Propagule Collection Project

We’re collecting mangroves, and you can help, MANG!

Every year, mangroves are deforested, harmed by rising sea levels, or devastated by hurricanes and storm surge. To help further our planting efforts across Florida, MANG is launching a public propagule and seed collection project, and whether you’re a Mini MANG or a grownup, you can help!

Don’t worry, we built ya a step-by-step guide.

Check out our Propagule Collection Guide for more on how to recognize healthy MANGs, how to store them, and where to drop them off. It’s got everything you need to begin collecting in the wild and joining the mission.

Gather them MANGs

You can find red, white, and black mangrove propagules and seeds floating in the water, up small creeks, in the intercoastal waterway, and stacked up along seawalls or boat ramps. Don't collect any that are dried out, broken in half, or missing they're terminal bud. Healthy MANGs look like the ones pictured here.

You cannot collect propagules or seeds from state parks, national parks, or directly from trees, so be respectful of Mother Nature! We always want to make sure that the seeds are fully mature and ready to go into the next cycle of life, MANG.

Store them MANGs

Store your red, white, and black MANGs in a bucket, large bin, or anything that has a lid. Keep bins or buckets in cool dry areas where they are not exposed to the direct elements. The quicker you can get them to a drop-off location the better.

Storing for 1-3 Days: For the short term, you can use bins or buckets with lids to lock in as much moisture as possible to keep the mangroves from drying out.

Storing for 4-10 Days: If you are unable to make it to a drop of location within a few days, stack the propagules in the vertical position with the terminal buds facing up and the lid off. Add 5 inches of water and check daily to make sure your mangroves have enough water and are looking good. It is good to flush the water every two days to avoid that low-tide smell and let them MANGs breathe!

Join the MANG Family

MANG® is more than a business, it’s a community of like-minded individuals out to change the world, one mangrove at a time.

In 2015, twin brothers Keith and Kyle Rossin came together with one mission in mind – to change the world one mangrove at a time. Since then, we’ve built a global family of people who care about the water, environment, and the overall wellbeing of the great outdoors.

We are stoked to be leading the movement for environmental change and restoration of our coastlines. However, we can’t do it without you, MANG®! To learn more about our Buy One. Plant One. initiative, head over to Our Mission and see what we’re up to.
