the elegant script of ferns. . .*
Last February, we took our visiting oldest daughter to Nyungwe National Park and hiked the first half of the trail that includes a tree canopy walkway. Last week, with second daughter and friend in tow, we completed the entire circuit.
The hike started with us tucking our pants legs into our socks (against ants) and receiving walking sticks.
Although the paths are well-maintained, the sticks are necessary for the steeper, sometimes slippery sections.
The steps shown above are the first of many, many, many on a long descent to the canopy walkway. (The welcome center is at one of the highest points in the park.)
It was a hazy day, so I can’t show you the great mountain views that are otherwise visible along the way, but you can click here to see my photos from last February.

Above: Our guide led the way. He spotted a number of blue monkeys and turaco birds for us.**
(The earth walls that were cut when the trail was created — to the right of the guide above — bring the smaller plants of the forest floor to almost eye level. I’ve put pictures and names of some of them in a photo gallery, which you can scroll through by clicking on ‘Continue reading’ at the end of this post.)

Above: We arrive at the beginning of the canopy walkway.

Above: The middle and highest section is 187′ (57 m.) above the ground.
During last year’s visit, with only the three of us and the guide, the walkway swung less, and I stopped a few times to look down and take pictures. (You can see them here.)
This time, in a group of about fifteen — with eight people crossing the walkway at a time — the shaking made me keep my eyes on the back of the person in front of me.

When you cross the middle section of the walkway and (dare to) look down, you see a narrow valley of tree ferns and hear the moving water of a stream. The second half of the hike continues on to that valley. There, we saw hundreds of the tall ferns.
In fact, this trail is named — in Kinyarwanda — for the tree ferns: the Igishigishigi Trail.
Cyathea manniana is one of two tree ferns in the park. The other is C. dregei. Manniana only grows in undisturbed forest, while dregei can be found along the sides of the road through the park (it also has persistent old leaves).
Above: Looking up into the ferns. C. manniana can grow to almost 20′ (6 m.) tall.
“C. manniana is traditionally used as a medical plant to treat snake bites,” according to my field guide.*** There are nine kinds of snakes in the park, but only one is poisonous.

Above: A small bridge crosses the stream that we heard from the canopy walkway. The guide meant to take us down to the water, but there were too many biting ants on the path.
Tree ferns are one of my favorite plants, but unfortunately, they would not grow well in the cold or the heat of our Washington, D.C., garden.
Above: Leaving the ferns behind, we started back to the welcome center.
The Igishigishigi Trail is 1.3 miles (2.1 km.) long and takes 1 1/2 to 2 hours. It is rated ‘easy,’ but a large part of it involves descending and ascending steps. It’s a solid workout.
The trail begins at an elevation of 8,038′ (2450 m.) and descends to 7,530′ (2295 m.).
Above (on the right): Nearing the final set of steps, we found a large group of Lobelia gibberoa or giant lobelias.
With their long candles of greenish white flowers, the plants can grow to 29′ (9 m.) in height. Latex from the stems is traditionally used to treat irritation from stinging nettles.
Above: After the hike, we went back to the Nyungwe Forest Lodge on the Huye-Rusizi Road. The yellow flowers along the edge are a Senecio species.

** It’s also quite possible to see turacos flying from tree to tree from the pool at the Nyungwe Forest Lodge.
***An excellent book about the park is the Illustrated Field Guide to the Plants of Nyungwe National Park [of] Rwanda by Eberhard Fischer and Dorothee Killman. It’s 770 pages long, with color photographs of 650 plants. You can buy a copy here. Unfortunately, it’s $71. Some copies were printed for the Rwandan tourism office, and I bought mine in a Kigali bookstore for about $25, but I haven’t seen any on sale here for about a year.
