Christmas Bird Count
Dec
14

Christmas Bird Count

The 2025 South Lake Tahoe CBC is Sunday, December 14, 2025

If you would like to learn more about the CBC, please click here. Otherwise, please sign up today via the button above. The below text includes some information about the structure of the count.

Registration HERE

Option One: Join the Flock. If you want to chase birds on foot, skis, or even in a boat, we are looking for experienced and beginner avian enthusiasts to find birds in assigned areas. We will appoint individuals or small groups to specific locations throughout the count circle. Please let us know if you would like to be assigned to a specific area, and we will do our best to make it work on a first come, first serve basis.

Option Two: The Backyard CBC. For people that live within the count circle, we encourage folks to participate by counting the birds at your feeder or in your yards or immediate neighborhoods. This way, you can kick back, relax, and learn about the birds that inhabit your yard. Be sure to hang up your feeder a few weeks leading up to the count, so the birds get used to the location of your seeds.

There will be an optional pizza party to conclude the day at Sue Stevenson’s house. More details to come.
With both options the data will need to be submitted to TINS via email or regular mail. A map of the count circle can be found by clicking HERE.

There will be an optional pizza party to conclude the day at Sue Stevenson’s house. Thank you to Blue Dog Pizza for donating pizza to our amazing volunteers!

Wildflower Wednesday: Emerald Bay Search Party with Hugh Safford
Aug
27

Wildflower Wednesday: Emerald Bay Search Party with Hugh Safford

Join plant ecologists Molly Ferry and Hugh Safford for a guided 3+ mile hike near Emerald Bay in South Lake Tahoe. This hike is hosted by the California Native Plant Society, Tahoe & Sierra Valley Chapter- rain or shine.

The hike will include some off-trail walking over uneven terrain, covering 2–4 miles with about 500 feet of elevation loss and gain (down and back up the paved road). Restrooms are available at the boat-in campground.

At Emerald Point, we’ll explore a stand of massive old trees, including Ponderosa pine (Pinus ponderosa), Giant sequoia (Sequoiadendron giganteum), and Canyon live oak (Quercus chrysolepis). We will count 13 different tree species that occur at the site.

In the spirit of Molly’s Wildflower Wednesday Search Parties, we’ll also be looking for a short list of target plant species. Your observations will help update the classic book Plants of the Tahoe Basin (Graf, 1999).

Wildflower Wednesdays are task-oriented toward search party species and map hunts. Expect off-trail hiking and uneven terrain as we search for species that need their distribution clarified for an update to Michael Graf’s 1999 Wildflower Guide. This may mean bypassing other interesting flowers to prioritize reaching key sites.

What to Bring: Water, sunscreen, layered clothing, sturdy shoes, a snack, and a botanical loupe (if you have one). No dogs, please.

Meeting Point: Please park and meet at this precise Google Maps location near Emerald Bay. Parking can be challenging, but there is plenty of paved roadside parking where the boat-in campground road meets Highway 89. We’ll meet at the green gate at 10am, returning in an estimated 4 hours. There are also shuttles running from South Lake and Sugar Pine Point State Park to Emerald Bay.

No registration - just show up on time.

Odonates Mini-blitz
Aug
3

Odonates Mini-blitz

Join TINS for a fun day exploring dragonflies as part of our annual Odonates Mini-blitz.

Contribute to citizen science! Read below for more information.

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 unique or rare species, and (3) have fun!

TINS Discoveries

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. Note that the location(s) each year are TBD, and the timing is usually quite flexible depending on the group.

More information about the goals of the Odes Mini-blitzes can be found HERE.

