BURLINGTON (AP) -- Hubert "Hub" Vogelmann, the University of Vermont scientist who helped document air pollution damage to trees on one of the state’s most famous mountains, has died.

Vogelmann, 84, died Friday at Respite House in Williston. No cause of death was released.

"We are saddened to report the passing of Hub Vogelmann. We’re grateful for all the support we are receiving from Hub’s many friends and colleagues," Vogelmann’s family said in a statement released by the university.

A native of Buffalo, N.Y., Vogelmann received a PhD in botany from the University of Michigan. He worked at UVM from 1955 through 1991.

Vogelmann was perhaps best known for his November 1982 article in "Natural History" called "Catastrophe on Camels Hump," which traced the decline of an uplands habitat on the mountain now featured on the Vermont quarter, the Burlington Free Press reports.

Vogelmann’s long-term study of high-elevation ecosystems in the Green Mountains, begun in 1963, informed his determination that fossil-fuel emissions had significantly altered the ecosystem’s soil chemistry. In less than two decades biomass production at Camels Hump’s higher reaches declined by 41 percent.

"He had hard data about a real thing, a real place that we all cared about -- he wasn’t just describing someone else’s work," said Bob Klein, the first Vermont director of The Nature Conservancy who worked for Vogelmann for decades.
