Biomimicry uses drone technology to drop seeds just like what birds do to restore denuded forests

The drone is called the galansiyang, named after the Asian Glossy Starling, a bird that drops seeds everywhere. Just like the bird, the drone also goes to places that are hard to reach.

It was developed in the Computer Applications Department of the College of Computer Studies at the Iligan Institute of Technology (IIT), Mindanao State University.

It morphed into the Galinsayang, a startup company incubated by the Department of Science and Technology (DOST) Northern Mindanao. It now leads a reforestation project at the Kalatungan mountain ranges in Pangantucan, Bukidnon.

The P5.5-million reforestation project will cover four hectares out of 21,000 has., according to Ritchie Guno, DOST provincial director for Bukidnon. The project is a collaboration between Galansiyang, the Protected Area Management Board (PAMB) of the Department of Environment and Natural Resources, DOST, and the local government.

Using drones, Galansiyang has a 90 percent success rate in reforesting land areas in Mindanao, Guno said.

It uses the seeds of balansihan, talingtingan, bagalug and ulayan, all endemic tree species. The seeds are coated with charcoal, manure, compost, clay, and a microbial inoculant, a slow-release fertilizer that supports plant growth. The mix is then shaped into balls.

Using 3-D printing, the drones are modified to carry and then drop the seed balls in reforestation areas.

The seed balls are prepared by students at the Bukidnon Community College, members of the Manubo and Kalatungan Mandum indigenous communities which collects the seeds in the mountains, and PAMB which approves the seeds used. The selection is based on the recommendation of the Central Mindanao University which has the data on Mt. Kalatungan’s endemic plants.

Mt. Kalatungan is the country’s fifth-tallest peak and home to at least 129 animal species and 342 plant species.

“Our methodology is founded on one of the natural ways of plant propagation with birds as seed dispersers,” said Jay Gajudo, chief executive officer of Galansiyang.

“Using drones, we can plant trees faster compared to manual tree-planting. One person can plant 480 seedlings in eight hours, while one drone can plant 8,366 seed balls in one hour.”

Galinsayang displays data on its digital platform, for easy monitoring, transparency, and to make data-driven decisions. (Malaya)
