Water plant cover IJsselmeer area — mattenbies — 2014

Water plant cover IJsselmeer area. The water plant cover in the IJsselmeer area is monitored every three years. That is to say, in a three-year cycle in each part of the area, water plant cover shall be identified: in 2016 in the Markermeer and IJmeer, in 2017 in the IJsselmeer, and in 2018 in the edge lakes. NB: the Veluwemeer was not area-covered in 2018, but in a limited number of locations.For every year there is a dataset per species of aquatic plants found and a dataset with the total coverage present. These datasets are interpolated data. In addition, there is a dataset per year with the (point) locations of the field observations.In these datasets information from the years 2011 to 2018. Overall, the zone of 0-3 meters depth is calibrated. See the “Punts map field observations” layer for a view of the measuring points. Watch out! Aquatic plants can also occur outside the serrated zone.
