I like the idea of the regenerating shoot- really links well with conservation and restoration. Could you try a few different fonts- and don't use a capital for the 'L' as it looks a bit like' is land net' at the moment. Also try having 'island' in green (but different green to the plant shoot), and 'Net' in light blue with a capital 'N'?
now that I can see it on screen I think using green text makes it look too much like 'Yisland'. Can you try blue again like in #12 but use a capital N for net? So, try 'islandNet' and 'IslandNet' (note where I've used the capital letters) - and use a font that makes the capital 'I' and little 'l' look different when you write 'Island'? I like the type of font you used in #12- it's not as formal looking as #58, but I think it would make the capital 'I' and little 'l' look the same- is there a similar looking font that can make these letters look different?
Here are the revised logo as your request. The 'I' is using capital letter and the 'l' (L) has customized with small hook to make it different from 'I' (i). Also the 'N' now is capital.
