Why make a herbarium ?

A herbarium will help you in organizing your sighting, and is a precious tool when you will discover new plants : you will be able to compare some parts of the plants you've never looked at before, etc..

Herbarium help scientists to enhance their knowledge on biodiversity.

But this is only a series of pictures, not a real herbarium !

Sure, you don't have the real thing in your herbarium, only a picture. But as you have given a lot of data (date, place, details of observation) you have a real tool to gain a better understanding of nature.

And very soon the website will guide you in the collection of sample of plants, to have a complete record of each sighting.
