There will be always much more seeds than the ones that will survive at the end. You can rescue seedlings growing in unsuitable areas (next a road for example) that would not survive the lawnmower.
> How much growth per year can I expect?
It depends a lot on the tree and the area, the water available etc. Fast growth is tender and not always desirable. Oaks and other long living trees will put their best efforts to grow under the surface. Don't expect a lot to see the first years but after this phase they will suddenly accelerate. You need first to know what trees are good for your area
If you want fast results, a common technique is to use fast growing / short lived trees and shrubs first (birch or rowan for example). Then seed or wait for other species to reach the area and slowly unfurl.
> How can I provide symbiosis with the nearby protected raised bog and its birds?
Plant fruit shrubs, let dead wood decay in place, use holly and blackthorn to encourage nests...
Avoid spreading invasive Rhododendron in any case.
If you have a bog near your home, the soil could be very poor and acid. This will determine what you can plant and what not. Not all trees can stand a high phreatic level. Willows can, and are easily grown from free cuttings. Rowan are excelent also in acid soils. Most trees will avoid the bog.
Just pick up your own seeds, either plant it or let the nature do gladly the hard work for you.
