Terrestrial lidars are being utilized for ecological assessment of an expanding range of ecosystems. As well as providing independent estimates of ecological parameters, these lidars are increasingly synthesized with satellite and airborne observations, providing valuable validation and augmentation information. Logistics and the cost of instruments are the main limiting factors to expanded deployment. Ecological assessment is therefore particularly restricted in ecosystems with difficult or hazardous terrain, such as dense tropical forests and mountainous areas. Tidal inundation in coastal systems such as saltmarshes and mangroves pose a risk to equipment, as well limiting the available time to acquire terrestrial lidar data, a challenge for instruments with longer scan durations. In addition, access to ecosystems is often most limited during episodic events (such as storms) and periods of temporal dynamism. Therefore, terrestrial lidar instruments optimized for portability, durability and scanning speed can be used to overcome these deployment challenges and provide the opportunity to acquire high resolution data in important ecosystems. The Canopy Biomass LiDAR (CBL) is an inexpensive, highly portable, fast-scanning, time-of-flight, terrestrial laser scanning (TLS) instrument, developed and refined in a collaboration between the University of Massachusetts Boston and the Rochester Institute of Technology (RIT). This instrument has been successfully deployed in structured sampling efforts in temperate and tropical forests, mangroves, and saltmarshes. Synthesis and validation efforts are underway with observations from MODIS, LandSat 8, G-LiHT and EcoSAR resources, and independent estimates of biomass for forest, mangrove and saltmarsh vegetation, utilizing a variety of reconstruction techniques,are being explored. Deployment, processing, and reconstruction approaches will be presented, alongside preliminary results from deployments of the CBL across a range of ecosystems.
