A closer look at Brogo

Two years on from the Black Summer, bushfire recovery funding is allowing us to survey for threatened species on Brogo Reserve for the first time.

On New Year’s Eve 2019, the fast-moving Badja bushfire came within kilometres of Brogo Reserve, Yuin country in the Bega Valley of New South Wales. A sudden wind change saved Brogo and its neighbours, but the surrounding region was decimated; the fire burnt through over 315,000 hectares, destroying 422 homes and much habitat.

In the weeks and months that followed, we expect that Brogo became a refuge for birds and other animals that managed to escape the flames.

First purchased in 1995, Brogo was one of Bush Heritage’s earliest mainland acquisitions.

At 120 hectares, it is a small but significant reserve, protecting what is likely the largest remaining patch of the Brogo Wet Vine Forest threatened ecological community in existence.

With steep slopes, dry ridgelines, deep gullies, large granite outcrops, pockets of temperate rainforest and even a couple of hundred metres of frontage onto the Brogo River, many diverse habitat types are found here making the reserve capable of supporting a huge variety of species.

However, while comprehensive surveys had been carried out on Brogo in the past, none have been undertaken in recent years. Now, thanks to bushfire recovery funding from the Department of Agriculture, Water and the Environment, we’re taking a closer look at Brogo’s inhabitants.

This Spring, Brogo Reserve Project Officer Josh Wellington was joined by local contract ecologists Sam Patmore and Vanessa Place to conduct fauna surveys on Brogo with a focus on identifying threatened species.

Over three trips in September, October and November, the team used a range of different survey methods:

  • ground-based remote sensing cameras for terrestrial (ground-dwelling) mammals such as quolls,
  • tree-top cameras for arboreal (tree-dwelling) mammals such as possums and gliders,
  • call playback and spotlighting for forest owls,
  • acoustic monitoring for bats, and
  • diurnal (daytime) bird surveys.

So far, with only preliminary results in, they've detected several threatened species, all of which are vulnerable in New South Wales:

  • Gang-gang Cockatoos (Callocephalon fimbriatum),
  • a Powerful Owl (Ninox strenua),
  • Varied Sittellas (Daphoenositta chrysoptera),
  • Dusky Woodswallows (Artamus cyanopterus), and
  • two threatened bats – the Large Bent-winged Bat (Miniopterus orianae oceanensis) and the Eastern Coastal Free-tailed Bat (Micronomus norfolkensis).

This, on top of many other non-threatened species including wombats, Brush-tailed and Ring-tailed possums, Sugar Gliders, and a series of bush rats and antechinus.

The data from these surveys will allow us to better target our management so these species are looked after for the long-term.

At the moment, Josh’s days are filled with weed control and feral animal management, focusing on deer, foxes and rabbits. There are also plans to begin cultural burns in the new year, and to deepen our relationship and engagement with local Yuin people.

It’s now two years on from the bushfires and Josh says the burn areas are recovering well, helped along by good rains. Hopefully, that means native species aren’t having to rely on the reserve quite as much as they may have done in the immediate aftermath of the blaze. But if ever again they need a refuge, Brogo will be there, protected forever.
