Dustin - welcome to Montana! We're glad to have sustainable
minded folks join us here in this little slice of heaven. As a plant lover, I'm particularly exited that one of your first priorities with your land is the restoration of its' vegetative community. Kudos - many people
don't even give a second thought to what plants are on their land, much less have a vision for restoring native communities.
That said, I have a couple thoughts as you 'move in' to your land.
This spring, you will probably notice a lot of ephemeral annuals on your land, that only exist for a couple months of the year. Taking a look at these plants will give you a good idea of what native flowers might be well suited for your area. Take pictures, make notes, maybe even measure a few of your trees. This will give you an appreciation of the 'base case' of your land, and knowledge of what native (and likely some invasive) plants are out there.
The Montana Native Plant Society
has a lot of good resources about native plants
. They have articles about native landscaping, site suitability, a list of sources of native plant material, and good links.
There are various good identification books
for Montana, and our state also has a good online
database of native plants, and invasives: http://nhp.nris.mt.gov/
From your description of your area, you are probably classified as Rocky Mtn Woodland-Steppe transition
or maybe lodgepole pine, to give you a starting point.
The groundcover evergreen on the south slope is probably a type of Juniper.
And although certain parts of your property may be able to support deciduous trees, you are in a drought stricken spot (probably <15" precip a year). Extensive establishment of deciduous may be more hastle than it's worth, although folks on here would probably have a lot to say about getting important deciduous trees established, using biochar
/ organics, and starting from seed to encourage strong taproots.
Please be careful when introducing new species of plants into your landscape. Bamboo may be attractive, but it doesn't fit in with the range around you. Consider the purpose of such things as building dams (ponds) and planting non-native (non-horticultural) plants on your property. Is the benefit greater than the potential impacts?
I don't know what your food production goals are on your property - if you want to establish perennial
food sources, there are fairly limited native plants that provide that. However, there are plenty of native shrubs and forbs that are medicinal
, and / or provide many ecosystem services such as discouraging erosion, encouraging native pollinators, and enhancing soil quality.
Good luck in your endeavors! Sorry for any criticism, but I can't help but have opinions.
