ENDANGERED
The threatened species history of
Bossiaea scortechinii.
In 2002, Clarence Environment Centre amateur botanists John and Patricia Edwards
collected a specimen from a small shrub of the
Bossiaea
family that they found
growing on a section of Crown road reserve. This land was later acquired by North
Coast Water (NCW) as a part of their land purchase for the Shannon Creek dam.
Examination of the specimen by the Edwards'
suggested the shrub was
B. scortechinii
, but their
confidence was tested when their reference,
“Flora of New South Wales", claimed the species
grew on the NSW tablelands and had not
previously been recorded from the North Coast
botanic region.
To confirm the identity of the plant, specimens
were forwarded to herbaria at Coffs Harbour and the Sydney Botanic Gardens, where
both institutions confirmed the plant was indeed
B. scortechinii.
However, the
Sydney Botanic Gardens congratulated the find, claiming the collection to be only
the second from the North Coast biological region.
In 2005 the Edwards' checked the impacts of the
proposed access road route to the dam site, and
identified an area of very high conservation value,
containing a large population of an endangered
shrub,
Boronia hapalophylla.
The
Boronia
was a
new species, which they had discovered, co-
described, and successfully nominated as an
endangered species two years earlier. At the same
spot, a small group of the rare
Bossiaea
was also
found, along with another rare species,
Tephrosia
filipes.
Briefly,
Tephrosia filipes
is known to occur in only five
scattered populations in NSW, all within a small area
between Copmanhurst and Dalmorton in the Clarence
Valley.
Boronia hapalophylla
is known to occur only in the
Shannon Creek area.
Given the imminent destruction of the area to build the access road, the Edwards'
nominated the
Bossiaea
as an endangered population, and
Tephrosia filipes
as an
endangered species.
