Sugar maples? I somehow doubt the climate in Sydney is conducive to producing maple syrup.

Tamaracks are another tree that come to mind that would struggle...

For example, many trees(Pines/Broadleafs) from Southern Hemisphere temperate forests don't grow in hot summer climates, even trough the place have the same winter temperature as the native habitats, this is interesting.

There are several places producing maple syrup in this area - it seems as though the trees produce at a younger age here, than is typical in Cananda and the US, probably due to faster growth rates.

My experience with NZ native trees in Australia, is that they do grow, but that some are susceptible to heat either from dry conditions, or different fungal infections from higher dewpoints.

That's a bit surprising as nobody as far as I know in the Vancouver area is producing maple syrup as the maple trees that grow here aren't the same variety. I was told that the winters here are too wet and mild for sugar maples to produce enough quality syrup at a given time.

I imagine in a place like Sydney or Auckland, there wouldn't be enough of a dormant period for sugar maples to produce well and over time would show signs of stress.

Probably more a case of the winters being too cold in Vancouver. Temperatures need a bit of contrast, with enough warmth for sap flow, and enough frost to concentrate the sugars.

It works in NZ because winters here provide conditions that spring provides in eastern Canada and the US.

I'm guessing Auckland wouldn't be a good climate for syrup production. I cut down a Maple on the driveway about three winters ago, and the sap literally poured out of the cuts.

Yes I would expect sugar maples to go dormant here in winter but it seems it doesn't get cold enough for them with a quick spring warm up to get the sap flowing like you get in eastern canada/US. The excessive winter rain doesn't help either. We do have lots of other kinds of maples here though just none that can produce quality syrup.

I think in marginal climates like here or Vancouver, it's the day time winter temperatures that are crucial.

There are a few different maples around here, which is nice for autumn colour. Just working at a new subdivision (about 800 houses)at the moment, and the vast majority of plantings seem to be deciduous, with plenty of maples and oaks -looks like there must be a no palm policy.

Surely that's not quite what you meant. Quebec has way colder winters than Vancouver and they're the maple syrup capital of the world.

The spring in Motueka isn't frosty enough for production, so (unlike Quebec etc) winter is the season because that that provides the sufficiently warm days and cold enough nights, that maples need for good production.

Vancouver is probably similar to Motueka, in that spring nights aren't cold enough, so would have a better chance in winter, but then the days aren't warm enough.

That's just a guess though, and I would think most of BC would have a decent climate for them.

It seems some here in BC are trying to tap the native big leaf maple to make maple syrup on a local scale. I have never tried it but I am curious about the different taste. I am sure it has a distinctive taste compared to regular maple syrup made from the sugar maple. This is an old article but found it rather interesting.
