<p class="MsoNormal">Here is in BC’s Lower Mainland the minimum protected tree size is, overwhelmingly, DBH
<b>20 cm</b> (8 “). There are of course SPEA’s, which is a whole different kettle of fish. You mentioned a road and they often have ditches and these can be considered “watercoures” so DFO rules may apply (see below for “watercourse"). In terms of minimum tree
size, we do have two North Shore municipalities that are, as one city arborist stated to me, “a city in a forest which runs to Alaska.” These two cities have their protected tree status starting at
<b>10 cm</b> (4 “). That’s basically a weed. That being said, many cities have - and rightly so - rare, unique or endangered trees listed in this tree size; so that’s fair enough. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">At the other end of the spectrum is the West Vancouver tree protection bylaw at
<b>75 cm</b> (30 “). Note, that arbutus (<i>Arbutus menziesii</i>) is 20 cm, as it is Canada’s only native broad-leaved evergreen tree. So that’s fair enough. But given their very slow growth rate, I would have popped that down to 10 cm. Oh well. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I particularly like the City of Burnaby bylaw which stipulates a 20 cm tree if there is a
<i>property development application</i>; for instance, an apartment building construction. And for non-development applications i.e. you just want to get rid of some trees on your property, then it’s 30 cm for evergreen and 45 cm for deciduous. The idea being
that the two equate for stormwater interception. I sort like that concept, and it’s the only municipality here that does that. I think that they are ahead of their time, although I would like to see those two numbers reduced a little lower, perhaps 10 and
20 respectively. Lastly, there is the City of Maple Ridge, an up and coming Vancouver suburban neighborhood. They too have the 20 cm, but go a step further to state that “significant trees” are 50 cm (urban and suburban), and 70 cm (rural). Hmm…not a bad idea.
Incidentally, urban and suburban include “Urban Residential, Estate Suburban Residential, Suburban Residential, Urban Reserve, Commercial, Industrial, and Institutional. Rural is everything else. <o:p></o:p></p>
