Well done to remove 10 m2 of old growth. Sadly dry plants like these have dropped most of their tiny seeds so the next generation has a good seedbank. We need to be taking out green growth to get ahead of this cycle.
Not quite the full 10m2 removed - we ran out of time and steam. We knocked out quite a bit of new growth but, you're right that it will be on our to-do list for a while yet. This site and a couple of patches in Kama paddock (that we've found so far).
