We (NZ) got a gift from the UK of gorse bush which now runs pretty rampant, but interestingly it's now being used as a tool for repopulating native plants, as it's hardy nature means it can work as a shield for vulnerable young native plants (https://www.pressreader.com/new-zealand/the-press/20210605/2... is the best source I could find for this, but I walked through that area about 10 years ago which is how I came to learn about it)
