BioBlitz at Sagehen Creek Field Station

Registration link coming soon…

***Please note that there is a separate waiver required by the UC Sagehen Creek Field Station.***

Sagehen Creek Field Station Waiver - Please digitally sign and email to sagehen@berkeley.edu by Thursday, July 9

Join TINS staff and others as we document life in the Sagehen Basin during a morning bioblitz! A bioblitz is a detailed study of biodiversity in a specific location over a specific period of time, bringing volunteers and experts together.

Naturalists of all ages and skill levels are welcome. Just bring your smartphone or camera, and your enthusiasm, and together we will look for birds, mammals, insects, spiders, and wildflowers.

If you want to use the iNaturalist application on your phone, please be sure to download it prior to arrival. However, we personally prefer to upload images to iNaturalist from a camera later using the web interface and a computer, so be aware that also is an option.

Practice with making iNaturalist observations beforehand is recommended but not required.

Plan on reconvening at noon for lunch and a quick taxonomic tally. We also will have an optional afternoon session for those that want to spend a full day exploring, and we may even conduct insect light-trapping at the field station for a few hours the previous evening.

We will be sending more information out via email the week of the blitz, but if you have any questions in the meantime, you can contact Will Richardson

Odonates Mini-blitz
May
31

Odonates Mini-blitz

Join TINS for a fun day exploring dragonflies as part of our annual Odonates Mini-blitz in Truckee as we search for early season Dragonflies around Truckee’s Teichert Ponds and Cold Creek. Note that this is a day dedicated to exploration and learning, so no prior expertise is required. A willingness to get your feet wet, literally, is a plus.

What are Odonates?

Odonates, or simply “odes” for short, are members of the insect order Odonata, comprising dragonflies and damselflies.  This fascinating group of animals holds much the same appeal with nature lovers as birds and butterflies (i.e. diverse and conspicuous, aesthetically pleasing, ecologically interesting), and with the 2003 release of Tim Manolis' fantastic identification guide, Dragonflies and Damselflies of California, the group became that much more accessible to anyone with a pair of binoculars or a camera (although a net is still required for some identifications). The greater Tahoe region hosts about 55 species, including a few that are strictly migratory or occur as vagrants.

Each year, a group of California odonate enthusiasts (CalOdes) converges for a long weekend somewhere in the state for an Odes-Blitz, wherein they attempt to document new species for state or county lists. In the Tahoe region, TINS sponsors instead an Odes Mini-blitz, and our goals are threefold:  to (1) document the odonate fauna of the Tahoe region, (2) identify locations with high odonate diversity or hosting interesting species, and (3) have fun!

Some of the discoveries from these events have been quite significant. For example, in 2011 we documented the intergeneric copulation between two dragonflies at Grass Lake. In 2021, we rediscovered Spiny Baskettails in the Donner Lake area, a population that had not been seen since 1914! Click the embedded links to read more about these discoveries.

How to Get Involved

Anyone interested in participating in this or future mini-blitzes is encouraged to contact Will Richardson for more information and to get on the list.

Nature and Wellness Talk

Nature and Wellness Talk

Connection to Nature, Land Stewardship & Wellness

At the heart of Mountain Lotus is a commitment to wellbeing — for individuals, our community, and the Sierra ecosystem. The Mountain Lotus Speaker Series brings together leaders, educators, and innovators for conversations exploring the intersection of ecology, wellness, and community action.

This evening explores the relationship between connection to nature, land stewardship, and human health through two engaging presentations.

T. Will Richardson, Ph.D. — Co-Founder & Executive Director, Tahoe Institute of Natural Science
Dr. Richardson will discuss how developing a deeper relationship with the natural world — from observing backyard wildlife to exploring local ecosystems — cultivates a sense of stewardship that inspires meaningful action.

Peter Mayfield — Founder & Principal, NatureUP Health
Can getting out of the clinic and into the woods transform mental health care? Peter will explore emerging evidence for nature-based therapies as effective treatments for mental illness and how these approaches may complement — or reimagine — the traditional medical model.

A longtime social entrepreneur, Peter founded Whole Hearts, Minds & Bodies, a clinically supervised nature-based therapeutic mentoring program for youth and young adults facing severe emotional disturbance, complex trauma, and substance dependence. The program became the first in the U.S. to secure County Behavioral Health contracts and Medicaid reimbursement, marking an important step in bringing nature-based therapy into mainstream mental health care.

Join us for an evening of learning, dialogue, and connection as we explore how nurturing our relationship with the land supports both ecological resilience and human wellbeing.
