Every December it is my privilege and pleasure to lead a group of DP I (Grade 11) OSC students up the slopes of Sri Pada in order to study the mountain’s ecology and appreciate its value as a stronghold of biodiversity in a rich Sri Lankan cultural landscape. This year I invited the DP Biology class and their teacher Tim Getter to join our group of eleven DP ES&S students. We were supported by our teaching colleagues Sonalee Abeyawardene and Celine Dary (so there were added opportunities to explore ideas of pilgrimages in literature and converse in French during our three days out!). Several students had just completed a heart-pounding SAISA tournament in Muscat and hopped from their airport bus onto ours as we headed up into the Central Highlands on a clear Monday morning.
For all students, be they biologists or ecologists in ES&S, the three-day visit to Sri Pada and the Peak Wilderness area offers a unique opportunity to conduct field studies in a biologically rich but anthropogenic influenced landscape. The trip is a unique learning experience, one that is perhaps less appreciated by students in the moment but invariably remembered with great fondness. As usual, we based ourselves at the Moray Estate Fishing Huts. These three rustic cabins are rented out to ecotourists and people willing to put up with simple amenities in order to experience a uniquely beautiful location. Significant time was spent simply getting to the huts and back but once at the Fishing Huts there were all sorts of opportunities for learning. The huts lie at the boundary between manicured tea estates and mid-elevation sub-montane tropical rainforest. This year I highlighted four themes of study for the trip:
- Theme 1: Land Use Variation (anthropocentric vs. natural ecosystems)
- Theme 2: Forest & Vegetation Types
- Theme 3: Vertical Zonation
- Theme 4: Biodiversity in a ‘Biodiversity Hotspot’
Our main study day was on Tuesday December 10th (my brother Brian’s birthday!) when the ES&S class ascended the peak. Based on the fitness and gear that the group, I decided to make it a day trip and not spend the night on the top. We went with light packs for the day and were able to conduct a series of line transects as we gained altitude on the peak. The idea was to observe and record changes in plant diversity as we traversed human and natural landscapes and gained altitude on the peak. I had decided to leave my heavy camera gear in Colombo and was armed with a lightweight Canon Powershot, GPS and small temperature probe. The small allowed me to take quick snapshots of the wealth of plant life on the forest trail- and the detail isn’t too bad. Because the hike is physically demanding, there was little time to linger but the group managed at least five transects at different elevations and habitats. We got to the temple around 1:00 –it was pleasantly empty as the season was still a week away from starting. Our lunch of peanut butter and Nutella wraps was shared with a wandering Australian, we rang the temple bells, appreciated the summit temple and then headed back down. One of the students- Max who had been in Muscat playing football for OSC -had a sore knee and we took the last bit slowly. This facilitated a meandering conversation and time to observe the forest much more closely. It was dark by the time we got back to the Fishing Hut.
On the final morning we were able to look at a patch of degraded forest and a eucalyptus plantation. These habitats offer a fascinating contrast to the sub-montane forest. There are numerous invasive species colonizing these disturbed areas but also a gratifying number of native species also making a start. Down below us the biologists completed a biotic index study of two streams (one from the forest and one from the tea estate). We were moving back to Colombo by 10:30 and school wrapped up two days later. Now, as we begin a new term, the classes will be sifting through their data, science journals, photographs and memories to consolidate their learning on Sri Lanka’s sacred mountain.
