Observations on creating silvopasture

We’ve been working on establishing silvopasture for many years.  We’ve planted trees in what was previously open pasture and thinned trees in what was previously woodland.  We have found it is much easier to add trees to pasture than it is to remove trees from woodland (absent heavy equipment). Woodland requires the removal of a tremendous amount of material to allow for light penetration and grass growth.  We have found 75% tree removal to be a good ball park figure.  On the other hand, trees can fairly easily be added to pasture at the appropriate spacing, and fast growing species such as black locust start adding meaningful shade in 3-5 years.  

What has been your experience?

I have not done silvopasture though it sounds to me like you have maybe trying too hard?

I can see why you would say it's easier to add than to take away.
I work with silvopasture in the professional sphere and i think often people have specific trees they want, and it's also easier to add specific species than to remove others. I've seen great setups with sheep and persimmons, for example (some in old orchards, where only a few trees needed to be removed), and then lines of timber trees, fruit trees, and then pasture where it had previously been a timber plantation and they cut/grubbed out lines of smaller trees to provide the pasture areas. But not everyone has a fleet of industrial logging/grubbing equipment at their disposal!
