Book chapters in press

Following a visit to the US last year and meeting Chad Hanson and Dominick Dellasala as part of a study into the use of ecological knowledge in fire management, I was invited to contribute chapters to their recent book on the Ecological importance of mixed severity fires. The book is expected to be published in June 2015.

Paper in press – Predicting the occurrence of fire refuges

Berry, L.E., Driscoll, D.A., Stein, J.A., Blanchard, W., Banks, S.C., Bradstock, R.A. and Lindenmayer, D. B., 2015, Identifying the location of fire refuges in wet forest ecosystems, Ecological Applications


The increasing frequency of large, high-severity fires threatens the survival of old-growth specialist fauna in fire-prone forests. Within topographically diverse montane forests, areas which experience less severe or fewer fires compared with those prevailing in the landscape may present unique resource opportunities enabling old-growth specialist fauna to survive. Statistical landscape models which identify the extent and distribution of potential fire refuges may assist land managers to incorporate these areas into relevant biodiversity conservation strategies.

We used a case study in an Australian wet montane forest to establish how predictive fire simulation models can be interpreted as management tools to identify potential fire refuges. We examined the relationship between the probability of fire refuge occurrence as predicted by an existing fire refuge model and fire severity experienced during a large wildfire. We also examined the extent to which local fire severity was influenced by fire severity in the surrounding landscape. We used a combination of statistical approaches including generalised linear modelling, variogram analysis and receiver operating characteristics and area under the curve analysis (ROC AUC).

We found that the amount of unburnt habitat and the factors influencing the retention and location of fire refuges varied with fire conditions. Under extreme fire conditions, the distribution of fire refuges was limited to only extremely sheltered, fire-resistant regions of the landscape. During extreme fire conditions, fire severity patterns were largely determined by stochastic factors that could not be predicted by the model. When fire conditions were moderate, physical landscape properties appeared to mediate fire severity distribution.

Our study demonstrates that land managers can employ predictive landscape fire models to identify the broader climatic and spatial domain within which fire refuges are likely to be present. It is essential that within these envelopes, forest is protected from logging, roads and other developments so that the ecological processes related to the establishment and subsequent use of fire refuges are maintained.

Publication – Bird response to the size and isolation of unburnt residuals

Berry, L. E., Lindenmayer, D. B., & Driscoll, D. A. (2014). Large unburnt areas, not small unburnt patches are needed to conserve avian diversity in fire‐prone landscapes. Journal of Applied Ecology.


1. Mitigating the impacts of large-scale fires on biodiversity is becoming increasingly important as their frequency increases. In response, fire managers have engaged with the concept that retaining small unburnt residual areas of vegetation within extensively burnt landscapes may facilitate biodiversity conservation. However, it remains uncertain how the size and isolation of these unburnt residuals influence faunal distributions, persistence and recovery following fire.

2. We used a replicated observation study to test bird responses to the size and isolation of unburnt residuals in a Mallee woodland area recently burnt by a 28,000-ha wildfire in southern Australia. The scale of our study provided a rare opportunity to consider the responses of large mobile organisms to fire-induced habitat fragmentation. Within five replicated spatial blocks, we crossed two levels of isolation with large (5–7ha) and small (1–3ha) unburnt patches and matrix sites burnt five years previously. We compared these site types to six continuous (non-fragmented) unburnt sites. We surveyed each site on eight occasions.

3. Most birds occurred more frequently in unburnt habitat beyond the extent of the fire. Bird responses to the availability and spatial distribution of unburnt remnants within the fire were largely influenced by their ability to use the recently burnt matrix. Occurrence of five species was higher in unburnt residuals when more of the landscape within 500 m was burnt.

4. A fire refuge effect may be likely for two competitive species that occurred more frequently in unburnt residuals than in the burnt matrix or continuous unburnt habitat. For the weebill, re-colonisation following fire was likely to occur gradually over-time from ex-situ sources.

5. Synthesis and applications. To maintain avian diversity in fire-prone landscapes, our results suggest a need to shift management focus from creating networks of small unburnt patches, towards preserving large, intact areas of habitat. However, five species common to the burnt matrix preferentially selected residual patches when unburnt resources were locally scarce. Therefore, to benefit birds, land managers should limit the extent of applied burns and use narrow burns. When planning large burns, practitioners should consider that a number of species will remain absent from the landscape for several decades.

Publication – Marsupial occurrence in potential fire refuges

Berry, L., Driscoll, D., Banks, S., & Lindenmayer, D. (2014). The use of topographic fire refuges by the greater glider, Petauroides volans and the mountain brushtail possum, Trichosurus cunninghami following a landscape-scale fire. Australian Mammalogy.


We examined the potential conservation value of topographic fire refuges for arboreal marsupials in a stand-replacing crown-fire forest ecosystem. We surveyed arboreal marsupial abundance across 48 sites in rainforest gullies burnt to differing extents by the 2009 fires in the Mountain Ash (Eucalyptus regnans) forests of the Victorian Central Highlands, Australia. The greater glider (Petauroides volans) was significantly less abundant within the extent of the 2009 fire. The mountain brushtail possum (Trichosurus cunninghami) appeared to be more abundant within the extent of the 2009 fire and was particularly abundant within unburnt peninsulas protruding into burnt areas from unburnt edges. Our results indicate that while fire refuges are potentially important outcomes of large fires for some species; further research is required to address the mechanisms underpinning these response patterns.

Volunteer blogs

As part of their undergraduate studies at the Fenner School, two of our volunteers have written short blogs about their experiences working with us in the field earlier this year. Our study greatly benefited from the help of these two enthusiastic and passionate students. It is great to see how their experiences in these forests have influenced their thinking on some of the key conservation issues facing the region.

Radio Interview

During our recent field season, we were visted by ABC Radio National’s Ann Jones, who documented our work on the mountain brushtail possum for her show Off Track. The programme is excellently put together and gives a great insight into our work on the species and the Central Highlands long term research study in general.
