Overview nature conservation areas and locations of threatened species 2017-2019, Finland 314 locations with Alisma wahlenbergii 68 locations with Crassula aquatica 46 locations with Hippuris tetraphylla 100 locations with Persicaria foliosa
5,5% of all Finnish SEAmBOTH locations 2017-2019 contained a threatened species
On average: for every 10 threatened species found inside a nature conservation area, 1 threatened species was found outside these areas. Locations with high density
• Kemi river estuary • Ulkokrunni • Ii / Haukipudas • Kraaseli / Oulu bay area • Hailuoto NE shore • Kempeleenlahti
Average occurence of threatened species per square kilometer Measuring water quality from space
● Satellites measure sunlight reflected by water ● This light contains information about various substances in water ● Mathematical models can be used to estimate: • Chl-a, turbidity, transparency, humic substances
Main advantages:
- Good spatial and temporal coverage 33 - Cost effective monitoring Turbidity composite of summer 2017 14.05.2019 60 m pixels River input

People we have met: Case officers in nature conservation Case officers in water protection National agency of marine management (SWAM) NGOs Examples of their comments & requests: School teachers Boaters, scuba divers, recreational users of sea “Maps showing nature values highly useful” Fishermen (professional and recreational) “Good to know potential distribution of threatened species” Consultants “A book/booklet with information about occurring species University students and researchers within the area” Private conservation area representatives “Any kind of map that show potential nature values under People in tourist industry water is helpful as we now have nothing to use as Municipality and city representatives background for motivation in e.g. permission cases” Harbour representatives “Data published and available for public” Search and Rescue people “Data of depth (bathymetry) is vital to get” Clay labyrinth, Simo, Finland Welcome to SEAmBOTH final seminar in Oulu, Finland, 20.02.2020 University of Oulu, Lecture hall L5 Thank you for your interest!
