Researchers have found a large variety of plant and animal species in the Little Desert National Park and surrounding areas - including some that might be new species.
The team of 30 researchers - including experts from Museums Victoria, Royal Botanic Gardens Melbourne, Queensland Museum and the University of New South Wales - have spent the past two weeks in the region as part of a Bush Blitz expedition.
Bush Blitz manager Jo Harding said the undertaking had an educational aspect as well as being about environmental conservation.
"On the Wimmera region Bush Blitz we were also lucky enough to have five teachers involved as part of Bush Blitz TeachLive," she said, "One teacher is from Good Shepherd College in Hamilton and her students often visit the Little Desert National Park".
The teachers worked alongside researchers in the field and field lab while they communicated with their classes about their findings through blogs and Skype.
Off-site teachers were also able to follow the expedition remotely, as well as have a live question-and-answer session with scientists.
The spider team were very successful, finding a diverse array of eight-legged specimens from large wolf spiders to tiny peacock spiders, while the entomologists recorded hundreds of different species of leaf bugs, weevils, millipedes, native cockroaches, dragonflies and moths.
A statement from Bush Blitz said experts are confident they will confirm new species among the findings after they have had a chance to study them further.
The botanical team discovered 25 different species of orchid in the Tallageira State Forest and the only population of native currant known in Victoria at Forrester Springs.
There were a number of reptile sightings including a rare spotting of the Rosenberg's goanna, which was only found to occur in Victoria in 1983 and is listed as endangered.
Bush Blitz field manager Dr Kate Grarock said community outreach was an important part of the program, with a Discovery Day in Nhill engaging adults and children to learn about species discovery and conservation.
There are an estimated 580,000 to 680,000 species in Australia, but three-quarters of this biodiversity is yet to be identified.
About 45 per cent of continental Australia and over 90 per cent of Australia's marine area have never been comprehensively surveyed by scientists.
Dr Grarock said the program, which receives federal government funding, has run more than 40 expeditions in areas around Australia that are usually underrepresented by wildlife surveys.
"If we don't even know what we have, we can't protect it. Naming a species is the first part of protecting it," she said.
