How drones can help your investment
Drone-based assessment: Using Unmanned Aerial Vehicles to achieve success for your project
Why use drones? The use of conventional monitoring techniques such as car-based transects is, in many situations, unadequate to assess the real risk situation a site may represent for bird and bat communities. The risk area is dependent on the type of project, and in vertical projects it is frequently above 50 m height, as per example in wind energy facilities.
How is it done? The drone is eqquiped with state of the art technology to capture signals of interest from the faunal groups to be assessed - birds, bats (or others). We use ultrasound detectors to detect bat activity, being able to measure its intensity and map its occurrence. Through the use of photographic or video cameras we can inspect remote locations and survey nests of species of conservation concern. Both aspects have a very relevant input for the project's viability and assessment robustness.
Drone-based surveys using ultrasound detectors enable us to monitor patterns of bat activity where the risk of impact is higher - close to the rotor swept area. Bats are killed mostly due to collision with wind turbine blades, therefore the use of conventional techniques may not be the best tool for risk assessment. Through the incorporation of reliable environmental variables into our assessments we can predict higher collision risk in certain timeframes evaluating with accuracy the viability of your project.
Bat monitoring at rotor height
The use of drones is the most efficient method to survey locations of difficult access - such as bird's nests of cliffs. We can also use drones to detemine the presence of less conspicuous species (hard to detect) which are important to assess the project's impacts.

Big fauna surveys
Fauna with large dimensions can easily be spotted and documented from an aerial point of view. Drone surveys are more cost-efficient than using aeroplanes and provide the same accuracy and reliability. We can help you gather information regarding the biodiversity values in your project's area and determine its viability.
Vegetation and habitat mapping
Our drone can be equipped with a high-resolution camera to efficiently map the vegetation and habitats present within the project's area. Using this methodology we can provide up-to-date land use and habitat mapping which is essential for an accurate assessment of the biodiversity values.
