Development of a UAV-LiDAR System with Application to Forest Inventory
Remote Sensing, 2012 We present the development of a low-cost Unmanned Aerial Vehicle-Light Detecting and Ranging (UAV-LiDAR) system and an accompanying workflow to produce 3D point clouds. UAV systems provide an unrivalled combination of high temporal and spatial resolution

Impact of forestry practices on fitness correlates and population productivity in an open-nesting bird species [PDF]
, 2007 In the boreal forests of Fennoscandia, over 99% of the forest area has been altered by forestry practices, which has created forests of differing age structures and stand characteristics than primary forest stands.

Understanding the evolution of native pinewoods in Scotland will benefit their future management and conservation [PDF]
, 2010 Scots pine (Pinus sylvestris L.) is a foundation species in Scottish highland forests and a national icon. Due to heavy exploitation, the current native pinewood coverage represents a small fraction of the postglacial maximum.

Forest Canopy Height Estimation Using Tandem-X Coherence Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016 In this paper, we report results of a study aimed at assessing the potential for using X-band single-pass radar interferometric coherence for forest canopy height estimation. We use datasets from the Tandem-X satellite pair collected over Canadian forest

The Impacts of Calamity Logging on the Development of Spruce Wood Prices in Czech Forestry
Forests, 2020 Currently, the decline in spruce wood prices is a serious problem for the forestry sector in the Czech Republic. We estimate that the fall in wood prices in European markets causes losses not only to the forestry companies producing, harvesting, and ...
