Quick Summary

The Bronx Zoo has planted twenty hybrid American Chestnut saplings as part of a city-wide initiative to revive the species ravaged by a deadly fungus since 1904. Craig Piper, interim director of the Bronx Zoo, and Jason Smith from the New York Restoration Project highlight the historic significance of reintroducing chestnuts after a century-long absence. The hybrid trees are resilient against the blight but may still be affected, serving as both research specimens and educational exhibits for zoo visitors.

Story summary

The Wildlife Conservation Society’s Bronx Zoo, in partnership with the New York Restoration Project (NYRP) and The American Chestnut Foundation, planted 25 hybrid American chestnut saplings on October 5th. This marks a significant restoration effort for a species once abundant but now considered "functionally extinct" due to a deadly blight that began its spread in the Bronx Zoo over 120 years ago. The original American chestnut was one of the largest and most vital trees in eastern US forests, with nearly 4 billion being killed by the fungus since its discovery. These new saplings are hybrids designed to be more resistant to the blight, though they may still contract it as they grow.

🔮 A highly contentious New York State race under watch by the entire nation has been plunged into chaos over voting ballot “thickness” — an issue that could mean the winner won’t be known for days.
🔮 “NYC DOT has recently installed two all-way stop signs around this school in response to community requests— these decisions are guided by safety data and unique local conditions, and we will always work with communities to make our streets safer for everyone.”
🔮 Construction crews first wrecked the owls’ nest while dismantling a water tower on the Upper West Side building earlier this week, and DEC police ordered demolition to stop so the agency could investigate potential violations.
🔮 Anthony Daniel Palazzolo, 42, allegedly sent a series of Facebook messages to Patel’s associate earlier this month claiming he would target the bureau and had “put a hit out” on the director, according to United States Attorney Jerome F. Gorgon, Jr. In one phone call, Palazzolo, of Chesterfield Township, allegedly told an FBI agent he would show up to the Detroit field office and “use deadly force against every single one of you government officials—FBI Secret Service will all be f[——] killed,” investigators said.
🔮 “My biggest thing was you could be the best driver on this planet, but other people just don’t know how to drive.”
🔮 Renzi witnessed as many as 400 bikes “blocking sidewalks and causing mayhem” at any given time, she said — with deliveristas treating the corner as a waiting room between Uber Eats and Seamless orders.
🔮 A lot of mental was really what it would be, but I do think it’s mainly based on the actual mile rather than exactly where it is.” What pulled Medjid through was seeing his friends and fellow running community members along the route — which helped him remember why he was running the race. “Before the race, write it on your hand.
🔮 The heavy patrol will include helicopters, drones, thousands of police barricades and more along the 26.2-mile route — which officials lined with colorful strips of paint Wednesday.
🔮 The local real estate broker admits that this year’s pumpkin is roughly 100 pounds lighter than last year’s — theorizing that the summer’s heavy rain may have been to blame for the stunted gourds. But he’s made up for the slight dip in size by planting several other pumpkins — ranging from 2 pounds to 120 pounds — and bales of hay across his 8th Avenue property.
🔮 A Paralympian and world-record holder will make history this weekend when she becomes the first blind solo cyclist to complete the annual 100-mile Century Ride race around the Big Apple.

Narrative

Hermann Merkel was the first to document the blight in 1904 — writing that “unless some radical measures are taken, or a natural enemy of this fungus develops, it is safe to predict that not a live specimen of the American Chestnut will be found two years hence in the neighborhood of the Zoological Park,” the former name of the Bronx Zoo. The blight would go on to decimate nearly 4 billion American chestnut trees across North America, rendering it “functionally extinct.” But the 20 saplings aren’t exactly the same trees whose canopy once blanketed the US — the 3-foot-tall trees planted Monday are a hybrid mix that horticulturalists hope will make them stronger against the blight they expect to eventually creep onto the trees. “These trees most likely will get the disease, and it will impact them.

We haven’t had chestnuts on property here for a hundred years,” Craig Piper, the interim director of the Bronx Zoo, told The Post as he watched his team tenderly plant the tiny trees. asserted

The zoo’s mini forest, erected in conjunction with the New York Restoration Project (NYRP), marks the first time American Chestnuts have been on the zoo’s property since its former Chief Forester discovered a “deadly fungus” was eating away at the gorgeous, 100-foot-tall trees. asserted

we also expect them to grow,” said Jason Smith, the NYRP’s Director, Northern Manhattan Parks, saying that the “worst-case scenario” would be that the trees wouldn’t flower and reproduce. asserted

The trees will also serve as a research opportunity — they will be under constant observation by the zoo’s horticulture staff to see how the saplings are faring. Seventeen were planted across two plots along the Bronx River in order to receive maximum sunlight and less traffic, while three live in the shadier footpath north of Tiger Mountain where they are essentially on exhibit like their neighboring felines — visitors will get a first-hand look at their growth and zoologists will point out their story as they take families through the park. asserted

“We’re inviting New Yorkers to engage in hands-on, important work to address the biodiversity crisis by bringing back a tree that was on the brink of extinction,” said Smith. asserted

Just around 400 American Chestnut trees exist in the five boroughs, nearly all of which were planted by the NYRP with the help of the American Chestnut Foundation. asserted
