Green-blue algae in Forum pond

For a few weeks now, the Forum pond has been looking green and murky. The culprits are potentially dangerous blue-green algae, mainly Dolichospermum flos-aquae.

According to Edwin Peeters and Miquel Lurling of Aquatic Ecology and Water Quality Management (AEW), the growth of the algae suggests an excess of fertilizer chemicals in the pond. The cold spring may have played a role in this, as it caused a delay in the growth of aquatic plants which normally compete with the algae for nutrients. The building of the wooden decking on the banks might have contributed too. Blue-green algae can give off toxins which are harmful to humans and animals. Paddling is therefore not advisable at the moment.

    Tekort aan waterplanten..tsja wanneer je alles wegbaggert in de herfst duurt dat herstel inderdaad langer

    Dit is nu al de zoveelste keer, wij aquatisch ecologen schamen ons kapot voor dit wanbeleid. Hoe gaat dit verder? Wanneer stopt deze onzin? Mensen blijven klagen over de teloorgang van de Forumvijver, maar oplossingen bedenken? Hó maar!
