I spent part of today showing Environment Canterbury staff the only known spot in the South Island with long-flowered Veldt grass, Ehrharta longiflora. It's a potential new weed, and it's so far only known from one location in Ōtautahi-Christchurch (at the base of Hackthorne Road). Please keep an eye out for it, and upload a photo to #iNaturalist if you think you've found it.

Yesterday @KorimakoEcology posted about what a horrible weed Phoenix palm is becoming in parts of NZ. Inspired by that, I went through the observations on #iNaturalistNZ and set "Organism is wild" to "No" for about 50 observations of clearly planted palms. Now, a search for Phoenix palm correctly maps out wild Phoenix palms. (When uploading to #iNaturalist, please do always check the "captive/cultivated" box for planted plants.)

A good example of why #PhoenixPalms are such a problem #InvasiveWeed.

They happily germinate in complete darkness, and this one has pushed up through the pavement and is looking very healthy.

There is the stump of an adult palm on the other side of the fence that was cut down ~18 months ago.
