Evolution of the American Landscape: Gardening in a Changing Climate

Bayard Cutting Arboretum

February 25, 2019 , 8:00 AM–5:00 PM

8:00 AM - Registration and Refreshments

8:30 AM - Welcoming remarks by Doreen M. Monteleone, Past President of the Bayard Cutting Arboretum Horticultural Society and Nelson Sterner, Director, Bayard Cutting Arboretum

8:45 AM - What a Warming World Means for Pest Outbreaks

Michael Raupp, PH.D., Professor Dept. of Entomology University of Maryland will review evidence for climate change and explore possible causes. He will show how warmer temperatures can alter ranges of pests, seasonal phenology of insects and mites, and interactions among plants, herbivores, and their natural enemies. Special emphasis will be placed on invasive species and urban heat islands.

9:45 AM - The Climate Change Garden

Johathan Lehrer, PH.D., Chair, Urban Horticulture & Design, Farmingdale State College will be talking about the plant palette employed by horticulturists in the NYC metropolitan area has changed dramatically in the last 50 years with many losses and additions. These changes may be attributed to many factors including advances in plant breeding and the advent of new diseases and insect pests. It is a global climate change, however, that serves as an underlying force driving many of the changes we observe i our local flora. Join Dr. Lehrer as he outlines these phenomena and gives specific examples of local challenges and opportunities.

10:45 AM Refreshment Break Upper Carriage House

11:15 AM - Innovating the Urban Environment through Green Roof Implementation

Max Lerner, Sustainable Project Development Coordinator, NYC Department of Parks and Recreation will be speaking about the largest holder of natural assets in New York City, the New York City Department of Parks and Recreation manages 14 percent of the five-borough area. NYC Parks’ mission is to create resilient and sustainable public spaces for both present and future generations. To further the goal, his team is coordination the “Million Sq. Ft. Green Roof Project” to construct 1,000,000 sq ft of rooftop green infrastructure on 100 of their facilities. This work holds an incredible potential to directly and indirectly improve our city by sequestering up to 1” of rainwater per sq. ft., create ongoing carbon sequestration, pollutant control, combined sewer overflow(CSO) prevention, biodiversity accommodation and overall public education around urban green spaces. Through this project, NYC Parks will advance its existing green infrastructure efforts to help solve critical urban environmental issues impacting the New York City and beyond.

12:15 PM - Lunch Break

1:30 PM - From Western wilderness to Backyard Gardens: How ecology can Improve our Managed Landscapes

Jill Gail, Horticulturist & Field Ecologist, formerly with Rocky Mountain Biological Laboratory talks about whether studying the subalpine flora of Colorado, combing through tall grass prairie in the Midwest, identifying native pollinators in California, or tending public gardens in New York, both the ecological sciences and horticulture are deeply intertwined. This talk explores that connection and how we, as gardeners, can utilize both fields to create more beautiful and resilient landscapes that adapt to our dynamic environment.

2:30 PM - Refreshment Break Upper Carriage House

3:00 PM - Horticultural Practices for a Changing World: Sustainable Gardening at Bayard Cutting Arboretum

Kevin Wiecks, Landscape Curator, Bayard Cutting Arboretum will speak on his observations and adaptations to the environmental challenges he has faced during his career in public horticulture - from growing fruit in the Negev Desert in Israel to restoring a three-quarter of a mile perennial borden on the Harlem river after Hurricane Sandy. Most importantly, he will discuss the projects and horticultural practives at Bayard Cutting Arboretum that are being adopted in response to the stresses of climate change.

4:00 PM- Nelson Sterner, Director, Bayard Cutting Arboretum closing statement.
