ECOtas undertakes a number of self-funded research projects and collaborates with other organisations such as the Forest Practices Authority, University of Tasmania, Tasmanian Herbarium, the Threatened Species Section (DPIPWE), and even international universities.
The main focus of our research is the ecology, distribution, habitat characteristics and conservation management requirements of threatened plant species, and the potential impacts of forestry practices on conservation values (especially hollow-dependent fauna). Mark’s life-long interest in Tasmanian native orchids is reflected in a number of research directions.
Some examples of our research projects are described below. Please contact Mark Wapstra if you want to know more about any of these (or other) projects.
Distribution, habitat characteristics and conservation status of the purple rushlily Sowerbaea juncea (Laxmanniaceae) in Tasmania
This was an ECOtas funded project undertaken by Mark Wapstra. Sowerbaea juncea is known from southeastern Australia but in Tasmania until 2006 was represented by less than 5 collections, all from the Ansons Bay-Gladstone area in the northeast. The species was listed as rare on the Tasmanian Threatened Species Protection Act 1995 at the start of the project but has since been uplisted to vulnerable. ECOtas examined herbarium collections and database information, undertook extension surveys and compiled information on the ecology of the species. We found the species in several more locations (mainly on private land), that it can be locally plentiful and that it may tolerate quite high levels of disturbance (e.g. from cattle grazing and fire). However, the extensive historical land clearing in northeastern Tasmania, especially in the near-coastal zone, has probably led to a drastic decline in the range of the species.
As with many of our threatened plants, unmanaged reservation may not be the key to maintaining viable populations. Sowerbaea juncea appears to be favoured by relatively high levels of disturbance such as cattle grazing and low intensity burning, which seems to provide the ideal open habitat.
The results of this work were published in the Tasmanian Museum & Art Gallery’s scientific journal, Kanunnah.

Classification and ecology of Tasmanian Senecio (Asteraceae): native fireweeds and groundsels
The genus Senecio has recently been subject to a major taxonomic overhaul, which resulted in an almost doubling of the number of recognised taxa. Several are listed as threatened already and some of the “new” species may qualify for listing (this has already occured for S. georgianus and S. psilocarpus). In trying to get a handle on the group, I became fascinated by them and a key for Tasmanian species was constructed (see citation below).
I am happy to receive specimens of Senecio from environmental consultants, naturalists and other professionals for identification. This is a free plant identification service (for Senecio only) and will include note-form written confirmation of identifications and appropriate curation of specimens for submission to the Tasmanian Herbarium (where appropriate).
Note that successful identification of some species requires carefully collected specimens that includes the root system (for the disciform species i.e. those without the typical “daisy” flowerhead), and the lower to middle portion of the stem and leaves (and obviously flowers). Sometimes a collection of several specimens from the one site is useful for identification purposes.
Fresh specimens can be wrapped in moist (not wet) paper towel and/or moss and refrigerated for several days to maintain freshness of radiate flowerheads (i.e. the showy “daisy” type) and shape of leaves. If prompt identification cannot be undertaken, light pressing in newspaper (with larger flowers and fleshier leaves wrapped gently in additional paper towel) will usually result in specimens that can be easily identified. Any collected material should be accompanied by the following minimum information: height of specimen(s), location (13-figure grid reference with datum noted and/or latitude/longitude), site name, collection date, habitat information (e.g. vegetation type, altitude, geology, disturbance history) and who collected the specimen.

Distribution, habitat characteristics, ecology and conservation management requirements of Thismia rodwayi (fairy lanterns) in Tasmania
Thismia rodwayi is perhaps one of Tasmania’s most fascinating plants. It is aptly named the ‘fairy lanterns’ because of its bright orange-red colour and unique flower structure.
My fascination with this beautiful little plant began in late 2002 while still working at the Forest Practices Authority, when the species was inadvertently discovered in a forestry coupe proposed for selective logging. This began a series of surveys for the species round the State, culminating in a report and a scientific paper. My fascination with the species has continued and I am interested in hearing from anybody who may have information on the species.
ECOtas is available to undertake formal surveys for this species for proposed forestry operations, commercial developments and other activities (consultancies undertaken for this species will be undertaken at a 20% discount on my current rates, on the understanding that site data (positive and negative) can be used for personal research).
