The HydroLibrary is Hydroscape's species and ecosystem database. Over 500 species cards, 18 water quality reference cards, 22 habitat projects, 5 deterrent methods, and 22 conservation authority profiles — all free, in 22 languages, no login required.

Identifying a species well means understanding more than what it looks like. It means knowing its conservation status (does this record matter more than others?), its typical habitat (does the location match?), and any reporting obligations (is this a notifiable species?).

Similarly, when you see a water quality issue, the reference cards give you a starting point for interpretation — "algal bloom" is a very different conversation from "normal summer colour."

The library exists to make your records better-informed and better-targeted.

Three routes:

The HydroLibrary is fully open. You don't need a MyHydroscape account. You don't need to download anything. You can use it as a general UK wildlife reference even if you never submit a sighting.

The whole library translates on the fly. Tap the language selector at the top of the Hub or HydroLibrary to switch. Useful if English isn't your first language, or you want to share a species card with someone who doesn't read English.
