Araucarilândia: Ecology, Culture, and Conservation of Araucaria angustifolia The primary goal of my recent trip to trip to southern Brazil was to go to the places John Muir visited in 1911 on his quest to see Araucaria angustifolia, one of the species of the ancient conifer family with which he was fascinated, and to see for myself what had changed compared with the …...

A Visit to the Big Tree We had spent the morning with Dr. Rafael Barbizan Sühs, a landscape ecologist working at the Federal University of Santa Catarina in Florianópolis. Rafael’s research focuses on the Araucaria-grassland mosaic of southern Brazil’s high plateau, the planalto, and he had taken us to see some of his research sites in the Parque Nacional de São …...

The Araucaria War We arrived at the Municipal Museum of History and Heritage in Três Barras, located in the old railway station, just before its closing time of 5:00 p.m. on a Tuesday in early June.

In …...

Mount Tamalpais Moods On my recent “book tour” to the San Francisco Bay Area to talk about and promote my book Nature on the Edge: Lessons for the Biosphere from the California Coast, I had planned to stay at the UC Berkeley’s Point Reyes Field Station.

Nature on the Edge: California Biosphere Book Tour When I returned in late October to Falls Church, Virginia, a Washington, D.C., suburb where I’ve lived for more than thirty years, after a five-day, 3,000-mile drive from California, I had an old Joni Mitchell song stuck in my head: … / but I wouldn’t want to stay here/ it’s too old and cold and …...

The View from Mukuntuweap February 2024. The canyons here are eroded into mostly Jurassic strata that were deposited near sea level roughly 200 million years ago, and later folded up by orogenic forces that raised them to elevations of up to 10,000 feet. In the recent instant of geological history since our human species reached this continent, this landscape …...
