Excellent idea, kueda. The hurdles are low, if anything.
If you wanted 50 research grade observations, I would object, because that might lock out someone like danaleeling because there may not be enough identifiers familiar with Micronesian plants. But 50 verifiable observations can be gathered in well under 2 hours with an app-equipped smartphone and the ability to upload without breaking the budget.
Working with an older camera (non-geo-tagging) and a computer might take several times that long, but the requirement is still reasonable.
