  • The Christmas Bird Count is one of the most popular bird projects in North America; it now contains more than a century of data on early-winter bird populations across the Americas.
  • eBird is a real-time, online checklist program that was launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society.
  • The Great Backyard Bird Count is an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across North America.
  • USA National Phenology Network brings together citizen scientists, government agencies, non-profit groups, educators and students to monitor the impacts of climate change on plants and animals in the United States.
  • NatureWatch is a suite of monitoring programs, including FrogWatch, PlantWatch and more.
  • Citizen Science Social network: a weblog on citizen science projects.
  • Project BudBurst engages the public in the collection of important climate change data based on the timing of leafing and flowering of trees and flowers.
  • In the Great Sunflower Project, volunteers track bee numbers at sunflowers in their gardens.


  • BirdTrack is an online bird recording scheme by the British Trust of Ornithology, RSPB and Birdwatch (Ireland) for the region of Britain and Ireland.
  • Nature's Calendar is the home for thousands of volunteers across the UK who record the signs of the seasons. The project records a wide variety of natural seasonal events such as arrival of migratory birds, first appearance of insects in spring and flowering of plants.
  • Breeding Bird Survey is the main source of population trend information about the UK's widespread birds - an important indicator of the health of the countryside. It can only produce trends for birds found on 40 or more BBS squares, so the more squares covered, the more species we can monitor.


  • The Toad NUTS (Noordhoek Unpaid Toad Savers) are a group of volunteers based in Noordhoek, Cape Town, South Africa with the sole aim of saving the endangered Western Leopard Toad.


  • Earthdive is a global marine research project for millions of recreational scuba divers. At the heart of this unique research project is the Global Dive Log, which is a database into which divers (and snorkellers) log sightings of key indicator species and human induced pressures.