Barker Pass Wildflower Hike
Jul

Barker Pass Wildflower Hike

Join botanist Gale Rankin for a walk north from Barker Pass along the Tahoe Rim/Pacific Crest Trail to see wildflowers, old-growth trees, and stellar scenery.  Our “grand finale destination”, per Julie Carville’s Tahoe’s Spectacular Wildflower Trails, is “a glorious seep garden of wildflowers that cascades down a hillside into an inviting meadow”.  On the way, we will enjoy views of the Desolation Wilderness, Lake Tahoe, craggy volcanic outcrops, and a short detour to the flanks of Barker Peak.  Along with the myriad flowers of the several seeps, rocky slopes, and forests, our hope is to find explorer’s gentian and catch the Sierra primrose in full bloom.  

The maximum distance for this out and back outing is 5 miles and under 1000 feet in elevation, with the goal of being back at the cars by 1:00 pm.   The pace will be determined by the group and the trip is appropriate for all levels of wildflower enthusiasts.  Bring your snacks, water, mosquito repellent, sunscreen, hat, and hiking poles (for those that use them). 

This hike is co-sponsored by the Tahoe & Sierra Valley Chapter of the California Native Plant Society.

South Lake Butterfly Count
Jul
20

South Lake Butterfly Count

In 2010, TINS initiated an annual butterfly count, centered on Osgood Swamp and encompassing much of the southern Tahoe basin (view map of count circle). The goals of the counts are threefold: to (1) gather data to monitor butterfly populations, (2) give butterfly enthusiasts a chance to socialize and have fun, and (3) to increase public awareness and interest in butterflies and butterfly conservation needs. Experts from around the state have joined the Tahoe count, and more experienced butterfly enthusiasts will be assigned to cover various portions of the count circle, either solo or in small teams. All are welcome, however. We primarily use the count to generate interest in butterflies, and beginners can have a great time learning the basics.

Anyone interested in participating, please contact Will Richardson to be kept up to date on the latest information regarding the 2025 count.

Barker Pass South Bird and Wildflower Walk
Jul
19

Barker Pass South Bird and Wildflower Walk

Our amazing volunteer, Lynn Harriman, will lead this joint birding and wildflower walk along the Tahoe Rim Trail/Pacific Crest Trail. This will be an out and back walk from Barker Pass Trailhead. The trail follows the contour of a hill with views west along Barker Meadow. Passing through Red Fir forest and crossing seasonal streams coming down from the slopes of a 7,904-foot hill. Several alpine meadows follow the streams, and the walk will pass through them. The maximum distance for this outing is 5 miles, but if there is lots to see and the pace is slower, it may be a shorter trip with the goal of being back at the cars by 1:00. Our hope is to see Lazuli Bunting defending alpine meadow territory and we will look for Brewer's Bishops Cap (Mitella breweri). We will have brunch along the way so bring your snack, water, mosquito repellent, binoculars, sunscreen, hat, and your curious brain. The pace will be leisurely. The elevation gain and loss is no more than 400 feet.

Bob Anderson Memorial Hike
Jul
12

Bob Anderson Memorial Hike

Bob Anderson was (among many other notable things!!) a TINS Board Member, whose life was cut tragically short in 2013. Each year we honor Bob’s memory with a beautiful hike among the wildflowers and scenery of Carson Pass, following the loop that Bob, Grace, and family took on his last day hike in July of that year.

All are welcome, whether you knew Bob or not!

We will meet at 8:00 at the Woods Creek trailhead parking lot and cast off from there. Directions can be found by clicking HERE. Note that this is a Fee Area parking lot; I believe the parking fee is now $10 (unclear if Interagency Passes are accepted).

Each year we alternate between clockwise and counter-clockwise, hitting either Winnemucca Lake or Round Top Lake first, followed by the other.

Keep in mind that this is a slightly longer outing than most of our bird or botany hikes, so be prepared for covering about 6.5 miles, and definitely bring water and a snack (and your swimsuit if so inclined!) for a break at Round Top Lake. After the hike, we will raise a toast to Bob back at our cars, so consider an appropriate beverage and perhaps something tasty to share.

BioBlitz at Sagehen Creek Field Station

Register Here

***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 Friday, July 4

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
