Native Bee Species Ebb and Flow with Native Plants Bloom: A Year’s Calendar with Sam Droege, watch webinar

/2 Comments/in , /by

Zoom Video Conference
Held Thursday, 14 May 2020
Watch recorded presentation

All of our nearly 500 species of native bees are dependent on pollen to feed their young. No flowers, no bees. Like flowers, each bee species has its season. During a bee’s flight time they are often dependent on the pollen from only a small group of plants, ignoring the rest.

What you plant has consequences for the bees you support on your property. Travel through a year in the region, tracking the flowers and their bees, or…the bees and their flowers (depending on your point of view!)

Sam Droege has been spent most of his career at the USGS Patuxent Wildlife Research Center. He has coordinated the North American Breeding Bird Survey Program, developed the North American Amphibian Monitoring Program, the BioBlitz, Cricket Crawl, and FrogwatchUSA programs and worked on the design and evaluation of monitoring programs. Currently he is developing an inventory and monitoring program for native bees, online identification guides for North American bees at www.discoverlife.org, and with Jessica Zelt reviving the North American Bird Phenology Program.

7:30 – 9 pm

Nature is intricately interconnected. While we certainly don’t know how all the pieces fit, we can have some informative fun trying to put them together. Virginia Native Plant Society, Potowmack Chapter presents an interesting look at how pieces of the “nature puzzle” fit together, focusing on our native flora and wildlife of course. Get a peek at just how interdependent are plants, fungi, insects, wildlife, and even humans can be and try to piece together some parts of our local nature puzzle. Take a look at host plants, oligolectic bees, ethnobotany, and other wildlife interactions. You may not look at our natural world the same way again. 

Alonso Abugattas is a well-known local naturalist, environmental educator, and storyteller in the Washington, DC area. He is the Natural Resources Manager for Arlington County Parks, VA and the longtime Co-Chair for the Beltway Chapter of Region 2 of the National Association for Interpretation, the professional association for naturalists, historians, and docents. He was awarded their Regional Outstanding Interpretive Manager Award in 2018 and the national Master Interpretive Manager in 2018. He has been trained as a Master Gardener, was made an honorary Virginia Master Naturalist for his role in starting 2 chapters, and serves as an instructor for both.

Earth’s Climate: Present, Past, and Future, VNPS Annual Workshop, Mar. 14th

Piedmont Virginia Community College
V. Earl Dickinson Building Theater, 444 College Dr., Charlottesville VA
Saturday, 14 March 2020
9 am – 3:15 pm

Many are concerned about climate change and no longer need to be convinced that it is real. But we can always learn something new about the study of climate and its changes and impacts on Earth’s ecosystems. This Workshop will focus on climate changes at different periods of time, how it might relate to our current climate, and inform our thoughts about today’s changes.

The speakers this year will cover more than 50 million years of Earth’s climate history. From the present state of our coastal ecosystems, to climate perturbations during the historic period, to the glacial ages and their influence on eastern forests, and finally to the fossil record far in the past, we will explore environmental changes in our world.

For example, every fall and spring, Mason students assist National Park Service Staff at Shenandoah National Park to remove invasive plants along the Appalachian Trail. In addition, Mason students are leaders in urban agriculture through traditional gardening (raised beds) and alternative gardening (hydroponics, FarmBot) methods. The presenter will share information about a potential new learning opportunity for students – a citizen science experience in Puerto Rico.

Dr. Peter Mecca has a Ph.D. in Curriculum and Instruction and Ecology from Pennsylvania State University, an M.A. degree in Environmental Biology from Hood College, and a B.S. degree in Secondary Education – Biology from Penn State.

Plants of the Forest Floor, A Talk by Margaret Chatham, Oct. 10th

7:30 pm

Everyone knows that plants use the energy of sunlight to grow and feed the rest of the world. So how do plants live on the dark forest floor? Margaret Chatham will discuss a number of the strategies plants use to survive in the (relative) dark, with special attention to the mycorrhizal associations scientists are still in the process of unravelling.

Margaret is a devoted Fraser Preserve Volunteer Visitation Committee Member who removes invasive barberry shrubs in winter and wavyleaf grass in summer and knows the preserve intimately. She is also editor of the VNPS Potowmack News newsletter, a volunteer at the VNPS propagation beds at Green Spring Gardens in Alexandria, and an Arlington Regional Master Naturalist.

Butterflies and Blossoms, or Larval Host Plants and the Lepidoptera that Eat Them
Thursday, February 14, 7:30 pm – 9:00 pm
Green Spring Gardens, 4603 Green Spring Road, Alexandria VA

No reservations are necessary for this talk.
Virginia Native Plant Society programs are free and open to the public.

Margaret Chatham will discuss butterflies, caterpillars, and larval host plants.

Beautiful butterflies and lovely blossoms are all the result of trying to make a living. The plants need someone to pollinate them, but at the same time need to limit the number of caterpillars and other insects that can eat them. The butterflies and caterpillars need to avoid being eaten long enough to lay eggs for the next generation. Learn which natives to plant to nurture more than just monarchs.

2010 was a good year for butterfly photographs in our area. Margaret Chatham took a lot of pictures that year. Then she wanted to know who they were and what they ate. No year since has offered her quite as many butterflies, but every season brings something new, so now she wants to share them.

Margaret is a devoted Fraser Preserve Volunteer Visitation Committee Member who removes invasive barberry shrubs in winter and wavyleaf grass in summer and knows the preserve intimately. She is also editor of the VNPS Potowmack News newsletter, a volunteer at the VNPS propagation beds at Green Spring Gardens in Alexandria, and an Arlington Regional Master Naturalist.
