AI Cuts Wildlife Tracking Time from Months to Days
Speed and knowledge matters in protecting endangered wildlife, so identifying species quickly from a flood of images could inform timely conservation decisions.
Artificial intelligence can dramatically speed up the painstaking work of tracking wildlife with remote cameras, cutting analysis time from months or even a year to just days while producing nearly the same scientific conclusions as humans.
That’s according to a 2026 study led by researchers at Washington State University and Google, published in the Journal of Applied Ecology. The team tested whether a fully automated AI system could replace humans in processing hundreds of thousands to millions of camera trap images collected in Washington state, Montana’s Glacier National Park, and Guatemala’s Maya Biosphere Reserve.
They found that, for most species, models built from AI-identified images closely matched those produced by human experts. Across key measures such as where animals occur and what environmental factors influence them, the results aligned in roughly 85–90 percent of cases, with limited divergence for rare or difficult-to-identify species.
The implications could be significant for conservation. Faster processing means researchers and wildlife managers can move more quickly from collecting data to making decisions, potentially enabling near-real-time monitoring of species such as jaguars, wolves, and grizzly bears.
“We’re not trying to replace people,” says WSU wildlife ecologist Daniel Thornton, lead author of the study. “The goal is to help researchers get to answers faster so they can make better decisions about managing and conserving wildlife.”
Traditionally, that process has been slow and labor-intensive. Camera traps, which are motion-activated cameras placed in forests and other habitats, can generate enormous datasets. A single project may produce hundreds of thousands or even millions of images that must be reviewed to determine which species appear in each frame.
Even with a team of undergraduate assistants and a graduate student verifying identifications, Thornton says the process typically takes six to seven months, and sometimes up to a year, before analysis can begin.
Early AI tools offered some relief by filtering out blank images, often 60–70 percent of the total, but still required humans to review tens of thousands of photos containing animals. The new study tested whether that final human step could be eliminated.
Using a general AI model called SpeciesNet, developed by Google, the researchers ran images through a fully automated pipeline with no human review and compared the results to traditional, expert-labeled datasets.
“The key question wasn’t whether the AI got every image right,” says Dan Morris, a senior staff research scientist at Google who helped create SpeciesNet and is a coauthor on the study. “It was whether the ecological conclusions you care about would end up being basically the same.”
For most species, they were. Even when the AI made mistakes, such as misidentifying animals or missing detections, the overall models remained robust because occupancy models rely on repeated observations over time.
In practical terms, the time savings are dramatic. Fully automated processing can now be completed in just a few days, reducing a months-long bottleneck to roughly a week.
That efficiency could be transformative, particularly for smaller or underfunded conservation groups. It may also allow researchers to expand monitoring efforts without being limited by data processing capacity.
The project also contributed to the broader AI-for-conservation community by making part of its dataset publicly available, helping support tools like SpeciesNet that rely on shared data to improve.
Morris emphasizes that the study takes a practical approach. Rather than developing new AI algorithms, the team focused on what current tools can already do.
“We weren’t trying to invent a new model,” he says. “We were asking whether, given where the technology is today, people can rely on it for the kinds of analyses they already do.”
The answer, at least for many common species and standard ecological models, appears to be yes.
There are still limitations. Human review is needed for many other applications of camera trapping data, and this paper only dealt with a small subset of species that may be caught on camera. For example, very rare and easily confused species are still problematic for AI detection. But the findings suggest that in some cases, image processing no longer needs to be a major constraint on large-scale camera-trapping studies.
“The big takeaway is that this doesn’t have to be a bottleneck anymore,” Thornton says. “If we can process data faster, we can respond faster, and that’s really what matters for conservation.”
