Vulkathunha Gammon Ranges Project

This is a long-term ecological monitoring project in the Arcoona Creek catchment area of the Vulkathunha-Gammon Ranges National Park. Begun in 1988 with the installation of a rain gauge on the Gammon Plateau, the program has expanded to include:

  • Continuous rainfall records at high and low elevations (9 pluviometers)
  • Stream flow recording
  • Photographic botanical monitoring
  • Human impact monitoring
  • Native and Feral animal counts

At times it has also served as a backbone for other projects, including Yellow-footed Rock Wallaby monitoring, fox baiting, short term but more intensive animal and plant surveys, minor paleontological work, observations of a lizard reputed to be locally extinct, and introduction of students to remote area field-work.

VGRaSP Expedition Timetable

Each year we do two main trips, one in Autumn and one in Spring.
The trips include a routine check of data loggers, batteries, pluviometers and taking vegetation photos at regular photo points.Trips may also involve maintenance, upgrade or installation work at various sites.

Autumn Trip (April)

Usually coincides with the Anzac Day Long Weekend (and/or easter if they are close together)

Spring Trip (October)

Usually coincides with the Labour Day Long Weekend

Usually there is a group get-together (6 to 12 people) about 3 weeks before the start of the trip.As you might imagine, with several groups of people doing various jobs in different places, logistics needs a bit of care. Transport, timetabling, sharing tools and equipment, meeting places and times, all need to be planned.

Expeditioners need to be able to carry a pack with some equipment, plus tent, sleeping bag, stove, food, etc 8 kilometres along a creek to our camp. We stay there for two nights, doing jobs near camp, on our way to and on ‘The Plateau’.
