Pre-Conference Workshop • Sunday, December 8

The Urban Forest in New Orleans: Parks and Preservation

Travel with ASCA to City Park New Orleans and rotate through field stations the first part of the day. Afterwards, buses will bring participants to the Tree of Life at the New Orleans Audubon Park for a tour and to hear how staff manages efforts to preserve over 2,000 historic trees. Lunch in City Park will be provided.

City Park New Orleans, established over 150 years ago in the heart of the city, comprises a total of 1,300 acres and is one of the oldest urban parks in the country. It offers visitors the largest collection of mature live oaks in the world. Trees in the oldest grove are over 800 years old.

For more than a century, people have enjoyed Audubon Park, an oasis with allées of ancient live oaks, a tranquil 1.8-mile jogging path, a lagoon, picnic shelters, and playgrounds.

Mission Control: Invasive and Native Species Management
Whitney Wallace, LSU AgCenter
Ashley Long, Ph.D., Louisiana State University (LSU) School of Renewable Natural Resources

From early detection of invasive species to maintenance of wildlife habitat, urban foresters and arborists play a key role in natural resource conservation across diverse landscapes. Join us to learn more about common invasive plants and animals that occur in Louisiana and throughout the Southeast, including identification, strategies for minimizing risk of introduction and spread, and basic control methods for problematic species.

You’ll also receive information about some unique native species that co-occur with our invasive flora and fauna, and we’ll demonstrate how you can preserve or create their habitat while managing for invasive species and providing general tree care services.

Ornamental Plant Introductions: History and Consequences
Hallie Dozier, Ph.D., LSU AgCenter, School of Renewable Natural Resources

For centuries, we have introduced plants from other parts of the world to our landscapes. Today, some of the most valued introductions have turned the tables on us and pose ecological problems in our landscapes. What were we thinking? Take a look back on how we became a nation of plant enthusiasts and how our unbridled passion for plants has resulted in modern-day challenges. Hear some of the latest information about the spread, threat, and management efforts in Louisiana for cogon grass, Chinese privet, and others.

Pest Management/Crape Myrtle Bark Scale
Yan Chen, Ph.D., Hammond Research Center, LSU
Rodrigo Diaz, Ph.D., LSU Department of Entomology

Crape myrtle bark scale is a new, devastating exotic pest on crape myrtles, the most popular flowering shrub in the United States. This pest has spread to 11 states over the past 10 years. Newly reported infestation on native American beautyberry and pomegranate have raised concerns about its potential impact on the native plant community and other major crops. This presentation will cover the basic biology, distribution, and host range of this scale; discuss current control recommendations; and provide a peek into research directions and future management solutions.

Tree Decay Detection
Yadong Qi, Ph.D., Southern University
Malcolm Guidry, Ph.D., Consulting Arborist
Fred Fellner, Ph.D., LSU

Is your tree safe? This is a common question that gets asked a lot by both urban forestry professionals and customers. Hazard trees are those trees with structural defects that increase the chance of them failing and hitting a target. Tree defects are associated with many extrinsic and intrinsic contributors. In this field workshop we will inspect representative trees and conduct tree risk assessment using various techniques, including visual inspection and traditional and modern techniques such as resistograph and Picus Sonic Tomography. Demonstration of various techniques, prepared wood cores, and tree anatomy will be covered. You will gain some basic knowledge on the symptoms of tree damage, tree risk assessment, and tree decay detection devices.

Applying the Morphophysiological Approach to Tree Stability Assessment
Stefania Gasperini, AR.ES
Giovanni Morelli, Progetto Verde

In this session, conference presenters Stefania Gasperini and Giovanni Morelli will guide the observation of local trees from a “morphophysiological” point of view.

Break for Lunch

A boxed lunch will be provided for you to enjoy at City Park.

Audubon Park Tree Management
Daniel Illg, Audubon Nature Institute

Daniel Illg will discuss the efforts during his 15-year tenure to protect the historic live oaks and ensure that they are available for future generations of New Orleanians. With 20 years of experience as a horticulturist and arborist, Daniel oversees the tree care at all Audubon properties, with a focus on the trees in the Audubon Zoo and Audubon Park, prioritizing the long-term health of the trees.
