Any user can comment on any other users spottings, to answer your question. As you can see, there are certain things people see that irritate them, such as this spotting. We are a community of nature lovers and don't like seeing wildlife dead, but can usually accept it when it has died of natural causes or predation. Cats are a touchy subject because they are only here because humans brought them here, and for many people that is not a justification for letting them kill whatever they want.
If you want your students to use this site, it can be very helpful for them. But I cannot stress how important it is for them to first read our FAQ, especially the part "What types of photos should I submit as spottings?" Here's what it says:
"The best submissions are of an individual species with several clear photos and detailed notes. This remains true whether you’ve encountered an orchid or an orca. We understand that sometimes you might not have the chance to snap multiple photos or even one properly focused photo and that is OK, but please make sure that the species involved can be clearly seen and is recognizable. Our community enjoys learning about the circumstances leading up to your encounter and providing more information along with more photo angles can help tremendously with identification.
Although sunsets and landscapes make for beautiful photographs, we are focused on documenting specific species so unless there is a sea gull flying across the sunset or a grouping of pine trees in the middle of the landscape, please refrain from submitting those types of photos. There are other great sites for that sort of photography.
We also request that photographs are submitted in as natural a state as possible. We appreciate that often there will be a need to carry out minor improvements such as cropping, lightening and sharpening an image so that we can better see the detail of the organism it portrays. These minor improvements are perfectly acceptable but we do request that heavily Photoshopped or otherwise manipulated images are not shared on this site.
Please also refrain from posting spottings of people; we appreciate that on occasions you may have a wildlife spotting that includes a person in the photograph - in this instance please crop your photograph so that the animal or other organism remains the focus of the image.
As we are a community of wildlife lovers, we request that you do not post any images that may cause offense to other users, such as hunting or fishing trophy photographs. We also ask that you do not add dead organisms except those taken as food by living organisms in their natural habitat.
Our primary focus is wildlife, and although we do accept pet photographs, we do not encourage it and we ask that these spottings be assigned to the "Pets" category.
Remember, any photograph you submit must be your own work, or you must have permission from the original photographer to use the image. Photographs copied from the Internet or other sources may infringe copyrights so we cannot accept them."
If the students can follow the guidelines for this site, then there won't be any problems. This is a great place for them to learn more about wildlife in their area and around the world and to get things identified for them that they may not have known in the past.
For the developers at New York start-up Networked Organisms, smartphones are the butterfly nets of the 21st Century. Their tool, Project Noah, lets people upload photos of plants and wildlife around them, creating a map of the natural world and contributing to scientific research in the process.
Bespectacled scientists of yore would carry around hefty field guides, made up of hundreds of pages of text and photos. But these days, smartphone owners have a lighter option: an app called Project Noah, which aims to help people identify plants and animals as well as collect data from "citizen scientists" about where certain species are located.
Project Noah enables us to be part of a more focused online community where we can learn more about wildlife around us and contribute to scientific research. It pulls participants into deeper, more meaningful engagement by enabling people to go on “missions” to collectively map changes based on sightings.
A modern invention that may also hold the key to saving species in the future. Project Noah is a global study that encourages nature lovers to document the wildlife they encounter, using a purpose built phone app and web community. In addition to the virtual "collection" of species, Project Noah encourages citizen science by linking up with existing surveys including the International Spider Survey and the Global Coral Reef Monitoring Network.
