Plant Study Group in the Wolgan Valley
Plant Study Group - 2019

McMahons Lookout, Wentworth Falls - led by Jo Newman - 13 present
The 20 km drive along Kings Tableland Road gave us a great introduction to a varied and interesting 800 metre walk at the end of the road. It proved to be a comfortable temperature and the shady track covered two main plant groups - Tall Wet Forest and Woodland Ridge.
We were rewarded with magnificent views of Lake Burragorang and Coxs River with surrounding slopes of the beautiful Blue Mountains. The bush was refreshed by recent rains and plant sightings included Eucalyptus agglomerata, Eustrephus latifolius, Acacia elata and Rupicola sprengelioides (specific to McMahons Lookout) to name just a few.

Fairy Dell Reserve, Springwood – led by Susan Jalaluddin – 7 present
On a fine, cool morning 7 members met at Fairy Dell Reserve, Springwood to do a repeat survey of the silt plug. The first survey was done in July 2017 in the dead of winter by a group of citizen science volunteers and these data were passed on to the Blue Mountains City Council and the Fairy Dell Bushcare Group.
This latest survey was done in summer to ascertain any differences. The number of species found growing both in winter and summer was 45. From the winter survey, 23 species were seen and from the summer survey 37 species.
From the summer survey 10 new species were seen. There were what appeared to be some discrepancies but some of the reasons are:
- Much more time was available for our summer survey
- The observers for the summer survey were from the BMCS Plant Study Group and had more knowledge
- The +/- 5m accuracy of the plot may have included a slightly different area and hence species.
Those present had a wonderful time identifying and recording. We now have a slightly larger database to pass on to BMCC and the Bushcare Group and it will be interesting to do further surveys for comparison.

Radiata Plateau, Katoomba (Carpark to the Northern Dam) – led by Ray Stanford – 9 present
This part of the sandstone plateau is dominated by Eucalyptus sieberi
and Eucalyptus piperita
, especially on the higher section which also supports an understory of Hakea
and various herb species.
The lower section is an abrupt change including a creek which enters a man-made dam. This lower section includes Eucalyptus mannifera subsp. gullickii and many changes, for example, Grevillea laurina to Grevillea acanthifolia and Leptospermum trinervium to Leptospermum grandifolium, while the damp soil above the dam supports many species such as Gahnia sieberiana, Lepidosperma sp. and Drosera spatulata.
This 1 km track has a huge variety of plant species within two main communities.
