60 Diels’ Photographic Sites - 82 years later A study of Resilience in southwestern Australia Byron B. Lamont and Brian J. Grieve

Western Australia. Appendix D
In 1900-02, Drs L. Diels and E. Pritzel travelled extensively in southwestern Australia. The outcome was the classic work, Diels, L 906. Die Pflanzenwelt von West-Australien. In the process of translat- ing and updating this text, we have tried to relocate and rephotograph the sites of the plates in this mammoth book. Below are paired photos from 12 selected sites in Diels, taken 82 years apart. POSTER PREPARED FOR MEDECOS 98 6 Eradu, 46km E of Geraldton Little change. Same mallee (Eucalyptus eusdesmoides) present, ‘grass’ (Ecdeioco- lea monostachya) thinned out, Acacia rostellifera (dead in foreground) established and died during that time. 6 Mt Elphin-stone, Albany Site almost unchanged. Ground cover of Lepidosperma aff. effusum now almost completely replaced by Stypandra imbricata and annual grasses.
6 Mouth of Denmark River Original two karri trees blown over at a height of 39m by cyclone Alby, Jan. 1978; present stand up to 16m high, fringing vegetation now denser; Watsonia (South Africa) common along edge. 6 Newcastle (Toodyay) Almost unchanged, except bare ground replaced by a wide range of annual weeds. 6 Leschenault Inlet, Bunbury Only mangroves Avicennia marina left on S side of inlet are pictured in foreground; many mangroves on N side fallen over; in background, piles of woodchips, bauxite and harbour; retaining wall in foreground built about 96. 66 Serpentine Grasstrees thinned considerably (human use); Banksia grandis replaced by Euca- lyptus calophylla, new ground cover (Leptocarpus, Hakea sulcata, Lepidospermum ellipticum) suggests site now wetter. 67 Sukey Hill, 5km E of Cranbrook Little change except emergent mallee (E. tetragona) not found, Dryandra armata (erect dark branches in Diels) is very short, although no evidence of recent fire.
68 White Peak, 10km N Geraldton
Most of the surrounding area cleared for farming; veg- etation now denser on peak; wild oats in valley; high species rich- ness retained however Melaleuca gomphocephala replaced by more drought-tolerent species; peak fenced in October 1983, to protect rare species of Drummondita. 69 Lockier River, Mingenew Watercourses severely degraded as indirect result of widespread clearing for agri- culture in 90s; most trees and shrubs eliminated; slopes densely covered with annual weeds; a few native halophytes now present (increased salinity). 70 Meenaar Travelled 40km around Meenaar without finding a thicket of Melaleuca uncinata beneath salmon gums (E. salmonophloia) as this provides the best farmland; pic- tured is the closest remnant of salmon gum vegetation to Meenaar. 7 Meenaar Almost no change. Fallen York gum (E. loxophleba) may have been in original photo; minor annual weed invasion
7 Southern Cross Little change. Individual plants seem to have denser foliage; salt bushes (Atriplex, Maireana) now widespread as a ground cover (saltier, less grazing?); some weeds.
7 CONCLUSIONS Southwestern Australia has undergone massive human interference during the last 80 years. The level of direct interference has had greatest impact on structure of the vegetation and extent of invasion by annual weeds, while indirect interfer- ence (increased salinity, low or higher water availability) appears to have had most impact on floristics of the dominants. Some floristic changes suggest a reduction in effective rainfall may have occurred during that time. Unlike Diels, none of his revisited sites showed evidence of recent fire.
