In 2013 and 2014 a team of researches attempted to apply for EU LIFE+ funding for a project studying dead wood restoration in natural and urban landscapes. Even though we failed both times, the LIGNEUS project team built a very good network of similarly minded experts.
Here is one study I have received today through one of the LIGNEUS partners
Tanhuanpää, T. Kankare, V. Vastaranta, M Saarinen, N. Holopainen, M. 2015. Monitoring downed coarse wood debris through appearance of canopy gaps in urban boreal forests with bitemporal ALS data. Urban Forestry & Urban Greening 14: 835-843.
