Are you doing vegetation surveys for jaguar habitat? Check out Mapir.com
I am starting a similar project for mapping desert riparian habitat. I think in your situation though, you will need a bigger drone like a Inspire with more capabilities like a true multispectral camera or even Lidar, etc., it depends in what you are mapping or measuring. Are you going for simple canopy cover estimates? A basic NIR RGB camera like the Mapir3 that Mapir.com sells may be good for they differentiate soil from foliage, but if you are measuring canopy height and density, I’d think you would need more capabilities like maybe even Lidar and some funding, too.
Have you secured funding, or considered a Go Fund Me campaign, too? There are lots of good conservation based financing opportunities if you are doing the project for an educational or non profit research project.
And watch out for Harpy nests!
