Join us Thursday, September 18, 2025 from 5-7pm at Octoraro Native Plant Nursery for an evening to network with your friends and colleagues in the ecological landscaping field.
Octoraro Native Plant Nursery has been supplying seed grown native trees and shrubs to the Mid-Atlantic region for 35 years. Traditionally specializing in wetland trees and shrubs, millions of plants grown at the nursery have been planted in riparian buffers, reforestation projects, large landscape designs, and more. Currently, ownership is transitioning from Jim MacKenzie and Mark Gutshall to Kevin and Claire Zuidervliet. This transition promises to honor Octoraro’s strong legacy as a high-quality grower, while also cultivating new relationships and exploring more native plant species to be added to our offerings.
Please join us for an evening of food and tours at Octoraro Native Plant Nursery’s propagation facility. Tours will focus on how Octoraro sustainably grows native trees and shrubs for restoration efforts, landscape contractors, and retail businesses. There will also be discussions and examples of underutilized native species that Octoraro is developing propagation and growing protocols to better serve the growing demand for native plants.

2025 Chesapeake Watershed Forum
2025-11-07 08:00 - 2025-11-09 17:00 | National Conservation Training Center, 698 Conservation Way, Shepherdstown, WV, 25443, United States
Kevin Zuidervliet of Octoraro Native Plant Nursery will be presenting!
For two decades, the Chesapeake Watershed Forum has brought together partners to collaborate, innovate, and drive meaningful progress in restoring and protecting the shared waters of the Chesapeake Bay watershed. As we mark this milestone 20th anniversary, we have an opportunity to reflect on the successes and challenges that have shaped our work and the lessons that will guide us forward.
2025 is a pivotal year – both a moment to celebrate how far we have come and a chance to plan for what’s ahead. Planning for 2025 and Beyond efforts led by the Chesapeake Bay Program challenge us to think critically about the future of conservation and restoration efforts. While uncertainties exist, by embracing a mindset of resilience and adaptability, we can continue building a strong foundation for the next generation of conservationists in our region.
This year’s theme centers on human-centered approaches – ensuring that the needs, well-being, and aspirations of people remain at the core of our work. By prioritizing trust and collaborative decision-making, we create impactful solutions and longstanding outcomes. Our ability to navigate change isn’t just about responding to external forces; it’s about proactively shaping a future that meets the needs and collective futures for all of us.
