What is a biodiversity charity?
A biodiversity charity works to protect the variety of life on Earth: the species, habitats, and genetic diversity that keep ecosystems functioning. The directory above lists organizations tagged to this cause, from small local habitat-restoration groups to international conservation bodies. GiveRadar derives the tag from a charity's name, stated mission, and registry classification; charities have no way to choose or buy it. Filter the list by country and by organization size to narrow it to the groups you want to look at.
A biodiversity charity is a nonprofit that works to protect and restore the variety of living things and the ecosystems they depend on, from individual threatened species to whole habitats and the genetic diversity within them. These organizations range from volunteer-run local conservation trusts to large international bodies, and their work spans field projects, scientific monitoring, policy advocacy, and public education. Every organization tagged to this cause on GiveRadar is listed with the same profile: registration where a registry publishes it, filed financials where available, leadership, and an integrity assessment.
What do biodiversity charities do?
Biodiversity charities focus on halting the loss of species and habitats and rebuilding ecosystems where they have been damaged. Typical projects include:
- Restoring and protecting habitats such as wetlands, meadows, hedgerows, and native woodland
- Surveying plants, insects, and other easily overlooked species to map where variety is being lost
- Safeguarding the genetic diversity of wild plants through native seed collections and propagation programs
- Managing invasive species that crowd out native plants and animals
- Advocating for stronger habitat protection and biodiversity policy
- Educating communities, landowners, and schools on supporting local wildlife and pollinators
- Funding conservation research and mapping where biodiversity is most at risk
How to check a biodiversity charity before you give
Biodiversity work often plays out over decades and in places donors never see, so look for organizations that report on the ground they hold or manage, the species or habitats they track, and the outcomes over time rather than a single appeal. Confirm the charity is registered, read who runs it, and check when it last filed: long-running conservation projects should show a steady filing history, and a large gap is worth a question. The integrity assessment on each profile measures disclosure and governance signals, not conservation impact, so treat it as a transparency check and read the filings yourself. Our guide for donors walks through the full check step by step.
Common questions
What is a biodiversity charity?
A biodiversity charity is a nonprofit working to protect the variety of life on Earth: species, habitats, and the genetic diversity that keeps ecosystems healthy. Its work can include habitat restoration, species surveys, recovery programs for threatened plants, and conservation policy. The directory above lists these organizations and can be filtered by country and size.
How can I help biodiversity by donating?
You can support biodiversity by funding organizations that protect or restore habitats, monitor threatened species, or work on conservation policy, and the directory above lets you filter them by country and size. Before you give, confirm the charity is registered, look at its filings and leadership, and read its integrity assessment, which measures disclosure rather than conservation impact. Smaller local groups and large international bodies both appear here, so choose the scale and focus that match what you want to support.
