Transformative tree planting event helps uplift Los Angeles neighborhood

Trees for #ArborDay and trees all year!

Trees can transform a neighborhood. People who grew up in areas with plenty of greenery may not realize how a lack of trees affects a community. Without trees, neighborhoods often experience some of the climate crisis’s harshest effects. Pollution, erosion, and extreme heat are just the beginning of what treeless communities can expect to face.

As one of the most pollution-burdened areas in California, the northeast Los Angeles neighborhoods near Ascot Hills Park understand what it’s like to live with these issues. That’s why grassroots community organization North East Trees teamed up with the Arbor Day Foundation for a tree planting event on Tuesday, April 18.

Sponsored by U.S. Bank, the event saw organization members and locals work together to plant trees at Ascot Hills Park in Los Angeles. These trees are a powerful tool for improving air quality, creating shade canopy, and reducing erosion in the area. Trees also help cool down urban areas vulnerable to the heat island effect.

During the April 18 tree planting event, volunteers helped plant 45 trees. The plants were propagated from seeds collected in Ascot Hills Park and cultivated in the North East Trees nursery. This community-led nursery champions youth empowerment through partnerships with community organizations and local schools.

Five tree species, from coast live oak to black walnut, were planted during the event. Volunteers ranged from first-time tree planters to experienced organization leaders. As a spokesperson for North East Trees said, “People were enthusiastic and inspired to be surrounded by their work community and to participate in environmental activities outside of their normal environment. For at least one participant, it was their very first time planting a tree and they got to share that experience with people they have worked alongside for years.”

Occurring just before Earth Day on April 22, the tree planting activity remains poignant on Arbor Day, April 28, and year-round. L.A. locals looking to get involved can join North East Trees for volunteer opportunities on the first Saturday of every month. These events invite people of all ages to get active outdoors.

Through the Arbor Day Foundation’s partnership with coconut water company Vita Coco, social media users can also use the hashtag #ArborDay on Instagram, Twitter, or Facebook to plant up to 100,000 trees in total.

How to build a DIY bee house for Earth Day

It’s the bee’s knees.

Need to add some buzz to your life without caffeine? Bee houses might be perfect for you. While building and maintaining a bee house isn’t for everyone, it is a great way to be a friend to these little critters. Most people have heard about the issues bees face, and many know how important bees are as pollinators. So, how can you help support these important insects? If you don’t have the green thumb required for a pollinator garden, consider setting up a DIY bee house for Earth Day (April 22) this year.

But wait! Before jumping into this project, there are some things you should know first. Unfortunately, even if you have the best of intentions, it’s possible to cause more harm than good when setting up a bee house.

As Gwen Pearson, an entomologist at Purdue University, told Earther, “It’s such a fantastic desire to be helpful and fix the things we see that are broken around us. That’s wonderful and I honor that so much, but the problem is the world is really complex.” Before building a bee house, research native bees in your area. Not all species will benefit from a bee house, and many bees throughout the United States are solitary creatures.

Prospective bee house builders should also know what maintaining a bee house entails. If these structures aren’t cared for and kept up, they can attract pollen mites. These mites can steal food from bees and even latch onto them. Avoid issues like this with routine bee house cleaning and maintenance. Only install a bee house if you can commit to monitoring it for moisture, pests, and predatory birds.

If you’re not scared off by these stipulations, then congratulations! You might have what it takes to keep a bee house in your yard. Here’s what you’ll need to get started.

DIY bee house materials

Before building, gather the right materials and know which materials to avoid. Speaking of materials to avoid, don’t build with bamboo. This reedy material can trap moisture, which isn’t ideal for bee houses.

Instead, build with untreated pine wood, or even harder woods. The main structures in your bee house will be wood blocks with hollow tubes in which bees can nest. Cardboard tubes and paper straws can be used to create these tubes.

Bee house building instructions

Bee houses can vary from simple container homes to multi-level bee hotels. If you want to start with a simple container home, repurpose old containers. Thoroughly clean your container of choice, poke holes in the sides to create air vents, and fill the container with paper straws or small cardboard tubes. When placing the container home, choose a spot where it will be sheltered from wind and rain. Too much of either will disturb the bees. Crown Bees can provide further guidance if you face issues during your build.

Pros seeking a more involved bee house set-up may want to explore designs for a bee hotel. These larger structures can feature several levels of nesting trays for bees.
