Everybody has good ideas, but sometimes they just add to the sense of overwhelm.
I second the recommendation to"
Settle in and wait. Get a feel for where the light, water, wind, and hungry
deer come from. If you want to build some long-term benefit, you might set up a 'nursery' to grow some small (cheap) cuttings or starts of perrenials where you can care for them, before planting them in permanent locations once you've observed the best locations. You can also start building up resources like
compost, wood chip, palettes, fencing, etc. without paying an arm and a leg to do them all at once. Craigslist and posting notes on
local bulletins (like in the feed store, ceramics supply, etc) will get you a lot of things free for the hauling.
Survey for what is already there. When I moved into my grandma's house, I used the chart in the back of 'Gaia's Garden' because it was appropriate to my location in Oregon, to determine what soil-building functions were already there (all of them!) Then I could relax and start adding what made a difference to _me_ instead of feeling like something was missing and it should look different. You also want to consider your own needs - food, water, shelter, fire, future. If there is something missing, or a big problem, you may find it this way and catch it in time.
Start small and close to home. A few successful projects will get you a lot further than big unfinished ones, and what you learn will apply to the next
project. Branch outward as time and interest call you to do so. If you take on too big an area all at once, you will just disturb the ground and invite weeds to take over while you struggle, with disappointing results. Natural succession will usually replace the initial weeds with a balanced ecology. It may not be your favorite plants, but you can keep an eye on it and intervene only if a known problem invasive is trying to take over. If you have good
native groundcovers in place, like strawberries or ginger, you can let things go while you focus your energy on the most exciting project first.
That said, here's a priority suggestion based on what I've wished I'd done in past years:
1) Food garden (because it's planting time right now)
2) Winter wood supply (or whatever your heating-fire eats)
3) Shelter (for you, your tools, and your wood supply - fix any roofs this summer while it's not raining)
4) Clean water on site (Fixing up the ponds, a spring, or rainwater collection - this will save you money and secure part of your future, and it's higher priority if you don't already have potable water on tap.)
5) Build soil. Start near the house, collect biomass, experiment with
biochar, etc.
What a great situation to be in!
Like Brenda says, you can convert some of those downed logs to firewood, building timber, fenceposts, or huglecultur, depending on what kind of wood they are. Nothing wrong with leaving logs and 'slash' (branches etc) in place, it helps the soil more than burning it would. And keeps noxious weeds suppressed while you help perrenial / native / food plants re-establish in the logged-off areas. Blueberries and huckleberries love burned-out clearings if you're in the Pacific NW. Fruit trees in those clearings can be good too. Be sure to control any burns and establish good fire lanes so they can't spread to your house or neighbors.
Have fun, and don't forget to take some 'before' pictures so you can show off what you've accomplished!
