Are there any rules for letting farmland turn to wild flower/scrub?
I have ownership of 50 hectares mix of pasture and bush, fully organic. Currently dairy cattle are on it. Rent is negligible, covers rates. Farmer is running it to ruin so am considering letting it go with no cattle on it. Some paddocks would turn to scrub some to wild flower. Any rules to letting it go like this?

Up to you but it's highly likely it will just grow covered in gorse, broom and other pests. Depends on where it is really as climates change from one region to another so try and find some natives for your area.
it’s a decent concern but rebuilding plant/wildlife generally happens in stages and in some cases weeds like gorse are the first to establish themselves, if you give gorse time it will turn into a shelter for other plants that are more sensitive to environment conditions.
So over time you get waves of different plants establishing themselves as the soil becomes more aerated, shelter from wind is created, and nutrients return to soil from degredation of plant bio matter.
at 50 hectares you're likely to get complaints from neighbours to the council about not controlling noxious weeds on your property
you missed the part in the comments where he said he’s doing it by the paddock and not intending to do a full conversion
i didnt downvote you champ
Successional plant assemblages are affected by the existing dominant canopy species.
"Hands-off regeneration" won't have the same result as intentionally planning and maintaining a proper planting regime. I.e., just because you can, doesn't mean you should.
A) he’s looking for something that’s self managed, or maybe managed for him.
B) Gorse does have a selection bias as a nursery plant and favours broadleaf natives over others, but if your choice is: a paddock, (hopefully) wildflowers, gorse seed bombs, and an intensive kanuka rewilding project, he might want to have options
Don’t listen to this. Gorse is a nightmare. Don’t let it go to gorse. Just pulled 3000 broom plants from my block. The work is real. What about working with doc to plant it out. Their jobs for nature programme
lotta doc and other ecology projects use gorse for shelter, they use “seed bombs” to scatter them. It was started by a farmer in 1987 when he successfully reforested some of his land with gorse plant nurseries. It’s old news mate you just have to consider how you do it.

Gorse is actually a great nursery plant for more substantial natives, larger ferns or any trees will outcompete gorse eventually
Can confirm. My dad decided that a steep area wasn't worth clearing of gorse. It now (30 years later) has well established totora and other natives coming through. Gorse is a legume, so it's great for the soil. This process relies on birds dropping seeds, so if you have no other bush near by it will have limited success.
So if there are no seeds the gorse will remain forever?
In my experience, gorse seems to eventually be overtaken by blackberry if nothing grows under it. Cunt of a situation to clear.
Yup. There's a great short doco on an old boy out near Akaroa who has regenerated native bush through this exact method of allowing the gorse to shelter the growing natives
Hugh Wilson of Hinewai Reserve! The documentary is called Fools and Dreamers: Regenerating A Native Forest and is available on YouTube on the Happen Films channel. Well worth a watch if you have a spare thirty minutes.
Thanks!
No. It reeeeeally depends on the area and adjacent seed sources. The succession pathway through gorse is very different than through Kānuka/mānuka and can significantly lower diversity for longer.
This is well worth a read. https://newzealandecology.org/nzje/2811
Also gorse is extremely flammable and leaches nitrogen into waterways.
Yep. Can it be a nursery species? Yes.
Is it naturally a nursery species and where you have gorse will eventually be native? No.
Yes I would have thought it is generally much better to use manuka / kanuka as nursery shrubs. Hell at least the bees would be super happy.
For native bees yes. Honey bees far prefer gorse over manuka/kanuka.
Snap — I just referenced the same paper in response to a different comment lol
Nice one. Hugh Wilson's work is great but it really gave a whole bunch of unqualified people the confidence to give bad advice. Sigh.
Good nuanced take but vs someone running cattle (badly?) on the land? Could the nitrogen leech be worse? The diversity might take.linher than ideal but still better... right?
Yeah for sure, there are a number of factors to take into account. It's more complicated than just saying gorse is a good cover crop though.
Oh yeah but that process he's been doing for years, if OP is planning on keeping their property long term its certainly viable but if its short term planned and controlled native planting would be better
From what i understand gorse is extremely valuable to native bush regeneration, it is only considered evil because it is bad for grazing land not for our native bush.
Check out this doco about Hugh Wilson, everyone called him a mad man but he proved them all wrong.
Fools & Dreamers: Regenerating a Native Forest is a free 30-minute documentary about Hinewai Nature Reserve, on New Zealand’s Banks Peninsula, and its kaitiaki/manager of 30 years, botanist Hugh Wilson. When, in 1987, Hugh let the local community know of his plans to allow the introduced ‘weed’ gorse to grow as a nurse canopy to regenerate farmland into native forest, people were not only skeptical but outright angry – the plan was the sort to be expected only of “fools and dreamers”.
Now considered a hero locally and across the country, Hugh oversees 1500 hectares resplendent in native forest, where birds and other wildlife are abundant and 47 known waterfalls are in permanent flow. He has proven without doubt that nature knows best – and that he is no fool.

I understand and have watched the film, but for such a small plot and likely limited time and resources by OP, planning on such a long process on a likely flat rural area that's had up to 100 years of weeds seeds in the topsoil with probably little to none of the native seeds left anymore would just provide the opposite of what OPs intentions are
Letting it grow back naturally is a choice... even if it goes to gorse and broom. They provide the cover for natives to grow underneath. Only thing is this could take 15 yrs maybe.. idont know exactly hour long, I just remember it was done on Banks Peninsula.
Quickest solution would be to get advise from someone up on conservation management.
Gorse will turn to native after a few years, its actually an accepted method now. Depends entirely on adjoing neighbours though, if you are next to native bush only then you are fine.
One method us to mow the grass right down to the dirt next to the natives and gradually allow the native seeds to take root (manuka etc.)
