10 Top Conservation Tech Innovations From 2017
By Sue Palminteri
Technology is changing how we investigate and protect planet Earth.
The increased portability and reduced cost of data collection and synthesis tools, for instance—from visual and acoustic sensors to DNA sequencers, online mapping platforms and apps for sharing photos—have rapidly transformed how we research and conserve the natural world.
These tools afford research and conservation projects across the globe an unprecedented capacity to access, collect, organize, analyze and convey information. But these new tools are being developed and deployed so quickly, it can be hard to stay on top of them all.

Below, we review some of 2017's conservation tech trends that have helped researchers and conservationists better understand their species and systems of interest, monitor their status and take actions to conserve them. We hope Mongabay-Wildtech's coverage of their experiences will help readers advance their own projects and priorities.

Understand Target Species and Systems
1. Camera traps are remote cameras that take photos when a sensor is triggered by the movement of an animal or person and, increasingly, send the image in real-time to the operator. They have helped researchers document the presence of elusive wildlife for decades, but innovative scientists have begun to apply this technology to new environments and species. The installation of camera traps in trees, for example, has successfully documented canopy use by arboreal mammals. Wildtech's coverage (our most popular post this year) includes the scientists' proposed solutions to various challenges faced in deploying cameras in the canopy.
Studying species in the dark requires its own technology. Researchers in the U.S. adapted thermal imaging sensors—which detect the heat energy emitted by animals—to study hibernating bats in caves and their response to white-nose syndrome.
Hummingbird researchers adapted this popular technique by separating the sensor from the camera to give cameras time to film the tiny, fast-flying birds. The do-it-yourself system allowed the researchers to use their own high-speed video camera and multiple independent sensors to detect the birds at different flowers. The adaptable setup could help other studies where a specialized camera or sensors are needed.
The hummingbird camera trap trigger system setup connects a high-speed video camera (covered, on the left) to two sensors, one on either side of the target Heliconia flower, to detect and begin filming the bird before it reaches the flower. Rico-Guevara and Mickley (2017).
As the number of camera trap studies increases, so does the number of "bycatch" photos—pictures taken of species that are not the target of the study for which the camera traps were deployed. One research team has urged researchers to share their photos of non-target species, especially those for which few occupancy studies exist, for others to use. They also crafted suggestions for making bycatch photosets easier to find, search and utilize.
2. Automated bioacoustic monitoring devices remind us that animals make a lot of noise. Acoustic sensors can play a role similar to that of camera traps by recording the presence of animals through their sounds 24/7, at relatively low cost, and storing them in a web-based platform for users to manage and analyze the data.
They are particularly useful for aerial and underwater species that move in three dimensions, rather than along trails. For example, researchers in Mexico detected the decreasing number of vaquitas through acoustic monitoring of their home in the Gulf of California. Passive acoustic monitoring devices set at spawning locations have allowed researchers to measure fish abundance independent of catch data. Bioacoustics are increasingly helping scientists understand overall ecosystem health, even underwater.

