Dr. Linda Rohleder recently ended a position as Director of Land Stewardship at the New York – New Jersey Trail Conference where she built the Trail Conference’s Invasives Strike Force volunteer program starting in 2011. By 2021, the program had trained over 400 invasives-mapping volunteers who collectively surveyed more than 1,500 miles of hiking trails for invasive plants. She organized more than 100 invasives-removal workdays and ran a seasonal conservation corps crew for seven years to remove invasive plants in parks across southern New York and northern New Jersey. Dr. Rohleder was also the founding coordinator of the Lower Hudson Partnership for Regional Invasive Species Management (PRISM) in New York leading it for almost ten years. She grew the partnership to over 50 organizations and agencies, and led the development and implementation of regional strategy for invasive species management in the Lower Hudson. In addition, Dr. Rohleder led a volunteer group to create and maintain the Trail Conference’s native plant gardens from 2016 through 2021 and conduct restoration projects at sites on New York and New Jersey state park lands.

In 2013, Dr. Rohleder received her PhD in Ecology from Rutgers University, where she studied the effects of deer on forest understories. While attending graduate school she worked as a seasonal park resource assistant in Monmouth County, NJ, and taught beginning Biology labs at Rutgers and Wetland Plant ID for Rutgers’ Wetland Delineation certification series. Dr. Rohleder has also spent more than 20 years creating native plant wildlife habitat on her own properties both in New Jersey and New York.

Rich is a retired Landscape Architect. He received his degree in Landscape Architecture from Rutgers University. He began his professional career at a civil engineering firm where he gained significant knowledge of site planning, environmental assessment, and site feasibility analysis for a variety of land use projects.

In the middle of his landscape design career, he took a different route for a while. He became interested in native plants during the early years of the movement. He established Wild Earth Native Plant Nursery in Jackson, NJ and ran it for approximately thirteen years. During this time, he learned from experience how to germinate and grow over 300 species of native plants – wildflowers, ferns, grasses, shrubs and trees. His customers included homeowners, regional parks and preserves and environmental restoration projects.

After closing his nursery, Rich worked for more than a dozen years in the design department of Monmouth County Park System in New Jersey as the Chief Landscape Architect. He co-led several volunteer work days for the New York – New Jersey Trail Conference to lay out and install native plantings at the Trail Conference’s headquarters and state parks restoration sites.

Rich continues to periodically conduct various consultations with clients regarding landscape design, natural restoration, environmental quality assessment and natural playgrounds. In his spare time, Rich enjoys making rustic garden structures, and dabbling in archaeology, genealogy, and geology.
