LECTURES ARE HELD FROM 6:30 TO 7:30 PM
- Monday, January 27, 2014 - History and Definitions
Why do we have separate lawns and flowerbeds? Plants can be native, naturalized, alien, exotic, invasive, and so on - what does it all mean? What’s the difference between wildflowers and weeds? What do we mean by “wilderness” anyway? We’ll discuss overlapping ideas such as ecological landscaping, garden habitats, native gardening, sustainable landscaping, and restoration in this first session.
- Monday, February 3, 2014 - History and Definitions; Biodiversity
We will continue to explore different approaches to gardening and landscaping, including a discussion of biodiversity, especially as it relates to urban and suburban settings.
- Monday, February 10, 2014 - Changing Lawn and Garden Practices
Starting with the easiest approaches first, we will discuss simple modifications to conventional lawn and garden practices that can promote biodiversity and sustainability.
- Monday, February 17, 2014 - Creating a Wild Landscape
This class will look at how to create a wild landscape from the beginning. We’ll discuss the application of ideas from restoration ecology and related fields that can be used to create and manage a wilder landscape on the scale of a typical homeowner’s yard.
- Monday, February 24, 2014 - Changing Lawns to Meadows and Flowerbeds to Woodlands
This week we’ll use ideas from restoration ecology and related fields to consider more gradual approaches to modifying highly groomed landscapes.
- No class Monday, March 3 for the Philadelphia Flower Show.
- Monday, March 10, 2014 - Managing a Wild Landscape
This class will look at ways to gain control of neglected land that don’t involve starting all over.
The idea of a wilder yard isn’t new, but there is a resurgence of interest in gardens that resemble natural habitats instead of rows of crops. This course will start by looking at why we have the kinds of lawns and gardens we do, and then consider alternatives. While there will be practical information about plants that could be used for a more naturally sustainable landscape, the focus of the course will be on helping students assemble the knowledge and resources to manage their own yards and gardens.
A course website will include lists of resources and presentation notes.
