There is a quite strenuous walk along the Tarn Shelf, over Newdegate Pass & back along the Rodway Range. Students that are not physically fit must seek the advice of the unit coordinator. This part of the course is based at the Giant’s Table, Maydena. The second part of the course introduces demographic techniques, conservation strategies & practice, & examines applied ecological practice in forestry harvesting methods in wet sclerophyll forest in the long-term monitoring site at Warra as day excursions from the Sandy Bay campus. Assessment is by: a field test (50%) on the last day of the course, assessing plant identification ability & an understanding of the ecological processes shaping the vegetation; two reports based on data collected in the field (40%); & a group plant collection (10%). Transport Transport to Mt Field from the University is provided. Vehicles will depart from the Life Sciences car park at 9:00 am Mon. 8th Feb. & return at 5:00 pm on Fri. 12th Feb. Please bring your lunch, waterproofs & collecting gear packed separately for Day 1. Equipment 1. Adequate clothing is essential; warm clothes, good boots & waterproof clothing are required for protection against rain, wind & snow. The weather at Mt Field can be very changeable & work will proceed regardless of weather. Swimming is possible in good weather, so bring bathers. Also bring spare footwear & clothing for evening wear. Bring a light daypack for day trips 2. You will be working at 1000 metres, so bring a sunscreen (15 +), insect repellant & a shade hat. 3. Bring personal collecting equipment, field note books, masking tape, zip-lock plastic bags, hand lens, camera, clipboard & texts. Accommodation & Costs Accommodation is luxurious this year, but you will need to bring your own fluffy dressing gown, slippers, & towel. There is a levy of $120 to help cover accommodation costs, the School will fund the remainder. This should be paid prior to the course at the Cashiers Office (Admin. Building), quoting account no. 1.10.319.44787.3807. Alternatively, you may find your own accommodation but this would diminish the experience. If you have difficulty in paying the levy, please discuss the matter with Dr Anthony Koutoulis. Cooking Dinner is supplied on all four nights. Bring food for breakfast & lunches, although milk & bread, tea & coffee will be provided. Be prepared to take lunches & drinks into the field. Collections Only small samples of plant specimens may be taken in the National Park, & samples are not to be taken next to or alongside walking tracks. Alternatively, photographic collections may be made.

KPA375 Field Botany - Mt Field Handbook 4 OUTLINE OF ACTIVITIES PART 1. PLANT COMMUNITIES OF MT FIELD & SOUTHWEST TASMANIA An outline of the week's activities at Mt Field follows, although the weather will dictate to some extent what can be achieved, & in what order. Day 1: Altitudinal transect & associated changes in physiognomy & community types • Examination of sub-alpine sclerophyll woodland, moor, mixed forest & wet sclerophyll communities & the basis of community classifications. • Species recognition, species identification, plant collection. • Altitudinal variation in plant communities & its causes. Day 2: Alpine vegetation (Tarn Shelf, Newdegate Pass, Rodway Range) • Examination of communities including: herbfields, microshrubbery (cushionplants), coniferous shrubbery, alpine rainforest. • Species recognition, species identification, plant collection. • Community identification in relation to microenvironment. • Growth habit & general morphology of microshrubbery. • Effect of fire on alpine vegetation. Day 3: East-West variation in vegetation • Illustration of the association of vegetation types with geology & soils, • Study of rainforest & buttongrass communities, plant collection. • The nature of boundaries between vegetation types. Day 4: Succession in wet sclerophyll forest & the impact of forestry practices • Temporal changes in vegetation type & physiognomy following disturbance by fire / clearfelling from year zero to 400 years. • Ecological basis of silvicultural practices in wet sclerophyll vegetation. Day 5: Bryological diversity & mophological variation in eucalypts - patterns & processes. • Identification of moss & hepatic species & ecological preferences at Growling Swallet • Morphological changes in the E. vernicosa complex on Tim Shea/Mt Field with altitude & exposure. • Inter- & intra-specific variation in E. nitida & E. coccifera on Tim Shea. KPA375 Field Botany - Mt Field Handbook 5 OUTLINE OF ACTIVITIES PART 2. APPLIED FIELD BOTANY Day 6: Population ecology & conservation of endangered species • Long term monitoring project for seedling establishment for the rare & endangered Eucalyptus morrisbyi at Calverts Hill. • Data entry Day 7: Long term ecological monitoring site at Warra • Variable retention silviculture in Tasmania – alternatives
