There's no quick and easy answer to that question, it all comes from a lot of different places.
I have spent my entire life loving animals and the natural world, reading books, watching shows, visiting museums and taking everything in, so naturally some things just come from my gained knowledge from a lifetime of being passionate about everything wild. Alongside that knowledge I also continue to use books, websites, documentaries and museums etc to look up and confirm any information that I need for various products. I always look for any facts to be confirmed in a number of locations before I use them.
So with all of that its hard to give a definitive list, so below is a list of various resources that I hope will help you expand your knowledge or our natural world. Some i have used and some I haven't but as I discover them I thought it would be great to keep a list of them all. I have also been very lucky to have been helped along the way by some amazing people who have given me their own expertise to help me.
Amazing Organisations that have helped me along the way...
The Shark Trust
Monkey World, Dorset
Monkey Forest, Trentham

I will aim to update this list going forward with new resources that I discover or remember. Hopefully it will form a fantastic list of resources for budding nature lovers to expand their knowledge of our natural world. Equally if you know of any amazing resources that I should take a look at please do pop me an email so i can check it out.