Above-ground, acoustic devices have helped researchers relate the buzz signatures of wild bees to their body measurements and pollination potential, as well as the composition of the bee community in a given area.
Acoustic sensors can also detect human sounds and alert authorities or local indigenous groups in near real-time when chainsaws are detected in their forest.
New users of these and other data-collection technologies can learn more from a comprehensive new online resource, launched in 2017, that details best practices for using specific technologies, including camera traps, acoustic monitoring and LiDAR.
3. Technology to collect, process and analyze genetic data has provided a third unique method of detecting species' presence. A portable field lab called GENE was able to extract, amplify and sequence DNA even in the challenging field conditions of the Congo Basin. A separate research team also used real-time nanopore sequencing to develop a portable DNA sequencer to rapidly read the DNA of any organism, including plants.
Environmental DNA (eDNA)—collected from the environment (typically from skin, scales or scat) and thus non-invasive—is particularly helpful in searching for rare aquatic species and determining fish community diversity, which is difficult to survey manually.
DNA barcoding, which compares DNA samples of unknown identity to reference databases using a gene carried by all animals, has transformed species identification for researchers and wildlife officials alike. The RHODIS rhino database helps identify the origin of horn material carried by poachers or traders. Similarly, barcoding of even processed market specimens can help trade officials distinguish legal from illegal species: one study found that most shark and ray products are illegal. Recent breakthroughs in portability and barcoding technology have resulted in handheld DNA analysis devices that will help officials rapidly identify species from wildlife parts on site. Such knowledge is still just one aspect of tackling wildlife crime; application of DNA results in courts of law varies across countries, in part based on the system's presumption of guilt or innocence.
4. Researchers are using detection dogs in creative ways to meet the challenge of finding samples of genetic material of specific species in the wild. With their amazing sense of smell, certain dogs can be trained to detect scat of multiple target wild species—as well as ammunition, snares, humans, chemicals and invasive plants—faster and more effectively than people can. Dogs and the DNA in the dung they find helped researchers define movement corridors for several threatened carnivores in Argentina.
5. Generating and accessing big data has also never been easier.
Existing handheld data collection tools, such as CyberTracker and Open Data Kit, have inspired development of mobile apps for collecting, managing, and compiling data sets on specific taxa and ecosystems. India's M-STrIPES app enables field patrols to use smartphones to quickly collect and upload data on tigers and their prey to a central server to modernize the nation's tiger population estimates.

Fisheries, starting with the Pacific tuna fleet, are beginning to use onboard and portside mobile apps to document fish harvest in order to improve knowledge of population dynamics and transparency of fish catch across the fleet.

Learning apps provide a huge, varied audience with access to big data. Scientists and non-scientists alike can use their smart devices to share, inquire about, identify and use wildlife photos taken by thousands of users worldwide. The popular iNaturalist app has also incorporated algorithms to train software to recognize species automatically to speed identification for many common species.

The more structured Global Biodiversity Information Facility provides free online access to occurrence records on nearly two million species, data that permit broad-scale analyses and that would otherwise be impossible to assemble. The huge Zoological Information Management System (ZIMS) database on the diets, health, genetics and breeding pedigrees of 21,000 species of captive animals, while not free, is now available to other wildlife institutions.
Monitor Their Status
6. The unprecedented availability and reduced cost of aerial imagery—collected by sensors on small unmanned aerial vehicles (UAVs or drones, to count individual trees of target species), satellites (to analyze site- to regional-scale forest change), or anything in between—continue to revolutionize not only the collection of habitat data but also the monitoring of habitat at ecosystem and landscape scales.
Open-access online mapping and data sharing platforms apply novel data storage and analysis capabilities to help anyone observe large-scale changes in vegetation over time. Map 4 Environment serves as a repository for spatial data sets and offers non-experts simple tools to share and manage the data and produce maps online. Also for non-technical users, Collect Earth allows teams with local knowledge to monitor land use change using point sampling tools and a large compilation of high-resolution images.

Global Land Analysis & Discovery (GLAD) alerts go one step further by not only detecting fine-scale forest loss in near-real time but also notifying users of this change via email to enable rapid response.
7. Combining remote sensing imagery with other types of data can facilitate monitoring, especially over vast areas or in remote areas with rugged terrain. With sharks threatened by overharvest, researchers compared simultaneous locations of satellite-tracked fishing vessels and tagged shark locations to examine proximity and potential threat to sharks from accidental or deliberate catch.
Research linking high-resolution imagery to detect high-carbon tropical forests with camera trap photo data to assess species presence showed that high-carbon forests support more wild species. For finer-scale monitoring, scientists in Australia outfitted UAVs with video cameras and artificial intelligence algorithms to identify individual koalas during aerial surveys to improve monitoring of populations of hard-to-find species over time.

