Fire has been shaping Eastern Sierra landscapes for centuries. Human interactions with fire in the Western United States have greatly influenced wildfire type, severity, and its effect on forest ecosystems, creating management challenges across the region. If you are interested in learning more about wildfire and its role in shaping forest ecosystems, you’re in luck! There are still spots available in Malcolm North’s Fire Ecology of the Eastern Sierra field seminar, coming up September 9–10.
When considering the ecological effects of the Hetchy Hetchy Reservoir, we tend to think of the initial flooding of Hetch Hetchy Valley. But are there also ongoing ecological consequences downstream of the dam?
This week’s Refreshing ‘Ologist, Dr. Jeff Holmquist, will compare conditions below the dam, above the reservoir, and in reference sections of the Merced River to help answer that question. Along with the ongoing effects of the reservoir, he will also discuss river-wetland linkages and the ways in which river flows have been manipulated in order to mitigate effects on wetlands. (more…)

Our refreshing ‘ologist for this week is researching techniques in parks to be used for monitoring and managing aquatic wildlife. Join us this Wednesday, August 23 at 4:00pm in the Mono Lake Committee gallery to hear about how scientist Colleen Kamoroff uses eDNA in water samples to learn more about an area and the species that occupy it.
DNA obtained from filtered water samples is often referred to as aquatic environmental DNA or eDNA. eDNA is a promising tool for monitoring (more…)
If you have ever wondered about how songbirds are studied and why, you should come to the Mono Lake Committee this Wednesday, August 16 at 4:00pm to hear from this week’s Refreshing ‘Ologist, Michelle Desrosiers.
Scientists in the park have been monitoring the status of songbirds as well as collecting information about their natural history to better inform conservation and management decisions. Songbirds serve as indicators of functioning ecosystem processes due to their position in the food chain, their diverse habitat requirements as a taxonomic group, and their accessibility to study.
In Yosemite scientists use songbirds to (more…)
Ever wonder about the carbon storing potential of Tuolumne Meadows? If you have, you’re not so different from our researcher for this week’s Refreshments with Refreshing ‘Ologists. Come listen to Lydia Baldwin present her research in Tuolumne Meadows on Wednesday August 9 at 4:00pm to learn more!
Wet meadows throughout the Sierra Nevada that were historically disturbed are currently losing both soil-water holding capacity and the ability to store carbon. These wetlands formerly functioned as sinks of carbon dioxide, but now they could act as significant contributors of CO2 into the atmosphere. Furthermore, the maintenance and addition of carbon to soil can also enhance its capacity to hold water. This refreshing ‘ologist is testing whether the reestablishment of a sedge-dominated community at Tuolumne Meadows, a high-elevation wet meadow in Yosemite National Park, will restore the meadow to a carbon-accumulating ecosystem.
Join us to hear Lydia explain how she monitors gross primary production and plant respiration to create a model of growing season carbon dynamics to determine if these treatments increase the meadow’s carbon storage. Be ready to learn and ready to eat because admission and snacks are both free!
If you’re interested in how carnivores are being managed in the Eastern Sierra, join us this coming Wednesday, August 2 at 4:00pm in the Mono Lake Committee gallery.
California Department of Fish & Wildlife (DFW) environmental scientist Jonathan Fusaro will explain carnivore research and management, as well as what DFW’s Bishop field office is doing for research and management of carnivores locally. Jonathan studied black bear populations for his master’s degree in wildland resources from the University of Utah. Now Jonathan works closely with researchers to manage black bears and is heavily involved with the Eastern Sierra Black Bear Project.
If you want to find out more about the management and research of carnivores, come to the Committee gallery this Wednesday afternoon. Admission and snacks are free. Hope to see you there!
Join us for this summer’s first Refreshments with Refreshing ‘Ologists presentation, next Wednesday, July 26 at 4:00pm in the Mono Lake Committee gallery!
Come hear hydrologist Sue Burak give an inside look at the work of an avalanche forecaster, the science behind the forecasts, and the headaches of an avalanche forecaster during a winter when nature put the hammer down in a presentation entitled “Atmospheric Rivers Bring It On: Big Storms & Big Avalanches in a Record-Breaking Winter.” Admission is free and there will be free snacks!

Over the past winter, the Mono Basin received record levels of snowfall—estimated runoff was at 206% above average for Rush and Lee Vining creeks at the end of May. According to ASO Principal Investigator Dr. Tom Painter, over a three-week span during January the Sierra Nevada received more water than the entire Colorado River basin receives in an average year. In the first week of July Saddlebag Lake Resort reported 12 feet of snow still on the ground—that is a lot of snow for July.
With spring in our pocket and summer upon us, the time has come for warmer weather, and Mono Lake has been at times rising a twentieth of a foot per day. This added up to (more…)
We are excited to announce that we are offering free educational interpretive programs and activities on the front patio of the Mono Lake Committee, Tuesday through Saturday at 11:00am. We will explore topics such as how the Mono Basin formed, bird adaptation, Mono Lake’s changing habitats, following animal tracks, and we’ll also make recycled crafts.
Our forming the Mono Basin program will focus on the different types of rock in the Mono Basin. It will introduce visitors to the varied landscape of the Mono Basin and what makes it so unique. Join us for a chance to make your very own tufa! (more…)
