Aldrovanda red listed

Recommended Posts

Aldrovanda made the IUCN red list!

Adam Cross not only wrote a pretty good book, he also submitted his research to the IUCN who responded by placing Aldrovanda on their red list.

It's been a long time since a CP has been added and it was long overdue.

Yes they are, and orinating from the time there where still dinosaurs arround. And hopefully they will exist for many more centuries to come so they need good protection.

Especially the protection of their habitats where they grow! Habitat lose is the biggest problem with this plant!

Aldrovanda is as much an endagered species as the tiger! And in Nieuwkoop they tried to get rid of the Aldrovanda a couple of years ago as ''it was considered an exotic pest wich had to be eradicated'' while it got extinct somewhere near Hamburg and Lubeck probably last century! Well in Adam Cross his book there is a whole list of former German sites where it got extinct.

And I guess they make a mistake by saying that Aldrovanda is an exotic plant here, as it could be very well possible that Aldrovanda was found here in the warmest period of the Holocenic period about 6000 years ago. During that period the European terrapin, Emys orbicularis, was found in The Netherlands. They have even found fossils from this reptil not far from where I live wich is near The Hague. So as Aldrovanda seems to like a bit warmer summers as we have here in The Netherlands, it could have got extinct here by the time the climate got cooler again. And it seems Aldrovanda has never been a very common plant so finding fossil remaines is a bit like wining a lotery I guess. And as most peat deposits here in The Netherlands have been ended as a fuel for heating in the past wich means fossil remaines like pollen have got lost also.

But now with Global warming it can make a comeback here. Well it has allready in Nieuwkoop. They should place that area maybe on the Ramsar list . Even if it where for an exotic pest like Aldrovanda...
