(CNN) -- As a hobby, Suzie Jirachareonkul, a teacher and mother of two, spends many of her nights searching for endangered toads on the country roads near her home outside Cape Town, South Africa.



Volunteers in South Africa are collecting data on the Western Leopard Toad, which is endangered.



She often finds them flattened on the street.



"They're so beautiful and it's just really hard to live with, especially when you're living on the road right here," the 33-year-old said of the toad deaths. "So we started doing something about it. We started saving them off the road in the middle of the rain."



When a scientist caught onto her efforts, Jirachareonkul and a friend assembled about 20 volunteers -- a group she calls the "Toad NUTS" -- to collect data on the endangered Western Leopard Toad.



The information they collect is being used in scientific research.



Each time Jirachareonkul comes upon one of the spotted, faintly iridescent creatures, she springs into action. She marks down GPS coordinates, measures the toad, makes notes on its behavior (Is a mate stuck to its back? Is it headed toward a pond?) and uploads the information so scientists can use it.



Oh, and she moves the toad out of traffic's way, too.



While her nighttime hobby may sound a bit strange, Jirachareonkul is far from alone in her efforts to collect amateur scientific data.



At a time when climate change and urbanization are poised to set off a new wave of extinction, some members of the scientific community are turning toward backyard biologists for the data they need to monitor ecosystems and protect struggling species.



This "citizen science" movement is not exactly new, but it has grown fresh legs as the Internet and social-networking sites help people with uber-specified and often bizarre interests gang up for a cause.



Amateur-produced Web sites now serve as data hubs for squirrel sightings, bird photos, ant anthologies, snapshots of leaves, flowers and trees, water quality info, beetle hunts and firefly tracking, among others. Find links at CNN's SciTech blog



"It's pretty random," said Cyndy Parr of the Encyclopedia of Life. "There's a lot of charismatic things that won't surprise you -- backyard birds, that sort of thing. But there are also thriving communities of people who like to take pictures of butterflies, centipedes, wildflowers, plants."



Some of the sites have sweeping goals. The Encyclopedia of Life, which seeks to gather online information on all known species, has started taking public submissions through a public Flickr group. Some individual users have uploaded more than 2,000 photos.



Project BudBurst, out of Boulder, Colorado, aims to collect so much amateur data about plant species that scientists will be able to tell how climate change is altering the seasons in North America.



The venture, managed by the University Corporation for Atmospheric Research, gathers "data that would not otherwise be collected," said Sandra Henderson, the project's director. "We have these additional sentinel eyes on the landscape, if you will. There aren't enough ecologists to be making all of these different plant observations."



National Science Foundation funding for citizen science dropped off significantly in 2002 but generally has been on the rise since, according to budget numbers compiled for CNN. Since that year, funding in the United States has increased more than 240 percent, to more than $3 million for 2008.



Several of the Web projects receive government funding, but others survive on their own merits.



In Spain, Josep del Hoyo founded the Internet Bird Collection, an international compilation of bird videos, sounds and photos that's funded solely by his company. He said the intense passion of birders around the world, plus some money from his publishing company, keep the site running.



Amateurs have posted video of never-before-seen birds on the site, he said, and some of the work has been the foundation for scientific articles.
