Hi Jason. Welcome! I'm in Bayswater Nova Scotia, just down the shore from you. What part of Halifax are you in? Is that one of the Five Island Lakes behind you?
Looks like a beautiful property! I'm working with existing forest as well, however mostly black spruce here with birch, alder and tamarack.
What's your soil depth like? We have very little and so I'm essentially going to garden on top of the moss and tree roots, mostly adding fruiting shrubs and herbaceous medicinal plants in the understory along with support plants. (Working in large patches, as one of the threads mentioned.)
I may also be able to build up a couple of spots enough to put in a hazel or two or maybe a swamp crabapple. (We're pretty boggy over here.)
My other main strategy is to work along all the sunny edges, making the most of them by putting fruits, nuts or berries there along with helpful guild members... ideally medicinal ones.
I had grand visions at the beginning, just 3 years ago, however things are moving much more slowly. I only realize now that it's actually much better, as everything is integrating in a deeper way.
Keep us posted about what you're doing, including pictures, and how it goes. I also highly recommend walking around and taking a whole set of "before" pictures at this stage.
