It's a hot, breezy summer day in Los Angeles.

I'm just recording the sounds of my neighborhood here.

In the Huntington Park neighborhood, you might see a woman named Eileen Garcia driving from tree to tree trying to give them some much-needed relief from the heat.

So my first tree, I'm stopping it as a crate myrdal.

It was planted about six months ago as a replacement tree.

And it's drying out. It's gotten scorched by the heat wave that just passed.

Eileen parks next to the tree, then heads to the back of her truck, where she's got a 300 gallon water tank with a hose.

I took priority for this particular tree since it's so scorched as getting the 15 gallons of water into it, which is basically about three buckets worth.

And putting down a layer of mulch to protect that from that rapid evaporation.

This is a part of Eileen's job. She's the regional manager in Southeast LA for tree people, an environmental nonprofit that aims to plant more trees in the city.

In recent years, tree people has been planting trees in areas like Huntington Park that historically haven't had a lot of trees compared to other parts of the city.

Research shows that urban neighborhoods impacted by redlining or racist housing policies in the 20th century have far less shade compared to more wealthy, predominantly white neighborhoods.

It's hot. It's mostly cement. A lot of the homes are built pre-1950s, so that means there is an air conditioning because it's a lower income communities.

Less shade means less relief from hot summer days, which are only going to increase due to climate change.

But the solution isn't to plant more trees. Tree care can be expensive, time consuming, and require a ton of communication with the local community.

Eileen stops at another tree, a gold medallion that's easily identified by its big yellow flowers.

I see that this tree has had the stake removed for whatever reason. Sometimes they just break and residents remove them.

So what we try to do is make sure that we put these stakes back so that way the tree will grow nice and straight and it'll give it that reinforcement.

She gets out some tools and starts hammering the stake back in.

And there we have it, nice and straight. It's so beautiful. This canopy is absolutely gorgeous. These vibrant yellow flowers against the blue sky is just phenomenal.

She's here to help take care of the trees so that everyone can enjoy them, including her neighbors.

This is where I live, so it became very, very near and dear to me to want to really support our efforts to increase tree canopy in regions that don't have them.
