Phil Hardberger Park Conservancy Joins 'Following the Flight of the Monarchs' Project with Installation of Streambox
The Phil Hardberger Park Conservancy is proud to announce the installation of a streambox broadcasting the serene sounds of the Historic Voelcker Homestead, situated near the Butterfly Learning Center within Phil Hardberger Park.
Nestled in the heart of San Antonio, Texas, Phil Hardberger Park spans 330 acres and is home to the iconic Robert L.B. Tobin Land Bridge, the first of its kind in the United States, developed for shared use of wildlife and people.
Celebrated for its natural beauty and biodiversity, Phil Hardberger Park offers sanctuary to over 176 species of birds, more than 60 species of butterflies, eight species of bats, dozens of species of moths, and many more. Despite being surrounded by urban development and proximity to the airport, the park’s soundscape is a harmonious blend of nature and urban life.
The streambox was installed as part of the 'Following the Flight of the Monarchs' project. It is the third installation of open microphones meticulously placed by renowned sound artist and acoustic ecologist, Rob Mackay.
This groundbreaking interdisciplinary acoustic ecology project aims to trace the migration routes of Monarch butterflies as they embark on their awe-inspiring 3,000-mile journey between Mexico and Canada twice annually.
Since its inception, 'Following the Flight of the Monarchs' has captivated audiences worldwide, connecting ecosystems and communities along the monarch butterfly migration routes.
Phil Hardberger Park proudly joins the esteemed locations participating in this initiative: Cerro Pelón UNESCO Monarch Butterfly Reserve in Mexico (est. 2018) and Point Pelee National Park in Canada (est. 2019).
These streams not only serve as invaluable tools for ecosystem monitoring but also poignantly remind us of the urgent conservation efforts needed to safeguard the Monarch butterflies. With populations declining by nearly 90% over the past two decades, initiatives like 'Following the Flight of the Monarchs' play a vital role in raising awareness and fostering conservation action.
For those eager to immerse themselves in the tranquil sounds of nature, tune in to the streambox at Phil Hardberger Park via the Locus Sonus Soundmap and embark on a sensory journey unlike any other.
