Ground Truth.
A living resource on natural capital, nature finance and ecological restoration.
Nature finance is full of language that obscures more than it explains. Acronyms compete for attention. Frameworks stack on frameworks. The same fact is reported four different ways depending on who is paying for the report.
Ground Truth is the opposite of that. One person, working inside the field, writing things down clearly. The aim is to leave a trail that someone three years in could follow without needing a glossary in their other tab.
I am a Natural Capital Developer at Restore, building the voluntary 30x30 Restore Unit and the buyer-side market for verified British ecological recovery. Before that, fifteen years filming wildlife and rewilding for the BBC, Netflix, National Geographic and PBS.
This site is where I put the things I would have wanted when I was new to the sector, and the things I think the sector itself should be saying out loud.
Each of these is a live document. They will be updated as the field changes, which is often.

Before
Wildlife filmmaker, 15 years
Based
Bristol, UK
I joined Restore in February 2026 after fifteen years filming wildlife and rewilding for the BBC Natural History Unit, Netflix, National Geographic and PBS. The pivot from camera to commercial nature work happened on the Wild Hope series, where every story I filmed had a financial bottleneck behind it.
My job at Restore is to design and sell the 30x30 Restore Unit, a revolutionary new voluntary biodiversity unit. You can find out more at groundtruth.restore.owlettsfarm.com/30x30RU.
