Unmanned aerial systems for forest management

Airborne Light Detection and Ranging, called LiDAR, has used aircraft lasers to map large forested areas for over 30 years, but high costs and lack of color images have made it a less efficient resource for describing tree ...

Lifting the clouds on land clearing and biodiversity loss

QUT researchers have developed a new machine learning mathematical system that helps to identify and detect changes in biodiversity, including land clearing, when satellite imagery is obstructed by clouds.

Drought affects aspen survival decades later, new study finds

Drought—even in a single year—can leave aspen more vulnerable to insect infestation and other stressors decades later, a new study by NAU researchers found. Aspen trees that were not resilient to drought stayed smaller ...

Wild bees need deadwood in the forest

How many tree species are there in the forest? How are the trees scattered throughout? How high are the individual tree crowns? Are there fallen trees or hollowed-out tree trunks? Forest scientists characterize forests according ...
