Native Green Roofs: Natural Applications for Artificial Conditions | Ethan Dropkin & Laura Hansplant
By drawing inspiration from plant communities with similar conditions, we can create green roofs that are ecologically complex, highly resilient, and provide significant ecological benefits. Maintenance requirements, typically high on traditional roof gardens, can also be reduced. This session will use case studies to illustrate ecological, horticultural, and engineering techniques for designing green roofs as high-performing elevated habitat.

Mar 06 to Mar 06
Most insects have a positive impact in our landscapes. Native plants can be selected to attract specific bees and beneficial insects including predatory and parasitic wasps, beetles, flies, true bugs, and lacewings. Learn about the predator-prey relationships of these flower-visiting beneficial insects and how they help keep problem insect populations in balance. The life cycles, diversity, and nesting habitat of native bees will also be covered along with examples of native plants for different site conditions. Presenter Heather Holm is a biologist, pollinator conservationist, and AHS award-winning author. In addition to assisting with native bee research projects, she informs and educates audiences nationwide, through her writing and many presentations, about the fascinating world of native pollinators and beneficial insects, and the native plant communities that support them. This is a joint venture with the Audubon Society of Northern Virginia.

Planting and Managing Ecology-Based Landscapes: Specification, Implementation, & Monitoring | Rebecca Kagle, Andrew Korzon, & Scott Woodbury
Part One | Specifications for Restoration-Scale Projects - Rebecca Kagle, Andrew Korzon Many ecology-based field techniques run counter to traditional practices and are unfamiliar to even highly experienced contractors. Consequently, highly precise specifications are crucial. This presentation will cover the documentation of field procedures unique to ecological design and restoration such as phased planting, meadow seeding, and weed control procedures. We will also discuss organizational formats for specifications that distinguish between short-term and longterm management and balance the need for both detail and usability. Part Two | Reconstructing Tallgrass Prairie in Urban and Suburban Spaces: Two Case Studies - Scott Woodbury Tallgrass prairie reconstruction from seed on damaged urban and suburban soil is a practice poorly understood by most landscape personnel. A seeding specification can lay out a blueprint for planning, site preparation, installation and maintenance, but it is dependent on an engaged and informed team of people, from leaders to weeders. Seeded landscapes are so complex that simple mistakes can be made that result in significant setbacks or failure. This session will focus on how to plan, implement, and manage successful commercial seeded projects. Wednesday, March 10th, 2021 | 1:00 - 4:30 PM EST
