Rinker Rock Creek Ranch will offer a four-day field course taught by Justin Trujillo, author of A Field Guide to Grasses and Grass-like Plants of Idaho. The course focuses on developing practical plant identification skills through hands-on learning in the field.

Day 1 introduces the basic morphology and identification of cool-season grasses, with a brief introduction to select warm-season species for comparison and field recognition.

Day 2 focuses on advanced grass identification using diagnostic characteristics and field keys, with a brief review of foundational traits to orient both returning participants and those attending independently.

For the course fee, students will receive a 6 x 8 inch plant press and a hand lens. Students enrolled in the grass portion of the course will receive a copy of A Field Guide to Grasses and Grass-Like Plants of Idaho.

Students can register for for the first two days for $250 or register for all four days here for $375.

This course does not include meals; those enrolled should plan to bring food/snacks, water, and if desired, a folding or travel chair into the field each day. Camping will not be available on the ranch because we house students and researchers for the summer. Here are some campsites nearby:

Register early - the course is limited to 20 participants per day.
