Getting rid of ivy and shrubs in a border

Just to chuck my 2ds worth in.
In the garden there are a few things I really dislike. One is hard work, like digging unwanted trees/shrubs out. Another, is indisciminated herbicide usage.
The method I use is to take said plant,and cut all stems to just above ground level and then, using a dropper bottle, add 1 or 2 drops of 360 Glyphosate to the end of each stem. If a single or multiple trunks, then a few holes, drilled in the trunk and filled with the same.
The glyphosate is completely contained, the plant dies, and about 1 yr later the remains are often rotten enough to easily break up.
Over the years, I have managed to get rid of rampant Bougainvillea and Rhus (in Australia), and other plants that reshoot from any root left alive.

 

If not Cotoneaster could it be Berberis?

 

I think that all of the Berberis is thorny. It looks like a cotoneaster but all doesn't have berries. I had a evergreen one and it didn't have many.

 

Really if it's going to be dug out does it really matter what it is.

 

Well it would be good to solve the enigma! I'd be able to sleep at night for a start
