2022 Bioblitz Report

Volunteers spent the day and night On Saturday February 5th using a range of techniques to see what living things could be found. From the day a whopping 428 observations were added to the Tarra-Bulga National Park project on the citizen science website www.iNaturalist.org. A number of plant and fungi species were recorded, but the vast majority of records were for an amazing array of insects and other invertebrates. Many finds that were uploaded to the website are still to be identified but so far, we can confirm that we have recorded at least 215 different species for the day, roughly 60 of them had never previously been recorded at Tarra-Bulga.  

The day’s focus was mainly on invertebrates, other planned activities for the year aim to add to the flora and fauna records for the park, these include a fungi foray in May, a mid-winter walk looking at ferns and mosses, and a plant identification day as well as bird survey in spring. As well as these activities, Friends of Tarra-Bulga hold regular working bees and are always on the lookout for people interested in joining our crew of volunteers that staff the park Visitor Centre.

Tarra-Bulga Bioblitz

It’s not too late to sign up for our Bio-blitz. This Saturday (February 5th) Where we will aim to record as many species of any lifeform (Insects, Birds, Plants, Fungi etc) we can find on the day. We will use the Citizen Science Website/App iNaturalist https://inaturalist.ala.org.au/ to log our findings. Conveniently the site already has a Tarra-Bulga National Park project set up that automatically records any sightings made within the Park. https://inaturalist.ala.org.au/…/tarra-bulga-national-park

As you can see it is well established already with 5.350 observations and 1,170 species recorded. We will aim to use a number of survey techniques to find as many species as possible. I think 200 species would be a good result for the day.

Anyway if you would like to join in we will kick off at 10am but you are welcome to come and go at any time. If the weather is suitable we will put up a light sheet in the evening which should attract a lot of night flying insect species. Registration is via ParkConnect https://www.parkconnect.vic.gov.au/Volunteer/public-planned-activity/?id=6768c4d9-446c-ec11-b820-0003ff6f999a

With iNaturalist you can download the App and upload sightings directly from a phone or you can upload any photos you take on a camera when you get back home and upload them via the website later on. If you don’t want to log your own sightings feel free to just come along and observe.

Do bring food for the day, as well as any cameras, binoculars etc that you would like to use. Contact 0488 035 314 for further information.
