A big part of The Monarch Sanctuary Project's mission is to raise awareness for monarch butterfly conservation. We envision a world in which monarchs and pollinators are treated with compassion and where safe, sustainable alternatives are used for gardens and natural habitats everywhere.

The monarch population has been on a decline for nearly 2 decades. As of July 2022, our beloved migratory monarch butterfly, scientifically known as Danaus plexippus, has officially entered the danger zone! Monarchs are now listed as endangered on the IUCN Red List.


One of the greatest threats to monarch butterflies is the loss of habitat, and creating habitat sanctuaries is how we can all help.

We are honored to focus our efforts on the following:​

  • Encourage and maintain natural habitats for pollinators

  • Offer digestible education that empowers people to build their own natural habitat

  • Build awareness and agency in our local communities

  • Grow and distribute native milkweeds and nectars

What We Do

Our Impact

The Monarch Sanctuary Project works to raise awareness for monarch

butterfly conservation and to help protect their habitat as they migrate through

Central Texas. We accomplished the following in 2023: 


Milkweed Grow Operation 


We all know how important milkweed is, but when was the last time you found native milkweed at your local nursery? That is why the Monarch Sanctuary Project started growing our own. From local and sustainable seed collection to cold stratification, we obsess over each step to ensure that monarch caterpillars have milky leaves to feast on.
