Workshop: Create a Terrarium with Native Plants

Have you ever seen a terrarium built from native evergreens?

Now’s your chance to make one for your own holiday table.

In this workshop learn how to make and cultivate a mini-ecosystem with native evergreen plants. Your terrarium will be an actual living mini-cultivating garden to be enjoyed throughout the winter and either planted outdoors in spring or kept to enjoy as a treasured indoor native plant terrarium. The native species being used in the project include ethically harvested native mosses, and partridgeberry plants cultivated from bare-root specifically for this workshop.

This workshop leaders, RIWPS members; Jennifer Fallon, Nathan Lamb, and Pat Cahalan, will cover the habitat, growing conditions and general characteristics that made some of our native plants, ferns and mosses, suitable for terrariums.  They will explain how to create a natural filtration system using charcoal as well as different materials and techniques. Additionally they will discuss container options including open vs. closed systems.

Location: University of Rhode Island Greenhouse

Limit 20 participants.  Registration required.  See below.

Workshop: Become a Citizen Scientist for the Bumblebees

Join Dr. Robert J. Gegear from UMASS Dartmouth for a workshop on what you can do to maximize biodiversity conservation in your own backyard by creating and sustaining pollination systems at risk of local extinction.

Dr. Gegear, who spoke at the Lisa Lofland Gould Lecture in the fall of 2019 about his research on the decline of bumblebees, and how citizen scientists can contribute to his Beecology Project, will lead this four-hour workshop on how to collect data on these species, take photos and/or videos of them, as they gather pollen from native plants, learn to identify them and note their behavior.

Participants will also learn how to assess the ecological value of pollinator and plant assemblages at different spatial scales, select native flowering plant species that maximize biodiversity, and hone their skills for contributing to the Beecology citizen science project.

The workshop will be in the meadow of long-time RIWPS member, Susan Marcus. Bring your lunch. We will provide iced tea, lemonade and water.

Rain Date. September 26, 2021 at the same time, 10 am to 2 pm.
