One council, three landscapes
Northern Beaches Council replaced the former Manly, Warringah and Pittwater councils and now runs a single set of tree controls from Manly to Palm Beach and inland to Terrey Hills and Duffys Forest. If you are working from older advice that names one of the predecessor councils, it is out of date.
The area contains three quite different working environments. The coastal strip is sand over sandstone with permanent salt exposure. The plateau at Frenchs Forest, Belrose, Davidson and Terrey Hills is lateritic ridge soil carrying the endangered Duffys Forest community. The valleys and escarpments at Bilgola, Avalon, Church Point and Elanora are steep sandstone with houses built down the slope.
What needs approval
Northern Beaches applies protective tree controls with a moderate size threshold and an exempt-species list that covers the usual declared weeds. Pruning beyond routine deadwooding generally needs the same approval as removal.
Three overlays complicate it:
Bushfire prone land covers a large share of the LGA and brings additional considerations for anything near a dwelling.
10/50 vegetation clearing applies only inside the mapped entitlement areas published by the NSW Rural Fire Service. Many peninsula properties are inside; many adjacent ones are not, because the mapping has been narrowed since the scheme began. Check the specific address.
Biodiversity mapping protects Duffys Forest community, coastal upland swamp and littoral rainforest patches independently of tree size.
The trees
Angophora is the signature species — smooth orange-pink bark, constant shedding of bark and small twigs, and a habit of looking far worse than it is. Alongside it, Sydney peppermint, scribbly gum, red bloodwood and, on the better soils, blackbutt.
Along the beachfronts, Norfolk Island pine, coastal banksia and tuckeroo. Cocos palm is widespread in older gardens and is a removal target because its seed spreads into the reserves.
Access
The escarpment blocks are the hard ones. A house at Bilgola or Whale Beach may sit two or three levels below the street with the tree below that again, reached only by stairs. Everything is carried by hand and the chipper stands in the street above. That is where the hours go.
The flats at Dee Why, Cromer, Narrabeen and Frenchs Forest are much more straightforward, with vehicle access to most back yards and room for a tipper at the kerb.
Nearby
Belrose and Cromer have suburb pages, Mona Vale covers removals on the northern end, and the Northern Beaches region page covers the peninsula as a whole. The council index lists the other councils.

Frequently asked questions
Does the old Manly, Warringah or Pittwater rule still apply to my block?
No. Northern Beaches Council has consolidated the three former councils under its own development control plan, so there is one set of tree controls across the peninsula now. Older advice referring to Warringah or Pittwater DCPs is out of date. Work from the current Northern Beaches document.
Can I take out a tree for bushfire safety without asking?
Only inside a mapped 10/50 vegetation clearing entitlement area, and only within ten metres of an external wall of a home. Underlying vegetation may be cleared within fifty metres in the same mapped areas. Outside the mapping, the council's ordinary controls apply regardless of how close the bush is.
What is Duffys Forest ecological community?
An endangered vegetation community found on the lateritic ridge soils around Duffys Forest, Terrey Hills, Belrose and Ingleside. It carries protection independent of the council's tree size threshold, so a modest-looking scribbly gum or banksia on one of those ridges can be regulated where the same tree elsewhere would not be.
