Native Wildflower Meadows: Let's Get Real
Larry Weaner
Principal, Larry Weaner Landscape Design Associates

Demand for native meadows, particularly as an alternative to lawn, is increasing, and yet few types of landscape plantings are more misunderstood than the native wildflower meadow, with many failures resulting from inadequate planning and the use of poorly adapted plants. Far better results can be obtained when the plants and processes used reflect the ecological character of our naturally occurring meadow communities. More than one-year wonders, meadows modeled on these ecosystems can provide long-term, easily managed landscapes that harbor a myriad of wildlife and provide color and texture throughout the year. In this all-day, in-depth workshop, Larry Weaner will discuss the design, implementation, and management of native meadows, using a series of case studies featuring large and small-scale meadows as well as projects ranging in age from initial establishment to over ten years in existence. He will also illustrate how garden design principles can be used in the meadow for subtle visual effect and to create graceful transitions to more formal garden areas. Larry Weaner has been creating native landscapes since 1977. He founded Larry Weaner Landscape Associates in 1982 and has gained a national reputation for combining ecological restoration with the traditions of garden design. This course carries 5.75 CEUs for ISA certified arborists (S=2, P=1.75, M=2) and 6 CEUs for PA landscape architects.

Single Rope Techniques
Rob Thigpen
Foreman, Shechtman Tree Care and ISA Penn-Del Chapter Climbing Champion
Rachel Brudzinski
Arborist, New York Botanical Garden, ISA Michigan Tree Climbing Female State Champion

Climbing techniques for arborists have advanced significantly in the last 20 years, with the adaptation of practices that were first developed by rock climbers and cave explorers. These techniques have made tree climbing easier and safer, and have
brought a greater degree of professionalism to arboriculture. The use of throw balls to advance the lead into the tree canopy has introduced the use of a single line as a means of ascension into a tree rather than the more traditional double line technique. The use of one line in climbing is known as Single Rope Technique (SRT), and has become a skill that has proved invaluable to many working arborists. This course will include some in-the-tree climbing, and is open only to arborists with field experience. Personal Protection Equipment (PPE) and individual climbing gear are mandatory. We will meet at Bloomfield Farm. Look for the paved road across Northwestern Avenue from the public garden entrance. Park in the lot and follow the signs to the Horticulture Center. This course carries 11.5 CEUs for ISA certified arborists (S=.75, P=10.75, M=0).

2016 Tree Canopy Conference
Haverford College, Stokes Hall Auditorium

Why is Tree Canopy so Important?
A healthy tree canopy provides important ecosystem services, including air pollution removal, storm
water runoff reduction, and building energy conservation. Abundant tree canopy provides habitat
for wildlife, and also has a positive impact on mental health and well-being, community cohesion,
and economic stimuli. At this conference, we will look at tree canopy preservation and reduction
both nationally and locally, and consider some of the greatest threats communities are facing as they
try to preserve tree canopy cover.

Featured Speakers include:

o Dr. Jay Townsend, who has done extensive research on the psychological impact of tree canopy
on city dwellers, will speak on trees as stress relievers;

o Dr. Jason Henning, Research Urban Forester, will highlight how to use I-Tree to manage tree

o Michele Adams, founder of Meliora Design, and Tavis Dockwiller of Viridian Landscape
Studio will discuss sustainable storm water management techniques; and

o Dr. William Powell, Professor and Director of the Council on Biotechnology in Forestry will
discuss his work to produce a blight resistant American chestnut.

Laura Hansplant
Director of Design, Roofmeadow

Louise Clarke
Horticulturist, Morris Arboretum

As the world population becomes more urbanized one of the challenges for landscape designers, architects, arborists, and horticulturists is to provide and maintain spaces for green infrastructure. The use of otherwise unused rooftops and walls to fulfill this need has become a popular alternative and a key component of environmentally friendly urban landscapes. Green roofs now provide many critical ecological functions such as cooling, water retention, and even food production. Join us for this day-long conference as we explore the green roof phenomena with three leading professionals in this emerging field.

Understanding Organic Approach to Soil & Plant Management
Chip Osborne
President of Osborne Organics

While many of us have seen the advantages and necessity of adopting an all-organic approach to the landscapes that we manage, it has not always been clear as to how to make the transition from traditional management with pesticides. In this orkshop Chip will offer a step-by-step process towards what he calls "The Systems Approach" to building better soil fertility that will in turn promote healthier growth of plants. In his practice Chip’s focus has been on turfgrass management, but the principles and techniques that he advocates are applicable for anyone that is interested in soil/plant interactions and the management of trees and shrubs in the landscapes that we maintain.

Trees and the Law
Rachel Roat
Attorney Specializing in Tree, Neighbor, and Garden Law

Rachel Roat is an attorney and master gardener who considers herself a "tree hugger." She will provide information on our rights and responsibilities in the garden, yard, and neighborhood. Rachel helps neighbors work out the tricky questions that arise when trees grow out of bounds, present hazards, block views, or are more loved by one party than by another. If a tree grows across the boundary between two properties, and now resides in two yards, it can give rise to many questions, including "Whose tree is it?", or "Who can cut it down or trim the branches?", "Who has to rake the leaves?", or "If it falls on my roof, who pays?" Rachel hates to see issues like this go to court, and her legal services include advice, negotiation, mediation, and then litigation, as a last resort.
