out to The Tree Clinic, specializing in sick and diseased
trees. Paul Mulkey
Jr. is a certified arborist and horticulturalist with The Tree Clinic, and when
he came out to assess the venerable tree, we learned how laurel oaks are
currently under stress across the Lowcountry. “Plant diseases are specific to
their hosts, and laurel oaks are being attacked now by basil and root rot
disease,” said Mulkey. “Phytophthora Cinnamomi is Latin for plant destroyer and
this begins in the tree roots and slowly progresses up the tree.”

“This is a soil born water mold, and not a fungus, that is
translocated into the tree,” said Mulkey. “What we are seeing is that during
periods of wet weather such as over the past three years this process is sped
up as trees utilize this natural resource. The inner wood vascular system
becomes clogged with the disease and begins to decline and die, and the rate of
healing for a large tree becomes less than the rate of decline.” In fact, when
we cut into the large limbs already on the ground, some of the inner wood was soft,
which also means it was no longer strong enough to bear the load of a far
reaching limb. The ultimate prescription was removing the damaged laurel oak.

It was the backside winds of the storm that caught many
large hardwoods by their canopy, and toppling them over. All corners of the
Lowcountry are reporting similar damage to bottomlands, and this will
ultimately be the legacy for Hurricane Matthew. While many large oaks are
already on the ground, this winter will see a fair amount of damaged limbs
coming down, so outdoor enthusiasts should keep safety in mind and keep an eye
to the sky while traversing the woodlands.
