Fifteen years after the murder of Leonard Co, the country’s foremost plant taxonomist known as the People’s Botanist, family, friends, and conservation advocates gathered at the University of the Philippines Diliman to honor his life and legacy through “Bayani Ko,” a day-long commemoration of tree walks, planting, and the unveiling of newly rescued images from his fieldwork.
“Ngayong araw na ito ay fifteenth anniversary ni Leonard, and we are commemorating his life and death,” said his wife, Glenda Flores Co, who led the annual memorial mass with their daughter Linnaea.
Co was killed on November 15, 2010, in Kananga, Leyte, alongside forest guard Sofronio Cortez and guide Julius Borromeo, when soldiers of the 19th Infantry Battalion opened fire on their botanical [READ]
“Leonard’s song in a time of flooding,” a moving story by science journalist Bless Aubrey Ogerio
“If a tree falls in a forest and no one is around to hear it, does it make a sound?”
This old riddle, according to Ronald Achacoso, head of the Philippine Native Plants Conservation Society, has become a fitting frame for a loss that still reverberates through Philippine science.
Fifteen years after botanist Leonard Co was killed by government troops while conducting fieldwork in Leyte, the question lands with a sharper weight.
His death—described by authorities as a case of soldiers mistaking him and his two companions for rebels—was followed by years of quiet and slow-moving justice, the kind of silence that dissipates the way an echo disappears into the canopy.
Leonard, forest guard Sofronio Cortez, and guide Julius Borromeo may have seemed to have died in vain. But a decade and a half later, their death in the forest may yet save us from an avoidable death before floods completely overrun our mountains [READ]
“Leonard Co, Bayani Ko” commemorates life, legacy of People’s Botanist
Quezon City, 15 November – Botanists and advocates gathered today at the Institute of Biology in UP Diliman to mark the 15th year since the murder of the world-renowned ethnobotanist Leonard Legaspi Co. Justice continues to elude the family after Co was gunned down with forest guard Sofronio Cortez, and guide Julius Borromeo, by soldiers of the 19th Infantry Battalion of the AFP in Kananga, Leyte. The botanist and his colleagues were conducting a survey of tree species for a forest restoration project of the Energy Development Corporation (EDC) when the soldiers mercilessly fired 245 rounds at the botanical team.
“As Justice continues to elude the family of the People’s Botanist, the Constantino Foundation’s is determined to ensure Leonard Co’s life and legacy is even more known across the archipelago. Leonard defines what nationalism truly is, not merely in terms of [READ]
