Weekly Nature Question #4: What Species Of Frog Is This?

My Weekly Nature Question is about my asking for help from the blogosphere (and other internet users) to learn about species living in Angeles Forest and to share that learning with others.  I’m really hoping that this turns out to be a viable and meaningful way to share knowledge.

The answer to last week’s tree question turned out to be a  Great Basin Collared Lizard.  As more information is shared, it will appear on the Great Basin Collared Lizard Forest Life Page.

I’d like to extend thanks to:

Alex Gurrola for being the first to correctly identify the species and providing a link to more information and to Eric Kuns (my brother) for confirming the identification and providing a more specific link.  I also want to say thanks to blogger Henry Mowry of the blog Mowry Journal for checking with his naturalist son to confirm the identification and to verify that the species was within its home range and therefore unlikely to be someone’s former pet.  Thanks also to everyone else who commented on this question.

This week nobody sent me any links to blog articles and I was unable to find any through the search feature in the WordPress reader.

This Week’s Question:  What species of frog is this?  I saw several dozen of these frogs on a hike through Shortcut Canyon on the Silver Moccasin Trail with my brother.  We shared the camera that day, so I’m sure some of the photos below were taken by him (I’m just not sure which ones).

Death and Continued Life Along the Silver Moccasin Trail to the San Gabriel River

Hiking the Silver Moccasin Trail from Angeles Crest Highway down to the San Gabriel River is a journey crisscrossing burn areas showing signs of forest regeneration with areas that survived the Station Fire.  Much of the time the trek feels as though one is walking through a quilted landscape with patches of burn, patches of regeneration, and patches of forest that survived in view simultaneously.

I found this tapestry simultaneously sad and hopeful.  The obvious sadness I felt while thinking about what was lost was tempered with constant exposure to what remained and what was regenerating.

When I first hiked this trail in June 2011, the flowers were in full bloom.

Up near the top of Shortcut Canyon the blooming flowers were what made the process of forest regeneration so apparent–especially in areas where it was clear that there were no shade trees in the past.  The purple flowers are from the Poodle Dog Bush and can cause a rash.  Seeds from these flowers remain dormant over long periods of time waiting for fires to wake them up.  While the Station Fire was a disaster of human origin, I find it helpful to think about the fact that fire is inevitable in the forest  and that some plants are lying around waiting for fire in order to cause their birth.

In parts where the charred remains of shade trees were dominant, what was lost became more prominent.  Without the foliage however, views were less obstructed.  Almost like finding out something you didn’t know about someone at a funeral, there were far off vistas to see that were previously blocked.  Like people, there is more to the forest than can be seen from one perspective.

Part of what makes this particular hike hopeful is that about halfway down Shortcut Canyon the trail follows a stream leading to the San Gabriel River.  Where there’s water there is usually life.  Seeing creatures living in the area helps bolster the feeling that eventually the forest will return again.  My dominant thoughts through this area of the hike were focused on what is alive and starting to flourish.  During a hike in August 2011, my brother and I saw around a hundred frogs and tadpoles along the stream.

The trail ends at the San Gabriel River (which in many spots appears unaffected by the fire).  Across the river is the West Fork Trail Camp.
