Join plant ecologist Molly Ferry for a guided wildflower walk at Shirley Canyon near Palisades Resort. Participants will explore native plants, meadow herbs, and understory flora while learning from Molly’s work updating the classic 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 at the Palisades Parking lot near off of highway 89 between Tahoe City and Truckee.

Note: Feel free to turn around halfway (before Shirley Lake bouldery section) or rally up to High Camp- 4 miles, 2,000 vert and take the TRAM DOWN (free).

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.

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 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.

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
