Are Non-native plants a cause of the decreasing biodiversity?

    I don’t see a word on that website about L.japonica being invasive, dangerous to wildlife or a threat to anyone or anything.


    As I say, if it bothers you, get in touch with HM Govt and tell them. We on the forum, like the people on Naturespot, aren’t bothered by it.

    My variety (Hall's prolific) doesn't produce berries, meaning it cannot be invasive unless I let it grow out of bounds (but where it is that is close to impossible).

    I think you need to learn how different plants grow - and how they can be propagated, whether actively or by themselves. 
    We now have skunk cabbage in our area which has appeared in the last couple of years. That's a bigger problem here than any honeysuckle, because of how it procreates.

    You're tying yourself up in knots about this plant though. I think people will simply stop responding to you if you just keep repeating yourself. There's only so many ways people can answer. Don't grow it if you don't want it. That's how people approach any type of plant they don't like or want.

    The simple, basic answer to the question in the title of your post is No.

    The use of pesticides and herbicides and chemical fertilisers across agriculture and horticulture is the root cause of population crashes in insects and thus birds and other creatures higher up the food chain.

    In your own garden, grow what likes your situation - climate, soil, space - and what doesn't need masses of chemicals to keep it healthy.   Keep your soil healthy with regular applications of manure/compost/mulch so it has a healthy level ofmicro-organisms ensuring fertility.

    Choose simple flowering plants with easy access to pollen, nectar and seeds to feed insects and birds.  Favour climbers, shrubs and trees that produce flowers and fruit that help wildlife and have a variety of flower forms from flat like achillea to deep like foxgloves.

    That is incredibly sad. I'm on a relatively new housing estate and some of the nature still remains. We regularly see bats, sometimes stags and also shrews wandering around in the daytime (where I live used to be a farm field). We still have quite a bit of our birds somehow, there are a lot more cats here than there were so I was wondering whether that may affect it. The caterpillars destroyed my cabbage this year but all of a sudden all of them were gone, so I'm guessing birds had them. 
    Do you live in Scotland?  Must be lovely to see Stags on the Moorlands.

  • @Obelixx I've had native wildflowers in my front garden for a few years now which have always been popular with pollinators. I've barely seen any out there this year, they've all been in the back garden going crazy for the non-native perennials and annuals. I went with a new colour scheme this year and made sure to include as many different flower shapes as possible which has been a popular move. I do feel a bit guilty about having a non-native hawthorn cultivar (I bought it for the autumn colour) but the pollinators seem unconcerned. Don't know that it's all that popular with other wildlife, I haven't seen seen any takers for the berries in the past. Squirrels have been taking my green gages without remorse though.

    @Lyn, come to my garden and you are quite likely to see a stag [ unfortunately ]
    How can you lie there and think of England

    I know,  lucky you,  down south we have those little things,  easily jumping over the fences and eating the plants.
    I don’t know if they’re on Dartmoor though,  I suppose they must be down south as the venison shop in Lyndhurst was always a busy shop.

    I live in a rural village in South East England. There is a woods near me that is known to have lots of stag and deer in it so sometimes you can see them wondering around.
