Community structure, species-habitat relationship and conservation of amphibians in forested vernal pools in the Georgian Bay region of Ontario.
Forested vernal pools serve an integral role in the recruitment of amphibians in glaciated northeastern North America. In south-central Ontario, vernal pools exist in relatively unimpacted forest networks, but the amphibian communities face uncertain challenges from… Read More
Detection of potential vernal pools on the Canadian Shield (Ontario) using object-based image analysis in combination with machine learning
Vernal pools are small, temporary, forested wetlands of ecological importance with a high sensitivity to changing climate and land-use patterns. These ecosystems are under consider- able development pressure in southeastern Georgian Bay, where mapping techniques are required to… Read More
Use of fixed-wing and multi-rotor unmanned aerial vehicles to map dynamic changes in a freshwater marsh
We used a multi-rotor (Phantom 2 Vision+, DJI) and a fixed-wing (eBee, senseFly) unmanned aerial vehicle (UAV) to acquire high-spatial-resolution composite photos of an impounded freshwater marsh during late summer in 2014 and 2015. Dominant type and percent cover of three… Read More
Unmanned aerial vehicles produce high-resolution, seasonally-relevant imagery for classifying wetland vegetation
With recent advances in technology, personal aerial imagery acquired with unmanned aerial vehicles (UAVs) has transformed the way ecologists can map seasonal changes in wetland habitat. Here, we use a multi-rotor (consumer quad-copter, the DJI Phantom 2 Vision+) UAV to acquire a… Read More
