Invasive non native species

[tracy]

Invasive non native species are often a threat to our own, my friend Paul sent me this link

http://www.nonnativespecies.org/

which seems interesting! I am keeping a close eye on what is appearing in our pond!

I read the other day that Rhododendon can carry Phytophthora - which is a fungus that is killing some of our chestnut trees.

Yes another reason to get rid of it then!

Naomi has a problem with fringed sedge in her woodland. Anyone know anything about this species?

Interesting I’ve never come across a species such as fringed sedge, I did google the name and found this: http://research.plattsburgh.edu/wetlandmonitoring/Plant%20ID%20manual/Carex%20crinita%20crinita.pdf

If in doubt ring up plant life for identification

This is a shot in the dark but it might be Greater Tussock-sedge, which is very rear in Sussex.

It is the North American fringed sedge that we have in our woods. Many people in the area have found it arriving in their gardens too. The problem is that nothing eats it, not even deer, and it spreads very rapidly. Unfortunately it occupies more and more of the damp ground competing with native orchids and bluebells. No prizes for which species is winning.
