Light breakfast & lunch are included both days.

Landscape at Hand Scale (1 hour 15 min.)
Mathieu Gontier & François Vadepied

From studio to site, from observation to realization, and from planting to maintaining, Mathieu and François will emphasize the gardener attitude that is part and parcel of their projects. Moving from plants to materials, they will discuss where the sensible line falls between emission-heavy construction and a material-reuse approach. Overall they will demonstrate how we can change our engagement with landscape, program, transformation, and maintenance to help create tomorrow’s cities that give hope for a resilient future.

Floristic Assessment of Natural Landscapes (1 hour 15 min.)
Gerould Wilhelm, Ph.D.

Gerould Wilhelm is one of North America’s most accomplished botanists. He invented the landscape assessment tool, Floristic Quality Assessment, which provides landscape practitioners with an objective-oriented decision tree that can inform potential habitat modifications, future management adjustments, and an ability to monitor those impacts. Initially presented in the 1970s, this tool has since been developed for most regions in North America and several in Europe. Attendees will discover the fundamental ecological realities that govern our culture’s relationship with landscapes around us, and discover that an analysis of existing plant arrays in specific landscape contexts can guide a rational plan for landscape restoration and stewardship.

Remnant Prairies and Grassland Restoration in the Mid-Atlantic Piedmont (1 hour 10 min.)
Bert Harris, Ph.D.

Harris will begin by covering the Clifton Institute’s recent research which found that remnant Piedmont prairies are the most diverse plant communities in Virginia; even more diverse than Midwestern tallgrass prairies. He’ll then talk about the Institute’s 100-acre grassland restoration experiment that is testing eight different methods (e.g. fire, tilling, planting, herbicide) to convert non-native fields to native meadows. He’ll finish by discussing the Virginia Native Seed Project that has the goal of making seeds with local genetics available commercially for meadow plantings and roadside revegetation projects.

Informed Plant Selection to Support Pollinator and Songbird Conservation (1 hour 10 min.)
Desiree Narango, Ph.D.

The choice of plant species in landscaping and restoration plays a vital role in creating habitats where pollinators and other wildlife can thrive. In this talk, Dr. Desiree L. Narango will share insights from her research, past and present, exploring which plant species and traits are most effective in supporting pollinating insects and songbirds. In addition, information will include little-discussed but highly relevant aspects of habitat creation including multi-trophic plant-wildlife interactions, and habitat relationships of wildlife with specialized life histories. Finally, she will connect theory and application by revealing practical decision-support tools for making ecologically sound plant choices.

Shrouded in Light: Plantings Inspired by Wild Shrublands (1 hour 10 min.)
Michael Guidi & Kevin Philip Williams

Shrub-dominated plant communities exist all around us. Unlike meadows and woodlands however, they are rarely included in designed landscapes as a distinct community type. Beyond their inherent beauty these ecosystems provide crucial wildlife habitat, resilience in the face of a changing climate, and visual legibility for visitors through their distinct distribution patterns. Join the authors of Shrouded in Light: Naturalistic Planting Inspired by Wild Shrublands (Filbert Press US 2024) as they explore the ecological significance, design strategies, and practical planting approaches to this crucial - yet often neglected - ecosystem component.
