The Treetec team were involved in one of the first studies to investigate the thermal properties of chainsaw carved introduced cavities compared to nest boxes and natural wildlife hollows.
The results showed that chainsaw carved introduced cavities are more thermally buffered from outside temperature fluctuations compared to nest boxes. This means that the carved hollows have a more stable microclimate that animals generally prefer. The introduced wildlife cavities are buffered against extreme high and extreme low daily temperatures occurring outside which is going to become even more important with climate change. The temperatures were very similar to those found in natural wildlife hollows.
