Everybody won on the two day Forest Ecology Course held in Dargle recently. Eugene Moll, who lives in Cape Town now, got to spend time in the forests he remembers so fondly from his student days, to relax on the veranda of Crowned Eagle Cottage listening to tree dassies call at night and to stir up some controversy around the trees we thought we knew. All his favourite things!
Participants were enchanted by his enthusiasm and knowledge and couldn't believe their luck at having such an expert on hand for a few days. The gorgeous Cairn of Old Kilgobbin provided the perfect venue beside the mist belt forest, the days were sunny and there was hand-made lemon cordial on tap. Life doesn't get much better than this – especially when you are learning about something as special as our forests.
One thing we all learned was to QUESTION things. To think about what makes a peach a peach, for instance. If we understand the basic characteristics of familiar plants we find in our gardens, we will have a much easier time trying to identify new trees.
Everyone was keen to try our they plant id skills using the Keys in various Guide books. Just to confuse everyone Eugene included two samples of Kiggelaria Africana (Wild Peach) – one branch from a mature tree and a twig from a little sapling. They were COMPLETELY different and had everyone puzzled for ages.
Eugene was rather disparaging about many of often difficult to use and 'unfriendly' keys. The botanical jargon is hard to understand, descriptions of many characters are too general and photos are non-specific. "What is the point of a photo of the entire tree, when all you can see in the forest is the bark?" he asks. So we learn that the Guide books are exactly that, guides. Nothing beats in the field observation. Walking, looking, feeling, tasting and comparing. "The same trees can be completely different from one area to another" commented Eugene, in awe of the huge specimens of Dais cotonifolia we came across. "In the Cape these are tiny scrubby things," he told us.
Eugene has produced a book called What's that Tree? A starter's guide to the trees of southern Africa, which he believes does a good job of highlighting the diagnostic features of each species – for example if 'three veins from the base of the leaves' is an important feature, he includes a picture of exactly that. Richard Booth, from Karkloof commented "I really enjoyed Eugene's wisdom."
Most of the course we spent outdoors under the forest canopy. Each tree has a little space around it if viewed from the air, we learnt. The tree tops brush against one another and keep each tree separate.
We came across an old logging pit where a Yellowwood had been felled many years ago for use in local houses. This illustrated perfectly how we have now lost the ability to live locally, on local resources. We have become 'Biosphere people' using resources from all over the globe in our daily lives.
Kathy Milford won't forget the course in a hurry. "The most memorable thing for me was the crazy expert peering through his treasured old magnifying glass with a chipped frame, at a little leaf and his saying 'this must be a Diosypyros whyteana, look at those orange hairs on the edge of the leaf'. That was a special moment, and when I looked through the magnifying glass there were the most beautiful little orange hairs that became larger than life. I felt like Alice in Wonderland! He showed us the most amazing little details on the leaves and trees which would normally have escaped my attention! Wonderful"
Penelope Malinga agreed "I will pay a lot more attention to the small details in future." Penelope also loved seeing Samango monkeys for the first time. A troop was feasting on the fresh green Celtis leaves right above our heads as we explored the forest edge.
We learnt so many fascinating facts like: Insects are the biggest herbivores and that woody plants (C3) utilise higher levels of carbon dioxide. Eugene demonstrated how to make rope from the bark of Dais cotonifolia (Grewia occidentalis also used for the is purpose), and we learned the vines of Dalbergia obovata are used to make fishing baskets.
Oriah and Kei Ellis, who are home schooled in Dargle, used the opportunity for some outdoor learning. "The tree ecology course was a great experience - learning about the different shapes of leaves, learning through the interactions with others, and how to simply identify trees. I also enjoyed taking a walk through Barend's forest, eating cookies and making new friends! " said Oriah afterwards.
Barend Booysen, who is custodian of the section of forest we spent time in, had a marvellous time. "I really thought I knew this forest backwards. I have been humbled by all the things I have never noticed before and my head is spinning with all the new information. I learnt so much. What a delightful man." David Crowe added "The two day workshop was informative and worthwhile."
Eugene Moll is a retired professor from the Department of Biodiversity and Conservation Biology at the University of the Western Cape. He holds a PhD in plant ecology from the University of KwaZulu-Natal. He edited the first edition of the Keith Coates Palgrave's Trees of Southern Africa, and has authored and co-authored many guides and papers on trees and the ecology of woody plants.