Ugandan park rangers who used GPS units to assess accuracy of GLAD alert locations found that the satellite-based alerts could make field patrols more effective, with the caveat that projects consider the personnel, logistics and training needed to enable on-the-ground action.
Enlist a Broad Audience to Take Action
Recent tech developments encourage everyone to help advance biodiversity and ecological research, as well as draw attention to threats and changes to natural systems.
8. Apps that enhance real data with augmented reality may increase empathy for wildlife among gamers and other groups not traditionally active in conservation, while mobile technologies such as TIMBY allow concerned citizens to securely report (illegal) activities in their communities, providing unique evidence of what's happening on the ground.
Free online tools that make documents and data related to the US Endangered Species Act more accessible help both officials and the public assess how the law is implemented, a service that could better connect citizens elsewhere with their countries' environmental laws.

9. Online and mobile sharing of data and photos, in particular, have expanded the opportunities for citizen scientists to learn about the species around them, assist research projects and feel part of a learning community. Scientists analyzed georeferenced bird photos shared by hundreds of people through the eBird app to document seasonal changes in bird distributions. Wildbook software helps projects store and manage wildlife data by analyzing photos contributed by anyone to determine, based on an animal's unique markings, if it is a new individual or an animal already in a project database.
10. Crowdsourcing data collection and processing can also be as simple as enticing volunteers to walk around, collect environmental data on their phones and submit samples of the soil on their boots to help researchers analyze pathogen distribution.
Processing the mountains of data generated by drone flights, camera traps and databases presents a challenge for cash-strapped conservationists and researchers. Some have turned to citizen scientists to help identify target species, including Amazon trees and African elephants, in photos and videos. The resulting abundance or demographic data can be used to focus conservation efforts on key locations, but maintaining data quality collected by citizen scientists requires careful planning and effort.

Human actions have taken a steep toll on whales and dolphins. Some studies estimate that small whale abundance, which includes dolphins, has fallen 87% since 1980 and thousands of whales die from rope entanglement annually. But humans also cause less obvious harm. Researchers have found changes in the stress levels, reproductive health and respiratory health of these animals, but this valuable data is extremely hard to collect.

A Lot to Learn From Hormones<p>When sampling the blow, we are looking for hormones in mucus as these can be used to gauge psychological and physiological health. We are specifically interested in <a href="https://dx.doi.org/10.1371%2Fjournal.pone.0114062" target="_blank">hormones like cortisol</a> and <a href="https://doi.org/10.1016/j.ygcen.2018.04.003" target="_blank">progesterone</a>, which indicate stress levels and reproductive ability respectively, but can also help determine overall health.</p><p>Additionally, blow samples can detect <a href="https://dx.doi.org/10.1128%2FmSystems.00119-17" target="_blank">respiratory pathogens</a> in the lungs or nasal passages - blowholes evolved from noses after all.</p><p>This health analysis is especially important in areas with oil spills as the chemicals can cause hormonal problems that harm <a href="https://www.carmmha.org/investigating-how-oil-spills-affect-dolphins-and-whales/" target="_blank">development, metabolism and reproduction</a> in dolphins.</p><p>Hormone samples can provide scientists with valuable data, but collecting them from intelligent and unpredictable animals is challenging.</p>
Cetacean Collaborators<p>To build a drone that can stealthily collect spray from moving dolphins, we needed more data on their eyesight and hearing, and this is data that couldn't be collected in the wild nor simulated in a lab.</p><p>We worked with dolphins at facilities like Dolphin Quest in Bermuda, which provides guests opportunities to learn about dolphins while allowing <a href="https://dolphinquest.com/about-us/our-story/" target="_blank">scientists access to animals for noninvasive research</a>. Here the dolphins can swim away if they choose not to work with us, so we had to design the study like a game; the way a kindergarten teacher entertains a class. If the dolphins aren't interested, we don't get to do the science.</p><p>Over the course of hundreds of sessions, we sought to answer two questions: What can dolphins hear and what can they see around their heads?</p><p>To test dolphin hearing, we set up microphones and cameras to record dolphin behavior as we played drone noise in the air. We analyzed the responses to each noise – such as how many dolphins looked at the speaker – and used these as a proxy for their ability to hear the sounds.</p>

