What a difference 100 years makes. Recently, the GTA team visited the Middle Branch Park living shoreline project. Today, the newly installed living shoreline is flourishing with native plants and newly arriving critters. 100 years ago, the Harbor Hospital property and shoreline was occupied by Maryland Yacht Club (from 1908 - 1955). What an improvement over a long-time dilapidated shoreline!

As an Accredited Land Trust, GTA has been busy wrapping up our annual conservation easement monitoring. Our protected sites stretch from bald cypress swamps in coastal North Carolina, through Virginia’s Shenandoah Valley and the coastal plains of Maryland and New Jersey, and as far north as Massachusetts.
It is always rewarding to revisit these properties, see restored ecosystems continue to mature, and experience the forests, wetlands, streams, and other natural areas protected in perpetuity through conservation easements.

Thank you to Chesapeake Employers Insurance and Broadmead for a fun day supporting our ecosystem by removing invasive plants species!

Chesapeake Employers Insurance generously donated their time and labor to support the environmental efforts of Broadmead. Broadmead is doing all they can to create a thriving ecosystem at their property through adding native plant species while also removing/cutting back invasive plants.

We are thrilled to partner with groups like these!

GTA and nearly a dozen other partners including ServPro of York-Lancaster, Sylva Natives Nursery, and Pikesville Lumber, supported an ambitious Eagle Scout project to build an outdoor classroom with native plantings at Loyola HS in Towson. What a project!

Each of GTA's staff members are deeply involved in local conservation mentoring through scouting, master gardener programs and master naturalist programs. Each summer, executive director Kirk Mantay teaches a week-long fish and Wildlife management course for Baltimore City scouts, held on Maryland's eastern shore.

Taking a critical look at 27 acres of wetlands restored by GTA, MDE, the Chesapeake Bay Trust , GreenVest, LLC and Environmental Quality Resources in 2016. The habitat management continues, but it's headed in the right direction!

What a great way to wrap up the school year!

Green Trust Alliance staff had an incredible time partnering with St. Mark School Catonsville as 50 enthusiastic 6th grade students dug in to help install a new pollinator garden on campus.

This hands-in-the-dirt project gave students the opportunity to learn about human impacts on the environment while taking direct action to support local pollinators and improve habitat right in their own community. The project also supports St. Mark’s Maryland Green School Certification.

Best of all, every student had the chance to plant a flower and leave their mark on a project that will continue to grow for years to come.

Thank you to the students and staff at St. Mark School for making this such a fun and meaningful day of environmental stewardship!
