267 + 10 This population was assessed 1/10/09. 267 plants tagged.
Plants regenerating from fire, old burnt fruits only no new
buds/flowers/fruits. Ran out of tags. More plants to the NE
and SW of tagged population estimated additional 10 plants.

92 + 200 This population was visited on 30/9/09 & 2/10/09. 50 plants
tagged, another 42 plants marked with blue flagging tape
along roadside within 25m proposed disturbance area. These
plants are assumed to be potentially under threat during road
works. This population is a mixture of E.burdettiana &
E.coronata. Lots more plants seen and yet to be tagged.
Vegetation very thick, last burnt 1989. (6/10/09)

188 + 300
316 + 1500
This population was not revisited during this survey as it was
concluded that to visit and mark every plant was not effective.
Estimates of additional plants made using aerial photography
is 200
This population was initially visited on 1/10/09. 42 plants
tagged, ran out of light. Population extends further up ridge
from tagged plants (6/10/09).
This population was revisited 21/10/09 and found to extend
upslope and into gully/plateau below sheer cliff of the summit.
Nearer the top this species begins to mix with E.coronata.
The vegetation was last burnt in 1989 and was too thick to do
a thorough survey so plants counted is 188 but estimated
number of plants is 300 (30/10/09).
This population also extended from where the plants were
recorded on the 1/10/09 to the west along the NW face of
East Mt Barren and extends from just below summit
downslope almost to bottom. The extent and no. of plants
was assessed on 24/10/09, 316 plants were marked but a lot
more were seen (too many to count individually). The
estimated number of plants is 1200
