It is finally snowing here in Big Bear Lake, CA as I sit here writing this blogpost. It is long awaited as it has not really felt like winter at all in parched California with the warm temperatures and nonexistent precipitation. It is definitely going to be a dry summer full of fire.

Since my last blogpost I have been working on many things. Mary (my fellow CLM intern) and I are nearing completion of an invasive plant species identification guide for the Cleveland, Angeles and San Bernadino National Forests. It has been tough finding photos for the guide as it is January. We have managed to gather together a good many though.

We also have been helping Kerry Knudsen, a lichenologist out of UC Riverside, compile a lichen flora of the San Bernadino NF. This is a great experience for me because there are mostly crustose lichens out here because it is so dry. I am much more familiar with the large macrolichens from moister areas like northern California. I got to see a historical lichen collection from the late 1800’s from a southern California lichenologist.

I was happy to have a few field days that last couple weeks. One day we went out to the Bighorn Wilderness to see what kind of invasive plant species are out there and brainstorm about what species could invade next and in what areas. After the invasive plants guide we will be writing a wilderness management plan for the Bighorn. It was a beautiful day and a beautiful place! Another day we monitored riparian habitats for disturbance and it was great to see some wetter areas of the forest.

I hope you enjoy these photos!

This is a good example of an infestation of invasive English Ivy (Hedera helix) in a riparian area.

The invasive tree tobacco (Nicotiana glauca).

The flower of Nicotiana glauca.

Check out the berries on this manzanita! I think it is Arctostaphylos glauca.

Some awesome sandstone cliffs that we saw while out collecting lichens.

The giant chain fern (Woodwardia fimbriata) that we spotted in a riparian area. I would never have expected to see a fern this large in such a dry place like the SBNF.

The view east of the desert from the Bighorn Wilderness.

A really deep mine shaft that we saw on the Bighorn Wilderness.

I’m not sure what this cool lichen is…maybe a Caloplaca or Candellaria…

Astragalus albens, which is endangered.

The sensitive species Long Eyed Grass (Sisyrinchium longipes).

Dadder (Cuscuta sp.) is a beautiful parasitic plant that is vine-like.

The invasive castorbean (Ricinus communis).

A good looking Usnea phaea that is common on the SBNF.

I have been interning on the Mountain Top ranger district of the San Bernadino National Forest for three weeks now. The SBNF is located in the Transverse Ranges of Southern California, about two hours east of Los Angeles. I have been visiting the LA and Orange county area of Southern California my whole life because of family that lives there, but I had never been to these beautiful mountains before so I had no idea what to expect.

It is a world away up here. For one thing we are about 7,000 feet up and the air is clear and the water is delicious. Quite different from down in the city. There are large juniper and pine trees everywhere, and in different areas of the forest it is high desert. They receive enough snow in the winter to have three ski resorts, which I am very excited about. I am happy to say my view of Southern California being all city and no nature is completely wrong.

So far in my internship I have dealt with computer issues (getting my profile set up and whatnot), helped to close off and put up signs to discourage people from entering bald eagle habitat, marked brush piles not to burn that were potential wood rat and rubber boa habitat, and started writing an invasive plants species identification guide for the SBNF.

One of the coolest projects I am working on is a lichen flora of the SBNF. My other CLM intern colleague and I are working with a lichenologist, who works in the UC Riverside herbarium, to document the lichen flora of this amazing area. Lichens are my passion so this is very exciting for me. We have gone out collecting in the field twice and I went down to the university last week to learn about the database the herbarium there uses and enter some historical lichen collections from the late 1800’s. So cool! I am used to identifying macrolichens, the large lichens that are found in much wetter areas, so this is a completely new experience for me because it is so dry here. Most of the small microlichens we look at are growing as crusts on rocks, trees and on the ground in undisturbed habitat. I am learning to use a hammer and chisel to break chunks of the rock off the large granite boulders to take specimens back to the herbarium.

I am having a great time here so far because my coworkers and mentor are really helpful and welcoming. It is great that after three weeks I am already starting to feel like part of the family up here.

Next time I will post some photos!
