1. Broad beech fern 2. Looks a bit like yellow root, but not quite 3. a tree like hickory that got chomped by deer? 4. Ebony spleenwort fern 5. Dewberry (a Rubus)

Just wondering if it's an interesting native plant or something that will take over if I leave it alone. It's both.

Yes! I think that's it: "Dame's Rocket". Not reported invasive in our area -- so I think I will let it be. Thank-you.

I work in a bush-regeneration crew too, however it is very rare that we do any spraying, this is more to do with the type of plants we are targeting and the approach to the work that we have, than any real aversion to spraying (we use the cut and swab method mostly). I think the advice that you need to get nearly 100% coverage to kill a native plant is somewhat flawed, I would be surprised if any bush-crew has actually tested this theory, because it would involve a very high level of carelessness. There are many native plants known to have a very low tolerance for Glyphosate (Roundup), in fact I would suggest it is one of the worst chemicals for off target damage. Greg, you are right to point out the variables involved, but I would simply say that the more careful you can be with spraying the better, certainly aim for good coverage of the target weed, but there is very little reason why you should need to hit a non-target at all, particularly in a domestic situation where you have all the time in the world to be careful. The suggestion to spray liberally is open to interpretation, it is actually quite difficult to spray as low as the per hectare rate that is indicated on the label of Glyphosate products and the majority of people outside of agriculture are spraying at rates more than double the recommended. Artie, in reference to your question regarding long-term poisoning of the soil, I have a very careful approach to the use of chemicals, but when I bought my house I had a similar kikuyu problem and I resorted to the use of glyphosate, it was a once off, and I planned to plant out the areas and mulch heavily, so I knew I would not be using chemicals year in year out. When you say you have problem along the fenceline, if this is an area where you want absolutely nothing growing you may be looking at the long-term use of chemicals, which could be harmful to your soil. If you dont want a weed problem, you will need to plant something else to offer some competition to the weeds, maybe a low-growing ground cover. Nature hates a void and if you don't plant something, then more than likely a weed will find its way there. Good Luck, mudlark
