SUMMARY:Science and Solutions for a Clean Ocean
DESCRIPTION:Attend this virtual session to learn how to protect our lakes\, rivers\, and oceans with National Geographic Explorer Rachael Z. Miller!\n\n\nScience and solutions for a clean ocean\, lakes and rivers! \nIf you look for our trash\, derelict fishing gear and microplastic in any aquatic environment\, you will find it. This pollution is nearly ubiquitous and making its way through the marine and human food web – and onto our plates and into our bodies. National Geographic Explorer and Explorers Club Fellow Rachael Z. Miller is working to keep both macro and microplastic out of our public waterways. Rachael and her team at the ocean-protection nonprofit Rozalia Project for a Clean Ocean have been at the leading edge of marine debris and microplastic research\, data-driven cleanups\, solution development and solution implementation since 2010. They use a combination of expedition science\, innovation and education to make an impact from the surface to the seafloor in urban\, inland and coastal waters worldwide from the shores of Lake Champlain in their home state of Vermont\, down the length of the Hudson River\, remote islands in the Gulf of Maine\, the North Pole to Antarctica and thousands of miles in between. \nIn this presentation\, learn about Rozalia Project’s solutions-oriented programs\, Rachael and her team’s work in developing the Cora Ball\, a consumer-scale solution to microfiber pollution\, pioneering marine-debris-related educational programs\, widely cited scientific work and CSI for the Ocean\, a global citizen science microplastic mapping and monitoring program. She will leave you with actions everyone can take to protect our precious freshwater lakes and rivers and the one\, big ocean toward which they flow.

SUMMARY:Trees for a Changing Climate
DESCRIPTION:Join us for the annual Haverford College Arboretum\, Hardy Plant Society\, and Henry Botanic Garden Lecture\, presented by George Coombs.\n\n\nAs trees face increasing threats from climate change and novel pests and diseases\, it is essential to adapt our practices to protect and sustain our landscapes. Join the Mt. Cuba Center’s director of horticulture for an insightful discussion on strategies to safeguard their garden’s tree canopy. George Coombs will explain their strategic approach to choosing resilient species\, including the models and thought processes behind it\, their list of recommendations\, and the methods that will be used to track tree resilience over the coming decades. \n \nThis event is a partnership sponsored by Haverford College Arboretum\, the Hardy Plant Society\, and Henry Botanic Garden. At 2:00 p.m. there will be a free campus tour given by Haverford College Arboretum horticulturists. This lecture will take place in Sharpless Hall at Haverford College Arboretum and will be accompanied by light refreshments. \n \nSpeaker Biography: George Coombs is the director of horticulture at Mt. Cuba Center\, where he guides the care and development of one of the preeminent native plant gardens in America. To date\, his efforts have focused on making Mt. Cuba’s gardens more accessible to a growing number of guests and ensuring the long-term resilience of the garden. Prior to his current role\, George managed Mt. Cuba’s trial program\, publishing several research reports and helping bring new cultivars of native plants to market.

SUMMARY:Lost Forests
DESCRIPTION:Join Jonathan Wilson (Edward Drinker Cope Professor of Environmental Biology) to learn about the extinct plants of the high latitudes.\n\n\nLost Forests: Reconstructing the Extinct and Extreme Plants of the High Latitudes \nPolar environments present unique physical challenges for plants\, including endless nights in winter and continuous days in summer\, coupled with temperature\, wind\, and other stresses. However\, for the last three hundred million years\, there have been periods where trees and forests have grown at latitudes far beyond any tree on Earth today. How did they cope? In this talk\, I will discuss recent and ongoing research on fossil forests from near the poles—including Svalbard\, the Falkland Islands\, and Antarctica—and what they tell us about plant evolution and past environments. \n \nJonathan Paul Wilson is a paleobotanist and the Edward Drinker Cope Professor of Environmental Biology at Haverford College. He uses mathematical models to study the biophysical properties of extinct plants and employs these values in paleoclimatic and paleoecosystem simulations. For more information: Jonathan Wilson’s Biography. \n \nPhoto Caption: Growth rings in a cross-section of conifer wood (Protocedroxylon araucarioides) from Mesozoic Era strata in the Svalbard Archipelago \nParking for this event is in the Visitor’s Lot\, the talks location will be in Lutnick 200.

SUMMARY:Arbor Day Tree Planting

First observed at Haverford on April 4\, 1902\, representatives of the Pennsylvania Forestry Association came out to the campus to celebrate the holiday. It became such a popular celebration that in the early 1900s\, a song was arranged by J. H. Redfield\, Class of 1899\, and published by Hums and Noble. Over the years\, the Arboretum has planted hundreds of trees in honor of this special day. \nThis year\, our guest speaker will be our student workers. The location of the tree planting is behind VCAM. Members of Haverford College Arboretum will be able to take home their membership perk of a dividend plant during this event. Parking for off-campus community members can be found in the visitor parking lot.
