An ecotone is a transition zone between two ecological systems. Ecotones can range in size: in some places ecotones are wide (e.g. forest – grassland ecotones), in other places they are quite narrow (e.g. riparian – arid shrub steppe). In […]
Last April, Jason and I surveyed lichens in the northern Mojave. It’s the second field season of a three year study involving lichen biodiversity along the ecotone of the Great Basin and Mojave Deserts in Southern Nevada. And what did […]
Part 1 covered the hike, but we didn’t touch at all upon the lichens on Mt. Whitney! So let’s do that here. Firstly, you might be wondering – what’s the history of lichen collections of Mt. Whitney? Two words: its […]
Mt. Whitney, the tallest mountain in the conterminous U.S., looms over the Owens Valley, once a thriving agricultural area, now increasingly arid as its the major supplier of the Los Angeles water supply. It’s a striking landscape characteristic of the […]
Dear Kearsarge Pass, With your striking red furrowed bark of Foxtail Pines, cousin of the Bristlecone Pines. Soft rounded valley formed by the ancient lapping of glacial tongues. And alpine lichens slowly crawling on the teeth of giants. Loved every […]
Its hard to remember all the great articles that one comes across during the course of a day, but there’s always a few that seem to pop out and need to be acknowledged, remembered, noted. The two prominent ones from […]
Bishop Pass is one of the more species-rich alpine locations in California that Imshaug collected in during his 1955 surveys. Despite the lack of well-developed soil, he found a number of soil crust lichens (terricolous lichens), along with dozens of […]
Giant fires raged last year when Jason and I attempted to survey two alpine lichen locations in Washington: Mt. Pugh (Glacier Peak Wilderness) and Mt. Tiffany (Okanogan National Forest); the 2015 fires shut down many of the towns in the […]
Waiting for alpine lichen season to begin is challenging, but Jason and I have been spending the past month adventuring around Idaho, Washington, and north-central B.C. My favorite by far has been the Trophy Meadows in in the Upper Clearwater […]
Our first field hitch of 2016 turned out pretty great, we surveyed lichens at seven collection areas, for a total of 32 sites, and brought home about 700 collections. But those are just numbers, the fun part is the places […]
