That is a part of a sequence with Excellent Earth Undertaking, a nonprofit devoted to toxic-free, nature-based gardening, on how one can be extra sustainable in your landscapes at dwelling.
“Now we have declared 2024 the 12 months of milkweed,” says Andi Pettis, director of horticulture at Governors Island. For the previous couple of years, Pettis and her staff have been busy incorporating milkweed into the island’s plantings. They’re specializing in the three species native to the ecoregion: butterfly weed (Pettis’s favourite due to the “unbelievable variation in colour from golden yellow to nearly scarlet”), mauvy widespread milkweed, and sizzling pink swamp milkweed. Her objective is to complete planting 5,000 milkweed vegetation this 12 months. “Displaying the connection between monarch butterflies and milkweed is a straightforward means for us to attach folks to the advantages of native vegetation and present them why it’s vital to help wildlife even in an city atmosphere.” The efforts have paid off. They’ve been noticing increasingly monarchs on the island. You’ve heard it earlier than: In the event you plant it, they actually do come. (See Monarch Butterflies Are Nearing Extinction: 5 Methods to Assist.)
Planting milkweed is simply one of many many initiatives that Pettis and her staff are doing to bolster biodiversity. “Local weather resiliency and sustainability had been type of baked into the design of the park,” she says. Created by the design agency West 8, with Mathews Nielson Panorama Architects, the park options 120 acres of hills, meadows, and forests in the midst of New York Harbor. “It was a reuse undertaking actually—an previous navy base became a public area with new parks,” she stated. “However there was no horticulture employees once I was employed [six years ago].” Pettis, who skilled at Brooklyn Botanic Backyard and had risen by the ranks at The Excessive Line to turn into director of horticulture earlier than shifting to Governors Island, needed to construct a staff from scratch and started to rehabilitate areas the place upkeep had been deferred for years. At the moment, she and her staff have launched 52 native plant species to the island, planted habitat for butterflies and birds, and introduced in sheep to tame the rampant unfold of invasive species. “We’re working with nature right here,” she says. “It’s not a brief repair, nevertheless it’s working. We’re on this for the lengthy haul.”

Q: How are you gardening for biodiversity?
A: The park was designed for sustainability and local weather resilience. West 8 constructed hills and these sorts of swales and berms to lift a part of the park out of the 100-year floodplain. Working with Matthews Nielsen, they created a variety of naturalistic areas based mostly on coastal maritime plant communities and crammed the park with a variety of native timber. I feel there are 53 completely different species of native timber planted on the South Island alone!
Now we have made it clear that we’re selecting vegetation that mimic our coastal maritime shrublands and grasslands native plant communities. We’re additionally specializing in people who profit biodiversity and wildlife. In areas the place we now have managed to retake the land with these native plant communities, we’ve seen enormous upticks within the native insect populations.
Q: How are you adapting to our altering local weather?

A: As temperatures heat, we’re undoubtedly experimenting with vegetation that may be thought-about extra Southern. For instance, we’re contemplating planting reside oaks on the island. We’re additionally rising pawpaws, persimmons, and magnolias which can be all doing actually very properly.
