Park managers call for cost-effective and innovative solutions to handle a wide variety of environmental problems that threaten biodiversity in protected areas. Recently, drones have been called upon revolutionize conservation hold great potential evolve raise better-informed decisions assist management. Despite expectations, the benefits could bring foster effectiveness remain fundamentally unexplored. To address this gap, we performed literature review about use conservation. We selected total 256 studies, which 99 were carried out classified studies five distinct areas applications: “wildlife monitoring management”; “ecosystem monitoring”; “law enforcement”; “ecotourism”; “environmental management disaster response”. also identified specific gaps challenges would allow expansion critical research or monitoring. Our results support evidence merits serve actions reinforce effective management, but multidisciplinary must resolve operational analytical shortcomings undermine prospects integration

Mapping and Classification of Ecologically Sensitive Marine Habitats Using Unmanned Aerial Vehicle (UAV) Imagery and Object-Based Image Analysis (OBIA)

Remote Sensing, Journal Year: 2018, Volume and Issue: 10(9), P. 1331 - 1331

Published: Aug. 21, 2018

Nowadays, emerging technologies, such as long-range transmitters, increasingly miniaturized components for positioning, and enhanced imaging sensors, have led to an upsurge in the availability of new ecological applications remote sensing based on unmanned aerial vehicles (UAVs), sometimes referred “drones”. In fact, structure-from-motion (SfM) photogrammetry coupled with imagery acquired by UAVs offers a rapid inexpensive tool produce high-resolution orthomosaics, giving ecologists way responsive, timely, cost-effective monitoring processes. Here, we adopted lightweight quadcopter survey object-based image analysis (OBIA) workflow demonstrate strength methods producing very high spatial resolution maps sensitive marine habitats. Therefore, three different coastal environments were mapped using autonomous flight capability UAV equipped fully stabilized consumer-grade RGB digital camera. particular investigated Posidonia oceanica seagrass meadow, rocky coast nurseries juvenile fish, two sandy areas showing biogenic reefs Sabelleria alveolata. We adopted, first time, UAV-based raster thematic these key habitats, produced after OBIA classification, method fine-scale, low-cost, time saving characterization which may lead more effective efficient management natural resources.

Location, location, location: considerations when using lightweight drones in challenging environments

Remote Sensing in Ecology and Conservation, Journal Year: 2017, Volume and Issue: 4(1), P. 7 - 19

Published: Aug. 22, 2017

Abstract Lightweight drones have emerged recently as a remote sensing survey tool of choice for ecologists, conservation practitioners and environmental scientists. In published work, there are plentiful details on the parameters settings used successful data capture, but in contrast is dearth information describing operational complexity drone deployment. Information about practices flying field, whilst currently lacking, would be useful others embarking new drone‐based investigations. As group drone‐piloting scientists, we operated lightweight research over 25 projects, 10 countries, polar, desert, coastal tropical ecosystems, with many hundreds hours experience between us. The purpose this paper was to document lesser‐reported methodological pitfalls deployments so that other scientists can understand spectrum considerations need accounted prior to, during flights. Herein, describe most common challenges encountered, alongside mitigation remediation actions increase chances safe capture. Challenges grouped into following categories: (i) pre‐flight planning, (ii) flight operations, (iii) weather, (iv) redundancy, (v) quality, (vi) batteries. We also discuss importance undertaking ethical assessment their practices, identify mitigate potential conflicts associated use particular areas. By sharing our experience, intention will assist those deployments, increasing efficacy acquiring high‐quality from proximal aerial viewpoint.

Principles and practice of acquiring drone-based image data in marine environments

Marine and Freshwater Research, Journal Year: 2018, Volume and Issue: 70(7), P. 952 - 952

Published: July 12, 2018

With almost limitless applications across marine and freshwater environments, the number of people using, wanting to use, remotely piloted aircraft systems (or drones) is increasing exponentially. However, successfully using drones for data collection mapping often preceded by hours researching drone capabilities functionality followed numerous limited-success flights as users tailor their approach through trial error. Working over water can be particularly complex published research rarely documents methodology practical information in sufficient detail allow others, with little remote pilot experience, replicate them or learn from mistakes. This frustrating expensive, when working locations where window access small. The aim this paper provide a guide drone-based acquisition considerations. We hope minimise amount error required obtain high-quality, map-ready outlining principles practice drones, environments. Importantly, our recommendations are grounded sensing photogrammetry theory so that collected appropriate making measurements conducting quantitative analysis.
