I work in southern California. Most timber projects here are Douglas Fir Larch wood grade. However, when looking through historical wood species and grades. I never know whether to pick DF Larch, DF Larch North or DF Larch South. Can anyone shed some light into this? Thanks.

For example, i occasionally contact Amerhart in Green Bay, Wisconsin - Kevin Huth, 920-494-4744. They are a regional supplier to general contractors as well as DIY Retailers. They may be able to refer you to a supplier in your area.
In my area, among other species, i specify DFL #2. I use the "North" design values from NDS. I also specify the design values Fb=850psi, Fv=180psi and so on, in Header and Beam Schedules, that the contractors must comply with.
Regardless of what species, it is a practice of mine to include the design values in schedules and/or general notes.

Check with your supplier as BSVBD said,
But I'm guessing you'd use DF Larch. I'm from Sacramento, and the firm I work for always used DF Larch.
