2004-2005 Berkeley High School

Heath & Marjorie Angelo Coast Range Reserve

The Angelo Coast Range Reserve is located on the South Fork of the Eel River in Mendocino County. The reserve provides a wealth of habitats for study, including river systems, redwood groves, mixed forests, meadows, and chaparral.

Half of Mrs. Mertens’ Berkeley High School AP Environmental Science class visited Angelo on October 15-17; the other half went on the following weekend from October 22-24. This album reviews photos from the first weekend. Click on an image to see an enlarged version.

The students arrived at Angelo on Friday afternoon. After getting settled, the class split into groups and competed in a scavenger hunt.

Students pack up with nets and binoculars to prepare for the scavenger hunt.

Santi, Laura, and Kendra show off some of their findings.

One of them is a Sceloporous, a.k.a. Western Fence Lizard.

After dinner on Friday evening the group headed out for a night hike along the creek. We found all sorts of great amphibians including Pacific Giant Salamanders, Foothill Yellow-legged Frogs, and a California Tree Frog.

We all woke up early Saturday morning to have plenty of time to check the traps that Jack, Tom, and Ryan set out the night before.

Everyone looks ready for a great morning hike.

This single Peromyscus mouse is the only thing we catch, even though we had set about 35 traps.

Without much luck in the mammal traps, it was time to set out on a hike to the White house. Along the trail, guess what we saw? River otters!

Adam and some fellow classmates make careful observations of the river otters in their field notebooks. The three otters give us a great opportunity to write a species account.

Kendra, Sara, and Desi love making field notes!

Jack shows off a Microtus (vole) tooth he found in some scat near the otter observation site. Jack sure likes scat.

Santi lets a millipede crawl onto her hand.

The rest of the group checks out the millipede’s groovy legs. Nisha seems amused, but Dessie has a different reaction.

For an evening activity, the group treked down to the creek and Ryan taught us about aquatic insects. Tom and Ryan demonstrated how to use kick nets to recover small aquatic animals that rest on the creek bottom.

Ben finds a good patch of insects and collects a few to keep for specimens.

Sunday morning began with rain, but the class made the most of the drizzle and embarked on one last amphibian hike. The wet weather brought out many Taricha granulosa (rough skinned newts) and Batrachoseps attenuatus (California Slender Salamanders) that were easy enough to find walking on creek banks.

This Taricha has bright orange coloring on its belly to warn predators that it is toxic. “Don’t lick me!”

Despite its small size, this is a full grown California Slender Salamander. Check out its tiny arms and legs.

Nisha and Santi hold the California Slender Salamander they found near the creek bank.
