The beam of a red-filtered torch sketches the trunks ahead, leaves whispering as a slow, deliberate climber tests the branches above. On a warm Sri Lankan night, the slender loris — eyes wide and reflective — freezes like a question posed to the forest, then continues its careful search for insects and tree gums.

Wildlife
History
The arboretum began as a private tree collection by Sam Popham, a British officer, and expanded after being transferred to the Institute of Fundamental Studies; it retains older specimen plantings alongside native trees.
Conservation
Lorises are sensitive to disturbance and habitat loss; operators emphasize minimal-impact viewing, no flash photography, and staying on established paths to protect nocturnal species.

Use a red-filtered light
Guides favor red light to reduce disturbance; bring a headlamp with a red filter or ask if one’s provided.
Wear closed-toe shoes and long sleeves
Trails are uneven with roots and insects; sturdy shoes and long clothing cut scratches and bites.
Stay quiet and move slowly
Lorises are sensitive to noise and quick movements — keep voices low and avoid sudden gestures to increase sighting chances.
Limit flash photography
Flashes can stress nocturnal animals and are often prohibited; follow your guide’s rules on photography.
Headlamp with red filter
Red light preserves night vision and minimizes disturbance to lorises.
Closed-toe hiking shoes
Provides traction and protection on rooty, uneven arboretum paths.
Insect repellent (DEET or picaridin)
Reduces nuisance bites that can distract from slow, quiet observation.
Lightweight rain jacket
Useful during sudden tropical showers common in Sri Lanka’s monsoon months.