Robodolphin doesn't look like a real dolphin, but it doesn't need to in order to train our drone pilots. C.J. Barton / Oklahoma State University / CC BY-ND<p>To build robodolphin, we worked with dolphins trained to "chuff" or sneeze on command to measure spray characteristics. We used high-speed photography to see the dolphins' breath as it moved through the air. Then we conducted high resolution CT scans of a dolphin head and 3D-printed a replica of a nasal passage.</p><p>Now, we have a complete robodolphin and are tweaking its sprays to be nearly identical to the real thing. This will allow us to determine how close we need to get to collect the samples, and therefore, how quiet our drone needs to be.</p>

A Bit of Practice, Then Into the Wild<p>In the next few months, we will test flights over robodolphin with existing drones to determine the timing and strategy for collection. From there, we will fabricate a low-noise drone that can fly fast enough and with sufficient maneuverability to capture samples from wild dolphins. Like a video game, we will use the visual field data to develop approach trajectories to stay in the visual blindspots.</p><p>We plan to test our drones on a truck-mounted robodolphin moving down a runway, then using a boat to simulate realistic conditions. The next steps will involve ocean testing with dolphins trained for open ocean swimming. These tests will determine if our devices can catch and hold the hormones as the drone flies back to a researcher's boat.</p><p>Finally, we will deploy the system to collect data on wild dolphins. Our first goal is to test resident dolphins – animals that live on the coasts and deal directly with boat and oil industry noise – which will allow us to learn more about stress resulting from human impacts.</p><p>Those samples are a way off, but if all goes well we will have a specially built drone capable of flying long distances and capturing samples undetected in a few years. The samples collected will allow researchers to do better science with impact on the animals they study.</p>

Billions worth of valuable metals such as gold, silver and copper were dumped or burned last year as electronic waste produced globally jumped to a record 53.6 million tons (Mt), or 7.3 kilogram per person, a UN report showed on Thursday.
Environmental and Health Hazard<p>Experts say e-waste, which is now the world's fastest-growing domestic waste stream, poses serious environmental and health risks.</p><p>Simply throwing away electronic items without ensuring they get properly recycled leads to the loss of key materials such as iron, copper and gold, which can otherwise be recovered and used as primary raw materials to make new equipment, thereby reducing greenhouse gas emissions from extraction and refinement of raw materials.</p><p>Refrigerants found in electronic equipment such as fridge and air conditioners also contribute to global warming. A total of 98 Mt of CO2-equivalents, or about 0.3% of global energy-related emissions, were released into the atmosphere in 2019 from discarded refrigerators and ACs that were not recycled properly, the report said.</p><p>E-waste contains several toxic additives or hazardous substances, such as mercury and brominated flame retardants (BFR), and simply burning it or throwing it away could lead to serious health issues. Several studies have linked unregulated recycling of e-waste to adverse birth outcomes like stillbirth and premature birth, damages to the human brain or nervous system and in some cases hearing loss and heart troubles.</p><p>"Informal and improper e-waste recycling is a major emerging hazard silently affecting our health and that of future generations. One in four children are dying from avoidable environmental exposures," said Maria Neira, director of the Environment, Climate Change and Health Department at the World Health Organization. "One in four children could be saved, if we take action to protect their health and ensure a safe environment."</p>
Europe Leads the Way<p>While most of the e-waste was generated in Asia (24.9 Mt) in 2019, Europe led the charts on a per person basis with 16.2 kg per capita, the report said.</p><p>But the continent also recorded the <a href="https://www.dw.com/en/the-eu-declares-war-on-e-waste/a-51108790" target="_blank">highest documented formal e-waste collection and recycling</a> rate at 42.5%, still below its target of 65%. Europe was well ahead of the others on this front. Asia ranked second with 11.7%.</p><p>The authors said while more that 70% of the world's population was covered by some form of e-waste policy or laws, not much was being done toward implementation and enforcement of the regulations to encourage the take-up of a collection and recycling infrastructure due to lack of investment and political motivation.</p><p>"You have to think about new economic systems," said Kühr.</p><p>One approach could be that consumers no longer buy the products, but only the service they offer. The device would remain the property of the maker, who would then have an interest in offering his customers the best service and the necessary equipment. The maker would also be interested in designing his products in such a way that they are easier to repair and easier to recycle, Kühr said.</p>
