Session Titles/Descriptions

Resilient coastal landscape design: a multi-pronged approach to heal, protect, and enhance shoreline ecosystems
Tara Mahon Vincenta, PLA, FASLA Artemis Landscape Architects

Tara will discuss her unique approach to combining considerations of site, local ecosystems, regulations, and client goals to facilitate resilient coastal residential design. Tara is nationally recognized for her thoughtful, beautifully detailed work that harmonizes environmental sustainability and healing while fostering personal connections for all who encounter her designed spaces. In this talk, Tara will highlight three distinct projects and her approach to creative problem solving for (1) a tidal marshland, (2) constructed dunes on a Long Island Sound beachfront, and (3) inland wetland and coastal buffers at a RI oceanfront property. 

Climate Forward Tree Care
Christopher Roddick, Sweet Birch Land & Tree

Because trees are rooted in and can’t run away, they must adapt to anything that comes their way. Storms, pests, disease, even development - trees are in a constant state of reacting to the environment around them. Can we help? This talk will look at ways trees adapt to protect themselves and the associate organisms that live with and among them. We’ll discuss what strategies to use and practices to change to help trees as well as the flora, fauna, and funga that rely on them.

Brave New World for a Coastal Forest
Juliana Barrett, University of 51³Ô¹ÏºÚÁÏecticut Sea Grant College Program

Using the case study of a project to develop a resilient coastal forest on an Avalonia Land Conservancy property in Stonington, CT, Juliana will explore the factors for selecting the right plant for the right place at the right time given our current and future environmental changes.

Rain, Rain, Go Away: Reducing Runoff One Garden at a Time
Nicole Davis, Save the Sound

Rethinking how stormwater can be used as a resource to enhance the landscape and create habitat. Like so many things we do at home— small actions can have lasting impacts, especially as more people start to adopt them. Rain gardens are a simple low maintenance garden, that can easily be used to manage stormwater runoff, and can help to reduce localized flooding, recharge groundwater, reduce the burden on public infrastructure, and reduce pollution reaching our waterways.

Panel Discussion
Tara Mahon Vincenta, Christopher Roddick, Juliana Barrett, Nicole Davis

Panel discussion responding to registrant-submitted questions about specific sites and situations.
