– Under the K Bridge Park (Meeker Ave and Van Dam Street): a unique 7-acre park under the BQE, where you’ll tend to the native plant nursery, our ecological lab for cultivating biodiversity amongst heavy industry.
– McGolrick Park (Nassau Ave between Russell and Monitor Streets): an Olmsted-era neighborhood park with a stunning mature tree canopy.
You’ll work with our horticultural experts to learn about the ecological needs of each space: weeding invasive plant species, propagating and transplanting native plants, amending soil, and caring for trees.
