A Few Plants at Famosa Slough

Last month, on November 23rd, my girls went over to Famosa Slough because I wanted to check out and see how the plants were doing. I knew that the toyon and buckwheat were in bloom, but what other surprises were we in for? Well, I can tell you upfront that I saw my very first California boxthorn bush! Have you ever seen one in the wild?

So today, I wish to keep things casual, seeing that I have written more in-depth about almost all of these plants.

Please see the links down below if you would like more information.

A Few Famosa Slough Facts

First and foremost, the Famosa Slough is a living wetland preserve as well as a Marine Protected Area, which means nothing is to be touched or taken. It survives as a wetland by the tidal flow from the culvet pipes that connect it to the San Diego River Channel.

It consists of two sections: the Northern Channel,, which is 12 acres, and the southern portion of 25 acres of mixed wetlands. The more south you go, the less saline the water.

I have been here four times now and have written about Famosa Slough before, only concentrating on the southern section. Well, today,, we explored both.

North Channel of Famosa Slough

The North section connects to the San Diego River Channel to the north,, with the southern portion just across the street.

The small trail over here runs parallel to a few apartment complexes. Also, there might be someone sleeping in the larger bushes.

Pay attention to your surroundings.

South Area- Famosa Slough

Today was the first time I parked on West Point Loma Blvd and started our adventure first over in the Northern Channel and then crossed the street and started at a new entrance point.

I had no idea that there was a bench over here!

In fact, there are five benches scattered around Famosa Slough.

As we continued to follow the trail due south, I was pleasantly surprised at how much restoration work has been in progress since the last time we were able to visit over here in 2018.
