New! Explore Phil Torres' photographs from the expedition in bioGraphic.

On a tiny island off the Malaysian coast, an ancient rainforest overlooks a modern metropolis. The thriving, 130-million-year-old ecosystem atop Penang Hill was the subject of its first-ever floor-to-canopy biodiversity survey—or bioblitz—in October 2017. Led by Dr. Meg Lowman and a team of Academy experts, an international cohort of 117 scientists logged over 1,400 observations of plants and animals using iNaturalist, and discovered at least four new species and observed 25 plants and animals never before seen in Penang or peninsular Malaysia.

The findings from this expedition illustrate the incredible breadth of the island's biodiversity—and could help Penang Hill achieve a listing as a UNESCO biosphere reserve. 

This project would not have been possible without the generosity and expertise of The HabitatUniversiti Sains Malaysia, and JASON Learning

Field Notes

Search #PGHillBioBlitz2017 and #CASfieldnotes on social media for more field notes and photos.

Day 1
In the field for just one day and Academy scientists are already making discoveries! Lauren Esposito, Assistant Curator and Schlinger Chair of Arachnology, along with post-doc Stephanie Loria, spotted what could be a species of scorpion previously unknown to science. Score!

Day 2
Using a variety of trapping methods (including the aptly named malaise trap), the team identified a number of fly, ant, and spider species—as well as a giant millipede.

Days 3-5
Field note roundup, organized by altitude. Canopy-level: Ant experts from Universiti Sains Malaysia modeled high-tech harnesses as they conducted research along the treetop walkway. Understory: Academy botanist Nathalie Nagalingum demonstrated proper fern-pressing technique in the understory. "Forest" floor: Academy sustainability fellow Durrell Kapan takes a selfie break with USM students.

Day 6
Making news in Malaysia! Lauren's (likely) new scorpion species experiences a brush with fame in the Sin Chew Daily

Day 7
The team ventured out of the forest to explore George Town, a UNESCO world heritage site. With luck, this expedition's bioblitz will help the forest atop Penang Hill achieve the same designation.

Day 8
By day, a local birder named Irshad helped Academy curator Jack Dumbacher's team capture birds just long enough to record their species before releasing them unharmed. As the sun went down, the scorpions came out—and the blacklights came on. Why? Any entomologist worth her spotting scope knows that scorpions fluoresce under UV light.

Day 9
513 observations of 210 species—and counting! Mammal-lovers will appreciate the following observations: dusky leaf-monkey, red giant flying squirrel, and Sunda flying lemur.

Day 10
Today's action was in the understory: The mammal team, led by USM zoologist Dr. Nadine Ruppert, successfully ID'd and measured 11 small mammals—including a white-bellied chestnut rat, which was scientifically determined to be adorable.

Day 11
That's a wrap! The epic Penang Hill bioblitz has drawn to a close. The team presented some impressive initial findings at a post-bioblitz symposium in George Town—1,600 species observations!—and will spend the next few months analyzing data and perhaps confirming the discovery of myriad species previously unknown to science.
