Question

animal populations in the wild have dropped by half over the last 50 years, placing many of them on the endangered species list. nature preserves are created to help protect endangered species in their native habitats. however, people still illegally hunt animals in and around these preserves.
ecologists use modern technology to track, observe, and develop plans to help protect endangered species.
select three technologies ecologists can use that are the least invasive in the native habitat.
drone (unmanned aerial vehicle) patrols
satellite imagery from existing satellites
wireless wildlife cameras (mounted in the habitat)
nature identification (cellular) apps used by visitors
trapping and collaring individual animals with gps monitors
drones
satellite imagery
wireless wildlife cameras
nature identification (cellular) apps used by visitors
trapping and collaring animals with gps monitors

Explanation:

• Drone patrols: Drones (unmanned aerial vehicles) can survey large areas without direct physical contact with the habitat or animals. They can fly over and observe from above without disturbing the natural environment significantly.
• Satellite imagery: Using existing satellites to get imagery is non - invasive. Satellites orbit the Earth and can provide data on habitat changes, animal movements (to some extent) over large areas without any on - the - ground or in - habitat interference.
• Wireless wildlife cameras: Mounted in the habitat, these cameras can record animal behavior without direct human presence or interference most of the time. Once installed (with minimal disturbance during installation), they can passively collect data.

Trapping and collaring animals with GPS monitors is invasive as it involves capturing the animals. Nature identification apps used by visitors may rely on human observation which can be more disruptive (e.g., visitors may wander off paths) compared to the first three technologies.

Answer:

Drone (unmanned aerial vehicle) patrols, satellite imagery from existing satellites, wireless wildlife cameras (mounted in the habitat)
